Prosomeric ModelView all 15 articles The trigeminal column is a hindbrain structure formed by second order sensory neurons that receive afferences from trigeminal primary (ganglionic) nerve fibers Classical studies subdivide it into the principal sensory trigeminal nucleus located next to the pontine nerve root and the spinal trigeminal nucleus which in turn consists of oral this column would be subdivided into segmental units derived from respective rhombomeres Experimental studies have mapped the principal sensory trigeminal nucleus to pontine rhombomeres (r) r2-r3 in the mouse The spinal trigeminal nucleus emerges as a plurisegmental formation covering several rhombomeres (r4 to r11 in mice) across pontine retropontine and medullary hindbrain regions In the present work we reexamined the issue of rhombomeric vs we analyzed its subdivisions in an AZIN2-lacZ transgenic mouse known as a reference model for hindbrain topography together with transgenic reporter lines for trigeminal fibers We screened as well for genes differentially expressed along the axial dimension of this structure in the adult and juvenile mouse brain This analysis yielded genes from multiple functional families that display transverse domains fitting the mentioned rhombomeric map The spinal trigeminal nucleus thus represents a plurisegmental structure with a series of distinct neuromeric units having unique combinatorial molecular profiles The rostrocaudal organization of successive Pr5 and Sp5C units raises the question of the possible correspondence of their mutual boundaries with interrhombomeric limits the hypothesis may be considered that the underlying rhombomeric scaffold may actually establish a finer segment-by-segment organization of the trigeminal column it is possible that the segmental units of the trigeminal column develop characteristic molecular and cellular identities with probable neurochemical and/or functional implications On the whole we propose a novel segmental map of the mouse trigeminal column according to gene expression characterizing it as a plurineuromeric modular complex in relation to a series of rhombomere-derived domains and care of laboratory animals were conducted in compliance with the current normative standards of the European Union (Directive 2010/63/EU) the Spanish Government (Royal Decree 1201/2005 and 53/2013; Law 32/107) and had the approval of the University of Murcia Committee for Animal Experimental Ethics We used adult brains of a heterozygotic mice line developed at the Department of Biochemistry, School of Medicine, University of Murcia (López-Garcia et al., 2013) These mice express recombinant beta-galactosidase protein under control of the Azin2 promoter vibratome 120 μm thick serial sections were obtained Serial sections were obtained in either sagittal or horizontal planes Floating sections were then reacted for beta-galactosidase and were finally washed Digital microphotographs were acquired using Aperio CS2 technology (Leica Microsystems GmbH This database provides images from transgenic mice lines with EGFP as reporter for the expression of diverse genes According to the recorded GENSAT procedures the brain sections were processed for immunohistochemistry against EGFP which normally leads to full labeling of the positive neurons including their soma and fibers We searched for genes expressed in the trigeminal ganglion whose axons reach the brain and form the ascending and descending trigeminal tracts delimiting in this way the extent of the trigeminal sensory column and cropped them to show our region of interest We searched the AMBA and ADMBA for genes whose respective in situ hybridization (ISH) experiments included both sagittal and coronal section series at P561 as well as sagittal section series from stages P4, P14, and/or P28.2 We screened these image series visually selecting the genes with significant expression within subregions of Sp5 This analysis was initially carried out by two of the authors independently whose preliminary results were discussed to reach a consensus Our criteria to select genes was firstly that they displayed discrete expression patterns with positive and negative regions visible along the longitudinal axis of Sp5; secondly we checked that these patterns were coherently reproduced in both sagittal and coronal P56 stage series part of the image series from these juvenile stages displayed generalized low ISH signal or high background so that these image series were discarded from analysis As a result, we identified 12 genes (Table 1) that were differentially expressed in the trigeminal column including the brightfield microphotographs or scanned images as well as their respective counterpart with color-coding of the expression level both of them available for each brain section the positive cells appear with a blue precipitate accordingly to standard ISH protocols The sections corresponding to juvenile stages (P4 and P28) are counterstained with HP Yellow In the color-coded images from adult and juvenile stages the expression intensity ranges from blue (low expression intensity) through green (medium intensity) to red (high intensity) Summary of the expression of each gene in the rhombomeric portions of the trigeminal column We downloaded the images that included the whole or part of the trigeminal column cropping them to show the region of interest the images from parasagittal sections are oriented with the rostral end to the left while those from coronal sections are details of the

cuneatus nucleus (ECu) Amb and LRt- are indicated as reference landmarks (A,D,E,H–N) Scale bars = 500 μm; (B,C,F,G) scale bars = 300 μm The molecular mappings showed that the genes Baiap3 and Camk2a are expressed selectively in KF, while they show no significant expression in Pr5 (Figures 4A,B,D and data not shown). On the other hand, Irx2 is expressed by the Pr5 cells of r2, with no expression in KF (Figure 5A) These patterns thus delimit the r1/r2 boundary as the rostral end of the trigeminal column This region is primarily characterized by the mass of the migrated pontine nuclei aggregated at the ventral surface of r3 and r4; they originate at the rhombic lip from rhombomeres r6-r8 (Di Meglio et al., 2013; Tomás-Roca et al., 2016; Figure 3) As regards our molecular characterization, Irx2 is expressed in the r2 portion of Pr5, with some disperse cells within r3, as can be observed in adult and juvenile sections (Figures 5A–H and Table 1) this gene marks a rhombomeric subdivision of Pr5 in some sections Baiap3 appears expressed in scarce cells in r2 as compared to r3 (data not shown) Similarly, Calb2 is significantly expressed in the r2 and r3 portions of Pr5, together with some positive cells in r4 (Figures 10J–L) Irx2 and Kcng4 display also expression in more caudal hindbrain regions abuts the first myelomere or spinal cord segment (my1) occupied ventromedially by the pyramidal decussation (pyx) The rostrocaudal axis of the medulla oblongata follows more or less a straight horizontal direction Its pronounced curvature (together with possible variations in the angle of the sectioning plane) causes that coronal sections through r11 or even r10 cross obliquely the hindbrain/spinal cord (r11/my1) boundary including thus the pyx in the same sections than the caudalmost rhombomeres the boundary between the interpolar and oral subnuclei of Sp5 is uncertain on a morphological basis so that in the literature it has been located tentatively at different positions (see section “Discussion”) The dorsal horn of the first 2 myelomeres or cervical segments (C1 and C2) is functionally a continuation of the caudal subnucleus of Sp5 as commented above; it receives the terminals of the descending primary trigeminal afferents and has a largely similar cyto- and myeloarchitectural aspect In our molecular mappings we noted a continuous pattern from r10/r11 to my1 concerning the expressed genes and their laminar pattern so that in our figures showing gene expression we have drawn the contour of Sp5 as including the dorsal horn of my1 The eventual continuation of this pattern into my2 could not be ascertained in the studied material since seemingly the analyzed sagittal or coronal brain sections included only down to my1 Tac2 is expressed only in the gelatinous layer of the caudal subnucleus of Sp5 (Figures 9D–F). It displays a regionalized pattern within this subnucleus, with substantially fewer positive cells in r10 than in r11 or my1, as observed across juvenile and adult stages (Figures 9D,F; also compare Figure 9E with Figure 9B from the analyzed genes Tac2 is the only one displaying a rostrocaudal regionalized pattern within the caudal Sp5 as compared with the homogeneous rostrocaudal expression of the aforementioned Baiap3 and Tac1 Considering the set of r7, r8 and r9 Sp5 domains (that is, the medullary part of Sp5, after excluding the caudal subnucleus), it is jointly characterized by Irx2 expression, present as a shared pattern of scattered positive cells, in contrast with the absence of expression in the rest of Sp5 (the retropontine region -r5 and r6- and the caudal subnucleus -r10 and r11) (Figures 5E–H) We have described genoarchitecturally a segmental pattern of the trigeminal column attending to morphologic landmarks of the different rhombomeres and to the regionalized expression of genes that show specificity for one or several rhombomeric domains we comment our results in the context of previous studies and knowledge about trigeminal subdivisions hindbrain segmentation and molecular markers of trigeminal neurons the oral and interpolar Sp5 subnuclei would consist of the r4-r6 and r7-r9 portions of the plurineuromeric trigeminal column Therefore, considering these multiple rostrocaudal subdivisions of Sp5, plus the modern concept of a neuromeric hindbrain (Tomás-Roca et al., 2016; Martínez-de-la-Torre et al., 2018) a rhombomere-based framework needs to be developed that should facilitate the finding and characterization of trigeminal functional units which apparently remain partly hidden if only the tripartite classic schema is assumed An advantage of the rhombomeric model is that it would be underpinned by modern embryological and molecular criteria Such a model would be also a basis for interspecies comparison taking into account the conservation of the rhombomeric (neuromeric) pattern across vertebrates but later the descriptor “cryptorhombomeres” was thought to be more appropriate since these units are not false neuromeres only separated by given molecular properties these data suggest the existence of subtle molecular differences starting with differential Hox gene properties within the medullary and spinal portions of Sp5C which may lead to functional properties that would need to be explored Some of the molecular markers we report (Calb1 Tac2) have been previously described in relation to the regionalization of the trigeminal column A significant novelty of our study is the identification of a segment-like portion of the interpolar subnucleus (r9) that is positive for Calb1 and negative for Calb2 This had not been noticed previously possibly because the scarce use of parasagittal sections in classical neuromorphological analyses Another calcium-related gene, Camk2a (calcium/calmodulin-dependent kinase II α) is functionally involved in nociceptive pathways, as deduced from the study of mutant mice (Zeitz et al., 2004) It was described as expressed in neurons of the marginal and gelatinous layers of the spinal dorsal horn as well as in unmyelinated neurons of the trigeminal ganglion We show now that its expression extends to the superficial layers of the caudal Sp5 subnucleus in r10 and r11 with a pattern similar to that described in the spinal cord in addition to the expression in the non-laminar segment-like portion of the interpolar Sp5 in r9 This latter expression would support the correspondence of the r9 portion with the “caudal/interpolar transition zone,” which is involved in pain processing Tac1 and Tac2 encode, respectively, the neurotransmitters substance P and neurokinin B. Both genes, or their protein products, have been described in the superficial laminae of the dorsal horn and caudal trigeminal subnucleus (Del Fiacco and Cuello, 1980; Ribeiro-da-Silva and Hökfelt, 2000; Mar et al., 2012) We have found that their expression patterns display segment-related differences with Tac1 reaching up to the r10 trigeminal portion in a homogenous pattern and Tac2 showing less positive cells in r10 It would exist also the possibility of a role in the differentiated mature neurons where it is expressed all of which are involved in hindbrain segmentation Our results show that Mafb maintains its expression in the trigeminal derivatives within r5 and r6 in the adult brain suggesting additional roles in these neuronal populations Fn1 encodes the extracellular matrix component fibronectin. Its mRNA expression appears in telencephalic migrating neurons while in the adult brain it is restricted to the subiculum (Sheppard et al., 1995; Kashima et al., 2019) we describe that it is additionally expressed at least within given segmental portions of the trigeminal column Its possible function in these neuronal populations would need to be tested Pde1c encodes the calmodulin-dependent cyclic nucleotide phosphodiesterase and is expressed in olfactory sensory neurons (Yan et al., 1995), in migrating neurons in the cerebellum and cerebral cortex (Gong et al., 2003), and in lamina I neurons of the dorsal horn involved in nociception, principally at lumbar levels (Torsney et al., 2006) our results show a specific expression of this gene in the r9 part of Sp5 delimiting the caudal/interpolar transition zone We have described a novel feature of the expression pattern of this gene namely its specific location in a single rhombomeric domain (r9) We have described a strong and specific expression in the caudal Sp5 trigeminal nucleus so that it might have a role in the nociceptive function of this region we have tentatively traced the interrhombomeric boundaries within the mouse trigeminal sensory column according to current knowledge collected in the prosomeric model based either on descriptive morphologic or molecular gene expression data or on experimental approaches involving fate maps with avian chimeras or transgenic mice Some of the dispersed sparse populations described in some parts of the trigeminal column may correspond to cells migrated tangentially from neighboring rhombomeric modules where a similar labeling is massive in order to ascertain precisely our delimitation of the rhombomeric domains as well as possible cell migration or intermingling across rhombomeric limits it would be necessary to perform future ad hoc experiments These would ideally combine our reported genetic markers of trigeminal subdivisions with experimental fate maps for each rhombomere One difficulty we encountered was the obliquity of some interrhombomeric limits due to the pontine and cervical flexures of the neural tube (Figure 1A). Moreover, it should be remembered that the rhombomeric domains are known to adopt a degree of obliquity with respect to the mediolateral axis (Figure 1B) with their medial parts displaced anteriorly with respect to their lateral portions These circumstances cause that standard coronal sections are necessarily variously oblique in relation to rhombomeric domains and their limits We have tried to solve this handicap in coronal sections by taking into account the well-known rhombomeric landmarks found relatively close to the trigeminal column like the trigeminal and facial motor nuclei or the fibers of the facial and vestibulocochlear nerves our rhombomeric map is consistent with the observations in sagittal sections which display well some of the mentioned deformations An issue that would require further insight is the possible dorsoventral regionalization within each of the trigeminal rhombomeric domains related to mandibular the dorsomedial portion of the Pr5 and Sp5) together with a more exhaustive molecular characterization of the radial layering in the caudal subnucleus of Sp5 It would also deserve further study the transition from the medullary to the cervical portions of the caudal subnucleus considering that it crosses over such a significant landmark as the brain/spinal cord junction we have succeeded in reporting segmental (transverse rostrocaudally ordered) subregions along the trigeminal column based on molecular and fate mapping criteria delimiting rhombomeric domains Our results are reliable since they are reproduced from sagittal to coronal section series of the adult brain We focused this analysis on the adult brain so that the segmental map should not be regarded as a transient developmental state but as an instance of the neuromeric pattern persisting in the mature brain This mapping of the trigeminal system can provide the basis for further functional and/or pharmacological studies considering the molecular and embryological uniqueness of the different rhombomeric subdivisions of this structure The animal study was reviewed and approved by the University of Murcia Committee for Animal Experimental Ethics MM-D-L-T prepared and processed the

Property of Tavana LLC Metrics details Defining the trajectory of cells during differentiation and disease is key for uncovering the mechanisms driving cell fate and identity trajectories of human cells remain largely unexplored due to the challenges of studying them with human samples we investigate the proteome trajectory of iPSCs differentiation to hepatic stellate cells (diHSCs) and identify RORA as a key transcription factor governing the metabolic reprogramming of HSCs necessary for diHSCs’ commitment Using RORA deficient iPSCs and pharmacologic interventions we show that RORA is required for early differentiation and prevents diHSCs activation by reducing the high energetic state of the cells While RORA knockout mice have enhanced fibrosis RORA agonists rescue multi-organ fibrosis in in vivo models RORA expression correlates negatively with liver fibrosis and HSCs activation markers in patients with liver disease This study reveals that RORA regulates cell metabolic plasticity suggesting that understanding the trajectory of HSCs in development and disease may help to identify molecular pathways suitable for preventing HSCs activation or promoting the regression to a quiescent phenotype thus mitigating fibrogenesis in chronic liver diseases we performed a time-resolving proteome characterization of iPSCs to functional HSCs (diHSCs) which mimic phenotypic and functional characteristics of primary human HSCs we identified RORA as a TF regulating both diHSCs differentiation and favouring the maintenance of a quiescent phenotype by modulating the metabolic state of the cells downregulation of RORA mediates a metabolic switch increasing glycolysis and mitochondrial oxidative phosphorylation system (OXPHOS) we confirmed the anti-fibrogenic role of RORA in hepatic and extrahepatic pericytes thus positioning RORA as a potential antifibrogenic multiorgan target this work shows the potential of studying cell trajectories along differentiation and disease progression this broad characterization enabled the construction of a proteomic roadmap detailing the differentiation of diHSCs from iPSCs these data confirm that iPSCs progressively acquire the stellate proteomic phenotype along differentiation thus enabling the use of diHSCs to further investigate their role in cell commitment and disease Principal component analysis (PCA) of the proteome differentiation profile showed a time-dependent distribution of samples along the differentiation process (Fig. 2A). Proteins comprised in PC1 explained stellate cell commitment across time, as cells gained in proteins related to collagen metabolism, ECM organization, or wound healing processes. A Principal component analysis (PCA) of the proteome during differentiation reveals a time-dependent separation of data indicating distinct stages of the differentiation process B Pearson correlation analysis identifies three phases of differentiation towards diHSCs: Phase 1 from day 0 (D0) to day 4 (D4) and the final maturation phase (Phase 3) from day 8 (D8) to day 12 (D12) C Dot plot showing protein enrichment throughout the differentiation process D Volcano plot comparing phases 1 and 2 highlights the enrichment of mesothelial markers (DESP WLS) and transcription factors (TFs) predicted in silico to regulate this transition E Volcano Plot showing the comparison between phases 2 and 3 shows an increase in collagen and extracellular matrix (ECM) proteins (COL5A1 along with predicted TFs modulating this transition F Volcano plot displaying the differentially expressed proteins between phase 3 (diHSCs) and primary HSCs as well as the in silico predicted TFs involved in regulating the adult hepatic stellate cell phenotype G Transcriptomic comparison of primary human activated and quiescent stellate cells with diHSCs focusing on the predicted TFs modulating the adult stellate cell phenotype These results indicate that the diHSCs differentiation takes place in three main phases which mimic key stages of embryonic development During diHSCs differentiation, the gene expression of RORA showed a significant increase at day 4 of differentiation and progressively declined at days 6, 8, 10, lowering the pHSCs expression at day 12 (Fig. 3A).

determined by One sample t and Wilcoxon test These findings suggest that RORA plays a pivotal role in regulating cellular metabolism during diHSCs differentiation these data indicate that RORA might act as a transcriptional regulator of the mesoderm and mesenchymal specification these results position RORA as a potential transcriptional regulator of mesoderm and mesenchymal differentiation and key for the acquisition of the quiescent phenotype of diHSCs Differentiated cells treated with the RORA agonist SR1078 showed enrichment in the signature of predicted genes these results suggest that RORA plays a role in the deactivation of diHSCs and the maintenance of the quiescent diHSCs phenotype which can be mediated by blocking metabolic adaptations required for HSCs activation A Oxygen

one comparisons and ANOVA 1-way test was performed in the comparison of three experimental groups therefore suggesting that RORA’s influence on mesoderm differentiation may be context-dependent these results indicate that RORA acts as a metabolic modulator in diHSCs trajectory which impacts the phenotype of diHSCs at different stages including initial cell commitment and the quiescent cell identity at the end of differentiation These findings suggest that RORA agonist treatment promotes a lipidomic profile consistent with quiescent stellate cells A Schematic overview of a CCl4 fibrotic

expression of Rora and fibrogenic markers (Acta2 and Col3a1) and the hypertrophy marker Acta1 in 5 ISO mice and 5 ISO and RORA agonist mice group suggesting a positive effect of RORA agonism against cardiac fibrosis independently of hypertrophy development These results indicate that pharmacological activation of RORA is a promising strategy to mitigate fibrosis in multiple organs demonstrating the therapeutic potential of targeting RORA to control fibrogenesis Gene expression data is presented as mean ± SEM Correlation analysis data was performed using pearson correlation analysis we aimed to understand the differentiation trajectory of hepatic stellate cells (HSCs) from iPSCs to mature phenotype leading to the identification of key molecular drivers for diHSCs identity and activation Understanding HSCs paths in differentiation and activation is essential to delineate how cells acquire their phenotype and how this is lost during disease thereby providing pathophysiological insights for the development of novel anti-fibrogenic treatments While animal models have advanced our understanding of disease progression translating these findings to humans remains complex and embryonic differentiation trajectories are difficult to fully capture Human iPSC differentiation protocols offer a valuable alternative enabling the study of dynamic cell paths during differentiation we performed a time resolving proteomic characterization of the differentiation of diHSCs leading to the identification of a unique protein signature of this differentiation the comprehensive proteomic data generated in this study will be a useful resource for researchers interested in understanding different aspects of the biology of human HSCs and fibrosis we lacked a detailed understanding of the human development of HSCs and therefore we cannot ensure that diHSCs differentiation is faithfully recapitulating all the features and the natural path of the human embryonic development our results indicate that RORA is not only implicated in diHSCs differentiation and maturation Although their role at the different stages of HSCs maturation is not totally understood these observations are consistent with our findings where we also find RORA upregulated at initial stages of differentiation and downregulated during activation suggesting that they may play a role throughout development and disease This highlights the potential of iPSC-differentiation approaches for investigating cell trajectories and diHSCs are therefore a powerful tool that may be useful for better understanding the molecular drivers of cell differentiation and disease ChIP-Seq analysis of RORA would have been valuable for further insights but despite efforts suboptimal antibody quality for these assays or inefficient capture prevent the analysis A core feature of fibrosis is the activation of fibrogenic cells which undergo significant metabolic changes during activation Our data suggest that diHSCs serve as a model for pericytes in other tissues and that RORA regulates pericyte activation in multiple organs making it a promising therapeutic target for anti-fibrogenic treatments therefore suggesting a downregulation in fatty acid production diHSCs treated with SR1078 shifted their lipidomic profile towards a more quiescent phenotype confirming the role of RORA in regulating lipid metabolism in diHSCs using two in vitro models we found that activated diHSCs showed an increase in OXPHOS and glycolytic flux as compared to the cells treated with RORA agonist thus reducing the metabolic requirements of the diHSCs and preventing their activation our results showed similar results at early stages of differentiation as iPSC-RORA+/- presented a metabolic profile characteristic of undifferentiated cells that was modified when treated with the RORA agonist indicating that RORA regulates the metabolic activity during early stages of differentiation These results indicate that metabolic flexibility is essential throughout the diHSCs differentiation trajectory and impairs the final phenotype of the cell This metabolic regulation is mediated in part by RORA as alterations in RORα transcriptional activation are implicated in modulating the cellular physiological state Our study proposes that changes in RORA expression levels are one of the underlying causes of the observed metabolic state alterations in HSCs and therefore is responsible for the repression of activation being a potential target for anti-fibrogenic therapy our study underlines the importance of examining cell trajectories during both differentiation and disease We show that HSC differentiation and fibrosis mechanisms can be effectively modeled using iPSC-derived cells enabling the identification of key transcription factors like RORA that regulate cell identity and fibrogenesis and can lead to the development of new therapeutic strategies to mitigate fibrosis across multiple tissues iPSCs cell

livestock banana market consists of imports from Mexico such as Hurricane Grace which hit Veracruz in August 2021 and resulted in farmers having to spend their savings to rebuild their plantations because there was no federal support; and the increase of 200-300 percent for fertilizer due to global supply chain problems and the conflict between Ukraine and Russia stated that production costs are $2.50-3.00 pesos per kilo while it is sold at the market for 80 cents He said the surplus in Tabasco has flooded the national market and the frosts from December 2021 caused the banana in the region to be affected and unable to compete in quality and that causes it to lose value in the market because it no longer turns yellow Veracruz is the fourth largest producer in the country Get

story was published in collaboration with La Voz Chicago the CEO and founder of CashDrop—an app designed to offer businesses a free mobile storefront that allows customers to eat the fees rather than the businesses—outlined a vision for the kind of company he wanted to build The once-undocumented immigrant from Mexico wanted to create an app that would give back to the Latino community “I’m not just interested in the money,” Ruben Flores-Martinez said The CashDrop platform can be adopted by small mom and pop shops and has been marketed to Latino communities in the U.S via Spanish-language ads on social media.  Locally, the app has been used in events like Chi Michelada Fest 2022. Even nonprofits like Healthy Hood Chicago have announced they will exclusively use CashDrop.  Recently, the app hosted a bilingual workshop alongside the Little Village of Commerce at which 22nd Ward Alderperson Michael Rodriguez encouraged street vendors to go cashless with the app as a way to mitigate robberies.  “America has this real obsession with growth,” Flores-Martinez said in the Harvard case study you have to be careful with it.’ Companies can get put into this fasttrack to keep pushing and spending more money until you lose control of where the company is going and just crash CashDrop has been good to Flores-Martinez. It landed him on the Forbes 30 Under 30 2021 Social Impact class list and most recently, in the Crain’s Chicago Business 40 Under 40 class of 2022. By mid-2020, CashDrop had raised around $2.7 million from investors such as Harlem Capital, Long Journey Ventures, and Michelle Phan. According to PitchBook the latest round of investment this past November netted CashDrop more than $11 million.  three former CashDrop employees have collectively taken to social media to denounce workplace bullying and a lack of transparency from Flores-Martinez At least one of these and another former employee said the stress of working at CashDrop led to hair loss South Side Weekly and La Voz Chicago interviewed these and other former employees of CashDrop joined CashDrop as an affiliate in July 2021 and eventually became event manager for the company “Me being Latino and all the employees being Latino was something that I wanted to be a part of,” he said in a testimonial he shared on Instagram.  Trejo was sold on the dream of becoming a millionaire, which was something he said Flores-Martinez would constantly tell his employees that he wanted to see them become. In May, Trejo would bring in one of the company’s biggest promotional events, a car show held in Georgia featuring hundreds of cars and bikes with general admission tickets starting at $250 “That’s where things took a turn,” Trejo stated in the video Trejo said he had made a verbal agreement with Flores-Martinez in which Trejo would keep one hundred percent of commissions from the event But the verbal agreement was apparently not honored—instead Trejo said he received around fifty percent of commissions from the event Trejo said there was never any paper trail for these decisions which according to former CashDrop employees was not out of the norm at the company.  Trejo said he also did not receive reimbursements for some work trips and activation expenses he had paid for out of pocket Multiple employees said company credit cards were often declined forcing them to cover costs on multiple occasions especially during out-of-state trips.  Trejo was laid off and told that the company could not afford to keep him CashDrop’s proposed severance package included only a healthcare stipend for twelve weeks far less than what Trejo felt was owed to him Trejo had to sign the agreement that included a nondisparagement clause that would have prevented him from criticizing CashDrop publicly It’s a really disrespectful offer considering the verbal agreement that Ruben had with me regarding 100% commissions….I won’t be signing anything and I will exercise my right to speak freely about my experiences at CashDrop on social media and to the public Sign up to get the Weekly Digest delivered to your inbox disrespect you and punch down on you daily Trejo wanted to bring attention to his experiences and reached out to other former employees wondering if what he had gone through was shared.  He soon found former colleagues who said that Flores-Martinez had verbally harassed them “They all kept telling me the same thing,” said Trejo “They kind of sparked something inside of me to put a stop to this.” He encouraged them to come forward and build public outcry on social media platforms Ashley De La Torre and Jaqueline Rodriguez who had been at CashDrop under a year and had since left the start-up They came forward recounting instances of verbal abuse and a toxic work environment that they said led them to walk out indefinitely Their videos were liked by hundreds of people and received dozens of supportive comments.  “He would be very stressed out when it was close to paying the bills,” said Rodriguez who remembered Flores-Martinez lashing out as regularly as once a week but especially in the final and first weeks of the month.  Flores-Martinez’s behavior described in the testimonials and interviews took the form of ridiculing interns and in one instance patting an employee on the head.  “It’s unfortunate how much violation became normal—how being violated by a CEO how the emotional abuse just kind of became a part of the day,” said De La Torre in the Instagram video.  In an interview with South Side Weekly and La Voz Chicago Flores-Martinez denied the allegations.At first Flores-Martinez said the allegations were due to “a combination of misunderstanding there’s definitely a lot of emotions involved,” but later called them “completely baseless” and that he was considering legal action.   there’s nothing there,” said Flores-Martinez thirsty for blood to cancel somebody.”“Am I an explosive character It depends on how you slice the apple,” he said where there are disagreements.” But he denied ever threatening employees or making them feel oppressed or controlled Lisa Kowalczyk was part of the company’s customer success team and had joined CashDrop in January 2021 she and other CashDrop employees received a company-wide Slack message alerting them that ex-employees were criticizing the company on social media and demanding that current employees sign an NDA within two hours—or be fired.  Kowalczyk told Flores-Martinez that she had forwarded the document to her lawyer to review.  Before she could get a response from her lawyer Kowalczyk said she was terminated two days later De La Torre and Rodriguez shared their testimonials on Instagram Kowalczyk said she suffered a work-related injury while on a work trip and that she never got the medical insurance to cover it that she was promised She said around $10,000 in reimbursements are still owed to her from instances when company cards didn’t work and that paychecks didn’t come on time on three separate occasions the most recent being just before this past Christmas.  She also recalled not getting support when one of her coworkers was terminated because there was nobody else even qualified that could help me,” Kowalczyk said.  She said the stress from the job eventually led to hair loss and other medical problems.  “There was a lot of blurred lines in the boundaries of work-life balance—where work ends and begins,” said De La Torre adding that it was not out of character for the CEO and employees to drink on the job and constantly be told that they were a family.  stating that she and her colleagues “trauma bonded” and felt as if Flores-Martinez had isolated them from their lives According to a 2021 survey from the Workplace Bullying Institute (WBI) thirty percent of adult Americans are bullied at work a number that at the time of the survey amounted to almost 49 million workers across the country.  The numbers for women working in tech are even more staggering. A 2020 study from Women Who Tech found that close to fifty percent of women working in tech experienced harassment with forty-two percent reporting that harassment was perpetrated by a supervisor.  and therefore we treat it as not worthy of attention and we need to start paying attention because it’s harming millions of workers,” said WBI director and social psychologist Dr WBI is currently lobbying to pass the Healthy Workplace Bill in Massachusetts and New York “to prevent and correct abusive work environments.” The bill was introduced in Illinois in February of 2021 but has not passed the Illinois House of Representatives.  When concerns were brought up to Benjamin Vear the company’s president and the person who handled HR-like responsibilities according to employees employees said Vear reduced Flores-Martinez’s outbursts to the CEO being stressed due to lack of investors.  Vear declined to comment or be quoted on the record Team dinners at the expense of the CEO at notable Chicago restaurants like RPM Steakhouse and Fulton Market Kitchen would later be leveraged in public shamings during company meetings Employees felt stuck because some uprooted their lives and moved to Chicago for the job while others lacked confidence to find a better workplace.  “Ruben was very intentional with who he picked to be around,” said Rodriguez adding that his employees were mainly young Latinos belonging to marginalized communities In response to an email that listed the allegations included in this story Flores-Martinez wrote about the company needing to let go some employees last year for economic reasons “We can’t and will not comment on specific statements made by current or former employees.” In the end he claimed the questions contained “inaccurate” and “verifiable outright falsehoods” but declined to clarify what specifically he objected to “We wish you the best of luck in sorting fact from fiction,” the email ended Flores-Martinez said he wanted to give “opportunities to people that look like [him] in a world where none of them would get opportunities,” adding that “perhaps they think I’m an asshole not everybody’s gonna agree [with] the way that I move Multiple employees said their health declined because of working at CashDrop.  “My mental health deteriorated quickly,” said Rodriguez “I would be extremely anxious because I had not finished a deadline or was nervous about the next day nervous that I was going to get yelled at.” Former employees said deadlines and expectations were often changed last minute and with little notice by Flores-Martinez Kowalczyk recounted a time in which she asked for clarification and Flores-Martinez said,  “that’s not my fucking job Namie said stress and hair loss are real responses to abusive conduct A laundry list of health concerns can stem from verbal abuse including stress-related physical diseases They’re reporting war wounds,” said Namie upon learning of the allegations “Why should you suffer emotional injuries in exchange for a paycheck?”  After going public with their experience at CashDrop, the three employees who shared their stories received words of encouragement, and some vendors like Shop Ankata stopped using CashDrop altogether But they also faced pushback from Flores-Martinez and others at CashDrop in texts and social media posts that attacked the former employees’ characters Flores-Martinez took to his personal Instagram to post a series of stories including one where he wrote “People can say whatever they feel like for their 5 likes and 10 minutes of mini clout.” who worked as a supervisor within the company and had a closer working relationship with Rodriguez left voicemails and text messages invalidating Rodriguez’s testimonial “you did your thing and rode that wave for a free laptop “You’re a slime and don’t do no work,” and “Your child doesn’t deserve his dad to tarnish his image on Ig for likes He doesn’t know he will probably be a slime like you too.” Brewer Flores declined to comment for the story their intent in speaking out is to hold Flores-Martinez accountable.  and realizes that he’s really taking advantage of those around him,” said De La Torre.  Yet Flores-Martinez’s continued denial of any wrongdoing and apparent refusal to engage with the criticisms makes them feel like things won’t change—and if they don’t they believe CashDrop should cease to exist “Abuse is at the fundamental core of it all and Ruben has made it a point to be intertwined with the company so it doesn’t change what I think should happen to CashDrop which hopefully is to be dissolved,” said Rodriguez.  “Even when evidence is tacked against him his ego won’t let him be the better person,” said Trejo CashDrop is used by vendors based in cities around the country Vendors using CashDrop are later reimbursed processing fees.  Kowalczyk said some vendors were still owed those fees when she left CashDrop including a business belonging to a friend she brought on.  She said the apparent financial troubles at the company—delayed paychecks and layoffs—didn’t add up to what she described as Flores-Martinez’s lavish lifestyle.  “There are $15,000 spent on tequila for parties maybe another $20,000 spent at a club in Miami,” said Kowalczyk “There’s no reason for a CEO of a new startup to be staying at the Beverly Hills Hilton.” The former employees have concerns for the vendors still trusting CashDrop with a portion of their business. Customer fees were most recently advertised at five percent with a minimum charge of forty-five cents this is because the fees were changed—a move that has not been reflected in CashDrop’s public-facing platforms.  CashDrop actually raised the rate that they charge the customers their convenience fee,” said Kowalczyk.  Flores-Martinez said the fee is “dynamic” and in some instances “the pricing can be as high at fifteen percent.” He assured the Weekly that CashDrop is completely transparent with its merchants and “if there was cracks in the systems What’s more concerning to the group of former employees who have spoken out is the newly launched Latino Renaissance Fund Flores-Martinez pledged $1 million of his own CashDrop equity to be distributed to 1,000 Latino-owned businesses who use the app.  Something similar was promised to employees at CashDrop who never received paperwork for the equity they were told they would receive in the company “If you’re going to be working under the pretense of being Latino Renaissance you got to treat Latinos right,” said Trejo “We’re not gonna take it especially from somebody that’s not even from Chicago.” Though Flores-Martinez moved to Chicago from Milwaukee he views himself as “a prominent member of the Latino community in Chicago.”  [from] the fucking intern all the way to the mayor,” he said When asked if he was still “not just interested in the money,” he replied it is about creating millionaires and billionaires that look like you and I.” It would be those same words that once drew in employees like De La Torre.  “He might have the gift of gab and say all the right things but he treats the people closest to him awfully,” she said Jocelyn Martinez-Rosales is a Mexican-American from Belmont Cragin As an independent journalist she’s passionate about covering communities of color with a social justice lens and website in this browser for the next time I comment Δdocument.getElementById( "ak_js_1" ).setAttribute( "value" View More View More Volume 11 -

Under the universal kriging model the target variable at a given location si is given by the sum of a trend function, which is a linear combination of p + 1 auxiliary variables fj(si), multiplied by their respective beta coefficient, and a residual which shows spatial autocorrelation (17) (Eq. 1): The kriging weights λi are determined based on the semivariogram model fitted to minimize the prediction error (18) p(Z,s0) is estimated for the pixels covering the study area to yield maps of the predicted date of ASF notifications The predicted kriging time was represented by monthly interval isochrones using ArcGIS Pro 3.0.3 To quantify the ASF front-wave epidemic velocity, the surface of the prediction time resulting from the kriging analysis was included with the 3D Analyst toolbox of ArcGIS Pro as a vector of the map slope (magnitude), following the approach described by Moore et al. (14) The inverse of the slope surface corresponds to the front-wave velocity of ASF at each location within the study area The relationship between velocity (V) and slope (Sp) is given by V = s/t and Sp = rise/s where “s” is space and “t” is time rise was defined as the predicted monthly ASF occurrence time larger values of Sp mean slower velocity (1/Sp) and larger time interval “t” at similar distance result in slower V as well a higher slope value implies slower ASF diffusion while a larger vector of time (lower slope) leads to faster velocity of diffusion Space–time cluster aggregations of velocity of ASF spread were additionally explored using retrospective seasonal and normal models (SaTScan v10.0; 22) These models require the inclusion of case data and temporal information of each case Cluster selection was implemented based with varying temporal window of 3 to 6 months to capture seasonal differences Evaluation of cluster performance was conducted based on ranked relative risk (RR) log-likelihood ratio (LLR) values and p-values obtained from Monte Carlo hypothesis testing (9,999 permutations) The study area contains 9,693 grid cells of which 291 were selected for the universal kriging model, corresponding to 2,305 ASF wild boar notifications (Figure 1) Study area (centroid of each cell grid) depicted in light green overlaid is the kernel density of ASF wild boar notifications from January 2014 to January 2022 based on ADIS data shown in grey-blue shade Red dots are the 291 earliest monthly ASF notifications in wild boar extracted for each cell grid The empirical semivariogram shows strong spatial autocorrelation for notification dates and increasing large-scale semi-variance representing the spatial trend. Figure 2 shows the predicted kriging model fitted (γ) to the residual variogram and the linear combination γ + (β1 ∗ γX)2 (where γX is the variogram of the X coordinate) fitted to the not detrended variogram The one-leave-out cross-validation resulted in a bias of −0.43% and a mean ratio of squared residuals/kriging variance of 1.0031 Predicted kriging time surface of ASF infection in wild boar at 5-month intervals from January 2014 to January 2022 the green color spectrum represents the early phases of ASF prediction events over time while the red color spectrum represents the later months The front-wave velocity of ASF was obtained for 2,277 points with a median of 49.52 km/month (min.: 8.84; max.: 740.39) across the study area (Figure 3) the median velocity was highest for Estonia (75.60 km/month (min.: 21.41; max.: 740.39) n = 397) and lowest for Lithuania [36.52 km/month (min.: 8.84; max.: 344.29) followed by Poland [42.47 km/month (min.: 13.03; max.: 732.96) n = 1,179] and Latvia [53.95 km/month (min.: 11.98; max.: 697.05) Predicted ASF front wave velocity in wild boar (km/month) during the period from January 2014 to January 2022 while the red colors represent higher velocity of the predicted ASF front-wave velocity in wild boar the highest median ASF front-wave velocity in Estonia and Latvia were obtained in autumn [Estonia: 90.28 km/month (min.: 22.9 n = 190; Latvia: 61.11 km/month (min.: 11.98; max.: 329.78) the second highest median in Estonia happened in winter [75.6 km/month (min.: 21.53 while in Latvia it was in summer [59.79 km/month (min.: 16.45; max.: 697.05) the n was much smaller in Estonia in summer (n = 76) and in spring (n = 25) the number of points in Latvia in spring was only 19 the maximum velocities were reached in summer for both countries (640.21 km/month in Estonia and 697.05 km/month in Latvia) the number of predicted points was fewer than for the other countries (n = 258 in total) but the distribution is even among the seasons (although spring has the highest median front-wave velocity was achieved in summer (51.44 km/month) but the highest maximum was in autumn (344.23 km/month) the number of predicted points was much higher in winter (n = 688) than in the other seasons (between 113 and 198) the velocity median was homogeneous across seasons (between 35.45 and 48.34 km/month) although the maximum was reached in winter (732.96 km/month) The results by month shed similar conclusions there is a sufficient number of points to allow comparison for the months between August and January (>10% of the total predicted points per country) but there are fewer points predicted from February to July (<5%) May and June (<2%) to be considered in the comparative descriptive analysis The maximum velocities were reached in October and November in Estonia (706.36 and 740.39 km/month respectively) in Poland in February (732.96 km/month) and in Latvia in August (697.06 km/month) The highest median predicted velocity per year occurred in Estonia in 2015 (89.30 km/month) and in Latvia in 2014 (81.69 km/month) The highest maximum velocity in Estonia was predicted in 2016 (740.39 km/month) in Latvia in 2015 (697.05 km/month) in Poland in 2018 (732.96 km/month) and in 2014 in Lithuania (344.29 km/month) Similar results were obtained with SaTScan analysis showing one higher velocity temporal cluster from August to November (Mean = 93.64 SD = 111.56; p = 0.001) the majority of the predicted values (between 73 and 88%) fell in the maximum quality categories (5 and 6) of available habitat for wild boar making comparisons among the rest of the categories at risk of misinterpretation due to sampling bias The complete output from the descriptive analysis can be found as Supplementary material S1 The identification of a temporal cluster from August to November could indicate a potential period of increased transmission risk but should be interpreted with caution due to potential sampling bias The effect of habitat on wild boar movement was reviewed by Morelle et al. (31) The quality of habitat is influenced by the distribution and abundance of food resources and wild boar movements seem to increase particularly under high population density and low food availability Further investigation into the relationship between habitat characteristics and ASF transmission dynamics may provide valuable insights The velocity of ASF spread identified here allows us to explain the progress of the disease as an event The intensity of this event is not defined here other parameters such as the number of affected animals or serology data should be included For the purposes of policy and prevention practices the economic consequences could be considered similar leads to indirect losses derived from the “news effect” of the disease’s presence (for example in Belgium ASF was only notified in wild boar but domestic pig trade decreased in some sectors) the identification of a velocity front is a sufficient parameter to initiate the evaluation of consequences derived from the arrival of the virus It is important to recognize that our findings may be influenced by bias and uncertainty inherent to the kriging methodology. Kriging, a method that explicitly captures spatial correlation, operates under the assumption that values in close proximity tend to exhibit greater similarity. This allows for the inference of correlation at locations that have not been sampled, based on the points that have been sampled (20) Even though kriging offers certain benefits compared to TSA in terms of capturing spatial dependence and variation it is still susceptible to potential biases Factors such as the quality and quantity of input data which can occur in disease notifications in wild animals whose surveillance is subject to fluctuations can influence the accuracy of kriging predictions due to the possible delay between disease progression and notifications and the interaction between the grid size (which was chosen considering the spatial distribution of notifications) and potential jumps in the advancing front overestimations of the advancement speed may occur it is prudent to interpret our findings with caution recognizing the inherent uncertainties associated with the methodology employed Understanding the spatial and temporal dynamics of ASF front-wave velocity is crucial for designing effective surveillance and control strategies Tailoring interventions based on country-specific patterns and temporal clusters can enhance the efficiency of control measures and resource allocation The original contributions presented in the study are included in the article/Supplementary material further inquiries can be directed to the corresponding author The author(s) declare financial support was received for the research This research was funded by the Horizon 2020 Program of the European Union through the European Project H2020 “VACDIVA-A Safe DIVA vaccine for African Swine Fever control and eradication” project (grant agreement no The authors acknowledge the Ministry of Agriculture in Spain for facilitating ADIS data extraction and sharing The author(s) declared that they were an editorial board member of Frontiers This had no impact on the peer review process and the final decision The Supplementary material for this article can be found online at: https://www.frontiersin.org/articles/10.3389/fvets.2024.1353983/full#supplementary-material PubMed Abstract | Crossref Full Text | Google Scholar Google Scholar Google Scholar Google Scholar African swine fever in the North Caucasus region and the Russian Federation in years 2007–2012 Google Scholar Assessing the risk of African swine fever introduction into the European Union (EU) by wild boar Reproductive ratio for the local spread of African swine fever in wild boars in the Russian Federation African swine fever: a global view of the current challenge Update on the risk of introduction of African swine fever by wild boar into disease-free European Union countries Google Scholar Estimating front-wave velocity of infectious diseases: a simple PubMed Abstract | Crossref Full Text | Google Scholar Google Scholar Crossref Full Text | Google Scholar Crossref Full Text | Google Scholar Crossref Full Text | Google Scholar Crossref Full Text | Google Scholar Google Scholar A cartographic tool for managing African swine fever in Eurasia: mapping wild boar distribution based on the quality of available habitats Crossref Full Text | Google Scholar African swine fever: lessons to learn from past eradication experiences Eight years of African swine fever in the Baltic States: epidemiological reflections Seasonal occurrence of African swine fever in wild boar and domestic pigs in EU member states Natural inactivation of African swine fever virus in tissues: influence of temperature and environmental conditions on virus survival Behaviour of free ranging wild boar towards their dead fellows: potential implications for the transmission of African swine fever The potential role of scavengers in spreading African swine fever among wild boar Dynamics of the African swine fever spread in Poland Citation: Martínez Avilés M de la Torre A and Iglesias I (2024) Spatial and temporal analysis of African swine fever front-wave velocity in wild boar: implications for surveillance and control strategies Received: 11 December 2023; Accepted: 13 March 2024; Published: 25 March 2024 Copyright © 2024 Martínez Avilés, Montes, Sacristán, de la Torre and Iglesias.

Volume 15 - 2021 | https://doi.org/10.3389/fnana.2021.787913 The prosomeric model was postulated jointly by L Rubenstein in 1993 and has been developed since by means of minor changes and a major update in 2012 This article explains the progressive academic and scientific antecedents leading LP to this collaboration and its subsequent developments Other antecedents due to earlier neuroembryologists that also proposed neuromeric brain models since the late 19th century as well as those who defended the alternative columnar model The circumstances that apparently caused the differential success of the neuromeric models in the recent neurobiological field are also explored The present special number of BBEV titled ‘Beyond the prosomeric brain model’ offers me the opportunity to present some notes explaining how I came to be involved in the birth of this model I would not have space for reviewing relevant literature in too much detail or even to mention all our publications using this brain model I will rather highlight the major circumstances that Although the account deals initially largely with my own experiences the active participation of various colleagues and collaborators increases in importance afterward strongly influenced by the published work of earlier scientists which also need to be mentioned and placed in context I think that this story began when I first found neuromeric ideas at the school of medicine of Granada (Spain) I was photocopying selections from the Journal of Comparative Neurology During the last year of my medical studies at the University of Granada (term 1970–1971), I started to attend the embryological laboratory of a newly incorporated professor of anatomy, Génis-Gálvez (1924-2003; see biographical notes on Génis-Gálvez in Velasco-Morgado, 2014) He had transferred from Salamanca to Granada in 1968 I had passed my anatomy and embryology subjects with a different professor After 3 years of preclinical subjects and two 2 of clinical studies I had decided to finish my sixth and final year of medicine studies for which I had found I had little vocation I had chosen instead a research career in neurobiology Understanding the mind had been my major interest since adolescence when I first tried to explain to myself volatile adolescent amorous reactions observed within my school class (boys and girls half and half) I was detoured from my consequent strong interest in psychology (then only approached in Spain as a third year subject in medical studies) by the dogmatic verbiage offered by my psychology and psychiatry professors in Granada (third and fourth terms) I had already decided to attempt a formation in neurobiological research After short visits of the physiology and histology/pathology departments (where I found no neurobiological research was done) a professor suggested to try the ‘new’ anatomy professor J The idea was to occupy myself with brain development during the last year of medicine and then apply for entrance at a leading neurophysiology laboratory in Madrid Professor Génis-Gálvez was very receptive He explained to me mainly the possibilities to do experimental embryology in his lab he showed me in the lab how one opens an incubated egg and finds inside the chick embryo this morphological approach with experimental possibilities relegated to the far background my psychological and physiological interests on the mind although they persisted up to the present as a reading hobby that psychology apparently had nothing to offer me at that time point It seemed that there was a lot of preliminary work to be done yet on basic brain structure before higher mental properties could be properly addressed I estimated that the status of neurophysiology probably was not much more advanced in this sense than that of psychology came out of the interview with a handful of reprints on brain development to read and a very vague idea that I wanted to study brain structure hoping to develop more specific plans as I advanced I read immediately the articles Génis-Galvez had given me and entered his office again 20 min later to ask him for more My tutor worked specifically on the developing eye (he was a non-practicing ophthalmologist originally) and thus could not teach me much about the brain proper beyond what one learned then in medical neuroanatomy he was happy to have in the lab somebody who would try to develop a line of work in central aspects of the visual system He helped me by providing guiding literature (he had a good collection of basic books and reprints obtained during his stays in the States) and placed at my disposal a small laboratory I started to work away with maximal dedication and dropped altogether attending my last term classes (I just crammed the subjects 3–4 days before the exams) My intense readings during that first year represented an introduction to modern biology although without systematic botany or zoology complementing partially my standard medical formation in a direction helpful for research I cannot say that I learned much about the brain except what I saw personally at the microscope The theory of evolution apparently was not studied at all in Granada at the time I learned of its major conclusions only years later in books I thus had no idea of comparative neuroanatomy or neuroembryology I simply extrapolated what little I knew from the human brain to the chicken brain I assumed that birds moved their eyes with comparable muscles and nerves as Ramón y Cajal seemed to imply in his treatise He was a pragmatic evolutionist and comparative morphologist accepting a priori that vertebrate brains were comparable but he never discussed theoretical issues such as the concept of homology or Haeckel’s and Baer’s contrasting ideas on developmental recapitulation of evolutive change there was no textbook on comparative neuroanatomy available nor an avian brain atlas at least as regards the visual system and oculomotor mechanisms equivalent structures could be expected in humans (mammals) and birds but my initial rate of advance in learning to recognize chicken brain structures was extremely slow The brain I had in front of me at the microscope was a large complex of structures I could not identify with only a small area illuminated by understanding at the oculomotor nuclei I needed many years of solitary toiling with reprints or photocopies and the microscope before I slowly expanded my neuroanatomic knowledge to neighboring areas helped by avid exploration of literature on the brain of birds compared to those of other vertebrates I expanded to the whole brain thanks to the prosomeric model which allows prediction of structures you are going to see The columnar model defended by Herrick (1910; 1933; 1948) and Kuhlenbeck (1927, 1973) was then absolutely prevalent and was implicitly assumed by all neuroanatomy book authors All of us (experts and beginners alike) used that model often without being aware of its existence or its fundaments (more on this model below) It is like breathing without knowing that air exists Over the summer of 1971, after finishing my medical studies, I returned to my parental home in Tenerife (Canary Islands) and married my girlfriend from preuniversitary studies and subsequent lab collaborator in Granada Margaret Martínez-de-la-Torre. After our honeymoon, I read the well-illustrated textbook of Embryology which had been published by Génis-Gálvez (1970) This stimulating book confirmed my interest in embryology as well as in its experimental possibilities and I started to work on my doctoral thesis project (officially tutored by Génis-Gálvez I also began to teach some anatomy and dissection for medical students as a part-time teaching auxiliary although it was clear to all of us that a research career in the Spain of Franco was highly risky my tutor applied for a transfer closer to his birthplace in Cadix to a position at the anatomy department in the University of Sevilla (Granada is the largest of them; its university also encompassed then the isolated medical school at Cadix) Génis-Gálvez obtained the Sevilla position and in his plans for transferring in 1972 the whole lab (including Margaret and me) he got funding from the Granada faculty dean to photocopy any departmental journal article that was of interest to us The job to decide which articles were to be photocopied in the Journal of Comparative Neurology fell to me (we had an ample collection) I thus spent hours perusing systematically through hundreds of JCN articles since I really knew little of such contents and nothing at all about the possible fame of the authors If I found minimally interesting the title not a result of understanding the need for such a schema but of just noting a new possibility to visualize synthetically brain structure It was the sort of spine-tingling emotion produced otherwise by sublime musical passages which one does not understand technically The neuromeric article thus passed to the collection we brought to Sevilla subsequent calm reading did not show how to relate those interesting theoretical ideas to my daily work in the lab on the oculomotor nuclei and the interstitial nucleus of Cajal (the subject of my thesis) The needed context of being aware of alternative brain models and differential explanatory capabilities was wholly absent without forgetting the impression it had made on me and only returned to it several years later when its implicit content started to become meaningful Figure 1. Neuromeric model of Bergquist and Källén (1954). Note that neuromeres I–VII are superposed by transversal bands 1–7. Also, neuromeres I–II imply an ending of the forebrain axis in the telencephalon (a columnar notion departing from the axial concept of His). In subsequent publications, Bergquist and Källèn corrected this error (see Figure 6) noting that neither the telencephalon nor the eye vesicles represent true neuromeres as well as my first experience with mammalian embryos A major neurohistological figure I met at the INSERM U106 was Constantino Sotelo an expatriated terminal member of Cajal’s school (direct student of Fernando de Castro one of Cajal’s younger collaborators) He was then famed as one of the major experts in brain electron microscopy and also was interested at the time in neuroembryological questions He recommended trying Golgi impregnation methods on the oculomotor migration and particularly the variant of Stensaas (with glutaraldehyde substituting osmium tetroxide in the fixative solution) which he thought worked better in embryos than the standard rapid Golgi procedure (osmium fix) started a collection of Golgi-Stensaas impregnated rat embryos which I brought with me to Sevilla at the end of the stay I also tried out the Stensaas procedure on chick embryos and found it worked much better than in rats (unless the exceptional success was due to the water of Sevilla) I concentrated on the increasing collection of chicken Golgi preparations Apart from my teaching duties (several hours daily) I generally processed one embryo per week (fixation and mounting the thick celloidin sections strictly ordered on slides and finally looking at them at the microscope) Beautifully impregnated developing neurons and many other sorts of cells appeared filled up by the reddish-brown silver chromate precipitate apart from the desired neuronal and glial cells became an autodidact distant pupil of the school of Cajal Figure 2. Selected neuromeric schemata from the work of Tello (1923) showing sagittal sections through chick embryo brains at two different stages wherein diverse reduced-silver-stained tracts clearly relate to neuromeric bulges the growing optic tract is represented as a longitudinal tract relative to the diencephalic neuromeres The school of Cajal had practically disappeared in the post-civil-war period and only the publications remained who was active in his youth in comparative brain studies and Tello (the only pupil of Cajal doing neuroembryology) died in 1958 having been expelled from the direction of the Cajal Institute in 1936 as a collateral result of the Spanish civil war I received some technical advice and psychological support from Constantino Sotelo since he was the first scientist of excellence I met Sotelo also supported my ulterior first publication on the chick neuromeric model (see below) The neuromeric papers of Tello were the second place where I encountered neuromeric concepts although at this point I was concentrated on cellular differentiation details of the tectal neurons and was not attending at all to the issue of neuromeres This gradient allows tentative differentiation stages to be checked rostralwards (where more advanced cells can be seen) and caudalwards (where less advanced cells are found) as long as the preparations are as homogeneously Golgi-impregnated as mine were This project took most of my research time during my last years in Sevilla (up to the end of the 1975/1976 term I left aside momentarily the oculomotor migration problem the tectal work advanced at a slower pace into later stages of development (9–12 days of incubation) with the help of a doctoral student and thereafter also dear friend We jointly discovered an additional more retarded Type III sort of tectal cell prototype She read her thesis on the chick tectum in 1978 when I was already in Cadix after spending a year in Badajoz most of the late tectal data remained unpublished I unexpectedly was offered a contract as full professor and director of the anatomy department at the University of Extremadura (at Badajoz although this implied a transient rupture with Génis-Gálvez my Golgi collection had to remain in Sevilla started a new laboratory and a new Golgi collection in Badajoz where I was wholly on my own as regards research and the sort of neuroanatomy I taught I prepared there under singular conditions (no funding) the manuscript on early differentiation of tectal cell types A comparable result has not been produced yet in anamniotes or mammals although some of the published Golgi data in fish and mammals show neuronal examples comparable to our cell types and the optic tectum is known to be highly conservative in its connections some added elements (perhaps novel cell types) might occur given what we know of divergent superficial tectal stratification and the massive cellular development of the periaqueductal gray compared to that of sauropsids and anamniotes The periaqueductal gray is often figured as if it was independent from the superior and inferior colliculi but its cells underlying the colliculi arise late from the same progenitor domains I think the Puelles and Bendala (1978) tectal report was my first important scientific publication (7 years after I started) it is the most complex histogenetic analysis ever done with the Golgi method I am proud that it was performed without other guidance than the rationale exemplified previously by Ramón y Cajal This study taught me what sorts of differentiative and migratory complexities may be found in the histogenesis of a distinctly delimited progenitor area over time The three distinct postmitotic neuron prototypes diversifying gradually into the various final neuronal forms strongly suggested that the genetic profile present at cell birth was highly important in determining the fundamental behavior of the cell whereas the changing surroundings over time probably exert an epigenetic mechanistic modulatory role on the emerging phenotypes Another paper I submitted jointly to Neuroscience while in Badajoz dealt on the earliest Golgi-impregnated shapes of developing tectal oligodendrocytes (Puelles, 1978a; Figure 3B) It appeared slightly before the tectal one because it was accepted without any changes; this is the only time this happened to me I think that these results still represent the only published visualization so far of young postmitotic oligodendrocytes in the process of enveloping axons with their lamellipodial processes that I obtained part of the multi-volume comparative treatise of Kuhlenbeck (published by Karger between 1967 and 1978; ‘The Central Nervous System of Vertebrates’) which I also studied with enormous interest with whom I have had many mental discussions over the years but he interpreted them as coursing oblique to his axis The hp1 and hp2 domains are the two hypothalamo-telencephalic prosomeres postulated by us in the updated prosomeric model The two cross-sections at left correspond to the section levels marked in the map as 44 and 41 They illustrate the differential histogenetic patterns and the abrupt boundaries corresponding to the interneuromeric borders where Rendahl did not postulate neuromeres He only represented the longitudinal sulcus limitans at p1 and p2 We extend this landmark through p3 and the hypothalamus as well ending under the optic chiasma (blue line) Figure 6. Comparison of the neuromeric models of Bergquist and Källén (1954) (A3) and Rendahl (1924) (C2) with our own chick model, extracted from Puelles et al. (1987a; B4) The precociously populated basal plate neuromeric modules are emphasized The B&K schemata show in (A1) their neuromeres (later corrected) and in (A2) their transversal bands which we take as corresponding most realistically with our neuromeres Our schemata include early stages in the emergence of the neuromeric pattern in the schemata (B1–B3) The Rendahl schemata (C1,C2) reveal that this author postulated the telencephalon as a prosomere I lying rostral to the diencephalon thus showing the influence of the columnar axis it is clearly observed that the three sets of schemata are basically comparable in many aspects I had checked in Badajoz whether the three tectal neuron prototypes were generally present in other parts of the brain as was already suggested by existing Cajal data on the spinal cord substantiating the conclusion that the brain wall was apparently divided into multiple areal progenitor units with differential histogenetic patterns and characteristic cell types (a concept we later used in the prosomeric model Given the success of the Golgi study of the optic tectum I chose to begin in Cadix a Golgi study of neuronal differentiation sequences in the developing chicken diencephalic visual centers The latter were scattered over the hypothalamus and pretectum according to the columnar model I was helped in this project by a new thesis pupil For the diencephalon, we initially applied the widely prevalent columnar model to the analysis of our Golgi data. We followed the columnar embryologic Nissl studies on chick diencephalic development done by Kuhlenbeck (reviewed in Kuhlenbeck, 1973) According to the interpretation of this author were cellularly homogeneous longitudinal masses of neurons displaying similar functional properties along their length (somatic versus visceral; motor versus sensory; somatosensory Since all postulated diencephalic columns clearly received specific retinal input via the optic tract (some of them several distinct inputs) we soon noted that it was absolutely unclear how viscero/somatic or sensitive/motor sorts of signals were distinguished from visual signals in the columnar diencephalon (i.e. apart of entering its visual sensory input through the postulated diencephalic floor and basal plate equivalent region at the hypothalamic chiasma a very odd pattern absent in the hindbrain) the higher resolutive power of the Golgi-Stensaas method (showing differential details of the neuronal axons and dendrites) immediately refuted this assumption Unexpected clear-cut boundaries separated distinct intracolumnar fields having different neuron types crossing obliquely the theoretically homogeneous columns and defining distinct non-columnar blocks of neurons in terms of observable early differentiation sequences Instead of advancing nicely along a gradient the diencephalic Golgi image was a mess of contradictory data we simply could not make meaningful using the Herrick/Kuhlenbeck columnar model started doubting this model and looking around for some alternative model that would explain what we saw Colleagues familiar with my subsequent work think that I moved in the 1990s into neuromeres due to evidence coming from gene expression patterns I first learned about neuromeres some 20 years before but only started to think they might be important for my research due to the problems I had with the interpretation of Golgi impregnations in the chick diencephalon in the late 1970s at which moment I was the expert in neuromeres of the new generation whom I met in his retirement during a private weekend visit in 2002 told me that he had never talked with Holmgren personally and that the members of the ‘school’ hardly interacted or met with each other Even the closer collaborative research relationships of Källén with Bergquist were darkened by the repulse of Källén of the Nazi orientation of Bergquist (they never were friends His former Nazi connection had reduced Bergquist to working after the war as a public school teacher He was a sort of visiting scientist in Tornblad Embryological institute directed by Källén (a casual conversation of Bergquist with Källén’s father He could use there the comparative collection of embryonic preparations of Ivar Broman we hesitated about publishing this conclusion since I feared that an attack on the solid columnar establishment based on ‘mere’ Golgi data in the era of experimental neuroanatomic studies and immunocytochemistry was going to be exceedingly difficult and probably unsuccessful I started preparing instead a photographic documentation of the neuromeric pattern of the developing avian visual centers using Nissl data because I was continually distracted by other preoccupations such as obtaining tenure (in Cadix) and later two academic jobs I accepted in series in Murcia (vice dean of the medical school and later vicerrector of research) an old friend from my German-school days in Tenerife lives in Stockholm and he obtained for me photocopies of all relevant Swedish documents at the Karolinska Institute (all the works by Holmgren (4) Early students of neuromeres did not attempt to investigate their possible modular functional properties in the adult brain These aspects are increasingly being studied today (neuromeric analysis of modular aspects of serotonergic raphe nuclei and still center their attention instead on the connectivity and circuit functions apparently performed by dedicated parts of the columns There is to this day no columnar theory explaining how an embryonic column diversifies into a collection of distinct nuclei the prosomeric model has incorporated dorsoventral and anteroposterior patterning and regionalization effects leading to molecular definition of the component progenitor areas that produce specific cell types or nuclei The columnar model is incompatible with these experimentally demonstrated patterning effects because its arbitrary length axis ending in the telencephalon prohibits it (the implicit meanings of the columnar descriptive terms dorsal and posterior are inconsistent with what we now know of brain patterning) The speculative columnar structure of the forebrain has nevertheless become dogmatically established in the literature after a century as a conventional truth or fact No expert acknowledges that there is an underlying theoretically fallible columnar model dating from 1910 that is responsible of a major scientific impasse Criticisms of the columnar model of Herrick are labeled as unjust attacks on a ‘straw man’ (this is personal experience) since modern neurobiologists no longer are conscious of following the columnar model This factual character of the columnar model in practice was the barrier I had in front once I realized the obsolescence of this model and the need to substitute in its place a neuromeric brain model corrected from earlier errors throughout neuroscience I needed a modern technique which could be used to reverse the status quo what I obviously really needed were gene expression patterns and the experimental analysis of neural patterning These new research instruments could not even be imagined in the late 1970s where no molecular research was performed by anatomists; I was literally thought to be out of my mind when I expressed to colleagues interest in molecular genetics for progress in embryology and anatomy A division of the heads through the midline helped the mapping of the stained neurons through the unstained ventricular zone in the translucent head halves Soon I perfected the method by dissecting after the reaction the skin and meninges away under an operating microscope using sharp tungsten needles Frozen or cryostat sections habitually used for histochemistry did not allow an overview unless graphic reconstruction was attempted a method hampered by the usually incomplete cryostat section series Our study of AChE wholemounts accordingly increasingly concentrated most of my efforts during the last period in Cadix (1978 in which endeavor I was helped considerably by a new collaborator and thesis pupil The same study still continued for several years more in Murcia before we first attempted publication in 1986 We proposed the introduction in the neuroanatomic terminology of the term pre-isthmus alluding to this novel midbrain anatomic domain just in front of the isthmus proper and caudal to the inferior colliculus At the beginning of the 1980–1981 term (September) in whose medical school and anatomy department Margaret and I worked thereafter for 40 years The laboratory had to be organized from zero No silver or Golgi method worked because double distilled water contained too much organic material so that silver and chromium salts systematically precipitated This was the reason why I ceased to use those techniques and concentrated on the AChE material We had to install a system for de-ionized water which took some time and the arrival of national funding We first obtained in 1981 a grant from the ministerial central funding agency in Madrid (I had not applied before I do not know exactly why: perhaps no public grants were available during my previous formative years or at least they were not known to me; Génis-Gálvez had been funded habitually by a private foundation) we continued having sufficient national grant support on a 3-year renovation basis up to my retirement in 2018 (the last 5–6 years we had an extremely hard to get Excellency grant—only two were given per year in Spain) We also had extra help in parallel from several European projects we also obtained some significant funding from the local regional government in Murcia (Séneca Foundation) All this funding helped us to expand and modernize the lab to international standards and we established infrastructure and know-how for molecular biology procedures as well as automatized scanning of our slides we studied neurogenetic patterns in the chick brain using thymidine autoradiography This accompanied our whole-mount AChE visualization of differentiating young neurons Parts of the autoradiographic data on the isthmus and diencephalon (thalamus) were published where an incipient but remarkably incomplete brain Bauplan was found it had to be capable of application in all vertebrates and its early forms might be already detectable in cephalochordates (this was indeed what we found in the cited Amphioxus paper with unsuspected novel collateral aspects) we worked much (demonstrating the wide usefulness of the prosomeric model in such studies as noted also by other laboratories that incorporated to the quest) and obtained large amounts of histological material of various types It was all very useful for advancing my evolutionary ideas although we did not publish large parts of it since we first had to introduce the neuromeric model into the field (we only achieved this by publications in 1987 and 1993) and then we had to lift our lab to the capacity to perform molecular mapping studies The first published gene pattern I noticed that showed a neuromeric pattern appeared in the report of Gaunt et al. (1986) on Hox1.5 expression in mouse embryonic hindbrain The authors showed that Hox1.5 expression had a distinct rostral limit at a constriction of the hindbrain neural wall They apparently did not realize (as I immediately did) that this constriction was an interrhombomeric boundary I noted the enormous relevance of that sort of data for our project since all interneuromeric and intraneuromeric boundaries now probably could be explained and visualized as patterned gene expressions I visited the laboratories of friends in Paris (Marion Wassef at L’ École Normale) and Madrid (Angela Nieto at the Cajal Institute) in order to learn personally in situ hybridization procedures and associated molecular concepts and techniques we looked preferentially at intrinsic patterns of neurons inside the brain wall it represented altogether a stronger basis for our attempt to attack the columnar establishment with our revamped neuromeric model for the forthcoming morphologic interpretation of relevant gene expression data in the early 1990s The Puelles et al. (1987a) manuscript on AChE data in a neuromeric pattern was first submitted in 1986 after first showing it to Sotelo in Paris who passed it on with a favorable comment to S the editor-in-chief of the Journal of Comparative Neurology The paper evaded criticizing the columnar model; it just showed abundant photographs of what we had found and stated that the patterns were clearly consistent with the neuromeric models of the past Palay sent back reviews suggesting that perhaps because we worked in a Spanish provincial city we were not aware that this subject of neuromeres had been discarded many years before and that we should examine modern literature in university libraries in Madrid or Barcelona The rather supercilious reviewers apparently thought that we somehow were using ideas and literature citations left behind by our grandfathers Palay nevertheless asked us to send back a shortened and appropriately modified version of the text I highlighted the point that none of the reviewers had found anything to criticize or reinterpret about our photographic data so that we did not see in which sense we should change our interpretation Our results seemed indeed to revitalize old forgotten neuromeric notions but the age of such notions and their conventionally disregarded status were not our responsibility We just stood on a novel sort of evidence—unobjectionable wholemount AChE reactions—that strongly agreed with these old ideas obviously disagreeing with the contrary columnar ideas a la mode I made known to Palay the vast preliminary analysis of relevant literature I had performed over the previous 10 years (including not only everything in English but also in other important scientific languages) I included a synopsis of the journal and book material obtained from the libraries of the Karolinska Institute in Stockholm the Max Planck Institute in Göttingen and the second version was accepted without any further discussion and he probably acted against the opinion of the reviewers in agreement with the important supporting position of Sotelo in our first decade working in Murcia (1981 to 1991) three of them dealing with neuromeric subjects Margaret and I traveled to La Jolla (California) to work 1 month on fish and amphibian brains with the comparative neuroanatomist Glenn R Northcutt at the Scripps Institute of Oceanography using his own material (previously unknown to us) evidence in favor of the neuromeric brain model We first tried some Ambystoma tigrinum (salamander) brain specimens cut sagittally, which we immunoreacted with calretinin (note that Ambystoma was the amphibian species most studied by Herrick in his columnar studies and also the object of his recapitulative book “The Brain of the Tiger Salamander,” Herrick, 1948) I thought that the calretinin—CR—marker (used before by us in chick and lizard embryos) might be favorable for identifying a positive dorsal thalamus against the CR-negative ventral thalamus and pretectum domains (these represent the three diencephalic neuromeres in the alar plate) Such differential staining should also show that the corresponding limits are transversal (i.e. contrary to columnar expectations postulating at least one of them—the interthalamic zona limitans limit—to be longitudinal) the yearly meeting of the American Society for Neuroscience was held nearby in San Diego and I attended it as an observer (this was my first time at the SfN) I heard an oral intervention by a young researcher from San Francisco—John R Rubenstein—who presented the diencephalic and telencephalic expression pattern of a newly discovered gene then called Tess1 (for his daughter Tess; this was his first output in gene mapping) This gene subsequently was reclassified as Dlx2 (a member of the important Dlx family functionally involved in the generation of forebrain GABAergic neurons among other properties; distalless refers to lack of terminal leg parts in Dlx-mutant Drosophila) Rubenstein presented at the SfN a columnar interpretation of the diencephalic expression pattern of Dlx2 which seemed to me problematic in several aspects I thought that a more significant interpretation was possible using the neuromeric model Somebody he had recently consulted had given it to him as a possibility to explore alternative interpretations he needed its application to mouse embryos I assured him that this posed no difficulties Figure 7. First version of the prosomeric model, from Bulfone et al. (1993). The genes mapped are color-coded. Note that, at variance with the bipartite chick hypothalamus of Puelles et al. (1987a; see Figure 6B4) we postulated three hypothalamic prosomeres p4–p6 for the mouse This was an error that we corrected subsequently Figure 10. Comparison of the prosomeric models conceived by Puelles and Rubenstein (2003) (A) and Puelles et al. (2012a) (B) to visualize the significant changes introduced in the updated version, which were explained in detail in Puelles and Rubenstein (2015) Equally important for the progress of the prosomeric model were the experimental embryologic contributions of my pupil Salvador Martínez on the analysis of the isthmic and mid-diencephalic secondary organizers as well as on clone-isolating properties of interrhombomeric and forebrain limits (B) Schema representing the whole set of prosomeric units in the adult brain (the cerebellum belongs to r0—the vermis—and r1—the hemispheres) Note the large evaginated telencephalic development corresponding to hp1 (red) while the rostral end of the brain corresponds to the acroterminal domain within hp2 (orange) The bipartite hypothalamus is divided into peduncular hypothalamus (PHy) within hp1 and terminal hypothalamus (THy) within hp2 The axis of the brain clearly bends ventrally at the cephalic flexure where a number of interneuromeric boundaries converge pialwards and also shows a less marked dorsal bending at pontine levels causing there also some convergence of neuromeric boundaries at the ventricular surface apart what was already mentioned in the text but I believe there are many possibilities implicit in the modular serial arrangement of neuromeric components as well as in the dorsoventral microzonal structural aspects I expect a revolution in neurophysiology and a step forward in cognitive studies the model has been already extraordinarily successful in the fields of developmental neurobiology (including particularly fate-mapping and patterning studies) and comparative evo-devo studies It is difficult at the present stage to envisage what sort of neural model could be still better in order to improve studies on the nervous system although time and the nature of things will probably modify sooner or later this impression An eye needs to stay open in this direction to ensure that the prosomeric model does not become a centenary dogma The validity of a model is limited by its utility and the credibility of its assumptions The support of the Spanish Ministry of Economy and Competitiveness grant

Eng and Antonia Aguilar Cole [courtesy photo]With grit and dedication the Villa Parke boxing program’s Golden Girls have punched and jabbed their way into the Golden Gloves State Championship this weekend Asia Eng and Antonia Aguilar Cole will be fighting on April 1 and 2 in Concord If they win the upcoming state championship they will advance to the Golden Gloves nationals tournament to be held in Pennsylvania from May 8-13 and could potentially earn a spot at the Olympic qualifiers The proud boxing instructor of the quartet head boxing instructor at the Villa Parke Boxing Gym said it is their dedication that sets these women apart from others “They have put so much work and dedication into their workouts and into the sport,” he said who will be fighting at the 178-pound division has been with the Villa Parke boxing program since she was 11 “She lives and breathes boxing for all her life That’s her,” De La Torre said of Martinez having been listed as a finalist for the Olympic trials in the past Martinez said she picked boxing as her sport because she experienced bullying when she was young She said the sport strengthened her not only mentally but as well as physically head boxing instructor at the Villa Parke Boxing Gym [Eddie Rivera/Pasadena Now]“What I love about this sport is that you’re able to express yourself through the sport You’re able to leave it all in the ring but it’s about being a smarter fighter being able to show and display your hard work “This sport has taught me so much discipline It has taught me that I have to also prepare for life I have to also make sure that I was able to get an education through the sport of boxing It just helps you become a better person.” Martinez’s goal is to make it to the Olympic trials again and get a gold medal “I wasn’t able to get a gold medal a few years back but now I want to try it again and test myself again “She tries really hard to keep up with the team,” he said “She doesn’t have a lot of experience Machabie will be fighting in the Golden Gloves State finals at 146 pounds She started boxing in 2018 but it was only over summer last year that she got into competitive boxing and truly dedicated herself to the sport There’s so many layers to the sport that it really challenges you as an athlete “And just like the intricacies of the art to really exercise discipline see how far you can progress in something and learn the footwork like the different striking techniques and build your endurance.” Machabie admitted being in male-dominated sports is hard at the beginning because as a female no one will take you seriously until you have proven yourself you need to be a competitor or no one’s going to pick you up just because you’re a woman Then everybody will skip on you to play a five-on-five game but then when you prove yourself that you’re a competitor and you can score And I feel like it’s the same in boxing.” “You prove that you love the craft and you can compete and then more men are likely to spar with you It’s kind of a ceiling because you are a woman but we’re trying to break through that.” The most important thing she learned from the sport is the importance of consistency and teachability Machabie hopes to win on Sunday and make it to the Olympic team “I think that’s the first goal — to see if I can try to make the Olympic team It’s going to take a lot of training.” Eng has been in the sport for about 10 years now but she has been with Villa Parke boxing program only for four years Described by De La Torre as a “very strong” and “seasoned” fighter will be fighting the State finals at 139 pounds boxing for Eng is a “violent dance.” so it’s really important for my mental [health] “I feel like I give a little piece of myself in the ring and that person also gives a little piece of themselves in the ring and we just share like this very unique experience There’s a lot of reasons why I like boxing and those are just a handful.” Eng finds it satisfying to constantly grow in the sport so I know I’m a [stronger] person this year than I was last year.” She has also learned that while boxing is a one man sport when inside the ring winning is impossible without the community “I couldn’t be there without my coach or my stablemates I also can’t do it without the people who helped me in the gym.” “I’d be really nice if I could learn how to give back to teach it at the gym I would like to become a referee or judge or just see where the sport can carry me.” Described by De La Torre as a committed and hardworking boxer Cole will be fighting in the 125-pound flyweight division “I really love the sport,” said Cole who started boxing when she was in college People say boxing is the loneliest sport because it’s you in that ring But what I found is that I have my coach in the corner and it’s really been a journey of finding yourself and finding your capabilities.” Cole has also tried other sports including basketball and weightlifting “For me [boxing] has become a way of life So it has really become the foundation for how I live my life and the way I train and the things I interact with.” just fight the good fight and have fun,” Cole said when asked about her goal De La Torre said the four are now undergoing rigorous training in preparation for their upcoming fight The four go to the gym two to three times a day for workouts and training “Three times out of the week we’re out sparring So we go to different gyms and we spar with other girls or other males,” De La Torre added “They can either be male or female just to keep them

Hypophosphatasia (HPP) is an inborn metabolic error caused by mutations in the ALPL gene encoding tissue non-specific alkaline phosphatase (TNSALP) and leading to decreased alkaline phosphatase (ALP) activity. Although the main characteristic of this disease is bone involvement, it presents a great genetic and clinical variability, which makes it a systemic disease. The two new mutations have been classified as pathogenic. At the clinical level, this study suggests that both mutations not only lead to pathognomonic symptoms of the disease, but may also play a role at the systemic level. Volume 14 - 2023 | https://doi.org/10.3389/fendo.2023.1320516 Introduction: Hypophosphatasia (HPP) is an inborn metabolic error caused by mutations in the ALPL gene encoding tissue non-specific alkaline phosphatase (TNSALP) and leading to decreased alkaline phosphatase (ALP) activity Although the main characteristic of this disease is bone involvement it presents a great genetic and clinical variability Methods: Patients were recruited based on biochemical assessments Diagnosis was made by measuring serum ALP and pyridoxal 5-phosphate levels and finally by Sanger sequencing of the ALPL gene from peripheral blood mononuclear cells Characterization of the new variants was performed by transfection of the variants into HEK293T cells where ALP activity and cellular localization were measured by flow cytometry The dominant negative effect was analyzed by co-transfection of each variant with the wild-type gene measuring ALP activity and analyzing cellular localization by flow cytometry Results: Two previously undescribed variants were found in the ALPL gene: leucine 6 to serine missense mutation (c.17T>C L6S) affecting the signal peptide and threonine 167 deletion (c.498_500delCAC T167del) affecting the vicinity of the active site These mutations lead mainly to non-pathognomonic symptoms of HPP Structural prediction and modeling tools indicated the affected residues as critical residues with important roles in protein structure and function In vitro results demonstrated low TNSALP activity and a dominant negative effect in both mutations The results of the characterization of these variants suggest that the pleiotropic role of TNSALP could be involved in the systemic effects observed in these patients highlighting digestive and autoimmune disorders associated with TNSALP dysfunction Conclusions: The two new mutations have been classified as pathogenic this study suggests that both mutations not only lead to pathognomonic symptoms of the disease but may also play a role at the systemic level Figure 1 Main functions of TNSALP in the body (A) shows the correct function of TNASLP: PPi is hydrolyzed to Pi for subsequent conversion to hidroxyhapatite crystals (HAP) in microvesicles via the action of TNSALP PLP is hydrolyzed to PL by TNSALP to cross the blood-brain barrier where it is subsequently reconstituted into PLP and leads to the formation of neurotransmitters (B) shows the molecular effects related to defective TNSALP: Loss of function in TNSALP produces an accumulation of its substrates PPi inhibits bone mineralization while PLP cannot cross the blood-brain barrier decreasing the production of neurotransmitters (C) shows clinical manifestations related to defective TNSALP: The accumulation of PPi alters calcium/phosphate homeostasis while increased levels of PLP lead to a decrease in B6 supply at the neurological level the autoimmune and digestive implications have not been explored to date although there appears to be a relationship between low in vitro TNSALP levels and disease severity there are other variables that influence the development of clinical manifestations in affected patients two previously undescribed mutations are presented in two patients recently diagnosed with childhood-onset HPP with no familial relationship and with completely different clinical features The aim is to characterize each of the new mutations at the genetic structural and functional levels to establish a relationship with the clinical features Clinical characteristics and biochemical parameters have been useful in establishing a correct diagnosis of the rest of the relatives it is worth emphasizing the importance of establishing a geno-phenotypic relationship for each newly identified mutation to provide more information and better patient management Two fifteen-year-old male patients were evaluated in the Endocrinology Unit of the University Hospital Clínico San Cecilio of Granada following the algorithm developed by García-Fontana et al. (4). Neither of the two patients took vitamin B6 supplements. Patients with secondary causes of hypophosphatasemia such as malnutrition, magnesium and zinc deficiencies, haemochromatosis or certain therapies, were excluded (2, 27) Two venous blood samples were taken from each patient at the Clinical Analysis Unit of the University Hospital Clínico San Cecilio; one was for ALP and PLP determinations and the other one was used for ALPL gene sequencing Written informed consent was obtained from their legal guardians and an individualized and personal interview was conducted on potentially related HPP symptoms This study was approved by the ethics committee of Granada following the principles of the World Medical Association Declaration of Helsinki (Project ID: 0777-M1-20 Research Ethics Committee of Granada Center [(CEI-Granada) on 8 May 2019] Plasma PLP levels were measured by high-pressure liquid chromatography (HPLC) at the Clinical Unit of the University Hospital Niño Jesús (Madrid) Chromatographic determination was determined using an isocratic HPLC system an emission laser at 320 nm and a fluorescence detector was used Reference values (3.6-18 ng/mL) were established by University Hospital Niño Jesús and for fifteen-year-old males a copy variant number study was performed by multiple ligation probe amplification (MLPA) (MRCHolland) and the results were analyzed using the SeqPilot program (JSI Medical System) The Biomedical Diagnostic Center of the Clinic Hospital of Barcelona provided the sequencing results After confirmation of the presence of mutations in the ALPL gene in the two patients available relatives were recruited to perform ALP blood measurements the reference values for adult males were 43-115 IU/L while for females were 33-98 IU/L MutPred, PROVEAN and Mutation Taster algorithms were used to predict the consequences of protein mutations. Combined annotation-dependent depletion (CADD) was used to rank mutations according to impact and was compared to the mutation significance cut-off (MSC) obtained for CADD scores (30) Both mutations have already been introduced into the VarSome database with references NM_000478:c.17T>C for the L6S variant and NM_001369805.2:c.498_500del for the T167del variant For 3D modelling, the complete atomic model was predicted using AlphaFold2_advanced (32). The models with the highest scores in the local distance difference test (pLDDT) were chosen. Finally, the visualization and preparation of the figures were performed using Chimera X software (33) Human embryonic kidney cells 293T (HEK293T) were used cells were cultured at 37°C and 5% CO2 with Dulbecco’s Modified Eagle Medium (DMEM) High Glucose (pH 7.2) (Biowest) supplemented with 10% fetal bovine serum (Capricorn scientific) 5% Ham’s F12 Nutrient Medium (Biowest) and 1% of 100X Antibiotic-Antimycotic (Biowest) The vectors used were constructed by modifying the pcDNA3.1 plasmid The ALPL gene with the study variants L6S (pcDNA3.1:ALPL c.17T>C) and T167del (pcDNA3.1:ALPL c.498_500delCAC) was inserted in this plasmid The pcDNA3.1 plasmid with the WT ALPL gene insertion (pcDNA3.1: ALPL) was used as a positive control to functionally characterize the identified variants The empty vector (EV) without insertion (pcDNA3.1) was used as a negative control to monitor the basal expression of the ALPL gene at the cellular level The different variants of the ALPL gene were inserted between the HindIII and BamHI restriction sequences belonging to the multi-cloning site 150000 cells were grown per well in 24-well plates transient transfection was performed by adding to each well 50 µL of serum-free DMEM containing 1.5 µL of LipoD293 DNA in vitro transfection reagent (SignaGen Laboratories) and 500 ng of the corresponding plasmid Co-transfections were carried out by mixing 250 ng of each variant with 250 ng of WT obtaining 500 ng of total reaction The cells were incubated for 18 hours with the mixture and after that time 2 mL of DMEM supplemented with serum was added the cells were incubated for 24 hours and harvested for the different assays The term homozygous will refer to cells transfected with a single plasmid while the term heterozygous will refer to cells co-transfected unless otherwise indicated the results were analyzed by using the ΔΔCt method Cell viability was determined by using FITC Annexin V Apoptosis Detection Kit I (BD Biosciences) following the manufacturer’s protocol Cells that were negative for both propidium iodide and Annexin V expression were considered viable cells while cells that were positive for Annexin V individually or together with propidium iodide Antigenic density was performed following the protocol developed by Lopez-Perez et al. (34) the cells were washed with PBS and incubated with 2 µL of BV421 Mouse Anti-Human Alkaline Phosphatase (BD Biosciences) for 20 minutes the cells were fixed with 4% formaldehyde for 20 minutes the cells were washed twice with PBS and resuspended in 100 µL To standardize the expression of TNSALP variants on cell membranes 5 µL of CountBright™ Absolute Count Beads (Invitrogen) were resuspended in 100 µL of PBS All results were obtained with the BD FACSAria III Cell Sorter flow cytometer (BD Biosciences) on a logarithmic scale Antigenic density was calculated as the ratio of the median intensities of the TNSALP-positive cells versus the median intensity obtained by the CountBrigh Absolute Count Beads TNSALP activity was measured at a wavelength of 450 nm by spectrophotometry (Dynex Technologies) using the Alkaline Phosphatase Detection Kit (Abnova) from cell extracts according to the manufacturer’s recommended protocol Each experiment was performed in triplicate Saphiro-Wilk test was used to test the normal distribution of data To evaluate the differences between groups the one-way ANOVA test was used followed by Tukey HSD P-values below 0.05 were considered significant All tests were conducted with GraphPad Prism 9.5.1 Table 1 shows the results of the biochemical analyses of each patient The blood ALP activity in Patient 1 (P1) and 2 (P2) had persistently low ALP activity (73 IU/L and 45 IU/L respectively) while the PLP concentration were 6.5 and 2.5 times higher (118 µg/L and 45.5 µg/L respectively) than the normal values gastroesophageal reflux disease (GERD) and dyspepsia vitamin D deficiency and high blood pressure (HBP) while P2 presented clinical manifestations related to autoimmune diseases such as Crohn’s disease and inverse psoriasis in addition to vitamin D deficiency P2 was treated with calciferol and immunosuppressants none of the patients presented pathognomonic symptoms of HPP both patients maintained persistently low levels of ALP activity (P1: 42 IU/L; P2 38 IU/L) Table 1 Anthropometric and clinical parameters of HPP patients P1 presented a missense mutation in heterozygosis in the second exon of the ALPL gene (c.17T>C) changing a leucine for serine in position 6 of the protein sequence (L6S). P2 was found to be heterozygous for a three-nucleotide in-frame deletion (c.498_500del) that resulted in the loss of the threonine residue at position 167 (T167del) in the TNSALP sequence. Figure 2A shows a schematic context of the newly identified variants at genomic Both mutations have not been previously described in the scientific literature as they have not been found in any database such as genomeAD LOVD or Clinical relevant Variation (ClinVar) (Web References) The results of the pathogenicity predictions are shown in Table 2 P1 showed a disparity of results regarding the prognosis of the severity of the disease caused by the mutation the P2 mutation was classified as pathogenic in all the programs used Table 2 Features of new mutations found in patients 1 and 2 Table 3 Clinical results of relatives affected with HPP To know the degree of conservation of the mutated amino acids, MSA was performed using TNSALP sequences. Twenty animal TNSALP sequences were chosen for MSA (Supplementary Figure S1) The results obtained demonstrated that the beginning of the sequence is quite poorly conserved except for three amino acids, M1, L6 and L8, which match all the sequences analyzed. Regarding the mutation of P2, the T167 matches throughout all aligned sequences (Figure 2C) After simulation in AlphaFold2_advanced, the highest-ranked predictions based on the pLDDT score were chosen for WT (Figure 3A) and both new variants Figure 3 TNSALP 3D modelling based on the algorithm developed in AlphaFold2_advanced and visualized in Chimera X (Web References) (A) shows the visualization of TNSALP WT top and bottom structure (B) shows the representation of the WT TNSALP and variant L6S signal peptide (C) shows the representation of the structural characteristics of the T167del mutation The shortening of the loop due to the deletion of T167 causes the loss of most of the hydrogen bonds including those that affect the catalytic site Results of ALPL gene expression by RT-qPCR showed that cells transfected with the mutated vectors and with the WT vector had a 45-55 fold change compared to EV (p<0.001). There was no significant difference between the mutations and WT (Figure 4A) Figure 4 In vitro characterization of TNSALP activity of studied variants Results are expressed as mean with standard deviation ANOVA was used for comparisons between groups (***p<0.001) (A) shows relative mRNA expression after overexpression of new ALPL gene variants in HEK293T cells The results were normalized using the housekeeping RPL13 (B) shows cell viability results obtained by flow cytometry The results of survival and apoptosis were represented as a percentage concerning the total count of the cells in each culture (C) shows TNSALP activity determination of the new ALPL variants The quantitative results of the ALP assay were expressed in International Units per milligram of protein (IU/mg) (D) shows determination of the dominant negative effect of the study variants Determinations were made by TNSALP activity and normalized per mg of protein Cell survival was not compromised in any of the cases. Figure 4B shows that all populations had high survival rates (92-89%) and low apoptosis rates (5-7%) no statistically significant differences were observed between any of the study groups TNSALP activity in transfected cells showed a decrease in two variants compared to the WT protein. As shown in Figure 4C with no significant differences with respect to EV whereas the L6S variant had a statistically significant higher activity compared to EV and the T167del mutation Regarding the measurements of the TNSALP activity in the co-transfections, lower activity is observed in those in which the mutations were used compared to those that used EV (Figure 4D) EV: WT presents a percentage of activity of 53.06% which represents half of the total activity obtained in cells transfected in homozygosis with the WT plasmid while L6S: WT and T167del: WT in heterozygosis presented an average activity of 36.33 These results confirm that although both variants generate a DNE the T167del variant exerts a greater effect than the L6S variant on the WT monomer The expression of TNSALP in the cell membrane was analyzed by flow cytometry in homozygosity and heterozygosity of each variant The WT variant expressed a significantly higher amount of surface protein (0.749) than the other variants There were no differences between the populations that expressed the T167del (0.27) and L6S (0.24) variants; however the cells that expressed T167del showed a greater amount of TNSALP on the surface than those cells that expressed EV (0.17) Figure 5 Determination of TNSALP localization on the cell surface of HEK293T cells (A) shows an example of flow cytometry gating and histogram in cells homozygous and heterozygous for TNSALP variants The internal control is represented by the histogram in pink C) show the percentage of TNSALP positive cells (B) and TNSALP relative expression on cell surface (C) in homozygosis ANOVA was used for comparisons between groups (***p<0.001 E) show the percentage of TNSALP positive cells (D) and TNSALP relative expression on cell surface (E) in heterozygosis previously undescribed variants in the ALPL gene have been identified in two 15-year-old male patients leading to the genetic screening of the patients’ relatives for better understanding and personalized management for affected families For T167del variant T167 could play an important role as a stabilizer of the active site since we found that it has a structural function providing stability to E332 a direct Mg2+ ligand that is part of the catalytic center Based on our results and previous scientific literature T167del variant has been classified as pathogenic This agrees with the results obtained for T167del (located close to the active center of the protein) which showed more severe DNE We have observed a decrease not only in the percentage of cells that express TNSALP but also in the amount of protein in the membrane the amino acid L6 could play an important role in the process of exporting TNSALP to the cell membrane which could explain the low antigenic density of TNSALP although the percentage of cells expressing this protein is higher the underlying mechanisms in the alteration of the cellular localization of the protein are unknown to date we suggest that the mutated protein could be taken to the proteasome for its complete degradation which would explain the low activity and antigenic density of both homozygous and heterozygous The computational 3D modeling and alignment linked to clinical results and functional analyses suggest that L6S variant could be classified as likely pathogenic associated with a mild HPP phenotype all the data collected suggest the classification of this variant as likely pathogenic with a moderate phenotype offering valuable insights for forthcoming research endeavors although it is difficult to establish a gene-phenotypic relationship of each variant described in HPP due to the participation of several external factors that enhance phenotypic variability it is important to identify and characterize new variants that serve as a starting point for future research and patient management we have identified two new previously undescribed variants that produce clinical manifestations of HPP more related to systemic diseases than to bone disorders Considering the results shown in this study linked to previous scientific evidence we suggest low ALP activity could be related to worsening of inflammatory/autoimmune disorders in HPP patients In this study we show that both new identified mutations could be classified as likely pathogenic and have a DNE that affects both

(2013); Straka and Baker (2013); Díaz and Puelles (2019)] This implies that the patterning of the hodological mosaic reflects an evolutionarily conserved mechanism that links position gene expression differences between rhombomeric domains contribute to creating functional diversity among vestibular projection neuron subpopulations has not yet been characterized developmentally Table 1. Transcription factor signatures of the vestibulospinal neuron groups relative to the rhombomeres [based on Lunde et al. (2019)] Vestibulo-ocular projections to the abducens nucleus have not yet been defined in the same hodological context With respect to the relationship between the hodologically defined vestibulo-ocular groups and rhombomeric domains, the cR-VO group relates to a single rhombomere (r1), whereas the iR-VO and cC-VO groups derive from multiple rhombomeres (r2-r3 and r5-r7, respectively; Pasqualetti et al., 2007) so the cC-VO group should contain predominantly excitatory neurons The cR-VO group is partially located in the ventral part of the caudal cerebellar peduncle in r1 (Figure 5E). This hodological cR-VO subpopulation was correlated with the infracerebellar nucleus by Pasqualetti et al. (2007) based on a comparison with mammalian literature Perhaps this r1-related cR-VO subpopulation whose axons project in the brachium conjuctivum is actually patterned as part of the cerebellar anlage by the isthmic organizer rather than as part of the vestibular column per se The relationship between hodologically defined vestibular groups with classically defined nuclei is summarized in Figure 6 contralateral vestibulo-ocular group; cMVST contralateral medial vestibulospinal group; DVe (SPVe) descending (spinal or inferior) vestibular nucleus; iMVST ipsilateral medial vestibulospinal

that comparative studies of the dorsoventral sources of these neuron groups are needed a segmental interpretation of morphological and developmental data has contributed to clarifying the anatomical and functional organization of the vestibular column wherein each rhombomere has a unique gene expression signature correlates with hodologically defined vestibular neuron groups with specific

To identify specific RP patterns, a principal component analysis (PCA) was performed using six RP parameters: AHI, oxygen desaturation index, mean and minimum oxygen saturation (SaO2), average duration of events and percentage of time with SaO2 < 90%. An independent HypnoLaus population-based cohort was used to validate the RP components. A RP component, mainly characterized by intermittent hypoxemia, is associated with a high risk of recurrent cardiovascular events in patients without previous CVD who have suffered a first ACS. Volume 9 - 2022 | https://doi.org/10.3389/fmed.2022.870906 Introduction: Obstructive sleep apnea (OSA) severity is based on the apnea-hypopnea index (AHI) The AHI is a simplistic measure that is inadequate for capturing disease severity and its consequences in cardiovascular diseases (CVDs) Deleterious effects of OSA have been suggested to influence the prognosis of specific endotypes of patients with acute coronary syndrome (ACS) We aim to identify respiratory polygraphy (RP) patterns that contribute to identifying the risk of recurrent cardiovascular events in patients with ACS Methods: Post hoc analysis of the ISAACC study including 723 patients admitted for a first ACS (NCT01335087) in which RP was performed a principal component analysis (PCA) was performed using six RP parameters: AHI average duration of events and percentage of time with SaO2 < 90% An independent HypnoLaus population-based cohort was used to validate the RP components PCA showed that two RP components accounted for 70% of the variance in the RP data These components were validated in the HypnoLaus cohort with two similar RP components that explained 71.3% of the variance in the RP data The first component (component 1) was mainly characterized by low mean SaO2 and obstructive respiratory events with severe desaturation and the second component (component 2) was characterized by high mean SaO2 and long-duration obstructive respiratory events without severe desaturation component 2 was associated with an increased risk of recurrent cardiovascular events in the third tertile with an adjusted hazard ratio (95% CI) of 2.44 (1.07 to 5.56; p-value = 0.03) compared to first tertile no significant association was found for the risk of recurrent cardiovascular events mainly characterized by intermittent hypoxemia is associated with a high risk of recurrent cardiovascular events in patients without previous CVD who have suffered a first ACS Cardiovascular diseases (CVDs) are one of the leading causes of death worldwide, and more than half are consequences of coronary heart disease, which is often manifested for the first time as acute coronary syndrome (ACS). Ranging from unstable angina to myocardial infarction, ACS is the main cause of morbidity and mortality worldwide (1, 2) The AHI does not provide information about apnea depth and length and is a simplistic measure that has many downsides and could result in inadequate capture of the severity of the disease Respiratory polygraphy (RP) allows the evaluation of a large number of physiological signals associated with respiratory disorders during sleep Polygraphic recordings include at least oronasal flow Dimensionality reduction technique allows the transformation of data from a high-dimensional space into a low-dimensional space so that the low-dimensional representation retains some meaningful properties of the original data The dimensionality reduction analysis of the signals of RP could contribute to the construction of models that would relate OSA to cardiovascular risk Available evidence supports that the indicators of cardiovascular risk in patients with OSA we aimed to evaluate the RP patterns that could contribute to identifying the risk of recurrent cardiovascular events in patients with a first ACS and without previous CVD Acute coronary syndrome was defined as the acute presentation of coronary disease with or without ST elevation infarction The ethics committee of each participating center approved the study (approval number in the coordinating center: 2010-852) and patients provided written informed consent The RP components in the ISAACC cohort was externally validated in the HypnoLaus population-based cohort (3), a nested-study of CoLaus/PsyCoLaus (15, 16) This study was designed to assess the prevalence of sleep-disordered breathing in a general population aged 35–75 years who were selected at random and were enrolled in the study Questionnaires to record demographic and anthropometric characteristics medical history and usual pharmacological treatment were administered the day before the sleep study along with questionnaires associated with quality of life (EuroQol-5D questionnaire) and the degree of daytime sleepiness (Epworth Sleepiness Scale test) All patients were evaluated at baseline and 1 month All patients were monitored and followed up for a minimum of 1 year sociodemographic and anthropometric variables previously related to increased cardiovascular risk were recorded Each follow-up visit included assessments of the rate of a composite of cardiovascular events [cardiovascular death or non-fatal events (acute myocardial infarction hospital admission for heart failure and new hospitalizations for unstable angina or transient ischemic attack)] we explored RP parameters to identify specific components We explored the contribution of RP components to the risk of recurrent cardiovascular events The cardiovascular risk variables explored were age, sex, current cigarette smoking, current alcohol consumption, obesity, hypertension, previous cerebrovascular disease, diabetes mellitus, and dyslipidemia (low-density lipoprotein cholesterol ≥100 mg/dL or the use of lipid-lowering drugs). Moreover, on the basis of cardiovascular risk prediction models (17, 18) we explored the following other cardiovascular variables: antihypertensive drugs no in-hospital percutaneous coronary intervention troponin and mean SaO2 Participants underwent full polysomnography at home. Details of the sampling and procedure methodologies have been described elsewhere (3, 15) we analyzed the data from 1941 HypnoLaus patients The ethics committee of the University of Lausanne approved the CoLaus/PsyCoLaus cohort study and the HypnoLaus Sleep Cohort study We obtained written informed consent from all participants The main characteristics were described using medians (25th percentile and 75th percentile) or percentages. The P value for trend was evaluated using Spearman’s rank correlation coefficient when data were continuous and non-normally distributed and the chi-square test for trend when they were categorical (19) Statistical analyses were conducted using R, version 3.6 (22) and statistical significance was set at 0.05 Baseline characteristics of patients from the ISAACC cohort The external validation cohort was 2,168 individuals from the HypnoLaus population-based cohort. Finally, 1941 individuals were selected without previous CVD and available data. The median age was 56.9 years, 47% were males, and the median AHI was 9.8 events per hour (Supplementary Table 3) The mean time of follow-up (or CV event) was 4.25 (standard deviation: 1.77) years Correlations between respiratory polygraphy parameters and components derived from the PCA accounted for 43 and 26% of the total variance accounted for 49.2 and 22.1% of the total variance Dashed lines represent –0.5 and 0.5 correlations Description of the respiratory polygraphy parameters by tertiles of the components derived from the PCA in the ISAACC cohort ISAACC patients were characterized using sociodemographic and clinical characteristics by tertiles of the two RP components (Supplementary Table 7) Patients with high adherence in component 1 had more comorbidities as the third tertile showed a greater proportion of patients with obesity Similar characteristics were shown by tertiles of component 2 In the same way, HypnoLaus subjects were described using sociodemographic and clinical characteristics by tertiles of the two RP components (Supplementary Table 8) Subjects with high adherence in component 1 had more comorbidities as third tertile showed a greater proportion of subjects with hypertension dyslipidemia and a higher body mass index (BMI) the third tertile showed a greater proportion of subjects with hypertension a lower proportion of subjects with dyslipidemia and no differences regarding BMI and diabetes In the present study, from the ISAACC study, we explored specific RP parameters and components (Supplementary Table 9) in the subgroup of patients admitted by a first ACS and without previous CVD (n = 723) In the subgroup of patients without previous ACS, OSA severity (measured by AHI) showed a trend toward statistical association [HR (95% CI) of 1.62 (0.98–2.66)] with an increased risk of recurrent cardiovascular events (Supplementary Table 10) In the analysis of RP components and the risk of recurrent cardiovascular events, it was observed that component 2 showed a significant independent association with the risk of recurrent cardiovascular events in patients with the highest adherence (3rd tertile) of component 2 with an adjusted HR (95% CI) of 2.44 (1.07 to 5.56). For component 1, no significant contribution was found to the risk of recurrent cardiovascular events (Table 3 and Figure 3) The discriminatory power of the models showed a C-statistic for the risk of recurrent cardiovascular events of 72.3% for patients without previous CVD Similar results were found exploring components from PCA as continuous [HR (95%CI): for Component 2: 1.38 (0.99–1.94) and for Component 1: 0.82 (0.6–1.13)] Cox proportional hazard model for the primary composite endpoint in the ISAACC cohort Hazard ratio for recurrent cardiovascular events by tertiles of respiratory polygraphy components in the ISAACC cohort and lines represent 95% confidence intervals hazard ratio (95% confidence interval); ACS *Significant p values (p < 0.05) In the HypnoLaus cohort the risk of recurrent cardiovascular event in patients with first ACS could not be assessed due to its population-based design the RP components identified in the ISAACC cohort were also identified in the HypnoLaus population-based cohort which captures only one aspect of this heterogeneous disease The ability to dissect OSA heterogeneity using additional features is necessary for incorporating personalized approaches in disease management we observed that the effect of OSA severity showed a trend toward a statistical association (with an HR of 1.62) with the risk of recurrent cardiovascular events in the group of patients without previous CVD indicating an increase in the risk of recurrent cardiovascular events we suggest that the analysis of other parameters from RP could contribute to the determination of RP components and their relationship with the development of recurrent cardiovascular events in patients who have suffered an ACS an estimation of the depth and duration of respiratory-related desaturation is an alternative metric associated with an increased risk of CVD mortality the authors of that study admit that this measure does not fully characterize the components of hypoxic stress because it does not distinguish short and deep desaturations from long and shallow desaturations we found that the component associated with recurrent cardiovascular events was component 2 The highest adherence to this component (3rd tertile) showing the highest risk of recurrent cardiovascular events higher mean SaO2 and longer event duration This tertile would suggest an intermittent hypoxemia component the lowest adherence to this component was characterized by lower AHI which would suggest a sustained hypoxemia component The results of the present study suggest that from available variables from RP it is possible to improve the evaluation of the risk of recurrent cardiovascular events with an HR of 1.61 exclusively with AHI to 2.44 considering additional variables The patients with the highest adherence to component 2 (3rd tertile) which represents an intermittent hypoxemia component strengthen the hypothesis that OSA exerts a risk in specific subgroups of patients with ACS the patients with the lowest adherence to this component would have a lower risk of recurrence of a cardiovascular event the same RP components were found in the HypnoLaus cohort suggesting that these components are not specific to the ISAACC population it was not possible to estimate the predictive nature of the identified RP components for recurrent cardiovascular events in this cohort the low number of available cardiovascular events due to its population-based design The existence of specific RP components that could be associated with detrimental effects in specific phenotypes of patients with ACS invites us to reconsider the design strategies of new interventional studies to demonstrate the possible beneficial effect of CPAP treatment on secondary CVD prevention. These preliminary results raise the possibility that, in studies such as the ISAACC study (8) no beneficial effect was seen because of the inclusion of patients with different phenotypes of ACS where OSA could have different effects The contribution of information about sleep phases should be explored in further studies the results from the present study may not be extrapolated to a population different from that of patients admitted to the hospital for ACS This fact makes it necessary to specifically identify phenotypes in patients with OSA who are attended in different clinical settings in patients who have suffered a first ACS and without previous CVD that is associated with a greater risk of recurrent cardiovascular events These first exploratory results must be confirmed in future studies which will evaluate the effect of RP components of specific ACS populations and the possible beneficial effect of CPAP treatment for patients with a first ACS and without previous CVD in whom a deleterious effect of this RP component has been found The original contributions presented in the study are included in the article/Supplementary Material further inquiries can be directed to the corresponding authors The patients/participants provided their written informed consent to participate in this study Concepcioìn Rodriìguez-Garciìa Francisco Javier Goìmez de Terreros Caro Abel Jesuìs Martiìnez-Garciìa and MS-d-l-T contributed to the study concept and design and RH contributed to the data acquisition and MS-d-l-T contributed to the data analysis and interpretation All authors contributed to the drafting of the manuscript critically revised the manuscript for important intellectual content and approved the final version MS-d-l-T is the guarantor of the manuscript Instituto de Salud Carlos III (ISCIII;

by PCR and an antibody test (ELISA and/or IPT) which we assumed would represent animals which had the infection for some time longer (Stage 2); or which were positive to the antibody test and the nucleic acid detection test was either not specified or negative which we assume would represent the latest stage of infection when ASFV detection decreases but immunity mounts leading to an increased percentage of survivors (Stage 3) For 1,160 notifications (<10% of the total 12,661) with no information on whether the wild boar was hunted or found dead or on the test used we assumed they were dead wild boar tested with PCR Wild boar notifications estimated to be in Stage 3 of infection comprise those with a positive antibody result together with either those that specifically state that a negative PCR has been obtained or those in which we assume the PCR has been negative because this diagnostic test result is not specified The estimated TWI was explored spatially by representing the distribution of natural breaks (Jenks) classification in a choropleth map in each administrative unit We explored whether there could be a correlation between the number of notifications in which antibodies were detected and the estimated TWI per administrative unit by computing Spearman's correlation coefficient Rho in R Core Team (24) where a p <0.05 was considered statistically significant The same analysis was also carried out with the proportion of notifications in which antibodies were detected and TWI The ASF wild boar notifications with positive serology were fitted a kernel density function in a map using geodesic distances between points and an output cell size of 0.034 sq km Both maps were developed in ArcGIS 10.2 (ESRI) and were compared qualitatively Lithuania and Poland mainly notified ASF in wild boar from dead animals Lithuania and Poland have increased the number of notifications in wild boar each year while Estonia's notifications in wild boar peaked in 2016 and Latvia's in 2017 Annual number of ASF notifications in wild boar The annual distribution of notifications by diagnostic test used and estimated stage of infection is shown in Table 1 9,882) were based on PCR results (Stage 1) The remaining 22% comprise 393 notifications that include both PCR and antibody positivity results (Stage 2) and 2,386 notifications based on antibody results only (Stage 3) Annual distribution of ASF notifications in wild boar by diagnostic test/s used and estimated stage of infection The apparent increase in notifications in Stage 3 can be better observed in Figure 2 where the proportion of notifications in each stage over the total ASF notifications in wild boar per year has been stratified by dead/hunted and by country the predominant diagnostic result is obtained by PCR In fact there are very few notifications (n = 15) in Stage 3 in dead wild boar: 2 from Latvia (one in 2015 the other in 2016) and the rest from Bialski there are some differences by country but not statistically significant according to a factorial ANOVA test the % of notifications based only on PCR results (Stage 1) has decreased since 2014 to give rise to the notifications based on antibody detection (Stage 3) A factorial ANOVA test for hunted wild boar in Stage 3 showed statistically significant differences by year particularly from 2016 onwards (Tukey's honest significant test Only Lithuania has not increased the % of antibody notifications by year 1,218 Stage 3 notifications are truly PCR negative antibody positive and in 1117 PCR is not mentioned 1,106 are from Latvia and exhibit an annual increasing trend (2015 = 158; 2016 = 282; 2017 = 297; 2018 = 369) and the remaining 108 are from Poland (2016 =1; 2017 =19; 2018 = 88) A Poisson regression model on the apparent annual increase of notifications in Stage 3 in Latvia indicates that it is statistically significant (p <0.01) The correlation test indicated an overall strong positive statistical association between ASF serology notifications and TWI by administrative unit (rho = 0.77 the correlation was weaker when considering the proportion of notifications based on antibody detection (rho = 0.35 Proportion of ASF wild boar notifications by estimated stage of infection over total ASF annual wild boar notifications Both Estonian virus were isolated from 2015 outbreaks In both regions ASFV has continued to circulate since 2015 since Valga is classified in the longest TWI category (3.5–5 years) and Tartu in the second longest (2.5–3.5 years) Both fall in an area corresponding to the second highest seroprevalence density category the virus recovered from a 2017 outbreak in Engures was non-hemadsorbing (non-HAD) This area has a TWI of only 1.5–2.5 years however it also falls into an area with the second highest seroprevalence density category Figure 4.

Sometimes obsession pays off.For the last 3 1/2 months has been obsessed with catching Kerry Silvers.On Wednesday was caught in Mexico as the result of a multi-agency effort Wojdylo coordinated Police say Silvers may have critical information about the disappearance and death four years ago of Jill Behrman a 19-year-old Indiana University student.Silvers was spotted in Mexico less than a week ago and Mexican authorities closed a net around him and snatched him up Silvers was working as a teacher and computer expert in his new home town little Martinez de la Torre on the Gulf of Mexico."The last 109 days this case has been my life," Wojdylo said of the search for Silvers whom he wanted to catch because Silvers might be able to provide key information in the Behrman case although he is not a suspect himself.Jill Berhman\'s parents attended the news conference.Wojdylo had good reason to seemed pleased with himself and his law enforcement colleagues Friday at a news conference in Indianapolis They\'d apprehended perhaps Indiana\'s most-sought-after felon-at-large.Silvers was wanted for escape from the Lawrence County Jail in May 2000 and from the Orange County Jail in April 2002 even if meant a life on the lam: The escape forestalled Silvers serving a 63-year prison sentence in Lawrence County on his conviction there for multiple felonies And it delayed his prosecution in Orange County on more than a dozen felony charges &#151; including attempted murder &#151; for the 2002 jailbreak in Paoli.Orange County Prosecutor Kelly Minton said at the news conference that any idea of cutting Silvers a deal to help with the Behrman case was it was a huge frustration to Indiana State Police Detective Rick Lang.Lang heads the Behrman investigation and previously had interviewed Silvers about a conversation Silvers had with Uriah Clouse the Ellettsville man who police have named as a suspect in the Behrman case.Two women told authorities that Clouse had hit Jill Behrman\'s bike with his truck then had taken her to Salt Creek North Fork stabbed her to death and dumped her in the creek But the story crumbled when Behrman\'s bones were found in a forest in Morgan County in March 2003.Clouse and Silvers had been in jail together at one point and investigators hoped Clouse may have told Silvers something about the case Lang said he\'d taken "great interest" in things Silvers had told him before his escape and flight to Mexico but Lang said he was not free to say what more he wants to learn from Silvers.Lang said since Silvers arrived in Indianapolis "I can say at this point that he is cooperative It remains to be seen what he will say to us Whether or not he will continue to speak with me is entirely up to him."As for Silvers\' capture Wojdylo outlined the process that led to his apprehension in Mexico &#151; as well as Silvers\' path there.Silvers and two other men had escaped from the Orange County Jail in Paoli on April 18 allegedly attempting to kill a dispatcher on the way out but Silvers evaded capture in the forests of Orange County for two days.He then made his way to Louisville just across the Rio Grande from Brownsville then moved to the state of Veracruz east of Mexico City eventually settling down in Martinez de la Torre.Wojdylo said every criminal makes "small but critical mistakes," and Silvers\' was that he was getting money from his mother in Lawrence County Wojdylo said Vickie Silvers sent her son $15,000 over 15 months &#151; something she may come to regret.Aiding a criminal in flight is a federal offense and Vickie Silvers will be the subject of discussion for possible prosecution by U.S and she knows I know it," Wojdylo said.He added that Silvers\' family had doubted marshals could catch him So Wojdylo said he took great pleasure in calling Vickie Silvers late Thursday to inform her that he had her son in custody.Before his capture Silvers had become a big man around town in Martinez de la Torre &#151; and hardly for bad things He was teaching English to children in the local school and his computer expertise was a major asset driving a new Volkswagen Jetta."He was very prominent in the community and was doing well," Wojdylo said.Until a week ago marshals quickly put together a two-country They then drove three hours to Martinez de la Torre where they began to stake out places Silvers routinely visited.The fugitive was spotted tooling around in his Jetta When Silvers stopped at a video store late in the day Wednesday followed by the marshals.Silvers was taken "after a brief struggle," Barfield said at the news conference decades of prison face him.Wojdylo said marshals flew back to the United States with Silvers early Thursday after a night of doing the paperwork Mexico required for his extradition They arrived in Indianapolis Thursday afternoon.Silvers initially was held in a cell at the Federal Building he was transferred to the Indiana Department of Correction.Wojdylo praised all the officials and agencies He and others also lauded the "America\'s Most Wanted" show for being instrumental in making the public aware of Silvers and the Behrman case.Another U.S former Bloomington Police Chief Jim Kennedy Just results," he said.Wojdylo said he was happy for Lawrence and Orange counties because Silvers "owes 61 years (of unserved time) to the county of Lawrence and I\'m sure Orange County would like to add to that."And Wojdylo whose obsession with catching Silvers began when he saw the "America\'s Most Wanted" account of the Behrman case said he hopes the capture leads to its resolution."It was \'America\'s Most Wanted\' that brought the case into my living room," he said adding he hopes it will lead to "closure" for Eric and Marilyn Behrman whom he said "deserve peace."He said it now falls to Lang who heads the ongoing Behrman investigation to wrap that up."My job is done," Wojdylo said.<i>Reporter Kurt Van der Dussen can be reached at 331-4372 or by e-mail </i>at kvd@heraldt.com IL — A new restaurant that serves up authentic Mexican food has opened in Lake in the Hills Rinoconcito de Vercruz is located in the former Cachas Taco Bar at 2122 W. Algonquin Road. Restaurant owner Luis Landa has been thinking about opening a restaurant for a decade and decided on Lake in the Hills after realizing the village did not have an authentic Mexican restaurant Business has been picking up at the new restaurant which has an extensive menu and serves up seafood dishes that are popular in Veracruz and the business is also working on acquiring a liquor license from the village of Lake in the Hills Once that is approved, cocktails such as margaritas, pina coladas and Veracruz-inspired drinks, including a cantarito — which is served in a clay jar and includes orange juice, grape juice, lime and spices with tequila —will be added to the menu.

MEXICO CITY — A weathered pastel image of the Virgin of Guadalupe hangs from German Herrera Hernandez's dashboard, watching over his passengers from her perch next to his cigarettes, gum and the handful of coins he uses to make change. "We believe in her," said Herrera, a 55-year-old who has been driving a cab in Mexico City for about a decade. "She protects us, wherever we go." When Pope Francis visits this week he'll make an emotional stop at the Basilica of the Virgin of Guadalupe — patron saint of Mexico and "empress of the Americas" — where millions of pilgrims flock each year to pray before the shroud that bears her image. But she's also an ever-present part of life for millions of people like Herrera, not just at the basilica. Across the country, in private homes and public marketplaces, she gazes down beneficently from the walls of taco stands and police stations, from hair salon mirrors and even outside no-tell motels. In poor barrios and posh shopping districts, perhaps nothing unites Mexicans more than their reverence for the Virgin. Grieving families light candles beneath her likeness in shrines to dead relatives, while young hipsters shell out big bucks for shirtsleeve tattoos of the Virgin. "There's the old refrain in Mexico that Mexicans are 90 percent Catholic and 100 percent Guadalupan," said Andrew Chesnut, chair in Catholic studies at Virginia Commonwealth University. "If there's one main constituent element of Mexican-ness, it's Guadalupe, because she obviously transcends the religious realm. ... So she sells products, she's tattoos, (even with) people who aren't necessarily her devotees." According to tradition, the dark-skinned virgin appeared before the Indian peasant Juan Diego in 1531 at Tepeyac, a hillside near Mexico City where Aztecs worshipped a mother-goddess, and her image was miraculously imprinted on his cloak. The image helped priests inculcate Catholicism among indigenous Mexicans during Spanish colonial rule, and the church later made her patron of all the Americas. Juan Diego was canonized as the hemisphere's first Indian saint in 2002 during the papacy of John Paul II. Juan Diego's cloak is on display today behind glass at the basilica, the most visited Marian shrine on the planet, where signs admonish against flash photography and long lines of worshippers are carried past along a self-moving walkway. Chesnut called Francis "a very strongly Marian pontiff" and said his visit to the basilica will be one of the defining moments of his trip to Mexico, which has more Catholics than any other Spanish-speaking country. Each year on Dec. 12, millions of people visit the basilica in northern Mexico City, many of them crawling or bearing statues of Guadalupe on their backs, to beseech all manner of favors: to be healed of an illness, freed from an addiction, for the welfare of loved ones. The rest of the year, many Mexicans make the sign of the cross when they pass Guadalupe shrines found in just about every nook and cranny of the country. Custodians make sure the shrines are always well-kept with offerings of fresh flowers or candles. At the Martinez de la Torre market in central Mexico City, a portrait of Guadalupe framed by neon tubes in the red, white and green of the Mexican flag graces a wall overlooking a meat counter. "Why have a Virgin? Because our faith in her is very great, very important," said butcher Erlinda Olivares Zuniga, who choked up when asked about Guadalupe ahead of Francis' visit. "We are God's chosen, because the Virgin appeared here." Volume 5 - 2018 | https://doi.org/10.3389/fvets.2018.00077 African swine fever (ASF) has spread from the Caucasus region to eastern European Union countries affecting domestic pig and wild boar populations mitigation measures targeting both populations have been established ASF has been reported in thirteen different countries (Georgia In the absence of an effective vaccine or treatment to ASF introduction and spread of ASF onto domestic pig farms can only be prevented by strict compliance to control measures This study systematically reviewed available measures to prevent the spread of ASF in the EU domestic pig sector distinguishing between commercial The search was performed in PubMed and using a common browser A total of 52 documents were selected for the final review process 37 measures were identified as preventive measures for the introduction and spread of ASF these measures were assessed by ASF experts for their relevance in the mitigation of ASF spread on the three mentioned types of farms All experts agreed that some of the important preventive measures for all three types of farms were: the identification of animals and farm records; strict enforcement of the ban on swill feeding; and containment of pigs so as to not allow direct or indirect pig–pig and/or pig–wild boar contacts Other important preventive measures for all farms were education of farmers and operators; no contact between farmers and farm staff and external pigs; appropriate removal of carcasses and food waste; proper disposal of manure and dead animals and abstaining from hunting activities during the previous 48 h (allowing a 48 h interval between hunting and being in contact with domestic pigs) all experts identified that the important preventive measures for non-commercial and outdoor farms is to improve access of those farms to veterinarians and health services The Directive lays down the measures to be taken in the infected area and the provisions to apply on the holdings of that area All control and eradication measures applicable are based on classical disease control methods These measures are applied in combination with strict quarantine and biosecurity measures on domestic pig holdings and animal movement control The Directive also requires that Member States develop and implement plans for the eradication of the disease the aim of this study is to review described measures to prevent the introduction and further spread of ASF in the domestic pig sector focused on the EU scenario An additional aim of this review was to assess the importance of these identified measures depending on the different pig farming systems (see materials and methods section) Adequate identification of relevant measures will allow for the creation of guidelines for pig producers to prevent the spread of ASF which is one of the identified goals of the COST Action 15116 Understanding and combating African swine fever in Europe (ASF-STOP) supported by COST (European Cooperation in Science and Technology) Scientific papers written in English (for reviewing convenience) between the last 39 years (1978 and 2017) were reviewed A list of key words was combined into a Boolean query to identify titles and/or abstracts of documents of interest The key words used (and any word containing the stem presented) were “African swine fever,” “Preventive measure/s,” “Biosecurity,” “Risk,” and “Pig farm.” The search terms applied were “African swine fever” AND [Preventive measure* OR Biosecurity OR Risk OR Pig farm] To make sure other relevant documents such as technical guidelines the literature search was performed following the same query on the internet using a common browser A two step-process was followed to select the literature relevant for the aim of this review A primary exclusion criteria was applied when reading title and abstract of found literature (abstract when available): (i) published before 1978; (ii) not related to the theme of this review; (iii) not related to the European scenario; and (iv) repeated document (already selected among retrieved results) the piece of literature would be kept for the next stage the full text of each selected piece of literature was screened documents (v) which full text was not available; (vi) no preventive measures were described; (vii) described preventive measures were not focused on ASF; or (viii) information on the theme was insufficient The explained process was individually performed by three reviewers following the mentioned exclusion criteria in order to cross-check selected literature and resolve any disagreement A group of experts was invited to participate in an expert opinion session to assess the preventive measures identified in this review Participants belonging to the COST (European Cooperation in Science and Technology) action: “Understanding and combating African swine fever in Europe” (ASF-STOP) supported by COST (COST Action 15116)2 were encouraged to suggest experts with relevant expertise in ASF prevention ASF epidemiology and the EU domestic pig sector the list of measures were reviewed by authors to ensure measures were accurate and clear 20 experts were invited to participate and contacted by email Experts were asked to assess the relevance of each described preventive measure by answering yes or no to the closed question: “Is this measure important for commercial and outdoor-farms?” “Importance” was defined as the perceived need for each measure Experts were asked to perform this assessment within the EU context experts were encouraged to suggest additional measures if they thought they were missing Results were recorded in an Excel datasheet (Microsoft Corp. Figure 1 shows the literature selection process and Table 1 compiles the selected literature The search made on PubMed database returned 168 scientific papers After applying the primary exclusion criteria 69 were selected for the second step of the review the full text was not available for 10 of them 59 scientific articles were selected for the second screening round The same search on a common browser returned 5,100 results of potential interest By applying the primary exclusion criteria 58 results were selected for the second round Flowchart summarizing the literature selection process (A) on PubMed database and (B) on a common browser Pieces of literature included in the review process After applying the second exclusion criteria and completion of the screening rounds 34 articles (25 retrieved from PubMed and 9 retrieved from the browser search) 4 official recommendations (meaning information coming from governmental authorities) and 5 technical guidelines were included in the review The rest of the documents including reports and guidelines were retrieved from the browser search Preventive measures described hereinafter were obtained from the 52 pieces of literature selected during the systematic review These measures were classified in four different groups: general prevented measures suggested for all types of farms (as some of them were common for commercial and three groups of suggested measures for each of the identified types of farms Specific preventive measures based on biosecurity have been proposed depending on the type of farm: commercial, outdoor, or non-commercial (15) Commercial farms are significantly larger in size and number of animals (18) and so, the economic and animal health impact of ASF is greater than on outdoor and non-commercial farms (24, 29) Finally, proper disposal of manure as well as dead animals and other removable material should be ensured (5, 58, 65). Containers and storage basins should accomplish with the minimum requirements for storage capacities recommended by the Best Available Techniques (71) Table 2 compiles the general preventive measures and specific preventive measures for commercial and outdoor farms described in this review General measures to prevent African swine fever spread on domestic pig farms plus specific measures focused on commercial (CM) A total of 12 experts participated in the assessment of the importance of identified preventive measures All of them completed the questionnaire and therefore their responses were included in the analysis Around 3% of assessed measures (2.85%) were categorized as “not applicable” preventive measure There was 100% agreement among experts (12 experts out of 12) that the identification of animals and farm records including animal movements; enforcement of the ban on swill feeding; and containment of pigs to not allow contact with pigs from other farms were important preventive measures for the three types of farms (commercial Other important preventive measures identified for all farms were education of farmers slaughter residues and food waste; proper disposal of manure and dead animals; and a 48 h (minimum) interval between hunting and being in contact with domestic pigs for all farm staff particularly those who work in an infected wild boar area all experts identified as important preventive measures for non-commercial and outdoor farms to improve access of those farms to veterinarians and health services Between eight and nine of experts considered that logistical arrangement for the entry and exit of animals including protocols regarding entrance of vehicles loading areas and role of pig transporters; quarantine period for purchased animals and quarantine rooms; and internal audits and evaluations to enforce biosecurity measures were not important preventive measures for non-commercial farms 10 experts concluded that control measures against flies were not an important preventive measure on outdoor farms Additional preventive measures were suggested by some experts such as the use of nets on animal facilities; establishment of pest control programs on farms; use of carbonic dioxide traps to check the presence of Ornithodoros ticks and change of boots before entering the farm and units several respondents wanted to emphasize the importance of measures already included in the questionnaire establishment of double fencing perimeter on outdoor farms; education of swine veterinarians and farmers paying especial attention to clinical signs and transmission routes; and discouragement of using the same injection syringes and instruments on different farms unless thoroughly disinfected sterilized Figure 2 and Table 2 summarize the results obtained for preventive measures on commercial Figure 2. Results of the assessment of identified preventive measures represented as percentage of yes (blue bars), no (red bars), and not applicable (gray bars) to (A) commercial farms, (B) non-commercial farms, and (C) outdoor farms. Listed preventive measures are described in Table 2 prevention is the main tool to avoid further spread of ASF or an endemic situation Both the systematic literature review as well as the expert opinion elicitation highlighted three main areas where preventive measures would be very relevant to halt ASF spread in the domestic pig population: (1) control of entries into the farm and (3) improvement of health services and education which contains the majority of measures reviewed in the systematic literature review aim at the improvement of biosecurity measures dealing with the replacement of animals in particular in relation with cleaning and disinfection facilities Very few outbreaks have led to secondary spread in the EU and there has been a significant progress in EU advice to improve preventive measures against ASF in non-commercial farms Farm location far from suitable wild boar areas and close to geographical barriers was classified as important by more than half of experts such measures were relevant to more experts on outdoor farms (9 experts) This slight difference might be explained because the likelihood of wild boar being in contact with pigs would be higher on outdoor farms (where biosecurity is intrinsically lower) than on commercial or non-commercial farms Experts who declined to consider it important refereed that this measure is almost unfeasible considering the ecological characteristics of the European continent some of the experts who considered it important wanted to highlight that such a measure would only be applicable to new holdings wild boar cases have continued being notified in the area suggesting that there is still room for improving the strategy or insufficient enforcement are the most common reasons to fail to comply with these measures and are directly related to the third main area of ASF prevention: improvement of health services and education to be able to effectively influence farm workers it is essential to analyze the “at-risk” practices that depended on human behavior which can perpetuate ASF spread and find out measures tailored to each specific situation prevention of ASF becomes very challenging for the European pig sector a safe and effective vaccine is still lacking control and eradication of this disease still relies on rapid detection in field followed by the application of strict sanitary measures biosecurity is the only tool farms have to prevent the introduction of ASF joined efforts focusing on the domestic pig sector and wild boar need to be applied in parallel we will move forward to the final goal of eradicating ASF from the second largest world’s pork producer African swine fever is currently one of the major threats to the pig production in the EU biosecurity is key to prevent its spread between and within domestic pig farms This study identified thirty-seven preventive measures aimed at reducing the spread of ASF among domestic pigs These measures were also assessed by ASF experts within the framework of the EU scenario the most important preventive measures for commercial and outdoor farms were the identification of animals and farm records; enforcement of the ban on swill feeding; and containment of pigs to not allow contact with pigs from other farms other measures were considered relevant in preventing ASF introduction farm staff and external pigs; appropriate removal of carcasses slaughter residues and food waste; proper disposal of manure and dead animals and abstention from hunting activities for a period of 48 h prior to any contact with domestic pigs all experts considered important to facilitate and promote the access of veterinarians and health services to non-commercial and outdoor farms Adequate implementation of these measures can lead to significant advances in ASF prevention and control and possibility contributing to the eradication of ASF from the EU pig sector All authors contributed to the literature review performed to build this review CJ compiled the whole information and wrote the manuscript and SB designed the questionnaire for the assessment of preventive measures CJ analyzed results from the expert opinion and AT participated in the creation of the argument line of this the text All authors contributed to the critical review of the manuscript and approved the final version HF was employed by company GD Animal Health Research Institute All other authors declare no competing interests The reviewer AB and handling Editor declared their shared affiliation This article is based upon work from COST Action 15116 Understanding and combating African swine fever in Europe (ASF-STOP) supported by COST (European Cooperation in Science and Technology) CJ is the recipient of a Spanish Government-funded PhD fellowship for the Training of Future Scholars (FPU) given by the Spanish Ministry of Education MM-A has been financed by the INIA funded project AT-2015-002 Carla Rowe for her help during the review of the manuscript as well as the three referees for their valuable comments and great ideas suggested to get to the final version of this article Transmission routes of African swine fever virus to domestic pigs: current knowledge and future research directions Google Scholar African swine fever: how can global spread be prevented Philos Trans R Soc Lond B Biol Sci (2009) 364(1530):2683–96 Preventive measures aimed at minimizing the risk of African swine fever virus spread in pig farming systems Thirty-five-year presence of African swine fever in Sardinia: history evolution and risk factors for disease maintenance Transbound Emerg Dis (2016) 63(2):e165–77 7.

Sign up Explore our Food Tours → Mexico City is blessed with great weather all year round Summer is not very hot because it’s the rainy season things cool down very fast as soon as the rain starts falling and even early afternoons in summertime can make us break out in a sweat Two of the many delicious ways we have to cool down are paletas (popsicles) and raspados (shaved ice) Paletas and raspados are popular treats all over Mexico but they’re especially popular among schoolkids It’s common to see paleta and raspado vendors around schools waiting for eager little customers at the end of any school day Paletas in Mexico are divided into two main categories: de agua (generally made with fruit juice) and de leche (made with milk) and the flavors are usually those that complement milk arroz con leche (rice pudding) and chongos zamoranos (a typical dessert from the state of Michoacán that is made by boiling milk and adding sugar until only the curds are left) Paletas de agua flavors can be anything from the classic lime and tamarind flavors to “exotic” ones such as kiwi One of our favorite places to get a taste of these kinds of flavors not only in paletas but also in ice cream and sorbets a small shop in Colonia San Rafael that imports its products from Pachuca It’s a great place to sit down for a while and enjoy a good exotic paleta Ice cream parlors are abundant in the neighborhood of Coyoacán One of our favorite parlors is Helados Siberia which has been in business for almost a century and sells a delicious yogurt paleta When you walk the streets of Mexico City, or any other Mexican city for that matter, the brand you see popping up everywhere is La Michoacana This ice cream maker is one of the most recognized in Mexico when a little ice cream parlor started selling popsicles and ice creams in the town of Tocumbo and by the 1990s there was at least one La Michoacana in every plaza of Mexico’s most important cities There are more than 30,000 stores nationwide sometimes several in the same neighborhood But is it worth stopping at one for a paleta or ice cream La Michoacana products are made with natural ingredients and the paletas de agua and aguas frescas have a high fruit content Raspados are another much-loved after-school treat for kids you’ll see vendors pushing carts with big blocks of ice all over the city They usually shave the ice by hand and place the shavings in a plastic bag or cup One of our favorite places to get raspados is at Raspados Sonia in the Mercado Martinez de la Torre in the Guerrero neighborhood Editor’s note: It’s Beat the Heat Week at Culinary Backstreets we’re sharing some of our favorite spots to visit when the summer temperatures soar loading map -

Embryos and larvae were classified according to Nieuwkoop and Faber (1967) and metamorphic (59–65) stages were used minimizing as much as possible the number of animals used All animals were treated according to the regulations and laws of the European Union (86/609/EEC) and Spain (Royal Decrees 1201/2005) for care and handling of animals in research after approval from the University to conduct the experiments described Adult Xenopus were purchased from commercial suppliers (Xenopus Express; France) and the different developing specimens were obtained by in vitro fertilization and maintained in tap water at 20°C throughout their development embryos and larvae were deeply anesthetized in a 0.4-mg/ml solution of tricaine methanesulfonate (MS222 and late larvae were perfused transcardially with 0.9% sodium chloride followed by cold 4% paraformaldehyde in a 0.1-M phosphate buffer (PB The brains were removed and kept in the same fixative for 2–3 h they were immersed in a solution of 30% sucrose in PB for 4–6 h at 4°C until they sank embedded in a solution of 20% gelatin with 30% sucrose in PB and stored for 6 h in a 3.7% formaldehyde solution at 4°C The brains were cut on a freezing microtome at 40 μm (adults) or 20–30 μm (juveniles and late larvae) in the transverse or sagittal plane and sections were collected and rinsed in cold PB The embryos and premetamorphic larvae were fixed by immersion overnight at 4°C in MEMFA [0.1 M MOPS (4-morpholinopropanesulfonic acid) 2 mM ethyleneglycoltetraacetic acid then they were processed in toto and finally sectioned at 14–16 μm thickness in the transverse A immunohistofluorescence procedure was conducted with the primary antibody on the free-floating sections that was diluted in 5–10% normal serum of the species in which the secondary antibody was raised in PB with 0.1% Triton X-100 (Sigma) and 2% bovine serum albumin (BSA as follows: (1) Incubation for 72 h at 4°C in the dilution of the primary antibody mouse anti-Nkx2.2 (1:500; Developmental Studies Hybridoma Bank Clone: 74.5A5) and (2) the second incubation was conducted for 90 min at room temperature with the labeled secondary antibody Alexa 488- conjugated goat anti-mouse (1:500; Molecular Probes; catalog reference: A21042) the sections were mounted on glass slides and coverslipped with Vectashield mounting medium (Vector Laboratories The cocktails of primary antibodies were diluted in PB with 0.1% Triton X-100 and used for 60 h at 4°C.

University of Washington; Ekker et al., 1995) and xDll4 (provided by Dr. Nancy Papalopulu. University of Manchester; Papalopulu and Kintner, 1993) Hybridization step was done with 3 μl/ml of a DIG-labeled RNA probe in a 50% formamide containing medium overnight at 55°C The solution used for prehybridization (at 60°C for 1 h) and hybridization contained 50% deionized formamide (Fluka 5× standard saline citrate (Sigma-Aldrich 0.5% 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS; Sigma-Aldrich) 5 mM of ethylenediaminetetraacetic acid (Sigma-Aldrich) and 50 g/ml of heparin (Sigma-Aldrich) in water Hybridization was detected using an alkaline phosphatase coupled anti-DIG antibody (Roche Diagnostics Alkaline phosphatase staining was developed with Fast red tablets (Roche Diagnostics) The in situ hybridization was followed by the immunohistochemistry for mouse anti-Nkx2.2 (1:500; DSHB) revealed with Alexa 488-conjugated goat anti-mouse (diluted 1:500 embryos and early larvae were immersed in a solution of 30% sucrose in PB until they sank embedded in a solution of 20% gelatin and 30% sucrose in PB and stored overnight at 4°C in a solution of 4% formaldehyde and 30% sucrose in PB Sections were cut at 14–25 μm thickness in the frontal and horizontal plane on a freezing microtome The sections were analyzed with an Olympus BX51 microscope that was equipped for fluorescence with appropriate filter combinations Selected sections were photographed by using a digital camera (Olympus DP72) Contrast and brightness of the photomicrographs were adjusted in Adobe PhotoShop CS3 (Adobe Systems CA) and figures were mounted in Canvas 11 (ACD Systems Photomicrographs of sagittal (A–D) and transverse (E–P) sections through the Xenopus forebrain subdivisions along the different representative developmental stages The sagittal sections show the almost continuous Nkx2.2 expression from anterior hypothalamic areas to the most caudal regions of the forebrain (A–D) Nkx2.2 is not expressed in telencephalic areas Nkx2.2 expression starts in the SPV territory of the alar hypothalamus (E–H) In the basal hypothalamus Nkx2.2 expression is restricted to the tuberal hypothalamus (I–L) Nkx2.2 is observed in the three prosomeres (P1–P3) and the Zli lacks Nkx2.2 expressing cells (I–P) preoptic commissural area/commissural septo-preoptic area; PO 100 μm (D,H) and 50 μm (A,B,C,F′,G′,I) In Xenopus, Nkx2.2 immunoreactive (Nkx2.2-ir) cells were not observed in telencephalic areas, neither evaginated nor non-evaginated territories, from early developmental stages through the juvenile, when the brain morphology is close to that observed in adults (Figure 1) In order to further characterize the localization of Nkx2.2-ir cells within the forebrain, we carried out double labeling experiments throughout development, using different prosencephalic markers (Figures 25) Figure 5. Photomicrographs of transverse (A,B) and horizontal (C) sections through the forebrain illustrating Nkx2. 2 expression in combination with xShh. The expressions of Nkx2.2 and xShh extend along the anterior–posterior axis in parallel adjacent stripes, forming longitudinal columns along the forebrain. Abbreviations as in Figure 1 All the results obtained from the double labeling analysis confirmed the localization of the Nkx2.2-ir cells in the regions described above and summarized in Figure 6 Figure 6. Schematic drawings of sagittal and coronal sections through a premetamorphic brain of Xenopus laevis illustrating the distribution of Nkx2.2 expressing zones (green regions in the sagittal view) and cells (green dots in the coronal view) along the forebrain. The appropriated levels of the coronal sections are indicated in the sagittal view. Abbreviations as in Figure 1 To fully understand the precise topological distribution of Nkx2.2 expression its combination with the respective expression of different forebrain markers has been shown to be extremely useful we have analyzed the distribution of Nkx2.2 in combination with the localization of Nkx2.1 and in situ hybridization for the detection of xShh and xDll4 Shh and Nkx2.2 are not always expressed in the same regions Nkx2.2 expression is not detected in a comparable region given that the most anterior expression found coincides with the Otp SPV expressing zone within the hypothalamus (see below) On the basis of combined expression analysis, at least two different longitudinal alar domains have been proposed in the chick hypothalamus: the Dlx- and Shh-negative SPV area, which lies under the border of the FoxG1-positive telencephalic field, and the subparaventricular area, which lies under it and is adjacent to the Shh-positive basal plate, and expresses Dlx5 and Nkx2.2 (Bardet et al., 2010) the most anterior Nkx2.2 positive cells were localized in a Shh−/Nkx2.1−/xDll4−/Otp+ territory forming a thin strip of cells that delimit the region just anterior to the SC (present results) and their localization within this distinct region is highlighted because some of these cells contain both Otp and Nkx2.2 given the close spatial relationship between Shh and TH expressing neurons in the SC of Xenopus a possible implication of Shh/Nkx2.2 may exist for the acquisition of the dopaminergic phenotype in this region suggesting that Nkx2.2 could be implicated in the acquisition of the GABAergic phenotype Interestingly, also in Xenopus, Nkx2.2 expression is observed in the prethalamus, and its precise localization is corroborated by the colocalization of the Nkx2.2 expressing cells in the territory of P3 that is xDll4+/Nkx2.1+/Pax6+/TH+/xShh+ (present results; Bachy et al., 2002; Brox et al., 2003; Moreno et al., 2008a,b; Domínguez et al., 2010) and that xShh-expression in the Zli could lead to establish the Nkx2.2 expression pattern in the P2/P3 territory of amphibians This work supported by grants from Spanish MICINN and the UCM (Grant numbers: BFU2009-12315 and BSCH-UCM GR58/08) Ruth Morona for the fruitful discussions about the diencephalic regionalization and to Dr López for the critical reading of the manuscript Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text CrossRef Full Text CrossRef Full Text CrossRef Full Text CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text CrossRef Full Text CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text | CrossRef Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text Pubmed Abstract | Pubmed Full Text González A and Moreno N (2011) Ontogenetic distribution of the transcription factor Nkx2.2 in the developing forebrain of Xenopus laevis Copyright: © 2011 Domínguez This is an open-access article subject to an exclusive license agreement between the authors and Frontiers Media SA provided the original authors and source are credited *Correspondence: Nerea Moreno, Faculty of Biology, Department of Cell Biology, University Complutense of Madrid, C/José Antonio Novais 2, Madrid E-28040, Spain. e-mail:bmVyZWFAYmlvLnVjbS5lcw== COVID-19 Resources.

fugitive who escaped from Lawrence and Orange County Indiana jails - and who may have information on the murder of IU student Jill Behrman - has been captured in Mexico and brought home Behrman went missing while on a bike ride in Monroe County in May 2000 Her remains were found in a secluded area of Morgan County north of Paragon in March 2003 but investigators have said they believe that the escapee has had conversations with a primary suspect in the case 1,900 miles away from the Orange County Jail where police had last seen him Silvers\' was profiled twice on the FOX TV program "America\'s Most Wanted" in segments on Jill Behrman\'s death Police have said that Silvers is not suspected of being involved in Behrman\'s disappearance and death but police said he was being sought for questioning.While in jail Silvers reportedly had conversations with Uriah Clouse an Ellettsville man who had been named as a suspect in the Behrman case.Remains belonging to Behrman were found by a father and son out tracking game in early March 2003 in a wooded area near Duckworth and Warthen roads.Clouse has never been charged in her disappearance or death Silvers had eluded authorities for nearly 1,000 days and Orange County Sheriff Doyle Cornwell is happy to see him behind bars once more."That was a good Christmas present for me," Cornwell said "He was a very dangerous type individual and I was scared to death that someone else would get hurt before we got him off the streets he\'ll have 150 years to decide if it was worth it."Silvers escaped from the Orange County Jail on April 18 Two years earlier he had disappeared from Lawrence County Jail.Authorities finally caught up with Silvers late Wednesday in the small village of Martinez de La Torre Marshals returned him to Indianapolis Thursday.Police officials held a press conference in Indianapolis this morning announcing Silvers\' capture That press conference did not happen before press deadline this morning.Earlier Cornwell said there is a chance that Silvers will return to his jail in the future."Extra extra precautions will be taken if and when that person is incarcerated at my facility," he said "During visitation is when it (the escape) happened He will not have those privileges and will be in solitary confinement and will have no access to other inmates He is an extremely intelligent con-artist."Cornwell said his department had learned from the experience and changes have been implemented CAMAGÜEY.-The Ballet of Camagüey (BC) premiered this Friday a suite of the ballet The Nutcracker allows us to follow the thread of the Christmas story around a broken gift and Clara's dream that motivated the work premiered in 1892 with choreography by Lev Ivanov book by Marius Petipa and music by Piotr I a former BC dancer and current artistic director of the Kentucky Ballet Theater but the COVID-19 pandemic slowed down the process I feel satisfied because it is a dream come true they cannot be trusted because there is no perfection in ballet,” he declared to Adelante He was a professional dancer at BC from 1988 to 1993 then he went to Mexico to work as a principal dancer and since 2017 he has been collaborating as a guest choreographer for the company founded by Vicentina de la Torre and which counted Fernando Alonso “Artistic maturity occurs with the same experience that dancers can use on stage Shirley has to keep trying harder because her role is technically demanding and difficult to achieve,” he added children from the Fernando Alonso Dance and Ballet Promotion Center appear in the first act and in the party and snow scenes which promotes the active role of the family and their union Due to the injury of the prima ballerina Rosa María Rodríguez Armengol assumed the leading role of Clara and she has been with the company for three years “It is a great honor and a joy to have the opportunity that I have had dealing with adverse situations but as long as there is passion and dedication also with the aspiration of other roles in the repertoire She looked elegant together with the couple Harold Báez Corona and claims to appreciate the choreography from the first moment: “It is a very beautiful version but enjoyment must take precedence over everything and that was the case” as well as a bit of nerves knowing that an audience eager to see good results awaited us Former dancer and rehearsal teacher Liuba Corzo prefers to relate Shirley's first time as a leading lady with how new The Nutcracker is for the company: “We are very happy because we have been trying to do it for years therefore we cannot compare ourselves with ourselves” the prevalence in the current BC of members at the beginning of their career is evident: “There is a missing link between when you leave school and enter the company because they come with the technique but details need to be polished” the maître Hilda María "Lila" Martínez de la Torre and Regina Balaguer received recognition from cultural institutions higher education and the Union of Cultural Workers in the territory president of the Provincial Council for the Performing Arts described the 55th anniversary as an "act of sincere reverence for such commendable dedication," and highlighted the collective's understanding of art "as an event of vital relevance in the ethical Regina Balaguer praised the dedication of BC workers technicians and administrators to overcome obstacles in the country's circumstances exemplified in sessions without electricity: "If six rehearsals have been done with music That reason for discomfort in daily life made her doubt about the attendance of the public due to the blackouts however she received the satisfaction of a full Principal Theater it is not the complete choreography because the conditions did not allow it We will continue perfecting our work because our public from Camagüey and invited to the next performance of The Nutcracker suite this Sunday Reproduction is allowed when mentioning the source The chief of the Police Regional Office-Davao (PRO-11) has been relieved from his post effective Friday PRO-11 said the relief of Brigadier General Aligre Martinez may have something to do with the serving of arrest warrants against Kingdom of Jesus Christ (KOJC) leader Pastor Apollo Quiboloy and five others on June 10 “It is one of the considerations,” PRO-11 Spokesperson KOJC and former President Rodrigo Duterte have condemned and called the service of the warrants ‘excessive and overkill.’ However police maintained that it was a lawful operation Police Brigadier General Nicolas Torre III has replaced Martinez “Confirmed na na-relieve po ang current Regional Director ng Police Regional Office 11 Police Brigadier General Aligre Martinez effective June 14 At siya po ay papalitan ni Police Brigadier General Nicolas Torre III,” Dela Rey said Martinez was installed as PRO-11 chief on April 25 replacing Brigadier General Alden Delvo who retired from the police service Martinez will be reassigned to the Police Holding and Accounting Unit in Camp Crame was the former chief of the Quezon City Police District He resigned from his post amid the investigation into the road rage incident involving a former policeman and a cyclist He will leave his current post as director of the PNP Communications and Electronics Service to
