April 04th, 2022 Brazil, Latin America & Caribbean, News, Previews & Recaps
The first finals session of the 2022 Brazil Trophy saw a handful of FINA ‘A’ cuts achieved. In the women’s 100 breast, Jhennifer Conceicao roared to a new Brazilian Record of 1:07.12 to grab a decisive victory
Not only was a performance a new national record and personal best
Conceicao cleared the FINA ‘A’ standard of 1:07.43 in the event
earning her a spot on Brazil’s World Championships roster
Conceicao used her speed on the front half of the race
getting out to a 31.32 start on the first 50 of the race
In the men’s 400 free, Guilherme Costa downed the Championship Record, swimming to a 3:47.42 for his fastest time of the year so far. Fernando Scheffer
the Tokyo 2020 Olympic Bronze medalist in the 200 free
Scheffer just dipped under the FINA ‘A’ cut of 3:48.15
meaning both Costa and Scheffer have qualified to swim the event at the World Champs this summer
both Costa and Scheffer were already qualified for Brazil’s World Champs roster by virtue of qualifying for an Olympic final last summer
Scheffer was already on the roster in the 200 free
while Costa is already slated to race the 800 free
In a great race, Felipe Silva and Joao Gomes went head-to-head in the men’s 100 breast
Gomes matched his prelims time of 1:00.01 for 2nd
both men were just off the FINA ‘A’ time of 59.75
which they needed in order to qualify for World Champs
Viviane Jungblut roared to victory in the women’s 400 free
although she would go on to win the race by 4 seconds
Jungblut came in well under the FINA ‘A’ cut
and nearly took down the Brazilian Record in the process
Swimming a tough double of both the 400 free and 400 IM, Gabrielle Goncalves won the latter
The time comes in 10 seconds under her prelims swim of 4:56.36
but Goncalves was still well off the FINA ‘A’ standard of 4:40.06
meaning Brazil won’t have a representative in the event at Worlds this summer

The class of imidazolium salts contains effective anticorrosion additives for metal substrates
This study evaluated the potential of 1-carboxymethyl-3-methylimidazolium bis (trifluoromethylsulfonyl) imide (HO2CC1MImNTf2) for application in cultural heritage
exploring it as anticorrosion additive in chitosan-based coatings for the protection of copper-based alloys
Under accelerated corrosion conditions with HCl vapor
the chitosan coating with HO2CC1MImNTf2 was less effective than the one with benzotriazole
The coating with a combination of HO2CC1MImNTf2 and benzotriazole resulted in the optimal protective efficacy of the bronze surface
and it also maintained high transparency without changing the bronze appearance
moisture or marine aerosol from outdoor environment can start the degradation processes
Aggressive species such as volatile organic compounds
can be also present in indoor environments due to inadequate aeration
Imidazolium salt explored in this study
Imidazolium salts tested in the selection step
The degradation processes in bronze objects are very complex and can be induced by several species
chloride ions were selected to perform the tests since they are among the most aggressive degrading agents for copper-based alloys
it was possible to rapidly obtain information about the protective efficacy of the investigated formulations
with chemical composition and dendritic metallurgical structure similar to those commonly used in bronze objects of art
In this work the comprehensive results related to the morphological
chemical and functional characterization of the best CHT-based coatings modified with BTA
HO2CC1MImNTf2 and the mixture BTA- HO2CC1MImNTf2 are reported
does not affect the esthetical characteristics of pristine CHT-based coating and
when used at 35 wt% with respect to CHT and in the presence of 2 wt% of BTA
has a positive effect on the anticorrosion effectiveness of the resulting coating when compared to the CHT system containing only 2 wt% of BTA
This result is likely ascribed to an improvement of interfacial adhesion between the CHT matrix and the metal substrate
this preliminary study on the active protection of bronze alloys with CHT-based coatings modified with BTA and the IS HO2CC1MImNTf2 is innovative and similar uses of IS in cultural heritage were not reported so far

The incubation was performed at 37 °C (5% CO2
97% air humidity) for 1 and 5 days of exposure
Italy) was used as a redox indicator to evaluate biocompatibility
This assay quantified the redox indicator that changed to a fluorescent product in response to chemical reduction by mitochondrial enzymes such as dinucleotide adenine flavin dehydrogenase and dinucleotide adenine nicotinamide dehydrogenase
providing a quantifiable indication for the metabolic activity of living cells
the medium was removed and a 200 μL aliquot of diluted Alamar Blue (1:10) in red phenol-free medium (GIBCO® by Life Technologies
100 μL of each solution was transferred to a 96-well plate for colorimetric analysis (n = 4)
Wells without any cells were used to correct any background interference of the redox indicator
Cell viability was correlated with the magnitude of the dye reduction and expressed as % AB reduction according to the manufacturer’s protocol
The pure CHT formulation (CHT) was prepared by adding the CHT powder (1.0 wt%/vol%) to an aqueous DGL solution (0.05 M) and then the mixture was kept under stirring for 24–30 h to achieve complete solubilization of the polymer
The final pH of the solution was adjusted to 6 by the addition of 1 M sodium hydroxide solution
The corrosion inhibitor BTA (2.0 wt% with respect to CHT) was added to the CHT suspension from DGL (pH = 6) to prepare the formulation CHT/BTA
The formulation CHT/IS was prepared by dissolving 35 wt% (with respect to CHT) of HO2CC1MImNTf2 in the water/ethanol CHT solution from DGL (pH = 6)
The CHT/BTA-IS formulation was prepared by adding both BTA (2.0 wt% with respect to CHT) and HO2CC1MImNTf2 (35 wt% with respect to CHT) to the pure CHT solution from DGL (pH = 6)
All the solutions were diluted with ethanol to obtain formulations with a final water/ethanol composition of 50/50 vol%/vol%
The coatings were prepared by solvent casting
dropping 320 μL of the water/ethanol CHT-based formulations on the reference bronze disks with a diameter of 30 mm and subsequent drying overnight at rt

after 1 day and 5 days (CTR = control = IS- and BTA-free)
To assess the efficacy of the CHT-based coatings functionalized with the IS HO2CC1MImNTf2 and/or BTA
a copper-based alloy was used as metal model substrate
The alloy disks were polished to obtain a flat and smooth surface with a mirror-like finish
Surface analysis by AFM enabled the determination of the root mean square roughness
The preparation of CHT-based formulations was optimized to obtain uniform
compact and transparent films after deposition on Cu-based disks and drying
DGL was used to solubilize the polymer and an ethanol/water mixture with composition of 50/50 vol%/vol% was selected as liquid medium (formulation CHT)
The commonly used corrosion inhibitor BTA (2 wt% with respect to CHT; formulation CHT/BTA)
the IS HO2CC1MImNTf2 (35 wt% with respect to CHT; formulation CHT/IS) and the mixture of BTA and HO2CC1MImNTf2 (2 and 35 wt% with respect to CHT

The corresponding initial part of the nanoscratch curves (applied normal load between 5 and 30 mN) is also given for the same coatings; the curves have been vertically shifted for the sake of clarity
the positively charged CHT matrix (rich of ammonium ions due to the solubilisation performed in acidic conditions) may strongly compete with the imidazolium cations of the IS to interact with the functionalized substrate
the polymer forms a continuous film that protects the substrate and increases the adhesion to the metal of the modified film:
With the aim to investigate the protective efficacy of the developed coatings
all the coated disks were subjected to accelerated corrosion treatments and the occurrence of surface modifications was observed at different time intervals by optical microscopy
In the case of the coatings CHT and CHT/IS, significant modifications of the alloy surface were observed after 6 h of accelerated corrosion test (Fig. 8).

CHT/IS (blue triangles) and CHT/BTA-IS (green diamonds)
The obtained results show that the coating CHT/BTA-IS is able to protect the copper alloy surface
avoiding the formation of degradation product
These results also suggest that HO2CC1MImNTf2 plays an important role increasing the stability and the protective properties of the CHT/BTA formulation
IS HO2CC1MImNTf2 was investigated as potential novel corrosion inhibitor
Although this IS is less effective than BTA in the protection of bronze substrate
the use of HO2CC1MImNTf2 in combination with BTA improves the protective efficacy of the CHT-based formulation
showing a synergistic effect of the two additives
This result is of particular interest for the development of more sustainable and less toxic materials for the conservation of cultural heritage

Brazil and FAO are to work closely together to strengthen food security in the Southern African country by boosting its agricultural and veterinary research
Under a new South-South Cooperation agreement
Angolan researchers will receive technical assistance and short-term training from the Brazilian Agricultural Research Corporation (EMBRAPA)
which played a key role in Brazil’s successful domestic programme to drastically reduce hunger
“The availability of highly qualified researchers and innovators who understand the complexity of development challenges is key to making great strides in agriculture and food security in Angola,” said Laurent Thomas
FAO Assistant Director-General for Technical Cooperation
“Brazil has much to offer in terms of proven technical know-how and this agreement is an important milestone in South-South Cooperation between the two countries
We believe it is a model that we hope will be followed by other countries of the global South.”
the two-year project will be co-financed by Angola and Brazil
with Angola covering the $2.2 million financial costs and Brazil providing an in-kind contribution of $875 000 through the work of EMBRAPA experts
The project will formulate a national strategy for agricultural innovation in addition to training some 60 researchers from Angola’s Agricultural Research Institute and 45 from its Veterinary Research Institute
said the project would contribute to national efforts on food security and poverty reduction which have already enabled Angola to meet the Millennium Development Goal target of halving its proportion of hungry people ahead of the 2015 deadline
quoted a message by former Brazilian President Luiz Inácio Lula da Silva to Angolan President José Eduardo Dos Santos: “The similarity between Africa’s Savanna and the Brazilian Cerrado presents tremendous potential for EMBRAPA’s intervention in the African continent
Brazil would like to help Angola in diversifying and realizing its immense economic and agricultural potential and securing its food self-sovereignty.”

This article is part of the Research TopicPrevention and Control of Human T Lymphotropic Viruses 1 and 2 (HTLV-1/2)View all 32 articles
Human Immunodeficiency Virus (HIV) and Human T-Leukemia Virus (HTLV) are retroviruses that share similar routes of transmission
the prevalence of HIV and HTLV varies according to geographic region
is considered endemic for both retroviruses
The present study aimed to characterize the frequency of HIV/HTLV coinfection and evaluate the geographic distribution of coinfection throughout the state
This cross-sectional study was conducted at the state's Central Laboratory of Public Health (LACEN-BA) and included all samples from 2004 to 2013 submitted to serological testing for anti-HIV and anti-HTLV-1/2
screened by chemiluminescence/ELISA and confirmed by Western blot
Infection rates are expressed as the number of infected individuals per 100,000 inhabitants from each municipality
A total of 129,158 samples originating from 358/417 (85.8%) municipalities in Bahia were evaluated
HTLV was detected in 2.4% of the HIV-positive samples (n = 42) compared to 0.5% of those with negative HIV serology (n = 677) (OR: 4.65; CI: 3.39–6.37)
HIV/HTLV coinfection was more frequent in women (69.0%); the median age of coinfected individuals was 47.2 years [interquartile range (IQR): 41.6–55.4 years]
In the 14/417 (3.4%) municipalities where at least one case of HIV/HTLV coinfection was detected
the overall HTLV coinfection rate in HIV-positive samples was 0.25 (range: 0.17–13.84) per 100,000 inhabitants
Most cases of HIV/HTLV-1 coinfection (21/37
57%) were concentrated in the municipality of Salvador
Isolated instances (one or two cases) of HIV/HTLV-1 coinfection were distributed across municipalities known to be endemic for HTLV infection
In Brazil, the prevalence of HIV and HTLV vary according to geographic region, with higher rates of HIV found in the Southeast and South regions, while HTLV is more frequently detected in the North and Northeast regions (8, 9). Studies evaluating HTLV in HIV-infected populations from several regions of Brazil have demonstrated a prevalence varying from 1.5 to 10.9% (10–16)
In Salvador, the capital of the state of Bahia, located in northeastern Brazil, the prevalence of HIV and HTLV-1 in the general population have been estimated at 0.55 and 1.8%, respectively (20, 21)
Since Bahia is considered endemic for both retroviruses
the present study aimed to better characterize the frequency of HIV/HTLV coinfection and evaluate the geographic distribution of coinfection throughout the state of Bahia
This study received ethical approval from the Institutional Review Board (IRB) for Human Research at the Goncalo Moniz Institute
Bahia-Brazil (CAAE number 22478813.7.0000.0040)
All identifiable patient information was anonymized to maintain confidentiality
thereby avoiding the need for individual verbal or written consent
A cross-sectional study was conducted using data obtained from the Central Laboratory of Public Health of Bahia (LACEN-BA)
responsible for infectious disease surveillance via laboratory analysis throughout the state
This laboratory's target population is mainly comprised of blood donors
pregnant women and individuals exhibiting symptoms of infectious disease
whose blood samples are referred by blood banks

Profile of HTLV/HIV coinfection in municipalities throughout Bahia
Distribution of HIV/HTLV coinfection according to age among 29 females and 13 males in Bahia
In the 42 cases of coinfection, WB identified 37 (75.5%) samples as positive for HTLV-1 (prevalence ~0.03%), 3 (6.1%) for HTLV-2 (prevalence ~0.002%) and 2 (4.1%) were positive for both HTLV-1 and HTLV-2 (prevalence ~0.002%) (Figure 2)
Considering those individuals who tested negative for HIV but were positive for HTLV (n = 677)
617 of these samples were positive for HTLV-1 (91.1%)
24 for HTLV-2 (3.6%) and 36 (5.3%) were positive for both HTLV-1 and HTLV-2
Out of 417 municipalities in the state of Bahia, 358 (85.8%) sent samples to LACEN at some time during the study period. At least one case of HIV was reported in 155 (37.2%) municipalities, while HTLV-1, HTLV-2 and HTLV-1/2 coinfection were detected in 121 (29.0%), 13 (3.1%) and one (0.2%) of the municipalities, respectively (Figure 4)
concentrated mainly in the Salvador (n = 21)
Figure 5. Geographic distribution of cases of HIV/HTLV-1, HIV/HTLV-2, and HIV/HTLV-1/2 coinfection among municipalities in the state of Bahia (2004–2013). Microregions are delimited by gray lines. Public domain digital maps were obtained in shapefile format (.shp), subsequently reformatted and analyzed using QGIS version 3.10 (Geographic Information System, Open-Source Geospatial Foundation Project. http://qgis.osgeo.org)
The global rate of HIV/HTLV-2 coinfection was estimated at 0.02 per 100,000 inhabitants (range: 0.07–4.80/100,000 inhabitants) and identified in two municipalities: one case in Paramirim (4.80 cases per 100.000 inhabitants) and two cases in Salvador (0.07 case per 100.000 inhabitants) (Table 1; Figure 5)
The two cases of triple infection were found in the Salvador microregion (0.07 cases per 100,000 inhabitants) (Table 1; Figure 5)
The overall rate of HIV/HTLV-1/HTLV-2 co-infection was estimated at 0.01 per 100,000 inhabitants
The main limitation of the present study was the use of non-random sampling
which resulted in a predominance of females
serological HTLV screening for pregnant women was become compulsory in 2011
which surely contributed to a higher proportion of women in the samples analyzed
gender imbalance may have impacted the higher frequency of HIV/HTLV coinfection in women observed herein
Another limitation was the absence of information collected on risk factors for HIV/HTLV coinfection
with respect to the representativeness of the municipalities
~86% of the state municipalities were evaluated throughout the study
detected in just 2.4% of all HIV-infected individuals evaluated and in 3.4% of the municipalities throughout the state
The areas with higher numbers of coinfection cases were those considered hotpots for HTLV and HIV
representing important economic or tourist centers in the state
The identification of relevant risk factors associated with HTLV/HIV coinfection can lead to efficacious actions in a variety of epidemiological contexts specific to each affected region
It is our hope that these findings will provide support for the implementation of preventive measures to contain the spread of these viruses
especially in areas where higher rates of HTLV/HIV coinfection were described

Salvador, Bahia (northeastern Brazil), has been identified as the epicenter of Human T-cell leukemia virus Human T-cell leukemia virus (HTLV) type 1 infection in the country. This study aims to estimate the rate of HTLV infection and the geographical distribution of this virus in this state.
All HTLV tests (chemiluminescence/ELISA assays/Western Blotting) performed in the Central Laboratory of Public Health of Bahia (LACEN) from 2004 to 2013 were included. Data was extracted from LACEN’s database using high volume extract, transformation and load throughput. Infection rate was expressed as the number of infected individuals per 100,000 inhabitants considering municipalities grouped in microregions and/or mesoregions as the unit of analysis.
HTLV infection is disseminated in the state of Bahia, with an overall moderate rate of infection. Further studies should be conducted to characterize the epidemiological and clinical profile of HTLV-infected individuals better and to propose effective prevention measures.

has been identified as the epicenter of Human T-cell leukemia virus Human T-cell leukemia virus (HTLV) type 1 infection in the country
This study aims to estimate the rate of HTLV infection and the geographical distribution of this virus in this state
Methods: All HTLV tests (chemiluminescence/ELISA assays/Western Blotting) performed in the Central Laboratory of Public Health of Bahia (LACEN) from 2004 to 2013 were included
Data was extracted from LACEN’s database using high volume extract
Infection rate was expressed as the number of infected individuals per 100,000 inhabitants considering municipalities grouped in microregions and/or mesoregions as the unit of analysis
Results: A total of 233,876 individuals were evaluated
Individuals were from 394 out of 417 municipalities of Bahia (94.5%)
HTLV chemiluminescence/ELISA assay was found to be reactive for 3,138 individuals from whom 2,323 had WB results (1,978 positives
58 (2.9%) for HTLV-2 and 107 (5.4%) were for both HTLV-1 and HTLV-2
The cumulative mean rate of HTLV-positive cases in Bahia was 14.4 per 100,000 inhabitants
Three microregions presented rates >20 HTLV-positive cases/100,000 inhabitants: Barreiras (24.83 cases per 100,000 inhabitants)
Salvador (22.90 cases per 100,000 inhabitants)
and Ilhéus-Itabuna (22.60 cases per 100,000 inhabitants)
Conclusion: HTLV infection is disseminated in the state of Bahia
with an overall moderate rate of infection
Further studies should be conducted to characterize the epidemiological and clinical profile of HTLV-infected individuals better and to propose effective prevention measures
The present study aimed to estimate the seroprevalence and geographical distribution of HTLV infection in the state of Bahia over a 10-year period (2004–2013)
All available serological tests for HTLV- 1/2 were evaluated using the database of the Bahia state public health reference laboratory
which tests blood samples from all municipalities in the state
The Institutional Review Board (IRB) for Human Research at the Gonçalo Moniz Institute of the Oswaldo Cruz Foundation (Salvador
Brazil) provided ethical approval to conduct this study (CAAE number 22478813.7.0000.0040)
Illustration of the state of Bahia’s seven mesoregions and 32 microregions
grouped by IBGE to more accurately reflect economic and social similarities among this state’s municipalities
A retrospective ecological study was conducted using data obtained from the Central Laboratory of Public Health of Bahia (LACEN-BA)
which is responsible for infectious disease surveillance throughout the state via laboratory analysis
The target population was comprised mainly of blood donors
prenatal physicians or clinicians in the public health system
All serological tests for HTLV were included among the 32 Bahia microregions from 2004 to 2013
testing was carried out by ELISA using the Murex HTLV-1/2 immunoassay (DiaSorin S.p.A.
from 2009 to 2010 using the anti-HTLV-1/2 Sym Solution kit (Symbiosis Diagnostica LTDA
the CLIA chemiluminescence assay (Architect rHTLV-1/2
Singapore) was used throughout the study period for confirmation
HTLV-negative samples were defined as lack of reactivity to HTLV-specific proteins; HTLV-1-positive samples were defined as reactive to GAG (p19 with or without p24) and two ENV (GD21 and rgp46-I) proteins; HTLV-2-positive samples were those reactive to GAG (p24 with or without p19) and two ENV (GD21 and rgp46-II) proteins; HTLV seropositive samples were defined as samples reactive to GAG (p19 and p24) and ENV (GD21)
The samples that indicated co-infection of HTLV -1/2 demonstrated reactivity for specific markers of both HTLV-I and HTLV-II: GD21
Samples were considered indeterminate when no specific bands for HTLV-I
All serological tests for HTLV that lacked confirmatory results were excluded
Spatial distribution maps based on moving averages were constructed by applying 3-year intervals to data from 2004 to 2013
This method was also used to minimize the effects of random fluctuation for a time-series of infection rates calculated for rare events
Annual incidence rates were calculated for each of the 32 micro-regions and the entire state using standardized methods
To assess the relative risk of HTLV in each microregion
maps were constructed using the moving average for the first 3-year rate in Bahia as the denominator assuming no changes in time and space
A total of 249,869 serologies for HTLV were performed during the studied period. Due to multiplicity (i.e., the presence of multiple serological test results in the database for a given individual), 15,993 samples were excluded (Figure 2)
The final sample comprised 233,876 serological tests from unique individuals
the 2,323 samples submitted to Western blotting produced 1,978 positive (85.2%) 63 negative (2.7%) and 282 (12.1%) indeterminate results
815 samples were not submitted to Western Blot due to a lack of reagents at some points during the study period
Assuming that 85.2% of these 815 samples Blot would have been HTLV positive
it follows that the overall prevalence of HTLV would have been 1.18%

Boxes with dotted lines indicate samples excluded from the study
An overall increase in the number of positive cases was observed in all microregions
as evidenced by the first 5 years of study (2004–2008) in which 4.3 cases of HTLV per 100,000 inhabitants was found
compared to 10.5 cases per 100,000 inhabitants during the final period (2009–2013)
Spatiotemporal distribution of HTLV positivity in the State of Bahia from 2004 to 2013
calculated using 3-year moving averages considering the state’s microregions as units of analysis
The cumulative mean rate of HTLV-positive cases in Bahia was 14.4 per 100,000 inhabitants. Considering the grouping of HTLV-positive samples into microregions (Figure 4)
three demonstrated rates above 20 HTLV-positive cases per 100,000 inhabitants: Barreiras (24.83 cases per 100,000 inhabitants)
Elevated rates of HTLV infection ranging from 8.96 to 19.30 cases per 100,000 inhabitants were also seen in nine other microregions
a homogenous distribution of HTLV positivity was observed
No information was retrieved from two microregions (Santa Maria da Vitória and Jeremoabo)
and HTLV-1/2 positivity in the State of Bahia from 2004 to 2013
considering microregions as the unit of analysis
The 12 microregions with the highest rates of HTLV positivity per 100,000 inhabitants are highlighted
in addition to the top five according to each respective HTLV type
The microregions of Barreiras, Salvador and Porto Seguro were all notable for high rates of HTLV-1 and HTLV-2 infection, as well as HTLV-1/2 coinfection. HTLV-1 was also predominant in Ihéus-Itabuna and Itapetinga microregions. Higher rates of HTLV-2 infection were also found in the Livramento do Brumado and Juazeiro microregions. HTLV-1/2 coinfection was most prevalent in the Entre Rios and Valença microregions (Figure 4)
The median age of the studied population was 31 years (interquartile range: 25–39 years) and the female:male ratio was 8:1. The median age of HTLV-infected persons was 46 years (IQR: 33–59 years), and 75% were women. Overall, our analysis of HTLV-positivity according to age and sex showed much higher frequencies in individuals aged 31 years or older for both males (85.7%) and females (79.3%) (Figure 5)
Our stratified age analysis identified 42 positive individuals aged 15 years or younger from all of the mesoregions
The highest frequency of this age group was found in Nordeste Baiano
Distribution of HTLV-positive cases throughout the mesoregions of the State of Bahia
stratified according to sex and age (2004–2013)
higher frequencies of positive cases were observed among females aged 15–30 years as compared to males
a higher frequency of positive cases among males aged >30 years was found in the Vale do São Francisco da Bahia mesoregion
no information on the number of HTLV-infected individuals in the State of Bahia (the fourth-most populous in Brazil)
nor the geographical distribution of these individuals
The present results demonstrate that HTLV infection is indeed widespread throughout the state
with an overall rate of 14.4 per 100,000 inhabitants
followed by HTLV-1/HTLV-2 coinfection (5.4%) and HTLV-2 (2.9%)
The Ilhéus-Itabuna microregion is located around the southern coastal region of Bahia
having a humid tropical climate with areas of Atlantic Forest
This regional center is home to important commercial
The economic importance of this region grew during the golden era of cocoa production
the economy is based on tourism and other activities related to the seaport
the Jacobina microregion has a tropical climate with a dry season
rivers and waterfalls favor ecological tourism
to the best of our knowledge no previous studies reported this area being endemic to HTLV infection
We cannot exclude the possibility that these microregions received samples from surrounding areas
Barreiras is the most important municipality located in the microregion
This microregion has a tropical climate and the predominant vegetation is the arboreal cerrado
The regional economy is mainly based on agribusiness
and migrants from all over Brazil moved here in the 1970s and 1980s
It is possible that HTLV-1/2 coinfection found in Bahia may result from the introduction of drug users infected with HTLV-2 into areas in which HTLV-1 is already prevalent
a progressive increase in the incidence of HTLV infection was observed throughout the study period
This is likely due to an expansion in the number of municipal primary health clinics provided by the federal Family Health Program
as well as increases in testing and counseling centers (aimed primarily at sexually transmitted diseases) in the countryside of the state
awareness surrounding HTLV infection increased during the study period and HTLV was included on the list of compulsory disease notifications for the state of Bahia in 2011
It is also possible that compulsory serological HTLV screening for pregnant women
contributed to the higher proportion of women detected in this age range
In the present study the HTLV infection was observed in 42 individuals under 15 years
indicating that in addition to sexual transmission
the vertical route may be an important route

With respect to the representative map of individual identifying as “black,” bars represent the number of quilombola communities located in each mesoregion of the state (total number = 656)
the present study is unable to offer any insight into virus phylogeny
as the retrospective nature of this investigation precluded the performance of molecular analysis to accurately assess results considered indeterminate by Western Blot
the present study serves to highlight previously unreported data regarding clusters of HTLV infection throughout the state of Bahia
which is considered to be the Brazilian state with the highest HTLV infection rate
HTLV infection cannot be considered as restricted to the area of Salvador
as the data reported herein identified new endemic areas
Considering the overall prevalence of HTLV in Bahia to be 0.84% (1,978/233,876)
it follows that ∼130,000 individuals would be infected with HTLV
it is important to note that this number could be underestimated
since 26% of the HTLV reactive samples were not submitted to Western blotting
the overall prevalence would increase to 1.18%
Further studies are needed to better describe the epidemiological profile of the infected population and to reinforce public policies designed to prevent HTLV transmission
As the present study has a retrospective design
evaluating HTLV serologies performed in a 10 years-period in the Public Health Laboratory of Bahia
the Institutional Research Board of Fiocruz approved a study

Infectious Diseases: Epidemiology and Prevention
Volume 10 - 2022 | https://doi.org/10.3389/fpubh.2022.963790
Hemophilia is a recessive genetic disease caused by a mutation on the X chromosome that has been linked to a high risk of transfusion-transmitted infections
especially sexually transmitted infections
The purpose of this retrospective study was to characterize the clinical and epidemiological profile and describe the prevalence of sexually transmitted viral infections in patients with hemophilia in the Northern Brazilian state of Amazonas
laboratory and sociodemographic data of hemophiliac patients (n = 311) for the period 2011–2019
The majority of the study population was composed of people with a low level of education aged 21–30 years old
and HTLV-1/2 infections among the study population were 10.52
No HIV infection was found among the patients
Between 2011 and 2015 the prevalence of HCV increased by over 100% and the incidence peaked in 2013
The severe hemophilia was associated with the presence of inhibitor factor (Odds Ratio [OD] 9.83; 95% IC: 3.41–27.62
p < 0.0001) or target joint (OD 6.59; 95% IC: 3.27–13.34
The presence of inhibitor was positive and significantly correlated with HCV infection (r = 1.00
Our results showed that HCV infection is highly prevalent in patients with hemophilia and might be involved in the development of inhibitors
these data provide new insights into the clinical and epidemiological profile of patients suffering from hemophilia in the Northern Brazilian state of Amazonas
The Amazonas is the largest state in Brazil, composed of 62 municipalities, with an estimated population of 4 million people (14)
Around 311 patients live with hemophilia in the Amazonas according to the Hematology and Hemotherapy Foundation of Amazonas (HEMOAM)
the clinical epidemiological profile of these patients is unknown
the purpose of this study was to describe the clinical and epidemiological characteristics and the prevalence of sexually transmitted viral infections in patients living with hemophilia in the Brazilian state of Amazonas
This study was approved by the Human Research Ethics Committee of the Hematology and Hemotherapy Hospital Foundation of Amazonas (approval number: 3.328.121)
Confidentiality was assured to all participants
All analyses were performed following relevant guidelines and regulations
This was an observational retrospective study conducted with hemophiliac patients treated at the Hospital Foundation of Hematology and Hemotherapy of Amazonas (HEMOAM)
A total of 311 patients with a previous diagnosis of hemophilia A (n = 274) and B (n = 37) were included
Clinical and socio-demographic information was collected from the hospital's electronic databases
The study population was comprised of patients of either sex and different ethnicities who were aged from 1 to 92 years old
To obtain the clinical data related to viral infections
the patient's clinical records related to the 2011–2019 period were acquired from the Hemovida Web Coagulopathies system
The following information was collected from June 2019 to March 2020: date of birth
Patients with incomplete clinical data were excluded from the study
Descriptive analysis was used to evaluate the total number of patients according to sociodemographic information and the prevalence of viral infections
Prevalence ratio (PR) was used for associations between hemophilia and viral prevalence rates
while the Odds ratio (OR) analysis was used for the associations between the severity of hemophilia and the presence of inhibitor or target joint
OR and PR analyses were done through the chi-square test and Yate's correction with a 95% confidence interval (CI) calculated by the method Koopman asymptotic score and Baptista-Pike
Spearman's test was applied to assess the correlation between disease severity and the presence of inhibitor
The correlation was considered strongly positive when r > 0.7 All analyzes were performed using the GraphPad Prism v8.0.1 software and values p < 0.05 were considered significant
Sociodemographic profile of hemophiliac patients
The state of Amazonas consists of 62 municipalities. The study population comprises patients of 21 municipalities, the majority (65%) living in the city of Manaus, the capital of the state of Amazonas. The remaining 35% of the study population resides in small towns situated in the countryside of the state. Jutaí (n = 13) and Tefé (n = 11) were the municipalities in the countryside with the highest number of hemophiliac patients (Figure 1)
No residency information was found for 24 patients
Site map showing the distribution of hemophiliac patients per location within the state of Amazonas
The map was built using the WGS1984 datum (worldclim software v.2.0)
Only 190 patients had the laboratory records available. Overall, the prevalence of blood-borne viruses was 12.10% (n = 23). The majority of those infected were men aged 31–40 years old (n = 22) (Figure 2A). Only one woman showed seropositivity for HCV infection, which was the most widespread viral infection (10.45%) in the study population (Supplementary Table 1)
Two patients showed seropositivity for HTLV-1/2 (1.05%) and only one patient (0.52%) was positive for HBV infection (laboratory results were positive for anti-HBsAg
No HIV infection was found in the study population
Prevalence and incidence rates of viral infections in patients with hemophilia
(A) Numbers of viral infections according to age and sex
and HBV and (C) incidence coefficient of HCV infection according to age
Next, we evaluated viral infection prevalence rates from 2011 to 2019 (2020 and 2021 data were not yet available, likely as a result of the coronavirus pandemic). Prevalence rates of HCV infection rose by over 100% between 2011 and 2015, after stabilizing through 2019 (Figure 2B). When we looked at the HCV incidence during the same period, the incidence coefficient (per 100 patients) ranged from 0.68 to 1.28% (Figure 2C)
The incidence of HCV infection peaked in 2013
The bivariate analysis carried out to check the correlation between severity, HCV infection, inhibitor and target joint showed that all factors are highly and positively correlated (Figure 3)
only the correlation between HCV infection and the presence of autoantibodies was statistically significant (r = 1.00
the presence of HCV infection may be a predisposing factor for the development of inhibitors in the context of hemophilia
Pearson's correlation between HCV infection
Values of r > 0.7 were considered strong positive
***p < 0.0001
Association between presence of comorbidities and severity of hemophilia
Treatment adherence is a big challenge in the Amazonas state since hemophilia treatment centers exist only in the capital of Amazonas and the majority of small towns in the countryside are at a great distance from Manaus (17)
long river travel is the only means of transportation available to access health services
35% of the study population is from hard-to-reach cities
which can undermine the treatment and medical support
This situation may put these patients at high risk of acquiring infectious diseases and developing hemophilia-related comorbidities
we found no significant association between these factors and the increase of susceptibility to infectious diseases or the development of comorbidities
Our findings also suggest an association between HCV infection and the development of inhibitors
we found that the presence of inhibitor and joint target were directly associated with the severity of hemophilia
The factors associated with the presence or development of these comorbidities need further investigation to improve the clinical management of the hemophiliac patient
Our study showed that the prevalence of HTLV-1/2 (1.14%) in the study population is higher than in the Brazilian population in general
These data indicate that the susceptibility to acquiring HTLV-1/2 infection may be increased in the study population
additional studies are required to better clarify the epidemiological aspects of HTLV-1/2 infection among hemophiliac patients in the State of Amazonas
Although our results propose new data regarding viral infections in hemophiliacs in Amazonas, with results never described before, we understand the limitations of our study, such as the lack of updated epidemiological data, which makes it difficult to obtain complete data. New computer systems have been proposed to organize the sociodemographic data of all patients, especially hemophiliacs (38)
The prevalence of HCV and HTLV 1/2 is still above the national average
and further epidemiological studies are needed with a focus on this population to better understand the clinical aspects
Our results demonstrate that some infectious diseases have high prevalence rates
the absence of routine serological tests is still frequent in the hemophiliac population
Hemophiliac patients in Amazonas have higher prevalence rates for HCV and HTLV 1/2
which reveals the need for further studies to provide a better assessment of the hemophiliac population
This study improves the current knowledge on hemophilia epidemiology in the Amazon region
which is important to evaluate factors that can influence the disease prognosis
our findings may help the patient clinical management at the individual and collective levels
Limitations in this study included the use of secondary data
the possibility of underreporting infections and incorrect records
The quality of monitoring systems varies between regions in Brazil and can have a direct impact on data quality
underreporting is most pronounced in more vulnerable areas where the access to health services is lower
another limitation is that the diagnosis of HCV is not categorized in the system by the method (serologic or molecular)
which makes no distinction between active infections and previous infections
this study demonstrated that HCV infection is widespread and could be involved in the induction of inhibitor development in hemophiliac patients of the Amazonas state
The presence of inhibitor or target joints is associated with hemophilia severity
Our findings also draw attention to the specific characteristics of the Amazonian region such as the socio-economic status of the population and the difficulty to reach places
which could impact the treatment adherence and prognosis of hemophilia
Our results enhance the current knowledge on the epidemiology of hemophilia
which is important for assessing factors that may influence the disease's prognosis and may help the clinical management of patients both individually and collectively

Food BioscienceCitation Excerpt :Table 2 highlights some recombinant lipases approved by the FDA with GRAS (Substances Generally Recognized as Safe) status for use in the food industry
(2020) used several techniques simultaneously to produce and use lipase
the use of agro-industrial residues and enzyme immobilization
The lipase 1 from Beauveria bassiana was efficiently expressed in Aspergillus nidulans A773
Process BiochemistryCitation Excerpt :Analysis of the first temporal range (2000–2009
6a) revealed that studies were highly associated with lipase-catalyzed esterification [97,98] and transesterification [99–102] reactions as well as lipase regioselectivity and enantioselectivity
We highlight that research on lipase immobilization and biodiesel production began to emerge strongly in this time range [23,103–105]
This finding corroborates the trends in biodiesel research (Fig
Supplementary Material) and worldwide biodiesel production
which intensified significantly after 2007
according to data from the Organization for Economic Cooperation and Development of the United Nations Food and Agricultural Organization [106]
these 4.40 – 4.65 million tonnes of SCG waste can be recovered and tapped as valuable feedstock for various applications
Owing to SCG’s unique physicochemical properties such as rich with fatty acids
SCG has been successfully utilised in biodiesel productions [24,25]
adsorbents [30–32] and fine chemical productions [33]
With the current food waste problems associated with SCG
the utilisation of SCG as feedstock for solid biofuel production is an attractive way to reduce waste generation through valorisation as well as to generate potential products for energy sectors
Journal of Cleaner ProductionCitation Excerpt :Several peaks at 1032 cm−1 (C–O stretching)
and 1245 cm−1 (C–O stretching) were attributed to a great variety of monosaccharides together with diverse acids molecules
pH value of SCGs was reported to be in the acidic range
which is expected to be typical for an agricultural product subject to the natural elements and grown in a variety of regions
Background: Trained subjects have difficulty in achieving continued results following years of training, and the manipulation of training variables through advanced resistance training (RT) methods is widely recommended to break through plateaus.
Objective: The purpose of the present study was to compare the acute effects of traditional RT (TRT) versus two types of sarcoplasma stimulating training (SST) methods on total training volume (TTV), lactate, and muscle thickness (MT).
Methods: Twelve trained males (20.75 ± 2.3 years; 1.76 ± 0.14 meters; body mass = 79.41 ± 4.6 kg; RT experience = 4.1 ± 1.8 years) completed three RT protocols in a randomly sequenced order: TRT, SST contraction type (SST-CT), or SST rest interval variable (SST-RIV) with 7 days between trials in arm curl (elbow flexors) and triceps pulley extension (elbow extensors) performed on the same day.
Results: The SST groups displayed greater acute biceps and triceps brachii (TB) MT versus the TRT session, with no difference in lactate levels between them. The SST-CT resulted in greater biceps and TB MT versus the SST-RIV session. The TTV was greater for the TRT session versus the SST sessions, except in the case of the elbow flexors (no difference was observed between TRT and SST-CT), and higher for the SST-CT versus the SST-RIV.
Conclusion: Trained subjects may benefit from using the SST method as this method may offer a superior MT stimulus and reduced training time, even with a lower TTV.

The TTV was greater for the TRT session versus the SST sessions
except in the case of the elbow flexors (no difference was observed between TRT and SST-CT)
and higher for the SST-CT versus the SST-RIV
Conclusion: Trained subjects may benefit from using the SST method as this method may offer a superior MT stimulus and reduced training time
the comparison between advanced RT methods is scarce in literature
especially with regard to the most recent training approaches used in practice by bodybuilders and trained subjects; for example
the sarcoplasma stimulating training (SST) method
the aim of the present study was to compare the acute effects of traditional RT versus two types of the SST method on TTV
Our hypothesis was that the SST method would result in greater acute MT
and lower TTV as compared to traditional RT
subjects should be regularly performing all exercises utilized in the training intervention with a minimum frequency of once a week before entering the study
and should be performing RT a minimum of 3 days/week for at least 1 year at the University training facility
The range of RT experience was 2–8 years
Subjects with any existing musculoskeletal disorders
a history of injury with residual symptoms (pain
“giving-way” sensations) in the trunk
upper and lower limbs within the last year
and subjects who were taking anabolic steroids or any other illegal pharmacological agents known to increase muscle size at the time of selection and during the previous year
This study was approved by the university research ethics committee (protocol 1.792.429); all subjects read and signed an informed consent document
The 10RM tests were performed to determine the exact training load for standing arm curl (elbow flexors)
and triceps pulley extension (elbow extensors)
subjects were advised to start with their elbows fully extended and to then flex their elbows as much as possible
the elbows were positioned at a 90° angle and subjects were asked to fully extend their elbows
Ten minutes were allowed between the tests to avoid fatigue
The tests followed these procedures: warm-up on each exercise with 5–10 submaximal repetitions using a light load (60% of the estimated 10RM); 1-min rest
and load increments of 5–10% until the 10RM was found within 3–5 attempts
using 3- to 5-min rest intervals; subjects were instructed to lift and lower the load at a controlled velocity
approximately 2 s for each phase of the movement; 10 repetitions were recorded
with the maximal load determined by the last successful set of repetitions
Subjects were familiarized with both exercises in their training routines
and standardized instructions were provided
Consistent verbal encouragement was provided during the testing procedures to all subjects
All testing and training sessions were scheduled 7:00 PM in controlled room temperature
Subjects completed three RT protocols in a randomly sequenced order
as follows: traditional resistance training (TRT)
sarcoplasma stimulating training contraction type (SST-CT)
or sarcoplasma stimulating training rest interval variable (SST-RIV)
they were advised to refrain from any type of regular exercise training in the days between testing sessions
The chosen exercises were standing arm curl (elbow flexors)
and triceps pulley extension (elbow extensors) performed on the same day
Ten minutes of rest were allowed after the standing arm curl exercise before starting the triceps pulley extension exercise
The TRT session consisted of eight sets to failure (inability to complete a full concentric repetition with standardized movement technique) with a 10RM load and with 1 min rest intervals between them
The SST-CT session was as follows: an initial set with a 10RM load to failure
followed by two more sets with 20 s rest intervals while maintaining the load
and subjects performed another set with repetitions that consisted of a 1 s concentric phase and a 4 s eccentric phase to failure; after another 20 s
consisting of repetitions with a 4 s concentric phase and a 1 s eccentric phase to failure
an additional 20% of the load was removed and an isometric muscle action (static hold at 90° of elbow flexion) was held until failure
The SST-RIV consisted of an initial set with 10RM load to failure followed by programmed variable rest intervals between sets to failure without load reduction as follows: 45
Total training volume in arbitrary units (A.U.) for the standing biceps curl (elbow flexors), and triceps pulley extension (elbow extensors) was calculated by multiplying the total number of sets, the total number of repetitions, and the load used (kg) (American College of Sports Medicine, 2009)
All samples were obtained while subjects were seated
The right index finger was cleaned using alcohol prior to each blood draw; the first blood drop was discharged to avoid contamination of the sample
Blood samples of 25 μL were collected in heparinized capillary tubes and transferred to microtubes containing 50 μL of sodium fluoride at 1%
All samples were collected at the following time-points: pre-test
Lactate concentration was analyzed via an electro enzymatic method with a lactate analyzer (YSI 2300 Stat Analyzer; Yellow Springs Instruments
Of note was the fact that values from immediately post
and 10 min post were not statistically different
and they were collectively presented only as post-training
Ultrasound imaging was used to obtain measurements of MT and was performed by a trained technician using an A-mode ultrasound imaging unit (Bodymetrix Pro System; Intelametrix Inc.
Following the application of a water-soluble transmission gel (Mercur S.A
a 2.5-MHz linear probe was positioned perpendicularly to the tissue interface without depressing the skin
The equipment settings were optimized to obtain the best quality images according to the manufacturer’s user manual and were held at a constant across testing sessions
When the quality of the image was deemed to be satisfactory
and MT dimensions were determined by measuring the distance from the subcutaneous adipose tissue–muscle interface to the muscle-bone interface
Measurements were taken on the right side of the body for the triceps brachii (TB) and biceps brachii (BB)
Upper arm measurements were conducted while subjects were standing
measurements were taken at 60% distal between the lateral epicondyle of the humerus
the examined limb was held constant in the same position to avoid movement
To maintain consistency between pre- and post-intervention testing
To further ensure the accuracy of measurements
at least three images were obtained for each site
If measurements were within 1 mm of one another
the values were averaged to obtain a final value
If measurements were more than 1 mm of one another
and the closest three measurements were averaged
The test-retest intraclass correlation coefficient for TB and BB were 0.998 and 0.996
while the coefficient of variation was 0.6 and 0.4%
The standard error of the mean for these measures was 0.42 and 0.29 mm
The data are expressed as mean and standard deviation (SD) values
The Shapiro–Wilk test was applied to check for the normality distribution of the study variables
ANCOVA was used to determine the effect of three different exercise-training systems on post-intervention MT and blood lactate concentration after controlling for pre-intervention variables
One-way repeated measures ANOVA was also used to determine the differences between interventions for TTV
Tukey’s post hoc test with the Bonferroni correction was applied in the event of significance
The effect size calculation (ES = difference between pre- and post-intervention divided by the pooled SD) was used to evaluate the magnitude of the training effect
The level of significance was p ≤ 0.05 and SPSS version 20.0 (Somers
There was a statistically significant difference in TTV between the interventions [F(1,16) = 20.87, p = 0.002 for elbow flexors and F(1,16) = 15.98, p = 0.004 for elbow extensors]. The elbow flexors TTV during SST-CT was not significantly different (p = 1.000) from TRT, while the TTV during the SST-RIV was significantly less than SST-CT (p = 0.001) and TRT (p = 0.003; Table 1)
The elbow extensors TTV during TRT was significantly greater than SST-CT (p = 0.023) and SST-RIV (p = 0.007)
The TTV for the elbow extensors during SST-CT was also significantly greater (p = 0.024) than SST-RIV
Mean ± SD total training volume (TTV) of elbow flexors
and elbow extensors for sarcoplasma stimulating training contraction type (SST-CT)
and traditional resistance training (TRT) sessions
Arm MT pre- and post SST-CT, SST-RIV, and TRT sessions are shown in Figure 1
there was a statistically significant difference in post-intervention MT between the interventions [F(2,26) = 51.41
MT presented significant increases (p ≤ 0.05) following each intervention as follows: (SST-CT: 10.0 ± 1.3 mm for BB
and 10.9 ± 1.3 mm for TB; SST-RIV: 6.5 ± 0.7 mm for BB
and 6.7 ± 0.7 mm for TB; TRT: 5.1 ± 1.3 mm for BB
the SST-CT session presented significantly greater increases (p ≤ 0.05) in BB and TB MT versus the SST-RIV and TRT sessions
The SST-RIV session also presented significantly greater increases (p ≤ 0.05) in BB and TB MT versus the TRT session

Blood lactate concentration also presented significant increases (p ≤ 0.05) following all conditions (Table 2)
after adjustment for pre-intervention values
there were no significant differences versus post-exercise [F(2,26) = 0.48
and effect size (ES) of blood lactate pre and post sarcoplasma stimulating training contraction type (SST-CT)
The initial hypothesis of the present study was partially confirmed
as the SST sessions resulted in greater acute BB and TB MT versus the traditional RT session
while there was no difference in lactate levels between them
SST-CT also resulted in greater BB and TB MT versus the SST-RIV session
TTV was greater in the traditional RT session versus both SST sessions
for which the results were not statistically different between the TRT and SST-CT
The SST-CT resulted in greater TTV versus the SST-RIV for both exercises tested
this is the first paper to report and to compare the acute effects of variations of the SST method versus traditional RT
Marshall et al. (2012) examined well-trained subjects in performing the squat exercise at an intensity of 80% 1-RM with 5 sets of 4 repetitions and 3 min rest intervals between sets versus 5 sets of 4 repetitions with 20 s inter-set rest intervals or a rest-pause method with the first set to failure
and subsequent sets performed with a 20 s inter-set rest interval up to 20 repetitions
The rest-pause method resulted in greater electromyographic activity of several lower limb muscles versus the other training sessions
It is very difficult to compare previous studies with our results
as the proposed SST method is widely different from other traditional methods
while it seems that even trained subjects unaccustomed to performing a specific training approach with very short rest intervals will experience higher local metabolic stress
as observed with rest-pause and 3/7 methods
Total training volume, time under tension, and metabolic stress seem to be important variables to alter acute and chronic physiological responses to RT, albeit it is impossible to determine the most important of them. Valamatos et al. (2018) examined untrained subjects in performing leg extension training for 15 weeks; three sessions/week with partial (0–60° of knee flexion) and full range of motion (ROM) (0–100° of knee flexion)
and time under tension equated for both groups
The authors reported that the group performing the partial ROM training displayed joint angle-specific strength gains
with greater increases around the trained joint angles
and also similar gains in muscle hypertrophy
torque and total mechanical work were greater in the full ROM group
despite having the same time allocation under tension
while MT responses were higher for the SST sessions
These results may confirm the original name and idea of the method proposed by Patrick Tuor
Some limitations of the present study include the lack of measures from muscle activation
and muscle strength before and after the training sessions that could supply valuable information about the physiological stress imposed by the SST method
The well-trained characteristic of the studied subjects
and the strong control of training variables increase the validity of the present results
Highly trained subjects may benefit from changing their RT routines by using the SST method
as this method may offer a superior MT stimulus
even with a lower TTV versus a more traditional approach
the chronic effects of the SST method on muscle hypertrophy and muscle strength remain to be determined
This is the first study ever to offer some interesting physiological insights about SST
a widely used method among trained subjects and bodybuilders
the question remains if the differences observed between SST approaches will result in distinct chronic adaptations

Starting in 1972, I remember going to Monte Park every Saturday morning at 9 a.m. to watch the best basketball talent in the area. I remember Manuel Costa giving basketball clinics on the fundamentals of the game. I also remember Peter Britto starting the basketball shootouts where teams from all over came to participate. If anybody was anybody, they had to go through Monte Playground. There have been so many great players, beginning in the 1970s that I have decided to give my own perspective.
I'm sure that I did not mention somebody who probably belongs on the list, but that's a testament to how many great players have come out of our local area. The list could probably go on and on, but I just wanted to bring to light some of the memories of Big Time Basketball in the New Bedford area.

Gossypol is a terpene-polyphenolic compound specific to cotton plants
monogastric livestock show greater sensitivity to this metabolite than ruminants
The aim of this investigation was to evaluate the toxicological effects of gossypol-containing and biodetoxified cottonseed-cake on hepatic function in rats
Biodetoxification of cottonseed cake was performed by the macrofungi Fistulina hepatica BRM 047114 and Pleurotus ostreatus BRM 055505 in a solid-state cultivation process
A toxicological study was performed using albino Wistar rat males (Rattus norvergicus)
A feed assay was conducted using the macrofungi cultivated on cottonseed cake (5%
serum biochemical analyses and histopathology were evaluated
For biodetoxified cottonseed cake treatments with both macrofungi
concentrations of feed up to 15% resulted in animal development similar to that of the untreated group
Histopathological analysis after feeding with biodetoxified cottonseed cake presented an unaltered cordonal arrangement
the group fed with cottonseed cake biodetoxified using F
hepatica BRM 047114 showed discrete inflammatory infiltrate
ostreatus BRM 055505 resulted in efficient reduction in toxic effects of free gossypol
and a reduction in circulating cholesterol levels
hepatica were able to minimize the toxic effects of free gossypol in rat diets
representing an important contribution for feed-formulation development for non-ruminants
Gossypium sp. are oilseed plants that generate biomass residue with significant levels of edible oil, crude protein, and diverse biomolecules appropriate for animal nutrition. The application of cottonseed cake, a by-product of cottonseed processing, as a potential nutrient source for animal feed is limited due to the presence of high concentrations of gossypol (Mane et al., 2007)
The gossypol molecule (C30H30O8) is a terpenopolyphenol secondary metabolite toxin that naturally plays a role in plant defense responses in cotton to predators (insect herbivores and nematodes) and occurs throughout the plant tissues (seeds
Considered an anti-nutritional factor, monogastric livestock shows greater sensitivity to this metabolite than ruminants, with diets containing gossypol leading to systemic adverse effects that include, among others, immunosuppression, weight loss, weakness, male and female reproductive impairment, liver damage, respiratory problems, heart failure and death (Fonseca et al., 2013; Câmara et al., 2015)
The macrofungi genera of Pleurotus and Fistulina, utilized in both food and medicine purposes, stand out among fungi capable of nutraceutically enhancing residual biomass. Depending on the substrate, they exhibit a high daily growth rate with efficient conversion of proteins and β-glucans, making them suitable for animal feed (Conceição et al., 2022)
This study was performed to evaluate the potential toxic effects on Wistar rat hepatic tissues following the intake of formulated feed
contrasting the presence of untreated and macrofungal-treated cottonseed cake
Agro-industrial biomasses employed in substrate formulations
oil palm mesocarp fiber (Elaeis guineensis) and sugarcane bagasse (Saccharum sp.)
were obtained from the raw material stock collection of lignocellulosic biomasses at Embrapa Agroenergy
The fungal strains Fistulina hepatica BRM 047114 and Pleurotus ostreatus BRM 055505 were obtained from the Collection of Microorganisms and Microalgae Applied to Agroenergy and Biotechnology (CMMAABio) at Embrapa Agroenergy. These were selected on the basis of previous results highlighting their potential in the biodetoxification of cottonseed (Conceição et al., 2018)
a total of 70 g (dry matter) of cottonseed cake
previously moistened to 60% with distilled water
was autoclaved at 121°C for 15 min (physical treatment)
The substrate was then inoculated with five 15 mm diameter mycelial plugs of F
previously grown for seven days on potato dextrose agar (PDA)
Solid-state cultivation cultures were then incubated for 20 days at 28°C for subsequent FG degradation analysis
In order to obtain optimal biomass combinations for both fungal growth and productivity (mushroom production) for the selected fungi
70% cottonseed cake was included in the substrate together with the addition of a 30% portion of one of the following agroindustrial residue biomasses: T1: eucalyptus sawdust; T2: sugarcane bagasse; T3: palm oil fruit pressing fiber; T4: elephant grass
The moisture content of all substrates was adjusted to 70%
Approximately 2.00 ± 0.02 kg of each substrate formulation was distributed into High Density Polyethylene bags (HDPE) containing sterile air exchange filters
Bags containing the substrates were then autoclaved at 121°C for 90 min
substrates were inoculated after cooling with 10 g of spawn (mycelial mass) of each fungal strain grown previously on brown rice substrate
bags were maintained at 26°C ± 2 and 70% humidity
After 34 days cultivation and complete mycelial colonization of the substrates
blocks were transferred to a mushroom-fructification room
with humidity maintained between 80% to 90% until fruiting
Mushroom fructification was observed only for P
biological efficiency (BE) and productivity (P) were evaluated according to the following equations:
The basic diet employed for feeding was a commercial formulation containing ground whole corn
vitamin premix (Vitamin A 12,000.00 IU; Vitamin D3 1,800.00 IU; Vitamin E 30.00 mg; Vitamin K3 3.00 mg; Vitamin B1 5.00 mg; Vitamin B2 6.00 mg; Vitamin B6 7.00 mg; Vitamin B12 20.00 mcg; Niacin 60.00 mg; Pantothenic Acid 20.00 mg; Folic Acid 1.00 mg
Biotin 0.05 mg; Choline 600.00 mg) minerals (Iron 50.00 mg; Zinc 60.00 mg; Copper 10.00 mg; Iodine 2.00 mg; Manganese 60.00 mg; Selenium 0.05 mg; Cobalt 1.50 mg.) and amino acids (Lysine 100.00 mg; Methionine 300.00 mg) (Labina Purina Ltd)
Diets employed for cottonseed cake tolerance assays were prepared with different inclusion levels of biodetoxified cottonseed cake (5
Control diets were set up using the same levels of untreated cottonseed cake
Two colonized substrates were selected for tolerance assays based on lowest achievable levels of FG obtained following cultivation and efficiency analysis of fungal cultivation: 1) cottonseed cake biodetoxified by P
ostreatus (from spent mushroom substrate (SMS)) following colonization of cottonseed cake (70%) plus eucalyptus sawdust (30%) over a 34 day period
plus a further 30 days for fruiting and mushroom harvesting; 2) cottonseed cake biodetoxified by F
hepatica following colonization of cottonseed cake (70%) plus sugarcane bagasse (30%) over a 34 day period
Both samples were dried for 48 h at 65°C
powdered with a knife mill (0.5 mm sieve) and maintained at -20°C for further analysis
Pelletized diets were oven dried at 65°C for 12 h and subsequently stored in plastic containers at 4°C to ensure quality throughout the study
Forty randomly selected rats were allocated into four equally sized groups
which comprised three different levels of cottonseed cake (5
and 25%) and one control group (commercial diet)
Seventy male Wistar rats were employed in different groups
Diets were prepared using three different levels of biodetoxified cottonseed cake: i) experimental groups with 5
and 25% of spent mushroom substrate (SMS) following growth of P
and 25% of colonized substrate following growth of F
hepatica; and one control group (commercial diet)
Bromatological analyses were performed on toxic cottonseed cake and biodetoxified cottonseed cake commercial diets, as well as on formulated diets. Moisture, crude protein, ethereal extract, and ash (mineral matter) content were determined according to the methodology described by the Association of Official Analytical Chemists (AOAC, 2000)
FG content in all samples was analyzed by High Performance Liquid Chromatography (HPLC), according to Conceição et al. (2018)
Components were separated using a C18 reverse phase Kinetex column (100 x 2.10 mm
with a methanol-0.1% TFA aqueous solution employed as mobile phase
Rats were monitored daily for clinical signs of toxicity (piloerection
and death) and for behavioral changes (irritability and aggressiveness)
a predetermined amount of feed was provided to the animals daily ad libitum
The remaining portion was then weighed to calculate the amount ingested each time new feed was provided
Water was also provided ad libitum to the animals without measurement
Feed intake was monitored throughout the entire experimental period to enable calculation of average daily intake
Animal growth was evaluated on the basis of the parameters of final weight
animals were anesthetized with ketamine and xylazine (i.p
Blood was collected by cardiac puncture and centrifuged (5 min
then plasma was aliquoted and stored at −80°C for analysis
Livers were dissected and weighed for calculation of the hepatosomatic index (HSI = Organ weight/Animal weight)
Blood samples from rats were collected and placed in tubes containing anticoagulant (LABOR IMPORT ®)
Hematological analysis was performed using a Sysmex KX-21N hematological counter
This analysis was divided into erythrogram
which corresponds to counting and morphological analysis of erythrocytes
which corresponds to counting and morphological analysis of leukocytes
Analysis of biochemical parameters was performed on plasma
Total cholesterol and albumin levels were determined by colorimetric enzymatic assays
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were determined by a kinetic test performed with the COBAS MIRA PLUS® (Roche)
employing the Gold Analisa Kits Diagnóstica®
Representative liver fragments were fixed in formaldehyde for 24 h
and embedded in paraffin with Histosec plastic polymer (Merck)
Slices 2 to 5 μm in thickness were obtained and stained with Hematoxylin & Eosin
with additional slices stained by the histochemical PAS-H method
and material documentation were performed on an Olympus BX41 photomicroscope
Two slides per treatment were selected for morphometry analysis
in which a total of seven sections were photographed
The diameter of hepatocytes and their nuclei were subsequently measured using the Image Pro Plus Media Cybernetics software (version 4.5) for calculation of the hepatocyte: hepatocyte nucleus ratio
The results were submitted to the normality test and to the homogeneity test of the variances
For variables whose distribution was normal
the analysis of variance was applied and when significant
the means were compared by the Tukey test at 5% probability
Toxicity analysis of the diets containing 5
or 25% of the cottonseed cake or biodetoxified substrates followed a completely randomized design
Statistical analyses were performed using RStudio software (version 1.1.423
Figure 1 Macrofungal cultivation on substrates of cottonseed cake and agricultural biomass: (A) Solid-state cultivation with Fistulina hepatica (BCC-FH); (B) solid-state cultivation of Pleurotus ostreatus (BCC-PO) and fructification
The treatment T2 (cottonseed cake: sugarcane bagasse) resulted in the greatest total mycelial colonization by F. hepatica (BCC-FH), with T1 (cottonseed cake: eucalyptus sawdust) most appropriate for P. ostreatus (BCC-PO). Biological efficiencies were observed in the region of 70% for T1 and 50% for T2, with percentage productivity not significantly different across the substrates (Figure 2)
a high contamination rate was observed (> 40%)
likely as a result of the slow growth of the two fungi on these substrates permitting colonization by other undesirable microorganisms over time

T1: Eucalyptus sawdust; T2: Sugarcane bagasse; T3: Compressed oil palm fruit fiber; T4: Elephant grass
mean values that are followed by the same lower-case letter do not differ significantly in terms of biological efficiency
mean values followed by the same upper-case letter do not differ significantly regarding productivity across treatments (P<0,05)
For both fungal strains, a significant reduction in FG content was observed following T1 and T2 biological assay treatments (Figure 3)

Formulations and diet compositions for toxic cottonseed cake feed assays and biodetoxified cottonseed cake feed assays are presented in Tables 1, 2
Table 1 Formulation and bromatological composition (%) of the diets containing untreated cottonseed cake
Table 2 Formulation and bromatological composition of the experimental diets containing biodetoxifed cottonseed cake
Table 3 Growth parameters of rats fed with different levels of cottonseed cake
Weight gains followed the same pattern of feed intake, consequently reflecting differences in feed conversion (Table 3)
the main organ to metabolize nutrients ingested in the diet
presented a negative response to the inclusion of cottonseed cake
which was reflected in the hepatosomatic index
Biochemical parameters associated with hepatic functions were also affected, with ALT increasing as cottonseed cake content increased. Conversely, AST levels in rats fed on cottonseed cake were lower than those fed on control diets (Table 4)
A significant decrease in serum albumin levels was observed in the group fed on cottonseed cake
Cholesterol levels were not altered by any diets during the toxicity test
hemograms were also unaltered by the diets (data not shown)

In this study, the toxic effects of gossypol in rats were clearly demonstrated in toxicity assays, with poor development rates observed. Reduction in weight as a process of intoxication by gossypol was likely a consequence of liver damage, as reported previously (De Carvalho et al., 2013)
It is noteworthy the evidence of hepatitis and hepatocyte degeneration as a consequence of metabolic damage caused by gossypol-containing diets (De Carvalho et al., 2013). The histopathological changes observed here in the cottonseed cake toxicity assay indicate likely impaired liver structures and functioning (Ahmed, 2018)
Such effects are corroborated in the present study
where cholesterol reduction in rats was apparent after feeding with biodetoxified cottonseed cake produced with both P
Hepatoprotective action with albumin maintenance and benefits toward a decrease in ALT and AST enzyme activities have been demonstrated with the use of functional foods (Ahmed, 2018). The hepatoprotective action of bioactive substances has also been demonstrated in liver histopathological studies (Ahmed, 2018)
Our study suggests that the use of cottonseed cake bio-detoxified through the cultivation of P
ostreatus resulted in the maintenance of liver tissues and cordonal arrangement
with cells displaying normal nuclei and cytoplasm without vacuoles or fat deposits
Such histopathological data supports the likely bioactive effect of the treatments with the macrofungi and the potential for downstream employment of the macrofungi treated cottonseed cake in feed applications
Biodetoxification of cottonseed cake through solid-state cultivation with the macrofungi P
hepatica minimized the toxic effects of free gossypol in feed-formulation for rats
ostreatus-derived biodetoxified cottonseed cake in feed-formulation diets did not result in toxic effects regarding the health and growth of Wistar rats
Further studies are warranted into the potential for reduction of fiber content of biodetoxified cottonseed cake using macrofungi
as well as mass spectrometry-based investigations into beneficial secondary metabolite accumulation in fermented products that may add further gains for monogastric animal feed

Porto are in the driver’s seat in the Taça de Portugal semi-finals after beating Vitória de Guimarães 1-0 in the first leg at Estádio Dom Afonso Henriques
Neither goalkeeper was seriously tested until the 52nd minute when the Dragons went in front
Nico González picked out Pepê with a pinpoint cross
his header straight at Bruno Varela who spilled the ball which rolled into the post and over the line
Vitória had a fantastic chance to draw level in the 86th minute
Kaio César butchering an opportunity to send Jota Silva in on goal
Porto's problems with referees continued in the opening minute of the match when Toni Borevković fouled Evanilson
The centre-back landed a cheap shot on the Brazilian while he was down
Pepê Aquino close to being booked for dissent after disrespecting Nuno Miguel Serrano Almeida
Ricardo Mangas and Jorge Sánchez required treatment after a nasty head clash
the game stopped for eight minutes as the defenders received treatment and strapped on swimming caps
Otávio took out Jota Silva twice in quick succession but Vitória were unable to profit from the free kicks
The Dragons saw a penalty claim denied after Gonçalo Borges got into the box and bundled into Bruno Varela
Chances were proving hard to come by before Nico González and Alan Varela were unable to keep their efforts down
João Mendes dragging his effort wide at the other end
The second half started with Nélson Oliveira’s only attempt comfortably saved by Cláudio Ramos
Porto scored the decisive goal in the 52nd minute
his header straight at Varela who fumbled the ball and watched it hit the base of the post and roll into his net
Mendes was booked for bringing down Pepê and immediately replaced by Kaio César
Sérgio Conceição had another reason to be upset with Almeida after a cynical handball by Borevković prevented Evanilson racing clear
perhaps fortunate to avoid a straight red for being the last man
Romário Baró replaced Gonçalo Borges before Conceição made a triple switch as Joäo Mário
Iván Jaime and Danny Namaso replace González
The substitutions didn’t take long to get involved
Jaime teeing up Baró who saw his fierce strike tipped over the bar by Varela
Guimarães had a fantastic chance to equalise in the 86th minute after Mário slipped over
César experiencing a brain explosion after failing to release an unmarked Jota Siva
Jaime fashioned the final chance in added time
It was a low quality game at Estádio Dom Afonso Henriques
in stark contrast to the excitement provided by Benfica and Sporting Clube de Portugal on the previous evening
The Dragons did just enough to make it 11 straight wins against the Conquerors
taking a big step towards a clash against Sporting CP in the Taça de Portugal final in Jamor
Porto now host Vitória twice in the space of ten days
in the Primeira Liga on Sunday and in the semi-final second leg on Wednesday 17 April
By Matthew Marshall
Saturday night’s clássico is without doubt the biggest game of the Primeira Liga this season
one that will be a huge indicator of who will be crowned champions in May
With just 10 games left in the league after tomorrow’s showdown only a single point separates the top two sides
Porto are currently in pole position to reclaim the Portuguese league title but since changing coach Benfica have started mounting a mighty challenge
Both teams are in fantastic form going into this match. Benfica, who have turned into a free scoring machine under Bruno Lage, have won every single league game since Rui Vitória was dismissed and the former B-team coach promoted. That said, the only defeat for Lage in his short tenure was to Porto, a 3-1 loss in the Taça da Liga semi-final back in January
A win for Benfica would see them leapfrog Porto into first
with most analysts agreeing the Eagles have a theoretically easier fixture list for the remainder of the season
But Benfica have struggled in recent years to win at the Estádio do Dragão
with just one league win in Porto since 2011
Maybe that can change thanks to the goals galore the Lisbon club are scoring; Benfica are the Primeira Liga’s best attack this season
On the other side of the coin, Benfica will be facing the best defence in the league. Much like their title rivals, Porto have been in fantastic form. Sérgio Conceição’s side are undefeated in the league since 7 October, interestingly a 1-0 defeat to Benfica at the Estádio da Luz
Porto racked up a record-breaking winning streak
Vitória Guimarães and Moreirense in 2019 allowed Benfica to get right on their tails just as it looked like the Dragons were going to run away with it
but Porto seem to have hit form again with impressive back-to-back 3-0 victories over Tondela and Braga
Both managers were coy about what teams they would be fielding
although Conceição chose to recite what he thought would be Benfica’s starting XI
One option for Porto could be to start Moussa Marega after the Malian forward was an unused substitute in Porto’s midweek Taça de Portugal win over Braga
The big centre-forward has made a miraculously quick recovery from a thigh muscle tear
which included a whirlwind trip to China to undergo specialist treatment
Benfica will be without centre-back Jardel
despite the Porto manager’s prediction that the Brazilian centre-back could feature
so youngster Ferro should continue his partnership alongside Rúben Dias
Bruno Lage declined the offer to predict Porto’s starting XI but said his team will be prepared whether the league leaders play 4-4-2
like they did in Porto’s league cup victory over Benfica
are likely to stick to their winning formula
It’s a six-point game […] I’m convinced we will be happy in May.” Bruno Lage
What’s decisive is a team being consistent and we have been that in the last two months and we have to continue to be.”
