Casa Luce is an extensive renovation of a mid-century modern home in Arizona‘s Catalina Foothills by HK Associates. Originally designed and built by Tucson architect Tom Gist, the residence featured Gist’s signature earthen walls of burnt adobe supporting a low-slung roof
While the 1960s structure retained its architectural significance
it required substantial updates to align with contemporary living needs
The goal of the redesign was to redefine the home’s essence while respecting its historical character
The home originally included a floor-to-ceiling picture window framing the distant Santa Rita Mountains to the south
the home’s introverted layout centered on a closed-off
The interior was further constrained by a low mechanical bulkhead and a sunken indoor terrarium
both of which disrupted spatial continuity
composed of a grid of painted wood beams filled with textured white plaster
added to the compartmentalized feel of the home

The architects at HK Associates approach the redesign of Casa Luce with the objective of enhancing natural light
The transformation prioritized connecting the home’s interior to its desert surroundings
creating an open transition between indoor and outdoor spaces
The result is a home that is both modern and deeply respectful of its original design
One of the most significant changes in Casa Luce was the removal of four masonry piers that originally supported the central roof
This intervention allowed for a floating ceiling that dramatically alters the perception of space within the main living areas
Achieving this required innovative engineering
The removal of structural obstructions created an open-plan layout that enhances the home’s spatial fluidity

The reimagined Casa Luce incorporates a carefully curated material palette that emphasizes natural light and subtle design details
Artisanal lime plaster walls and sustainable wood veneer cabinetry contribute to a minimal yet sophisticated aesthetic
These materials dialogue with the home’s original elements of concrete
reflecting the balance between structure and environment that defines life in the Sonoran Desert
HK Associates also redefined the bedroom wing of Casa Luce
enclosed corridor into a passage guided by light
A frosted glass screen at the threshold to the kitchen introduces a soft
while the partially exposed roof structure casts bold shadows that change with the movement of the sun
These elements contribute to a dynamic interaction between light and space throughout the home
the original home features burnt adobe walls and a low-slung roof
The outdoor spaces are redesigned to extend the perception of the interior outward
enhancing the home’s connection to its natural surroundings
The panoramic view from the south-facing picture window is now amplified by the addition of an infinity-edge swimming pool
which visually extends toward the distant mountains
a set of long concrete steps appears to emerge from the interior
functioning as amphitheater seating that invites outdoor living while framing the surrounding desert landscape
the redesign focuses on introducing natural light and reorienting the home towards its desert surroundings
a key transformation was the removal of four masonry piers to create a floating ceiling effect

New recommendations from DEFRA’s Hazardous Substances Advisory Committee (HSAC) have set out steps that could make the UK a world leader in more ethical
through early adoption of a risk-based approach to regulation (also called next generation risk assessment)
NAMs are modern methods of chemical testing that utilise advanced technologies to enhance the assessment and regulation of hazardous chemicals by improving the relevance
speed and reliability of toxicological testing
and to support a transition away from animal testing
The report finds that the UK’s technological and scientific capabilities in public health and safety are substantially advanced enough to make the country a global leader in using NAMs for chemical safety assessments
Professor of Environmental Nanosciences at the University of Birmingham (UoB) and Chair of the HSAC said: “The current approach to chemicals regulation
has failed to keep pace with the number of chemicals on the market
and has not kept pace with the advances in science that are providing new insights into the toxicology of substances and their mixtures for assessing health risks to humans and the environment
The time is right for the UK to begin the transition to NAMs-based regulation.”
NAMs and AI-enabled predictive models are rapidly enhancing our ability to understand and predict the effects of chemicals on humans and wildlife
These new approaches are increasingly contributing to safety decision-making across different sectors while reducing the need for animal testing where alternative methods are viable
achieving large-scale impact will require coordinated strategies for accelerating their adoption in regulatory settings
Key Recommendations for UK Chemicals Regulation include:
Professor of Environmental Genomics at the University of Birmingham and Director of the Centre for Environmental Research and Justice (CERJ) is optimistic that the technological roadblocks towards this transition are finally lifted after more than a decade of substantial public and private scientific investments
“The UK is in a position to harvest from the investments of almost a billion pounds from national and European funded research by revisiting what types of evidence are needed to provide greater protection from toxic chemicals
which can now be part of current legal reforms in the UK
As well as the suggestion that the UK could be a world leader in NAMs if these recommendations are followed
the report also argues that the strategic implementation of NAMs can significantly reduce
and potentially replace the use of mammalian animals for chemical safety testing
while improving hazard assessment robustness and efficiency
The report concludes that a progressive regulatory framework is the essential first step in moving toward the integration of NAMs
which can reduce testing costs all while improving the safety and sustainability of the chemicals industry
Dr Margiotta-Casaluci is from The Institute of Pharmaceutical Science (IPS)
The Institute collaborates closely with industry partners
and policymakers to translate its world-leading research into real-world impact
the Genetic & Environmental Toxicology Section carries out pioneering research in mechanistic and predictive toxicology
dedicated to understanding the mechanisms and pathways through which chemicals
and environmental contaminants cause adverse health effects in humans
The Section’s ultimate goals are to leverage this cutting-edge research to enhance the protection of human and environmental health
and to develop state-of-the art educational programmes that will train the next generations of toxicologists
High-value saturation rate running at about 95% compared to an overall rate of 90% across Italian tire maker's facilities
SpA has dedicated around one fifth of its total capex to increasing its capacity to produce high-value
That's according to group CEO Andrea Casaluci
who believes the current level of investment is sufficient to meet growing demand for those products
the utilisation rate across Pirelli factories stands at about 90%
with a saturation rate of about 95% for high-value tires
The high-value rate is always above the average "because we use around 10 million of the high-value capacity to produce standard tires,” the chief executive explained
allows Pirelli sufficient scope to “catch any further opportunity” from the market on the high-value side
the company does not need to accelerate investment in this regard
around 20% of our total capex is dedicated to capacity growth in high-value [tire production]
and this is enough to balance the expected growth in demand.”
Pirelli forecast capex to reach €400 million or 6.0% of sales in 2024
down from €410 million or 6.1% of sales in 2023.
Pirelli reported a “further strengthening in high value” with ≥18” car tire volume growth of 6.8% (market +6.5%)
Pirelli’s gain comprised: Replacement volumes +11.4% (versus +10.1% for the market overall); and OE volumes +0.9% (compared with +1.5% for the market overall).

Multi-center data from establishments in the South of Italy provide a general confidence in using TRT as a consolidative strategy after chemoimmunotherapy. Considering the limits of a restrospective analysis, these preliminary results support the feasibility of the approach and encourage a prospective evaluation.
Volume 14 - 2023 | https://doi.org/10.3389/fimmu.2023.1289434
This article is part of the Research TopicImmunotherapy in Small Cell Lung CancerView all 5 articles
Background: Consolidative thoracic radiotherapy (TRT) has been commonly used in the management of extensive-stage small cell lung cancer (ES-SCLC)
phase III trials exploring first-line chemoimmunotherapy have excluded this treatment approach
there is a strong biological rationale to support the use of radiotherapy (RT) as a boost to sustain anti-tumor immune responses
the benefit of TRT after chemoimmunotherapy remains unclear
The present report describes the real-world experiences of 120 patients with ES-SCLC treated with different chemoimmunotherapy combinations
Preclinical data supporting the hypothesis of anti-tumor immune responses induced by RT are also presented
Methods: A total of 120 ES-SCLC patients treated with chemoimmunotherapy since 2019 in the South of Italy were retrospectively analyzed
None of the patients included in the analysis experienced disease progression after undergoing first-line chemoimmunotherapy
59 patients underwent TRT after a multidisciplinary decision by the treatment team
while efficacy measured in terms of overall survival (OS) and progression-free survival (PFS) was used as the secondary endpoint
Immune pathway activation induced by RT in SCLC cells was explored to investigate the biological rationale for combining RT and immunotherapy
Results: Preclinical data supported the activation of innate immune pathways
including the STimulator of INterferon pathway (STING)
gamma-interferon-inducible protein (IFI-16)
and mitochondrial antiviral-signaling protein (MAVS) related to DNA and RNA release
Clinical data showed that TRT was associated with a good safety profile
while no ≥ G3 radiation-induced adverse events occurred
The median time for TRT onset after cycles of chemoimmunotherapy was 62 days
Total radiation dose and fraction dose of TRT include from 30 Gy in 10 fractions
up to definitive dose in selected patients
Consolidative TRT was associated with a significantly longer PFS than systemic therapy alone (one-year PFS of 61% vs
with a trend toward improved OS (one-year OS of 80% vs
Conclusion: Multi-center data from establishments in the South of Italy provide a general confidence in using TRT as a consolidative strategy after chemoimmunotherapy
Considering the limits of a restrospective analysis
these preliminary results support the feasibility of the approach and encourage a prospective evaluation
Small cell lung cancer (SCLC) is a unique subtype of lung cancer with an aggressive behavior and dismal prognosis. Approximately two-thirds of patients have extensive stage (ES)-SCLC at the diagnosis, with a five-year survival rate of <3.0% (1)
While prospective data are being collected
preclinical and retrospective studies represent a useful tool to guide clinical practice
Using a preclinical SCLC model with H82 and H524 cells and variable basal levels of STING
the present study demonstrated the activation of innate immune pathways after chemo- and radiotherapy
A multi-center retrospective study was performed to characterize the outcomes and toxicities of TRT in real-world ES-SCLC patients treated with first-line chemoimmunotherapy
Data for patients with treatment-naive ES-SCLC were retrospectively collected at 16 Southern Italy cancer centers between June 2020 and April 2023
All patients were treated with four cycles of chemoimmunotherapy followed by immunotherapy maintenance with or without thoracic radiation
Patients with disease progression after four cycles of chemoimmunotherapy or those with disease progression prior to completion of two maintenance immunotherapy cycles were excluded
A total of 120 patients with ES-SCLC treated with chemoimmunotherapy were selected
Indication for TRT as a consolidative treatment after chemoimmunotherapy and the time interval between the fourth chemoimmunotherapy cycle and mediastinal RT onset were assessed. The following patient characteristics were analyzed: age, gender, and presence of hepatic, cerebral, bone, and other metastases at the diagnosis (Table 1)
Table 1 Baseline patient characteristics
The present study was approved by the local Ethics Committee of Istituto Tumori Giovanni Paolo II in Bari (prot
1223 CE) and conducted in accordance with the international standards of good clinical practice
Propensity score matching (PSM) and survival analyses and tests for equality of proportions were performed using the R v.3.6.3 environment
Propensity score matching was carried out using the “MatchIt” R package
Kaplan–Meier curves and Cox hazard regression analyses were implemented via the “survival” package
The Mantel–Cox test used to compare the Kaplan–Meier curves was done using the “survminer” package
while the “ggplot2” package was utilized to depict survival curves
Based on the published data defining a subgroup of SCLC patients, where responders to immunotherapy were classified as “inflamed” (9, 10) patients that express high levels of innate immune pathway genes, such as the STING pathway, and other preclinical data supporting STING levels as potential biomarkers of a response to combination chemo- and immunotherapy (11, 12)
it was hypothesized that activation of the innate immune pathways may represent a tool that can be used to investigate anti-tumor immune activity in vitro
thus confirming that chemotherapy and RT sustain a direct activation of this innate pathway
Figure 1 (A) H524 and (B) H82 SCLC cell lines were treated with or without cisplatin (0.5 µM) for 72 h, irradiated at 4 Gy (or not irradiated), and incubated for 24h Cell lysates were immunoblotted with the indicated antibodies (see Supplementary Material) to detect STING-mediated innate immune activation and DNA damage repair pathways
GAPDH and tubulin were used to ensure equal loading
Figure 2 Both (A) H524 and (B) H82 SCLC cells were treated with cisplatin (CT; 0.5 µM) for 72 h and then irradiated at 4 Gy (RT). After irradiation, both cell groups (1 × 104 cells/well) were cultured for 24 h and mRNA expression levels of innate immune activation markers in both SCLC cell lines were determined by quantitative real-time PCR (see Supplementary Material)
Normalized expression data are represented as mean ± s.e.m
derived from three technical replicates calculated using the comparative method of 2-^(ΔΔCt) (reference gene 18S)
One-tailed unpaired Student’s t-test with 95% confidence interval (CI)
Propensity score matching was used to estimate the RT effect on survival
One-to-one nearest neighbor matching was used
All patients who underwent RT (n=59) were matched to those who did not
reaching a good balance with all standardized mean differences below 0.1 after matching excluded only two RT-untreated subjects
Matched data were then used for survival analyses
Figure 3 (A) Kaplan–Meier curves showing progression-free survival
(B) Kaplan–Meier curves showing overall survival
Figure 4 (A) Kaplan–Mier curves showing progression free survival based on radiation BED
(B) Kaplan–Mier curves showing overall survival based on radiation BED
the present study used preclinical SCLC cell models to show a significant positive modulation of innate immune pathway genes (STING and MAVS) accompanied by increased DNA damage with sequential chemotherapy and RT treatment in vitro
These data suggest that this strategy may amplify the immune response in patients
the preclinical in vitro data may not allow for consideration of the impact of the immune microenvironment
thus providing only a partial estimate of the interactions between RT and immune response
recently closed the recruitment due to high number of grade 5 AEs
even if these AEs are not clearly tied to either immunotherapy or TRT
A good safety profile for TRT in SCLC patients treated with chemoimmunotherapy was also noted
A significant positive modulation of the innate immune pathway genes (STING and MAVS) was demonstrated in SCLC cell models using sequential chemotherapy and RT treatments in vitro
suggesting a possible role of TRT in ES-SCLC patients treated with chemoimmunotherapy
Multi-center data from Southern Italy provide a general confidence in using TRT as a consolidative strategy after chemoimmunotherapy based on a clinical multidisciplinary decision

A Corrigendum to this article was published on 20 June 2016
This article has been updated
The Adverse Outcome Pathway (AOP) framework represents a valuable conceptual tool to systematically integrate existing toxicological knowledge from a mechanistic perspective to facilitate predictions of chemical-induced effects across species
its application for decision-making requires the transition from qualitative to quantitative AOP (qAOP)
Here we used a fish model and the synthetic glucocorticoid beclomethasone dipropionate (BDP) to investigate the role of chemical-specific properties
and internal exposure dynamics in the development of qAOPs
We generated a qAOP network based on drug plasma concentrations and focused on immunodepression
disruption of gluconeogenesis and reproductive performance
We showed that internal exposure dynamics and chemical-specific properties influence the development of qAOPs and their predictive power
Comparing the effects of two different glucocorticoids
we highlight how relatively similar in vitro hazard-based indicators can lead to different in vivo risk
This discrepancy can be predicted by their different uptake potential
pharmacokinetic (PK) and pharmacodynamic (PD) profiles
We recommend that the development phase of qAOPs should include the application of species-specific uptake and physiologically-based PK/PD models
This integration will significantly enhance the predictive power
enabling a more accurate assessment of the risk and the reliable transferability of qAOPs across chemicals
will allow the full exploitation of the AOP predictive potential
IVIVE is highly relevant to drive risk assessment since
the risk of effects at levels of organization higher than those considered in the in vitro assay has very narrow limits of tolerance
in other cases a certain level of risk is accepted and the attention is focused instead on risk management
the modulation of a molecular target (or pathway) does not automatically imply that the potential consequent effects will be adverse or adverse enough to be not tolerable
Examples of risk management and tolerated chemical-induced effects are
determination of drug safety margins in humans and effects in wildlife that do not affect population dynamics
AOPs are relevant for risk management since they are intended to cover all levels of biological organization
risk can be assessed on the basis of the most relevant part of the pathway (e.g
molecular level vs population level) for different target-species (e.g
humans vs wildlife) and the most relevant exposure route
Synthetic glucocorticoids are able to modulate the GR and are widely prescribed to treat
together with the ability of some synthetic glucocorticoids to interact also with other steroid receptors (i.e
Our study aimed at disentangling the complexity of in vivo responses to chronic exposure to synthetic glucocorticoids and to synthesise this information into a predictive qAOP network
We focused on three major pathways leading to perturbation of blood glucose homeostasis
We demonstrated how internal exposure dynamics and chemical-specific PK/PD properties have profound implications for the occurrence of multi-scale effects
We propose that the explicit consideration of PK and PD during the development phase will enhance the predictive power of qAOPs and their transferability across chemicals and across species
Mean measured water concentrations in the 10 and 1000 ng/L groups were
Log D7.4 and measured water concentrations of BDP on sampling day as inputs
(c,d) Predicted plasma concentrations for fish exposed to 1000 ng BDP/L (nominal concentration) in Experiment 1 and Experiment 2
Fish in the two experiments were exposed to the same peak concentrations of BDP (Cmax) but to different total drug concentration over time (AUCs)
The predicted internal exposure profile was used to calculate time-integrated plasma concentrations expressed as AUC values
Average drug plasma concentration in fish exposed to 10 ng BDP/L in Experiment 2 was within the Human Therapeutic Plasma Concentrations (HTPC) range expressed as Cmax (0.8–1.4 ng/mL)
whereas plasma concentrations fish exposed to 1000 ng BDP/L were approximately 50-fold higher than the HTPC range
suggesting the likelihood of significant toxicological effects
it is predicted that drug plasma concentration in fish exposed to 10 ng BDP/L in Experiment 1 reached the HTPC range once every 4 days
whereas in the same 4-day period it oscillated between 1- and 10-fold HTPC in the group exposed to 100 ng BDP/L and between 10-and 100-fold HTPC in the group exposed to 1000 ng BDP/L
(a) Relationship between PEPCK gene expression and increase of blood glucose in fish exposed to increasing plasma concentrations of BDP
Best-fit regression curves are shown for PEPCK gene expression measured in the liver (solid black curve) and blood glucose concentration (solid red curve)
Effect magnitude was calculated for each individual sample as fold-changes versus the control mean value
(b) Highly significant correlations were observed between PEPCK and GR gene expression and (c) between PEPCK gene expression and blood glucose concentrations
The solid red line represents the linear regression curve
the dashed lines the 95% confidence interval
White blood cells were analysed by flow-cytometry and changes in the percentages of lymphocytes
precursors and granulocytes were quantified in each individual fish
(a) Percentage of lymphocytes in fish exposed to oscillating (oscill.) or sustained (sust.) concentrations of BDP for 21 days (n = 30–36)
(b) Percentage of precursor cells and (c) granulocytes in fish exposed to sustained concentrations of BDP (1 and 60 ng·h/mL) for 21 days (n = 30–36)
(d–f) Representative forward scatter (FSC) versus side scatter (SSC) profile of white blood cells in control fish and in fish exposed to sustained concentrations (1 and 60 ng·h/mL) of BDP for 21 days
Note the concentration-dependent changes in the components of white blood cells populations
Best-fit regression curves for GR gene expression (solid black curve) and decrease of lymphocyte (lymphocytopenia
solid red curve) expressed as effect magnitude at increasing plasma concentrations of BDP (expressed as AUC)
Note the changes in the two curves in conditions of oscillating versus sustained exposure dynamics
(a) Relative Mean Normalized Expression (MNE) levels of AR measured in the liver of fish exposed to increasing plasma concentrations of BDP over 21 days (n = 12–20) and (b) fatpad height (n = 36) in the same fish
Fatpad is an androgen-dependent secondary sexual characteristic typical of fathead minnow males
and asterisks a significant difference versus the control group (p < 0.05)
(c,d) These data were used to generate the best-fit regression curves for AR gene expression (solid black curve) and the fatpad height (solid red curve) expressed as effect magnitude at increasing plasma concentrations of BDP (expressed as AUC) in conditions of oscillating and sustained exposure to BDP
Full lines indicate known cause-effect linkages
whereas dashed lines indicate hypothesised linkages or linkages for which the direction of the response is difficult to predict or generalise (i.e
The asterisk indicates that the EC50 value for the modulation of AR refers to BOH
Note that the immune response is highly dynamic and dependent on the dynamic of exposure
using synthetic glucocorticoids as model chemicals
internal exposure and chemical-specific PK/PD properties have profound influences not only on the application of a given AOP
but also on AOP development and its potential transferability across chemicals in a decision-making context
determining the pathway-specific sensitivity to this factor can increase the predictive power of the qAOP
Anchoring these responses to adverse phenotypes arising after chronic exposure is still a critical factor for data interpretation
whereas plasma concentrations of BDP in fish that exhibited adverse effects were 1 to 50-fold higher than the blood concentrations measured in humans after BDP administration via inhalation.The example of BDP and DEX clearly indicate that chemical-specific properties should be carefully considered in the studies performed with the aim to develop qAOPs and in the selection of reference chemicals
similarly potent compounds with different uptake and PK profiles may exhibit different in vivo risks
This discrepancy can be predicted by uptake and PK/PD considerations
but its success is critically dependent on the accurate extrapolation of dosimetry
The development of more accurate physiologically-based PK/PD models able to tackle chronic exposure scenarios for different model species will empower cross-species extrapolation and allow us to maximise the informative and predictive power of data generated using different models
All the experimental in vivo protocols and procedures involving fish were performed in accordance with the United Kingdom Animals (Scientific Procedures) Act
The in vivo studies were carried out at Brunel University London (United Kingdom) under Project License and Personal Licences granted and approved by the United Kingdom Home Office
All in vivo experimental protocols were also approved by the Research Ethics Committee of Brunel University London
Experiment 1 included three treatment groups exposed to nominal concentrations of 10
100 and 1000 ng BDP/L and one control group receiving only clean water
Each treatment group included three replicate tanks
each hosting 12 adult male fathead minnows (36 fish per treatment)
Experiment 2 included two treatment groups exposed to 10 and 1000 ng BDP/L and one solvent control group
Water in all fish tanks contained DMF at 0.0095%
which is within the limit recommended by OECD guidelines
The observed range of therapeutic Cmax of 17-BMP was between 0.8 and 1.4 ng/mL
It is important to note that these concentrations reflect the systemic level of 17-BMP after inhalation
It is likely that concentrations of 17-BMP in the upper respiratory tract are higher than the systemic concentrations in the blood
blood concentrations are highly relevant for the prediction of adverse effects at systemic level
the first exposure concentration (10 ng/L) was selected as it was the NOEC of Experiment 1
The aim was to evaluate if the NOEC was constant under different exposure dynamics
The second concentration (1000 ng/L) induced statistically observable effects in the majority of measured endpoints
The aim was to evaluate if different exposure dynamics are able to affect the magnitude of the effects
the question was whether the response of each endpoint was driven by the Cmax or by the AUC
which takes into account the amplification efficiency of both the target genes and the reference gene to calculate the mean normalized expression (MNE) of each target gene
The Log KOW and the Log D7.4 used in the model were predicted by ALOGPS and were
The predictions of the FPM were based on water concentrations measured on Day 21
Water concentrations measured at different time points during the studies were used to predict drug plasma concentrations over 21 days
The latter was calculated using the GraphPad Prism Software (GraphPad Software
Statistical significance was set at a level of p < 0.05
No data were available for the in vitro modulation of AR by 17-BMP
thus the EC50 for BOH was used (EC50 = 12 nM = 5 ng/mL; AR beta-lactamase assay in agonist mode; Pubchem ID 20469)

Standard-tires focus and low plant utilisation rates in country now accounting for less than 3% of group sales
Italy – Pirelli’s tire plants in Russia are running at a capacity-utilisation rate of around 65% with output fully dedicated to the local market
the Russian operations are focused on the production of standard tires
explained on a recent first quarter results call
Pirelli’s performance in the standard tires segment
“reflects greater selectivity in this channel and the halting of car production [by major OEs] in Russia due to the Ukraine conflict.”
the ‘saturation’ level of Pirelli plants was around 90% – over 95% in the high-value tire production – further underlining the lower utilisation rates in Russia
While Russia still represents 8% of Pirelli’s production
the country now “accounts for less than 3% of our total sales
So it is [becoming] less & less meaningful,” said Casaluci
Pirelli exported around 3.5 million tires from Russia
adding: “Today the export is finished
those exports are delivered from local production in Romania and partially from Turkey through an off-take agreement
Pirelli’s first-quarter report also noted a ‘normalisation’ of energy and raw materials costs from the market disruptions that followed the onset of Russia’s war on Ukraine
These adjustments included declines of 16% and 47% respectively for Brent crude and European natural gas prices compared to the first three months of last year
natural rubber (TSR20) traded 23% lower year-on-year
while butadiene at €970/tonne averaged 9% lower than in the first quarter of 2022
Pirelli’s plants at Kirov and Voronezh have annual capacities to produce 6 million units and 2.3 million units respectively of passenger car and light truck tires
