A three-dimensional computational model of a breast tumor nodule was developed, which incorporated interstitial fluid flow, nanoparticle transport, and heat transfer. The model accounted for the elastic deformation of the soft tissue caused by the infusion pressure at the needle tip. Comparative analyses were performed using a simplified Darcy model to highlight the significance of poroelasticity in capturing complex fluid-structure interactions within the tumor microenvironment. The results revealed that tissue deformation led to the formation of fluid pockets near the infusion site, reducing interstitial fluid pressure (IFP) and altering nanoparticle concentration profiles. Pharmacokinetic assessments using the area under the curve (AUC) indicated that larger nanoparticles with higher initial concentration, enhanced the drug-tissue contact duration, particularly in the tumor region. However, the clustering of nanoparticles within the fluid pockets hinders their magnetic relaxation, leading to a decrease in the specific absorption rate and a delay in thermal damage. This study emphasizes the importance of considering infusion-induced tissue mechanics in the design and optimization of magnetic nanoparticle hyperthermia treatments.

The behavioral adjustments required to support these needs often conflict, especially for terrestrial species, where performance-enhancing body temperatures typically increase the risk of dehydration. The complex interplay among these factors affects all aspects of amphibians’ biology and is thought to be highly sensitive to changes in climate and environment. Herein, we investigated how dehydration affects aspects of the thermal biology of the ground-dwelling frog <em>Leptodactylus fuscus,</em> a species tightly associated with terrestrial habitats. We investigated the frog's locomotor performance across different combinations of temperatures (10, 15, 20, 25, 30 and 35 °C) and hydration levels (100, 90 and 80 %), focusing on traits such as optimal temperature, maximal performance, and thermal performance breadth. We also investigated how dehydration affected their preferred body temperature, critical thermal maximum and minimum, and the thermal tolerance breadth. We found that dehydration reduced maximal performance capacity but did not affect optimal temperature or thermal performance breadth. Dehydrated frogs reduced their critical thermal maximum but not the critical thermal minimum, and as a result, narrowed their thermal tolerance breadth. Dehydration did not affect the frog's preferred body temperature, a response thought to be convenient to water conservation, since it reduces the potential for evaporative water loss. In general, the interplay between performance, temperature, and hydration state in <em>L. fuscus</em> seems to reflect the more terrestrial habit of this species and the climatic features of its habitat. The deleterious effects of combined hot and dehydrating conditions on the absolute levels of maximal performance may bear important consequences to the fitness and persistence of the species, and predicted scenarios of extreme heat and intense drought events bear more concern in the light of these findings.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"132 ","pages":"Article 104232"},"PeriodicalIF":2.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144864014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrating these models with thermoregulation models can aid in formulating energy-efficient local warming and heating, ventilation, and air conditioning (HVAC) operational strategies for occupant-centric winter conditioning in battery electric vehicles (BEVs)—a critical step toward their widespread adoption. However, the Berkeley local sensation (LS) model requires accurate consideration of setpoint and setpoint adaptation to ensure reliable predictions. Since the dynamic responses and excitatory–inhibitory interactions between the cold- and warm-sensitive thermoreceptors may inherently entail setpoint adaptation, expressing the LS model in terms of the receptor responses offers a promising alternative. This study evaluates a thermoreceptor-response-based LS model by incorporatingnet cold- and warm-sensitive receptor responses into the existing framework. Model coefficients were regressed and tested on two independent datasets from experiments simulating routine cabin environments during outdoor winter conditions. The results showed a reasonable fit for the development dataset A, with root mean-squared error (<em>RMSE</em>) values in the range of 0.29–0.59 and coefficient of determination (<em>R</em><sup><em>2</em></sup>) values of 0.65–0.92.

To investigate these aspects, this study examined the effects of cold stress on intestinal barrier integrity and explored the protective potential of sodium butyrate supplementation. Forty-five-day-old broilers were randomly assigned to either a control group (CON, thermoneutral at 30 ± 1 °C) or a cold stress group (CS, exposed to 10 ± 1 °C) for 48 h. Intestinal tissues were analyzed for histopathology, tight junction protein expression, oxidative stress markers (CAT, MDA, T-SOD, T-AOC), inflammatory cytokines (LITAF, TNF-α, IL-1β, IL-6, IL-8, IL-10), and pyroptosis-related indicators (Caspase-1, NLRP3). Cold stress significantly disrupted intestinal barrier function, as evidenced by histopathological damage and altered expression of tight junction proteins. The CS group exhibited increased oxidative stress, elevated inflammatory cytokines, and enhanced pyroptosis activation. Given sodium butyrate's role as a crucial energy source for intestinal cells and its reported anti-inflammatory properties, we hypothesized it could mitigate cold stress-induced damage. To test this, an in vitro model using chicken macrophage HD11 cells subjected to cold stress was treated with sodium butyrate (1 mM). Sodium butyrate effectively alleviated oxidative stress and suppressed pyroptosis in cold-stressed HD11 cells. Mechanistic analysis revealed that this protection was associated with the inhibition of the NLRP3/Caspase-1 signaling pathway. These findings demonstrate that sodium butyrate supplementation attenuates cold stress-induced intestinal damage in broilers, likely through mitigating oxidative stress and inhibiting NLRP3 inflammasome-mediated pyroptosis, highlighting its potential as a protective dietary intervention.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"132 ","pages":"Article 104239"},"PeriodicalIF":2.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144864007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an in vivo study, milk samples were collected from thirty mid-lactating Holstein cows in different seasons with varying temperature–humidity index (severe–moderate, SM; moderate–mild, MM; and mild–comfortable, MC). The average daily milk yield of cows was 33.93 ± 0.98 kg; cows were fed a TMR diet, delivered twice daily, and ad libitum access to water.
