In the eusocial paper wasps <em>Polistes</em> sp.<em>,</em> colony-forming insects with open nests, the larvae and pupae have limited options to influence their own body temperature in response to high environmental temperatures. They are dependent on measures taken by the adults to keep it at tolerable levels. We determined the upper thermal limits (CT<sub>max</sub>) in field populations of three paper wasp species (<em>Polistes dominula</em>, <em>P. gallicus</em>, <em>P. biglumis</em>) from different climates (temperate, Mediterranean, alpine) for three life stages (larvae, pupae, adults). Due to morphological and physiological characteristics of the individual life stages, they did not show the same reactions to temperature rise and heat stress in terms of respiration and body movement. CT<sub>max</sub> evaluation by established methods (mortal fall, short-term respiration patterns) was not possible, so we had to develop an adapted evaluation type based on long term respiration patterns. The most striking result was that the CT<sub>max</sub> was similar in all populations and life stages, ranging from 47.6 to 48.8 °C in larvae and pupae, and from 47.1 to 47.9 °C in adults. <em>P. dominula</em> differed from <em>P. gallicus</em> and <em>P. biglumis</em>; the latter did not differ significantly (all stages).

This study explores the use of hybrid magnetic nanofluids to optimize treatment effectiveness while minimizing side effects. Preoperative modeling was employed to determine the optimal nanoparticle type, concentration, and combination for enhanced thermal efficiency. Three magnetic nanoparticles—maghemite, magnetite, and FccFePt—were analyzed, both individually and in hybrid compositions. Results demonstrated that increasing nanoparticle concentration significantly reduced treatment duration and minimized healthy tissue necrosis. At 0.1 % concentration, treatment times for maghemite, magnetite, and FccFePt were 3, 67, and 90 s, with corresponding healthy tissue loss-to-tumor volume ratios of 0.06, 3.08, and 4.36. Lowering the concentration to 0.05 % increased treatment times to 46, 126, and 129 s, raising tissue loss ratios to 1.88, 6.65, and 8.36. Notably, hybrid nanoparticle compositions showed divers but non-uniform effects, with some combinations marginally improving treatment efficacy while others had negligible impact. The hybridization of maghemite and FccFePt reduced necrosis time, but its influence on overall treatment efficiency was inconsistent. These findings underscore the potential of hybrid nanoparticles to enhance microwave ablation therapy; however, they also highlight the complexity of nanoparticle interactions, emphasizing the need for precise selection and concentration optimization to achieve superior treatment outcomes while preserving healthy tissue.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"129 ","pages":"Article 104117"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143859251","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}

The objectives of this study were to establish an experimental system to evaluate postprandial thermal feeling based on behavioral thermoregulation, investigate it among different meat species and their fractions, and clarify the relationship between their thermal nature and the active meat constituents that affect thermal feeling. Freeze-dried meat, defatted meat, and extracted fat were prepared from horse meat, chicken, pork, beef, mutton, and venison. After feeding, mice were placed in an elongated chamber equipped with a continuous thermogradient floor. An obvious peak in the cumulative staying time at the mouse's preferred temperature was observed after 30 min, and the postprandial thermal feeling was evaluated by examining the preferred temperatures. As a result, purified meat proteins were not considered to affect postprandial thermal feeling among meat species. In contrast, the ethanol and water extracts of defatted horse meat induced a “cool feeling,” and the extracts of other meat species induced a “warm feeling.” Chicken and pork fat induced a cool feeling, whereas beef and mutton fat induced a warm feeling. Additionally, certain dose-dependent constituent(s) in these fats affected the postprandial thermal feeling. Using the established evaluation system, it was concluded that the extract and fat in meat are involved in the postprandial thermal feeling, and the thermal nature of the meat in TCM depends not only on animal-specific components but also on their contents.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"129 ","pages":"Article 104101"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747040","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}

To persist in streams with unsuitable thermal habitat, fish must move to coldwater patches, acclimate, or adapt to water temperatures above thermal optima. Brook trout, a coldwater adapted salmonid, has previously displayed physiological plasticity and the ability for reversible thermal acclimation when reared at higher temperatures. However, because stream temperatures are not static, it is important to explore the rate at which thermal acclimation occurs to evaluate whether prior thermal experience will influence future thermal performance. To determine the temporal scale in loss of thermal acclimation as water temperatures cool, we acclimated brook trout to three thermal regimes: +0 °C (ambient; mimicking the daily average water temperature of a nearby long-term study site), as well as +2 °C and +4 °C above ambient. After 2 years of being reared under those conditions, fish from the warmer treatments were moved to a common, colder temperature (ambient). We then used critical thermal maximum to measure the loss in acclimation response of fish from each treatment over time. We found that regardless of initial acclimation temperature, thermal tolerance of warm acclimated fish decreased rapidly for 1 week, then gradually decreased, and was completely lost within 42 days. This gradual loss of acclimation may be valuable to persistence in warmer streams and will be important to include in models of the impact climate change has on brook trout and other aquatic ectotherms with significant thermal plasticity.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"129 ","pages":"Article 104103"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776728","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}
