Docetaxel (DTX), a widely used chemotherapeutic agent for PC, requires high doses, often resulting in severe side effects. Combining DTX with hyperthermia has the potential to enhance therapeutic efficacy while reducing the required drug concentration. In this context, magnetic fluid hyperthermia (MFH) is emerging as a promising treatment modality for solid tumors, including PC. In this study, the combinatorial effect of citric acid-coated Mn<sub>0.9</sub>Zn<sub>0.1</sub>Fe<sub>2</sub>O<sub>4</sub> magnetic nanoparticle-mediated MFH and DTX on PC cells LNCaP is analyzed. Cell viability, therapeutic synergy, and mode of cell death are evaluated following the two treatment sequences: (i) DTX at IC<sub>20</sub> for 24 and 48 h followed by MFH (42<strong>-</strong>45 °C for 1 h), and (ii) MFH followed by DTX for the same durations. The results show that therapeutic efficacy strongly depends on treatment sequence. MFH followed by DTX induces the highest cytotoxicity, achieving approximately 80–85% cell death, predominantly through apoptosis, indicating strong synergism. In contrast, the reverse sequence results in approximately 60% cell death while maintaining a synergistic interaction. These findings highlight the importance of treatment sequencing and the potential of MFH-assisted combination therapy to enhance therapeutic outcomes in PC.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"141 ","pages":"Article 104576"},"PeriodicalIF":3.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149111500","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}

Previous insect studies have suggested that heat tolerance may be influenced by species identity, local adaptation, and phenotypic plasticity, with potential constraints among these factors. However, studies that allow the simultaneous partitioning of these effects are rare except in a few model organisms. We address this issue in a guild of four thrips pest. All species followed an injury accumulation model, with <em>Megalurothrips usitatus</em>, <em>Frankliniella intonsa</em>, and <em>Frankliniella occidentalis</em> exhibiting similar coefficients of thermal sensitivity (z = 5.2 to 5.4), while <em>Thrips palmi</em> showed higher sensitivity (z = 6.85), demonstrating a more rapid decline in tolerance with increasing temperature. Common-garden experiments showed significant among-population variation of heat tolerance within each species, with patterns appearing to match local climates. Nevertheless, species identity remained the dominant determinant of heat tolerance when compared to geographical variation. Short non-lethal exposures to heat (hardening) and longer-term exposures (acclimation) produced variable responses depending on species and conditions. Variance partitioning revealed species identity as the dominant determinant of heat tolerance, explaining 22.3% of the total variance, compared with among-population geographic variation (19.4%), Plasticity collectively accounted for 12.05% of the total variance, comprising 4.69% from baseline plasticity and 7.36% from species-specific plastic responses. This multidimensional framework clarifies how genetic differentiation and limited plasticity interact to shape thrips thermal niches and provides a mechanistic basis for predicting seasonal dominance and range shifts of these key pest species under intensifying heat extremes.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"141 ","pages":"Article 104586"},"PeriodicalIF":3.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149167339","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 governing equations are decoupled by the separation of variables method and Duhamel's integral, and the resulting series solutions agree with COMSOL finite-element benchmarks to within 0.12% for the peak temperature and 5% for the peak stress. The results reveal three primary modulation mechanisms. First, an increase in the heat flux phase lag reduces both the surface peak temperature and the maximum compressive stress, whereas an increase in the temperature gradient phase lag promotes deeper energy diffusion and elevates the temperature and thermal expansion strain in sub-surface tissues. Second, the intrinsic tissue properties exert a dual damping effect: a higher tissue density attenuates both the thermal and mechanical responses, whereas increased microcirculatory blood perfusion provides only limited cooling against extreme temperature peaks. Third, the laser characteristics govern the safety boundaries: longer wavelengths substantially reduce the surface temperature and compressive stress, whereas a higher power density nonlinearly escalates the induced mechanical stress and the associated risk of tissue damage. The proposed model provides theoretical support for the preliminary determination of laser thermotherapy safety thresholds and the optimization of personalized treatment protocols, while the reported stress-based thresholds remain theoretical predictions that require experimental and clinical validation.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"141 ","pages":"Article 104575"},"PeriodicalIF":3.2,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149075118","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}

Using the stored-product pest <em>Plodia interpunctella</em>, a sperm-heteromorphic moth, we investigated how acute thermal stress (4 h at 40°C) impacts males’ lifetime reproductive resource allocation and offspring fitness. Heat-exposed adult males and controls (26°C) were paired daily with non-stressed females. We found that transient heat stress did not significantly impact pre-courtship duration, courtship duration, copulation latency, longevity, or lifetime mating frequency, nor did it alter offspring developmental duration. Total offspring production and lifetime eupyrene (fertile) sperm transfer also remained unaffected. However, heat-exposed males exhibited a massive hyper-allocation of non-fertilising sperm, ejaculating 53.4% more apyrene sperm at a 56.8% faster rate, increasing lifetime apyrene production by 41.0%. This hyper-allocation suggests that non-fertilising apyrene sperm act as a critical compensatory mechanism, buffering eupyrene sperm to maintain intact reproductive output following severe thermal stress. Although male reproductive performance proved resilient, we observed a subtle inter-generational cost: a 3.5% reduction in male offspring body weight. Our findings highlight a novel, potential adaptive role for sperm heteromorphism, demonstrating that sperm-heteromorphic insects can leverage plastic, morph-specific ejaculate tailoring to safeguard fertility against acute thermal extremes.</div></div>","PeriodicalId":17428,"journal":{"name":"Journal of thermal biology","volume":"140 ","pages":"Article 104562"},"PeriodicalIF":3.2,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148844240","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}
