Summary: Plants need to adapt to changing temperature conditions in their environment to survive and thrive. Various protein kinases are involved in plant responses to cold acclimation and heat stress, but their roles in mild temperature changes remain poorly understood. Understanding plant temperature responses is crucial for developing thermotolerant crops.

Summary: In this study, researchers found that combining HA with permissive DEH does not enhance improvements in VO2max or time-trial performance in a temperate environment compared to EUH, and does not increase markers of AKI.

Summary: Exposure to moderately high temperatures allows plants to acquire thermotolerance by removing H3K27me3 and maintaining H3K4me3 levels, enabling them to 'remember' the heat experience. JMJs mediate the balance between H3K27me3 and H3K4me3 at the HSP21 locus during heat acclimation.

Summary: In this study, potential genes related to the heat resistance of L. plantarum CGMCC8198 were identified through transcriptomics and bioinformatics analysis. Expressing these genes in Escherichia coli improved the survival rate, hydrophobicity, and membrane integrity of the recombinant bacteria under high temperature. A strain with better heat tolerance was obtained through multiple rounds of acclimation, and the upregulation of these four genes, especially hisE, was observed in the acclimated strain when treated with high temperature. These findings suggest that adhE-like and other potential genes can enhance the heat resistance of lactic acid bacteria and may serve as indicators for screening heat-tolerant probiotic strains.

Summary: Climate change has resulted in more intense and prolonged heat waves and drought stresses, exceeding the adaptative capacity of trees. This research focuses on the metabolic responses of maritime pine to different intensities of combined stresses, revealing the importance of considering multiple stresses and intensities for understanding plant responses.

Summary: Global warming has negative impacts on crop production and food security. Different cell components can sense temperature increases, and the responses of plants vary depending on whether the temperatures are mild or excessively hot. This review summarizes recent studies on the genetic networks involved in heat responses in Arabidopsis and crop plants, and highlights strategies to improve grain yield under heat stress from a source-sink perspective. The study also discusses the remaining issues regarding thermosensors and the urgent need to explore acclimation under multifactorial stress combinations.

Summary: Heatwaves are periods of unusually hot weather that persist for several days and nights. They are becoming more frequent and intense worldwide due to ongoing global climate change. Heatwaves increase the risk of heat-related illnesses and can be particularly dangerous for vulnerable populations such as the elderly and children.

Summary: Heat exposure affects the levels of monoaminergic neurotransmitters in the brain, leading to changes in emotional behavior. Short-term heat exposure may increase anxiety, while long-term exposure could decrease anxiety through heat acclimation. These changes are possibly attributed to adjustments in core body temperature and brain monoamine levels.

Summary: In fluctuating climatic environments, heat acclimation in predatory mites is a superior adaptation strategy for effective agricultural pest management. The sustained accumulation of HSP70 proteins results in predatory mites with thermotolerance advantage, promoting their biological control function to pests. The divergent constitutive regulation of HSP70 to a thermal environment allows predators to adapt flexibly to extreme stress.

Summary: The Russian wheat aphid Diuraphis noxia is more cold-tolerant, while the melon aphid Aphis gossypii is a more heat-tolerant insect. Both species showed similar patterns of sugars and polyols under cold and heat acclimation, but differed in their levels of heat shock protein 70.

Summary: The study found that high temperature significantly reduced the photosynthetic assimilation rate due to non-stomatal (biochemical) limitation of photosynthetic processes; chlorophyll fluorescence only showed a mild decrease in the quantum efficiency of photosystem II, indicating mainly reversible heat stress effects; heat stress led to a decrease in the number of active PS II reaction centers (RC/ABS) and overall activity of PSII (PIabs) in all genotypes, while PS I (parameter psi(REo)) was negatively influenced by heat stress only in the non-acclimated variant.

Summary: The study found that hot water immersion (HWI) as a heat acclimation strategy induced greater thermal strain compared to exercise-heat acclimation (EHA) at equivalent temperatures. However, this greater thermal strain did not result in significant differences in cardiovascular, thermoregulatory, or perceptual variables between the two interventions. This suggests that three sessions of HWI may be a potential means to lower heart rate, core temperature, and perceptual strain during exercise in the heat.

Summary: This study assessed the effects of hot water immersion (HWI) before or after a repeated-sprint training in hypoxia (RSH) session conducted in the heat. Results showed that HWI before the exercise session decreased power output and increased core temperature, while HWI after the exercise session had positive effects on reducing physiological strain and improving cycling performance.

Summary: In this randomized, crossover, placebo-controlled trial, it was found that tolerance to simulated hemorrhage was lower after low-dose morphine administration. Such reductions in hemorrhagic tolerance were observed without differences in MSNA burst frequency responses between morphine and placebo trials. These data, the first to be obtained in conscious humans, demonstrate that low-dose morphine reduces hemorrhagic tolerance. Thus, morphine is not an ideal analgesic for a hemorrhaging individual in the prehospital setting.

Summary: Hemorrhage is a major cause of trauma deaths and it is unclear whether analgesics such as fentanyl and morphine reduce hemorrhagic tolerance in humans. Experimental data showed that fentanyl and morphine reduced tolerance to simulated hemorrhage, while ketamine did not. Therefore, morphine should not be used for hemorrhaging individuals in the prehospital setting.
