The primary determinant of vascular adaptations to lifestyle interventions, such as exercise and heat therapy, is repeated elevations in shear stress. Whether skin or core temperatures also modulate the adaptation acute exposure unknown, likely due difficulty dissociating thermal hemodynamic responses heat. We found that modify passive heating irrespective magnitude increase

heat stress is a significant occupational health and safety for workers in petrochemical industries. heat stress is a combination of heat load individual and environmental factors impose on workers’ bodies, which in turn, have impacts on workers’ performance, safety, and health. the present paper is carried out to determine the heat stress levels in workplace and to compare it with allowed wet ...

Relationships between αB-crystallin expression patterns and pathological changes of myocardial cells after heat stress were examined in vitro and in vivo in this study using the H9C2 cell line and Sprague-Dawley rats, respectively. Histopathological lesions, characterized by acute degeneration, karyopyknosis and loss of a defined nucleus, became more severe in rat hearts over the course of heat...

The cytoprotective effect of heat stress proteins on epithelial cell detachment, an important cause of acute, ischemic renal failure, was examined after ATP depletion by evaluating focal adhesion complex (FAC) integrity. The intracellular distribution of FAC proteins (paxillin, talin, and vinculin) was assessed by immunohistochemistry before, during, and after exposure of renal epithelial cells...

The small ubiquitin-like modifier 2 (SUMO-2) is required for survival when cells are exposed to treatments that induce proteotoxic stress by causing the accumulation of misfolded proteins. Exposure of cells to heat shock or other forms of proteotoxic stress induces the conjugation of SUMO-2 to proteins in the nucleus. We investigated the chromatin landscape of SUMO-2 modifications in response t...

Arctic charr thrive at high densities and can live in freshwater year round, making this species especially suitable for inland, closed containment aquaculture. However, it is a cold-water salmonid, which both limits where the species can be farmed and places wild populations at particular risk to climate change. Previously, we identified genes associated with tolerance and intolerance to acute...

Background: Heat stress in the steel industry is considered as a serious threat to the health and safety of workers. A wide spectrum of complications and diseases from mild disorders such as burning sensation to fatal conditions such as thermal shock may occur due to uncontrolled thermal stress. In this study, heat stress assessment was performed according to the wet-bulb globe temperature (WBG...

All organisms have evolved mechanisms that protect them against environmental stress. The major fungal pathogen of humans, Candida albicans, has evolved robust stress responses that protect it against human immune defences and promote its pathogenicity. However, C. albicans is unlikely to be exposed to heat shock as it is obligatorily associated with warm-blooded animals. Therefore, we examined...

The involvement of heat-inducible genes, including the heat-shock genes, in the acute response to temperature stress is well established. However, their importance in genetic adaptation to long-term temperature stress is less clear. Here we use high-density arrays to examine changes in expression for 35 heat-inducible genes in three independent lines of Escherichia coli that evolved at high tem...

conclusions stress had a moderate level in dental students of study, which requires more attention. due to the most level of stress in students of fifth and sixth years, it is recommended to take specific actions for this sensitive period of dentistry education. background studying dentistry environment is important to assess stress causes, which is harmful for educational system. objectives th...
