We previously found stress-reduction in rats exposed to an oxytocin-injected cage-mate. Olfactory impairment and oxytocin antagonist treatment blocked the effect. Here, we investigated effects of social stress on the exposure-induced response and exposure on amygdaloid oxytocin concentrations. CT concentrations in exposed olfactorily impaired, CT antagonist-treated and saline-injected unexposed...

conclusions the present study showed that heat stress had a negative effect on job satisfaction; also there were no significant effects on job stress and job performance. results the results showed that job satisfaction had a negative correlation with wbgt index (r = -0.42, p < 0.001) and hssi (r = -0.49, p < 0.001). also, there was no statistical correlation among occupational stress and job p...

conclusions ptsd from childbirth occurs in some women. early identification of risk factors should lead to early therapeutic intervention in the mothers at risk of ptsd. results one hundred and three (17. 2%) women had symptoms of ptsd following childbirth based on the ptsd symptom scale (pss). the results of logistic regression analysis revealed a significant correlation between maternal occup...

Heat waves that trigger severe droughts are predicted to increase globally; however, we lack an understanding of how trees respond to the combined change of extreme temperatures and water availability. Here, we studied the impacts of two consecutive heat waves as well as post-stress recovery in young Pseudotsuga menziesii (Mirb.) Franco (Douglas-fir) and Robinia pseudoacacia L. (black locust) g...

The gene expression kinetics for human cells exposed to hyperthermic stress are not well characterized. In this study, we identified and characterized the genes that are differentially expressed in human epidermal keratinocyte (HEK) cells exposed to hyperthermic stress. In order to obtain temporal gene expression kinetics, we exposed HEK cells to a heat stress protocol (44 °C for 40 min) and us...

BACKGROUND Heat shock protein 72 (Hsp72) is responsible for maintaining critical cellular function during heat stress. Hsp72 confers thermotolerance and may play a role in heat acclimation. Animal research suggests a difference between sexes in Hsp72 expression in response to exercise, however, human data is lacking. OBJECTIVES To determine sex differences in intracellular heat shock protein ...

Heat stress and ultraviolet light in the UVB range ("sunburn spectrum," 290-320 nm) were found to alter the synthesis of specific proteins in cultured keratinocytes derived from mouse skin. Using giant two-dimensional gels, approximately 2,000 cellular polypeptides labeled with [35S]methionine at 4-5 h after exposure to heat or to UVB were analyzed. Cells conditioned at sublethal temperatures (...

BACKGROUND An adenovirus that expresses both interleukin (IL)-12 and granulocyte-macrophage colony-stimulating-factor (GM-CSF) has been proven to be very effective in treating several tumors, but causes serious normal tissue toxicities. METHODS In this study, a novel adenoviral vector was constructed by placing the human GM-CSF gene under the control of the CMV-IE promoter and human IL-12 gen...

Abstract Extreme weather including heat waves and drought episodes are expected to increase in intensity duration due climate change. Wheat, being a major crop is under extreme threat these stresses especially at the reproductive stage. This review addresses potential of diverse wheat germplasm (originated from landraces synthetic derivatives) cope with stress flowering Here, important marker‐t...
