The liver plays a central role in metabolism and is important in maintaining homeostasis throughout the body. This study integrated transcriptomic and metabolomic data to understand how the liver responds under chronic heat stress. Chickens from a rapidly growing broiler line were heat stressed for 8 hours per day for one week and liver samples were collected at 28 days post hatch. Transcriptom...

The recent literatures indicate that central nervous system (CNS) is highly vulnerable to systemic hyperthermia induced by whole body heating on conscious animals. In the present study, cerebral electrical activity or EEG (electroencephalogram) following exposure to high environmental heat has been studied in moving rats. Rats were divided into three group (i) acute heat stress-subjected to a s...

background: heat stress is one of the agents in the work environment that can create numerous problems for workers. the objective of this research is to study heat stress control in the foundry platform of a steel plant in tehran. methods: in this experimental study, controlling plans were demonstrated for the work conditions improvement in one of steel plant's foundry platforms. for controllin...

Protein stability under changing conditions is of vital importance for the cell and under the control of a fine-tuned network of molecular chaperones. Aging and age-related neurodegenerative diseases are directly associated with enhanced protein instability. Employing C. elegans expressing GFP-tagged luciferase as a reporter for evaluation of protein stability we show that the chaperoning strat...

Continuous wavelet transform (CWT) method has been applied to capture localized time-frequency information of rat electroencephalogram (EEG) in different vigilance states and analyze alterations in transients during awake, slow wave sleep (SWS), and rapid eye movement (REM) sleep stages due to exposure to high environmental heat. Rats were divided in three group (i) acute heat stress-subjected ...

A reliable method of producing physical stress in the rat was developed using heat irradiation, and the possible interaction between chronic ethanol consumption and stress was investigated in a rat model of alcoholism. Chronic heat stress and chronic ethanol consumption each produced mild hypertension in rats. When combined, the two treatments resulted in hypertension more severe than that prod...

heat stress is one of the main obstacles for crop production in many areas of the world including southwest of iran. in order to evaluation the effect of heat stress on yield, yield component, and mopho-phenological traits of wheat, an experiment was conducted during 2010-2011 under normal (optimum sowing date) and heat stress (late sowing date) conditions on 11 wheat genotypes including yavaro...

BACKGROUND The current study investigates the anti-stress effects of clove (Eugenia caryophyllus) extracts (0, 200, 400, and 600 mg/kg) on serum antioxidant biomarkers, immune response, immunological organ growth index, and expression levels of acute phase proteins (APPs); ovotransferrin (OVT), ceruloplasmin (CP), ceruloplasmin (AGP), C-reactive protein (CRP), and serum amyloid-A (SAA) mRNA in ...

background: heat stress is one of the harmful factors present in many workplaces. it can lead to performance loss and low functionality of the labor force. therefore, the aim of this study was to evaluate exposure to heat stress and its consequent performance loss among workers functioning in indoor high-temperature workplaces. materials and methods: this descriptive, analytical study was condu...
