s:2728:"Background: Rapid industrialization, environmental pollution, changing living conditions and unfavourable working conditions cause stress to the people which may play an important role in developing several disorders. Sress is one of the most important health and social problems. Physchological stress has long been suspected of having an important impact on infertility . There is a grea...

objectives: this study sought to assess the level of stress in general dentists in the 2nd district of tehran city in 2014 to find out the stressors and suggest strategies to overcome them. methods: this descriptive, analytical, cross-sectional study was conducted on 130 general dentists from the 2nd district of tehran city selected via weighted randomization. level of stress was assessed using...

introduction: stress is defined as any environmental change that disturbs the maintenance of brain homeostasis. stress leads to production of pro-inflammatory cytokines that provoke neurodegenerative disorders. in the present study, we investigated the effects of dalteparin on hippocampal neuronal death induced by chronic stress in rats. methods: the study was carried out on 60 adult male wista...

in order to evaluate drought tolerance of some aegilops triuncialis ecotypes a factorial experiment based on a completely randomized design was conducted under non-stress and drought stress (irrigation until 50% of heading) condition in the greenhouse of mohaghegh ardabili university in 2012. drought tolerance and susceptibility indices for grain yield were calculated and principal component an...

in order to evaluate the best drought resistance indices in sugar beetgenotypes, an experiment was conducted in 2002 using a split- plot design within randomized complete block design with three replications at the research farm, shiraz-zarghan. the main plots consisted of three irrigated regimes: non stress, 75% (mid stress) and 50% (intense stress) non stress and the ten genotypes as the sub ...

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...

experimental study of the cyclic behavior of unsaturated materials is more complex than that of the saturated materials due to the required equipment, experience and time. furthering investigations in the field of unsaturated materials is necessary to better understand its complexity and sensitivity of unsaturated cyclic parameters to different determinants such as suction path, stress path, lo...

background: overwhelming life experiences can trigger stress disorders including acute stress disorder (asd) and post-traumatic stress disorder (ptsd). the objective of this study was to investigate the frequency of and predictive factors for asd and ptsd in snakebite victims. methods: in this study, snakebite victims who were admitted to mashhad medical toxicology centre, imam reza hospital, i...
