objective: the purpose of the present study was to compare response inhibition and cognitive appraisal in clients with acute stress disorder, clients with posttraumatic stress disorder, and normal individuals . method:  this  was a comparative study. the sample consisted of 40 clients with acute stress disorder, 40 patients with posttraumatic stress disorder, and 40 normal individuals from maza...

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...

chemotherapeutic agents used in patients with cancer cause to generate the enormous amounts of free radicals associated with cell injury. in this study we assess the effects of chemotherapy regimen on oxidant/antioxidant status in patients with acute myeloid leukemia (aml). 38 newly diagnosed patients with acute myeloid leukemia were recruited in this study. all patients received cytarabine and...

objective(s):therapies with high levels of oxygen are commonly used in the management of critical care. however, prolonged exposure to hyperoxia can cause acute lung injury. although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (hali).   materials a...

objective(s): due to the prevalence and pervasiveness of stress in modern life and exposure to both chronic and acute stresses, it is not clear whether prior exposure to chronic stress can influence the impairing effects of acute stress on memory retrieval. this issue was tested in this study. materials and methods: adult male wistar rats were randomly assigned to the following groups: control,...

introduction: current study examined the possible role of the central nucleus of amygdala (cea) transient inactivation on the metabolic and hormonal disturbances induced by acute electro foot shock stress in female rats. considering the differences between female and male in responses to stress, this study attempts to reveal possible mechanisms underlying these differences. methods: uni- or bil...

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: 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...

Objective(s): Due to the prevalence and pervasiveness of stress in modern life and exposure to both chronic and acute stresses, it is not clear whether prior exposure to chronic stress can influence the impairing effects of acute stress on memory retrieval. This issue was tested in this study. Materials and Methods: Adult male Wistar rats were randomly assigned to the following groups: control,...

introduction: it is known that acute and chronic stress induce hormonal and neuronal changes which affecting both pain threshold and nociceptive behaviours. orexin plays an important role in modulation of pain and stress. considering pain modulation during stress and the role of orexin in pain and stress, orexin might be involved in pain modulation during stress.we evaluated the involvement of ...
