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...

triggering of acute myocardial infarction   m. salehian [1]     abstract     coronary heart disease (chd) is the leading cause of death in the united states each year about 450.000 people die from chd, and 1.000.000 experience an initial or recurrent coronary event. plaque rupture and it's its subsequent thrombosis at the site of the plaque rupture is the most common underlying pathophysio...

objective(s): exposing to stress may be associated with increased production of reactive oxygen species (ros). therefore, high level of oxidative stress may eventually give rise to accumulation of oxidative damage and development of numerous neurodegenerative diseases. it has been presented that brain-derived neurotrophic factor (bdnf) supports neurons against various neurodegenerative conditio...

background: the effect of heat stress on physiologicalparameters has been well documented. however, there arereports of a genetic based heat tolerance in some sheep breeds.objectives: the aim of the present study was to monitor thephysiological responses of an iranian fat-tailed breed againstheat stress and an acute stress insult. methods:atotal numberof 15 fall-born ram lambs were selected and...

background: polycyclic aromatic hydrocarbons (pahs) such as naphthalene (nap) are organic pollutants that have spread widely in littoral marine ecosystems. we aimed to study the effect of acute and prolonged exposure to naphthalene (nap) on plasma cortisol and thyroid levels in mature and immature liza klunzingeri mulet. methods: in acute stress experiment, the treatment group received 2μl g-1 ...

Previous studies indicated that stress and glucocorticoids have modulatory effects on acute pain. The aim of present study was to determine the interaction between stress and glucocorticoids with activation of voltage dependent Ca2+ channel on modulation of acute pain in mice. Male albino mice (25-30 g) were used for this experiment. Tail flick and hot plate were used for evaluation of analgesi...
