INTRODUCTION Major depressive disorder (MDD) is often precipitated by life stress and growing evidence suggests that stress-induced alterations in reward processing may contribute to such risk. However, no human imaging studies have examined how recent life stress exposure modulates the neural systems that underlie reward processing in depressed and healthy individuals. METHODS In this proof-...

The authors examine the prevalence of acute traumatic dissociative responses in a group of 115 law enforcement officers involved in critical incidents. Law enforcement officers were retrospectively surveyed for the presence of dissociative symptoms at the time of the critical incident, as well as for the presence of acute stress symptoms and posttraumatic stress symptoms. Results show that 90% ...

Psychosocial stress is a potent activator of the hypothalamus-pituitary-adrenal (HPA) axis. While neuroendocrine stress responses are essential for the maintenance of homeostasis, evidence suggests that excessive activation of the HPA axis constitutes a risk for disease and psychopathology. The purpose of the present study was to assess the effect of cognitive-behavioral stress management train...

INTRODUCTION The occurrence of hyperglycemia in non-diabetics during development of acute coronary ischemia (ACI) indicates latent glucose metabolism disorder, or is a case of newly discovered diabetes mellitus (DM) as a result of stress. Acute coronary syndrome refers to a group of clinical syndromes caused by a sudden circulatory disorder in coronary arteries, resulting in the corresponding m...

Introduction. Stress reaction in deadly scenarios is a systemic response of human body to the impact extreme and acute psychotraumatic factors. The condition associated with complete or partial loss ability perform tasks can lead development post-traumatic stress disorder. Therefore, new effective means methods correction lethal force most urgent challenge for catastrophe medicine. objective es...

the aim of this study is to investigate antioxidant enzymes, oxidative stress biomarkers and the acute phase proteins levels for subclinical and clinical pregnancy toxemia and to determine the effect of early diagnosis on the success of curing. according to the results of clinical and biochemical parameters, from 39 ewes, 10 were healthy ewes (control group), 13 ewes had subclinical pregnancy t...

background. the major side effect of cisplatin, used in some tumours, is nephrotoxicity. reactive oxygen species and oxidative damage are the most important factors in cisplatin-induced acute renal failure. the main purpose of this study is to investigate the protective effects of crocin against cisplatin-induced acute renal failure and oxidative stress in rat. methods. in this study, animals w...

objective: exposure to traumatic stressors lead to activation of arousal responses mediated by serotonergic and noradrenergic systems and it may cause a change in numerous neurotransmitters and neuroendocrine systems. there is ample experimental and clinical evidence to suggest that ginkgo biloba extract is neuroprotective and has antioxidant properties and can restore stress-induced elevation ...
