the effects of some histaminergic agents were evaluated on stress- induced immunosuppression in immunized nale rats. in rat immunized with sheep red blood cells ( srbcs). restraint stress (rs) prevented the booster-induced rise in anti-srbc antibody titre and cell immunity response. intracerebroventicular (i.c>v) injection of histamine (150 µg/rat) induced a similar effect with rs. pretreatment...

in this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. geometry of sheet strip is pre-estimated by a shape function. then longitudinal, transversal and shear strains have been calculated. using both the levy-mises and the prandtl reuss equations, and also considering the bauschinger effect, stress distributions have b...

conclusions in the setting of acute left ventricular function depression in hocm, a comprehensive differential diagnosis should be established. treatment should be based on hemodynamic changes. after recovery, the prognosis is related to hocm. case presentation we present a unique case where tks occurred in a middle-aged male patient with hypertrophic obstructive cardiomyopathy (hocm) without a...

INTRODUCTION Chronic stress is known to have negative effects on reproduction, but little is known about how it affects the sexual response cycle. The present study examined the relationship between chronic stress and sexual arousal and the mechanisms that mediate this relationship. AIM The aim of this study is to test the relationship between chronic stress and sexual arousal and identify me...

In this paper we introduce ViRUS: Virtual function Replacement Under Stress. ViRUS allows the runtime system to switch between blocks of code that perform equivalent functionality at different Quality-ofService levels when the system is under stress — be it in the form of scarce energy resources, temperature emergencies, or various sources of environmental and process variability — with the ult...

Reactive oxygen metabolites generated during normal metabolism and metabolism stimulated by xenobiotics can enter into reactions that, when uncontrolled, can impair performance of dairy cows. Direct effects include peroxidative changes in membranes and other cellular components. Indirectly, competitive consumption of reducing equivalents can interfere with important metabolic functions and dive...

Wistar strain albino rats of either sex were subjected to acute noise stress (3000 Hz at > 97 dB) for 30 minutes. Carbon clearance test was conducted in noise stressed animals immediately after the stress period. Significant (P < 0.001) increase of the clearance constant K was observed in stressed animals compared to the controls, indicating increased phagocytic activity of the reticuloendothel...

The ovary is the main regulator of female fertility. Changes in maternal health and physiology can disrupt intraovarian homoeostasis thereby compromising oocyte competence and fertility. Research has only recently devoted attention to the involvement of dicarbonyl stress in ovarian function. On this basis, the present review focuses on clinical and experimental research supporting the role of d...

Recent studies have reported memory deficits and reduced hippocampal volumes in posttraumatic stress disorder (PTSD). The goal of the current research was to use functional neuroimaging and a validated explicit memory paradigm to examine hippocampal function in PTSD. We used positron emission tomography (PET) and a word-stem completion task to study regional cerebral blood flow (rCBF) in the hi...
