Staphylococci are a versatile genus of bacteria that are capable of causing acute and chronic infections in diverse host species. The success of staphylococci as pathogens is due in part to their ability to mitigate endogenous and exogenous oxidative and nitrosative stress. Endogenous oxidative stress is a consequence of life in an aerobic environment; whereas, exogenous oxidative and nitrosati...
4 ABSTRACT Background: Trauma is a major cause of death and disability. Adverse events, such as prolonged prehospital time, hypoxia, hypotension and/or hyperventilation have been reported to correlate to poor outcome. Adequate cortisol levels are essential for survival after major trauma. In hypotensive critically ill patients, lack of sufficient amount of cortisol can be suspected, and a conce...
Space flight imposes upon man many stresses; i.e., thermal, irradiation, sensory deprivation, acceleration (exit), deceleration (re-entry), and so forth. Some of these stresses, such as sensory deprivation, cannot be adequately studied within the earth's atmosphere whereas others, such as acceleration and deceleration, lend themselves more easily to experimentation. Although the sympathoadrenal...
Head-up tilt (HUT) induces a reduction in preload, which is thought to be restored through sympathetic venoconstriction, reducing unstressed volume (V(u)) and venous compliance (VeC). In this study, we assessed venous inflow and outflow responses and their reproducibility and determined the relation with autonomic function during HUT. Eight healthy non-pregnant women were subjected to 20 degree...
objective(s): stress induces many homeostatic aberrations which are followed by lifelong allostatic responses. epilepsy is developed or influenced by different environmental factors, i.e. prenatal stress which makes many contradictory developmental changes in seizure threshold and intensity. we investigated the potential seizure response of the rat offspring to prenatal stress; the stress which...
