The prenatal stress syndrome: Current status
Psychoneuroendocrinology, 1984Exposure of female rats to stressors during the last week of pregnancy results in a selective feminization and demasculinization of adult sexual behaviors in the male offspring. No behavioral abnormalities are detectable in the female offspring, and reproductive morphological structures appear normal in both sexes.

Current Studies on Oxidant Stress in Dialysis
Blood Purification, 2003Breath ethane measurements in hemodialysis indicate that a portion of these patients suffer increased oxidant stress, consistent with findings using other methods for oxidant stress determination. Loosely-bound iron definitely appears in the bloodstream when substantial doses of IV iron are administered, since transferrin is fully saturated, but our ...

Stress fractures: current concepts.
American Journal of Roentgenology, 1992Stress fractures are extremely common lesions that occur in specific areas and are related to specific activities. They are caused by increased muscular activity on bones that are not yet ready to take the increased pull of the involved muscles. The insufficiency type of stress fractures found in patients with bone of diminished mineral content is ...

Supersaturation induced by current stressing
Scripta Materialia, 2011Current stressing results in electromigration and thus separation of metal atoms in an alloy. The present study reports that current stressing also induces the supersaturation of alloying elements. An in situ scanning electron microscopy/energy-dispersive spectroscopy analysis revealed that the dispersed Sn phase of 95Pb–5Sn solder in a 95Pb–5Sn/63Sn ...

The Current Evidence for Acute Stress Disorder
Current Psychiatry Reports, 2018The aim of this review is to provide a summary of the current evidence pertaining to the course of acute and chronic posttraumatic stress, the diagnosis of acute stress disorder (ASD), and treatment of acute stress disorder and prevention of posttraumatic stress disorder (PTSD).Although acute stress disorder was introduced partly to predict subsequent ...

A ZERO-CURRENT SWITCHING PWM FLYBACK CONVERTER WITH LOW CURRENT STRESS
Journal of Circuits, Systems and Computers, 2008An actively current clamped zero-current switching (ZCS) flyback converter is proposed in this paper. ZCS condition is obtained for all transistors for reducing switching loss and electromagnetic interference. With the current clamping technique, current stress of the converter is low.

Stress Ulcers: Current Understanding of Pathogenesis and Prophylaxis
Drug Intelligence & Clinical Pharmacy, 1988Stress-related gastrointestinal bleeding is known to occur in approximately 25 percent of untreated seriously ill patients, but with appropriate prophylaxis is largely preventable. Since the treatment of stress bleeding is generally unsatisfactory and has a high mortality, routine prophylaxis should be instituted for susceptible ...

Stress fractures: Current concepts
Skeletal Radiology, 19781. Stress fractures result from muscular activity on bones rather than from direct impact upon them. 2. The fatigue variety of stress fracture occurs in normal bone when abnormal muscular tension or torsion is placed upon it. 3. The insufficiency type of stress fracture results when normal muscular stress is placed upon a bone with deficient elastic ...

Stress Fractures: Current Concepts
2017A stress fracture is a partial or complete solution of continuity in the bone, which can result from excessive repeated loads at submaximal intensity, resulting in greater bone reabsorption without equivalent bone ingrowths. Stress fractures in football players are particularly difficult to diagnose and treat, because of the specificity of the modality
