OBJECTIVES We tested whether intermittent standing or a combination of heel raising, squatting and hopping exercises was sufficient to prevent alteration in balance and gait following a 5-day bed rest. METHODS This cross-over design study was performed with 10 male subjects during 6° head down tilt: (a) with no countermeasure; (b) while standing 25 min per day; (c) during locomotion-like acti...

We present a rare case of avulsion fracture of the reflected head of rectus femoris. This occurred in a 13-year-old male footballer. Diagnosis was made with pelvic radiology and treatment was bed rest and analgesia.

Muscle biopsy has long been expected to be replaced by noninvasive biomarkers with diagnostic value and prognostic applications for muscle atrophy. Growing evidence suggests that circulating microRNAs (miRNAs) could act as biomarkers for numerous pathophysiological statuses. In the present study, our results showed that the serum levels of six muscle-specific miRNAs (miR-1/23a/133/206/208b/499)...

OBJECTIVES We tested whether intermittent short-radius centrifugation was effective for mitigating alteration in balance and gait following bed rest. METHODS Ten male subjects were exposed to 5 days of 6° head-down tilt bed rest with: (a) no countermeasure; (b) daily 1-g centrifugation for a continuous 30-min period; and (c) daily 1-g centrifugation for six periods of 5 min. During and after ...

─We describe a computer model of intracranial pressure (ICP) dynamics that evaluates clinical treatment options for elevated ICP during traumatic brain injury (TBI). The model uses fluid volumes as primary state variables and explicitly models fluid flows as well as the resistance, compliance, and pressure associated with each intraand extracranial compartment (arteries and arterioles, capillar...

Adaptation to spaceflight or head-down-tilt bed rest leads to hypovolemia and an apparent abnormality of baroreflex regulation of cardiac period. In a previous study, we demonstrated that both chronic (2 wk) head-down-tilt bed rest and acute induced hypovolemia led to similar impairments in spontaneous baroreflex control of cardiac period, suggesting that a reduction in plasma volume may be res...

background:infant mortality is often used as a standard measure of a population’s health. until cause of sudden infant death syndrome is unknown (sids), the best strategy to decrease sids, is programming to decrease facing with risk factors. the aim of this study was to find the sids risk factors among families during their child care in iran. the study is the first in iran to examine the risk ...

BACKGROUND Short-distance falls, such as from a bed, are often falsely reported scenarios in child abuse. In attempting to differentiate between abusive and nonabusive injury, knowledge of factors that affect injury risk in falls could prove useful. OBJECTIVES To assess the biomechanics associated with simulated short-distance falls in children (one fall scenario, without attempting to maximi...
