The effect of jump exercise on middle-aged osteopenic rats was investigated. Forty-two 9-mo-old female rats were either sham-operated (Sham) or ovariectomized (OVX). Three months after surgery, the rats were divided into the following groups: Sham sedentary, Sham exercised, OVX sedentary, and OVX exercised. Rats in the exercise groups jumped 10 times/day, 5(More)
The role of stromal cell-derived factor-1α (SDF-1α) expressed in infarcted myocardium is unknown in humans. We examined whether SDF-1α produced in an infarcted myocardial lesion may play a role in left ventricle (LV) remodeling and dysfunction in patients with acute myocardial infarction (AMI). We measured SDF-1α levels in plasma obtained from aortic root(More)
BACKGROUND We recently showed that stromal cell-derived factor (SDF)-1α, a pro-inflammatory mediator, is produced in infarcted myocardium and is associated with left ventricular (LV) adverse remodeling and progressive dysfunction following acute myocardial infarction (AMI). The current study examined whether SDF-1α levels in the peripheral vein can provide(More)
AIM Although plasminogen activator inhibitor-1 (PAI-1) is abundantly expressed in infarcted myocardium, the pathogenic role of myocardial PAI-1 remains unknown. This study examined whether PAI-1 in the infarcted lesion contributes to coronary endothelial dysfunction and left ventricular (LV) dysfunction in patients with acute myocardial infarction (AMI).
