Background: Hindlimb Unloading (HLU) is used to simulate microgravity in rats and has been shown to decrease contractile response in the abdominal aorta. The aim of present study was to investigate the contractile responses of smooth muscle of thoracic aorta following acute and chronic microgravity treatment. Methods: Male adult rats (Wistar) were subjected to HLU for 3 and 20 days t...
INTRODUCTION The primary objectives of this study were to evaluate contractile and non-contractile content of lower leg muscles of boys with Duchenne muscular dystrophy (DMD) and determine the relationships between non-contractile content and functional abilities. METHODS Lower leg muscles of thirty-two boys with DMD and sixteen age matched unaffected controls were imaged. Non-contractile con...
The contractile vacuole of the fresh water protozoan Paramecium is a membrane-bound vesicle that expels excess cytosolic water, acquired osmotically, through its periodic exocytotic activity. The in vitro contractile vacuole, isolated in a small amount of cytosol from the Paramecium cell and confined under mineral oil, showed periodic rounding and slackening at regular intervals for an extended...
ATP-sensitive potassium (KATP) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. There has been considerable interest in exploring KATP channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. The purpose of this study was to synthesize 3,3,6,6-tet...
Numerical simulations and linear stability analyses of expanding cellular monolayers suggest cell–substrate friction is responsible for fingers at the edge. A critical contractile stress characterises wetting-dewetting; dewetting inhibits fingering.

objective: diabetes is an important risk factor for cardiovascular events. the great percent of morbidity in patients with diabetes is due to endothelial dysfunction. the present study investigated the effects of hydroalcholic extract of nigella sativa (n. sativa) on contractile and dilatation response of isolated aorta in streptozotocin (stz)-induced diabetic rat. materials and methods: rats ...
artemisia species, growing in almost all the northern hemisphere, is used in folk medicine of some countries as a remedy for hypertension. since some cardiovascular disorders including hypertension are accompanied with altered responsiveness of vascular alpha-adrenergic receptors, the effect of aqueous artemisia annua extract (100 and 200 mg kg-1) on a1-adrenoceptor agonist-induced contraction ...
