background: organic nitrates relax all kinds of smooth muscle , not only vascular smooth muscle , a fact that has allowed the use of these drugs to treat many different aliments. objective.-the purpuse of this study was to examine prosepectively benefical effects , if any, of sublingual nitroglycerin on the pain of renal colic. design.- prospective , randomised , double blind, placebo- contoled...

Background and Purpose: Conventionally, the architecture of the artery wall is based upon the close-packed smooth muscle cells, endothelial and adventitial cells in both sides of internal elastic lamina (IEL). However, the adventitia and endothelium are now viewed as key players in vascular growth and repair. Recent work raises fundamental questions about the cellular heterogeneity of arterie...

Background and purpose: Atherosclerosis is a major cause of death in adults in most countries. Many studies have focused on the protective role and anti-inflammatory properties of adiponectin but its role in calcification has been less studied. Studies that could determine the causes and mechanisms of calcification could be of great value. The aim of this study was to investigate the effects...

Background and Objective: Atheroma formation and progression of atherosclerosis are dependent on the expression of bone matrix proteins and regulatory factors such as osteonectin in the vessel walls. Studies have shown that consumption of Trans fatty acids increase risk of cardiovascular diseases. In this study, the effect of elaidic acid on osteonectin gene expression as one of the vascular ca...

Background and purpose: Vascular calcification is an important factor in pathogenesis of atherosclerosis. Studies have shown that alkaline phosphatase increases vascular calcification. Here we investigated the effect of gallic acid on alkaline phosphatase gene expression in vascular smooth muscle cells (VSMCs). Materials and methods: In this experimental study humans aorta VSMCs were incubated...

Purpose: To present a patient with interaconal orbital angioleiomyoma. Case Report: A 22-year-old woman presented with painless slowly progressive proptosis. CT and MRI demonstrated a well-defined Interaconal globe size mass (inferomedially). It was isointense in T1 and T2 weighted and homogenously enhanced by Gadolinium. During the surgery, the tumor was excised via a lateral orbitotomy approa...

LOX-1 is a class E scavenger receptor that mediates the uptake of oxLDL by vascular cells. LOX-1 is involved in endothelial dysfunctions, monocyte adhesion, the proliferation, migration, and apoptosis of smooth muscle cells, foam cell formation, platelet activation, as well as plaque instability; all of these events are critical in the pathogenesis of atherosclerosis. These LOX-1-dependent bio...
