Vinculin- and caldesmon-immunoreactive forms and actin isoform patterns were studied in samples of normal and atherosclerotic human aorta. After removal of adventitia and endothelium, the remaining tissue was divided into three layers: media, muscular-elastic (adjacent to media) intima, and subendothelial (juxtaluminal) intima. In media of normal aorta, meta-vinculin accounted for 41.0 +/- 0.9%...

endothelial dysfunction and carotid intima-media thickness are 2 indicators of subclinical cardiovascular disease. the aim of study was to analyze brachial flow mediated dilation(fmd)and carotid intima media thickness (cimt)in patients with coronary artery disease, and investigate the relationship between endothelial function, cimt and coronary artery disease risk factors.56 men and women aged ...

OBJECTIVE Previously we found dramatic strain-dependent differences in a low flow model of vascular remodeling. Specifically, intima formation in the left common carotid artery was approximately 30-fold greater in SJL compared to C3HeB/Fe (C3H/F) mice. We hypothesized that a few genes control intima formation in response to low flow. A C3H/F and SJL backcross resulted in broad range of N2 intim...

To investigate the effects of fasting and postprandial glucose on endothelial cell function and intima-media thickness, we studied 60 men with cardiovascular risk factors. Postischemic, endothelium-dependent vasodilatation was measured after 3 minutes of ischemia at the radial artery with high-resolution echo tracking. Common carotid artery intima-media thickness was measured by B-mode ultrasou...

Although the etiology of varicose veins remains unknown, recent studies have focused on endothelial cell integrity and function because the endothelium regulates vessel tone and synthesizes many pro- and anti-inflammatory factors. The aim of this study was to investigate the evidence involving the endothelium in the development of varicose vein disease. In addition, tissue remodeling was invest...

Abstract Beyond the Intima Media Thickness assessment: measurement of overall echogenicity (GSM) Carotid Complex shows a positive correlation with Arterial Stiffness hypertensive patients. According to latest ESC guidelines on CVD prevention (2021) arterial stiffness still has role in predicting future risk and defining patients’ level. However, significative difficulties make widespread evalua...

Objective: A magnesium deficiency is known to be involved in many abnormalities in the post-menopausal women. Previous studies proposed that magnesium (Mg) might prevent atherosclerosis. In this study the efficacy of serum magnesium level and its relation with carotid intima media thickness (CIMT) in post-menopausal women was evaluated. Methods: Eighty Iranian Postmenopausal women were included...

Brachiocephalic arteries in quails are large arteries which are arising separately from the aortic arch. The aim of the present study was to determine the histomorphometric aspects of brachiocephalic arteries in the Japanese quail. The different layers of the brachiocephalic artery were studied quantitatively in 10, 20 and 60 days-old Japanese quail; (n = 6) and both sexes. Luminal diameter, th...

Introduction: Arteries are made up three layers; tunica intima, tunica media, and tunica adventitia. However, in some part of the artery this structure may change. The greatest change occurs at the junctions and bifurcations. In this regard, we decided to study the renal artery bifurcation just where the renal arteries divide into smaller arteries before entering the kidney. Methods: The struc...

Objective(s): Atherosclerosis is an important risk factor for coronary heart disease. Neuropeptide Y (NPY) and its receptors, located in peripheral tissue such as white adipose tissue, have been linked to obesity and fat storage. The role of NPY in atherosclerosis has not yet been fully studied, so this study was conducted to further investigate the effect of BIIE 0246, an NPY receptor antagoni...
