background occult hepatitis b infected (obi) patients cannot eradicate hepatitis b virus (hbv)-dna from their liver and peripheral blood, completely. objectives the main aim of this study was to investigate the rate of hla-a2 expression on peripheral blood mononuclear cells (pbmcs) of patients with obi. materials and methods in this experimental study, intensity of hla-a2 was measured on the pb...

The aim of this paper is to develop a mathematical model for studying the non-Newtonian flow of blood through a stenosed arterial segment. Power law fluid represents the non-Newtonian character of blood. The hemodynamic behavior of the blood flow is influenced by the presence of the arterial stenosis. The problem is solved by using analytical techniques with help of boundary conditions and resu...

In atrial fibrillation, exercise capacity is often reduced. This is usually ascribed to a decreased cardiac output as compared with sinus rhythm. Very few studies, however, have focused on changes in the peripheral blood flow during atrial fibrillation as a potential mechanism for exercise limitation. The aim of the present study was to determine the effect of conversion of atrial fibrillation ...

The effect of i.v. administration of the nitric oxide synthase (NOS) inhibitor N(omega)-nitro-L-arginine (L-NNA) on tumor blood flow compared with normal tissue blood flow was studied in anesthetized BD9 rats bearing subcutaneous P22 carcinosarcomas. Blood flow was measured by the tissue uptake of radiolabeled iodoantipyrine. The reversibility of blood flow changes was tested by subsequent admi...

Dear Editor-in-Chief, A recent article published in the Journal of Human Kinetics (Aráujo et al., 2014) described a postexercise hypotensive effect in hypertensive subjects after resistance exercise with blood flow restriction. The aim of this letter is to endorse the importance of further research on post-exercise hypotensive effect as a result of resistance training with blood flow restrictio...

In the present work a two fluid model for blood flow through abnormally constrictedhuman artery (stenosed artery) has been developed. The model consists of a core region of suspensionof all erythrocytes assumed to be micro-polar fluid so as to include the micro-structural effects inaddition to the peripheral-layer viscosity effects, and a peripheral plasma layer free from cells of anykind of Ne...

The control of tissue blood flow is a dynamic process exemplified by the interaction among physical, chemical, and electrical events occurring within the vessel wall and between the vasculature and tissue parenchyma. The range of blood flow control achieved in vivo is illustrated by functional hyperemia in exercising skeletal muscle: maximal flow can exceed resting values by more than 50-fold. ...

The analogue, l-sarcosine-8-alanine-angiotensin II, a specific competitive antagonist of the vascular action of angiotensin II in the rat, blocked the decrease in renal blood flow after a single intrarenal injection of angiotensin II but not after an injection of norepinephrine in normal dogs, in a sodium-depleted dog, and in a dog with thoracic vena caval constriction. Infusion of the analogue...
