A marked functional polarity of endothelial cells as well as an asymmetry of the vascular wall in response to vasoactive compounds is well established. Therefore, we investigated the polarity of endothelium-derived relaxant factor (EDRF) release from native endothelial cells, its diffusion characteristics, and its dilator effects on inner and outer muscle layers of the vascular wall in isolated...
ABSTRACT Among the causes of ascites, there is two kinds, including cirrhotic and malignant ascites that conventional diagnostic method for them is Paracentesis. This method is invasive and time consuming, however sonography is an easy and available method for providing valuable results in a short period of time. The aim of this study is survey of valuability of gallbladder wall so...
Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...
Yeast cell walls are critical for maintaining cell integrity, particularly in the face of challenges such as growth in mammalian hosts. The pathogenic fungus Cryptococcus neoformans additionally anchors its polysaccharide capsule to the cell surface via alpha(1-3) glucan in the wall. Cryptococcal cells disrupted in their alpha glucan synthase gene were sensitive to stresses, including temperatu...
According to construction scheme of some weak surrounding rock large span double and multi-arch tunnel works, finite element value simulation method is adopted to research weak surrounding rock deformation characteristic, anchor bolt mechanics characteristic, preliminary support and secondary lining structure mechanical characteristics, etc, and the research result shows that: repeatedly distur...
Sungun Copper Mine is located in an area with a high level of seismic hazard. Most recently, the Ahar-Varzeqan earthquake with a magnitude of 6.2 on Richter scale occurred on August 11, 2012; at a distance about 40 kilometers away from the mine. Nevertheless, the seismic stability of the final pit wall has not been comprehensively reviewed. In this research, the southwestern wall of the final p...
Shear-induced migration of red blood cells (RBCs) is a well-known phenomenon characterizing blood flow in the small vessels (micrometre to millimetre size) of the cardiovascular system. In large vessels, like the abdominal aorta and the carotid artery (millimetre to centimetre size), the extent of this migration and its interaction with secondary flows has not been fully elucidated. RBC migrati...
in the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. in 2-d analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...
background: in intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. this study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...
