Introduction: The aim of this study was evaluation the effects of bilateral carotid artery occlusion on cochlear oxidative stress and hearing status in rat. Methods: The rats were divided into two sets. First set used for electrophysiological recording (click and 4 kHz tone burst ABR and EcochG) at day before surgery and 1st, 4th and 7th days after surgery. Animals of second set that used for ...

Introduction:In this study, a non-invasive method based on consecutive ultrasonic image processing is introduced to assess time rate changes of the carotid artery wall displacement, velocity and acceleration in the longitudinal direction. The application of these parameters to discriminate healthy and atherosclerotic arteries was evaluated. Methods:Longitudinal displacement rate of common ...

Introduction: Nitroglycerin is a fast-acting drug that rapidly dilates coronary arteries and thus increases blood flow to these vessels, and increases the blood flow through the lateral vessels to low blood areas. It also reduces both end diastolic pressure and volume of the left ventricular. However, the effect of nitroglycerin on the circulation hemodynamic is not known. Caro...

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

Objective: We report the “sheath pull-through technique” for stenting of common carotid artery stenosis (CCAS).
