background: early clinical investigations indicate that an infusion of autologous bone-marrow cells into the infarct-related coronary artery is feasible after acute myocardial infarction. there is increasing evidence that cell transplantation may improve the perfusion and contractile function of the ischemic myocardium . the present study reports primarily the safety of intracoronary bone marro...

objective(s):this study focused on the effect of waterpipe smoke exposure toxicity on the structure of albino rat’s ventricular tissue and their recovery. materials and methods: albino rats were divided into three groups: control, flavored, and unflavored. the control group was exposed to normal air while the flavored and unflavored groups were exposed to waterpipe smoke for a period of 90 days...

the disease of thalassemia major requires mangement by repeated transfusions of packed cell and iron chelators such as deferoxamine. today, serum ferritin is used for estimation of adequacy of the management. as the most morbidities and mortalities of the disease are the consequences of cardiac complications. echocardiography is periodically periodically performed along with the management. in ...

experimental and clinical studies have shown that intracoronary transplantation of autologous bone marrow mesenchymal stem cells (bmscs) has resulted in regenerated infarcted myocardium and improved left ventricular (lv) function.the aim of this pilot study was to assess the benefical effectsof intracoronary transplantation of bmsc in patients with oldmyocardial infarction (omi). autologous bms...

the right ventricle (rv) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (lv), so it cannot be described as a simple geometric form and achromatic physiology. as an inference from this fact, in the present review, we aim to describe rv structure including the embryology, anatomy, and physiology and present a functional, hemody...

ventricular fibrillation is the cause of the most sudden deaths. the recent findings have clearly proved the correlation between the slope of restitution curve with ventricular fibrillation. cellular automata is a powerful tool for simulating complex phenomena in a simple language. in this paper, a simple model is proposed for the simulation of the property of restitution in a single cardiac ce...

BACKGROUND: Bone marrow-derived mesenchymal cellscan transdifferentiate into Cardiomyocyte cells and improveheart function after transplantation. Since biomaterials canimprove the cell retention in the site, cell survival and differentiation,heart tissue engineering is now being explored as anapplied solution to support cell-based therapies and increasetheir efficacy for myocardial diseases. Ch...

arrhythmogenic right ventricular dysplasia/cardiomyopathy (arvd/c) is a congenital cardiac disease with myocardial involvement, most probably right ventricular (rv) dysfunction, accounting for 20% of sudden cardiac deaths. characterized by the fibro-fatty infiltration of the rv free wall, arvd/c presents in adolescents with ventricular arrhythmias and heart failure symptoms and as biventricular...

the aim of this study is to evaluate how far lempel-ziv complexity (lzc) of the binary symbolic sequences resulting from static or dynamic transformation (partitioning first-order difference) of the short-term electrocardiogram (ecg) signals (only 2 seconds duration) has the  potential in discriminating normal and ventricular tachycardia/ventricular fibrillation (vt/vf) subjects. the statistica...
