Hydrocephalus is the most common developmental disability and leading cause of brain surgery for children. Current treatments are limited to surgical intervention, as the factors that contribute to the initiation of hydrocephalus are poorly understood. Here, we describe the development of obstructive hydrocephalus in mice that are null for Wrp (Srgap3). Wrp is highly expressed in the ventricula...

background: longer survival after the total repair of the tetralogy of fallot increases the importance of late complications such as right ventricular dysfunction. this is a prospective study of the right ventricular function in totally corrected tetralogy of fallot patients versus healthy children. methods: thirty-two healthy children were prospectively compared with 30 totally corrected tetra...

Recognition of the natural history and responsible leading factors for regression of left ventricular hypertrophy after successful renal transplantation are very important. The aim of this study was to assess the regression of left ventricular hypertrophy after successful renal transplantation among uremic patients. In this study 27 uremic patients (18 males and 9 females) with an average a...

Abstract Objective Cardiac dysfunction is a major cause of death in patients with beta thalassemia. In these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. Left ventricular ejection fraction was measured in major beta thalassemia (β-Th) patients to detect the rela...

the optimal treatment method for right ventricular failure after valve surgery complicated by a low cardiac output has not been determined, although several case reports have been published on patients with ventricular failure and arrhythmia who were bridged to cardiac transplantation using biventricular or left ventricular assist devices. this case series illustrates successful circulatory sup...

HF-1 b, an SP1 -related transcription factor, is preferentially expressed in the cardiac conduction system and ventricular myocytes in the heart. Mice deficient for HF-1 b survive to term and exhibit normal cardiac structure and function but display sudden cardiac death and a complete penetrance of conduction system defects, including spontaneous ventricular tachycardia and a high incidence of ...

A model of voluntary exercise, in which rats are given free access to a running wheel over a 14-week period, led to left ventricular hypertrophy. To test whether the hypertrophic response to exercise was uniformly distributed across the ventricular wall, single ventricular myocytes were isolated from the sub-epicardium (EPI) and sub-endocardium (ENDO) of exercised rats and from sedentary rats f...

stract-Regional differences in the restitution of action tential duration may be arrhythmogenic. Though such a fference exists at the Purkinje-ventricular interface, restitution netics have not yet been defined between coupled Purkinje and ntricular cells. Thus, the purpose of this study was to termine the effects of coupling on restitution in Purkinje and ntricular cells. DiFrancesco-Noble and...

Objective(s): This study aimed to evaluate the protective effects of total flavonoid extract from Coreopsis tinctoria Nutt.(CTF)against myocardial ischemia/reperfusion injury (MIRI) using an isolated Langendorff rat heart model. Materials and Methods: Left ventricular developed pressure (LVDP) and the maximum rate of rise and fall of LV pressure (±dp/dtmax) were recorded. Cardiac injury was as...
