Right ventricular (RV) weight increases dependent on time after myocardial infarction (MI) and on MI size. The sequential changes in RV volume and hemodynamics and their relations to left ventricular (LV) remodeling after MI are unknown. We therefore examined the time course of RV remodeling in rats with LV MI. MI was produced by left coronary artery ligation. Four, eight, and sixteen weeks lat...

BACKGROUND & OBJECTIVE Rubella virus (RV) is one of the leading causes of childhood blindness in India. In this study we applied an optimized nested reverse transcription polymerase chain reaction (nRT-PCR) to detect RV in clinical specimens. METHODS nRT-PCR was optimized using total RNA extracted from standard strain of RV using nested sets of primers specific for E1 open reading frame. nRT-...

By comparing three expression vectors for the rabies virus (Rv) minigenome, we show that the characteristic of the Rv RNA is important for efficient rescue despite its not being crucial for replication. Moreover, we show that the coexpression of the viral proteins from helper Rv and Mokola virus could rescue the Rv minigenome while Rv-related European bat lyssavirus 1 could not, suggesting that...

Right ventricular (RV) function is an important determinant of prognosis in congenital heart diseases, pulmonary hypertension, and heart failure. Preventive sildenafil treatment has been shown to enhance systolic RV function and improve exercise capacity in a model of fixed RV pressure load. However, it is unknown whether sildenafil has beneficial effects when treatment is started in establishe...

three hundred and fifteen day -old chickens were used to test the relationship between oxygen-derived free radicals and the biochemical, hematological and pathological alterations(associtd with ascites). they were randomly divided into three experimental groups and ascites were developed in two groups of animals by exposing them to low temperature or administration of triiodothyronine (t3,), an...

This research studies TV commercial from cultural-conflict view point and tries to analyze mutual relation between parent-child generations. It applies signifier's method for reflecting TV commercials. Signifying qualitative method on the base of General signifies along with "first levels signifiers" and "Second level signifiers" obtained Symbolic displacement. This research shows TV commerci...

INTRODUCTION Right ventricular (RV) function has increasingly being recognized as an important predictor for morbidity and mortality in patients with pulmonary arterial hypertension (PAH). The increased RV after-load increase RV work in PAH. We used time-resolved 3D phase contrast MRI (4D flow MRI) to derive RV kinetic energy (KE) work density and energy loss in the pulmonary artery (PA) to bet...

The aim of this study was to use magnetic resonance imaging (MRI) to classify the morphological changes and remodeling of the right ventricle (RV) that occur in different clinical situations and that have an impact on RV function. Most literature has traditionally focused on the left ventricle (LV) and as a result, few studies analyze RV behavior and remodeling. The study evaluated all cardiac ...

BACKGROUND Analysis of right ventricular (RV) regional dysfunction by cardiac magnetic resonance (CMR) imaging in arrhythmogenic RV cardiomyopathy (ARVC) may be inadequate because of the complex contraction pattern of the RV. Aim of this study was to determine the use of RV strain and dyssynchrony assessment in ARVC using feature-tracking CMR analysis. METHODS AND RESULTS Thirty-two consecuti...

BACKGROUND Non-ischemic fibrosis (NIF) on cardiac magnetic resonance (CMR) has been linked to poor prognosis, but its association with adverse right ventricular (RV) remodeling is unknown. This study examined a broad cohort of patients with RV dysfunction, so as to identify relationships between NIF and RV remodeling indices, including RV pressure load, volume and wall stress. METHODS AND RES...
