Factor requirements for yeast and rat liver ribosomes were determined in several different reactions using either yeast or liver factors. In polymerization assays yeast ribosomes required a factor in addition to elongation factor 1 (EF-1) and elongation factor 2 (EF-2). The third factor (EF3) requirement was observed with EFs from either yeast or liver for both poly(U)-directed polyphenylalanin...
Introduction: Coronary artery bypass graft can Improve myocardial contractility and functional class in Ischemic heart disease. Materials & Methods: This study was done on 200 patient’s with CABG operation during 6 months. 142 patients were men and 56 patients were women with mean age 57.7 9.2 years (36-83). EF was measured by echocardiography before & 1 week after CABG, CCSFC evaluated be...
BACKGROUND The relationship between whole spectrum of Ejection fraction (EF) and cardioembolic stroke (CES) outcome has not been fully described yet. Notably, it remains unclear whether borderline EF (41∼49%) is related with poor outcome after CES. We sought to evaluate whether lower ejection fraction and borderline EF could predict the outcome in patients with CES. METHOD AND RESULTS We eval...
Method From July 2013 up to September 2014 four high risk patients with low EF below 30 %, concomitant mitral valve disease (3 pts), ventricular aneurism (1 pt), and severe coronary artery disease were operated using on pump beating heart technique. Al pts were first connected to the IABP through the femoral artery and then put on CPB machine with a double venous cannula in the superior and inf...
BACKGROUND Left ventricular (LV) remodeling following acute myocardial infarction (MI) is difficult to predict at an individual level although a possible interfering role of vascular function has yet to be considered to date. This study aimed to determine the extent to which this LV remodeling is influenced by the concomitant evolution of vascular function and LV loading conditions, as assessed...
The yeast translational elongation factor 3 (EF-3) stimulates EF-1 alpha-dependent binding of aminoacyl-tRNA by the ribosome. The requirement for EF-3 is unique to fungi; a functional analog has not been found in prokaryotes or other eukaryotes. We have isolated and characterized the structural gene, YEF3, that encodes EF-3. The YEF3 gene is present in one copy/haploid genome and is essential f...
Background and purpose: Nitrate contamination in aqueous solution has become an increasingly serious environmental problem. Hence, in this study removal of nitrate in aqueous solution was reviewed using electrocoagulation (EC) and electro-fenton (EF) processes for Fe electrodes. Materials and methods: In the present study, an EC and EF reactor in a lab scale to an approximate volume of 1 liter...
