BACKGROUND/AIM Several types of the hepatitis C virus (HCV), with variations in different parts of the genome, have been isolated from different regions of the world. Based on heterogenic sequences in the isolated genome, HCV is classified into different genotypes and subtypes. Data on distribution of HCV genotypes in a certain region could be important to patient management. Therefore, this st...

the most common cardiovascular surgery in the world and iran as well, is cabg. one of the most important post-operative complication of this operation, that increase morbidity and mortality, is peri-operative mi. incidence of peri-operative mi in cabg operations is between 2.5 to 5.5%. in this study we determined the prevalence and incremental risk factors of peri-operative mi in 300 consequati...

background: l-carnitine has been demonstrated to confer cardiac protection against ischemia reperfusion injury in animals. this study evaluates the effects of l-carnitine administration on cardiac biomarkers after coronary artery bypass graft (cabg) surgery. methods: one hundred thirty-four patients undergoing elective cabg surgery, without a history of myocardial ischemia or previous l-carniti...

With the increasing demand for energy globally and need to reduce fossil fuels, paying attention renewable clean sources is necessary. Solar systems are viable among heat electricity generation. In this study, an Off-grid solar system was investigated by considering effect of climate conditions environmental factors such as dust on performance PV panels. Performance efficiency using PVsyst soft...

We review our variational quantum Monte Carlo (VMC) approach for evaluating the key quantities in the density functional theory of inhomogeneous many-electron systems, and describe the underlying simulation algorithm and its parallel implementation. We discuss the insights gained from our recent application of the method to the study of the density functional theory (DFT) of the strongly inhomo...
