abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...

Abstract Background: Congenital heart defects are known as the state that comes from birth and influences on structure and function of baby's heart, The different types of defects can range from mild (e.g., a small hole between the heart chambers) to hard (like a flaw or weakness in a part of the heart). Method: This article is a review article in which the articles published in Farsi and Engli...

​Introduction: Different factors are effective in detecting heart abnormalities. The greater the number of these factors, the greater the uncertainty in the detection of heart abnormalities. In the uncertainty condition in response of prediction model, the fuzzy systems are one of the most effective methods for generating an acceptable response. Method: In this applied study, 3240 records rela...

Background: In patients who undergoing PCI, association between right ventricular function and outcome of the procedure remained unclear. The present study aimed to determine association between echocardiography findings of systolic right ventricular function and functional status of patients following PCI. Methods: In a cross-sectional study conducted at Imam Ali hospital and heart center in ...

BACKGROUND Little is known about the effect of heart cell transplantation into the dilated cardiomyopathic myocardium. This study was designed to evaluate the effect of heart cell transplantation into dilated cardiomyopathic hamsters. METHODS AND RESULTS Ventricular heart cells were isolated from 4-week-old BIO 53. 58 hamsters and cultured for 2 weeks before transplantation. The cells were la...

in this study a new minimum lumped electrical model of total circulatory system through numerical solutions to approximate the response of the human circulatory system was presented. among five existent ventricular elastances as activity function of heart pumps, a more accurate model was chosen as well as the operation of baroreflex system to accommodate variations in heart rate and systemic va...

Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...
