Abstract The predictors of favorable clinical response to aortic valve replacement (AVR) in stenosis (AS) are still insufficiently defined. increased LV afterload AS affects the interpretation majority systolic indices, which load-dependent. estimation myocardial work (MW) is a newly developed approach, which, allowing correction global longitudinal strain (GLS) for afterload, gives more adequa...
In order to understand the pathogen’s genetic diversity and dynamics of fungal populations, 34 rice blast isolates collected from various blast endemic areas of India were analyzed using Magnaporthe grisea genome specific microsatellite markers (MGM) and repeat element based Pot2 primer. All the blast isolates showed average pair wise similarities in the range of 0.15 to 0.9 and suggested the l...
In humans, tendon vibration evokes illusory sensations of movement that are usually associated with an excitatory tonic response in muscles antagonistic to those vibrated (antagonist vibratory response, AVR), i.e., in the muscle groups normally contracted if the illusory movement had been performed. The aim of the present study was to investigate the relation between the parameters of the illus...
VE (Virtual Environment) provides the three dimensional visual interactive environment for the new generation the fourth generation natural HCI (Human Computer Interaction) system. Modeling the virtual objects is the key to build VE. The paper focuses on the theory, algorithms and core techniques for AVR (From Actual Reality to Virtual Reality) modeling of virtual environment. Based on the inte...
هدف از انجام این پروژه ارائه روشی برای اندازه گیری روی خط تمامی پارامترهای ژنراتور سنکرون می باشد. این پارامترها، شامل پارامترهای دینامیکی و گذرای ژنراتور سنکرون می باشند. در این پایان نامه، برای ایجاد اختلال دینامیکی در ژنراتور، به جای اینکه avr را از مدار خارج کرده و به صورت دستی در ولتاژ تحریک ایجاد اختلال کرد، تغییر در سیگنال مرجع avr، اعمال می شود و تخمین پارامترها، برای سیستم به هم پیوسته...
PURPOSE We sought to evaluate the clinical usefulness of decision making by a multidisciplinary heart team for identifying potential candidates for transcatheter aortic valve implantation (TAVI) in patients with symptomatic severe aortic stenosis. MATERIALS AND METHODS The multidisciplinary team consisted of two interventional cardiologists, two cardiovascular surgeons, one cardiac imaging sp...
BACKGROUND Sutureless aortic valve replacement (SU-AVR) is an innovative approach which shortens cardiopulmonary bypass and cross-clamp durations and may facilitate minimally invasive approach. Evidence outlining its safety, efficacy, hemodynamic profile and potential complications is replete with small-volume observational studies and few comparative publications. METHODS Minimally invasive ...
BACKGROUND Transcatheter aortic valve implantation (TAVI) has been an alternative to conventional aortic valve replacement (AVR) in old and high risk patients. The goal of this study is to compare the early outcomes of conventional AVR vs. TAVI in high risk severe AS patients. METHODS From January 2008 to July 2012, 44 high risk severe aortic stenosis patients underwent conventional AVR, and ...
working with flax and the flax rust fungus, defined plant–pathogen interactions genetically, producing the gene-for-gene hypothesis1. This classic concept is based on the observation that disease resistance in plants commonly requires two complementary genes: an avirulence (Avr) gene in the pathogen and a matching, resistance (R) gene in the host. The biochemical interpretation of this hypothes...
BACKGROUND The continuous suture (CS) technique has several advantages as a method for simple, fast, and secure aortic valve replacement (AVR). We used a simple CS technique without the use of a pledget for AVR and evaluated the surgical outcomes. MATERIALS AND METHODS Between October 2007 and 2012, 123 patients with aortic valve disease underwent AVR alone (n=28) or with other concomitant ca...
