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...
This study was designed to develop and test a system to monitor adherence with nonhormonal oral chemotherapeutic agents using an automated voice response (AVR) system plus nursing intervention. Participants were patients diagnosed with solid tumor cancers, primarily breast, colon, and lung cancers, who received the Symptom Management Toolkit and participated in an interview for symptom severity...
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...
PURPOSE To explore the association between axial length and retinal vascular network geometry (arteriovenous diameter ratio [AVR], arteriolar branching angles, and junctional exponents). DESIGN Prospective, cross-sectional study. METHODS Patients were recruited from a pseudophakic population that had preexisting axial length measurements. Mean arterial blood pressure and previous medical hi...
Aortic stenosis is the most common valvular heart disease in the Western world. It is caused primarily by age-related degeneration and progressive calcification typically detected in patients 65 years and older. In patients presenting with symptoms of heart failure, the average survival rate is only 2 years without appropriate treatment. Approximately one half of all patients die within the fir...
