Introduction: The arteriovenous (AV) fistula is a gold standard method for safe and effective repeated vascular access for patients on hemodialysis (HD). The patients, with AV-fistula access in their upper limb, have some limitations in using the involved limb both in daily living and during the dialysis process. The aim of this study was to compare range of motion (ROM), muscle strength and...
Introduction: Endorphins are produced by cardiomyocytes, and exert different effects on the heart. The aim of the present study is to assess morphine effects on extracellular atrioventricular (AV) node field potential pattern and ventricular rhythm of isolated rabbit heart during experimental atrial fibrillation (AF). Methods: Effects of different concentrations of morphine (10, 20, 50 and 1...
Introduction: Intranodal pathways of atrioventricular (AV) node play a vital role in the delay of conduction time in response to various atrial inputs. The present study was aimed to determine the frequency-dependent electrophysiological properties of concealed slow pathway according to a functional model of isolated rabbit atrioventricular node preparation after fast pathway ablation. Meth...
OBJECTIVE To compare the mid-term results after aortic valve (AV) repair in bicuspid AVs with those in tricuspid AVs. METHODS Between 2000 and 2010, 100 patients (mean age 47.2 years) underwent AV repair procedures for insufficient bicuspid AV (n=43) and tricuspid AV (n=57). Aortic regurgitation (AR) more than moderate was present in 31/43 and 21/57 patients in the bicuspid AV and the tricusp...
زمینه و هدف: روش های مختلفی برای طولانی تر شدن بلوک شبکه آگزیلاری در اعمال جراحی اندام فوقانی معرفی شده است. در این مطالعه سعی شده است تأثیر دگزامتازون در ترکیب با لیدوکایین در بلوک شبکه آگزیلاری مورد بررسی قرار گیرد.روش بررسی: مطالعه حاضر به صورت یک کارآزمایی بالینی تصادفی شده دو سوکور طراحی و اجرا شد. بیماران کاندید عمل جراحی اندام فوقانی که در اتاق عمل اورژانس بیمارستان حضرت فاطمه (س) بستری ...
OBJECTIVE The effects of Lactobacillus rhamnosus GG (LGG) and Aloe vera (AV) gel on lipid profiles in rats with induced hypercholesterolemia were studied. METHODS Five treatment groups of rats (n = 7) were the fed experimental diets: a normal control diet, a hypercholesterolemic diet (HD), HD + LGG, HD + AV gel, and HD + LGG + AV gel. RESULTS Supplementation with LGG decreased serum total c...
Talker localization is indispensable in video conferencing. Statistical audio-visual (AV) talker localizers that fuse AV features based on prior statistical property are ideals. However, statistical property must be estimated prior to the AV feature fusion procedure. To overcome this problem, this paper proposes a novel robust and omnidirectional AV talker localizer that dynamically fuses AV fe...
AV-node modification by catheter RF energy delivery is treatment of choice in the symptomatic patients with AVNRT. This study included 30 patients with AVNRT (19 women, 11 men). We did slow pathway ablation in 29 cases successfully. Maximum effective energy delivery was 40 watts for 40 msec. 1:1 AV conduction increased from 290±40 msec before ablation to 340±65 msec after ablation. Also AV-node...
In this study, a single-step method for green synthesis of silver nanoparticles usingAloe Vera gel extract and sunlight was investigated. The Aloe Vera gel extractis composed of pectins, lignin, and hemicellulose, which can be used in thereduction of silver ions to produce colloidal silver nanoparticles (AgNPs-AV). Thepreliminary preparation of silver nanoparticles was o...
The digitization of library documents and archives increasingly extends to audiovisual (AV) document repositories. As a consequence, new computer-aided techniques are being devised, providing opportunities for new uses of AV documents. As scholars work mainly by reading, annotating, reusing, and producing documents they are directly concerned by these changes. The rst part of this article descr...
