Introduction: Recent studies showed that nitrergic system have specific modulatory effects on electrophysiological properties of atrioventricular (AV) node. The aim of this study was to determine the effects of nitric oxide (NO) on the electrophysiological properties of isolated rabbit AV node and to investigate the role of adrenergic and cholinergic receptors in the mechanism of its action...

This paper compares three net art projects combining sound and animation by the author and André Carrilho (under the name Video Jack): AVOL, Master and Margarita and AV Clash. They follow a development path aiming to create projects enabling integrated audiovisual creativity that are flexible, intuitive, playful to use and engaging to experience. The comparative evaluation of the projects focus...

Background and Objectives: There are different types of vascular access. We compared the patency rate for six months in ulnar-basilic fistula and Radio-Cephalic fistula for vascular access in hemodialysis patients.   Methods: The study was performed on 60 patients of 50.6±13.5 years of age with end-stage renal failure undergoing hemodialysis from 2012-2014 in Imam Ali hospital in Zahedan. Pat...

crohn's disease is a type of chronic inflammatory bowel disease (ibd) of unknown etiology that may affect any part of the gastrointestinal tract from mouth to anus and shows extra-intestinal involvement. it characteristically shows skip lesions. this case report reported in 2014 describes a middle age pakistani male known to have documented evidence of significant crohn's disease since past 18 ...

Background & Objective: To find an association between gene variants of insulin-like growth factor-1 (IGF-1) and 5,10-methylenetetrahydrofolate reductase (MTHFR) with the risk of acne vulgaris (AV). Methods: In a case-control study, we investigated 150 AV patients and 148 healthy individuals (aged 18-25 years) for the IGF-1 G>A and MTHFR C677T polymorphis...

In population-based studies, up to 50% of patients with Crohn's disease suffer from fistulas. Fistulas pose a considerable morbidity including permanent sphincter and perineal tissue destruction as well as professional and personal disabilities. Treatment options have progressed in recent years and fistula closure and fibrosis of the fistula track is achieved in some patients. Depending on seve...

INTRODUCTION. Arteriovenous fistulas and grafts are two common permanent access methods for hemodialysis. Selection of an appropriate access, appropriate surgical techniques, and treatment of complications are basic principles of long-term maintenance of vascular access. We aimed to assess the survival of arteriovenous fistulas and grafts in our dialysis center. MATERIALS AND METHODS. A total o...
