Introduction: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. The goal of this article is to clarify an overview of the evidence linking inflammation to AF existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of AF by modulating inflammatory pathways. Mat...
Introduction: Atrial fibrillation (AF) is the most common complication of cardiac surgery which may cause remarkable morbidity and complications. Identifying predicting factors of this arrhythmia can help prophylactic therapy. The present study is designed to investigate the hypothesis that HsCRP level and P-wave characteristics are associated with the incidence of post-operative AF. Methods: ...
the effects of aflatoxin (af) (0.0 and 0.5m g kg-1) and high grade sodium bentonite (hgsb) (5, 7.5 and 10 g kg-1) were tested in an in vivo study including 8 dietary treatments with three replicates of 14 birds per diet per replicate, using a total of 336 broiler chicks up to five weeks. results showed that chicks receiving af contaminated feed had significantly (p≤ 0.05) suppressed body weight...
the purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (af) on a cross section of rat sciatic nerves. thirty adult male sprague-dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or af (n=10), (2) normal saline or ns (n=10), and (3) sham surgery (n=10). the af was aspirated from the amniotic cavity of incubat...
background: new-onset atrial fibrillation (af) after cardiac surgery contributes to increased morbidity, hospital length of stay, and resource utilization. although many aspects of af after cardiac surgery have already been elucidated, the mechanism by which cardiac surgery predisposes patients to af has hitherto remained unknown. recent evidence supports the notion that blood transfusion enhan...
در این پایان نامه ابتدا پروتکل های مخابرات مشارکتی به صورت مختصر معرفی شده و از لحاظ مرتبه ی دایورسیتی و احتمال خاموشی بایگدیگر مقایسه گشته اند. سپس نرخ خطای سمبل (ser) دو پروتکل مهم و پرکاربرد af و df، ابتدا در سیستم های مشارکتی تک رله و سپس در سیستم های مشارکتی چند رله مورد بررسی قرار گرفته و رابطه ی دقیق و تقریبی برای ser به دست آورده شده است. پروتکل معرفی شده ی df در سیتم های مشارکتی چندرله...
