OBJECTIVE Diabetes mellitus is recognized as a risk factor for mortality and morbidity after coronary bypass grafting. We aimed to determine the association between preoperative hemoglobin HbA1c and AF after isolated off-pump coronary bypass grafting (OPCAB). METHODS The seventy-two diabetic patients undergoing isolated off-pump coronary bypass grafting were retrospectively analyzed for AF. T...

introduction tectonic of binaloud mountain ranges is controled by thrust faults system and folds related to these faults. parts of this mountain ranges and neyshabour plain is as study area in north eastern iran and between latitudes 36° 11´ 00 to 36° 30´ 00 and longitudes 58° 35´ 00 to 59° 00´ 00. in this paper we first study morphometric indices in this area then analyze drainages and allovia...

The Kordkanlo Basin, one of the Atrak sub-basins, located in the northeastern of the Ghoochan city, the Khorasan Razavi Province; is situated in Kopet Dagh geologic zone. The overall objective of this study is to evaluate the morphotectonic effects on the drainage network of the basin, using morphometric indicators. In this research, morphometric quantitative indicators of hypsometric integral ...

Blevins’s Evolutionary Phonology attempts to derive most if not all synchronic phonological patterns from diachronic changes: “[R]ecurrent synchronic sound patterns are a direct reflection of their diachronic origins, and, more specifically...regular phonetically based sound change is the common source of recurrent sound patterns. Evolutionary Phonology...investigates this hypothesis and explor...

in this study, the quaternary deformation and tectonic activity of saeedabad-chai drainage basin, are assessed using geomorphic approach. this drainage basin is located in northern slope of sahand mountain. north tabriz fault (ntf), is passing from the saeedabad-chai basin. variation in the morphology of mountain front provied the basis for geomorphic assessment of tectonic activity. therefore,...

study of tectonic affects in many fluvial systems shows that, rivers are valuable tools to active tectonics surveying. study of stream channels and their associated deposits offset by faulting may reveal the amount displacement at particular site and give information that is critical for future earthquake hazards evaluation. study area which is a subbasin of atrak river is located at the ne ira...

OBJECTIVES Mediastinal drainage following cardiac surgery with traditional large-bore plastic tubes can be painful and cumbersome. This study was designed to determine whether prolonged drainage (5 days) with a silastic tube decreased the incidence of significant pericardial effusion and tamponade following aortic or valvular surgery. METHODS One hundred and fifty patients undergoing valvular...

I read with interest the paper by Singh and coworkers on the subject of pleural drainage [1]. In the respiratory field, this is a hot topic and guidelines were recently published [2]. Singh and coworkers used a 16-French gauge catheter, which is broadly in agreement with the British Thoracic Society guidelines (and this is what we sometimes use in our hospital). However, the British Thoracic So...
