background: there is some evidence indicating improvement in myocardial performance after atrial septal defect closure, either device closure or surgical, but ventricular dyssynchrony has not been evaluated before and after surgical closure. the aim of this study was to evaluate ventricular mechanical dyssynchrony in patients with atrial septal defect before and after surgical closure. methods:...
The mammalian sino-atrial node is not a uniform tissue in histological and electrophysiological terms. The differences in ionic currents underlying the regional differences in electrial activity are only just beginning to be understood. One of the ionic currents it is thought to play a role in the center of sino-atrial node for action potential upstroke should be transient Ca+2 current ...
Background: Adrenergic beta antagonists are not sufficient to prevent atrial fibrillation after coronary artery bypass graft (CABG). This study was designed to evaluate the effect of ascorbic acid as an adjunct to beta-blockers in prevention of post-CABG atrial fibrillation Methods: Patients who were more than 50 years old and scheduled to undergo CABG were included if they were treated with b...
in this research with using of obtained information from a natural fraxinus the variation of quantities and qualitative measures of current stand in an 8 year period was conducted in chelir part of kheyroud forest. data collection was conducted by full callipering method in two periods of 1384 and 1392. during the period of study the parameters of dominant mean height and relative crown height ...

atrial fibrillation is the most prevalent permanent arrhythmia. it may be associated with other cardiac pathologies which need surgical treatment. various types of surgery including the traditional cut-sew operations and operations using different energy sources are currently in use. in comparison with medical treatment, surgery is safe, effective, and has reliable results.
We investigate the nature of charge transport in deoxyribonucleic acid (DNA) using self-assembled layers of DNA in large-area molecular junctions. A protocol was developed that yields dense monolayers where the DNA molecules are not standing upright, but are lying flat on the substrate. As a result the charge transport is measured not along the DNA molecules but in the transverse direction, acr...

atrial fibrillation (af) is the most common arrhythmia after cardiothoracic surgery. af following coronary artery bypass graft (cabg) is associated with an increase in morbidity, mortality, hemodynamic instability, thromboembolic events, severity of heart failure and icu and hospital stay. corticosteroids have a variety of beneficial effects on recovery after elective surgery. this study was de...
