objective: alpha-synuclein is a major component of protein plaques in synucleinopathies, particularly parkinson’s disease. the purpose of this study is to assess the inhibitory effects of cuminaldehyde on the fibrillation of alpha-synuclein. methods: alpha-synuclein was expressed in escherichia coli and subsequently purified. for the process of fibrillation, purified protein was incubated at 3...
Background and Objective: Atrial fibrillation is the most prevalent arrhythmia, accompanied with some adverse complications, after coronary artery bypass graft surgery. The purpose of this study was to investigate the role of psychological risk factors, as well as age and gender for the incidence of atrial fibrillation after coronary artery bypass graft surgery. Materials and Methods: In this r...
patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. we performed an intra-operative procedure similar to surgical maze ііі procedure for conversion of this arrhythmia to sinus rhythm. we did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in pat...
patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...
mrs. heidari, 53 developed ventricular fibrillation and cardiopulmonary arrest after receiving 15 ml lidocaine 2% for local anesthesia at the dr. shariati hospital cathlab. there was no identified risk factor for her arrest preoperatively. she had a history of exertional chest pain for about 5 years and an electrocardiogram showed only inverted t-waves at the time of angiography. the case is re...
Background: The occurrence of Atrial Fibrillation (AF) is linked to an increased inflam-matory response after cardiac surgery that is significantly decreased by anti-inflammatory treatments. The present study aimed at administrating Colchicine as a way to reduce the incidence of post- Coronary Artery Bypass Graft (CABG) atrial fibrillation. Methods: In this double-blind, parallel clinical tria...
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...
background: atrial fibrillation is a common arrhythmia in patients with rheumatic mitral and other valve diseases who are candidates for valve repair surgeries. conversion of rhythm to sinus has positive effects on quality of life and lower use of medications. the aim of this clinical study was to evaluate the effectiveness of the radiofrequency ablation maze iii procedure in the treatment of a...
