Background: The leaf extract of Croton zambesicus (CZ) is used in traditional medicine for the management of various conditions including kidney disease. The purpose of this study was to determine the protective effects of leaf extract of CZ on rat kidney toxicity induced by carbon tetrachloride. Method: Male albino rats were divided into 6 groups of 5 rats and treated for 5 days with aqueous ...

Objective: To investigate the anti ulcer effect of aqueous extract of Azolla filiculoides (AF) in experimentally induced gastric ulceration in male Wistar rats. Methods: Twenty four rats were divided into four groups of six rats in each group. The group I and III rats were fed with standard diet, whereas, group II and IV rats were pre-treated orally with aqueous extract of Azolla filiculoides (...

Teucrium polium (Labiatae) is a plant that widely grows in Iran. Some of species of Teucrium are used for a considerable range of actions in traditional medicine and T. polium has frequently been used as anticonvulsant. In this study, we investigated the protective effects of T. polium ethanolic aqueous extracts and related fractions on seizures induced by pentylenetetrazole (PTZ) and maximal e...

Objectives Detection of the echocardiographic predictors of post-operative atrial fibrillation in patients with rheumatic mitral valve disease undergoing mitral valve replacement. Methods The study included 50 patients with rheumatic mitral valve disease undergoing mitral valve replacement. Preoperative assessment included standard two-dimensional echocardiography to assess LA diameter, volum...

BACKGROUND Catheter ablation for atrial fibrillation is a clinically established treatment by now while success rate varies between 60% and 85%. Interventional treatment of atrial fibrillation is still a challenging technique associated with a long procedure time and risk of major complications in up to 6 % of treated patients. The aim of this study was to investigate the predictive value of pl...

BACKGROUND Several studies have examined the link between atrial fibrillation (AF) and various echocardiographic measures of cardiac structure and function in whites and other racial groups but not in blacks. Exploring AF risk factors in blacks is important given that the lower incidence of AF in this racial group despite higher risk factors, is not completely explained. METHODS We examined t...

BACKGROUND Left atrial remodeling caused by persistent atrial fibrillation (AF) causes atrial functional mitral regurgitation (MR), even though left ventricular (LV) remodeling and organic changes of the mitral leaflets are lacking. The detailed mechanism of atrial functional MR has not been fully investigated. METHODSANDRESULTS Of 1,167 patients with AF who underwent 3D transesophageal echoc...

S troke is a devastating complication of atrial fibrillation (AF), causing substantially greater neurological deficit than strokes in non-AF patients, as well as longer hospital admission, higher rates of death, and reduced ability to function independently. The risk of stroke in AF is not homogeneous and is closely associated with common patient characteristics, as summarized by the CHA 2 DS 2...

BACKGROUND Three dimensional echocardiography (3DE) approaches the accuracy of cardiac magnetic resonance in measuring left ventricular (LV) volumes and ejection fraction (EF). The multibeat modality in comparison to single-beat (SB) requires breath-hold technique and regular heart rhythm which could limit the use of this technique in patients with atrial fibrillation (AF) due to stitching arti...

We present La NMR experiments on five powder samples of lanthanum manganites, with a Mn concentration ranging from the antiferromagneticinsulator (AF) to the ferromagnetic-conducting (FM) region of the phase diagram. We measure a positive hyperfine coupling C=0.13 T/μB. A signal from nuclei in a FM environment is present at all compositions, as evidenced by a hyperfine frequency in zero field e...
