AIM To review the literature concerning gastro-oesophageal reflux during the sleep period, with particular reference to the sleep/awake state at reflux onset. METHODS Studies identified by systematic literature searches were assessed. RESULTS Overall patterns of reflux during...
production ofdimethyl amino ethanol (dmae) and effective parameters on efficiency and purity of the chemical were studied in this article. dimethylation of ethanol amine using aqueous formaldehyde in the presence of formic acid was applied for production of dmae. results showed that four parameters such as outlet temperature of co2 gas, reflux temperature, reflux time and extraction solvent wer...
Background & Aim: Varicocele is the dilation of the pampiniform venous plexus of testis more than 2 mm and is one of the most common causes of sperm abnormalities in infertile men. The main diagnostic test for varicocele is ultrasonography that evaluates the vein diameter in B mode exam and venous reflux in color Doppler exam, but there is no single agreement on the importance of these two ...

Classic anti reflux procedures on children with a history of posterior urethral valve does not usually yield good results and often ends up with ureteral obstruction and even permanent urinary diversion. From 1981 through 1988,21 boys with history of posterior urethral valve (PUV) underwent evaluation for vesicoureteral (VU) reflux 17 boys had VU reflux. Following valve ablation, reflux di...
We examined the relationship between microscopic hematuria and inferior vena cava (IVC) reflux. Transabdominal color Doppler ultrasonography of the IVC was performed in the supine position with the convex probe positioned perpendicular to the upper abdominal wall, and the extent of reflux into the IVC with each heart beat was examined near the diaphragm. A total of 171 patients were studied who...
