The incidence of esophageal adenocarcinoma has increased in recent years, and Barrett's esophagus is a recognized risk factor. Gastroesophageal reflux of acid and/or bile is linked to these conditions and to reflux esophagitis. Inflammatory disorders can lead to carcinogenesis through activation of "prosurvival genes," including cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS...

Polarization encoding is a promising approach for practical quantum key distribution (QKD) systems due to its simple and decoding methodology. In this study, we propose self-compensating polarization encoder (SCPE) based on phase modulator, which can be composed of commercial off-the-shelf (COT) devices. We conducted proof-of-concept experiment test the SCPE, demonstrated an in-system bit error...

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 disappe...

background: gastroesophageal reflux disease (gerd) is one of the most common gastrointestinal problems in the west while different reports indicate an increase in the prevalence in iran. the aim of this study was to estimate the preva­lence and clinical spectrum of gerd in staff of a referral hospital and evaluate the risk factors. methods: this cross-sectional study using a modified mayo clini...

Abstract Purpose Gastroretentive drug delivery systems (GRDDS) have attracted interest for enhancement of absorption and bioavailability some drugs. Itopride hydrochloride (ITOP) is a used treatment gastroesophageal reflux other gastric motility disorders, but characterized by narrow window short in vivo half-life. Therefore, it expected that its formulation expanding gastroretentive tablets wo...
