Open Access Obscure gastrointestinal bleeding (OGIB) is defined as overt or obscure gastrointestinal bleeding of unknown origin despite an initial endoscopic evaluation including colonoscopy and esophagogastroduodenoscopy. The majority of patients with OGIB have a bleeding source in the small intestine. In past decades, the evaluation of the small bowel was extremely limited because of difficul...

Bile leaks after laparoscopic cholecystectomy are usually treated using endoscopic retrograde cholangiopancreatography (ERCP). The presence of complex, surgically altered gastrointestinal anatomy poses a diagnostic and therapeutic challenge to the endoscopic treatment of these lesions. Herein, we present a patient with Roux-en-Y gastric bypass who developed a bile leak after cholecystectomy and...

AbstractStringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for the petro-diesel. The oxygenated fuel used is dibutyl ether(DBE). While injection pressure is 200 bar and injection timing is 20.5 0 BTDC we get higher brake thermal efficiency and lower brake specific fuel consumption for DBE10 compare to diesel.

Objectives Transabdominal ultrasonography (US) has been reported as a useful tool for evaluating Crohn's disease (CD) activity. Endoscopic findings and activity index (CDAI) are currently considered the gold standard assessing CD We assessed correlation between US double-balloon endoscopy (DBE), CDAI Methods analyzed patients with undergoing DBE within 10 days procedures. The intestine was divi...

Haloalkane dehalogenase (DhlA) catalyzes the hydrolysis of haloalkanes via an alkyl-enzyme intermediate. Trp175 forms a halogen/halide-binding site in the active-site cavity together with Trp125. To get more insight in the role of Trp175 in DhlA, we mutated residue 175 and explored the kinetics and X-ray structure of the Trp175Tyr enzyme. The mutagenesis study indicated that an aromatic residue...

Expression of the pulmonary surfactant protein A (SP-A) gene is lung specific, developmentally regulated, and enhanced by hormones and factors that increase cAMP. We previously identified two E-box-like enhancers termed distal binding element (DBE) and proximal binding element (PBE) in the 5'-flanking region of the rabbit (r) SP-A gene that are essential for cAMP induction of rSP-A promoter act...

South Africa has high rates of HIV infection among its young population, unintended pregnancy the youth, and extremely gender-based violence. Given all this, it is essential that people be taught skills will enable them to manage their sexuality. Schools have been shown best placed provide accurate relevant information on people's sexualities. Through Life Orientation (LO) curriculum, Departmen...
