OBJECTIVE To evaluate the feasibility and long-term results of early gastric surgery for patients with isolated gastric stricture following acid corrosion injury. MATERIALS AND METHODS Upper gastrointestinal (UGI) series was routinely performed around the 4th week after acid corrosion injury. Patients with gastric stricture and no risk of delayed esophageal stricture underwent early solitary ...

aim : the present study aimed to evaluate the prevalence of positive family history of these cancers in a large population-based sample of tehran province, capital of iran. background : upper gastrointestinal (ugi) cancers (gastric and esophagus cancer) constitute a major health problem worldwide. a family history of cancer can increase the risk for developing cancer and recognized as one of th...

The synthesis of multivalent neoglycoconjugates with 2,6-diamino-2,6-dideoxyglucose is accomplished by a flexible Ugi multicomponent approach leading to mono-, di- and tri-valent carbohydrate clusters.

A post-Ugi indium(III)- and gold(I)-mediated regioselective intramolecular hydroarylation for the synthesis of azepino- and azocino-[c,d]indolones is described.

Easily prepared nanoZnO was found to be as an efficient catalyst in the synthesis of 1,4-DHPs via four-component reaction of 1,3-dicarbonyls, aldehydes and ammonium carbonate in water at 60 °C. The prepared nanoZnO was characterized by XRD and FT-IR analysis, while the determined specific surface area of nano catalyst by BET method was 33 m2/g.

BACKGROUND Diagnostic upper gastrointestinal (UGI) endoscopy has been regarded as a safe procedure. CASE REPORT We report of a 67-year-old woman who developed epigastric pain and dyspeptic complaints following an uneventful upper gastrointestinal endoscopy. The diagnosis of an acute reversible duodenitis was made on the basis of imaging studies. A duodenal diverticulum was also found on CT im...
