Does helicobacter pylori induce up-regulation of the epidermal growth factor receptor in AGS gastric epithelial cells?
Infection of gastric epithelial cells by H. pylori triggers an autocrine loop whereby EGFR transactivation leads to the up-regulation of EGFR expression. This, in turn, may contribute to unrestrained epithelial cell proliferation and carcinogenesis.
This study indicates that a calculated volume of intravenous fluid administered during bowel preparation improves patient outcomes with respect to blood transfusion and postoperative oliguria. We advocate calculated intravenous fluid administration in all patients undergoing bowel preparation prior to colonic surgery.
