introduction and aims: both observational and experimental studies have shown that higher selenium status reduces the risk of upper gastrointestinal cancers in selenium deficient populations. recent cancer registry data have shown very different rates of esophageal cancer (ec) and gastric cancer (gc) in four provinces of iran, namely ardabil, mazandaran, golestan, and kerman. the aim of this st...

introduction: recently, hydrogen sulfide has been introduced as the third gas that acts as a transmitter. it has many physiological and pharmacological roles in the human body. the aim of the present study was to investigate the effect of exogenously administered and endogenously produced h2s on the basal and distention-induced gastric acid secretion in rats. methods: forty-nine male wistar rat...

introduction: the objective of the present study is to investigate the relationship between the familial history of digestive system cancers and development of gastric cancer. methods: in this case-control study conducted in 2012, 84 patients with a definite diagnosis of gastric cancer, diagnosed using endoscopy and pathological study of biopsies, were compared with 84 people with the same age ...

it has been shown that enhanced acid secretion can be suppressed in the rat by systemic administration of glucose. we have recently reported that enhancement of acid secretion as a result of pentagastrin was diminished by intragastric administration of d-glucose. present study was designed to investigate whether intragastric d-glucose influences gastric acid secretion associated with carbachol ...

background : gastric cancer is a common and lethal disease throughout the world. in iran with 7300 new cases annually, it is the first cause of cancer related death in both sexes. regarding the high incidence (10.5/100000 individuals) of gastric can­cer and priority of prevalence index in cancer management, in this study we tried to determine 1, 2-3 and 4-5 year point preva­lence of the disease...

objective(s): expression of her2 in gastric carcinoma has direct prognostic and therapeutic implications in patient management. the aim of this study is to determine whether a relationship exists between standardized uptake value (suv) and expression of her2 in advanced gastric carcinoma. methods: we analyzed the 18f-fdg pet/ct results of 109 patients that underwent gastrectomy for advanced gas...

introduction the popularity of sleeve gastrectomy, as a treatment for morbid obesity, has increased recently due to its safety and relatively technical simplicity. sleeve gastrectomy, however, is not free of complications and due to the increased number of cases performed with this method, new postoperative complications would be expected to be experienced. few cases of gastric volvulus are rep...
