UNLABELLED Xeroderma pigmentosum group G (XPG) protein plays an important role in the DNA repair process by cutting the damaged DNA at the 3' terminus. Previous studies have indicated some polymorphisms in the XPG gene are associated with stomach cancer susceptibility. We performed this hospital-based case-control study to evaluate the association of four potentially functional XPG polymorphism...

The inductive action of duodenal mesenchyme on the cytodifferentiation of stomach endoderm in chick embryos was investigated in vitro with electron microscopy and immunofluorescence. Morphologically undifferentiated endoderm of the stomach of a 4-day embryo could differentiate only into a mucous secretory epithelium when cultured in the absence of mesenchyme. However, when cultivated in recombi...

Access to the bypassed portion of the stomach after Roux-en-Y gastric bypass remains a challenge. We present a case of 64-year-old woman who presented with gastric outlet obstruction. We used a novel endoscopic technique to access the bypassed stomach by creating a jejunogastrostomy using a specialized stent, which allowed the insertion of a pediatric gastroscope to examine the bypassed portion...

PURPOSE The association between stomach cancer and colorectal cancer is controversial. The purpose of this study was to determine the synchronous prevalence of colorectal neoplasms in patients with stomach cancer. METHODS A total of 123 patients with stomach cancer (86 male) and 246 consecutive, age- and sex-matched persons without stomach cancer were analyzed from July 2005 to June 2010. All...

helicobacter pylori is a gram-negative, spiral-shaped, microaerophilic organism that colonizes the stomach of humans and causes chronic-active gastritis, peptic ulcer disease, and gastric cancers, including adenocarcinoma of the stomach and malt (mucosal-associated lymphoid tumor) lymphomas. h. pylori colonizes the stomach of over 50 % the world’s human population, primarily those who reside in...

Gastric duplications are relatively rare, and communication with the gastric lumen is extremely rare. A 67-year-old man was referred to our hospital because of recurrence of epigastric pain and fullness. An upper gastrointestinal contrast study revealed a double compartment stomach, with gastric duplication starting at the esophagogastric junction outside the greater curvature. Computed tomogra...

Estradici and progesterone receptors were assayed in tumors from 79 patients with primary colorectal and 56 patients with stomach adenocarcinomas. Eighteen of 79 colorectal cancers contained estradiol receptor, while 34 specimens were positive for progesterone receptor. In stomach cancer, the positive sam ples were 8 for estradiol and 14 for progesterone receptors. In both types of tumors, the ...

We report the rare case of an elderly patient with an advanced gastric cancer arising from an upside-down stomach through a paraesophageal hiatal hernia (PEH). An 82-year-old man presented with appetite loss and anemia. Upper gastrointestinal endoscopy revealed a type 1 tumor located in the middle body of the stomach. An upper gastrointestinal series and computed tomography showed organoaxial r...

h. pylori  is a human pathogen that colonizes the epithelium of the stomach. the host immune response may influence the disease process, where cytokines play important roles in the development of disease. in this study, the concentrations of selected cytokines in the gastric antrum and stomach body mucosa and also in the serum were evaluated. eighty patients according to their rapid urease test...

The relation between gastric emptying and the intragastric distribution of300 ml radiolabelied beef consomme with and without 60 g margarine was investigated by performing randomised, paired gammacamera studies in seven healthy male volunteers (aged 20-22 years). The low calorie bland meal emptied rapidly from both the proximal and distal stomach after a short lag period (4-6 min), during which...
