Helicobacter pylori infection leads to gastroduodenal inflammation, peptic ulceration and gastric carcinoma. Proteomic analysis of the human gastric mucosa from the patients with erosive gastritis, peptic ulcer or gastric cancer, which were either infected or not with H. pylori, was used to determine the differentially expressed proteins by H. pylori in the human gastric mucosa in order to inve...
BACKGROUND Helicobacter pylori-induced gastritis is an important factor for gastric carcinogenesis. However, it is still controversial whether it is also applicable for cardiac cancer development. Recently, we reported that H. pylori is an important factor for the induction of cardiac inflammation. We examined the status of H. pylori-induced gastritis in patients with cardiac cancer. METHODS ...
BACKGROUND Spontaneous gastric perforation is a rare clinical disorder. The majority of the available data have been reported in the neonatal age group. There are a few cases of spontaneous gastric perforation in preschool children. To our knowledge, there is no published information on spontaneous gastric perforation in older children and adolescents. CASE REPORT We describe the presentation a...
Gastric epithelium is protected by a mucus layer rich in MUC5AC and MUC6 mucins synthesised by the superficial epithelium and the glands, respectively. These cell populations also express specific fucosyltransferases that determine the glycosylation pattern of these gastric mucins. The maintenance of the structure and properties of the gastric mucus has been related to the degree of glycosylati...
The oxygen-derived free radicals that are released from activated neutrophils are one of the cytotoxic factors of Helicobacter pylori-induced gastric mucosal injury. Increased cytidine deaminase activity in H. pylori-infected gastric tissues promotes the accumulation of various mutations and might promote gastric carcinogenesis. Cytotoxin-associated gene A (CagA) is delivered into gastric epith...
BACKGROUND AND AIM Some patients with eosinophilic esophagitis (EE) (>15 eosinophils/high-power field on esophageal mucosal biopsies and lack of response to acid suppression and/or normal pH probe study) demonstrate incidental eosinophilic inflammation of the gastric mucosa. It is unclear whether patients with EE and normal gastric biopsies (EE-N) are phenotypically different from patients with...
CD24 is expressed in the putative stem cells within several tissues and is overexpressed in gastric and colonic adenocarcinomas. Perturbed CD24 expression may therefore alter the response of gastrointestinal epithelia to damage-inducing stimuli that induce cancer. We have investigated the effects of CD24 deletion on gastric responses to Helicobacter felis infection and γ-irradiation using CD24-...
Acute respiratory distress syndrome (ARDS) is a life-threatening lung injury characterized by rapid onset of widespread inflammation in the lungs. Multiple risk factors, including pneumonia, non-pulmonary sepsis, aspiration gastric contents or inhalation injury, have been reported, to cause ARDS. We present case healthy young woman her first trimester with vaping-induced who presented spontaneo...
Helicobacter pylori associated duodenal ulcers occur in patches of gastric metaplasia. The pathogenesis of gastric metaplasia is unclear, but it has been produced in experimental animals by acute injury and has been shown to be present to a greater extent of H pylori positive subjects. This study aimed to discover if gastric metaplasia regressed with eradication of H pylori or healing of duoden...
Bile reflux gastritis is due to an excessive reflux of duodenal contents into the stomach. The increased enterogastric reflux may provide the basis for increased mucosal injury. Bile reflux gastritis can appear in two circumstances: gastric resection with ablation of pylorus and primary biliary reflux due to the failure of pylorus. The aim of the study was to evaluate the endoscopical and histo...
