Gastrointestinal infection due to cytomegalovirus occurs frequently in liver transplant recipients. Upper gastrointestinal cytomegalovirus infection is associated with subjective complaints of nausea, a sense of abdominal fullness, and occasionally emesis and/or dysphagia. In order to determine whether these symptoms reflect a disruption of the normal motility of the stomach, the following stud...
Massive upper gastrointestinal bleeding is a life-threatening emergency which needs urgent intervention. Hematological malignancies are very rare causes of this type of bleeding and they usually originate from duodenum. In this case we present a gastric diffuse large B-cell lymphoma (DLBCL) causing massive upper gastrointestinal system bleeding. A 77-year-old male patient was admitted to emerge...
PURPOSE To optimize radiolabeling with (99m)Tc of mannosylated Gantrez(®) nanoparticles loaded with the Brucella Ovis antigen (Man-NP-HS) and to carry out biodistribution studies in mice after ocular administration of the nanoparticles. MATERIAL AND METHODS Man-NP-HS nanoparticles were prepared by the solvent displacement method. They were purified, lyophilized and characterized. Following th...
An 82-year-old Japanese man presented with a gastric involvement of peripheral T-cell lymphoma, not otherwise specified. Although gastrointestinal lesions were not detected on computed tomography, oesophagogastroduodenoscopy revealed a slight elevation of the gastric mucosa, with changes in mucosal colour and the presence of abnormal microvessels. This led to the prompt detection of gastric inv...
Establishment of mucosal and/or luminal colonization is the first step in the pathogenesis of many gastrointestinal bacterial pathogens. The pathogen must be able to establish itself in the face of competition from the complex microbial community that is already in place. We used culture-independent methods to monitor the colonization of the cecal mucosa of Helicobacter-free mice following expe...
Clinical significance of erosive gastritis in patients with alcoholic liver disease and upper gastrointestinal hemorrhage. (1982). Results of surgical management of hemorrhagic gastritis in patients with gastroesophaageal varices.rrhagic gastritis in a patient with portal hypertension and esophagogastric varices: The role of portal decom-pressive surgery. Am. Distorted microangioarchitecture an...
Four selenocysteine-containing proteins (gastrointestinal glutathione peroxidase, plasma glutathione peroxidase, selenoprotein P, and thioredoxin reductase-alpha) are expressed in the colonic mucosa. Because of their antioxidant functions, a protective role in colon carcinogenesis is discussed. The aim of this study was to elucidate an involvement of gastrointestinal selenoproteins during the a...
BACKGROUND Functional dyspepsia (FD) is a heterogeneous disorder associated with diverse pathophysiological mechanisms, including immune activation and low-grade mucosal inflammation. Genetic factors, physiological functions, and environmental factors may determine the relative importance of various pathophysiological mechanisms. This study was designed to determine the histological alterations...
