BACKGROUND Many micro-RNAs (miRNAs) are differentially expressed in Helicobacter pylori-infected gastric mucosa and in gastric cancer tissue and previous reports have suggested the possibility of serum miRNAs as complementary tumour markers. The aim of the study was to investigate serum miRNAs and pepsinogen levels in individuals at high risk for gastric(More)
BACKGROUND Aspirin-induced enteropathy is now increasingly being recognized although the pathogenesis of small intestinal damage induced by aspirin is not well understood and related risk factors have not been established. AIM To investigate pharmacogenomic profile of low dose aspirin (LDA)-induced small bowel bleeding. METHODS Genome-wide analysis of(More)
Epstein-Barr virus (EBV) and cytomegalovirus (CMV) are members of the herpesvirus family and common causes of viral infection in humans. CMV infection of the gastrointestinal tract occurs mainly in immunocompromised individuals, on the other hand EBV infection and reactivation involving the gastrointestinal tract is very rare. A 56-year-old man was(More)
Background and Aim. Although many epidemiologic studies have shown that Helicobacter pylori eradication has prophylactic effects on gastric cancer, it does not completely eliminate the risk of gastric cancer. We aimed to investigate the changes in histological gastritis in patients receiving rebamipide treatment after H. pylori eradication. Methods. 206(More)
We find conditions for suppression of higher-order core modes in chalcogenide negative curvature fibers with an air core. An avoided crossing between the higher-order core modes and the fundamental modes in the tubes surrounding the core can be used to resonantly couple these modes, so that the higher-order core modes become lossy. In the parameter range of(More)
Ultrasonography is a standard, noninvasive modality used to evaluate patients with gastrointestinal diseases. This study assessed the usefulness of ultrasonography in the detection of small bowel tumors. This study enrolled 558 consecutive patients (295 males, 263 females; mean age 71.1 years) who underwent ultrasonography before capsule endoscopy and/or(More)
A direct causal relationship between a human DNA virus, adeno serotype 12, and malignant transformation in target cells (sensory retinal neuronal precursors) was suggested by the development of a remarkably uniform retinoblastoma-like neoplasm in rats. In order to focus upon incipient photoreceptor differentiation, 27 3-day-old CD rats were selected for(More)
