A 70-year-old woman visited our hospital complaining of anemia. Laboratory testing revealed a peripheral blood hemoglobin concentration of 9.4g/dL. Upper and lower gastrointestinal endoscopic examinations were performed to investigate the cause of the anemia. The findings of the upper endoscopic examination were normal. However, the lower endoscopic examination revealed a semipedunculated polyp...

single filiform polyp discovered during routine screening in an individual without symptoms or a history of colonic disease. A 47−year−old man was transferred to our outpatient department for treatment of a single colon polyp which had been inci− dentally found on medical examination. Other results including upper endoscopy and laboratory test except colonoscopy were normal. The patient was asy...

PURPOSE To assess the diagnostic performance of distributed human intelligence for the classification of polyp candidates identified with computer-aided detection (CAD) for computed tomographic (CT) colonography. MATERIALS AND METHODS This study was approved by the institutional Office of Human Subjects Research. The requirement for informed consent was waived for this HIPAA-compliant study. ...

Adult intussusception is clinically rare. We report a case with colon intussusception caused by a pedunculated polyp of the sigmoid colon in a 54-year-old male. Abdominal ultrasonographic screening for hematochezia showed intussusception in the sigmoid colon, demonstrating a multiple concentric ring sign and a mobile leading colon polyp. Histological examination of a biopsy specimen of the poly...

Abstract Aims The Joint Advisory Group on GI Endoscopy (JAG) has set key quality indicators for colonoscopy, which includes an adenoma detection rate of a minimum 15%. Given the difficulty in reporting rate, JAG have stated that polyp is accepted as surrogate measure. Our aim was to assess whether can be used substitute marker detection, by examining histology samples taken polyps determine wha...

A66-year-old Koreanmanwas referred for colonic polypectomy. A colonoscopy performed at another hospital 1 week previously had revealed a large pedunculated polyp with an erythematous surface that was occupying almost the entire lumen in the mid-sigmoid colon (●" Fig.1). The polyp appeared hyperplastic, and no biopsywas performed. The patient was not taking any nonsteroidal anti-inflammatory dru...

Thermophilic mannanase from the Bacillus sp. MG-33 was applied on wheat straw-rich-soda pulp to evaluate its bleaching potential. Optimum conditions for bio-bleaching of pulp were found as, mannanase 3Ug -1 of pulp at pH 6.5 and temperature 65oC that enhanced the brightness by 30% and reduced the kappa number by 20% within 2h. Tear index (1.1, points) and burst index (0.02, points) were also im...

aim :  the aim of this study was to present the demographic and clinical characteristics of patients with gastric polypoid lesions and to study the histopathologic features of these lesions. background : the frequency of gastric polyps is gradually increasing due to the widespread use of endoscopic examinations. patients and methods : clinical and endoscopic features of 100 gastric polyposis pa...

We report the isolation and expression of the Hox gene, Cnox-2, in Hydractinia symbiolongicarpus, a hydrozoan displaying division of labor. We found different patterns of aboral-to-oral Cnox-2 expression among polyp polymorphs, and we show that experimental conversion of one polyp type to another is accompanied by concordant alteration in Cnox-2 expression. Our results are consistent with the s...
