The gastrointestinal tract is responsible for the entire digestive process. Several diseases, including colorectal cancer, can affect this pathway. Among deadliest cancers, cancer second most common. It arises from benign tumors in colon, rectum, and anus. These tumors, known as polyps, be diagnosed removed during colonoscopy. Early detection essential to reduce risk of cancer. However, approxi...

We have developed a method for the routine primary culture of human colonie epithelial cells. Cultured cells exhibited char acteristic epithelial structures, including a brush border and junctional complexes. Flask-like goblet cells containing mucus were also seen within the epithelial monolayer. [3H]Thymidine labeling indices were used to distinguish between cultured cells from familial polypo...

Ann Saudi Med 28(3) May-June 2008 www.saudiannals.net 217 Fibrovascular polyps are extremely rare benign neoplasms of the hypopharynx that can arise from any site in the pharynx.1,2 Because of the mixture of stromal tissues, it is hypothesized that the fibrovascular polyp may be a hamartoma or an unusual type of inflammatory polyp. Another theory is that they arise secondary to mucosal injury,3...

ity of nonfundic gland gastric polyps found incidentally at endoscopy [1]. Ma− lignant transformation has been reported in hyperplastic polyps but invasive carci− noma is rare [2]. A 63−year−old female was referred for routine screening colonoscopy and eso− phagogastroduodenoscopy because of pernicious anemia diagnosed 10 years previously. Upper gastrointestinal endos− copy revealed a 3 cm beni...

A method employing sphere fitting and graph-based clustering is presented to determine possible locations of polyps in a CT colon image dataset. The method is conservative in that it misses essentially no polyp greater than a specified minimum size, at the cost of several false positives. The output from the algorithm is sufficiently small that more sophisticated classification methods can be s...

Computer aided detection (CAD) systems have emerged as noninvasive and effective tools, using 3D CT Colonography (CTC) for early detection of colonic polyps. In this paper, we propose a robust and automatic polyp prone-supine view matching method, to facilitate the regular CTC workflow where radiologists need to manually match the CAD findings in prone and supine CT scans for validation. Apart ...

Abstract An endometrial polyp is most commonly a benign, localized proliferation of the glands and stroma, covered with epithelium protruding above level mucosa. These polyps are often diagnosed during investigation into causes irregular menstrual bleeding or infertility. It produced in highest concentration secretory phase cycle. The glycodelin reaches its peak 12 days after ovulation. aim thi...

COX-2 overexpression is widely recognized as an accidental and relatively important factor in the progress of colon neoplasia, but the practical significance of it has not yet been defined. As such, the purposes of the study were: an analysis of the changes of COX-2 expression within colon adenomas in the dependence of progress of dysplastic level within colon adenomas, the analysis of COX-2 ex...
