Colonic Mucosa With Polypoid Hyperplasia A Pathologic and Molecular Reassessment of Endoscopically Apparent but Histologically Subtle Polyps and a Reappraisal of So-Called Goblet-Cell Rich Hyperplastic PolypsGastrointestinalHistologyMolecular diagnosticsObjectives: Define the morphologic and molecular features of ...
3). A biopsy of the colonic mass was performed, and results showed mild acute inflammatory infiltrates with hyperplastic features. A polypectomy was also performed, and the histology showed tubular adenoma with low-grade dysplasia. The patient subsequently underwent chemotherapy and radiotherapy for his...

Direct visualization of colon-associated bacteria in the colonic mucosa ACF, adjacent normal mucosa, and synchronous polyps (tubular adenomas, hyperplastic polyps (HPs), and sessile serrated adenoma polyps (SSA/P)) in Group III were directly examined for the presence of adherent bacteria using 16S ...
In rats and mice the crypts of the cecal mucosa are wider near the lumen than in the crypt base and crypts may be branched, features which may be related to the absorptive function of this zone.597 The proliferative zone in the large bowel is normally located in the lower part of the ...

Crypts were maintained in three- dimensional Matrigel culture with a simple, serum-free, low Ca2 þ (0.15 mM) medium. Intact colonic crypts from normal human mucosa were viably maintained for 3–5 days with preservation of the in situ crypt-like architecture, presenting a distinct base and ...
about the role of the different monosaccharides to determine the significance of mucins in the physiology and pathology of the bowel.In this study different carbohydrate structures have been investigated by fluorescence microscopy in normal, hyperplastic, adenomatous, and carcinomatous colonic mucosa. Lecti...
SSA/P and hyperplastic polyps have a clear endoscop- ic appearance in proximal colon which includes Mucus Cap and being isochromatic with natural mucosa with unclear edges (Figure 3). As one third of colon cancers take place through the serrated path, all colonoscopists must be able to ...
32 Low levels of MGMT methylation have also been detected in the normal-appearing colonic mucosae of individuals with MGMT-methy- lated colorectal cancers as well as individuals without neoplasia.12,30,33 This led to the suggestion that MGMT methylation may precede and predis- pose to malignant ...
