in 32.1% of chronic diarrhea patients with normal colonoscopy, which can justify, in certain cases, mucosa biopsies, which might contribute for a more precise etiologic diagnosis; also, the distribution of these histologic changes has pointed out the importance of having all colon segments biopsied....
The distribution of intermediate - sized filaments in human colon mucosa as well as in adenomas and carcinomas of the colon was studied by means of both immunohistology and electron microscopy. The epithelial cells of the colonic mucosa are definitely labelled with antibodies against prekeratin (cyt...
The Proteolytic Activity in Normal Mucosa and in Adenocarcinomas of the Colon and Rectum. A Study on 49 Patients 来自 ResearchGate 喜欢 0 阅读量: 14 作者:NP Aardal,J Solsvik,KJ Andersen 会议名称: XX International Congress of the International Academy of Pathology ...
Fresh biopsies from one patient with MUTYH-associated familial adenomatous polyposis were obtained by colonoscopy. Tissues (approximately 0.5 × 0.5 × 0.5 cm3in size) were cut from four polyps. Matched blood and buccal mucosa tissue from the same patient were also collected. All t...
Endoscopy disclosed acute gastric mucosal lesions including mucosal edema, erosions, and ulcers with blood crusts in the antrum. Touch cytology and histological assessment obtained from the affected mucosa revealed acute neutrophilic gastritis and single longer and more coiled organisms than Helicobacter ...
Low-level methylation was detected by quantitative methylation-specific PCR in the normal colonic mucosa of cases, particularly those with a correspondingly methylated tumour, as well as controls without neoplasia, and this was also associated with the C4T SNP. We show that the T allele at SNP ...
After absorption, the reactivity of the sera with normal colon mucosa and carcinomas of the colon remained positive, whereas sections of benign tissues were negative. Moreover, four of ten breast cancers, positive with unabsorbed antisera, became negative after absorption. These findings stress the ...
We conducted a genome-wide DNA methylation study on samples of normal colon mucosa (N = 334). Subjects were assigned to three cancer risk groups (low, medium, and high) based on their personal adenoma or cancer history. Using previously established epigenetic clocks (Hannum, Horvath, PhenoAge...
In this manner, they can be passed through the channel of a gastroscope or colonoscope. Some biopsy forceps have a spike at the base of the cup or teeth to help seat the forceps against the mucosa. The spike also helps to impale multiple biopsy specimens before the forceps is remov...
The tumour was localised in the right hemicolon in 36% of the patients, 42% had left-sided cancer and in 22% the tumour was localised in the rectum. In 42% of the patients, the tumour was smaller than 5 cm in diameter and in 23% there was a mucinous component in the histology. ...
