Although the main function of the stem cells is to maintain the cell populations of the colonic tubular glands during normal wear and tear and cell turnover, they are also vital in the rapid replacement of cells damaged by disease. When only the epithelial cells of the colonic tubular glands...
ITAC into five categories: tumours resembling colonic subtype (40%), tumours with solid architecture (20%), papillary tumours (18%), tumours resembling colonic mucinous or colloid carcinoma which can show focal signet ring cells (14%), and mixed type with combinations of these subtypes (8%)....
Fiber in the diet both softens the stool and increases the power of colonic contractions, optimizing the activities of the colon. Chemical Digestion Although the glands of the large intestine secrete mucus, they do not secrete digestive enzymes. Therefore, chemical digestion in the large intestine ...
1. To evaluate the effect of age, sex and level of intake on the colonic response to wheat fibre, thirty healthy volunteers aged 17–62 years (nineteen men, eleven women) recruited from a local industry, were divided into four groups and given a controlled diet for two 3-week periods. ...
amounts of vitamins by fermentation. Vitamin K and B vitamins, including biotin, are produced by the colonic bacteria. These vitamins are then absorbed into the blood. When dietary intake of these vitamins is low in an individual, the colon plays a significant role in minimizing vitamin ...

While some trials involving single- or multi-strain probiotics demonstrated improvements in symptoms and quality of life for patients with chronic diarrhea, particularly in defe- cation frequency, stool consistency, and health status18–20, there have been studies reported no improvement in ...
Many microbe-derived metabolites, including bile acids (BAs), short-chain fatty acids (SCFAs), and amino acids, are involved in gastrointestinal inflammation and colonic homeostasis10,11. Recent studies also focus on the gut phageome, which can modify the gut microbiota and influence ...
In contrast to the majority of colonic adenocarcinomas, most small bowel lesions express cytokeratin 7; 70% also express cytokeratin 20, and the remainder test negative. Normal (non-neoplastic) small bowel mucosa tests diffusely positive for cytokeratin 20 and negative for cytokeratin 7.30 Results ...
The proportion of 5-methylTHF in stool samples that was monoglutamylated was determined on supernatant fractions treated with amylase and protease, either with or without conjugase treatment, as described above. Folates were purified from these enzyme-treated supernatants by affinity chromatography using...
