Journal ArticleDOI
Incidence of methanogenic bacteria in a sigmoidoscopy population: an association of methanogenic bacteria and diverticulosis.
TL;DR: The incidence and concentration of methane-producing bacteria in tap water enema samples of 130 individuals taken before sigmoidoscopy showed that the incidence of methanogens in concentrations of 10(7)/g dry weight of faeces or greater in patients with diverticulosis was significantly greater than in normal patients.
Journal ArticleDOI
Gastrointestinal angiodysplasia associated with aortic valve disease: part of a spectrum of angiodysplasia of the gut.
TL;DR: It is suggested that angiodysplasia of the gastrointestinal tract can be regarded as a spectrum with a clearly inherited etiology on one extreme and an acquired etiology for a subset of patients associated with aortic valve disease.
Journal ArticleDOI
Short chain fatty acid distributions of enema samples from a sigmoidoscopy population: an association of high acetate and low butyrate ratios with adenomatous polyps and colon cancer.
TL;DR: The difference in proportions of individual SCFA between groups suggest differences in fermentation patterns of the colonic microflora.
Journal ArticleDOI
Acarbose Enhances Human Colonic Butyrate Production

TL;DR: Acarbose effectively augmented colonic butyrate production by several mechanisms; it reduced starch absorption, expanded concentrations of starch-fermenting and butyrates producing bacteria and inhibited starch use by acetate- and propionate-producing bacteria.
Journal ArticleDOI
Constancy of glucose and starch fermentations by two different human faecal microbial communities.
TL;DR: The fermentation of glucose and corn starch by faecal suspensions from two subjects was examined over a three and a half year period and significant differences were found in molar ratios and concentration of acetate and propionate and concentrations of butyrate in faeces.
