Bile acid excretion was studied in 9 human subjects simultaneously by the Lindstedt (Lindstedt, S. 1957. Acta Physiol. Scand. 40:1-9) isotopic turnovermethod and by fecal chemical analysis during a balance study. The identities of the fecal bile acids were confirmed by combined gas-liquid chromatography/mass spectrometry. Under the steady state conditions of the patient studies, bile acid excre...

Pelviperineology 2012; 31: 62-64 http://www.pelviperineology.org The fifth section of the book “Pelvic floor disordersImaging and Multidisciplinary Approach to Management” entitled “Fecal Incontinence” consists of twelve chapters divided into two subsections describing diagnostic modalities and management for this disorder. In the first chapter “Three-dimensional Endoluminal Ultrasonography” G....

The ability to hold stool (called continence) requires the rectum, anus and nervous system to be working normally. Two groups of muscles in the wall of the anus and rectum are responsible for holding the stool in the rectum, the outer muscle group (external anal sphincter) and the inner muscle group (internal anal sphincter). Your ability to sense the presence of stool in the rectum (called rec...

idiarrhea is known as the current and economic disease among new born calves. it is characterized by dehydration, loss of macro-minerals, weakness, recumbency and death. in calves diarrhea with different etiology, loss of liquid and electrolytes are the principle signs and the cause of death too. therefore, determination of the amounts of liquid and mainly electrolytes depletion is important in...

Because of potential significance of fecal mutagens and secondary bile acids in the pathogenesis of colonic cancer and of inverse association between dietary fiber and colonic cancer risk, the effect of dietary wheat and rye fiber on fecal mutagenic activity and bile acid levels was studied in 15 healthy men and women who were consuming high fat/moderately low fiber diets and excreting high lev...

There is a great need to detect gastrointestinal tract cancer at an early stage. It is well known that most carcinoma tissues of the gastrointestinal tract contain carcinoembryonic antigen (CEA). Stools are a rich source of cells derived from the gastrointestinal tract. We analyzed total fecal CEA in 60 gastrointestinal tract cancer patients, 20 benign gastrointestinal tract disorder patients, ...

BACKGROUND Rotaviral diarrhea (RD) has been associated with the biodiversity of the fecal microbiota in infants; however, the differences in the biodiversity of the fecal microbiota between infants with RD and healthy (H) infants have not been clearly elucidated. OBJECTIVES This study aimed to reveal the changes in the biodiversity of the fecal microbiota of infants with RD. PATIENTS AND ME...

OBJECTIVE Environmental factors driving the development of type 1 diabetes (T1D) are still largely unknown. Both animal and human studies have shown an association between altered fecal microbiota composition, impaired production of short-chain fatty acids (SCFA) and T1D onset. However, observational evidence on SCFA and fecal and oral microbiota in adults with longstanding T1D vs healthy contr...

BACKGROUND Fecal lactoferrin has been introduced as a useful tool for the diagnosis and monitoring of inflammatory bowel disease (IBD). The aim of this study was to assess if fecal lactoferrin can be employed to predict or estimate the effect of granulocyte and monocyte adsorptive apheresis (GMA) in ulcerative colitis (UC). METHODS This was a prospective study involving 21 patients with UC. P...

OBJECTIVE To determine whether longitudinal measurements of fecal S100A12, a fecal marker of intestinal inflammation, can identify very low birth weight infants at risk for necrotizing enterocolitis (NEC). STUDY DESIGN This prospective study included 145 preterm infants with birth weight <1500 g. Meconium and stool samples (n = 843) were collected prospectively on alternate days for 4 weeks, ...
