A mathematical model of microbial growth for limiting nutrient in a plug flow reactor which accounts for the colonization of the reactor wall surface by the microbes is formulated and studied analytically and numerically. It can be viewed as a model of the large intestine or of the fouling of a commercial bio-reactor or pipe flow. Two steady state regimes are identified, namely, the complete wa...

Two new species of Triplumaria in the order Entodiniomorphida, T. alluvia n. sp. and T. grypoclunis n. sp., are described from the large intestine of the wild African white rhinoceros. T. alluvia has three bud-shaped caudalia, one broad skeletal plate with a wavy left dorsal edge, and an axe-shaped tail flap. T. grypoclunis has three short arched caudalia, two broad skeletal plates, and a point...

causes inflammation and sores in the lining of the large intestine. The inflammation usually occurs in the rectum and lower part of the colon, but it may affect the entire colon. Most patients are treated with medications. Aminosalicylates were the first drug shown to be benefical in UC and the first widely used aminosalicylate was salfasalazine. Balsalazide is the first new oral medication in ...

Though bad odour has always been associated with animal production, it did not attract much research attention until in many countries the odour production and emission from intensified animal production caused serious nuisance and was implicated in the health problems of individuals living near animal farms. Odour from pig production facilities is generated by the microbial conversion of feed ...

We examined the effects of feeding raffinose on intestinal calcium absorption in ovariectomized rats by two separate experiments. In experiment 1, female Sprague-Dawley rats (6 wk old) were divided into two groups: sham operation and ovariectomy, and fed diets with or without raffinose (30 g/kg diet) for 4 wk. In experiment 2, ovariectomized rats with cecocolonectomy or transsection and reanast...
