We have measured unidirectional uptake (not transmural flux) of acetate, butyrate and proline by everted sleeves of intact tissue from the jejunum, caecum, proximal colon and distal colon of prairie voles (Microtus ochrogaster). There was active (i.e. Na(+)-dependent) transport of L-proline in the jejunum, but we found no evidence for it in any region of the hindgut (i.e. the caecum, proximal c...

Activities of twelve hydrolytic enzymes in the digestive tract of young rabbits before weaning (4 weeks old) and adult rabbits (3 months old) were measured. The principal digestive enzymes in both groups of rabbits appeared to be amylase (EC 3.2.1.1), maltase (EC 3.2.1.20), pectinase (EC 3.2.1.15) and proteinases. The stomach of young rabbits contained most of the lipolytic activity and 45.7% o...

subulura brumpti infection was observed in japanese quails and caused heavy production loss up to 10%. gross lesions were confined to caecum of the affected birds. pathological changes suggestive of acute cecal hemorrhagic enteritis were recorded. closer observation of the cecal loop revealed wavy movement with thousands of tiny worms. based on morphometry, the worms were identified as s. brump...

To determine the effect of dietary brous ingredients on intestinal microbial population and activity, 48 early–weaned (24–25 days) pigs were divided into six dietary treatments: a standard diet (STD) based on corn, barley and soybean protein; or high brous diets obtained by replacing some major ingredients of STD with 8% Wheat bran (WB), 8% Wheat middlings (WM), 6% Sugar beet pulp (SBP), 4% W...

The effects of two lubricating oils on the trophic diversity of a nematode community of a Tunisian lagoon were investigated in a microcosm experiment. Sediment from a pristine site in Ghar El Melh lagoon (Western Mediterranean) was treated with mineral oil (Mobil 20 W-50), a synthetic lubricant (Mobil 0 W-40), the same two lubricants after use in a vehicle. Univariate analysis showed significan...

Synthetic fuels are based on syngas, a mixture of CO and H2, which can be obtained from natural gas or gasification of coal and biomass. Synthetic fuels are a great drop-in fuel alternative to fossil fuels as they can help meet global energy needs, ensure energy security and reduce the carbon footprint. Mobil pioneered a revolutionary route for synthetic fuel synthesis with two stages: (1) synt...

Malignant transformation of endometriosis is rare and is usually seen in ovarian endometriosis. The colon and rectum are the most common sites for extragonadal endometriosis, and although serosal involvement is commonly seen, mucosal involvement is rare. Malignant transformation of endometriosis is a rare but a well-known complication of endometriosis. We report an unusual presentation of endom...
