Journal of animal physiology and animal nutrition, 2011
This study was designed to evaluate the effect of heat stress on endotoxin flux across mesenteric-drained and portal-drained viscera of dairy goats. Three Saanen first lactation dairy goats were surgically fitted with indwelling catheters in the portal vein, the mesenteric vein and carotid, and were kept in thermal-neutral and then heat stress ...

Net Nutrient Flux Across the Portal-Drained Viscera and Liver of Ruminants
2016Tissues of the portal-drained viscera (PDV; reticulo-rumen, omasum, abomasum, small and large intestines, cecum, pancreas, spleen, and omental fat) and the liver are key to the digestion, absorption, transport, metabolism, and recycling of nutrients required for the maintenance, growth and lactation of ruminant animals.

Amino Acids, 2010
Cysteine is considered as a conditionally indispensable amino acid. Its dietary supply should thus be increased when endogenous synthesis cannot meet metabolic need, such as during inflammatory diseases. However, studies in animal models suggest a high first-pass extraction of dietary cysteine by the intestine, limiting the interest for an oral ...

The contribution of portal drained viscera to circadian homocysteinemia in pigs
Journal of Animal Science, 2012Homocysteine (Hcy) is an intermediary S-containing amino acid produced by the methylation process within all cells. It is known as a powerful pro-oxidant with multiple deleterious effects on immune and physiological functions. Blood plasma total Hcy (tHcy), the most common indicator of Hcy status, can be reduced by dietary folates or vitamin B(12) in ...

The effect of diet asynchrony on portal-drained viscera metabolism
Proceedings of the British Society of Animal Science, 1997Synchronising the rate of rumen breakdown and availability of dietary energy and nitrogenous components can improve the capture of rumen degradable nitrogen and improve the amount and efficiency of rumen microbial protein synthesis. It is not clear what influence rumen synchrony has on nutrient use by the portal-drained viscera (PDV).

Altered glutamine metabolism in rat portal drained viscera and hindquarter during hyperammonemia
Gastroenterology, 1992In normal rats, muscle is the major glutamine releasing organ and gut is the major glutamine consuming organ. It has been suggested that enhanced muscle ammonia detoxification and gut ammonia production occurs during liver insufficiency-induced hyperammonemia.

Oxygen Consumption and Metabolite Flux of Bovine Portal-Drained Viscera and Liver
The Journal of Nutrition, 1987Oxygen (O2) uptake and net metabolite flux by portal-drained viscera (PDV) and hepatic (HEP) tissues have been quantitated in vivo by measuring blood flow and arteriovenous concentration differences in cattle with chronic indwelling catheters in appropriate blood vessels.

Metabolic flux measurements across portal drained viscera, liver, kidney and hindquarter in mice
Laboratory Animals, 2001A method was developed to measure metabolic fluxes across either portally-drained viscera (PDV) and liver or kidney and hindquarter (HQ) in anesthetized mice. The method includes a primed-constant infusion of ketamine-medetomidine anaesthesia to stabilize the mice for the surgical procedures.
