Leucine metabolism following a peritoneal aminoacid load

Insulin, Glucagon, C-Peptide and Aminoacid Levels Following Liver Transplantation

Detection of peritoneal pseudocyst following ventriculo-peritoneal shunt by radionuclide method [Persian]

A 14 years old boy who had a ventriculo-peritoneal shunt since the age of 5 months, was hospitalized due to headaches, nausea, vomiting and abdominal distension. In abdominal CT and sonographic evaluation, pancreatic pseudocyst or mesentric cyst were suspected. Evaluation of the shunt by radionuclide, however, was diagnostic and revealed a pseudocyst at the peritoneal end of the shunt. Th...

Leucine and tryptophan metabolism in rats.

The rate of tryptophan metabolism in isolated liver cells from animals fed on a high-leucine diet was greater than for cells from control animals. Leucine inhibited tryptophan metabolism and tryptophan uptake in isolated liver cells, probably by competing for membrane transport. Leucine had no effect on tryptophan 2,3-dioxygenase in vitro. 4-Methyl-2-oxovalerate increased tryptophan oxidation i...

Hypothalamic Leucine Metabolism Regulates Liver Glucose Production

Amino acids profoundly affect insulin action and glucose metabolism in mammals. Here, we investigated the role of the mediobasal hypothalamus (MBH), a key center involved in nutrient-dependent metabolic regulation. Specifically, we tested the novel hypothesis that the metabolism of leucine within the MBH couples the central sensing of leucine with the control of glucose production by the liver....

Leucine Metabolism in the Black Bear

Metabolism of the essential amino acid leucine was studied in 3 black bears (Ursus americanus) in February while the bears were denning and not eating or drinking and in May while they were eating and drinking normally. (U-4C) leucine was injected as a bolus intravenously, and timed samples of venous blood were obtained over an 8-day period. Total activity in plasma gradually increased in Febru...
