• 15941893(glutamine): Glutamine-enriched enteral nutrition in very-low-birth-weight infants and effects on feeding tolerance and infectious morbidity: a randomized controlled trial.

  Glutamine depletion has negative effects on the functional integrity of the gut and leads to immunosuppression.

• 15990633(Glutamine): A randomized controlled trial of enteral glutamine supplementation in very low birth weight infants: plasma amino acid concentrations.

  Glutamine depletion has negative effects on the functional integrity of the gut and leads to immunosuppression.

• 12600870(Glutamine): Effect of parenteral glutamine supplementation on plasma amino acid concentrations in extremely low-birth-weight infants.

  Glutamine is one of the most abundant amino acids in both plasma and human milk and may be conditionally essential in premature infants.

• 6142902(Glucagon): Effects of glucagon on plasma amino acids.

  The data show that small changes (-66 pg/ml and +50 pg/ml) in basal glucagon concentrations cause plasma amino acid concentrations to change in opposite directions.

• 2913952(Amino Acids): Nitrogen metabolism in tumor bearing mice.

  In experiments with whole animals infested with a highly malignant strain of Ehrlich ascites tumor cells , serial concentrations of amino acids were determined for host plasma , ascitic fluid , and tumor cells , throughout tumor development.

• 6599917(Glutamine): [Metabolism of nitrogen in Ehrlich ascites tumor cells: role of glutamine and ammonium].

  The amount of ammonium ion in both plasma and ascites fluid from mice inoculated with Ehrlich ascites cancer was studied.

• 3732223(pyruvate kinase): Synergistic effect of ammonium and potassium ions on pyruvate kinase from Ehrlich ascites tumor cells.

  The effect of NH4 + on M2-pyruvate kinase isolated from Ehrlich ascites tumor cells was investigated.
