Threonine requirement of parenterally fed postsurgical human neonates.
BACKGROUND The threonine requirement of human neonates who receive parenteral nutrition (PN) has not been determined experimentally. OBJECTIVE The objective was to determine the parenteral threonine requirement for human neonates by using the minimally invasive indicator amino acid oxidation technique with L-[1-(13)C]phenylalanine as the indicator amino acid. DESIGN Nine postsurgical neonat...
متن کاملMetabolism of lactose-[13C]ureide and lactose-[15N,15N]ureide in normal adults consuming a diet marginally adequate in protein.
Oral lactose-ureide is resistant to human digestive enzymes, but is fermented by the colonic microflora. Nine normal adults consuming a diet which provided 36 g of protein/day were given oral doses of lactose-[(13)C]ureide and lactose-[(15)N,(15)N]ureide. The appearance on breath of (13)CO(2) derived from lactose-[(13)C]ureide was followed for 48 h. The fate of (15)N derived from lactose-[(15)N...
متن کامل1H, 13C, and 15N resonance assignment of photoactive yellow protein
Photoactive yellow protein (PYP) is involved in the negative phototactic response towards blue light of the bacterium Halorhodospira halophila. Here, we report nearly complete backbone and side chain (1)H, (13)C and (15)N resonance assignments at pH 5.8 and 20 °C of PYP in its electronic ground state.
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Intravenously infused carnitine: influence on protein and branched-chain amino acid metabolism in starved and parenterally fed rats.
We studied the effect of intravenously infused carnitine (34 mumol.100 g-1.d-1) on protein and branched-chain amino acid (BCAA) metabolism in rats either starved for 3 d or parenterally fed for 7 d. Carnitine infusion did not significantly affect nitrogen balance, protein content of liver and muscle, plasma concentrations of BCAA and branched-chain keto acid, or leucine oxidation and incorporat...
