Glycerol and glycerol carbonate as ultraviscous solvents for mixture analysis by NMR.
J. Magn. Reson. 212(1) , 161-8, (2011) NMR of weakly polar analytes in an apolar ultraviscous solvent has recently been proposed for mixture analysis as a pertinent alternative to the DOSY experiment. The present article reports the first use of glycerol and glycerol carbonate as polar solvents fo... |

Identification of isomeric spin adducts of Leu-Tyr and Tyr-Leu free radicals using liquid chromatography-tandem mass spectrometry.
Biomed. Chromatogr. 26(1) , 51-60, (2012) Free radical species are generally short-lived due to their high reactivity and thus direct measurement and identification are often impossible. In this study we used a spin trap, 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), to trap radical intermediates formed d... |

Selective effect of zinc on uphill transport of oligopeptides into kidney brush border membrane vesicles.
FASEB J. 9 , 1112-1117, (1995) Based on the involvement of zinc in hydrolysis of peptides, we hypothesized that Zn2+ may also play a role in peptide transport. To investigate this hypothesis, kidney brush border membrane vesicles (BBMV) were incubated for 30 min with different concentratio... |

Reactivity of Tyr-Leu and Leu-Tyr dipeptides: identification of oxidation products by liquid chromatography-tandem mass spectrometry.
J. Mass Spectrom. 44(5) , 681-93, (2009) The exposure of peptides and proteins to reactive hydroxyl radicals results in covalent modifications of amino acid side-chains and protein backbone. In this study we have investigated the oxidation the isomeric peptides tyrosine-leucine (YL) and leucine-tyro... |
