Assessment of protein modifications in liver of rats under chronic treatment with paracetamol (acetaminophen) using two complementary mass spectrometry-based metabolomic approaches.
J. Proteomics 120 , 194-203, (2015) Liver protein can be altered under paracetamol (APAP) treatment. APAP-protein adducts and other protein modifications (oxidation/nitration, expression) play a role in hepatotoxicity induced by acute overdoses, but it is unknown whether liver protein modificat... |

Enhanced Indirect Photochemical Transformation of Histidine and Histamine through Association with Chromophoric Dissolved Organic Matter.
Environ. Sci. Technol. 49 , 5511-9, (2015) Photochemical transformations greatly affect the stability and fate of amino acids (AAs) in sunlit aquatic ecosystems. Whereas the direct phototransformation of dissolved AAs is well investigated, their indirect photolysis in the presence of chromophoric diss... |

Use of Commercial Dry Yeast Products Rich in Mannoproteins for White and Rosé Sparkling Wine Elaboration.
J. Agric. Food Chem. 63 , 5670-81, (2015) In sparkling wines, mannoproteins released during yeast autolysis largely affect their final quality. This process is very slow and may take several months. The aim of this work was to study the effect of several commercial dry yeast autolysates on the chemic... |

Renal clearance of branched-chain L-amino and 2-oxo acids in maple syrup urine disease.
J. Inherit. Metab. Dis. 22(6) , 706-22, (1999) In maple syrup urine disease (MSUD), branched-chain L-amino (BCAA) and 2-oxo acids (BCOA) accumulate in body fluids owing to an inherited deficiency of branched-chain 2-oxo acid dehydrogenase complex activity. In MSUD, little information is available on the s... |

Key aromatic residues at subsites +2 and +3 of glycoside hydrolase family 31 α-glucosidase contribute to recognition of long-chain substrates.
Biochim. Biophys. Acta 1834(1) , 329-35, (2013) Glycoside hydrolase family 31 α-glucosidases (31AGs) show various specificities for maltooligosaccharides according to chain length. Aspergillus niger α-glucosidase (ANG) is specific for short-chain substrates with the highest k(cat)/K(m) for maltotriose, whi... |

Automated screening of urine samples for carbohydrates, organic and amino acids after treatment with urease.
J. Chromatogr. A. 562(1-2) , 125-38, (1991) Eighty-five clinical urine samples and nineteen urine samples previously found by other laboratories to suggest genetic metabolic defects were prepared for trimethylsilylation by treatment with urease, followed by azeotropic dehydration. The "Target Analyte S... |
