Urinary metabolic fingerprinting of mice with diet-induced metabolic derangements by parallel dual secondary column-dual detection two-dimensional comprehensive gas chromatography.
J. Chromatogr. A. 1361 , 265-76, (2014) This study investigates the potential of a parallel dual secondary column-dual detection two-dimensional comprehensive GC platform (GC×2GC-MS/FID) for metabolic profiling and fingerprinting of mouse urine. Samples were obtained from a murine model that mimics... |

Inhaled lactonase reduces Pseudomonas aeruginosa quorum sensing and mortality in rat pneumonia.
PLoS ONE 9(10) , e107125, (2014) The effectiveness of antibiotic molecules in treating Pseudomonas aeruginosa pneumonia is reduced as a result of the dissemination of bacterial resistance. The existence of bacterial communication systems, such as quorum sensing, has provided new opportunitie... |

Abiogenic Syntheses of Lipoamino Acids and Lipopeptides and their Prebiotic Significance.
Orig. Life Evol. Biosph. 45 , 427-37, (2015) Researchers have formed peptide bonds under a variety of presumed prebiotic conditions. Here it is proposed that these same conditions would have also formed amide bonds between fatty acids and amino acids, producing phosphate-free amphipathic lipoamino acids... |

Low resolution X-ray structure of γ-glutamyltranspeptidase from Bacillus licheniformis: opened active site cleft and a cluster of acid residues potentially involved in the recognition of a metal ion.
Biochim. Biophys. Acta 1844(9) , 1523-9, (2014) γ-Glutamyltranspeptidases (γ-GTs) cleave the γ-glutamyl amide bond of glutathione and transfer the released γ-glutamyl group to water (hydrolysis) or acceptor amino acids (transpeptidation). These ubiquitous enzymes play a key role in the biosynthesis and deg... |

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... |

Prediction of skeletal muscle and fat mass in patients with advanced cancer using a metabolomic approach.
J. Nutr. 142(1) , 14-21, (2012) Urine and plasma metabolites originate from endogenous metabolic pathways in different organs and exogenous sources (diet). Urine and plasma were obtained from advanced cancer patients and investigated to determine if variations in lean and fat mass, dietary ... |

Metabolomic profiles delineate potential role for sarcosine in prostate cancer progression.
Nature 457(7231) , 910-4, (2009) Multiple, complex molecular events characterize cancer development and progression. Deciphering the molecular networks that distinguish organ-confined disease from metastatic disease may lead to the identification of critical biomarkers for cancer invasion an... |

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... |
