Gut Microbial Metabolites and Hepatic Xenobiotic Metabolism: A High Throughput Screening Approach
Glynn Martin, James Sidaway, Jonathan Swann

This poster highlights the combination of metabonomics and high throughput screening by the identification of gut microbial metabolites and a screening assay designed to determine their cytotoxicity to liver-like cell cultures.

Searching for Urinary Biomarkers of Exposure to Heterocyclic Amines (HCAs)
Rosa Busquets, Henrik L. Frandsen, Kerstin Skog

Heterocyclic amines (HCAs) are foodborne carcinogens present in cooked meat and fish, mainly. Metabolites of HCAs have been determined in urine from volunteers following a controlled meal.

DPPH scavenging activities of selected flavonoids and their mixtures
Brachos D.(1)

The aim is to identify the ati-oxidant activity of selected flavonoids (quercetin, luteolin and galangin) and their mixtures using DPPH method including their synergistic or antagonistic interactions.

Correlation between plasma levels of lutein and oxidized low density lipoproteins: a short human intervention study
Tiziana Bacchetti, Gianna Ferretti

The increase of plasma carotenoids, in particular lutein, after dietary treatment for two weeks is associated with a significant protective effect against lipid peroxidation of plasma lipoproteins.

Strategic Utilization of Gas Chromatography with Both Nominal and High Resolution Time-of-Flight Mass Spectrometers for Metabolomic Studies
David E. Alonso, Jeff Patrick, and Joe Binkley

The Pegasus series of mass spectrometers are indispensable tools for metabolomics research:
GC-HRT analyses resulted in confident metabolite identifications:
-Spectral similarity searches
-Formulae for fragment, molecular, and adduct ions

Myth Busters: The Truth About Metabolomics and High Resolution Gas Chromatography Time-of-Flight Mass Spectrometry
David E. Alonso, Joe Binkley, and Lorne Fell

The data summarized in this presentation dispels myths associated with the utilization of GC-MS for analytes which are critical for metabolomic studies. GC-HRT provides high quality, accurate mass data for:
-Spectral similarity searches (NIST, Wiley, etc.)
-Formula determination (fragment, molecular & adduct ions)
-GC-HRT is an indispensible tool for the analysis of complex biological samples.
