"In-vitro studies on hydroxamic acid- CT DNA binding"
Rubi Khilari

In vitro studies of five the interaction between five different derivatives of hydroxamic acids, N-phenyl 2,4dichloro phenoxybutyro, N-m-tolyl 2,4 dichlorophenoxyglutero, N-m-tolyl-4-chlorophenoxyaceto, N-m-chloro-phenyl-tertiarybutylbenzo and N-p-tolyl-iso-valero hydroxamic acids and calf thymus DNA was investigated under simulated physiological condition.

MsCompare: An Untargeted LC & GC/MS Metabolomics Platform for Quality Control, Precise Deconvolution and Data Analysis
Marco Ruijken

A GC/MS or LC/MS workflow for Metabolomics applications includes a number of distinct steps: experimental design, sampling, sample preparation, data acquisition, data processing, deconvolution, identification and data interpretation.

The MsXelerator software includes Quality Control procedures and Analysis of Variance (ANOVA) to properly control each step in this workflow and to obtain reliable results for both quantitation and identification.

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.
