Analysis of Low Levels of Bisphenol A (BPA) in Canned Broths
Ken G. Espenschied, Michael Ye, Olga I. Shimelis, and Christine Dumas

Bisphenol A (BPA) is a primary monomer used in the manufacture of many plastics and epoxies. Some of these plastics are used as beverage containers and as liners and sealants for metal food containers. Because of BPA’s potential to act as an endocrine disrupter at low concentrations in humans, regulations have been enacted regarding BPA concentrations in food and beverages sold for human consumption.

Total Phenolics and Beta-1,3-Glucans Extracted from Medicinal Mushrooms (Ganoderma lucidum, Inonotus obliquus, and Phellinus linteus)
Jaecheol Kim, Kiuk Lee, Keum Taek Hwang(1), Gichun Yoo(2)

This study was to analyze the total phenolics, beta-glucans, and beta-1,3-glucans in water extracts of three medicinal mushrooms (Ganoderma lucidum(GL), Inonotus obliquus(IO), and Phellinus linteus(PL)) under different extraction conditions.

Metabolism of Eight Model Pharmaceutical Compounds in Rat and Human HepatoPac Versus Liver Microsomes and Suspension Hepatocyte Platforms
Julius O. Enoru, William DeMaio, Adiba Watanyar, Kenneth Draper, Amanda Moore & Okey Ukairo

This poster presents our comparative metabolite profiling analysis of eight model pharmaceutical compounds with various biotransformation reactions using a functionally stable model of primary hepatocytes [micropatterned co-cultures (MPCCs)] in parallel with the traditional liver microsomal and suspension hepatocyte systems.

Characterization of Proteins and Protein Self Association (Oligomerization) with SEC-MALS
Michel Terray, Mark Pothecary

In this poster, a series of proteins and their oligomers were characterized using SEC-MALS with UV and RI detection. The monomer molecular weights are measured and compared with those from column calibration. The molecular weights of their oligomers are also compared with column calibration and the differences explored.

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.
