Busted! First Dection of Steroid Hormones in Pacific Walrus Bones
Charapata P, Horstmann L, and Misarti N

The Pacific walrus (Odobenus rosmarus divergens) is a candidate species for the Endangered Species List because Arctic sea ice has declined significantly in the past decades. This project focuses on validating a method for extracting steroid hormones from archaeological, historical, and modern bone creating a baseline of hormone levels during different climate regimes. The results validate our method of hormone extraction as all steroid hormones were extracted from bones of all time frames.

Ichthyophonus vs. Proteins: Should we be eating these fish?
Alisa Aist

The project, Ichthyophonus vs. Proteins, analyzes the effect of Ichthyophonus on the protein content of Halibut from Homer. This experiment found that Ichthyophonus does not have a significant effect on the protein content of the tested Halibut. The findings confirm the belief that Ichthyophonus is not harmful to humans and the Halibut are still safe to eat.

Uncertainty estimation of an analytical method for analysis of fumonisin B1 in four types of rice intended for consumption human
Petrarca, M.H.; Rossi, E.A.; Sylos, C.M.

The expanded measurement uncertainty of a sample preparation method based on QuEChERS procedure for the determination of fumonisin B1 in four types of rice, using HPLC-FLD after precolumn derivatisation with ortho-phthaldialdehyde, was estimated from in-house validation data.

Progressing 3D Spheroid Analysis into a HTS Drug Discovery Method
Sarah Kessel, Eric Sincoff, Olivier Dery

This study demonstrates that the cell culture assay for tumorsphere size was successfully adapted to 384-well plate for a 3D spheroid assay using U-bottom low attachment 384-well and the Celigo Automated Imager for image acquisition and analysis. Moreover, the utilization of an imager provided insight on sphere and cell fate after long term drug treatment.

LC-MS/MS METHOD FOR THE QUANTIFICATION OF PITOFENONE IN HUMAN PLASMA
B.M. Gurupadayya, S. Sharfuddin and R.S. Chandan

We developed LCMS/MS bioanalytical method for quantitative estimation of Pitofenone HCl in plasma is simple, sensitive, accurate, precise, and selective. Percentage recovery shows that the method is free from interference of matrix. The analytical method presented here has proved to be useful for investigation of the characteristics of Pitofenone in human plasma in pharmacokinetic and pharmacogenetic studies.
