Busted! First Detection 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.

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.
