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.
