TOXICITY OF SELECTED BIOACTIVATED COMPOUNDS IN PRIMARY RAT HEPATOCYTES CULTURED IN MICROPATTERNED CO-CULTURES
Okechukwu Ukairo, Julianne Shi, Justin Jackson, Kelly Rose, Melvin E. Andersen, and Edward L. LeCluyse

Drug Induced Liver Injury (DILI) modeled in a novel co-culture liver model. Here, we assess the bioactivation and cytotoxicity of acetaminophen (APAP) and other compounds in the 96-well rat MPCC.

Mixtures Analysis of Complex Mixtures
Michael Bernstein; Carlos Cobas; Santi Domínguez; Manuel Pérez; Agustín Barba

We describe an NMR method to quantify mixture components in wine, edible oils, etc. The method is fully customizable, and amenable to high throughput operation.

Comparison of Three Methods for the Evaluation of Cytokine Storm Risk in Early and Clinical Stage Biopharmaceutical Development
Gary dos Santos and Emer Clarke

Objective: To identify an assay that can accurately predict the risk of CRS and CS associated with investigational biotherapeutics. A comparison of three methods were used: (a) immobilization of test antibody on plastic, (b) co-culture of PBMC's on HUVEC's and (c) pre-culture of PBMC's at high cell density.

Isolation, Identification, and Determination of Designer Anabolic Steroids Commonly Found in Dietary Supplements
Sarah E. Voelker, M.S.; Travis M. Falconer, Ph.D.; Jonathan J. Litzau; Mary B. Jones; Lisa M. Lorenz

A general analytical approach in identifying emerging steroid-like compounds is presented, including analysis by GC-MS, LC-MS, and/or HPLC-UV. Isolation of unknown compounds was achieved by high performance liquid chromatography with fraction collection. Isolated compounds were characterized by Nuclear Magnetic Resonance spectroscopy and high resolution accurate mass-mass spectrometry to elucidate their structure.

A Mass Spectrometer for Elemental Analysis based on Fieldable Technologies
Hilary Brown, Jennifer Speer, John Gerling, and Kenyon Evans-Nguyen

Laser ablation and a Microwave Plasma Torch (MPT) were coupled in order to obtain elemental information from solid samples. The MPT was incorporated as a less costly and more portable alternative to the ICP. MPT was also added to help improve the signal from just the laser ablation alone.

Combining low and high volume liquid handling capabilities for ADME screening
Joby Jenkins, Kevin Moore, Stephen Fowler, Pascal Schenk

In this study we demonstrate the integration of two liquid handlers to extend the volume dispensing range creating low-volume assay-ready plates with high accuracy and precision. This was then successfully applied to a CYP inhibition assay.

Pharmacokinetic Delivery and Metabolizing Rate of Nicardipine Incorporated in Hydrophilic and Hydrophobic Cyclodextrins using Two-Compartment Model

The dispersion routes of cyclodextrin complexes with nicardipine (NC), such as hydrophilic hydroxypropyl-ß-cyclodextrin (NC/HPßCD) and hydrophobic triacetyl-ß-cyclodextrin (NC/TAßCD), through the body for controlled drug delivery and sustained release have been examined.

Determination of Metabolically Unstable Drugs in Blood by Heat-Stabilized DBS and LC-MS/MS

The aims of this work were to investigate drug stability prior to, during and after blood spot sampling, using procaine, prulofloxacine, esmolol, and acetylsalisylic acid as examples of drug compounds with limited stability and to compare conventional DBS sampling procedure with DBS sampling including heat stabilization.
