|Validation of a 3-Dimensional Human Liver Microtissue Model for Long-term Hepatotoxicity Studies|
Brad Larson1, Stewart Hunt2, Timothy Moeller3, Diana Long4, and Peter Banks1
Non-steroidal anti-inflammatory drugs (NSAIDs) are a class of drug commonly used as analgesics and antipyretics, as well as for management of rheumatological disorders. They are one of the most highly prescribed drug families around the world, and consequently, along with antimicrobial agents, are the most frequent causes of druginduced liver injury (DILI) (Bjornsson et al., 2010).
|Liposomes and Nanoparticles as Delivery Vehicles for the Treatment of Lung Diseases|
Raisa Kiseleva1, Jennifer Mulligan2, Carl Atkinson2, Rodney Schlossser2, Alexey Vertegel1
Targeted nanoparticle-based drug delivery to the lungs is an emerging area of interest for both scientists and medical workers because it allows better drug retention in the lungs and can provide prolonged drug release. In our study we investigated the potential of using liposomes and polymeric nanoparticles surface modified with a specific antibody as drug carriers for targeted drug delivery to the lungs.
|Side by Side: An Evaluation of 2D vs. 3D Cell Culture for High Throughput Screening in Drug Discovery|
Sophie Quick 1,2, Sinead Knight 1, Jon Winter 3
•3D cell culture has the potential to provide a more physiologically relevant model compared to standard tissue culture plastic.
•From a screening perspective the technology offers the possibility of more predictive drug responses but has an increased cost.
•The question: is it possible and, more importantly, is it worthwhile moving towards screening in High Throughput using a 3D model?

|Gut Microbial Metabolites and Hepatic Xenobiotic Metabolism: A High Throughput Screening Approach|
Glynn Martin, James Sidaway, Jonathan Swann
This poster highlights the combination of metabonomics and high throughput screening by the identification of gut microbial metabolites and a screening assay designed to determine their cytotoxicity to liver-like cell cultures.
|Low Cost EIS Methodology to Characterize Microelectrode Arrays used in Biological Applications|
C. A. Santos *, M. A. Flores*, O. Pilloni* , J. Mireles Jr**., A. Falcón ***, T. Fiordelisio ***, L. Oropeza-Ramos*
Diagnostics of electrochemical impedance in micro electrodes for biological potentials measurements is essential. A low cost EIS methodology to characterize microelectrode arrays in contact with cellular medium is presented, and results are validated by comparing them to a commercial system.
|Micro array of Ag-AgCl electrodes for cellular stimulation and sensing |
O. Pilloni*, M. A. Flores*, C. A. Santos*, A. Torres**, J. García**, H. González**, L. Oropeza-Ramos*.
Silver-Silver Chloride is investigated as a fabrication material of planar microelectrodes for sensing and stimulation of excitable cells. A theoretical design method is presented. The platform was tested for different excitable tissue confirming its feasibility.
|Automated Method to Determine Infectious Dose (TCID50)|
Andrea Murphy, PhD and Catherine Swingler, PhD
Settings for each cell type and virus can be saved and re-used to assure objective results. Additional information such as cell health, cell cycle status can be determined from the same plates using Nexcelom designed applications. Time course studies can be carried out by scanning plates over several days/weeks allowing for additional information than may be generated by carrying out end-point assays alone.
