Rapid electrochemical impedance spectroscopy for protein detection in Lab-on-a-Chip devices
T. Pardy(a); N. Sleptsuk(a); M. Min(a); J. Ojarand(a); T. Lakspere(a,b); K. Palm(b)

We present results in rapid solution impedance spectroscopy to detect protein interactions (antibody-antigen) in human serum. Two different serum-antibody mixtures are measured in cuvettes, interfaced with screen-printed electrodes to determine whether the experimental setup can detect differences in composition.

Advanced Microfluidic Mixing Device for the Study of Macromolecule Dynamics
Shubha Jain, F. Azam, Dr. H. N. Unni

We have developed and characterized a micro-fluidic mixer to study the macro-molecule dynamics such as kinetics of protein folding, DNA sequencing, single molecule study and detection etc. on a micro-second timescale. Numerical simulation has been performed to analyse the study of mixing performance of micro-fluidics channel.

Analysis of Terpenes Using Gas Chromatography with Vacuum Ultraviolet
Changling Qiu, Jonathan Smuts, Phillip Walsh, and Kevin A. Schug

The VUV absorption spectra for different terpenes were distinctive and differentiable. GC-VUV demonstrated the capabilities for qualitative and quantitative analysis of terpenes in turpertine mixtures. Chromatographic coeluting signals can be deconvolved by the VUV data analysis software.

Assessing Diversity in Cassava through the Application of Metabolomics
Margit Drapala, Elisabete Carvalhoa, Laura Perez-Fonsa, Elliott Pricea, L. Augusto Becerra Lopez-Lavalleb, Paul D. Frasera

In the present study metabolomic platforms have been established for Cassava and used to assess the biodiversity present in Cassava germplasm collections and elucidate underlying biochemical mechanisms associated with traits of interest.

Metabolic response to everolimus in patient-derived xenografts of triple negative breast cancer
Leslie R. Euceda1, Deborah K. Hill1,2, Endre Stokke1, Elisabetta Marangoni3, Tone F. Bathen1, Siver A. Moestue1,2

Everolimus treatment metabolic effects on TNBC PDX models were investigated using MR spectroscopy. PLS-DA successfully discriminated treated from controls and PDX expressing INPP4B and not. LMM revealed significant differences in 4/17 metabolites and two metabolite ratios between treated and controls.

Scaffold design, function and over-expression of lentiviral-based microRNAs
Angela Schoolmeesters, Melissa L. Kelley, Annaleen Vermeulen, Anja Smith, *Mayya Shveygert, *Xin Zhou, *Robert Blelloch Dharmacon, now part of GE Healthcare, 2650 Crescent Drive, Suite #100, Lafayette, CO 80026, USA

Here we describe the strategy for scaffold design, the importance of an optimal promoter, and demonstrate gene target down-regulation from the over-expression of lentiviral microRNA mimics.

Tools for studying and using small RNAs: from pathways to functions to therapies
Kenneth Chang and Gregory J. Hannon

This poster provides an overview of the tools that have been developed to understand the functions of small RNAs and, conversely, the use of small RNAs as tools. Tools that are based on small RNAs have been exploited to investigate gene function in cultured cells and in living animals. Small RNA biogenesis, discovery and functional roles are explored in detail. Screening approaches to functional genomics, in vivo methods and potential therapeutic applications are discussed.
