By bioinformatics we predicted that miR-23b could recognize two sites in the 3’ UTR of uPA (urokinase-type plasminogen activator) and four sites in the 3’ UTR of c-met (hepatocyte growth factor receptor). miR-23b transfections in SKHep1C3 caused uPA and c-met decreased and migration and proliferation inhibition of SKHep1C3; anti-miR-23b transfection in human fibroblasts upregulated uPA and c-met. uPA and c-met shared a common microRNA that negatively regulates their expression.

Interactive Metabolomics by Diffusion NMR: Improving the Odds of Finding Needles in Haystacks

Metabolomics investigates changes in quantities of metabolites. However, blood plasma is a complex, heterogeneous mixture of components which undergo a variety of possible molecular interactions. In particular, many low molecular weight compounds (including drugs) can exist both ‘free’ in solution, bound to proteins or within organised aggregates of macromolecules. To study the effects of e.g. disease on these interactions we have developed a technique termed ‘interactive metabolomics’.

A large-scale in silico model was constructed for the simulation of the central metabolism of Rapeseed embryos. In order to validate this model, we performed constraint-based Flux Balance Analysis, through application of linear optimization methods. Further exploiting the derived model, an in silico gene deletion analysis and a systemic regulatory analysis by Singular Value Decomposition of the steady-state flux space were performed.

SYBR® Green I as a biomarker for schizophrenia
Davood Zaeifi, Mehdi Rahmati, Vahab Piranfar. Islamic Azad University of Tonekabon

The purpose of this study were to examine if the mRNA of the peripheral dopamine receptor is changed in schizophrenia patients. 50 Naive patients were enrolled. After extracting RNA from white blood cells, cDNA is synthesized. After doing the quantitative Real-time PCR, expression of D3 receptors in healthy persons and patients were compared. Results of this examinations reveals that expression of D3 receptor is increased in compared with controls sample.

Microfluidic PCR device for diagnostic pathogen detection
Johannes R. Peham, Hannes Steiner, Walter Grienauer, Rudolf Heer, Michael J. Vellekoop, Christa Nöhammer, Herbert Wiesinger. Molecular Medicine Unit

In this work a microfluidic cyclic flow PCR device is presented, which is capable of replicating the bacterial genomic DNA sequence of the 16S ribosomal RNA. The standard laboratory processing time of 3 h could be decreased to 60 min with the microfluidic reactor without loosing PCR efficiency. Integrating an optical fluorescence detector for dsDNA measurement would evolve this device into a micro total analysis system.

Knowledge of personal energy requirements in college students
Aurora Buffington, MS, RD, Richard Tandy, PhD, and Laura Kruskall, PhD, RD, CSSD, FACSM. University of Nevada, Las Vegas

This study explored whether university students were able to estimate their energy requirements within a range of calories equal to predicted Estimated Energy Requirements (EER) two standard deviations. Students significantly underestimated their EER by 700 calories (p<.001). Fewer males than expected were able to estimate energy requirements as compared to females, 41.3% vs. 20.6%, ?2 (1) = 7.236, p=.007.
