Design and Evaluation of High Definition Probe for HPV genotyping Microarray
Sihn Ae Lee, Ah Reum Park, Inyoung Kim, Ji Hyung Lee, and Jongwon Kim

To improve the sensitivity and specificity of the HPV DNA Microarray, we adopted triple oligonucleotide probes for each targets and selected these probes not to have higher similarity of 75% with each others. These triple probes have shown 10 ~ 100 times higher sensitivities with comparable specificities than the conventional HPV DNA microarray of single oligonuclotide probe.

Digital PCR to Determine the Number of Transcripts from Single Neurons after Patch-clamp Recording
Nóra Faragó1,2, Ágnes K. Kocsis3, Sándor Lovas3, Gábor Molnár3, Márton Rózsa3, Viktor Szemenyei3, Ágnes Zvara2, Gábor Tamás3, László G Puskás1,2

Whole-cell patch-clamp recording enables detecting electrophysiological signals from neurons, and RNA can be harvested into the patch pipette from the cells.We have optimized a dPCR protocol for determining exact transcript numbers in single neurons after patch-clamp recording by using dPCR based on high-density nanocapillary PCR.

Novel Gpr39 Agonists: Correlation Of Binding Affinity Using Label-Free Back-Scattering Interferometry With Potency In Functional Assays
Daniel Brown (1), Niklas Larsson (2), Ola Fjellström (3), Anders Johansson (3), Sara Lundqvist (2), Johan Brengdahl (2), and Richard J. Isaacs (1)

We describe the application of back-scattering interferometry (BSI) to the characterization of small molecule ligand binding to human GPR39 (a GPCR targeted for type-2 diabetes therapy) overexpressed in crude membrane fractions in free solution, including how BSI-derived affinity and functional assay-derived potency correlate for compounds of varying scaffolds.

INTERACTION BETWEEN WHEY PROTEIN NANOPARTICLES AND FATTY ACIDS
Hassan, Z.M.R*, Awad R. A.*, El-Sayed, M. M. **, Mevat I. Foda**, Otzen, D.*** and Heba H. Salama**

Nanocomplexes can be formed from WPI with good cytotoxic effect to tumer cells using cis-vaccenic and linolenic fatty acids comparable to oleic acid. It was a new interesting observation being that the nanocomplexes formed of WPI with fatty acids has a comparable cytotoxcisty to that of a-LA and ß-lg and can be used in tumor therapy.

Characterization of the prehaustorial resistance against leaf rust (Puccinia triticina f. sp. tritici) in Einkorn (Triticum monococcum) by massive analysis of cDNA ends (MACE)
Albrecht Serfling1,2, Sven Templer1,3, Dragan Perovic1, Frank Ordon1

Triticum monococcum, a valuable source for horizontal resistance against P. triticina was analyzed microscopically and by transcriptional profiling. MACE showed the increased expression of chitinases, kinases, peroxidases and pathogenesis related genes in the first 8 hai. The high number of differentially expressd tags and the knowledge about SNPs facilitates in silico mapping and the development of polymorphic markers which may accelerate the transfer of this prehaustorial resistance

Targeted cancer therapy based on blocking the expression of genes and small doses of oxaliplatin.
Bavykin A.S.1, Korotaeva A.A.1, Poyarkov S.V.2, Syrtsev A.V.1, Karpukhin A.V.1

The major drawbacks of the prescribed chemotherapy, are still remain the significant side effects and drug - resistance. Even targeted chemotherapy by means of specific antibodies do not always help to solve these complications. Our purpose was to identify potential biological targets associated with the development of drug resistance and to develop a specific method of suppressing the viability of cancer cells exposed to low doses of standard chemotherapy.
