Quality Tools and their Application in the Production of Cellular Reagents for Screening Assays.
Sharon Davies, Lynne Smith, Lisa Bailey, Martyn Birch, Rahman Ismail, Peter Tatnell, Michelle Doyle, Liz Price and J.M Kendall, GE Healthcare

The use of mammalian cell based assays in compound screening continues to grow. Over 50% of all screening assays (HTS and HCA) now utilise cells or cell derived reagents.

Protein array-based screening of autoantibody signatures
Zingaretti C., Arigò M., Colombatto P., Brunetto M., Muratori L., Bonino F., Bianchi F., Pagani M., De Francesco R., Abrignani S., Bombaci M.

The evidence for an association between autoimmune diseases and chronic HCV infection has been clearly established. To this aim, a protein array was employed to analyze serum samples of HCV patients w/wo autoimmune complications, of patients with autoimmune hepatitis but not infected with HCV and of healthy donors as controls. A panel of autoantigens able to discriminate among the three groups of patients was identified for potential use as biomarkers.

Clinical Evaluation of human embryonic stem cells (hESCs) induced with directed differentiation to gonadotrope cells to cure vasculogenic impotency and to improve coital frequency in males. An open st
Timothy S. Andersson, David K. Chin, Wendy Hiu Wai Wong

This work demonstrates the clinical efficacy, tolerability and safety of patient-syngenic hESC induced with directed differentiation to gonadotrope cells. Hypothalamus transmits gonadotropin releasing factor to pituitary that sets off LH and FSH to Sertoli cell and Seminiferous tubule resulting Leydig cell to produces testosterone. This potential offers a rationale to evaluate hESCs to cure patients with vasculogenic impotency and to improve coital frequency in males.

Clinical Evaluation of induced pluripotent stem cells (iPSc) to cure patients with Psoriasis Vulgaris. An Open Study.
Timothy S. Andersson, David K. Chin, Wendy H. Wong

To evaluate the clinical efficacy of iPSc directed to interfere T-cell activation to cure patients with psoriasis. Twenty subjects were enrolled. Each patient was administered iv with syngenic iPS. Those showing lower PASI score were considered cured. The study states that induced iPSCs are safe and impart significant clinical efficacy to cure patients with psoriasis.

Software for Genomic/Epigenomic Research
A.S.Tanas, V.V.Shkarupo, E.B.Kuznetsova, D.V.Zaletayev, V.V. Strelnikov

We present two computer programs: 1) AIMS in silico - a suggestion tool for Amplification of Intermethylated Sites experimental design and results analysis; and 2) PeakPick – a tool to view & analyse capillary electrophoregrams Our computer software is intended to standardize AIMS applications and to turn it into one of the principal approaches towards cancer methylomes studies as well as towards diagnostics in oncology, including early screening.

Geneset-based cancer survival analysis: On the non-uniform distributiuon of p-values under the null hypothesis
Esteban Czwan, Benedikt Brors, David Kipling

Although null p-values are assumed to be uniformly distributed in gene expression experiments, the actual distribution often deviates from the assumed distribution. This can incorrectly associate the biology of a geneset with cancer prognosis in geneset-based survival studies. To assess the implications of this, a geneset-based method was developed. This method empirically approximates the distribution of null p-values and tests whether predefined sets of biologically-related genes are associate

Functional Screening of recombinant CHO-M1 cells using the PHERAstar from BMG LABTECH
Bernd Laffert1 and Franka Ganske2

Functional screening of single cell clones was achieved using the HTRF® IP-One assay. The HTRF® assay from Cisbio proved to be a fast and reliable method to directly screen a large number of stable transfected single cell clones. Carbachol dose response curves with fresh cells from a growing culture and frozen instant cells showed similar results for EC50 and signal-to-blank values.

Homology modeling and docking studies of Comamonas testosteroni B-356 biphenyl-2, 3-dioxygenase involved in degradation of polychlorinated biphenyls
M. Saqib Baig and N. Manickam

The three-dimensional model of a-subunit of Biphenyl dioxygenase (BphA) from Comamonas testosteroni B-356 has been constructed. The kinetic parameters of biphenyl compounds were well matched with the docking results. The binding properties of these biphenyl compounds along with identification of critical active site residues could be used for further site-directed mutagenesis experiments in order to identify their role in activity and substrate specificity.

Treatment of Plaque Infections and Periodontitis using Stem Cells- A New Prospect
Manoj Hariharan , Naveen Raj

Dental precursor cells are attractive for novel approaches to treat diseases like periodontitis, dental caries or to improve dental pulp healing and the regeneration of craniofacial bone and teeth. These cells are easily accessible and, in contrast to bone-marrow-derived mesenchymal stem cells, are more closely related to dental tissues. This paper gives a short overview of stem cells of dental origin.
