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.

Reactome is a manually curated knowledgebase, created and peer-reviewed by experts in their field. Its robust data model describes life processes ranging from metabolism to signal transduction and the cell cycle. As of release 28, Reactome contains 3700 human proteins in 3200 reactions. Data is cross-referenced to publicly available web-based informatics resources. Reactome features the SkyPainter tool for analysis of high-throughput datasets, and the Mart query and data retrieval tool.
|Panic attack and suicide risk: A multivariate logistic regression analysis of a national epidemiological survey |
Curren Katz, Ramin Mojtabai, Leo Bierman, Kathleen Camacho, Janine Samuel, Gillian Jennings, Igor Galynker
To examine the relationship between panic attack and suicide risk, we analyzed data from a representative epidemiological survey of 43,093 adults (NESARC) using logistic regression controlling for socio-demographic and clinical variables. In depression, panic attacks are associated with increased odds of suicide attempt even after controlling for demographic and clinical variables. Furthermore, panic attacks can differentiate those who attempt suicide from those with ideation only.
