Transcription Factors to Classify Tumor Types and Subtypes
Benjamin Otto 1,2, Kristin Klätschke 2, Thomas Streichert 3, Christoph Wagener 2, Genrich Tolstonog 4

Here we introduce the use of the unsupervised approach to identify transcription factors (TFs) that are specific for different tumor types.

LC-MS/MS METHOD FOR THE QUANTIFICATION OF PITOFENONE IN HUMAN PLASMA
B.M. Gurupadayya, S. Sharfuddin and R.S. Chandan

We developed LCMS/MS bioanalytical method for quantitative estimation of Pitofenone HCl in plasma is simple, sensitive, accurate, precise, and selective. Percentage recovery shows that the method is free from interference of matrix. The analytical method presented here has proved to be useful for investigation of the characteristics of Pitofenone in human plasma in pharmacokinetic and pharmacogenetic studies.

Antioxidant and Free Radicals Scavenging Activity of Biomolecules: Hydroxamic Acids
Bharati Verma and Rama Pande

In the present poster attention is focused towards the investigation of antioxidant and free radicals scavenging activity of N-aryl substituted hydroxamic acids by DPPH method which is based on the reduction of alcoholic DPPH solutions in presence of a hydrogen donating antioxidant, hydroxamic acids.

Efficacy of Gene Therapy in Restoring Vision in Leber's Congenital Amaurosis
Elizabeth O'Donnell

The research reviews current knowledge of the genetic causes of Leber's congenital amaurosis (LCA) and the development of a gene therapy intervention for LCA. The efficacy as well as the limitations of this form of treatment are evaluated in detail and recommendations are made for the future directions of gene therapy for Leber's congenital amaurosis.

METHOD DEVELOPMENT FOR THE SIMULTANEOUS DETERMINATION OF METHYLMERCURY AND INORGANIC MERCURY IN SEAFOOD
Sergio Carneado, Ariane V. Zmozinski, Carmen Ibáñez-Palomino, Àngels Sahuquillo, José Fermín López-Sánchez, Márcia M. da Silva

This work reports the method development for the simultaneous determination of methylmercury (MeHg+) and inorganic mercury (iHg) species in seafood. The study focused on the extraction and quantification of MeHg+ by liquid chromatography coupled to on-line UV irradiation and cold vapour atomic fluorescence spectroscopy (LC-UV-HG-AFS), using HCl 4 mol L-1 as extractant agent.
