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.

Expression Profiling of Circulating Tumor Cells: a Prognostic and Predictive Biomarker in Cancer.
Mikael Kubista, Robert Sjöback,Marie Jindrichova, Eva Rohlova, Vendula Novosadová, Siegfrid Hauch, Bahriye Aktas, Mitra Tewes,Maren Bredemeier, and SabineKasimir-Bauer

We show non-responders to treatment among breast cancer patients can be identified by expression profiling of circulating tumor cells

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.

"In-vitro studies on hydroxamic acid- CT DNA binding"
Rubi Khilari

In vitro studies of five the interaction between five different derivatives of hydroxamic acids, N-phenyl 2,4dichloro phenoxybutyro, N-m-tolyl 2,4 dichlorophenoxyglutero, N-m-tolyl-4-chlorophenoxyaceto, N-m-chloro-phenyl-tertiarybutylbenzo and N-p-tolyl-iso-valero hydroxamic acids and calf thymus DNA was investigated under simulated physiological condition.

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.

Microextraction techniques combined with X-ray fluorescence spectrometry for determination of different metal ions in water
Karina Kocot (a), Beata Zawisza (a), Eva Marguí (b), Ignasi Queralt (c), Rafal Sitko (a)

In present work new preconcentration procedures combining microextraction techniques and X-ray fluorescence spectroscopy were developed. Proposed methodologies are promising tools for multielemental analysis enabling detection of natural pollutants in different water samples.
