|A Novel Approach Toward Microfluidic Drug Metabolite Synthesis – Electrosynthetic Methodology Simulating Cytochrome (CYP450) Oxidation|
Romain Stalder, Gregory P. Roth and Philip Podmore
A novel microfluidic technology and electrochemical synthesis method is demonstrated for the efficient generation of known drug metabolites. These metabolites are typically generated on first pass hepatic oxidation in vivo. The FLUX Module, a new microfluidic electrochemical cell manufactured by Syrris Ltd., has been employed to generate the metabolites of five commercial drugs: Tolbutamide, Chlorpromazine, Diclofenac, Primidone and Albendazole.
|MS Data Processing With Full Flexibility Of Universal Processing Software|
Frans Schoutsen, Barbara van Cann, Vincent Jespers, Michal Godula
Liquid Chromatography (LC) in combination with triple quadrupole Mass Spectrometry (MS) is more and more a common analysis technique in routine laboratories. Especially when using MS/MS selected reaction monitoring (SRM) for a large number of components data handling can be a bottle neck. This poster will show MS data processing of pesticides in water samples using an already established chromatography data system which is now also capable of processing large quantities of MS data.
|Analysis of Dithiocarbamate Pesticides by GC-MS|
Soma Dasgupta1,2, Sumaiyya Mujawar1, Kaushik Banerjee1, Hans-Joachim Huebschmann3, Paul Silcock4
Analysis of dithiocarbamate pesticides (DTCs) using an optimized GC-MS method is described. DTCs are not stable and cannot be extracted or analyzed directly. The purpose of this work was develop a reliable method for identification and quantification of residues.
|Analysis of Multiresidue Pesticides Present in Ayurvedic Churna by GC-MS/MS|
Manoj Surwade, Sunil T Kumar, Aarti Karkhanis, Manish Kumar, Soma Dasgupta, Hans-Joachim Huebschmann, Paul Silcock, Thermo Fisher Scientific
Analysis of Herbal powders or ‘churnas’ using an optimized GC-MS/MS method is described. As they have high amount of matrix co-extractives, they pose critical analytical problems. The purpose of this work was overcome the effect of the matrix and develop a reliable method.
|Automated Solid-Phase Extraction of Oraganochlorine Pesticides from Drinking Water|
Frans Schoustsen and Pranathi R Perati
A new method was developed to automate the capture and elution of Organochlorine pesticides from drinking water. The concentrated analytes were then analyzed by GC with Electron Capture Detection (ECD).
|GC-MS/MS Analysis of Pesticide Residue in Green Tea Extracted by QuEChERS with Acetonitrile as Final Solvent|
Cojocariu C., Morgan P., Silcock P., Godula M
QuEChERS involves an initial step when a few grams of the sample are extracted with acetonitrile followed by a clean-up step (with dispersive-SPE) used to remove, to a certain extent, unwanted matrix compound (such as pigments, sugars, organic acids). With QuEChERS, the final extract ends up with the pesticides in acetonitrile, which, being polar solvent, can be
problematic in GC-MS.
|Increasing Extraction Efficiency of Pesticides and Dioxins from Wet Samples Using a Novel Polymer During Accelerated Solvent Extraction|
Katerina Bousova, Pranathi Perati, Rahmat Ullah, Kannan Srinivasan
Thermo Scientific™ Dionex™ ASE™ Prep MAP is a proprietary polymer designed to remove moisture and increase extraction efficiencies from wet samples including soils, tissues and food products. This unique formulation allows moisture removal under a variety of ionic strength conditions and accelerated solvent extraction conditions.
|A complete workflow from sample preparation to analysis using SureSelect target enrichment system for Ion Proton semiconductor sequencing|
Christian Le Cocq, Kyeong Soo Jeong, Arjun Vadapalli, Joseph Ong, Elin Agne, Filip Karlsson, Ashutosh Ashutosh, Francisco Useche, Jayati Ghosh, Henrik Johansson, Scott Happe, Douglas Roberts, and Holly Hogrefe
Agilent’s SureSelect Target Enrichment for the Ion Proton Platform provides a comprehensive, efficient, robust, and cost-effective means to sequence subsets of the human genome.
|Evolutionary Changes in Proneural Gene Expression - atonal and ASH in Daphnia magna|
Marleen Klann & Angelika Stollewerk
The presented in this poster investigates the morphological and molecular development of sensory organs in Daphnia magna.
|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
