Nodal involvement in bladder cancer is an independent indicator of prognosis. This study employed an iterative machine learning process called genetic programming on quantitative expression values of 70 genes to classify primary urothelial carcinoma samples into those associated with or without nodal metastasis. The generated rules showed a strong predilection for ICAM1, MAP2K6 and KDR resulting in gene expression motifs that cumulatively suggested a pattern ICAM1>MAP2K6>KDR for node positive ca
|Interactive Transcription Maps Over Microarray Data|
Petr Krontorad, Irena Koutna and Michal Strehovsky
For final description of microarray experiment results it is necessary to use some statistically robust method. Transcription maps (TM) are used to map results of gene expression analysis into individual chromosomes. We have implemented graphical tool for interactive display of TMs. This tool allows displaying of arbitrary information for each gene.
|Whole Body Endogenous Nitric Oxide Production in Patients with Decompensated Liver Disease|
Demoncheaux E., Elphick D.A., Dürner M.B., Higgins G.E., Crowther D., Williams E.J., Higenbottam T.W and Gleeson D
Increased nitric oxide (NO) production has been implicated in the pathogenesis of the hyperdynamic circulation found in patients with advanced liver disease. There were no differences between patients with liver disease and controls with regard whole body NO production. Our results, in a well characterised set of patients, argue against greater basal NOS-dependent whole body NO production in patients with decompensated liver disease.
|Caveolin-1 Expression as a Possible Biomarker in Pancreatic Cancer Diagnosis|
C. Tanase, E. Raducan, L. Albulescu, E. Codorean, M.I. Nicolescu, D.I. Popescu, M.L. Cruceru and A.C. Popa
Caveolin1 (Cav-1) function either as a tumor supressor or as a promoter of metastasis. Overexpresion of cav-1 was correlated with: tumoral grading, proliferration markers (Ki67, p53), serum tumor markers (CEA, CA19.9) and angiogenic markers (VEGF, bFGF).
|A Novel Miniaturized Cell Lysis Device Using Spherically Focused Ultrasound|
Gang Li, Hong Xiao, Min Guo and Jing Cheng
A prototype of miniaturized cell lysis device has been developed using a spherically concave transducer, which is capable of lysing bacteria in absence of added chemical denaturants or enzymes and lysing yeast efficiently without any mechanical or enzymatic pretreatment.
|EuroGentest: Reference Materials for Genetic Testing|
David E Barton, David Gancberg, Philippe Corbisier, Sarah Berwouts, Elisabeth Dequeker and Christine Brady
The lack of reference materials (RMs) for most genetic tests causes difficulties in validating and developing new assays, and results in tests being run without proper quality controls. EuroGentest and the EU-funded network for Medical Genetics, is addressing this issue by defining the present and future needs for RMs, setting priorities for and supporting the development of new RMs and building an enduring network involving all stakeholders in RM development.
|Preliminary Report: The Geriatric Propamed Study: Prospective pharmacopgenetics in geriatrics|
Dr LS Griffith, Dr L Chialda and Dr A Pahl
In a worldwide first proscpective phamacogenetic study preliminary results show reduction of adverse drug reactions and hospitilisation stays for geriatric patients after pharmacogenetic testing and medication interaction analysis to fit the medicine to the patient.
|Development of a Lab-on-a-Chip for the Characterization of Human Cells |
Richter, L., Stepper, C., Mak, A., Brückl, H. and Ertl, P.
Cell chips are developed to continuously monitor mammalian cell population dynamics in a non-invasive manner. In the presented work we describe the design, fabrication and characterization of a lab-on-a-chip for quantitative cell analysis.
|Label-free Identification of Microorganisms using a Contact-less Dielectric Microsensor|
Ertl, P., Richter, L., Reinthaler, A., Stepper, C., Mak, A., Kast, M., Heer, R. and Brückl, H.
Microfabricated biochips are developed to continuously monitor cell population dynamics in a non-invasive manner. In the presented work we describe the novel combination of contact-less dielectric microsensors and microfluidics to promote biofilm formation for quantitative cell analysis.
