|Comparison of two different real time PCR assays and chemistry for detection of norovirus genogroup II. Method of choice? |
Toplak Nataša, Zimšek Mijovski Janet, Kovac Minka, Poljšak-Prijatelj Mateja
Noroviruses (Caliciviridae) are one of the main cause of acute non-bacterial gastroenteritis in humans. Noroviruses can not be propagated in cell cultures. Thus Real Time PCR molecular methods for caliciviral detection have been recently introduced. The aim of the study was to compare two different Real Time PCR assays for detection of norovirus strains (genogroup II) and the comparison between different RT-PCR reagents and Real Time PCR instruments was made.
|qPCRas a primary screen in drug discovery|
GauravJaggi, Frank Boeckler, Andreas Joerger and Alan Fersht
We report the use of qPCR technique to follow the thermal unfolding of proteins by the binding of the dye SYPRO Orange, and exploit its potential as a robust and high-throughput primary screen for small molecule drug discovery.
|Targeting Inflammatory Cytokines Using Adenoviruses: gene delivery of biological therapies in ovarian cancer|
Michael A. Salako, Hagen Kulbe, Iain A. McNeish, Frances R. Balkwill
Constitutive TNF-alpha expression is characteristic of the malignant ovarian surface epithelium. Adenoviral mutants hold great promise as gene therapy vectors but their efficacy is hindered by an inflammatory cascade orchestrated by TNF-alpha. We found that delivering TNF-alpha shRNA to ovarian cancer cells using oncolytic adenoviruses could reduce the inflammatory cascade generated by adenoviruses and also had direct anti-tumour activity on the cancer cells.
|Efficient downregulation of the lung liquid clearing gammaENaC subunit by RNAi|
Nihal Yueksekdag, Marei Drechsel, Christa Schmidt, and Josef Rosenecker
CF is caused by mutations in the gene encoding for CFTR. CFTR functions as chloride channel on the apical membrane of epithelia thereby regulating the transport of chloride and also sodium ions indirectly. It seems that the regulation of ENaC fails due to the mutated CFTR protein. And it is assumed that ENaC plays a role in the pathogenesis of chronic lung disease in CF-patients.
|Bayesian Parameter Estimation for Systems Biological Models of Dynamic Cellular Networks|
Jarad Niemi, Lingchong You and Mike West
Dynamic cellular networks determine production of proteins in the cells in our body. The Rb-E2F network is a key example: it controls cell cycle, proliferation and degradation - a key network in almost all cancers. We develop statistical models of such single-cell processes - fine-time scale dynamic network models. Model estimation requires informative priors and custom Metropolis proposals.

The amaxa Nucleofector® Technology is a well established method for effective, non-viral transfection of any nucleic acid substrate into hard-to-transfect cells, especially suspension and primary cells. With the
Nucleofector® 96-well Shuttle® system high throughput applications such as siRNA-library screenings have become amenable for the first time in these cell types. This renders target validation and identification possible
in cell types highly relevant for biomedical research. Here we dis
|Improving rural livelihoods through development of vegetable-based postharvest technologies in Cambodia, Lao PDR and Vietnam|
Christian Genova, Katinka Weinberger, Jun Acedo, Peter Hanson, Paul Gniffke and Manuel Palada
RETA 6208 is an ADB-funded project whose main goal is to reduce poverty, enhance rural economic development, and improve food security in Cambodia, Lao PDR, and Viet Nam through promotion of the vegetable postharvest sector. The specific objectives are to: (i) reduce postharvest losses of high volume, high value vegetable commodities; and (ii) develop and promote low-cost postharvest technologies in collaboration with both public and private sectors.

As part of the Drug Design in Medicinal Chemistry Program of the UNAM, new methylthiomorpholinphenol compounds with cardiovascular effect, were studied. One of them, FESCDIPINE II, was an excellent antihypertensive drug, that has low toxicity and preliminary studies indicate that the Angiotensin-converting enzyme (ACE) system is the biological target of this compound.
|Combination of a transient assay based ChIP technology and transcriptome analyses for the exploration of potential transcription factor binding sites|
Shu-Jen Chou (presenter), Li-Teh Chen, Yi-Hang Li, Chiung-swey Joanne Chang and Shu-Hsing Wu
1. Combination of protoplast transient expression system and Nickel resin based purification is an useful approach for chromatin enrichment that can be used to identify transcription factor’s potential target genes. 2.Comparison our ChIP-on-chip target genes with in vivo binding targets using two whole genome tiling array platforms showing high degree of overlap between two methods.
