Although null p-values are assumed to be uniformly distributed in gene expression experiments, the actual distribution often deviates from the assumed distribution. This can incorrectly associate the biology of a geneset with cancer prognosis in geneset-based survival studies. To assess the implications of this, a geneset-based method was developed. This method empirically approximates the distribution of null p-values and tests whether predefined sets of biologically-related genes are associate

Expansins are conserved family of non-enzymatic proteins involved in cell wall-loosening accounted for widespread role in plant development. My research focuses on functional analysis of expansins during leaf morphogenesis. Atomic force microscopy was applied to characterise cell wall mechanical properties in an attempt for in vivo quantification of expansin activity. It’s showed how that there is a distinct difference in cell wall extensibility between leaf abaxial and adaxial side.

Aim of this project is to develop a versatile and highthroughput microdevice, to be employed in studies of leukocytic chemotaxis, shear stress dependent.

Engineered bacteria provide a great opportunity to overcome the limitations of current cancer chemotherapeutics. We have developed microfluidic continuous flow-through devices as in-vitro models of tumor tissue and used them to quantify therapeutic efficacies of bacterial strains.

A PDMS “sample pretreatment” device has been fabricated in order to selectively tune key biological sample parameters which will optimize the sample for subsequent electrokinetic manipulations. We have shown that a raw sample can be homogeneously combined with specific buffers in a DC pulse micromixer in under 1.5 seconds.

The three-dimensional model of a-subunit of Biphenyl dioxygenase (BphA) from Comamonas testosteroni B-356 has been constructed. The kinetic parameters of biphenyl compounds were well matched with the docking results. The binding properties of these biphenyl compounds along with identification of critical active site residues could be used for further site-directed mutagenesis experiments in order to identify their role in activity and substrate specificity.

Functional screening of single cell clones was achieved using the HTRF® IP-One assay. The HTRF® assay from Cisbio proved to be a fast and reliable method to directly screen a large number of stable transfected single cell clones. Carbachol dose response curves with fresh cells from a growing culture and frozen instant cells showed similar results for EC50 and signal-to-blank values.

A proof of principle of a protein biochip platform permitting analysis of multiple clinically relevant proteins is presented.

A isothermal amplification termed Reverse Transcription Loop Dependant Amplification (RT-LDA) was developed with an affordable nucleic acid lateral flow detection (NALF) system, as one component of a potential POC HIV-1 RNA assay for subtypeC. RT-LDA makes use of a primer design that efficiently converts viral RNA into ssDNA amplicons, in 1 hour at 53ºC. Due to the single stranded nature of the product, the amplicon could be detected using NALF.
