Specific functions of RNA molecules are often associated with different motifs in the RNA structure. The key feature that forms such an RNA motif is the combination of sequence and structure properties. In this paper we introduce a new RNA sequence-structure comparison method which maintains exact matching substructures. ...

Gene prioritization based on background knowledge mined from literature has become an important method for the analysis of results from high-throughput experimental assays such as gene expression microarrays, RNAi screens and genomewide association studies. We apply our gene mention identifier, which achieved the best ...

Solving problems in bioinformatics often needs extensive computational power. Current trends in processor architecture, especially massive multi-core processors for graphic cards, combine a large number of cores into a single chip to improve the overall performance. The Compute Unified Device Architecture (CUDA) provides ...

A comparative interaction detection paradigm is proposed to study the complex gene regulatory networks that control cell proliferation during development. Instead of attempting to reconstruct the entire cell cycle regulatory network from temporal transcript data, differential interactions – represented by generalized ...

Graphs are often used to describe and analyze the geometry and physicochemical composition of biomolecular structures, such as chemical compounds and protein active sites. A key problem in graph-based structure analysis is to define a measure of similarity that enables a meaningful comparison of such structures. In this ...

Resistance testing is an important tool in today's anti-HIV therapy management for improving the success of antiretroviral therapy. Routinely, the genetic sequence of viral target proteins is obtained. These sequences are then inspected for mutations that might confer resistance to antiretroviral drugs. However, ...

Enzymes and other proteins coded by nuclear genes are targeted towards various compartments in the plant cell. Here, we describe a method by which localisation of enzymes in a plant cell may be predicted based on their transcription profile in conjunction with analysis of the structure of the metabolic network. This ...

Understanding complex biological systems requires data from manifold biological levels. Often this data is analysed in some meaningful context, for example, by integrating it into biological networks. However, spatial data given as 2D images or 3D volumes is commonly not taken into consideration and analysed separately. ...

We present a wiki-based interface for multiple-stage mass spectra with molecular structures and their physicochemical properties. Spectra for 453 metabolites were measured on QqTOF-MSn and their ion peaks were annotated with consideration of fragmentation patterns, especially bond cleavages. The resulting information was ...
