STAR (signal transduction and activation of RNA) proteins are a family of RNA-binding proteins that regulate post-transcriptional gene regulation events at various levels, such as pre-mRNA alternative splicing, RNA export, translation and stability. Most of these proteins are regulated by signalling pathways through post-translational modifications, such as phosphorylation and arginine methylat...

Human hair is a biological layered system composed of two major layers, the cortex and the cuticle. We show spectrally resolved ellipsometry measurements of the ellipsometric parameters Psi and Delta of single human hairs. The spectra reflect the layered nature of hair and the optical anisotropy of the hair's structure. In addition, measurements on strands of human hair show a high reproducibil...

A number of bacterial glyoxalase I enzymes are maximally activated by Ni2+ and Co2+ ions, but are inactive in the presence of Zn2+, yet these enzymes will also bind this metal ion. The structure-activity relationships between these two classes of glyoxalase I serve as important clues as to how the molecular structures of these proteins control metal-activation profiles.

Copper oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors, bio sensors, nano fluids and catalysis. In Recent past, more efforts have been received to design materials with different properties which is dependent on morphology.  In this work cupric oxide nano flakes were...

Electronic prescriptions are supported as a means to reduce adverse drug events, but the ambiguities and overspecificities of prescription semantics along with their lack of standardization reduce adoption, limit interoperability and are potential sources of error. Ontologies in the OBO Foundry, founded on realist methodology, have been successful in fostering the logical, scientifically accura...
