Hydrophilized Ultrafiltration Membranes Synthesized from Acrylic Acid Grafted Polyethersulfone for Downstream Processing of Therapeutic Insulin and Cobalamin.

The present study focuses on synthesis of novel high-performance acrylic acid (AA) grafted polyethersulfone (PES) ultrafiltration (UF) membranes for purification of small therapeutic biomolecules such as urea, insulin, and cobalamin. The membranes were indigenously synthesized by adding polyethylene glycol (PEG) of 6 kDa M.Wt.

MiSNPDb: a web-based genomic resources of tropical ecology fruit mango (Mangifera indica L.) for phylogeography and varietal differentiation.

Mango is one of the most important fruits of tropical ecological region of the world, well known for its nutritive value, aroma and taste. Its world production is >45MT worth >200 billion US dollars. Genomic resources are required for improvement in productivity and management of mango germplasm.

Probing the site-selective binding of an antiretroviral drug, Stavudine to calf thymus DNA.

The interaction of an anti-HIV drug, stavudine (STV) with calf thymus deoxyribonucleic acid (DNA) was investigated employing acridine orange (AO) as a fluorescence probe. Spectroscopic investigations revealed the intercalative mode of binding of STV to DNA. The analysis of fluorescence data indicated the presence of static quenching mechanism between STV and DNA.

Alcohol expectancy responses from teenagers: the early forewarning signals.

Background: The Indian population is overwhelmed by the rapid developmental activities in the new millennium. This has brought in urbanization and several banes of the faster life. Alcoholism is one among the menaces which have to be tackled at an early stage.

Elucidation of binding mechanism and identification of binding site for an anti HIV drug, stavudine on human blood proteins.

The binding of stavudine (STV) to two human blood proteins [human hemoglobin (HHb) and human serum albumin (HSA)] was studied in vitro under simulated physiological conditions by spectroscopic methods viz., fluorescence, UV absorption, resonance light scattering, synchronous fluorescence, circular dichroism (CD) and three-dimensional fluorescence. The binding parameters of STV-blood protein were determined from fluorescence quenching studies.
