We have systematically studied the evolution of the photoluminescence(PL) tuning of porous silicon(PS) by electrochemical etching in various mixed electrolytes. The electrolytes employed as an etchants were mixtures of HF:CH3COOH:HNO3:C2H5OH solutions where the composition ratios (%) were varied from 10:1.98:0:88.02 to 10:1.98:8.4:79.62 under constant concentration of HF and CH3COOH with a tota...

Malaria, one of the most widespread diseases, is caused by a plasmodium parasite million people each year, results in several million deaths annually. protozoa that cause malaria, no one antimalarial drug is effective against all four species. research investigation, we performed antimalarial agents. To design a new molecule having good pha information. Key-words: TPSA, GPCR, ADMETox, Malaria i...

Cell walls are of interest to plant biochemists and cell biologists for two main reasons: they regulate cellular morphogenesis and act as structural support materials. As it is a major component of plant cell walls and a natural product of considerable commercial value, cellulose has long been a focus of interest in cell-wall biology, although it is far from the only constituent of cell walls. ...

The intracellular metabolic fluxes can be calculated by metabolic flux analysis, which uses a stoichiometric model for the intracellular reactions along with mass balances around the intracellular metabolites. In this study, we have constructed in silico metabolic pathway network of Escherichia coli consisting of 301 reactions and 294 metabolites. Metabolic flux analyses were carried out to est...

Academic researchers and many in industry often lack the financial resources available to scientists working in "big pharma." High costs include those associated with high-throughput screening and chemical synthesis. In order to address these challenges, many researchers have in part turned to alternate methodologies. Virtual screening, for example, often substitutes for high-throughput screeni...

Metagenomic characterization of complex biomes remains challenging. Here we describe a modification of digital karyotyping-biome representational in silico karyotyping (BRISK)-as a general technique for analyzing a defined representation of all DNA present in a sample. BRISK utilizes a Type IIB DNA restriction enzyme to create a defined representation of 27-mer DNAs in a sample. Massively paral...
