The anti-plasmodial activity of different solvent extracts of Adhatoda vasica (root), Caesalpinia pulcherrima (leaf), Carica papaya (pulp), Erythroxylum monogynum (leaf), Lantana camara (whole plant), Ocimum sanctum (root) and Phyllanthus niruri (whole plant) were studied against Plasmodium falciparum. Of the 35 extracts tested, seven extracts showed good(More)
Fungal strain, Aspergillus clavatus MTCC1323 under solid state fermentation was found to produce enzymes (protease, amylase and pectinase) having potential of degrading the biofilms of Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus. Maximum specific enzyme activities were found to be 10.0, 8.0, and 10.086 U/mg for protease, amylase and(More)
During the search for a potent antifungal drug, a cell-permeable metabolite was isolated from a soil isolate taxonomically identified as Penicillium radicum. The strain was found to be a potent antifungal agent. Production conditions of the active compound were optimized and the active compound was isolated, purified, characterized and identified as a(More)
Optimization of production medium is required to maximize the metabolite yield. This can be achieved by using a wide range of techniques from classical "one-factor-at-a-time" to modern statistical and mathematical techniques, viz. artificial neural network (ANN), genetic algorithm (GA) etc. Every technique comes with its own advantages and disadvantages,(More)
For a commercially viable recombinant intracellular protein production process, efficient cell lysis and protein release is a major bottleneck. The recovery of recombinant protein, cholesterol oxidase (COD) was studied in a continuous bead milling process. A full factorial response surface methodology (RSM) design was employed and compared to artificial(More)
The search for novel bioactive compounds from the natural environment has rapidly been gaining momentum with the increase in multi-drug resistant (MDR) pathogens. In the present study, the antimicrobial potential of novel actinomycetes has been evaluated by initial screening of six soil samples. Primary and secondary screening was performed against Bacillus(More)
Cholesterol oxidase (COD) is a bi-functional FAD-containing oxidoreductase which catalyzes the oxidation of cholesterol into 4-cholesten-3-one. The wider biological functions and clinical applications of COD have urged the screening, isolation and characterization of newer microbes from diverse habitats as a source of COD and optimization and(More)
Statistics is an integral part of Clinical Trials. Elements of statistics span Clinical Trial design, data monitoring, analyses and reporting. A solid understanding of statistical concepts by clinicians improves the comprehension and the resulting quality of Clinical Trials. In biomedical research it has been seen that researcher frequently use t-test and(More)
This study consists of a pure statistical model for estimating the rate of spread of Human Immunodeficiency Virus as well as AIDS with the help of available secondary data of Uttar Pradesh. Data on some applicable variables like year of test, age group, gender, mode of transmitting disease and the percentage which is positive while testing were analyzed.(More)
Traditional methods of species classification and identification of the organism are based on morphological, physiological, biochemical, developmental and nutritional characteristics. Accurate assignment of taxonomic status to the new biologically active microbial isolates through existing bioinformatics methods is now very essential and also helpful in(More)
