Abstract — Fe2O3 substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. Nucleation and crystallization regimes were determined by the parameters obtained from differential thermal analysis (DTA) of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified u...

the purpose of this research was to study the antimicrobial activities of the endophytic fungi from sesbania grandiflora (l.) pers. the endophytic fungi were isolated from branches and leaves of sesbania grandiflora (l.) pers., and sixty nine isolates were obtained. all isolates were screened for antibacterial and antifungal activities. the indicator organisms were 4 bacteria including staphylo...

in this work, the template, monomer and cross-linker with the ratio of 1:8:40 were used to synthesize molecularly imprinted polymers (mips) for extraction of the bioactive chemical compounds from some traditional herbs as a sorbent material. quercetin, methacrylic acid (maa), trimethylolpropanetrimethacrylate (trim) and tetrahydrofuran (thf) were used as a template, functional monomer, cross-li...

cancer incidence is projected to increase in the future and an effectual preventive strategy is required to face this challenge. alteration of dietary habits is potentially an effective approach for reducing cancer risk. assessment of biological effects of a specific food or bioactive component that is linked to cancer and prediction of individual susceptibility as a function of nutrient-nutrie...

background and objectives: entomopathogenic nematodes, belonging to the family heterorhabditis and steinernematidae, are reported to be symbiotically associated with specific bacteria and the secondary metabolites produced by these bacteria possess antimicrobial activity. in this study, bacteria were isolated from nematodes belonging to the family rhabditidae, and the antimicrobial activity was...

background: woodfordia fruticosa is used traditionally as antidysenteric compound for fodder animals. stem and flower extracts are previously flourished for their antibacterial activity. leaves are also equally important, which are preliminary screened for their bioactive components in present study. objective: evaluation of antibacterial activity of leaves of w. fruticosa and detection of thei...

background and objectives: in the present study, isolation of streptomyces associated with marine sponges and its bioactive potential against fish and shellfish pathogens were assessed. the streptomyces sp. were isolated from the marine sponges namely callyspongia diffusa, mycale mytilorum, tedania anhelans and dysidea fragilis collected from vizhinjam port, situated in the south-west coast of ...

generation neural stem cells from neurosphere–derived bone marrow stem cells using bioactive substance atc. bone marrow cells (bmscs) were isolated from rat. bmscs cultured by dmem/f12 medium supplemented with 10% fetal bovine serum. these cells evaluated by specific markers of bmscs such as bioactive substance atc, b27. then bmscs differentionated in to neurosphere and divided in two groups wh...

in this study the bacterial growth inhibitory activity of peptide fragments produced from goat’s milk whey proteins by enzymatic hydrolysis using trypsin, ficin and a combination of both was investigated. goat’s milk whey proteins were isolated and subjected to enzymatic hydrolysis and peptides were purified by ultrafiltration followed by reverse-phase high-performance liquid chromatography (rp...
