abstract

cancer is one of the main causes of mortality in the world which appears by the effect of enviromental physico-chemical mutagen and carcinogen agents. the identification of new cytotoxic drugs with low side effects on immune system has developed as important area in new studies of immunopharmacology. thymoquinone (tq), derived from the medicinal spice nigella sativa (also called black cumin) exhibit anti-inflammatory and anti-cancer activities. in this report we employed nanogel-based nanoparticle approach to improve upon its effectiveness. myristic acid-chitosan (ma-chitosan) nanogels were prepared by the technique of self-assembly. thymoquinone was loaded into the nanogels. the surface morphology of the prepared nanoparticles was determined using sem and tem. the other objective of this study was to examine the in vitro cytotoxic activity of cell death of thymoquinone and nanothymoquinone on human breast adenocarcinoma cell line (mcf7). cytotoxicity and viability of thymoquinone and nanothymoquinone were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (mtt) and dye exclusion assay.transmission electron microscopy confirmed the particle diameter was between 150 to 200 nm. proliferation of mcf7 cells was significantly inhibited by thymoquinone and nanothymoquinone in a concentration-dependent manner in defined times. there were significant differences in ic50 thymoquinone and nanothymoquinone. tq-loaded nanoparticles proved more effective compared to tq solution. the high drug-targeting potential and efficiency demonstrates the significant role of the anticancer properties of tq-loaded nanoparticles.

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
