aim : the aim of this study is to design multi-walled carbon nanotubes (mwcnts) loaded with paclitaxel (ptx) anti-cancer drug and investigate its anti-cancerous efficacy of human gastric cancer. the sidewall surfaces of pristine mwcnts are highly hydrophobic. a major goal in carbon nanotube chemistry has been functionalization for aqueous solubility, and exploiting nano-tubes as macromolecules ...

The objective of the study was to investigate the inhibitory effect of Drynaria fortunei extract on human myeloma SP2 cells. Three different total extracts of Drynaria fortunei were obtained by reflux extraction method using different organic solvents including ethanol, methanol and petroleum ether. Their anticancer activities on SP20 cells were tested, and the maximum inhibition rate was obtai...

background: nigella sativa has been a nutritional flavoring factor and natural treatment for many ailments for so many years in medical science. earlier studies have been reported that thymoquinone (tq), an active compound of its seed, contains anticancer properties. previous studies have shown that tq induces apoptosis in breast cancer cells but it is unclear the role of p53 in the apoptotic p...

background: p19 cells are mouse embryonic carcinoma cells which contain pluripotent ability, like stem cells, to differentiate into different cell lines. there are several properties for this cell line that make it a valuable cell model for study of developmental stages. methods: at the first step, pts2-egfp coding sequence which was cloned in pucd2.hygro vector was used for transfection in to ...

recent evidences suggest that multiple myeloma phenotypes (mmps) are involved in the infiltration of multiple myeloma-affected marrow foci. in this study, the effects of arsenic trioxide on the invasive and angiogenic phenotypes of multiple myeloma (mm) cell line were assessed on a dose-response and time-course basis. multiple myeloma cell line, karpas 707, was treated with step-wise elevated c...

   The aerial parts of Stachys laxa Boiss. and Buhse.from Siah-bishe in Mazandaran province, Stachys trinervis Aitch. and Hemsl. from Karaj in Alborz province, Stachys subaphylla Rech. F. and Stachys turcomanica Trautv. from Golestan province have been collected in May 2008. Total extracts were obtained through MeOH/H2O (80/20) and then partitioned between CHCl3, EtOAc and MeOH. These fractions...

Background and objectives: ZatariamultifloraBioss. (ZM) has shown several effects in gastrointestinal, respiratory and nervous system. In this study, the effect of Z. multiflora was examined in colon cancer cell lines of Caco-2. Methods: Total extract and petroleum ether, chloroform and methanol fractions of the plant were prepared us...
