Objective(s): Aberrant expression of CCL5 has been found in several kinds of inflammatory diseases, and the roles of CCL5 in these diseases have also been reported. However, the role of CCL5 in infantile pneumonia is still unclear. Thus, the function and acting mechanism of CCL5 in the in vitro model of infantile pneumonia were researched in this study. Materials and Methods: Human fetal lung f...

electron transport system (ets) activity was found to be related to the initial inoculum size,culturability and viability of e. coli. in this experiment, ets activity of flexibacter chinensis was measuredby int-method under a variety of conditions such as starvation media with different amendments anddifferent temperatures. the relation between ets activity, cell culturability, and viability wa...

objective(s): this study focused on determining cytotoxic effects of copper oxide nanoparticles (cuo nps) on chronic myeloid leukemia (cml) k562 cell line in a cell-specific manner and its possible mechanism of cell death. we investigated the cytotoxicity of cuo nps against k562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). materials and methods: the toxicity w...

introduction: the tumor suppressor p53 protein can induce apoptosis in some cellular contexts. among the apoptosis-inducing genes, p53 has received the most attention for cancer gene therapy. in this study, the role of dendrosome and lipofectin mediated normal cdna of tp53 into molt-4, ccrf-cem(t-iymphoma) and k562 cell lines was assessed. material and methods: at first, ccrf-cem, mol t-4 and k...

conclusions collectively, the v. pumilum extracts showed remarkable cytotoxic activity and merit further investigation as anticancer agents. results the ch2cl2 fraction of v. pumilum showed a potent dose-related inhibitory effect on cell viability. the ch2cl2 fraction showed ic50 values of 8.3 and 12.5 µg/ml in the k562 and hl-60 cell lines, respectively. a sub-g1 peak in the flow cytometry his...

objective: osteon has been introduced as a bone substitute material. it is biphasic calcium phosphate (bcp) that use in dentistry. the aim of the present study was to evaluate the effect of osteon on the proliferation, cell viability and differentiation of saos-2 cells in vitro. also it was compared with cerasorb bone graft. materials and methods: two different bone grafts materials, osteon an...

in spite of serious cardiotoxicity side-effects, doxorubicin is frequently used for treatment of several types of cancers. isolated human adult cardiomyocytes could be the best model for assessing drug-induced cardiotoxicity, while harvesting mature cardiomyocytes is restricted by some limitations such as biopsy size, cell numbers, viability, proliferative capacity and their disability to be pa...

Estradiol valerate (Exogenous estrogen) is a synthetic ester and is also a female estrogen hormone. There arestudies showing that estradiol may have anticancer effects. This study was performed to reveal the effects ofexogenous estrogens on the viability of cervical cancer cells in cell culture. We used Hela cells as our cell linein this study. Hela cells were exposed to 0.0001, 0.001, 0.01, 0....
