Abstract 17 Fitness is not well estimated from growth curves of individual isolates in 18 monoculture. Rather, competition experiments, which measure relative growth in 19 mixed microbial cultures, must be performed to better infer relat...

background: glioma is the most common primary brain tumor with poor prognosis. temozolomide (tmz) has been used with irradiation (ir) to treat gliomas. the aim of the present study was to evaluate the cytotoxic and radiosensitizing effect of tmz when combined with high-dose and high-dose rate of gamma irradiation in vitro. methods: two ‘u87mg’ cell lines and skin fibroblast were cultured and as...

background: human dental stem cells have high proliferative potential for self-renewal that is important to the regenerative capacity of the tissue. objective: the aim was to isolate human dental pulp stem cells (dpsc), periodontal ligament stem cells (pdlsc) and periapical follicle stem cells (pafsc) for their potential role in tissue regeneration. materials and methods: in this experimental s...

background: various mtt assay methods are proposed to obtain the cell sur- vival parameters. objective: determining the survival curve characteristics of two cancerous cells of interest based on a common and a novel mtt assay method after exposing them to ionizing radiation. method: a common and a novel mtt assay method were used and compared for obtaining the f10b16 melanoma and 4t1 breast ade...

this study attempts to investigate the relationship between pollution and economic growth for two groups of countries according to environmental kuznets curve hypothesis for a sample of 24 developing countries and 26 oecd countries over the period 1980 - 2005. then, we examine this hypothesis using modern econometrics techniques including panel co-integration and panel unit-root. the panel data...
