forage species in mixtures are extensively grown worldwide nowadays, particularly as a step towards sustainable agriculture, however, information on this topic is scanty in our country. thus a 2-year (2001-2003) field experiment was conducted to determine the forage yield, botanical composition, as well as competition of some forage grasses and legumes as mono and dual cultures combinations at ...
background: despite the wide range of applications, there is a serious lack of information on the impact of the nanoparticles on human health and the environment. the present study was done to determine the range of dangerous concentrations of iron oxide nanoparticle and their effects on mouse embryonic stem cells. methods: iron oxide nanoparticles with less than 20 nanometers diameter were enc...
introduction: cell culture is a process in which the cells ware isolated from original tissue, dispersed in liquid media and then placed in culture plate where the cells adhere together and propagate. today, this method is used for assessment of cell toxicity, its mechanisms and effect of different compounds on intracellular components. methods: clonogenic assay was used for assessment of cell ...
