abstract background: high temperatures have destructive effects on cancer cells by damaging proteins and structures within cells. gold nanoparticles (aunps) can act as drug delivery vehicles, especially for cancer therapy. due to the selective intake of asparagine molecules into malignant cells, aunps were coated with asparagine; and ccrf-cem human t-cell leukemia cells were treated with the ne...
this study was conducted to find out the influence of in vitro salinity on growth parameters shoot length, number of leaves, number of new buds, the chlorophyll, chlorosis and necrosis and absorption of sodium, chloride, potassium, nitrogen and phosphorus of pear (pyrus communis cv. dargazi) in vitro propagated shoots. the experiment was conducted as a complete randomized design with 5 salinity...
