the effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (brassica napus l.) grown in the hoagland solution. the growth of treated plants was inhibited under lead stress. lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgl-1 of pb. hyola308 cultivar showed low biomass...

Abstract In an attempt to enrich the fruiting bodies with Lithium (Li), this study cultivated mushrooms using growing sets that were fortified Li 2 O at 1.0, 5.0, 10, 50, 100 and 500 mg·kg ?1 dw. Compost fortification up dw induced a dose-dependent increase in accumulation resulting median mushroom concentrations of 2.0, 8.6, 16, 29 38 dw, respectively, relative unfortified control 0.087 The do...

DNA-damaging agents induce phosphorylation of the p53 protein, resulting in its accumulation in the nucleus. To clarify the signal transduction pathway(s) involved in p53 protein accumulation in normal human embryo cells following X-irradiation, the effects of three protein kinase inhibitors were examined. Quercetin, an inhibitor of heat-shock response, dose dependently suppressed the p53 accum...

The effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (Brassica napus L.) grown in the Hoagland solution. The growth of treated plants was inhibited under lead stress. Lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgL-1 of Pb. Hyola308 cultivar showed low biomass...

introduction gallium-67 (67ga) has been used as a radionuclide for imaging a variety of solid tumors since 1969. since then use of various gallium-based radiotracers has been reported. recently, 67ga-labeled acetylacetate bis(thiosemicarbazones) (67ga-aats) complex with significant tumor accumulation and fast blood clearance has been employed. materials and methods in this study, the absorbed d...

background: the shielding methods in radiotherapy due to delivering an accurate radiation dose to cancer tissues and avoiding unnecessary dose to normal tissues are very important. these methods include lead standard blocks, individual molding and multi leaf collimator (mlc). the mlc method is not still common in iran radiotherapy centers. individual molding is better than the lead block shield...

For investigating the effect of vermicompost (VC) on improving phytoremediation of Pb by sunflower (Helianthus annuus) cultivar Lakumka, a factorial experiment was conducted in the pots containing soil or its mixture with 10% VC, in a greenhouse with controlled condition at 2018. After 3 weeks irrigation with normal water, plants were daily irrigated with high Pb-polluted water (0, 1000, 1500 o...

Background: The application of nano-particles (NPs) in various industries is growing. Since their toxicity is not clearly understood, they can cause adverse effects on the environment. The aim of this study was to evaluate the histopathological effects of iron oxide nano-particles on the small intestine of common carp, Cyprinus carpio. Methods: Four experimental treatments were designed (15 ...
