conclusions based on the present study, it can be concluded that oral administration of silver nanoparticles for 28 days had no effect on rat liver function, but probably led to early apoptotic stages. materials and methods in this experimental study, 40 adult male sprague-dawley rats were divided into five groups. in the four experimental groups, nanosilver particles were given orally for 28 c...

To evaluate the effect of nanosilver (5, 10 and 20 mg l-1), hydrogen peroxide (200, 400 and 600 µM) and Nanosil (200, 400 and 600 µM) as antimicrobial compounds in vase solution of cut rose cv. ‘Grand Press Angela’ flowers, an experiment with 10 treatments and 3 replications was conducted in a completely randomized design. Cut rose flowers were continuously treated with these compounds. The res...

nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. the nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. some samples of breast muscle, femora muscle, heart, gizzard, liver, skin, spleen, lung, kidney and cloacal feces were collected randomly in slaughter...

serious concerns have been expressed about potential health risks of nano silver containing consumer products (agnps) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of agnpsinbiomedicalproducts with special concerns to the mutagenic potentials. in this study, we examined the inhibitory and mutagenicity effects of agnps in three different ...

Nanosilver, due to its small particle size and enormous specific surface area, facilitates more rapid dissolution of ions than the equivalent bulk material; potentially leading to increased toxicity of nanosilver. This, coupled with their capacity to adsorb biomolecules and interact with biological receptors can mean that nanoparticles can reach sub-cellular locations leading to potentially hig...

We prove a conjecture of Micha Perles concerning simple polytopes, for a subclass that properly contains the duals of stacked and crosspolytopes. As a consequence of a special property of this subclass it also follows that, the entire combinatorial structure of a polytope in the subclass can be recovered from its graph, by applying our results recursively.
