Nanoparticles are described as substances with at least one exterior dimension between 1 and 100 nm. can be produced by physical, chemical, or biological processes. Nanoparticle production techniques include chemical reduction, electrochemistry, photochemistry, physical vapour condensation. However, some of these methods very expensive risky. The method for creating nanoparticles is simple, qui...

an experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against newcastle disease vaccine (ndv) virus in broiler chickens. a total of 160 ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...

BACKGROUND Penicillamine, once considered the cornerstone of treatment for Wilson disease (WD), is rather expensive and toxic, and often causes neurological worsening. Zinc sulphate, aiming at the treatment of free-copper toxicosis, has emerged as effective, safe and cheap alternative. AIM To assess the effect of withdrawal of penicillamine from maintenance treatment with penicillamine and zi...

Fe2O3 and ZnO nanoparticles were synthesized by a fast microwave method. Nanostructures were characterized by X-ray diffraction  and scanning electron microscopy. The goal of bio-fortification is to develop plants that have an increased content of bioavailable nutrients in their edible parts. The micronutrients magnesium (Mg), manganese (Mn) and copper (Cu), boron (B) and calcium (Ca) are essen...

background: artemia urmiana are small crustaceans that because of its non-selective filter feeder pattern potentially may absorb high level of heavy metals through their living environment. in this study, the effects of different levels of cadmium and copper on survival, catalase activity and metals bioconcentration rates in a. urmiana nauplii have been investigated. methods: the research was c...

An experiment was conducted to evaluate the effects of high dietary levels of selenium (as sodium selenite) and copper (as copper sulphate) on growth performance, serum biochemical parameters and antibody production against Newcastle disease vaccine (NDV) virus in broiler chickens. A total of 160 Ross 308 unsexed day old broiler chickens were randomly allocated into four treatment groups (n=40 ...
