soil washing by mobilizing is one of in-situ techniques for soil decontamination. applying this technique to the contaminated soils could be followed by many environmental problems. therefore, it is important to study the effective factors on removal of heavy metals from different forms. in the present research, the forms of zn, pb, and cd in three contaminated soils from the zinc-lead smelting...

This experiment was conducted to investigate the effects of different sources of zinc on performance, egg quality, and immune system and blood parameters of Japanese laying quails. Total of 160 layer quails were allocated in 4 treatments include: 1) Basic diet as control, 2) Basic diet + 50 mg zinc/kg of diet from nano zinc oxide (n-ZnO), 3) Basic diet + 50 mg zinc/kg of diet from Availa-Zn as ...

The sub-retinal pigment epithelial deposits that are a hallmark of age-related macular degeneration contain both C3b and millimolar levels of zinc. C3 is the central protein of complement, whereas C3u is formed by the spontaneous hydrolysis of the thioester bridge in C3. During activation, C3 is cleaved to form active C3b, then C3b is inactivated by Factor I and Factor H to form the C3c and C3d...

Information about forms of zinc (Zn) is important for the evaluation of its status in soil and also understanding of the soil fertility and chemistry. To obtain such information, amounts and distribution of Zn in different fractions of 20 soil samples of Tehran province, Iran were determined by sequential extraction method and their relationships with each other and with soil characteristics we...

The aim of the presented study was an estimation of the zinc bioavailability derived from amino acid complexes with methionine, lysine and glycine in growing lambs. 48 lambs, Polish Merino × Romanowski × Charolaise crossbreed, at age about 10 weeks and average body weight of 20 kg were randomly divided into 4 experimental groups. Animals were kept collectively and fed with concentrate and hay i...
