BACKGROUND AND AIM Nanoparticles can bypass conventional physiological ways of nutrient distribution and transport across tissue and cell membranes, as well as protect compounds against destruction prior to reaching their targets. In ovo administration of nanoparticles, may be seen as a new method of nano-nutrition, providing embryos with an additional quantity of nutrients. The aim of the stud...

this study aimed to investigate the effect of different concentration of zinc nano-complex on bull spermatozoa quality and pregnancy outcome after freeze-thawing process. ejaculates were collected from four holstein bulls, twice a week during four weeks. semen samples diluted with bioxcell extender containing zero (control), 10-6, 10-5, 10-4, 10-3 and 10-2 m of zinc nano-complex. the samples we...

in order to compare the effects of different spraying of nano zinc oxide and zinc oxide, the arable irrigated wheat was conducted in two separate trials in 2011-2014 lands of abadeh city.experiments were conducted in a randomized complete block design, with five treatments and five replications.in the first experiment, treatments included the application of nano zinc oxide to five levels ( 0 , ...

to study the effects of nano-zinc oxide and seed inoculation with brady rhizobium and plant growth promoting rhizobacteria on yield and some agronomic traits of soybean, a factorial experiment based on randomized complete block design with three replications was conducted in 2013 at the research farm of the islamic azad university, ardabil branch. treatments were foliar application of nano-zinc...

The objective of this study was to evaluate effects of zinc oxide nanoparticles (nano-ZnOs) as a substitute for colistin sulfate (CS) and/or zinc oxide (ZnO) on growth performance, serum enzymes, zinc deposition, intestinal morphology and epithelial barrier in weaned piglets. A total of 216 crossbred Duroc×(Landrace×Yorkshire) piglets weaned at 23 days were randomly assigned into 3 groups, whic...

ZnO nanoparticles were synthesized by a microwave-assisted chemical method. ZnO nanostructures were synthesized via a fast reaction between zinc acetate and ammonia at presence citric acid and other effective agents in chemical procedure. Nanostructures were characterized by X-ray diffraction , scanning electron microscopy. Seed yield and seed quality of safflower grown under drought stress. Th...

abstract in respect to nano-technological studies and physiological and biochemical lesions of these materials on aquatic animals, in this study we examine the toxicity effects of nano-zinc oxide (zno nps) on hematological indices of common carp (cyprinus carpio). lc50 of nano zinc oxide was determined according to the mortality at 24, 48, 72 and 96 hours, respectively. during separate experime...

Zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in Hypericum perforatum cell suspension culture. High performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in H. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...
