Zinc deficiency is a global nutritional disorder affecting majority of healthy people rather than those suffering from chronic diseases, affects about one third of people around the world and thereby causing clinical manifestations. This work represents new modality to increase the intestinal absorptivity and bioavailability of zinc from the diet by replacing traditional bulk form by zinc nanop...

Three experiments were conducted to evaluate the effect of feeding pharmacological concentrations of zinc (Zn), from organic and inorganic sources, on growth performance, plasma and tissue Zn accumulation, and Zn excretion of nursery pigs. Blood from all pigs was collected for plasma Zn determination on d 14 in Exp. 1, d 7 and 28 in Exp. 2, and d 15 in Exp. 3. In Exp. 1, 2, and 3, 90, 100, and ...

conclusions: it was concluded that increasing the concentration of zinc in the agricultural soil is harmful to beneficial microorganisms and reduces the soil fertility. a 20-ppm zinc concentration in soil is suggested to be optimal. background: zinc is an essential micronutrient used in the form of zinc sulfate in fertilizers in the agriculture production system. nitrogen-fixing microorganisms ...

Experimental embolic particles based on a novel zinc-silicate glass system have been biologically evaluated for potential consideration in transcatheter arterial embolization procedures. In addition to controlling the cytotoxicity and haemocompatibility for such embolic particles, its glass structure may mediate specific responses via dissolution in the physiological environment. In a 120 h in-...

Heat stress (HS) jeopardizes livestock health and productivity and both may in part be mediated by reduced intestinal integrity. Dietary zinc improves a variety of bowel diseases, which are characterized by increased intestinal permeability. Study objectives were to evaluate the effects of supplemental zinc amino acid complex (ZnAA) on intestinal integrity in heat-stressed growing pigs. Crossbr...

In view of in vivo surgical smoke studies a difference-frequency-generation (DFG) laser spectrometer (spectral range 2900-3144 cm(-1)) and a Fourier-transform infrared (FTIR) spectrometer were employed for infrared absorption spectroscopy. The chemical composition of smoke produced in vitro with an electroknife by cauterization of different animal tissues in different atmospheres was investigat...

An inhalation teratology study was conducted in rats at 10, 50 and 250 ppm ethylene glycol monoethyl ether (EGEE) and in rabbits at 10, 50 and 175 ppm EGEE. This study was designed to supplement a study conducted for NIOSH which showed teratogenic effects in rats at 200 ppm EGEE and in rabbits at about 160 ppm EE. In this study, EGEE was found not to cause teratogenic effects at concentrations ...

In this study total of 150 samples emulsion type meat products (Luncheon & Frankfurter) (75 each) were collected from local and supermarkets in Giza governorate, Egypt. Samples subjected to determination residue antibiotics, zeranol, trenbolone, heavy metals (Cadmium, lead, Zinc Arsenic) pesticides (OPPs OCPs). The proved that the incidence percent organophosphorus arsenic zero all samples, zer...

the 440 fertile eggs, in a completely randomized design were divided into 11 treatments with four replicatesand 10 eggs per each replicate. treatments including: (t1; control; without injection), (t2; injected with 0.3ml saline 9.0%; sham control), (t3, t4 and t5) 25, 75, 125 ppm fe-nano, (t6, t7 and t8) 50, 100, 150 ppmfe-nano-alimet chelate, (t9, t10 and t11) 50, 100, 150 ppm fe-aliment chela...
