Non-esterified cholesterol was determined enzymatically with the cholesterol oxidase-peroxidase reaction using phenol and 4-aminophenazone as chromogens. This assay as done in the supernatant containing the lipoprotein-X. Other serum lipoproteins were removed by precipitation with heparin and zinc acetate followed by centrifugation. No standardization was required, the lipoprotein-X concentrati...

BACKGROUND Rice as a renewable, abundant bio-resource with unique characteristics can be used as a bio-template to synthesize various functional nanomaterials. Therefore, the effect of uncooked rice flour as bio-template on physico-chemical properties, especially the morphology of zinc oxide nanostructures was investigated in this study. The ZnO particles were synthesized through hydrothermal-b...

We studied the mechanisms by which excess copper exerts, and zinc mitigates, toxic effects on HepG2 cells. Survival and cell growth were reduced in media containing greater than 500 microM copper chloride for 48 h; LD50 was 750 microM. At 1,000 microM copper for 1 h, there was a general reduction of protein synthesis, and no recognizable changes in cellular ultrastructure. Incubation of cells w...

To develop bio-packaging materials, nanocomposite films of cellulose acetate reinforced with titanium dioxide and zinc oxide nanoparticles were prepared, by the casting method at different weight ratios ZnO (1.5, 2, 2.5) wt% a constant ratio 2 TiO2. TiO2 tested using scanning electron microscopy (SEM). The mechanical properties (tensile strength elongation) improved fixed level Cellulose Acetat...

In this paper we report on the use of aerosol assisted chemical vapour deposition (AACVD) to form thin films of the zinc titanate phases using zinc acetate and titanium isopropoxide as precursors in methanol solution. Analysis by XRD and XPS found that through variation in experimental conditions we have been able to synthesize films of zinc titanate with composition of Zn2TiO4 or Zn0.3Ti2.7O4....

Nanocrystalline ZnO particles were prepared by a novel sonochemical route from zinc acetate and sodium hydroxide without any requirement of calcination steps at high temperature and without surfactants. Variations in several parameters and their effects on the structural (crystal size and morphology) properties of nanoparticles were investigated. Characterizations were carried out by X-Ray ...

Nanostructured zinc oxide is intensively studied semiconductor showing photocatalytical activity. There are several precursors which can be used for the preparation of nanostructured zinc oxide like zinc acetate, zinc sulphate and many others. Zinc chloride is another compound which can serve as a zinc source for zinc oxide preparation. Nowadays the environmental aspects connected to applicatio...

BACKGROUND Zinc gluconate and zinc acetate lozenges have been reported to shorten the duration of common colds in a dose-response manner when the amount of the active ingredient, positively charged zinc ions, is sufficient. OBJECTIVE To improve results using a zinc gluconate nasal spray with zinc orotate lozenges. DESIGN Double-blind, placebo-controlled clinical trial. SETTING Private phy...

Zinc oxide nanostructure is selectively synthesized by a simple reaction of zinc acetate dehydrate. With hexamethyltetramine (HMT) under mild hydrothermal conditions, we use zinc thin films as seed layer. Scanning electron microscopy (SEM) result shows that zinc thin films were oxidized to hexagonal ZnO seeds in the absence of zinc salt and base under hydrothermal conditions. The effect of a mi...

OBJECTIVE Children in developing countries are at a high risk for zinc deficiency. Supplemental zinc has previously been shown to provide therapeutic benefits in diarrhea. The objective of this study was to examine the efficacy and safety of supplemental oral zinc therapy during recovery from acute or persistent diarrhea. METHODS We conducted a meta-analysis of randomized, controlled trials t...
