background and aims: although metal and metal oxide nanoparticles are used in different medical applications, they may have considerable toxicity on various cells, such as myocytes. therefore, this study aimed to evaluate the toxicity of the naked and serum-treated silver nanoparticles (ag nps) and magnesium oxide nanoparticles (mgo nps) on the cardiomyocytes. materials and methods: cardiomyocy...

introduction: our previous study has showed that chronic administration of magnesium oxide nanoparticles (mgo np) can reduce anxiety in adult male rat. in this study the effects of mgo np on anxiety induced by morphine withdrawal were investigated in adult male mice. methods: adult male nmri mice (weighing 27 ± 3 g) divided into groups: control, receiving intraperitoneal (i.p.) injection of mgo...

a facile and simple method was proposed to control the size and shape of the mgo nano structures with high surface area in the presence of efficient and cheap templates like peg 200, peg 600, peg 4000 and sorbitol at low temperature within a little time. nano rods and nanoparticles have been achieved by applying these templates and altering other growth parameters. the products were characteriz...

Undoped Zinc oxide (ZnO) nanoparticles as well as ZnO nanoparticles doped with Magnesium (Mg) were synthesized by wet chemical precipitation method using Zinc acetate and Magnesium acetate in Ethylene glycol and distilled water medium. The prepared nanoparticles were characterized with X-ray diffraction (XRD). The XRD patterns show the pattern of typical ZnO nanoparticles and correspond with st...

objective(s): the objective of this study was to investigate the antibacterial activities of magnesium oxide nanoparticles (mgo np) alone or in combination with other antimicrobials (nisin and heat) against escherichia coli and staphylococcus aureus in milk.materials and methods: first, the combined effect of nisin and mgo nanoparticles was investigated in milk. then the combined effect of nisi...

Background: Magnesium oxide nanoparticles are characterized with a wide variety of applications and are mass-produced throughout the world. However, questions remain regarding their safety. There has been paucity of toxicology research on their side effects, especially under in vivo conditions. Objectives: The present paper aims at evaluating the...

Metal oxide nanomaterials are important and excellent materials, because of its special properties like chemical stability, high photo catalytic activity, high electric permittivity, non-toxic nature. So it is used in various applications like optical, electrical, electronic, antiseptic, antibacterial, environmental, semi conductors and catalytic devices. Present work focused on to synthesis of...

The antifungal activity of zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles prepared by bio-safe method was evaluated for Alternaria alternate, Fusarium oxysporum, Rhizopus stolonifer and Mucor plumbeus. It was observed from the study that all the nanoparticles at different concentrations brought about significant inhibition in the germination of spores of Alternaria alternata, Fusarium...

Magnesium oxide nanoparticles were synthesized using Arabic gum as a biotemplate andmagnesium nitrate as the magnesium source by the sol-gel method. This method has manyadvantages such as nontoxic, economic viability, ease to scale up, less time consuming andenvironmental friendly approach for the synthesis of MgO nanoparticles without using anyorganic chemicals. Nanoparticles were characterize...
