objective: the aim of this study was to evaluate the effect of zinc and magnesium supplementation on glycemic control and serum insulin in type 2 diabetic patients. materials and methods: in this randomized clinical trial 70 diabetic patients who referred to yazd diabetes center were selected. subjects received 500 mg/day magnesium oxide or 100 mg/day zinc sulfate randomly for 8 weeks. at the s...

conclusions according to the results, cop is an efficient and rapid method for removing of toluene from aqueous solutions. results the analysis of variance (anova) of the toluene degradation by cop/mgo nanoparticles showed f-value of 19.53 for the quadratic model indicating that the prepared model is significant. the predicted result showed that maximum degradation of toluene (~99.99%) could be...

the present investigation attempted to develop the ceramic adsorbent media in order to remove the mercury from aqueous phase. two ceramics, akadama volcanic ash soil-ceramic (aceramic) and improved magnesium oxide impregnated akadama volcanic ash soil-ceramic (maceramic) were produced from raw akadama volcanic ash soil by heating process to determine the hg(ii) adsorption capacity. adsorption e...

Nanoparticles of iron oxide (crystalline and amorphous), silicon oxide and magnesium oxide were investigated for their propensity to nucleate ice over the temperature range 180–250 K, using the AIDA chamber in Karlsruhe, Germany. All samples were observed to initiate ice formation via the deposition mode at threshold ice super-saturations (RHithresh) ranging from 105% to 140% for temperatures b...

Dermal drug delivery is highly preferred by patients due to its several advantages. Protein therapeutics have attracted huge attention recently. Since dermal delivery of proteins encounter problems, in this investigation, zinc oxide nanoparticles and calcium phosphate nanoparticles were compared as enhancers for dermal permeation of albumin. Albumin was applied simultaneously with zinc oxide na...

Objective: The objective of this study was to investigate the antibacterial activities of combination of MgO and ZnO nanoparticles in the presence of heat against Escherichia coli and Staphylococcus aureus. Materials and Methods:Bacteria were grown on either agar or broth media followed by the addition of ZnO and MgO nanoparticles. Then the combined effect of ZnO and MgO nanoparticles was inves...

This work demonstrated the effect of functionalized magnesium oxide (MgO) nanoparticles with 3-(aminopropyl) triethoxysilane (APTES) as fillers on mechanical and thermal properties epoxy composite. The functionalization MgO (S-MgO) considerably improved interface between resin. composites revealed that addition their tensile strength, modulus elasticity, ductility when compared to neat epoxy. I...

the friction stir process (fsp) is a solid state process, which has been used to insert reinforcing particles into the structure of a material to create a composite with improved properties. magnesium is a light structural metal that is increasingly used in the aerospace and automobile industries. in this research, sic nanoparticles were added to az31 alloy using fsp in two overlaps of 100% and...
