In this work, at first, nano ZrO2 and Fe3O4/ZrO2 nanocomposite were prepared by sol-gel and co-precipitation methods, respectively. Then, Ag nanoparticles (Ag NPs) were mixed with themin environmentally friendly and mild conditions using C. cyanus flower extract as a reducing and stabilizing agent. The synthesized nanocomposites were characte...

In the present work, we demonstrate a facile way to study the biosynthesis of silver nanoparticles (Ag-NPs) with strong bactericidal properties using an aqueous extract of Scrophularia striata Boiss. The bio-reduction of Ag+ ions resulted in FCC cubic structures of Ag-NPs with spherical shapes of about 16 nm. As a main aim of the present work, the antibacterial activity of the bio-synthesized A...

Seyed Mohammad Ali Shariatzadeh & Zahra Alizadeh Department of Biology, Faculty of Sciences, Arak University, Arak, Iran Correspondent author: Seyed Mohammad Ali Shariatzadeh, [email protected] Abstract. Silver nanoparticles (Ag NPs) can affect female fertility because they can cause toxicity in the ovaries. The aim of this study is to see if Spirulina platensis (SP) can protect m...

aflatoxin m1 (afm1) is a hydroxylated metabolite of the carcinogen aflatoxin b1 (afb1), and may be found in the milk of lactating animals that have ingested feedstuffs contaminated with afb1 between jun 2010 and march 2011, 149 samples of pasteurized (n=90) and uht (n=59) milk were collected from supermarkets in the cities of shiraz, khuzestan and yazed, iran. all samples were analyzed for afm1...

We consider of the antimicrobial activity on the Ag nanoparticles(Ag NPs) aqueous solutions, which was prepared using a stabilizer, such as poly(N vinyl 2 pyrrolidone PVP , for Staphylococcus aureus) S aureus and Escherichia coli E coli by measuring the minimum inhibitory concentration MIC . Antimicrobial effect of Ag NPs for S aureus and E coli was investigated using disk diffusion method Also...

Macrophage activation is the main immunological process occurring during the development of several diseases, and the heterogeneity of macrophage activation or differentiation has been suggested to be involved in disease progression. In the present study, we attempted to identify molecules specifically expressed on human classically activated macrophages (M1) to investigate the significance of ...
