Recently, there has been a great deal of interest in the use of the medicinal plants with high antioxidant compounds for curing liver injuries induced by hepatoxcitic agents. This study was to assess the protective effect of Carum carvi L. essential oil (E.O) on the hepatoxitic rats induced by overdose of iron oxide nanoparticles (NPs). The rats were distributed to 4 groups. In negative control...

The Stober process is frequently used to prepare silica-coated iron oxide nanoparticles. This is usually achieved by seeding a reaction mixture consisting of water, ethanol and a catalyst with iron oxide particles and adding a silica precursor. The hydrolysis and condensation of precursor monomers results in the deposition of a silica layer on iron oxide particles. However, this process is acco...

sorkheh-dizaj apatite-iron oxide deposit is located 32 km southeast of zanjan. the area is situated within the tarom subzone of western alborz-azarbaijan structural zone. the oldest units at the sorkheh-dizaj area are eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciate tuff and lapilli tuff which intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton o...

Laser-evaporated iron was deposited onto solid oxygen at 20 K to produce stratified samples consisting of Fe and 02 layers. The Mossbauer spectra of these samples were acquired in order too investigate their oxidation states and chemical properties. The reaction produced the trivalent iron oxide particles whose size varied depending on the amount of Fe atoms deposited on the solid oxygen. Sampl...

BACKGROUND It was recently reported that iron oxide nanoparticles attenuated antigen-specific humoral responses and T cell cytokine expression in ovalbumin-sensitized mice. It is presently unclear whether iron oxide nanoparticles influence T helper 1 cell-mediated immunity. The present study aimed to investigate the effect of iron oxide nanoparticles on delayed-type hypersensitivity (DTH), whos...

The relaxation rates of iron-oxide nanoparticles compartmentalized within cells were studied and found to satisfy predictions of the static dephasing (SD) regime theory. THP-1 cells in cell culture were loaded using two different iron-oxide nanoparticles (superparamagnetic iron-oxide (SPIO) and ultrasmall SPIO (USPIO)) with four different iron concentrations (0.05, 0.1, 0.2, and 0.3 mg/ml) and ...

in this study, a mixed matrix polyethersulfone/iron-nickel oxide nanoparticle nanofiltration membrane was prepared by the solution casting technique. polyvinylpyrrolidone was also used as a membrane pore former in membrane fabrication. the effect of iron-nickel oxide nanoparticles concentration in the casting solution on the membrane structure and performance was investigated. scanning optical ...

Zinc and iron nano-oxides (100 ppb) were promoted the hypericin and hyperforin production in Hypericum perforatum cell suspension culture. High performance liquid chromatography method was used for detectection and identification of hypericin and hyperforin in H. perfuratum cell suspension cultures elicited with different concentrations of zinc and iron nano-oxide (0, 50, 100 and 150 ppb) after...
