A nanoemulsion (NE) is a surfactant-based, oil-in-water, nanoscale, high-energy emulsion with a mean droplet diameter of 400-600 nm. When mixed with antigen and applied nasally, a NE acts as a mucosal adjuvant and induces mucosal immune responses. One possible mechanism for the adjuvant effect of this material is that it augments antigen uptake and distribution to lymphoid tissues, where the im...

BACKGROUND Superparamagnetic iron oxide nanoparticles have been used in clinical applications as a diagnostic contrasting agent. Previous studies showed that iron oxide nanoparticles deposited in the liver and spleen after systemic administration. The present study investigated the effect of iron oxide nanoparticles on antigen-specific immune responses in mice sensitized with the T cell-depende...

in this study, undoped zno and doped with fe and mn nanostructures were synthesized by hydrothermal method. the morphology of nanostructures was characterized by scanning electron microscope. the electrochemical response of the carbon paste electrode modified with nanoparticles of zno and also zno doped with fe and mn toward levodopa (l-dopa) was studied. studies of cyclic voltammetry using pro...

This paper investigates the use of shop-floor ferrous scrap that contains iron ore as a raw material for purpose making steel products through an in situ carbothermic reduction. The technique powder metallurgy (PM) was used studying reduction followed by densification during sintering. Two sources oxide—ferrous grinding-sludge and ore—and three carbonaceous material—graphite, charcoal, carbon b...

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...

Fungal nitric oxide reductase (cytochrome P450 nor) is a heme-containing enzyme, in which the iron-porphyrin complex is an active site of the enzyme. This enzyme is involved in the fungal denitrification process, and catalyzes the reduction of NO to N2O. Its structural and functional characteristics were examined by enzymatic, kinetic, spectroscopic (optical absorption, ESR, resonance Raman, IR...

The extreme osmotic conditions prevailing in hypersaline environments result in decreasing metabolic diversity with increasing salinity. Various microbial metabolisms have been shown to occur even at high salinity, including photosynthesis as well as sulfate and nitrate reduction. However, information about anaerobic microbial iron metabolism in hypersaline environments is scarce. We studied th...
