In this study we developed, characterized and validated in vitro a functional superparagmagnetic iron-oxide based magnetic resonance contrast agent by conjugating a commercially available iron oxide nanoparticle, Molday ION Rhodamine-B Carboxyl (MIRB), with a deimmunized mouse monoclonal antibody (muJ591) targeting prostate-specific membrane antigen (PSMA). This functional contrast agent is int...

The iron oxide nanoparticles have been synthesized in co-precipitation method using aqueous solution of ferric and ferrous ions with sodium salt. The synthesis of iron-oxide nanoparticles were validated by UV-Visible spectroscopy which showed higher peak at 370 nm as valid standard reference. An average size of iron oxide nanoparticle found by diffraction light scattering (DLS) particle size an...

Oxidative stress has been implicated as an important factor in induction of many disorders such as nephropathy and cancer. Iron by producing hydroxyl radical can cause this kind of stress. On the other hand nitric oxide (NO) when its concentration is high results in oxidative stress. Iron and NO have some interactions in each other function but there is no total agreement on this. For example i...

Iron oxide impregnated casein nanoparticles (IOICNPs) were prepared by in-situ precipitation of iron oxide within the casein matrix. The resulting iron oxide impregnated casein nanoparticles (IOICNPs) were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Vibrating sample magnet...

Introduction: In order to achieve sustainable development in mining, waste management is an essential requirement. The current study aimed to examine industrial solid waste produced in Golgohar Mining and Industrial Company, which is a well-known iron ore extraction and processing complex. Materials and Methods: This cross-sectional study was conducted in two phases from March, 2016 through Ma...

BACKGROUND Macrophages have been identified as a major contributor to plaque development and destabilization in atherosclerosis. The aim of this study was to noninvasively assess uptake of citrate coated very small iron oxide particles at different stages of plaque development in the brachiocephalic artery of apoE(-/-) mice. Susceptibility gradient mapping (SGM) was applied to generate positive...

microwave energy has potential for the efficient heating of minerals. minerals or materials, which couple to microwave energy are called dielectrics and many valuable minerals are found to be dielectric. the mineral ilmenite is one which shows good dielectric heating characteristics. in this paper, the effect of microwave heat energy on the partial reduction of oxidized ilmenite oxidized in ...

A solar fuels generation research program is focused on hydrogen production by means of reactive metal water splitting in a cyclic iron-based redox process. Iron-based oxides are explored as an intermediary reactive material to dissociate water molecules at significantly reduced thermal energies. With a goal of studying the resulting oxide chemistry and morphology, chemical assistance via CO is...

The effect of Cu on the reduction behavior and surface properties of supported and unsupported Fe-based Fischer-Tropsch synthesis (FTS) catalysts was investigated using in situ X-ray photoelectron spectroscopy (XPS) and in situ X-ray absorption spectroscopy (XAS) in combination with ex situ bulk characterization. During exposure to 0.4 mbar CO-H(2) above 180 degrees C, the reduction of CuO to C...
