introduction: iiron oxide nanoparticles (io np) have an increasing number of biomedical applications. to date, the potential cytotoxicity of these particles remains an issue of debate. little is known about the cellular interaction or toxic effects of io np on differentiation of stem cells. the aim of the present study was to investigate the possible toxic role of different doses of io np in di...

The most important component of steelmaking slags is the iron oxide since it serves as the oxidizing agent in refining reactions. The measurement of the iron oxide content is performed in the steelworks by taking a sample out of the liquid slag, cooling it and subsequently analysing it. The procedure takes some time. It would be highly desirable, therefore, to develop methods for rapid in situ ...

Background and Aim: Iron oxide nanoparticles are used in fields related to nanotechnology including ecology, magnetic storage, imaging and medicinal purposes. Iron nanoparticles produce reactive oxygen species (Ros). These materials are able to cross the placenta. The aim of this study was to investigate toxic effect of iron oxide nanoparticles on fetal lung in mice. <br ...

objective(s) previous studies have demonstrated that the nitric oxide (no) dependent death of murine peritoneal macrophages activated in vitro with ifn-g and lps is mediated through apoptosis. in the present study, we investigated the synergistic effect of lps, ifn-g and iron on no production and apoptosis. materials and methods after determination of iron cytotoxicity, the peritoneal macrophag...

objective(s): pseudomonas aeruginosa is a nosocomial pathogen resistant to most antimicrobial treatments. furthermore, it persists in adverse environments thereby forming biofilms on various surfaces. researchers have therefore focused on antibiofilm strategies using nanoparticles due to their unique physicochemical properties. superparamagnetic iron oxide nanoparticles (sionps) have recently s...

Computational studies have attracted the attention of researchers to understand the structural behavior of the molecules. These methods grade complex systems for novel properties with new predictions in areas of physics, chemistry and biology useful for conduct of experimental studies. Nanoparticles in present day technologies have become integral part in diverse areas of science mostly with me...

A highly bioactive bone-bonding Ti metal was obtained when Ti metal was simply heat-treated after a common acid treatment. This bone-bonding property was ascribed to the formation of apatite on the Ti metal in a body environment. The formation of apatite on the Ti metal was induced neither by its surface roughness nor by the rutile phase precipitated on its surface, but by its positively charge...
