We performed inhalation and intratracheal instillation studies of cerium dioxide (CeO2) nanoparticles in order to investigate their pulmonary toxicity, and observed pulmonary inflammation not only in the acute and but also in the chronic phases. In the intratracheal instillation study, F344 rats were exposed to 0.2 mg or 1 mg of CeO2 nanoparticles. Cell analysis and chemokines in bronchoalveola...
OBJECTIVE Cerium oxide (CeO2) nanoparticles have been shown to protect cells in culture from lethal stress, but no protection in vivo has been reported. Cardiac-specific expression of monocyte chemoattractant protein (MCP)-1 in mice causes ischemic cardiomyopathy associated with activation of endoplasmic reticulum (ER) stress. The aim of this study was to assess the effects of CeO2 nanoparticle...
Hemocompatible nanoparticles with reactive oxygen species (ROS) scavenging properties for titanium implant surface coatings may eliminate failure related to inflammation and bacterial invasion. Cerium (Ce) is a rare earth element, that belongs the lanthanide group. It exists in two oxidation states, Ce+3 Ce+4, which contribute antioxidant, catalytic, antibacterial, ROS-scavenging properties. Th...
In recent years, mesoporous bioactive glass nanoparticles (MBGNPs) have generated great attention in biomedical applications. this study, cerium and gallium doped MBGNPs were prepared by microemulsion assisted sol-gel method the binary SiO2-CaO system. with spheroidal pineal shaped morphology obtained. Nitrogen sorption analysis elucidated structure of synthesized high specific surface area. X-...
In this paper, the bismuth vanadate (BiVO4) nanoparticles were synthesized at 600 °C calcination temperature by co-precipitation method. To study the crystal structure, morphology, optical and photocatalytic properties of the samples, the X-ray diffraction analysis, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy and ult...
