introduction: nanoparticles are being increasingly applied in dentistry due to their antimicrobial and mechanical properties. this in vitro study aimed to assess and compare the cytotoxicity of four metal oxide nanoparticles (tio 2 , sio 2 , zno, and al 2 o 3 ) on human dental pulp stem cells. methods and materials: four suspension with different concentrations (25, 50, 75, 100 µg/ml) of each n...
Background: Direct observation of cell behavior is involved in vivo and ex vivo study. The aim of this study was to investigate the effect of magnesium oxide nanoparticles on isolated rat lung alveolar pneumocyte cells, after severance and determine the amount of no-effect nanoparticles. Methods: In this lab trial study, in addition to determine the viability of isolated cells with Trepan blue...
Auger and X-ray photoelectron spectroscopies have been used to study the surface composition of MnxCo1−xO (0 ≤ x ≤ 1) solid solutions. The polycrystalline materials, which are bulk homogeneous, present clear signs of deviation in surface composition at xbulk ≈ 0.2–0.4 to become surface-enriched in manganese at the expense of the cobalt. Whether on stoichiometric or cobalt-depleted surfaces, cob...
Superparamagnetic Fe(3)O(4) nanoparticles were successfully grafted onto the manganese oxide OMS-2 nanowires, and the synthesized material exhibits excellent magnetic separation and adsorption properties.
In the literature, few studies detailed morphometric parameters of the inferior olivary complex, and mainly applying biased methods based on counting in a two-dimensional plane. In the present work, the unbiased quantitative method of the optic disector was applied in order to analyse neuronal densities, nuclear volumes and total neuron numbers of the principal (PION), medial (MION) and dorsal ...
In this paper, graphene oxide decorated with cerium oxide (CeO2) nanoparticles was prepared and used as anticorrosive pigments in epoxy nanocomposite coatings. The synthesized nanoparticle was characterized by FTIR, XRD, SEM, and EDX analyses. Graphene oxide decorated with CeO2 nanoparticles was dispersed in epoxy resin by sonication. The optimum nanoparticle content of th...
Nanostructured microspheres of manganese oxide have been prepared by the solution processing ofmanganese(II) salts using 1,4,7,10-tetraazacyclododecane and utilizing a crystalline intermediate stage.
Temelieh area is located about 20 Km northwest of Selseleh (Lorestan Province). Geologically, the area is a small part of the Harsin radiolarite complex. Petrography consists of radiolarite, peridotite, gabbro, plate dikes, basalt and andesite, limestone, and marble. Manganese mineralization occurs as vein-veinlet and is mainly formed in faults, joints, and fractures that crosscut in radiolarit...
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...
