In the last few years, many efforts have been devoted to investigating antibacterial activity of metal nanoparticles, especially against multidrug-resistant bacteria. Recently extensively drug-resistant (XDR) bacteria emerged and caused a global threat. The purpose this manuscript was synthesize nanostructured γ-Al2O3 as an agent some XDRs. results showed that Al2O3 mix rod spherical shapes in ...

Deoxyribose test has been widely used for determination of reactivities of various compounds for the hydroxyl radical. The test is based on the formation of hydroxyl radical by Fe2+ complex in the Fenton reaction. We propose a modification of the deoxyribose test to detect strong iron binding, inhibiting participation of Fe2+ in the Fenton reaction, on the basis of examination of concentration ...

OBJECTIVE Glucocorticoids are considered the main treatment option for chronic rhinosinusitis with nasal polyps (CRSwNP), but their effect rate ranges from 60.9% to 80%. Novel therapeutic means should be studied. The purpose of this study was to investigate the expression of Orai1 in nasal polyps (NPs) and the influence of intervention of Orai1 on NPs after in vitro treatment of 2-aminoethoxydi...

Nanoparticles (NPs) that combine biocompatibility and enhanced physical characteristics for biomedical applications are currently an area of intense scientific research. Hafnium oxide NPs innovative approach in the anticancer treatment by radiotherapy due to their low toxicity enhancement local dose tumor reducing total radiation patient. The combination this property with excellent magnetic hy...

Introduction. Non-ferrous smelters are one of the critical nanoscale cadmium particles sources in workplace and ambient air. Materials methods. The research was performed to evaluate subchronic toxicity oxide nanoparticles (CdO-NPs) white outbred rats. Male 3.5-month old rats received intraperitoneal injections CdO-NPs 3 times a week for six weeks (18 total) doses 0.25 mg/kg body mass. After en...

Both mammalian and bacterial ferritin undergo rapid reaction with small-molecule reductants, in the absence of Fe2+ chelators, to form ferritins with reduced (Fe2+) mineral cores. Large, low-potential reductants (flavoproteins and ferredoxins) similarly react anaerobically with both ferritin types to quantitatively produce Fe2+ in the ferritin cores. The oxidation of Fe2+ ferritin by large prot...

Identifying the metal ions that optimize charge transport and charge density in metal-organic frameworks is critical for systematic improvements in the electrical conductivity in these materials. In this work, we measure the electrical conductivity and activation energy for twenty different MOFs pertaining to four distinct structural families: M2(DOBDC)(DMF)2 (M = Mg2+, Mn2+, Fe2+, Co2+, Ni2+, ...
