Neptunium complexes in the formal oxidation states II, III, and IV supported by cyclopentadienyl ligands are explored, and significant differences between Np and U highlighted as a result. A series of neptunium(III) cyclopentadienyl (Cp) complexes [Np(Cp)3], its bis-acetonitrile adduct [Np(Cp)3(NCMe)2], and its KCp adduct K[Np(Cp)4] and [Np(Cp0)3] (Cp0 1⁄4 C5H4SiMe3) have been made and characte...
Background: Nepeta dschuparensis Bornm (NP) is used as a medicinal herb in Iran. In traditional medicine, this herb is extensively employed for curing ailments such as cardiovascular diseases. NP has antioxidant and anti-inflammatory properties. This project examined the effects of the NP extract on cyclooxygenase-2 (COX-2) and interleukin-1β (IL-1β) protein levels and its efficacy in neuroprot...
3-Nitropropionic acid (3-NP) is an irreversible inhibitor of complex II in the mitochondria. 3-NP toxicity has gained acceptance as an animal model of Huntington's disease (HD). In the present study, we confirmed that rats injected with 3-NP (20 mg/kg, i.p., daily for 4 days) exhibit increased oxidative stress in both striatum and cortical synaptosomes as well as lesions in the striatum. Synapt...
p-nonylphenol (p-np) as a non ionic surfactant is used in many industries such as pesticides, cosmetics,detergents and so on. our previous study showed that the p-np causes reduction in viability of the rats bonemarrow mesenchymal stem cells (mscs). the aim of the present study was to investigate the mechanism of the cell death due to p-np exposure. the cells, after 3rd passage were treated wit...
A series of aluminum complexes supported by o-phenylene-derived amido phosphine ligands, N-(2-diphenylphosphinophenyl)-2,6-dimethylanilide ([Me-NP]-) and N-(2-diphenylphosphinophenyl)-2,6-diisopropylanilide ([iPr-NP]-), have been prepared. The reactions of trialkylaluminum with H[Me-NP] and H[iPr-NP], respectively, in refluxing toluene produced the corresponding dialkyl complexes [Me-NP]AlR(2) ...
INTRODUCTION The accelerated biodegradation of 3-nitrophenol (3-NP) in the rhizosphere of giant duckweed (Spirodela polyrrhiza) was investigated. MATERIALS AND METHODS Biodegradation of 3-nitrophenol in the rhizosphere of a floating aquatic plant, S. polyrrhiza, was investigated by using three river water samples supplemented with 10 mg l(-1) of 3-NP. Isolation and enrichment culture of 3-NP-...
The reaction of Np(V) chloride with molten boric acid results in the disproportionation of Np(V) into Np(IV) and Np(VI), and the crystallization of K(2)[(NpO(2))(3)B(10)O(16)(OH)(2)(NO(3))(2)]. UV-vis-NIR spectroscopy demonstrates that in addition to the Np(VI) and Np(V) found in the crystal structure, Np(IV) is also present.
