A geochemical and speciation study of As, Fe, Mn, Zn, and Cu was performed using sequential extraction and statistical approaches in the core sediments taken at two locations-Rigni Chhapra and Chaube Chhapra-of the central Gangetic basin (India). A gradual increase in the grain size (varying from clay to coarse sands) was observed in both the core profiles up to 30.5 m depth. The concentrations...

Abstract manganese lipoxygenase (Mn-LO) oxygenates 18:3n-3 and 18:2n-6 to bis-allylic 11S-hydroperoxy fatty acids, which are converted to 13R-hydroperoxy fatty acids. Other unsaturated C(16)-C(22) fatty acids, except 17:3n-3, are poor substrates, possibly because of ineffective enzyme activation (Mn(II)-->Mn(III)) by the produced hydroperoxides. Our aim was to determine whether unsaturated C(16...

The probiotics are being used as ecofriendly and bioremediation tools for developing sustainability to aquaculture. present study was conducted explore the practical capability of using dietary lactic acid bacteria (Pediococcus acidilactici) see how its dose variation affected water quality, growth performance, survival rate, body composition, blood biochemical parameters, intestinal histology ...

Acute myeloid leukemia (AML) is a clonal disorder of the hematopoietic stem cell, typical of the elderly, with a median age of over 60 years at diagnosis. In AML, older age is one of the strongest independent adverse prognostic factor, associated with decreased complete response rate, worse disease-free and overall survival, with highest rates of treatment related mortality, resistant disease a...

The magnetic properties of spinel nanoparticles are determined by crystal chemistry issues such as cation distribution and oxidation states. The cation distribution and oxidation state of Mn-Fe spinel nanoparticles have been systematically studied at various temperatures by using neutron diffraction and electron energy loss spectroscopy, respectively. The Mn-Fe spinel nanoparticles prepared by ...

BACKGROUND A major goal in influenza vaccine development is induction of serological memory and cellular responses to confer long-term protection and limit virus spread after infection. Here, we investigate induction of long-lived immunity against the 2009 H1N1 virus after skin vaccination. METHODS BALB/c mice received a single dose of 5 μg inactivated A/California/04/09 virus via coated meta...

Adam J. Hauser and Fengyuan Yang Department of Physics, The Ohio State University, 191 Woodruff Avenue, Columbus, Ohio 43210, USA (Dated: August 22, 2010) Abstract Ferromagnetic δ-phase manganese gallium layers with Mn/(Mn + Ga) = 60% have been successfully grown on ScN(001) by molecular beam epitaxy, expanding possibilities for ferromagnetic layers on nitride semiconductors. The in-plane epita...

Photocatalytic enantioselective epoxidation of terminal olefins using a mononuclear non-heme chiral manganese catalyst, [(R,R-BQCN)MnII]2+, and water as an oxygen source yields epoxides with relatively high enantioselectivities (e.g., up to 60% enantiomeric excess). A synthetic mononuclear non-heme chiral Mn(IV)-oxo complex, [(R,R-BQCN)MnIV(O)]2+, affords similar enantioselectivities in the epo...
