The presence of 10 mM sodium molybdate has a profound effect on the physical behavior of glucocorticoid receptors submitted to ammonium sulfate precipitation or to DEAE-cellulose chromatography. Molybdate inhibits the inactivation of the unoccupied receptor and prevents the transformation of the steroid-bound receptor that occurs when rat liver cytosol is precipitated with ammonium sulfate. The...

Glucocorticoid receptors of rat kidney and liver were compared by physicochemical and immunochemical methods to investigate the role of proteolysis in the formation of corticosteroid binder IB. Kidney cytosol prepared in the presence of sodium molybdate contained receptor forms comparable to rat liver glucocorticoid receptor; [3H]triamcinolone acetonide-labeled receptors eluted from Sephacryl S...

Molybdenum is an essential element in plants and animals as a cofactor for enzymes. Molybdenum trioxide is used in metallurgical processes, in cosmetics as a pigment, and in contact lens solution, yet limited information is available on molybdenum genotoxicity. In the present study the micronucleus (MN) assay in human lymphocytes and mouse bone marrow and the dominant lethal assay in mice were ...

Estrogen receptors from rat uterus and human breast carcinoma were analyzed by diethylaminoethyl-cellulose chromatography. Cytosols which had been incubated for short periods of time demonstrated a single discrete elution peak, indicating a single ionic form, while cytosols incubated for longer periods of time generated a second ionic form of receptor. Addition of cations to cytosols also promo...

We present new magnetic heat capacity and neutron scattering results for two magnetically frustrated molybdate pyrochlores: S=1 oxide Lu_{2}Mo_{2}O_{7} and S=1/2 oxynitride Lu_{2}Mo_{2}O_{5}N_{2}. Lu_{2}Mo_{2}O_{7} undergoes a transition to an unconventional spin glass ground state at T_{f}∼16  K. However, the preparation of the corresponding oxynitride tunes the nature of the ground state from...

In order to reduce phosphorus pollution, the low passivation process on Q235 steel was studied. The electrochemical method used test corrosion resistance of sodium molybdate passivation. polarization curve shows that current sample passivated by is only 1/4 blank sample. Under scanning electron microscopy, film obtained treatment had lowest content and more uniform compact. XPS (X-ray photoelec...

Recently, much research has investigated nanocomposites and their properties for the development of energy storage systems. Supercapacitor performance is usually enhanced by use porous electrode structures, which produce a larger surface area reaction. In this work, biocompatible polymer starch medium was used to create nanostructure. Two powders, i.e., Nickel molybdate/reduced graphene oxide (...

The iron molybdate NaMgFe(MoO4)3 {sodium magnesium iron(III) tris-[molybdate(VI)]} has been synthesized by the flux method. This compound is isostructural with α-NaFe2(MoO4)3 and crystallizes in the triclinic space group P-1. Its structure is built up from [Mg,Fe]2O10 units of edge-sharing [Mg,Fe]O6 octa-hedra which are linked to each other through the common corners of [MoO4] tetra-hedra. The ...

The title compound, bis-[4,4'-(propane-1,3-di-yl)-dipiperidin-ium] β-octa-molybdate(VI), (C(13)H(28)N(2))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4)·2H(2)O and 4,4'-trimethyl-ene-dipiperidine (L). The structure of the title compound consists of β-octa-molybdate(VI) anion clusters and protonated [H(2)L](2+) cations. The octa-molybdate a...
