Because sodium molybdate stabilizes steroid receptors, this compound has been included in the homogenizing medium in order to maximize the recovery of measurable steroid receptors in normal and neoplastic tissues. This study demonstrates that sodium molybdate extracts additional androgen receptors from prostatic nuclei in a concentration-dependent manner. Nuclei previously washed with Triton X-...

Different concentrations of ammonium molybdate (10(-7) to 10(-4)M) affected the levels of metabolites in the source and sink organs of the seedlings of C. melo and C. vulgaris and data were recorded at 7, 14 and 21 days after treatment (DAT) of molybdenum (Mo). Reducing and non reducing sugars declined with an increase in concentration of ammonium molybdate from 10(-7) to 10(-4) M. Soluble prot...

The range of inorganic acid normalities for maximum color formation of the phosphomolybdenum-blue complex (under heating) increases by elevating the ammonium molybdate concentra­ tion, and at a ratio of molybdate molarity/acid normality equal to 10, there is maximum color development at any acid normality in the range 1—4 n with either HC104 or H2S04 (or their mixtures). On the basis of these f...

A 1,10-phenanthroline (phen) chelated molybdenum(VI) citrate, [(MoO2)2O(H2cit)(phen)(H2O)2] x H2O (1) (H4cit = citric acid), is isolated from the reaction of citric acid, ammonium molybdate and phen in acidic media (pH 0.5-1.0). A citrato oxomolybdenum(V) complex, [(MoO)2O(H2cit)2(bpy)2] x 4H2O (2), is synthesized by the reduction of citrato molybdate with hydrazine hydrochloride in the presenc...

The LUMINEU program aims at performing a pilot experiment on neutrinoless double beta decay of Mo using radiopure ZnMoO4 crystals operated as scintillating bolometers. Growth of high quality radiopure crystals is a complex task, since there are no commercially available molybdenum compounds with the required levels of purity and radioactive contamination. This paper discusses approaches to puri...

I . The oral administration of sodium molybdate caused a rapid rise of molybdenum in the milk of cows and goats fed on a low-molybdenum diet, but did not affect the xanthine oxidase activities of the milk of either species. 2. In the milks of cows not dosed with sodium molybdate, the regression of the xanthine oxidase activity ( y ) on the molybdenum content (x) was found to be (r = +0.9386; P ...

The aim of this in vitro study was to examine the secretion activity (progesterone, 17beta-estradiol and insulin-like growth factor-I) of rat ovarian fragments after molybdenum (Mo) addition. Rat ovarian fragments were incubated with ammonium molybdate (NH(4))(6)Mo(7)O(24).4H(2)O at the doses 90, 170, 330 and 500 microg.ml(-1) for 24 h and compared with control group without Mo addition. Releas...

Glutathione (GSH) production during wine fermentation is a desirable trait as it can limit must and wine oxidation and protect various aromatic compounds. UMCC 2581 is a Saccharomyces cerevisiae wine strain with enhanced GSH content at the end of wine fermentation. This strain was previously derived by selection for molybdate resistance following a sexual cycle of UMCC 855 using an evolution-ba...

We have investigated the physiochemical characteristics of trypsin-treated, molybdate-stabilized glucocorticoid-receptor complexes from rat liver in the presence of 10 mM sodium molybdate by high performance ion-exchange chromatography, high performance size-exclusion chromatography, and sedimentation analysis. Trypsin treatment was performed under conditions previously reported to degrade the ...

The self-assembly of molybdate building units in the presence of Fe(II) and V(IV) produces the first mixed-spin heterometal keplerate-type clusters displaying ferrimagnetic interactions.
