The increase in the cost of fertilizers and their low efficiency has led, through nanotechnology, to generation new innovative products that are sustainable improve productivity crops. Therefore, objective present study was evaluate efficacy a molybdenum nanofertilizer compared two conventional (chelate sodium molybdate) applied via foliar combined with soil fertilization NH4NO3 relation Nitrog...

This study compares the stabilizing effects of glycerol and sodium molybdate on the progesterone receptor in vitro. Trophoblastic tissue from day 12 embryos was homogenized in TD buffer (10 mM Tris, 1 mM dithiothreitol at pH 7.8, 4 degrees C) with 30% glycerol (v/v) (TDG-30%) and/or 10 mM sodium molybdate (TDG-30% + Mo and TD + Mo, respectively). Receptor was partially purified from cytosol by ...

1. [35S]sulphate was used to measure the apparent turnover of sulphate, sulphide and microbial-protein-S in the rumen contents of four sheep that were intraruminally infused with 10 g sodium sulphate/d alone, or together with 126 mg sodium molybdate (50 mg molybdenum). 2. Infusion of molybdate increased the concentration of sulphate in rumen fluid from 2.2 to 7.2 mug S/ml and decreased the rate...

A molybdenum-reducing bacterium from Antarctica has been isolated. The bacterium converts sodium molybdate or Mo⁶⁺ to molybdenum blue (Mo-blue). Electron donors such as glucose, sucrose, fructose, and lactose supported molybdate reduction. Ammonium sulphate was the best nitrogen source for molybdate reduction. Optimal conditions for molybdate reduction were between 30 and 50 mM molybdate, betwe...

The state of the electrochemical behaviour Al electrode in aqueous solutions containing Na2MoO4 + H3PO4 chitosan was investigated by methods currentless chronopotentiometry, chronoamperometry, optical and scanning electron microscopy. modification surface polymolybdate phosphate layers carried out a potentiostatic mode potentials range from ?1 to ?3 V polarization time (from 15 90 min). element...

sodium oxalate without SDS) by varying the concentration of the dye (0.03 or 0.12 mmol/L), sodium oxalate (0 or 2 mmol/L), and SDS (25 or 100 mg/L) in all combinations. For protein assays, we mixed 20 ␮L of sample, calibrator, or water (blank) with 1 mL of PRM reagent and measured the absorbance at 600 nm after 30 min against the blank. The effects of the aminoglycosides on the absorbance readi...

The simultaneous spectrophotometric determination of phosphate and silicate ions in river water was examined by using ion-exclusion chromatography and post-column derivatization. Phosphate and silicate ions were separated by the ion-exclusion column packed with a polymethacrylate-based weakly acidic cation-exchange resin in the H(+)-form (TSKgel Super IC-A/C) by using ultra pure water as an elu...

The title compound, bis-[2,2'-dimethyl-3,3'-(butane-1,4-di-yl)diimidazol-1-ium] β-octa-molybdate(VI), (C(12)H(20)N(4))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4) and 1,4-bis-(2-methyl-1H-imidazol-1-yl)butane (hereafter L). The structure of the title compound consists of the β-octa-molybdate anions having a center of symmetry, and proto...

Forty crossbred wether lambs, 44 kg initial body weight, were used to study relative bioavailability of Mo in supplemental Mo sources and their effects on body Cu storage. The basal maize-soya-bean meal-cottonseed hulls diet contained 11.5 mg kgÿ1 Cu, 1.1 mg kgÿ1 Mo and 2.1 g kgÿ1 S (DM basis) and was supplemented with 0, 15, 30, or 45 mg kgÿ1 (as-fed basis) added Mo as reagent grade sodium mol...

With a recently developed method we detected rapid and sequential reorganization of vitamin D receptors (VDR), including their temporary association with fibers, and we showed that calcitriol induces cGMP accumulation around reorganizing VDRs. In this report we first identified the VDR-associated fibers as microtubules: they show immunoreactivity with tubulin antisera and were sensitive to tubu...
