Using the theory of non-negative intersections, duality of the Schubert varieties, and Pieri-type formula for a maximal orthogonal grassmannian, we get an upper bound for the canonical dimension cd(Spinn) of the spinor group Spinn. A lower bound is given by the canonical 2-dimension cd2(Spinn), computed in [8]. If n or n + 1 is a power of 2, no space is left between these two bounds; therefore ...

P1B-ATPases are decisive for metal accumulation phenotypes, but mechanisms of their regulation are only partially understood. Here, we studied the Cd/Zn transporting ATPases NcHMA3 and NcHMA4 from Noccaea caerulescens as well as AhHMA3 and AhHMA4 from Arabidopsis halleri. Protein biochemistry was analyzed on HMA4 purified from roots of N. caerulescens in active state. Metal titration of NcHMA4 ...

Cadmium (Cd) isotopes have great potential for understanding Cd geochemical cycling in soil and aquatic systems. Iron (oxyhydr)oxides can sequester via adsorption isomorphous substitution, but how these interactions affect isotope fractionation remains unknown. Here, we show that preferentially enriches lighter on iron (oxyhydr)oxide surfaces through equilibrium fractionation, with a similar ma...

In the dinuclear centrosymmetric title compound, [Cd2(C8H7O2)4(C6H6N2O)2(H2O)2], the Cd(II) ion is chelated by two carboxyl-ate groups from 4-methyl-benzoate anions, and is further coordinated by one nicotinamide and one water mol-ecule; a carboxyl-ate O atom from an adjacent 4-methyl-benzoate anion bridges to the Cd(II) ion, completing the irregular coordination sphere of the seven ligand atom...

Using the theory of non-negative intersections, duality of the Schubert varieties, and Pieri type formula for the varieties of maximal totally isotropic subspaces, we get an upper bound for canonical dimension cd(Spinn) of the spinor group Spinn. A lower bound is given by the canonical 2-dimension cd2(Spinn), computed in [10]. If n or n + 1 is a power of 2, no space is left between these two bo...

The chlorophyte microalga Chlorella sorokiniana was tested for the bioremediation of heavy metals pollution. It cultured with different concentrations Cu2+, Cd2+, As (III) and (V), showing a significant inhibition on its growth at 500 µM 250 750 AsO33- 5 mM AsO43- or higher. Moreover, consumption ammonium also studied, differences higher than 1 Cu2+ (III), (V). determination intracellular conce...

Cadmium pollution in the soil induces significant hazards to agricultural growth and public health. Therefore, new routes are needed develop low-cost amendments that can effectively stabilize cadmium improve fertility. This study introduces modified illite (MIT) with enhanced ability heavy metal Cd through mixing of calcium carbonate, silicate sulfate specific proportions by using well-known ca...

BACKGROUND Different abnormalities of T cell effector function distinguish Crohn's disease (CD) from ulcerative colitis (UC). Because cell cycling determines effector function, pathogenic events in CD and UC may depend on cell cycle changes unique to each condition. METHODS Cell cycle kinetics, cycle regulatory molecule expression, apoptosis, caspase and telomerase activity, and cellular expa...

in this work, a novel method is described for the preconcentration of pb2+, cd2+ and zn2+ ions in environmental samples using uniform silanized mesopor (lus-1) functionalized by ethylenediamine groups as a new extractant. the determination of ions is done by inductively coupled plasma optical emission spectrometry (icp-oes). the extraction time and efficiency, ph and amount of adsorbent, minimu...

The report by Claxton et all describes a close correlation between the type of aberrant mRNA transcripts for PML/RAR-a in 2 1 patients with acute promyelocytic leukemia (APL) and expression of CD2, a surface antigen of the Ig superfamily of cellular adhesion molecules that is generally associated with a T-lymphocyte phenotype.2 Since we have recently studied a number of patients with APL using ...
