Some macroglial cells of the O-2A lineage express glutamate receptor channels of the quisqualate/kainate type and take up extracellular cobalt when activated by glutamate agonists. These cells can be identified both in vitro and in situ following precipitation and intensification of the intracellular cobalt. We have used this technique to characterize these cells in the developing and adult rat...

The incorporation of cobalt into low molecular mass nitrile hydratase (L-NHase) of Rhodococcus rhodochrous J1 has been found to depend on the alpha-subunit exchange between cobalt-free L-NHase (apo-L-NHase lacking oxidized cysteine residues) and its cobalt-containing mediator (holo-NhlAE containing Cys-SO(2)(-) and Cys-SO(-) metal ligands), this novel mode of post-translational maturation havin...

Heparin is an injectable anticoagulant that prevents coagulation. There are presently high and low molecular heparins as well as synthetic pentasaccharide inhibitors. Given its ubiquitous use in sensitive medical states, there is a high concern for safety with this drug. Heparin can induce several distinct immune-mediated reactions. There are several options to consider when heparin allergy occ...

After more than a century since its birth, Quantum Theory still eludes our understanding. If asked to describe it, we have to resort to abstract and ad hoc principles about complex Hilbert spaces. How is it possible that a fundamental physical theory cannot be described using the ordinary language of Physics? Here we offer a contribution to the problem from the angle of Quantum Information, pro...

Late-preterm newborns accounted for 8.7% of all US births in 2009, while in Italy, according to Euro-Peristat Report 2010, rate of preterm live births between 32 and 36 weeks accounts for 6.4%: therefore late-preterm incidence is around 5% [1]. In the literature is reported that late preterm infants are at increased risk of neonatal mortality and morbidity, including feeding problems, hyperbili...

In this work, CoFe₂O₄@SiO₂@TiO₂ core-shell magnetic nanostructures have been prepared by coating of cobalt ferrite nanoparticles with the double SiO₂/TiO₂ layer using metallorganic precursors. The Transmission Electron Microscopy (TEM), Energy Dispersive X-Ray Analysis (EDX), Vibrational Sample Magnetometer (VSM) measurements and Raman spectroscopy results confirm the presence both of the silic...

Nanoparticles of rubidium cobalt hexacyanoferrate (RbjCok[Fe(CN)6]l · nH2O) were synthesized using different concentrations of polyvinylpyrrolidone (PVP) to produce four different batches of particles with characteristic diameters ranging from 3 to 13 nm. Upon illumination with white light at 5 K, the magnetization of these particles increases. The long-range ferrimagnetic ordering temperatures...

Cytotoxicity and cell growth inhibition studies were performed for five distinct cobalt(ll) [Co(2)(acac)tpmc](ClO(4))(3), [Co(2)(dibzac)tpmc](ClO(4))(3), [Co(2)(hfac)tpmc](CIO(4))(2), [Co(2)(tmhd)tpmc](CIO(4))(3) and [Co(2)(ox)tpmc](CIO(4))(2).3H(2)0 and five molybdenum(Vl) complexes, [MoO(2)(pipdtc)(2)], [MoO(2)(morphdtc)], [MoO(2)(timdtc)(2)], [MoO(2)(pzdtc)(2)] and [MoO(2)(N-Mepzdtc)(2)].
