We previously reported an endogenous, membrane-bound Cu oxidase with homology to ceruloplasmin in BeWo cells, a placental choriocarcinoma cell line. In this previous study, ceruloplasmin immunoreactivity was localized to the perinuclear region and non-brush-border membranes. Here, we show that azide-sensitive oxidase activity is enriched in the same fractions, correlating subcellular localizati...

abstract in order to study the effects of variety, water regime, zinc and cadmium levels on concentration, content and translocation of p, cu, fe and mn on rice, a factorial experiment was conducted consisting of four factors including: two varieties of rice (vandana and hashemi), two water regimes (flooded and nonflooded), three levels of zinc, and three of cadmium (0, 5 and 10 mg kg-1). the e...

The concentrations of zinc (Zn), iron (Fe) and copper (Cu) in both human milk and infant formula were determined using a new sample preparation method, by inductively coupled plasma - optical emission spectometry (ICP-OES) and flame atomic absorption spectrometry (FAAS). Human milk samples were diluted in ultrapure water. The infant formula of powder samples (suitable for an infant 1-6 months o...

AIM To assess the salivary levels of Copper (Cu), Zinc (Zn), Manganese (Mn) and Iron (Fe) obtained from children of different ethnic backgrounds in Shah Alam, Malaysia and investigate the possible relationships with caries. MATERIALS AND METHODS One hundred and twenty primary school children were included. They were divided into caries and caries-free groups. Unstimulated whole saliva was col...

Concentrations and bioconcentration potential of nine elements (Ca, Cu, Fe, K, Mg, Mn, Na, P, and Zn) in ten species of wild edible Boletus and the corresponding underlying soils were analyzed. The analyses were performed using inductively coupled plasma atomic emission spectrophotometer. Boletus showed relative abundant contents of P, K, Fe, Mg, Ca, and Na and less of Zn, Cu, and Mn. Caps comp...

Fe or Co based alloys with nanocrystalline microstructure show excellent permeability because the net magnetocrystalline anisotropy is significantly reduced when the grain size becomes smaller than the ferromagnetic exchange length. Fe-Si-B-Nb-Cu alloy is the pioneering nanocrystalline soft magnetic material invented by Yoshizawa et al. in 1988 [1]. Our previous works [2,3] reported evidence fo...

Broken-symmetry density functional theory (BS-DFT) calculations are assessed for redox energetics [Cu(SCH3)2]1-/0, [Cu(NCS)2]1-/0, [FeCl4]1-/0, and [Fe(SCH3)4]1-/0 against vertical detachment energies (VDE) from valence photoelectron spectroscopy (PES), as a prelude to studies of metalloprotein analogs. The M06 and B3LYP hybrid functionals give VDE that agree with the PES VDE for the Fe complex...

To provide the basic information about the release of heavy metals from the pyrite tailings of Huangjiagou pyrite mine, the pyrite tailings were investigated through a series of batch experiments under different initial pH of extractant, temperature, liquid-solid (LS) ratio, and soaking time conditions. Moreover, calcium carbonate was added in the pyrite tailings to determine the reduction effe...

buchitic glassy rocks appear within the skarn of contact metamorphic aureole of feshark intrusive complex situated 30 km northeast of isfahan. intrusive complex is a multistage intrusion . noritic gabbro is the first inttrusion which is invaded later on by a granitic melt. granitic melt has metasomatically altered the gabbro and as a consequence a suite of hybrid rocks like monzogabbro, monzodi...

A deep structural investigation predominantly by X-ray spectroscopic techniques is conducted on films of copper hexacyanoferrate (CuHCF) deposited under different conditions, aimed at establishing structure-properties relationships. We show that the potentiodynamic electrosynthesis of CuHCF on carbon-based surfaces produces a highly disordered material, with a variable amount of Prussian Blue (...
