Under some conditions, the use of high-sulphur fertilisers has been thought to be associated with an increase in the incidence of copper deficiency among ruminants grazing the fertilised pastures or fed treated herbage. In this study 35 Romney lambs grazing ryegrass–white clover pasture of low molybdenum content (<0.5 mg Mo/kg DM) received dietary supplements of elemental S and Cu 3 times weekl...

Physicochemical studies of the human serum albuminCu(II)-L-histidine (HSA-Cu(II)-L-His) ternary complex at pH 7.5 indicate several interesting features. 1. The dissociation constants of the HSA-Cu(II)-L-His ternary complex and the HSA-Cu(I1) binary complex are 1.38 X 1O-22 and 6.61 x lOen, respectively. 2. The absorption spectrum of the ternary complex system has characteristics similar to thos...

Clinical isolates of meticillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumoniae, Pseudomonas aeruginosa, Acinetobacter baumannii, Candida albicans and Mycobacterium tuberculosis (MTB) were tested against copper (Cu) and its alloys. Stainless steel and polyvinylchloride (PVC) were used as controls. The amount of Cu required to inhibit test isolates at room temperature (24 degrees C...

Natural Cu target was irradiated with proton beam in the energy range of 15 to 30 MeV at a beam current of 100 μA for 15 min. In this irradiation radioisotope of 62Zn was produced as a generator and then decayed to Cu radioisotope. The Cu is emitting β+ and known as PET radioisotope. Excitation function of Cu via Cu (p, 2n) Zn, Cu and Cu (d, 3n) Zn reactions were calculated using Alice and Taly...

None were fatal, and all occurred platelet count in the course of chronic in the group with counts over a 1 x 1 0’/cu granulocytic leukemia was studied in a mm. The occurrence of thrombocytosis as group of 111 previously untreated paa new observation in the face of previous tients, whose entire course was evaluated normal counts (15 patients) wa...

New dental precious metal alloys for resin bonding without alloy surface modification were developed by adding base metals (In, Zn, or Sn). Before this, binary alloys of Au, Ag, Cu, or Pd containing In, Zn, or Sn were studied for water durability and bonding strength with 4-META resin. The adhesion ability of the binary alloys was improved by adding In equivalent to 15% of Au content, Zn equiva...

In the title compound, [Cu(C(13)H(20)N(2)O(2))(2)](ClO(4))(2), the Cu(II) atom in the complex dication is chelated by two phenolate O atoms and two imine N atoms from two zwitterionic 2-[2-(isopropyl-ammonio)ethyl-imino-meth-yl]-5-methoxy-phenolate ligands, forming a distorted square-planar geometry. One of the perchlorate anions is disordered over two sites with occupancies of 0.611 (15) and 0...

Single crystals of RMg 2 Cu 9 (R = Y, Ce-Nd, Gd-Dy, Yb) were grown using a high-temperature solution growth technique and were characterized by measurements of room-temperature x-ray diffraction, temperature-dependent specific heat, and temperature-and field-dependent resistivity and anisotropic magnetization. YMg 2 Cu 9 is a non-local-moment-bearing metal with an electronic specific heat coeff...

The title complex, [Cu(3)WBrOS(3)(C(18)H(15)P)(3)], a neutral heavily distorted cubane-like W/S/Cu cluster, was self-assembled from ammonium trithio-tungstate(VI), cuprous bromide and triphenyl-phosphane in N,N-dimethyl-formamide. The average Cu-Br, Cu-S and W-μ(3)-S bond lengths are 2.731 (2), 2.318 (2) and 2.256 (2) Å, respectively, in the distorted cubane-like skeleton. The W atom exhibits t...
