In the crystal structure of the title compound, [Cu(C(18)H(15)As)(4)]PF(6), the Cu atom is coordinated by four As atoms of triphenyl-arsine ligands in a tetra-hedral geometry. The complex cation is located on a crystallographic threefold axis. Both PF(6) (-) anions are located on special positions of site symmetry . The Cu-As bond of the independent arsine ligand is shorter than the Cu-As bonds...

The title compound, [Cu(C(7)H(5)O(2))(C(18)H(12)F(3)P)(2)], a copper(I) tris-(4-fluoro-phen-yl)phosphine tropolonate derivative, is the first tropolonate complex with fluorinated aryl-phosphine ligands. The Cu(I) atom has a distorted tetra-hedral coordination; the most important geometrical parameters of the mol-ecule are: Cu-P = 2.2377 (10) and 2.2335 (15) Å, Cu-O = 2.084 (2) and 2.082 (2) Å, ...

BACKGROUND Chronic urticaria (CU) can be provoked by a wide variety of causes. Some studies suggest contact sensitization may play a role in the disease. OBJECTIVE To investigate the incidence and distribution characteristics of allergic contact sensitization in central Chinese subjects with CU, and assess contact allergen avoidance measures in managing CU. METHODS Patch tests were performe...

In the title complex, [Cu(C(15)H(11)BrN(2)O(3))(C(5)H(5)N)], the central Cu(II) atom is in a square-planar CuN(2)O(2) coordination environment formed by the tridentate hydrazone and the monodentate pyridine ligands with N atoms in a trans-arrangement about the Cu(II) atom.

The present study investigated trajectories of Callous Unemotional (CU) traits in youth with Disruptive Behavior Disorder diagnosis followed-up from childhood to adolescence, to explore possible predictors of these trajectories, and to individuate adolescent clinical outcomes. A sample of 59 Italian referred children with Disruptive Behavior Disorder (53 boys and 6 girls, 21 with Conduct Disord...

This paper discusses the application of Love mode propagating on Cu-grating/rotated YX-LiNbO3-substrate structure to the development of ultra-wideband and low-loss RF SAW filters. Theoretical analysis suggested that high performance resonators with very small capacitance ratio would be realised using Cu gratings of the thickness of several percent of wavelength. It was also suggested that in pa...

Low-dimensional copper interconnects are prone to void formation which takes place during the Cu-filling of narrow interconnect lines. These voids increase the electrical resistance of the interconnects which in turn results in an increase of the RC delay of the integrated circuit. Therefore, a fast and non-destructive method is needed, which will allow the detection of the voids in copper inte...

Metals in soils amended with sewage sludge are typically less available compared with those in soils spiked with soluble metal salts. However, it is unclear if this difference remains in the long term. A survey of copper (Cu) availability was made in soils amended with sewage sludge, manure, and compost, collectively named organic amendments. Paired sets of amended and control soils were collec...

The dinuclear molecule of the title compound, [Cu(2)(C(2)O(4))(C(18)H(15)P)(4)]·2CH(2)Cl(2), lies across an inversion center with a strictly planar bridging oxalate ligand coordinating two Cu(I) ions via two pairs of O atoms. Two triphenyl-phosphine ligands also coordinate each symmetry-related Cu(I) ion, resulting in a distorted tetra-hedral geometry [O-Cu-O = 80.57 (5)° and P-Cu-P = 125.72 (2...

We have previously shown that chelated copper stimulates the release of luteinizing hormone-releasing hormone (LHRH) from isolated hypothalamic granules. In this study, we wished to ascertain if chelated copper acts on hypothalamic neurons to stimulate LHRH release and, if so, what is the ligand specificity of this interaction. An in vitro system of explants of the median eminence area (MEA) wa...
