We have shown that copper amplifies prostaglandin E2 (PGE2) stimulation of luteinizing hormone-releasing hormone (LH-RH) from explants of the median eminence area (MEA) and that this process is calcium-dependent. Since a Ca-cAMP pathway has been implicated in PGE2 action on the LH-RH neuron, in this study we wished to ascertain if copper exerts its effect on the PGE2 receptor or on a postrecept...

A highly luminescent freestanding film composed of the quantum cluster, Au(15), was prepared. We studied the utility of the material for specific metal ion detection. The sensitivity of the red emission of the cluster in the composite to Cu(2+) has been used to make a freestanding metal ion sensor, similar to pH paper. The luminescence of the film was stable when exposed to several other metal ...

In the title complex, [Cu(C(18)H(14)NO)(2)], the Cu(II) ion lies on a crystallographic inversion centre and is bonded to the O- and N-donor atoms of the two bidentate chelate 1-[(o-tol-yl)imino-meth-yl]-2-naphtho-late ligands in a trans arrangement. The distorted square-planar geometry about Cu(II) has normal dimensions, with Cu-O = 1.8881 (15) Å and Cu-N = 1.9804 (17) Å.

The title compound, {[Cu(2)I(2)(C(12)H(8)N(6))(C(18)H(15)P)(2)]·2CH(3)CN}(n), contains centrosymmetric dinuclear Cu(2)I(2)(PPh(3))(2) units bridged by 3,6-bis-(4-pyrid-yl)-1,2,4,5-tetra-zine ligands lying also across crystallographic inversion centers, giving a chain structure in the ab plane. The distorted tetra-hedral Cu(I) atoms in the dinuclear unit are coordinated by two bridging iodide an...

Soret band lifetimes of the free-base tetraphenylporphine (H(2)TPP) and Cu(ii) tetraphenylporphine (Cu(II)TPP) at 408 nm have been directly measured with femtosecond (fs) resolution using the fluorescence-upconversion technique for the first time, giving tau = 68 +/- 15 and 63 +/- 15 fs, respectively, in benzene solvent.

Sensitivity of the assay for Cu,Zn superoxide dismutase 3 (SOD3), the predominant form of SOD in serum, can be increased, and interferences caused by low-molecular-weight substances in the serum can be reduced by conducting the assay at pH 10 with xanthine/xanthine oxidase and acetylated cytochrome c (cyt c) as superoxide generator and detector, respectively. Serum SOD3 activity was assayed und...

The title compound, [Cu(2)(C(18)H(19)N(3)O(2))(2)]·2C(2)H(6)OS or [Cu(2)(SalenN(3)H)(2)]·2DMSO, where SalenN(3)H is the multidentate Schiff base 2,2'-[(3-aza-pentane-1,5-di-yl)bis-(nitrilo-methyl-idyne)]diphenolate dianion and DMSO is dimethyl sulfoxide, is a solvated dinuclear Cu(II) complex. The neutral complex is built from two Cu(SalenN(3)H) units related by an inversion center. All heteroa...
