Recurrent miscarriage is a less recognized feature of Wilson’s disease and adequate treatment can alter the outcome of pregnancies favourably. Wilson’s disease is a recessively inherited disorder of copper metabolism due to mutations in the ATP7B gene, which encodes for a coppertransporting P-type ATPase. Recurrent miscarriage is a complication of untreated Wilson’s disease. It has been reporte...

Hemocyanin is a copper-containing protein which occurs in the blood of a number of species of arthropods and molusks. The extent of the reversible combination with molecular oxygen is a function of the partial pressure of oxygen, and like the formation of oxyhemoglobin is affected by changes in acidity and salt concentration. The ratio of combined molecular oxygen to copper is 02:2Cu in all the...

Ascorbate in an aqueous solution is easily oxidized by molecular oxygen in the presence of cupric ion, thus producing reactive oxygen species and exhibiting cytotoxicity. In order to increase the antitumor activity of ascorbate, we used the innocuous form of cupric ion complexed with glycylglycylhistidine, a tripeptide designed to mimic the specific Cu(ll) transport site of albumin molecule. Al...

this study represents the first report on the chemical composition and biological activity of trifolium angustifolium var. angustifolium. the major components of the essential oil were identified as hexatriacontene (23.0%), arachidic acid (15.5%) and α-selinene (10.0%). the main constituents of the fatty acid obtained from the petroleum ether extract were identified as palmitic acid (29.8%), li...

Cupric oxide (CuO) nanoparticles were prepared by the chemical route by calcinations at a higher temperature from 300 o C to 400 o C. For the comparison transmission electron microscopy (TEM) and x-ray diffraction (XRD) measurements were made through JCPDS. There is good agreement between data produced by spectroscopy and the microscopic measurements.

A novel fluorescent chemodosimeter based on 1,8-naphthyridine exhibits high selectivity to Zn(2+) and Cu(2+). When 1-(7-acetamino-1,8-naphthyridyl)-2-(6-diacetaminopyridyl)ethene was mixed with CuCl2, hydrolysis of the acetamino group catalyzed by Cu(2+) complex was first observed. Resulting from coordination and hydrolysis catalyzed by the corresponding complex of Zn(2+) or Cu(2+), the highly ...

oxygen delignified kraft pulp from eucalyptus (e. urophylla × e. grandis) was catalytically pretreated in aerobic condition using ammonium persulfate in present of catalists like cupric acetate and/or cobalt acetate in acetic acid-water solution, i. e. s2o82--cu2+, s2o82--co2+ and s2o82--(cu2++co2+). final bleached pulp after pretreatment with the three catalytic systems showed higher delignifi...
