Pregnant brindled (brin) mice were injected at 16 or 19 days gestation with 2 doses of CuCl/sub 2/ 6 mcg/g/dose, separated by 12 h, and sacrificed 6 h after the second. The copper conc. in placenta (P) and kidneys (K) of uninjected (UI) brin mice were higher than in UI controls, while conc. in liver (L) and fetal carcass (F) were lower. After injection (I), placental ...

Copper is a trace element that is required for cellular respiration, neurotransmitter biosynthesis, pigment formation, antioxidant defense, peptide amidation, and formation of connective tissue. Abnormalities of copper metabolism have been linked with neurologic disorders that affect movement, such as Wilson ...

Wilson's disease results in excess tissue accumulation of copper and is often complicated by skeletal and mineral abnormalities. The authors investigated vitamin D metabolism in rats fed a copper-laden diet rendering hepatic copper content comparable with that found in ...

Trichopoliodystrophy (also known as Menkes' kinky or steely hair disease), a recessive sex-linked syndrome, is characterized by severely retarded mental and physical development, convulsions, a particular phenotype and abnormalities of the hair, bones and arteries. Very low levels of copper and ceruloplasmin in the serum confirm the diagnosis. This rare ...

Introduction. Outside of Wilson's Disease, abnormal copper metabolism is a rare condition. In pregnancy, excess copper levels can be associated with intrauterine growth restriction, preeclampsia and neurological disease. Case Report. A 32 year old Gravida 4 para 2012 with an obstetrical history complicated by ...

On separate occasions young cattle were injected intrarumenally with 99Mo or 64Cu or intravenously with 64Cu. The metabolism of the isotopes were compared to evaluate metabolic changes associated with molybdenum-induced copper deficiency. Molybdenum-99 metabolism was the same in both controls and experimental ...

Hepatic abnormalities in Long-Evans Cinnamon (LEC) rats, an animal model of Wilson disease (WD), were restored by the expression of the human ATP7B cDNA under the control of CAG promoter. Expression of ATP7B transcript and protein in the liver of the transgenic rats resulted in the restoration of biosynthesis of holoceruloplasmin and biliary copper ...

Normal copper homeostasis is essential for human growth and development. Copper deficiency, caused by genetic mutations, inadequate diet or surgical interventions, may lead to cardiac hypertrophy, poor neuronal myelination, blood vessel abnormalities and impaired immune response. Copper overload is associated with ...

Copper mutations, inadequate diet or surgical interventions, may lead to cardiac hypertrophy, poor neuronal myelination, blood vessel abnormalities and impaired immune response. Copper overload is associated with morphological and ...

The copper content of various organs of `brindled' female heterozygotes and male mice affected by this X-linked mutation are documented at the last day of intrauterine development, at 1 day after birth and at 11 days of age. The findings indicate defective placental transfer of copper in utero, and an even more marked defect in intestinal absorption of ...

Decreased amounts of the serum copper-binding protein caeruloplasmin (hypocaeruloplasminaemia) are one of the characteristic abnormalities of copper metabolism that are found in all neonatal mammals. In the present study we have investigated the mechanism responsible for hypocaeruloplasminaemia found in neonatal ...

Breakthrough in treatment of Alzheimer's disease with a shift from irrational dangerous chelation therapy to rational safe evidence based oral zinc therapy. Evidence based medicine: After synthesizing the best available clinical evidence I conclude that oral zinc therapy is a conscientious choice for treatment of free copper toxicosis in individual patients with Alzheimer's ...

Wilson disease (WD) is a genetic disorder of copper metabolism associated with severe hepatic, neurological, and psychiatric abnormalities. In WD, the billiary copper excretion is impaired and copper accumulates in tissues, particularly in the liver and the brain. The affected gene, ATP7B, ...

The deviations from normal health produced by abnormalities in trace mineral metabolism in patients with renal disease and renal disorders produced by deficiencies or excesses of these trace minerals serve as the focus for this symposium on trace minerals and the kidney. Zinc, the trace mineral of most interest of the nephrologist, and aluminum, the ...

Genetic disorders of copper metabolism, including Menkes kinky hair disease (MD), occipital horn syndrome (OHS) and Wilson's disease (WD) are reviewed with a focus on the neurological aspects. MD and OHS are X-linked recessive disorders characterized by a copper deficiency. Typical features of MD, such as neurologic disturbances, ...

The report is a review of current knowledge of the distribution of copper in the environment and living things. Metabolism and the effects of copper in the biosphere are also considered. Copper compounds are common and widely distributed in nature. They a...

The kinds and quantities of copper species present in influent and effluent waters were determined in samples collected from power stations located adjacent to marine, estuarine, and freshwater ecosystems. Copper concentration and speciation differed with the site, season, and mode of operation of the station. Under normal operating conditions, the ...

1. Copper concentrations were low in many organs of Moblo/Y mice, but very high in the gut. Absorption of 64Cu was seen to be very low when related to the absorption of cyano[57Co]cobalamin. The results in Moblo/+ mice were intermediate. 2. Copper therapy temporarily ameliorated many effects of the mutation in Moblo/Y mice, but did not improve the rate of ...

Abnormalities of the skeletal and urogenital system are discussed which result from an interference with the metabolism of calcium in cadmium workers.
