Ample evidence now exists to show that the nutritional anawmia, or milk anaemia, of babies bears a very close resemblance to the milk aneemia of rats, but whereas young rats in whom anwemia is induced by prolonged milk feeding suffer from a deficiency of copper as well as of iron, and require both copper and iron for their cure4, it is not yet proven that copper deficiency plays any part in the...

Aluminium, iron and copper are all implicated in the aetiology of neurodegenerative diseases including Alzheimer's disease. However, there are very few large cohort studies of the content of these metals in aged human brains. We have used microwave digestion and TH GFAAS to measure aluminium, iron and copper in the temporal, frontal, occipital and parietal lobes of 60 brains donated to the Cogn...

the aim of this work was to develop a selective cloud point extraction method for the separation and preconcentration of copper(ii) prior to spectrophotometric determination. for this purpose dithizone was used as a complexing agent and the experimental solution was acidified with sulfuric acid. triton x-114 was used as a surfactant and after phase separation, based on the cloud point of the mi...

The determination of serum copper is of value in a number of metabolic studies, particularly in the investigation of the anemia of chronic infection. Presented here, together with illustrative data, is a method for determining copper in serum, based on the direct extraction of copper carbamate from serum with isoamyl alcohol. Burch et aa. in their method for serum iron have demonstrated that su...

Divalent metal transporter-1 (DMT1) is a divalent cation transporter that plays a key role in iron metabolism by mediating ferrous iron uptake across the small intestine. We have previously identified several small molecule inhibitors of iron uptake (4). Using a cell line that stably overexpresses DMT1, we screened the ability of these inhibitors to specifically block this transporter's activit...

Chemical-looped reverse water–gas shift reaction was investigated using transition metal/metal oxides as oxygen carriers. Iron is identified the only promising carrier that shows compelling CO 2 splitting reactivity. A chemically looped developed an iron-based carrier. Compared with conventional catalytic conversion processes, chemical looping method has advantage of high selectivity and cheap ...

Administration of niridazole to rats poisoned with copper caused a significant increase in both the urinary and biliary excretion of the metal. Although the urinary excretion of iron was increased by the drug, iron excretion was significantly decreased during the drug-induced excretion of copper after copper poisoning. Formation of a copper-niridazole chelate or chelates before excretion in the...

electric arc furnace dust (eafd) of ferromanganese production units, in the form of slurry, contains tar, alkalies, manganese, zinc, iron, silica, calcium, aluminum and other elements. a hydrometallurgical route based on solvent extraction technique was investigated for selective separation of manganese from the dust. leaching of the eafd resulted in an aqueous feed containing 4 g/l of manganes...
