The copper level in the serum of 1280 and liver of 200 goats raised in the mountain areas of Khuzestanprovince, Iran were determined. Copper, molybdenum and iron content of soil and pastures as well as sulfurcontent of the pastures were seasonally estimated. Mean serum copper levels of goats in Behbahan,Ramhormoz, Eizeh and Masjed-Soleyman districts were 8.14 ± 0.21, 1.98 ± 0.12, 7.74 ± 0.11 an...

The effects of copper pollution on the polyphenol content, color, and antioxidant activity of wine, as well as correlations among these factors, were investigated. Copper had clear influences on wine polyphenol content. At low copper concentrations, the concentrations of nearly all polyphenols increased, and the antioxidant activity values of the wine also increased. When the copper concentrati...

1. When copper chloride is allowed to act on Aspergillus niger there is at first a period during which there is no change in the rate of the production of carbon dioxide, following which the rate of respiration falls. The interval of no change is called the latent period. 2. When the copper is removed from the external solution before the end of the latent period this interval is prolonged. The...

Established marinas act as gateways for human impact on the natural environment. One of the major ways this occurs is through the leaching of biocides from antifouling paints applied to marine vessels. These paints often contain copper, which can have an effect on non-target organisms, especially those in fouling communities within marinas. In this study, I hypothesized that the level of copper...

Serum zinc and copper concentrations of 156 healthy children (6-12 years old) were measured by the atomic absorption spectrophotometric method. The average serum zinc concentration was 92 +/- 13 mug/100 ml (mean +/- S.D.) with a range of 62-127 mug/100 ml. No statistically significant age or sex differences were found in serum zinc levels. The mean serum copper level was 109 +/- 17 mug/100 ml w...

We investigated categorical regions and appearances of gold, silver and copper color, and glossiness for CG spheres with various chromaticities, lightnesses, and contrast glosses. It was found that the chromaticity regions of brown and yellow changed into gold color, those of gray and black into silver color, and a part of brown region changed into copper color with increase of contrast gloss. ...

OBJECTIVE To investigate the relationship between copper speciation and microbial features (microbial communities and copper tolerance level) in order to determine the adverse effect of different forms of Cu on microorganisms. METHODS Tessier's sequential extraction procedure was used to qualify the different Cu forms (exchangeable, carbonate bound, Fe/Mn oxide bound, residue and organic matt...

Adverse outcomes of pregnancy increase among women with high density of hemoglobin. This study evaluates the effects of iron supplementation on serum copper level in pregnant women with hemoglobin higher than 13.2 g/dl. Sixty two pregnant women with Hemoglobin >13.2 g/dl and normal serum copper levels in their 13-18 weeks of gestation were randomized into case and control groups. From 20th week...

Here, we present further characterization of cryptococcal CUF1 in copper homeostasis. We demonstrated that CUF1 was involved both in copper acquisition and in copper detoxification in response to copper variation. This was verified by direct measurement of the quantity of intracellular copper with flame atomic absorption spectrometry (FAAS) and molecular evidence. In copper-limited growth, the ...
