Nutrition Information Brief—Copper

Moderate to severe copper deficiency is typified by decrements in serum copper and CP activity ( 6 ). CP carries most circulating copper; thus, changes in blood copper likely reflect changes in CP concentrations. Using serum Cu and CP activity as bioindicators of copper status is, however, complicated because infection and …

The purpose of the present study is to clarify the association between Se, Cu, and Mg levels with thyroid cancer using a meta-analysis approach. We searched articles indexed in PubMed published as …

Isotopic composition of serum zinc and copper in healthy …

No significant difference in isotopic composition of serum zinc or copper with respect to healthy controls and ASD children were identified. However, the isotopic composition of serum copper in boys was found to be enriched in 65 Cu in comparison to previously published healthy adult copper isotopic composition. Furthermore, in both …
