Iron, copper and immunocompetence.
Microminerals including copper and iron are essential to immunity and health in human beings. The development of powerful tools in analytical cell biology and molecular genetics has facilitated efforts to identify specific cellular and molecular functions of trace elements in the maturation, activation and functions of host defence mechanisms. Selected recent reports about the role of copper an...

Objective. To describe the micronutrient nutritional status of a national sample of 1-11 year old Mexican children surveyed in 2006 in National Health and Nutrition Survey (ENSANUT 2006) and their association with dietary and sociodemographic factors. Materials and methods. Serum samples were used (n=5 060) to measure the concentrations of ferritin, transferrin receptor, zinc, copper and magnes...
متن کاملIron, copper and fetal development.
Pregnancy is a period of rapid growth and cell differentiation for both the mother and fetus. Consequently, it is a period when both are vulnerable to changes in dietary supply, especially of those nutrients that are marginal under normal circumstances. In developed countries this vulnerability applies mainly to micronutrients. Even now, Fe deficiency is a common disorder, especially in pregnan...
متن کاملInhibition of iron and copper uptake by iron, copper and zinc.
Interactions of micronutrients can affect absorption and bioavailability of other nutrients by a number of mechanisms. In aqueous solutions, and at higher uptake levels, competition between elements with similar chemical characteristics and uptake process can take place. The consequences of these interactions may depend on the relative concentrations of the nutrients. In this work, we measure t...
متن کاملInitial Stages of Oxidation of Copper and Copper-iron Alloy
The initial oxidation stages of copper and copper-iron alloys have been studied by the AtomProbe Field Ion Microscope (AP-FIM). The depth profiles of copper oxide formed in-situ were successfully determined. The composition of the oxide was close to the value of Cu20, but a large concentration fluctuation was found. The interface between the oxide and the metal was found to be diffuse, the widt...
