Zinc and Copper Concentrations in Breastmilk
The concentration of essential trace elements in breastmilk is an important topic in infant nutrition. The interesting paper by Örun, et al. [1] needs to be put in context in the light of previous research on the topic. Comprehensive reviews of breastmilk zinc [2,3] and copper [4] concentrations have addressed the maternal (constitutional and environmental) factors modulating the secretion of t...

متن کاملEffects of supplemental dietary phytase and pharmacological concentrations of zinc on growth performance and tissue zinc concentrations of weanling pigs.
Three experiments were conducted to determine the effects of phytase, excess Zn, or their combination in diets for nursery pigs. In all experiments, treatments were replicated with five to seven pens of six to seven pigs per pen, dietary Ca and available P (aP) levels were decreased by 0.1% when phytase was added to the diets, excess Zn was added as ZnO, a basal level of 127 mg/kg of Zn (Zn sul...
متن کاملZinc, iron, copper, and magnesium concentrations in tissues of rats fed various amounts of zinc.
An experiment was conducted with rats to determine the effects on the tissue concentrations of Zn, Fe, Cu, and Mg of feeding various amounts of zinc. The rats were pair-fed one of the following diets for four weeks: Diet A, a zinc-deficient diet; a diet containing the recommended amoun of zinc (diet A plus 55 microgram of zinc per gram of diet), or diet A plus 550 microgram zinc per gram of die...
متن کاملMeasurement of intracellular free zinc concentrations accompanying zinc-induced neuronal death.
Toxic zinc influx may contribute to selective neuronal death after transient global ischemia. We previously used the high-affinity (K(D) = 27 nm) fluorescent dye mag-fura-5 to detect initial increases in neuronal intracellular free Zn(2+) ([Zn(2+)](i)) associated with brief Zn(2+) exposure. Here we used the specific low-affinity Zn(2+) indicator Newport Green (K(D) = 1 microm) to measure the pe...
