Iron is an essential element for life on earth, participating in a plethora of cellular processes where one-electron transfer reactions are required. Its essentiality, coupled to its scarcity in aqueous oxidative environments, ...

The data on the relationship between iron deficiency and infection are conflicting. Some researchers conclude that mild iron deficiency is beneficial for immunity, whereas others contend that any deficit is not good for ...

OBJECTIVES: We determined the iron (Fe), zinc (Zn), and copper (Cu) contents of common Chilean foods and assessed the intakes of these elements in a population living in Santiago, Chile. METHODS: We selected foods most ...

We evaluated the effect of iron-supplemented milk on 86 healthy infants who were followed from 3 to 12 months of age. Whole milk was supplemented with 15 mg elementary iron as ferrous sulphate and 100 mg ascorbic acid per ...

The involvement of cytosolic nitric oxide (NO) and mitochondrial superoxide radical (O2 ·-) production was evaluated as a mechanism triggering liver oxidative stress in lindane (40 mg/kg) or L-3,3′,5-triiodothyronine (T3, ...

Intestinal epithelial cells have an active apical iron uptake system that is involved in the regulated absorption of iron. By the action of this system, intestinal cells acquire increasing amounts of iron with time. Since ...

Recent evidence shows that iron induces the endocytosis of the iron transporter dimetal transporter 1 (DMT1) during intestinal absorption. We, and others, have proposed that iron-induced DMT1 internalization underlies the ...

Siderophores are iron-chelating compounds that aid iron uptake, one of the key strategies for microorganisms to carve out ecological niches in microbially diverse environments. Desferrioxamines are the principal siderophores ...
