2016/12/19
Background: Quantitative data on the mucosal uptake and serosal transfer of nonheme-iron absorption in humans and the effects of calcium on these components are limited.Objective: Our object...
Diet and iron status of nonpregnant women in rural Central Mexico
Iron status nonpregnant women diet Mexico
2016/12/19

Iron indexes and total antioxidant status in response to soy protein intake in perimenopausal women
Antioxidant status ferritin iron indexes lipoprotein(a) menopause soy-protein isolate oxidation perimenopausal women
2016/12/19
Background: Elevated iron stores, oxidative stress, and estrogen deficiency may place postmenopausal women at greater risk of heart disease and cancer than premenopausal women.Objective: The...
Iron absorption in breast-fed infants:effects of age,iron status,iron supplements,and complementary foods
Infants human milk breast milk nonheme-iron absorption stable isotopes iron status dietary iron intake complementary food iron supplements dietary regulator adaptation
2016/12/19
Background: Iron supplements are often recommended for older breast-fed infants, but little is known about factors affecting iron absorption from human milk or supplements.Objective: We inve...
Marginal iron deficiency without anemia impairs aerobic adaptation among previously untrained women
Iron defi ciency without anemia iron depletion women aerobic training ·VO2 max maximal oxygen uptake serum transferrin receptors serum ferritin
2016/12/17
Background: Iron deficiency without anemia has been shown to reduce both muscle-tissue oxidative capacity and endurance in animals. However, the consequences of iron deficiency in humans remain u...
Treatment of iron deficiency in goitrous children improves the efficacy of iodized salt in Côte d'Ivoire
Iodine iron defi ciency anemia goiter iodized oil iodized salt children Cô te d’Ivoire
2016/12/17
Background: In many developing countries, children are at high risk of both goiter and iron deficiency anemia. Iron deficiency adversely affects thyroid metabolism and may reduce the efficacy of ...
Iron bioavailability from iron-fortified Guatemalan meals based on corn tortillas and black bean paste
Iron bioavailability stable isotopes ferrous fumarate corn tortillas Na2 EDTA disodium ethylenediaminetetraacetate NaFeEDTA sodium iron ethylenediaminetetraacetate girls Guatemala corn masa flour
2016/12/17
Background: Corn masa flour is widely consumed in Central America and is therefore a potentially useful vehicle for iron fortification.Objective: The goal was to evaluate the bioavailability...
Usefulness of serum transferrin receptor and serum ferritin in diagnosis of iron deficiency in infancy
Transferrin receptor serum ferritin ratio of transferrin receptor to ferritin iron deficiency infants
2016/6/8
Background: The serum transferrin receptor (TfR) and the ratio
of TfR to serum ferritin (TfR:SF) have been shown to be useful
as early indicators of iron deficiency.
Objective: The objective of thi...
Adaptation in iron absorption: iron supplementation reduces nonheme-iron but not heme-iron absorption from food
Iron supplementation heme iron nonheme iron iron absorption fecal ferritin serum ferritin
2016/6/8
Background: Results of cross-sectional studies suggest that in
healthy people, iron absorption adapts to meet physiologic
needs and stabilize iron stores, but this has not been adequately
tested in...

Iron manganese zinc intestinal absorption, Caco-2 cells
2016/6/8
Background: Divalent metal transporter 1 (DMT1), HFE, and
stimulator of iron transport (SFT) are transmembrane proteins that
have been implicated in the regulation of iron homeostasis.
Objective: T...
The prevalence of iron deficiency anemia is
likely to be higher in athletic populations and groups, especially
in younger female athletes, than in healthy sedentary
individuals. In anemic individua...
Iron requirements in pregnancy and strategies to meet them
Iron requirements absorption pregnancy, strategies therapy women iron fortification
2016/6/7
Iron requirements are greater in pregnancy
than in the nonpregnant state. Although iron requirements are
reduced in the first trimester because of the absence of menstruation,
they rise steadily th...
Iron needs during pregnancy: do we need to rethink our targets?
Iron anemia requirements pregnancy supplementation, hemoglobin
2016/6/7
This paper argues that current estimates of the
need for absorbed iron, estimates of iron absorption, and hence
estimates of iron requirements for pregnant women greatly
depend on what is determine...

Hemoglobin anemia polycythemia iron defi- ciency birth outcomes preeclampsia iron supplementation
2016/6/7
An association between moderate anemia and
poor perinatal outcomes has been found through epidemiologic
studies, although available evidence cannot establish this relation
as causal. Anemia may not...
