Background: The role of the placenta in regulating micronutrient transport in response to maternal status is poorly understood.Objective: We investigated the effect of prenatal nutritional supplementation on the regulation of placental iron and zinc transport.Methods: In a randomized trial in rural Gambia [ENID (Early Nutrition and Immune Development)], pregnant women were allocated to 1 of 4 n...

We investigated the effect of prolonged iron supplementation of low birthweight infants on plasma zinc concentrations. Thirty infants (neonatal weight 820-2000 g) were examined at 6 or 12 months of life to assess their iron state and plasma zinc concentration. All of them were feeding on iron fortified formulas, which supply about 1 mg/kg/day of iron. In addition, 14 of them had been receiving ...

The aim of this study was to assess the efficacy of a national program of consumption of fortified milk "Liconsa" on the nutritional status of iron and zinc in pre-school children (3-5 y). The study was conducted in 77 healthy children of both genders. 54 of them consumed Liconsa fortified milk (GCLFL) and 23 consumed no fortified milk (GR). Iron status was determined by measuring hemoglobin an...

UNLABELLED Child eating behaviors play an important role in nutrient intake, ultimately affecting child growth and later outcomes in adulthood. The study assessed the effects of iron-folic acid and zinc supplementation on child temperament and child eating behaviors in rural Nepal. Children (N = 569) aged 4-17 months in Sarlahi district, southern Nepal were randomized to receive daily supplemen...

BACKGROUND The purpose of this study was to evaluate the levels of zinc (Zn), copper (Cu), iron (Fe) and zinc/ copper ratio in the serum of patients with cutaneous leishmaniasis in Qom Province, center of Iran. METHODS Serum levels of zinc and copper were determined by flame atomic absorption spectrophotometer and serum iron concentration was measured by using an Auto Analyzer. The study grou...

Treatment of newborn pigs with supplemental iron is a common procedure utilized to prevent neonatal anemia. The aim of this study was to investigate the hepatic distribution and intracellular metabolism of iron-dextran, a widely used colloidal-iron-carbohydrate preparation. Piglets were injected intramuscularly with iron-dextran (50 mg Fe/kg body wt) at 1 d of age. Hepatocytes and sinusoidal ce...

Simulations of gastro-intestinal digestion, used to estimate in vitro iron and zinc availability, were performed on two kinds of samples: (i) samples with decreased phytate contents from whole pearl millet flour and (ii) nondephytinized or dephytinized samples from two pearl millet grain fractions, a decorticated fraction with low fiber and tannin contents and a bran fraction with high fiber an...

To investigate the relationships of trace element concentrations vs hematopoiesis and iron parameters, we measured lead, copper, zinc, cadmium, and ferritin levels in 251 healthy adolescents. Concentrations of trace metals were determined by atomic absorption spectrophotometry. There were no significant gender-related differences in serum copper or serum cadmium concentrations. However, blood l...

Data are presented of a 5-day balance study for iron, zinc, and copper in seven patients with short bowel syndrome on oral nutrition. The small bowel remnant of these patients varied from 40 to 110 cm (mean 64 cm) and was radiologically normal in all patients. The study was carried out an average 2.7 yr (range 1 to 5 yr) after intestinal resection. Balance materials (diets, urine, and stools) w...
