In this study, a pot experiment was conducted to evaluate the effect of phosphate (PO4 (3-)) addition on iron (Fe) cycling in mangrove ecosystem. Kandelia obovata (S. L.), one of the dominant mangrove species in the southeast of China, was cultivated in rhizoboxes under three different levels of P concentrations. Results showed the solid-phase Fe distribution and Fe(II)/Fe(III) values in both t...

Soybean plants, Glycine max (L.) Merrill, in standard solution received 2.5 mum ferric ethylenediamine di(o-hydroxyphenylacetate (FeEDDHA) and 0 to 128 mum phosphorus. Their stem exudates contained: 32 to 52 mum Fe, 120 to 5000 mum P, and 120 to 165 mum citrate. Electrophoresis of exudates with high P caused Fe trailing that precluded identification of any major form of Fe. Exudate with low P g...

Twenty-four lambs, averaging 29 kg, were used to determine the effect of supplemental dietary Fe on performance and Cu, P, Zn and Mn utilization. Treatments consisted of supplemental Fe at 0, 300, 600 or 1,200 mg/kg diet as ferrous carbonate. The basal diet contained 154 mg Fe/kg diet and consisted of 90% Coastal bermudagrass pellets, 9.45% group corn, .5% sodium chloride and .05% vitamin mix. ...

Heart failure is the leading cause of mortality in patients with transfusional iron (Fe) overload in which myocardial iron uptake ensues via a transferrin-independent process. We examined the ability of L-type Ca channel modifiers to alter Fe uptake by isolated rat hearts and ventricular myocytes. Perfusion of rat hearts with 100 nmol/L Fe and 5 mmol/L ascorbate resulted in specific Fe uptake o...

This experiment was designed to determine whether dietary hemoglobin (Hgb) iron (Fe) could 0271-5317/$ – see fro doi:10.1016/j.nutres.2 4 Corresponding a E-mail address: p sustain normal Fe status in growing rats adequate or deficient in copper (Cu). Forty-eight weanling rats were divided into 3 groups, each consisting of 16 animals. One group was fed a diet containing 40 mg Fe/kg as ferrous su...

BACKGROUND Iron (Fe) deficiency anemia remains the largest nutritional deficiency disorder worldwide. How the gut acquires iron from nano Fe(III), especially at the apical surface, is incompletely understood. OBJECTIVE We developed a novel Fe supplement consisting of nanoparticulate tartrate-modified Fe(III) poly oxo-hydroxide [here termed nano Fe(III)], which mimics the Fe oxide core of ferr...
