BACKGROUND The effect of maternal iron status on fetal iron deposition is uncertain. OBJECTIVE We used a unique stable-isotope technique to assess iron transfer to the fetus in relation to maternal iron status. DESIGN The study group comprised 41 Peruvian women. Of these women, 26 received daily prenatal supplements containing iron and folate (n = 11; Fe group) or iron, folate, and zinc (n ...

Seedlings of endangered Dade County pine, Pinus elliotii var. densa, must survive long enough to form symbiotic associations with ectomycorrhizal fungi that assist uptake of mineral nutrients. Although plants need nitrogen (N), phosphorus (P), and potassium (K) in relatively large quantities, pine seedlings also may need relatively high amounts of iron (Fe). We hypothesized that iron would limi...

The health benefits of cranberries have long been recognized. However, the mechanisms behind its function are poorly understood. We have investigated the iron-binding properties of quercetin, the major phenolic phytochemical present in cranberries, and other selected phenolic compounds (chrysin, 3-hydroxyflavone, 3',4'-dihydroxy flavone, rutin, and flavone) in aqueous media using UV/vis, NMR an...

Translocation of micronutrients was investigated in Phaseolus vulgaris (var. Annapurna) grown on soil amended with paper mill sludge. The plants of P. vulgaris were grown in soil amended with 20%, 40%, 60%, 80%, and 100% paper mill sludge to study the accumulation and translocation of iron (Fe), zinc (Zn), cadmium (Cd), copper (Cu), chromium (Cr) and lead (Pb) in plant parts (shoot, root, leave...

Mineral processing, pyro- and hydrometallurgical processes of auriferous sulfide ores porphyry copper deposits (PCDs) generate arsenopyrite-rich wastes. These wastes are disposed into the tailings storage facilities (TSF) in which toxic arsenic (As) is leached out acid mine drainage (AMD) generated due to oxidation arsenopyrite (FeAsS). To suppress oxidation, this study investigated passivation...

To investigate the correlations among seminal plasma Magnesium (Mg), Phosphorus (P), Potassium (K), Calcium (Ca), Chromium (Cr), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Selenium (Se), Molybdenum (Mo) and Iodine (I) concentrations and semen parameters [1– 15]. 500 fertile and 1000 infertile males provided a standardized semen specimen. Total Magnesium (Mg), Phosphorus (P), Potassium (...

Catalytic activity and stability of iron hexacyanocobaltate (FeIII[CoIII(CN)6], Fe–Co) for organophosphate hydrolysis are improved by doping divalent metal ions (MII = MnII, NiII, or CuII). The catalytic a series (FeIII0.8MII0.3)[CoIII(CN)6] (FeM–Co compounds) was examined in mixed solution water ethanol [9:1 (v/v)] containing disodium p-nitrophenyl phosphate (p-NPP) at 60 °C. FeM–Co compounds ...

Siderophore facilitates iron availability in soil, but its assistance in iron transportation to different plant parts is not reported till date. Therefore, it is worthwhile to study the effect of siderophore produced by Pseudomonas for iron acquisition in the presence and absence of iron. To study these effects, two siderophore-producing Pseudomonas aeruginosa strains RSP5 and RSP8 were selecte...

BACKGROUND The use of microencapsulated ferrous fumarate sprinkles is a new approach for home fortification. Iron and hematologic status may affect the absorption of iron from sprinkles. OBJECTIVE The objective was to measure the absorption (corrected erythrocyte incorporation of (57)Fe) of 2 different doses of iron from sprinkles added to a maize-based complementary food provided to infants ...

BACKGROUND There is a need to determine whether iron absorption from iron amino acid chelates is protected from inhibition by dietary phytate and regulated normally by iron status. OBJECTIVE The objective of this study was to compare iron absorption from ferrous sulfate, ferrous bisglycinate, and ferric trisglycinate in whole-maize meal; to determine whether iron from ferrous bisglycinate and...
