Although iron is the fourth most abundant element in the Earth's crust, bioavailable iron limits marine primary production in about one third of the ocean. This lack of iron availability has implications in climate change because the removal of carbon dioxide from the atmosphere by phytoplankton requires iron. Using literature values for global fish biomass estimates, and elemental composition ...

SYNOPSIS A method is described for measuring the plasma unsaturated iron-binding capacity in the presence of very high concentrations of iron as iron-dextran. The procedure utilizes 59Fe to label the apotransferrin with subsequent separation of ionic iron from transferrin-bound iron on an ion exchange or Sephadex G.25 column. The unsaturated iron-binding capacity has been measured in rabbits an...

in order to study the effect of iron chelate (fe-eddha) on some biochemical characteristic of safflower (carthamus tinctorius l.) under two irrigation regimes, a field experiment was set up a split-plot based on randomized block design with four replication in 2011 in a research field of the faculty of agriculture at shahed university. in this study the main plots consisted of two levels of irr...

background: a close relationship has been reported between level of serum iron and ischemic heart diseases which is either brought about through direct effect of serum iron on myocardial cells or as an indirect result of elevated serum lipid profile. a widespread use of iron supplements has been observed due to the high prevalence of iron deficiency anemia. yet an elevated serum lipid is strong...

That lime-induced chlorosis can be alleviated by the application of iron salts has been recognized for a hundred years. As early as 1845, GRIS (8) treated chlorotic plants with iron and obtained positive results; his experiments have been repeatedly confirmed. Opinions differ widely, however, as to the comparative amount and state of iron in chlorotic leaves. Various investigators have presente...

Severe anemia, which commonly occurs in patients with chronic renal failure, usually results from deficient production of erythropoietin. Other causative factors, i.e., iron deficiency, frequently contribute to the anemia, especially in patients on chronic hemodialysis. This has led to the almost routine use of intravenous iron-dextran. Recently, recombinant erythropoietin has been used in the ...

BACKGROUND Maternal smoking has been known to have a negative impact on the well being of the developing fetus. Prenatal smoking has been associated with premature births, low birth weight and with certain birth defects. Small research studies have also found a negative correlation between maternal smoking and neonatal body iron. OBJECTIVES To study and compare the relationship between matern...

A recent prospective study showed that higher consumption of red meat and total protein was associated with increased risk for inflammatory polyarthritis. We therefore prospectively examined the relationship between diet (in particular, protein, iron, and corresponding food sources) and incident rheumatoid arthritis (RA) among 82,063 women in the Nurses' Health Study. From 1980 to 2002, 546 inc...

BACKGROUND/AIM Iron is a vital constituent of hemoglobin, myoglobin, and some mitochondrial enzymes; therefore, body iron deficiency may result in reduced aerobic capacity. The aim of this study was to evaluate the effects of daily oral iron supplementation on body iron status, and the maximal oxygen uptake (VO2max) in female athletes with latent iron deficiency, as well as with iron-deficiency...
