Comparison of methods used to measure serum iron in the presence of iron gluconate or iron dextran.
Monaghan et al. (6 ) in a Scottish population. Our study provides similar findings in an Italian population, without any differences between regional origins. Moreover, 7 of 16 subjects with the 7/7 genotype had STB within the reference interval. These data, in agreement with the recent study by Rudenski and Halsall (7 ), confirm that the Gilbert genotype is not always expressed. There is a nee...

متن کاملPhysiological Characterization of a Synechococcus Sp. (cyanophyceae) Strain Pcc 7942 Iron-dependent Bioreporter for Freshwater Environments
The complex chemical speciation of Fe in aquatic systems and the uncertainties associated with biological assimilation of Fe species make it difficult to assess the bioavailability of Fe to phytoplankton in relation to total dissolved Fe concentrations in natural waters. We developed a cyanobacterial Fe-responsive bioreporter constructed in Synechococcus sp. strain PCC 7942 by fusing the Fe-res...
متن کاملAdaptation of iron absorption in men consuming diets with high or low iron bioavailability.
BACKGROUND Short-term measurements of iron absorption are substantially influenced by dietary bioavailability of iron, yet bioavailability negligibly affects serum ferritin in longer, controlled trials. OBJECTIVE Our objective was to test the hypothesis that in men fed diets with high or low iron bioavailability, iron absorption adapts to homeostatically maintain body iron stores. DESIGN He...
متن کاملEffect of EDTA on the bioavailability to rats of fortification iron used in Egyptian balady bread
The effectiveness of EDTA compounds on iron fortificants for potential use in Egyptian balady bread was tested in sixty SpragueDawley weanling male rats by the haemoglobin regeneration efficiency (HRE) method. To confirm HRE-derived findings, eight groups of ten animals were repleted with a modified American Institute of Nutrition (1977; AIN) 76A diet, fortified with ferric phosphate, electroly...
