  • intestinal
  • Dietary non-heme iron primarily exists in an oxidized (Fe 3+ ) form that is not bioavailable and must first be reduced to the Fe2+ form by a ferrireductase enzyme, that uses vitamin C as a coenzyme, before being transported across the intestinal epithelium by the divalent metal transporter 1 (DMT1).

  • putative
  • Iron is exported by ferroportin 1 (the only putative iron exporter) across the basolateral membrane of the enterocyte into the circulation (absorbed iron) where it binds to transferrin and is transported to sites of use and storage. (scielo.br)
  • erythropoietin
  • The response to recombinant human erythropoietin (rHuEpo) is determined primarily by the availability of iron. (oup.com)

  • Conclusions
  • Conclusions: The risk of ID in obese Mexican women and children was 2-4 times that of normal-weight individuals at similar dietary iron intakes. (wur.nl)
  • urinary
  • Yet overall, the daily loss of iron by desquamation is approximately 25% that of daily urinary iron excretion ( Molin and Wester, 1976 ). (frontiersin.org)
  • Clinical
  • Clinical trials have found that intravenous iron replacement can improve exercise ability in people with heart failure, but we don't know how if cheaper oral iron supplements have the same effect. (bhf.org.uk)
  • In canine medicine the occurrence of AI has been documented decades ago, but little information is available about the prevalence of AI in the clinical setting and on the hematopoietic response to the inflammation magnitude. (unipd.it)
  • From the search of 22,669 clinical records of the five-years period (2005-2010), 3452 dogs were included for analysis to assess how the degree of anemia is related to an increased in severity of inflammation. (unipd.it)
  • Investigation of ID in the clinical practice mostly relies on laboratory tests which fall into two categories: measurements providing evidence of iron depletion in the body and measurements reflecting iron deficient red cell production. (scielo.br)

  • Erythrocytes contain up to 65-70% of body iron. (scielo.br)
  • As stated above, under physiological conditions, there is a balance between iron absorption and iron loses in the human body. (scielo.br)
  • When you exercise your body creates inflammation, or specifically an inflammatory cytokine called interleukin-6 (IL-6). (trainright.com)
  • Iron is not actively excreted from the body, however the skin is a key organ in iron hemostasis as iron is lost through the skin by desquamation (Figure 2 ). (frontiersin.org)
