Abstract

Oxidative stress associated with iron deficiency anaemia in a murine model was studied feeding an iron-deficient diet. Anaemia was monitored by a decrease in hematocrit and haemoglobin. For the 9 week study an increase in total iron binding capacity was also demonstrated. Anaemia resulted in an increase in red blood cells (RBC) oxidative stress as indicated by increased levels of fluorescent heme degradation products (1.24-fold after 5 weeks; 2.1-fold after 9 weeks). The increase in oxidative stress was further confirmed by elevated levels of methemoglobin for mice fed an iron-deficient diet. Increased haemoglobin autoxidation and subsequent generation of ROS can account for the shorter RBC lifespan and other pathological changes associated with iron-deficiency anaemia.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ROS can be released to the vasculature and neighboring tissues, not only damaging RBCs themselves.

    “Since the ROS concentration can be increased near the membrane, not only are the RBCs themselves damaged, ROS can be released to the vasculature and neighboring tissues (Nagababu et al., 2008).”

  • Heme degradation correlates with immunoglobulin G binding to the RBC membrane, which is associated with denaturation of hemoglobin; denatured hemoglobin, heme degradation products and free iron promote removal of RBCs from circulation.

    “Heme degradation has been reported to correlate with immunoglobulin G binding to the RBC membrane, which in turn is associated with denaturation of Hb.Denatured Hb and heme degradation products as well as free iron, promote removal of RBCs from circulation.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
