Determination of serum ferritin is an important means of assessing body iron stores. Trace amounts of ferritin normally present in serum are detectable by sensitive radioimmunoassay techniques or an enzyme immunoassay procedure. Ferritin normally accounts for no more than a very small fraction of the total iron in serum, but generally maintains a stable concentration that is proportional to the...

the presence of a low transferrin level is explained by this abnormal tumour ferritin having the capacity to bind 300t, of the serum iron. Excessive serum levels of ferritin may lead to an increased iron transfer to hepatic cells.:' In this patient the localisation of excessive iron is consistent with such an effect mediated by tumour ferritin. This in turn may have produced a stimulus to iinte...

Ferritins are the main iron storage proteins found in animals, plants, and bacteria. The capacity to store iron in ferritin is essential for life in mammals, but the mechanism by which cytosolic iron is delivered to ferritin is unknown. Human ferritins expressed in yeast contain little iron. Human poly (rC)-binding protein 1 (PCBP1) increased the amount of iron loaded into ferritin when express...

Background: Iron deficiency and its related anemia, which is the world’s most widespread nutritional deficiency, can be one of the possible consequences of regular blood donation. This research was carried out to compare iron stores in regular blood donors and first-time blood donors in Tehran Regional Blood Transfusion Center. Materials and Methods: This study was carried out on 2,149 male bl...

OBJECTIVES To assess nutritional iron status and anemia prevalence in children less than 5 years old at public daycare centers in the city of Recife, PE, Brazil. METHODS A cross-sectional study, with a systematic random sampling of 162 children aged 6 to 59 months. Nutritional iron status was assessed in terms of body iron reserves (serum ferritin), transferrinemia (serum iron, total iron bin...

OBJECTIVES To analyze and compare the evolution of hematological parameters and body iron content between exclusively breastfed late-preterm and term newborns during the first two months of life. METHODS Cohort study. Weight, length, head circumference, body mass index, hemoglobin, hematocrit, reticulocytes, total iron-binding capacity, transferrin saturation, serum iron and ferritin were mea...

      Hydroxypyridinone iron chelators are currently the main candidates for development of orally active iron chelating alternatives to desferrioxamine (DFO). In the present study, the relative efficacy and liver toxicity of a bidentate chelator, 2-methyl-3-hydroxypyridin-4-one (MHPO), was studied in iron overloaded rats and compared with those of DFO. For iron overloading, rats received i.p. ...

OBJECTIVE To determine the diagnostic accuracy of serum iron and total iron binding capacity (TIBC) in detection of iron deficiency. STUDY DESIGN Descriptive, analytical study. PLACE AND DURATION OF STUDY Department of Chemical Pathology and Endocrinology, from January 2013 to October 2015. METHODOLOGY Data of 1,815 patients with results of serum iron, TIBC and ferritin from January 2013 ...

OBJECTIVES To compare the effects of wheat flours fortified with NaFeEDTA, FeSO4 and elemental iron (electrolytic iron), in improving iron status in anemic students. METHODS Four hundreds anemic students (11 to 18 years old) were divided into four groups and given wheat flour fortified with different iron fortificants at different concentrations: control group (no added iron); NaFeEDTA group ...
