OBJECTIVE To examine the relationship between iron status and non-specific symptoms among female students. DESIGN Cross-sectional study. SUBJECTS AND SETTING Data were collected from 255 female students, aged 15 to 30 years, attending Curtin University of Technology, Perth or secondary schools in the Perth metropolitan area. MAIN OUTCOME MEASURES(More)
Limited Australian data are available on iron status and factors affecting iron status in young women. Iron status was assessed in a population of 15-30 year old students using standard haematological and biochemical tests. Data were collected on demographic details and known risk factors for iron deficiency, including diet. Iron deficiency was present in(More)
The uptake of liver ferritin labelled with 125I or 59Fe by guinea-pig reticulocytes has been studied to investigate the characteristics of the uptake process, compare it with transferrin uptake and determine whether ferritin-iron is utilized by the cells in haem synthesis. The results confirmed that guinea-pig reticulocytes, but not mature erythrocytes,(More)
Transferrin and ferritin endocytosis and exocytosis by guinea-pig reticulocytes were studied using incubation with pronase at 4 degrees C to distinguish internalized and membrane-bound protein. Internalization of both transferrin and ferritin occurred in a time- and temperature-dependent fashion. Transferrin endocytosis was more rapid than that of ferritin.(More)
Earlier studies have shown that transferrin binds to specific receptors on the reticulocyte surface, clusters in coated pits and is then internalized via endocytic vesicles. Guinea-pig reticulocytes also have specific receptors for ferritin. In this paper ferritin and transferrin endocytosis by guinea-pig reticulocytes was studied by electron microscopy(More)
