Iron uptake by mammalian cortical neurons
Annals of Neurology, 1984AbstractAlthough iron accumulates in the brain in a number of pathological conditions, including Hallervorden‐Spatz syndrome, Parkinson's disease, and neurosyphilis, studies of brain iron metabolism have been performed only rarely. Neuronal‐enriched cultures were prepared from fetal mouse brain. After 18 days the cells were exposed to radiolabeled iron.

Ferritin and iron uptake by reticulocytes
British Journal of Haematology, 1983Summary.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.

Iron uptake regulation in Pseudomonas aeruginosa
BioMetals, 2009The Pseudomonas genus belongs to the gamma division of Proteobacteria and many species produce the characteristic yellow-green siderophore pyoverdine, and often a second siderophore, of lower affinity for iron. These bacteria are known for their ability to colonize different ecological niches and for their versatile metabolism.

Hepatic Ferritin Uptake and Hepatic Iron
Hepatology, 1990The effect of hepatic iron on the uptake of ferritin was studied by perfusing livers from normal, iron deficient and iron–loaded rats with 125I–labeled ferritin. Unlabeled ferritin with tracer doses of labeled ferritin in concentrations of 0.02 to 2,700 nmol/L were studied.

At the normal pH range of arable soils, available Fe is not enough to meet plant requirement. Deficiency of Fe occurs less in acid soils than calcareous soils with higher pH. Iron deficiency is a major health problem for humans around the world.

Iron uptake in Salmonella typhimurium
Canadian Journal of Microbiology, 1971The iron-uptake system of S. typhimurium is energy-dependent, repressed by growth in the presence of iron, and apparently specific for iron. Iron uptake is stimulated by a sideramine and by phenolic acids. In mutants unable to synthesize enterobactin, the uptake system remains functional. Iron inside the cell is not available to external chelators.

Iron uptake studies on erythroid cells
Biochimica et Biophysica Acta (BBA) - General Subjects, 1978Iron uptake from 55Fe-labelled transferrin, ferric citrate and the two fungal sideramines, ferricrocin and fusigen was studied using four erythroid cell cultures: Friend virus-transformed erythroleukemic cells (mouse), transformed bone marrow cells, Detroit-98 (human), reticulocytes (bovine), bone marrow cells (rabbit).

Molecular mechanisms governing Arabidopsis iron uptake
Trends in Plant Science, 2015Plants are the principal source of dietary iron (Fe) for most of Earth's population and Fe deficiency can lead to major health problems. Developing strategies to improve plant Fe content is a challenge because Fe is essential and toxic and therefore regulating Fe uptake is crucial for plant survival.

UPTAKE OF IRON BY MATURE ERYTHROCYTES
Australian Journal of Experimental Biology and Medical Science, 1967SummaryMature red cells take up iron not bound to transferrin when they are incubated with plasma in vitro. The iron is not incorporated into haemoglobin, but is probably attached to stromal iron acceptors. Red cells from blood with saturated transferrin have more iron‐acceptor sites occupied than have red cells from blood with unsaturated transferrin.

Uptake by plants of iron from iron chelates
Journal of Plant Nutrition, 1984Abstract Several studies have been conducted with BPDS as a trapping agent of Fe2+ to prevent iron uptake by plants. The BPDS does inhibit iron uptake although the BPDS chelated iron is available to plants particularly at low solution pH. Such results, however, do not prove obligatory reduction of Fe3+ chelates before absorption of iron even though ...
