Neurochemical Research, 1985
Dynamic studies of iron metabolism in brain are generally unavailable despite the fact that a number of neurologic conditions are associated with excessive accumulation of iron in central nervous tissue. Cortical non-neuronal (glial) cultures were prepared from fetal mouse brain. After 13 days the cultures were exposed to radiolabeled iron.

Iron Absorption and Cellular Uptake of Iron
1994Iron balance is regulated primarily by keeping the absorptive process attuned to body requirements. While iron loss from the body is quantitatively as important as iron absorption, excretion is limited and plays a more passive role [1]. It has been known for many years that iron is absorbed in the small intestine.

Ferrous iron uptake byBifidobacterium breve
Biological Trace Element Research, 1989Bifidobacterium breve transports ferrous iron in preference to the ferric form in a saturable, concentration-dependent manner with an optimum pH of 6. Iron transport is highly temperature sensitive. Two transport systems with apparent Km's of 86 +/- 27 and 35 +/- 20 microM (p greater than 0.01) were distinguished, one operating at high iron ...

Iron uptake byBifidobacterium thermophilum protoplasts
Biological Trace Element Research, 1993Protoplasts of Bifidobacterium thermophilum were prepared by a combination of lysozyme and protease digestion, and ferrous iron uptake studies were carried out. Little, if any, iron was internalized by the protoplasts, although large amounts of iron were bound to the protoplast surface.

Critical Reviews in Biochemistry and Molecular Biology, 1999
Recent information gained from genetic and biochemical studies of iron transport in yeast, coupled with the identification of specific mutations causing iron uptake disorders in mice and man, has provided new clues about the mechanisms involved in iron uptake.

Monitoring Iron Uptake by Siderophores
2014Iron is an important element for almost all forms of life. In order to get access to this essential nutriment, Pseudomonads produce two major siderophores, pyoverdine PVD and pyochelin (PCH). Uptake of iron in bacterial cells can be monitored accurately using (55)Fe.

Iron Uptake by Rabbit Reticulocytes
British Journal of Haematology, 1973Summary. In keeping with present concepts of internal iron exchange, it is thought that the two iron binding sites of transferrin molecules bind and donate iron in a similar manner. Since recent data, however, have suggested that iron attached at one iron binding site may be more readily available to cells than iron bound to the other site, a further ...
