Thus, we place brain iron uptake in the context of the neurovascular unit of the adult brain. Last, we propose that BMVEC iron is involved in the aggregation of amyloid-β peptides leading to the progression of cerebral amyloid angiopathy which often occurs prior to dementia and the onset ...
Therapeutic phlebotomy of a unit of blood (which contains about 250 mg of iron) may be performed up to three times per week. When the iron stores become depleted, reaccumulation of iron is prevented by 4–6 phlebotomies per year. In asymptomatic patients, periodic determination of serum ...

, such as ferritin, siderophilin, and hemosiderin. Hemoglobin, found in the red blood cells, is responsible for transport of oxygen to the tissue cells and constitutes about two-thirds (mass) of all iron present in the human body. An adult human may contain about 4 to 6 grams of iron....
transfusions deliver a very large amount of iron, which can be a concern. A single unit of packed red blood cells (PRBCs) contains about 200 to 250 mg of iron.7Most often, patients receive two units each time they are transfused, so that’s an extra 500 mg of iron in just one ...

Anemia is a condition in which the blood is unable to carry sufficient oxygen from the air we breath to the tissues of our bodies, as mentioned earlier (Chapter 12). Among the consequences of severe anemia are pallor of the skin, shortness of breath, extreme weakness, heart palpitations, ...
Assuming that serum ferritin concentration reflects iron stores per unit of fat-free body mass, it seems likely that, per unit of fat-free body mass, iron stores of the preadolescent boys and girls in our studies were somewhat greater than those of premenopau- sal women, but substantially ...
