Further experience with the differential ferrioxamine test (Fielding, 1965) for the measurement of body-iron chelation has led to modifications which include (1) an improved standard for the estimation of ferrioxamine, (2) simplified preparation of the test dose, (3) restriction of fluid during the test and (4) simplified methods of calculation. The principle of the test remains the same: an in...

Heart disease is the leading cause of mortality and one of the main causes of morbidity in beta-thalassemia. Patients with homozygous thalassemia may have either a severe phenotype which is usually transfusion dependent or a milder form that is thalassemia intermedia. The two main factors that determine cardiac disease in homozygous β thalassemia are the high output state that results from chro...

The combination of α-acetamidocinnamic acid (HACA) and different N , pyridines (dPy) leads to crowded Zn( ii ) metal centers. increasing bulkiness competes with the chelation enhanced effect (CHEF) in resulting quantum yields.
