BACKGROUND 6-Hydroxydopamine (6-OHDA) was used for ex vivo purging of bone marrow from neuroblastoma cells before autologous transplantation. However, this concept failed because of the rapid autoxidation of 6-OHDA, which leads to the generation of c

The question regarding chirality in nitroxides was rigorously investigated, namely, (a) are multiple EPR and ENDOR spectra expected from nitroxides with chiral centers, (b) which structures provide multiple structures and (c) under what conditions (t

Ferritin is the main intracellular iron storage protein. Ferritin iron may be released by many reducing agents including ascorbate. In this work we report ferritin to catalyze the oxidation of ascorbate. The kinetics of this process were studied in d
