introduction: in  major b -thalassemia impaired biosynthesis of beta hemoglobin leads to accumulation of unpaired alpha hemoglobin chain. an iron overload generates oxygen-free radicals which ultimately leads to tissue injury. the aim of this investigation was to evaluate serum antioxidants in patients with major b -thalassemia and those with minor thalassemia in comparison with respective age ...

the binding, release and oxidation of oxygen occur at the heme group iron ion. hemoglobinoxidation-reduction studies have been previously performed using spectroelectrochemistry (sec) andhave provided insight into the hemoglobin electron transfer process and more specifically, into theheme group electronic factor and subunit interaction influences. in this study, the number of fullerenecarbon a...
