abstract：:Cancerous breast hyperthermia is seemingly associated with non-neurological vasodilation modulated by nitric oxide (NO). NO, associated with enhanced immune response, is produced autocatalytically involving ferritin as the supplier of Fe2+, which catalyses the formation of NO. NO, in turn, releases Fe2+ from ferritin....
