When zirconia is attached to CNPs (CZNPs), the ceria atom tends to remain in a Ce3+ form and its efficacy as a free radical scavenger thus increases. We determined the effectiveness of CNP and CZNP antioxidant activities

Cystic echinococcosis (CE) is a worldwide zoonotic disease. At present, the treatment options of CE are limited. The main drugs used in clinical chemotherapy of echinococcosis are albendazole and mebendazole, but they mainly exert longterm antiparasitic effects based on high doses. Therefore, there is an urgent need for effective and safe anti-CE drugs. Previous studies have identified harmine (HM)
