Ex Input:
Question: Does novel Manganese-Porphyrin Superoxide Dismutase-Mimetic widen the Therapeutic Margin in a Preclinical Head and Neck Cancer Model?
Answer: MnBuOE widens the therapeutic margin by decreasing the dose of radiation required to control tumor, while increasing normal tissue resistance to RT-mediated injury. This is the first study to quantitatively demonstrate the magnitude of a single drug's ability to radioprotect normal tissue while radiosensitizing tumor.

Ex Output:
yes
