NAD+ metabolism and its roles in cellular processes during ageing
The overall performance of CRE-AgNPs was equivalent to results of earlier studies which used daily doses as high as 800 mg/kg body weight

All these findings support the theory that DOX induces oxidative stress and mitochondria-mediated apoptosis which goes hand in hand with adaptive responses to protect cardiac myocytes (Figure 1
