RESUMEN
Diabetic cardiomyopathy, as one of the main cardiac complications in diabetic patients, is identified to connect with oxidative stress that is due to interruption in balance between reactive oxygen species or/and reactive nitrogen species generation and their clearance by antioxidant protection systems. Transcription factor the nuclear factor erythroid 2-related factor 2 (Nrf2) plays a significant role in maintaining the oxidative homeostasis by regulating multiple downstream antioxidants. The Nrf2 plays a significant role in ARE-mediated basal and inducible expression of more than 200 genes that can be grouped into numerous categories as well as antioxidant genes and phase II detoxifying enzymes. On the other hand, activation of Nrf2 by natural and synthetic therapeutics or antioxidants has been revealed effective for the prevention and treatment of toxicities and diseases connected with oxidative stress. Hence, recently focus has been shifted toward plants and plant-based medicines in curing such chronic diseases, as they are supposed to be less toxic. In this review, we focused on the role of some natural products on diabetic cardiomyopathy through Nrf2 pathway.

In this study, we made an attempt to evaluate the potential of Cucurbita maxima seeds oil (CSO) against high-fat diet (HFD)-induced obesity in rats. We investigated the effect of CSO (100 mg/kg body weight) supplementation over 30 days on the changes of HFD-induced obese rats in body weight, biochemical parameters and lipid profile as well as investigated the effects of CSO on the histopathological changes. Oral administration with CSO revealed significant diminution in body weight gain, glucose and insulin levels, which altered the activity of lipid profile and restored the pathological alterations. It demonstrated that CSO had considerably altered these parameters when evaluated with HFD control rats. In conclusion, this study established that CSO prevents the HFD-induced obesity by altering the markers important to lipid metabolism.
