Two-dimensional transition metal carbides and nitrides (MXenes) nanosheets with high photothermal conversion efficiency as well stability can efficiently generate remarkable hyperthermia for therapy (PTT) of cancer. However, mono-MXenes cannot exhibit precise diagnosis treatment to complete ablation cancer cells in the PTT process. To overcome this dilemma, an "all-in-one" nanoplatform titanium carbide (Ti

Abstract Objectives This study was designed to explore the effect and mechanism of matrine, an active component Chinese traditional medicine, on isoproterenol-induced acute cardiotoxicity in rats. Methods Acute myocardial injury induced rats by daily subcutaneous injection isoproterenol (85 mg/kg) for two days. Haemodynamic biochemical parameters were measured histopathological examination performed. Key findings Chronic oral administration matrine (50, 100 or 200 mg/kg per day 10 days)...
