Abstract

Icariside II is a flavonoid extracted from Epimedium that has antioxidant, anti‑inflammatory and antiapoptotic effects. The aim of the present study was to evaluate the effects icariside II on diabetic cardiomyopathy in streptozotocin-induced diabetic rats. Icariside II treatment improved body weight, heart/body weight ratio and fasting blood glucose in diabetic model rats. Icariside II was demonstrated to reduce the expression levels of creatine kinase and lactate dehydrogenase in serum, and to lower cardiac oxidative stress, inflammation and apoptosis levels in diabetic rats. Icariside II treatment induced phosphoinositide 3‑kinase and phosphorylated‑Akt expression, and suppressed inducible nitric oxide synthase (iNOS) and nuclear factor (NF)‑κB protein expression in diabetic rat. Results from the present study suggested that treatment with icariside II improved diabetic cardiomyopathy in streptozotocin‑induced diabetic rats by activating the Akt/NOS/NF‑κB pathway.

Abstract

Investigation into the temperature programmed reduction (TPR) of bulk or γ-Al2O3 supported molybdenum trioxide using n-hexane as a carbon source in hydrogen was carried out. The resulting catalyst was evaluated using dibenzothiophene (DBT) as a model compound for the hydrodesulfurization (HDS). The results show that the utilization of n-hexane can lower the temperature, to fulfill carburization to some extent. For DBT HDS, however, there exists an optimal temperature at which carburization is carried out, leading to a high activity of the resulting catalyst. In these experiments, it has been found that the resulting catalyst exhibits the highest DBT HDS activity if the precursor, MoO3/γ-Al2O3, with 30% theoretic loading, is carburized at 620°C under atmospheric pressure and 0.025 mol ratio of n-hexane to hydrogen in carburizing reagents.
