Antioxidant Activity of Ethanol and Water Extracts from Lentil (Lens Culinaris)

Abstract The purpose of this study was to evaluate the antioxidative activities of water and ethanolic extracts from lentil (Lens Culinaris). The antioxidant effects of lentil extracts were evaluated, including 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity and ferric reducing antioxidant power (FRAP). We also evaluated the protection effect on hydrogen peroxide-induced oxidative damage in PC-12 cells via propidium iodide (PI) staining using a flow cytometer. Lentil extracts decreased cell death in PC-12 cells due to hydrogen peroxide-induced oxidative damage in a dose-dependent manner. The findings of this study suggested that lentil has the potential to protect against hydrogen peroxide-induced cell damage and should be considered as a prospective functional food

Strategic Asset Allocation Of Credit Guarantors

How to manage the portfolio of credit guarantors is important in practice and public policy, but has not been investigated well in the prior literature. We empirically compare four different approaches in managing credit guarantor portfolios. The four approaches are equal weighted, minimum variance, mean variance optimization and equal risk contribution methods. In terms of risk return ratio, the mean variance optimization model performs best in out-of-sample test. This result contrasts with previous findings against mean variance optimization. Our results are robust. The results do not change as the characteristics of guarantee portfolio vary
