Dihydromyricetin Improves Endothelial Dysfunction in Diabetic Mice via Oxidative Stress Inhibition in a SIRT3-Dependent Manner.

Dihydromyricetin (DHY), a flavonoid component isolated from Ampelopsis grossedentata, exerts versatile pharmacological activities. However, the possible effects of DHY on diabetic vascular endothelial dysfunction have not yet been fully elucidated. In the present study, male C57BL/6 mice, wild type (WT) 129S1/SvImJ mice and sirtuin 3 (SIRT3) knockout (SIRT3) mice were injected with streptozotocin (STZ, 60 mg/kg/day) for 5 consecutive days.

High-Performance Li-Ion Capacitor Based on an Activated Carbon Cathode and Well-Dispersed Ultrafine TiO Nanoparticles Embedded in Mesoporous Carbon Nanofibers Anode.

A novel Li-ion capacitor based on an activated carbon cathode and a well-dispersed ultrafine TiO nanoparticles embedded in mesoporous carbon nanofibers (TiO@PCNFs) anode was reported. A series of TiO@PCNFs anode materials were prepared via a scalable electrospinning method followed by carbonization and a postetching method. The size of TiO nanoparticles and the mesoporous structure of the TiO@PCNFs were tuned by varying amounts of tetraethyl orthosilicate (TEOS) to increase the energy density and power density of the LIC significantly.
