Practice guidelines for vacuum-assisted delivery in Japan were revised in 2014 to improve clinical safety. We aimed to determine the success rates of vacuum delivery before and after the release of the revised guidelines.

This retrospective observational study included singleton deliveries at term gestation. Success rate of vacuum…[Read more]

Herein, we report hierarchical 3D NiMn-layered double hydroxide (NiMn-LDHs) shells grown on conductive silver nanowire (Ag NWs) cores as efficient, low-cost, and durable oxygen reduction reaction (ORR)/oxygen evolution reaction (OER) bifunctional electrocatalysts for metal-air batteries. The hierarchical 3D architectured Ag NW@NiMn-LDH catalysts…[Read more]
