This study investigated the effects and possible molecular mechanism of casein kinase-2 interacting protein-1 (CKIP-1) silencing on bone regeneration during rat mandibular distraction osteogenesis (DO).CKIP-1 silencing by chitosan/si-CKIP-1 was employed and analyzed both in rat mandibular DO models in vivo and in cultured rat mandible bone marrow stromal cells (BMSCs) in vitro.Gross observation, micro–computed...
A laser-cooled rubidium fountain clock is studied at Shanghai Institute of Optics and Fine Mechanics (SIOM). One important characteristic of the setup was, instead of six laser beams used in normal fountains, a fold optical path (FOP) was used to trap, cool, and launch atoms, which decreased laser power by 60% and the optical system was simplified greatly. This fountain clock had been operated with...
