Coculturing scaffolds with seeded cells in vitro is an indispensable process for construction of engineered tissues. It is essential to understand effects of the constituent particles of scaffold on seeded cells. In this study, we investigated the influence of nano-sized hydroxyapatite (nHAP) particles on the proliferation and osteogenic differentiation of(More)
This study was performed in 36 rabbits to investigate the role of midkine (MK) in the resorption of herniated intervertebral discs. The L1-2 disc was excised and immersed in one of three kinds of solution for two hours before relocation into the L4 epidural space. In the MK-treated group, the weight of relocated intervertebral discs decreased more over time(More)
Three-phase AC-voltage regulatior systems using silicon controlled rectifier (SCR) have been broadly applied in industrial field.This paper introduces a novel design of three-phase AC-voltage regulation trigger circuitry with SCR and STM32 microcontroller, and presents its application in an energysaving design of oil extractor control system. This design(More)
