The exact mechanism of translate mechanical signals of the focal adhesion kinase (FAK) into osteoblast differentiation power. PDL cells and MG63 cells were under-100 kPa for different periods. The tension force of focal adhesion kinase (FAK) phosphorylation increases rapidly and upregulation of osteogenic protein expression in periodontal ligament cells, but not in MG63 cells with FAK antisense oligonucleotides...
We incorporate the idea by Akashi et al. which utilize disulfide bonds in forming the porous hydrogel. We further develop a system using γ-PGA as scaffold and disulfide bonds cleavage as the critical point of cell sheet detach system. Cytotoxicity tests showed good biocompatibility of the matrix PVDF membranes. Finally, the cell sheet detachment was successfully performed by adding cysteine after...
A prototype wireless torque measuring device is designed to measure high-speed rotation torque. The aim of this gadget is to measure torque in harsh environment where physical contact is not possible or very difficult. The gadget is very helpful in new era of wireless industrial applications. It is a non-contact and low power consumption gadget. It is based on wireless ZigBee protocol and very smart...
In practical engineering, water supply systems often work in variable working condition and their energy Consumption depends largely on the adjustment methods. Through the experiments, pumps in parallel were operated by many kinds of regulate methods in varied flow or in variable frequency, the Q-?? graphs in different schemes were obtained and energy saving effects of the systems variable frequency...
