Enhanced integrin-mediated human osteoblastic adhesion to porous amorphous calcium phosphate/poly（L-lactic acid） composite

引用

Chinese Medical Journal 2014年第19期127卷 3443-3448页

作者： Huang Xin Qi Yiying Li Weixu Shi Zhongli Weng Wenjian Chen Kui he rongxin Department of Orthopaedic Surgery Second Affiliated HospitalMedical College of Zhejiang University Hangzhou Zhejiang310009 China Department of Materials Science and Engineering Zhejiang UniversityHangzhou Zhejiang 310027 China

Background The initial osteoblastic adhesion to materials characterizes the first phase of cell-material interactions and influences all the events leading to the formation of new bone. In a previous work, we developed a novel amorphous calcium phosphate （ACP）/poly（L-lactic acid）（PLLA） material that demonstrated morphologic variations in its microstructure. The aim of this study was to investigate the initial interaction between this material and osteoblastic cells. Cellular attachment and the corresponding signal transduction pathways were investigated. Methods A porous ACP/PLLA composite and PLLA scaffold （as a control） were incubated in fetal bovine serum （FBS） containing phosphate-buffered saline （PBS）, and the protein adsorption was determined. Osteoblastic MG63 cells were seeded on the materials and cultured for 1, 4, 8, or 24 hours. Cell attachment was evaluated using the MTS method. Cell morphology was examined using scanning electron microscopy （SEM）. The expression levels of the genes encoding integrin subunits αl, α5, αv, β1, focal adhesion kinase （FAK）, and glyceraldehyde-3-phosphate dehydrogenase （GAPDH） were determined using real-time reverse transcription polymerase chain reaction （RT-PCR）. Results The ACP/PLLA material significantly increased the protein adsorption by 6.4-fold at 1 hour and 2.4-fold at 24 hours, compared with the pure PLLA scaffold. The attachment of osteoblastic cells to the ACP/PLLA was significantly higher than that on the PLLA scaffold. The SEM observation revealed a polygonal spread shape of cells on the ACP/ PLLA, with the filopodia adhered to the scaffold surface. In contrast, the cells on the PLLA scaffold exhibited a spherical or polygonal morphology. Additionally, real-time RT-PCR showed that the genes encoding the integrin subunits αl, αv, β1, and FAK were expressed at higher levels on the ACP/PLLA composite. Conclusions The ACP/PLLA composite promoted protein adsorption and osteoblastic adhesion. The enhanced cell adhesi

A high torque dual 3-phase permanent magnet vernier machine with strong fault-tolerance

引用

Science China Technological Sciences 2024年第10期67卷 3275-3284页

作者： XU YuWen WANG Bo WANG rongxin CheNG Ming HUA Wei School of Electrical Engineering Southeast University

The field modulation effect has been proposed and investigated in various electric machine topologies. Among them, permanent magnet vernier machines(PMVMs) have attained intensive research due to the high torque density and simple ***, the performance of PMVMs in terms of fault tolerance is seldom mentioned. This article proposes a novel dual 3-phase fault-tolerant PMVM with segregated concentric windings. Benefiting from the field modulation effect, the PMVM can generate high torque with low PM flux. The low PM flux also implies small fault currents in the short-circuit case. Therefore, the PMVM exhibits inherent good fault-tolerant capability without sacrificing torque performance. Two independent 3-phase modular winding sets are adopted to improve redundancy. To realize the physical and electrical isolation, each winding set is controlled by a standard 3-phase inverter. The healthy performance and fault tolerance of the proposed machine are evaluated by finite element analysis and verified by experimental tests. The results infer its advantages in healthy conditions and various fault scenarios,including open-circuit, short-circuit, and interturn short-circuit conditions.

目的探索重组甲状旁腺素[rhPTH（1—34）]间断注射对磨损颗粒诱导的小鼠颅骨骨溶解的抑制作用。方法选择8周龄C57BL／J6小鼠48只，数字随机分为空白对照组、钛颗粒对照组、低剂量rhPTH组及高剂量rhPTH组（每组12只）。利用钛颗粒建立颅骨骨溶解模型，空白对照组及钛颗粒对照组术后手术区域局部注射生理盐水，低剂量及高剂量钛颗粒组术后分别局部注射30μg·kg-1·d-1及60μg·kg-1·d-1 rhPTH（1．34），每周间断注射3次。间断注射2周后处死实验动物，收集颅骨组织及外周血。采用计算机断层扫描（micro—CT）分析标本骨溶解程度，运用实时（real-time）聚合酶链反应（PCR）及ELISA技术分析颅骨组织及外周血中骨保护素（OPG），核因子KB受体活化因子配体（RANKLigand，RANKL）基因及蛋白的表达情况。结果rhPTH局部注射显著抑制了钛颗粒诱导的小鼠颅骨骨溶解程度。与钛颗粒对照组对比，rhPTH（1—34）明显促进OPGmRNA及蛋白的表达，rhPTH治疗组RANKIMOPG比值明显低于钛颗粒对照组（P〈0．05）。结论rhPTH（1—34）可有效抑制颗粒诱导小鼠骨溶解。
