| 1 | A review of UHMWPE wear-induced osteolysis:the role for early detection of the immune response显示文摘In a world where increasing joint arthroplasties are being performed on increasingly younger patients,osteolysis as the leading cause of failure after total joint arthroplasty(TJA) has gained considerable attention.Ultra-high molecular weight polyethylene wear-induced osteolysis is the process by which prosthetic debris mechanically released from the surface of prosthetic joints induces an immune response that favors bone catabolism, resulting in loosening of prostheses with eventual failure or fracture. The immune response initiated is innate in that it is nonspecific and self-propagating, with monocytic cells and osteoclasts being the main effectors. To date, detecting disease early enough to implement effective intervention without unwanted systemic side effects has been a major barrier. These barriers can be overcome using newer in vivo imaging techniques and modules linked with fluorescence and/or chemotherapies. We discuss the pathogenesis of osteolysis, and provide discussion of the challenges with imaging and therapeutics. We describe a positron emission tomography imaging cinnamoyl-Phe-(D)-Leu-Phe-(D)-Leu-Phe-Lys module,specific to macrophages, which holds promise in early detection of disease and localization of treatment.Further research and increased collaboration among therapeutic and three-dimensional imaging researchers are essential in realizing a solution to clinical osteolysis in TJA. | Adrese M Kandahari Xinlin Yang Kevin A Laroche Abhijit S Dighe Dongfeng Pan Quanjun Cui | 2016 | Bone Research2016，4，2： | 7 |
| 2 | Field-free approaches for deterministic spin–orbit torque switching of the perpendicular magnet显示文摘All-electrical driven magnetization switching attracts much attention in next-generation spintronic memory and logic devices,particularly in magnetic random-access memory(MRAM)based on the spin–orbit torque(SOT),i.e.SOT-MRAM,due to its advantages of low power consumption,fast write/read speed,and improved endurance,etc.For conventional SOT-driven switching of the magnet with perpendicular magnetic anisotropy,an external assisted magnetic field is necessary to break the inversion symmetry of the magnet,which not only induces the additional power consumption but also makes the circuit more complicated.Over the last decade,significant effort has been devoted to field-free magnetization manipulation by using SOT.In this review,we introduce the basic concepts of SOT.After that,we mainly focus on several approaches to realize the field-free deterministic SOT switching of the perpendicular magnet.The mechanisms mainly include mirror symmetry breaking,chiral symmetry breaking,exchange bias,and interlayer exchange coupling.Furthermore,we show the recent progress in the study of SOT with unconventional origin and symmetry.The final section is devoted to the industrial-level approach for potential applications of field-free SOT switching in SOT-MRAM technology. | Hao Wu Jing Zhang Baoshan Cui Seyed Armin Razavi Xiaoyu Che Quanjun Pan Di Wu Guoqiang Yu Xiufeng Han Kang L Wang | 2022 | Materials Futures2022，1，2： | 0 |
