| 1 | Bone infection site targeting nanoparticle-antibiotics delivery vehicle to enhance treatment efficacy of orthopedic implant related infection显示文摘Orthopedic implants account for 99%of orthopedic surgeries,however,orthopedic implant-related infection is one of the most serious complications owing to the potential for limb-threatening sequelae and mortality.Current antibiotic treatments still lack the capacity to target bone infection sites,thereby resulting in unsatisfactory therapeutic effects.Here,the bone infection site targeting efficacy of D6 and UBI29-41 peptides was investigated,and bone-and-bacteria dual-targeted nanoparticles(NPs)with D6 and UBI29-41 peptides were first fabricated to target bone infection site and control the release of vancomycin in bone infection site.The results of this study demonstrated that the bone-and-bacteria dual-targeted mesoporous silica NPs exhibit excellent bone and bacteria targeting efficacy,excellent biocompatibility and effective antibacterial properties in vitro.Furthermore,in a rat model of orthopedic implant-related infection with methicillin-resistant Staphylococcus aureus,the growth of bacteria was evidently inhibited without cytotoxicity,thus realizing the early treatment of implant-related infection.Hence,the bone-and-bacteria dual-targeted molecule-modified NPs may target bacteria-infected bone sites and act as ideal candidates for the therapy of orthopedic implant-related infections. | Bin’en Nie Shicheng Huo Xinhua Qu Jingjing Guo Xi Liu Qimin Hong You Wang Jianping Yang Bing Yue | 2022 | Bioactive Materials2022，7，10： | 2 |
| 2 | Essential role of Msx1 in regulating anterior-posterior patterning of the secondary palate in mice显示文摘Development of the secondary palate displays molecular heterogeneity along the anterior-posterior axis;however, the underlying molecular mechanism remains largely unknown. MSX1 is an anteriorly expressed transcription repressor required for palate development. Here, we investigate the role of Msx1 in regional patterning of the secondary palate. The Wnt1-Cre-mediated expression of Msx1(Rosa Msx1^(Wnt1-Cre))throughout the palatal mesenchyme leads to cleft palate in mice, associated with aberrant cell proliferation and cell death. Osteogenic patterning of the hard palate in Rosa Msx1^(Wnt1-Cre)mice is severely impaired, as revealed by a marked reduction in palatine bone formation and decreased expression of the osteogenic regulator Sp7. Overexpression and knockout of Msx1 in mice show that the transcription repressor promotes the expression of the anterior palate-specific Alx1 but represses the expression of the medialposterior palate genes Barx1, Meox2, and Tbx22. Furthermore, Tbx22 constitutes a direct Msx1 target gene in the secondary palate, suggesting that Msx1 can directly repress the expression of medial-posterior specific genes. Finally, we determine that Sp7 is downstream of Tbx22 in palatal mesenchymal cells,suggesting that a Msx1/Tbx22/Sp7 axis participates in the regulation of palate development. Our findings unveil a novel role for Msx1 in regulating the anterior-posterior growth and patterning of the secondary palate. | Shicheng Zhu Hanjing Song Liangjun Zhong Suman Huo Yukun Fang Wanxin Zhao Xueqin Yang Zhong-Min Dai Rui He Mengsheng Qiu Zunyi Zhang Xiao-Jing Zhu | 2022 | Journal of Genetics and Genomics2022，49，1： | 2 |
| 3 | Secure output synchronization of heterogeneous multi-agent systems against false data injection attacks显示文摘This paper studies secure output synchronization for heterogeneous multi-agent systems against false data injection(FDI)attacks.Both the sensors and actuators of agents may be injected into FDI attacks.To mitigate the malicious impact of these attacks on synchronization performance,a desired reference model,which is combined with an auxiliary system,is first designed for each agent to simulate its normal system dynamics.Then,based on this reference model,a state feedback cooperative controller and a static output feedback cooperative controller,which consist of adaptive compensators,are proposed,respectively.The integrated control protocols can ensure that the output synchronization error is small by adjusting some designed parameters even in the presence of FDI attacks.An illustrative example is employed to demonstrate the effectiveness of the proposed method. | Shicheng HUO Dalin HUANG Ya ZHANG | 2022 | Science China(Information Sciences)2022，65，6： | 0 |
