| 1 | Genetic and biological characteristics of the globally circulating H5N8 avian influenza viruses and the protective efficacy offered by the poultry vaccine currently used in China显示文摘The H5N8 avian influenza viruses have been widely circulating in wild birds and are responsible for the loss of over 33 million domestic poultry in Europe, Russia, Middle East, and Asia since January 2020. To monitor the invasion and spread of the H5N8 virus in China, we performed active surveillance by analyzing 317 wild bird samples and swab samples collected from 41,172 poultry all over the country. We isolated 22 H5N8 viruses from wild birds and 14 H5N8 viruses from waterfowls. Genetic analysis indicated that the 36 viruses formed two different genotypes: one genotype viruses were widely detected from different wild birds and domestic waterfowls;the other genotype was isolated from a whopper swan. We further revealed the origin and spatiotemporal spread of these two distinct H5N8 virus genotypes in 2020 and 2021. Animal studies indicated that the H5N8 isolates are highly pathogenic to chickens, mildly pathogenic in ducks, but have distinct pathotypes in mice. Moreover, we found that vaccinated poultry in China could be completely protected against H5N8 virus challenge. Given that the H5N8 viruses are likely to continue to spread in wild birds, vaccination of poultry is highly recommended in high-risk countries to prevent H5N8 avian influenza. | Pengfei Cui Xianying Zeng Xuyong Li Yanbing Li Jianzhong Shi Conghui Zhao Zhiyuan Qu Yanwen Wang Jing Guo Wenli Gu Qi Ma Yuancheng Zhang Weipeng Lin Minghui Li Jingman Tian Dongxue Wang Xin Xing Yanjing Liu Shuxin Pan Yaping Zhang Hongmei Bao Liling Liu Guobin Tian Chengjun Li Guohua Deng Hualan Chen | 2022 | Science China(Life Sciences)2022，65，4： | 12 |

| 6 | Dual-functional bacterial cellulose modified with phase-transitioned proteins and gold nanorods combining antifouling and photothermal bactericidal properties显示文摘Bacterial cellulose(BC)is one of the most versatile natural biopolymers with unique physical,chemical,and biological features.However,the lack of intrinsic antibacterial property of native BC limits its broad biomedical applications where such property is highly required to prevent contamination or infection caused by attached bacteria.In this work,we developed a simple and facile method to fabricate a dualfunctional BC membrane by physical incorporation of gold nanorods(GNRs)followed by deposition of a phase-transitioned bovine serum albumin(PTB)film.Due to the broad-spectrum antifouling property of the PTB film,the resulting membrane could prevent the adhesion and accumulation of bacteria.A few bacteria that broke through the protection of the PTB film could be eradicated under short-term irradiation of a near-infrared laser due to the excellent photothermal property of incorporated GNRs.The whole fabrication was conducted in a simple and environmentally friendly manner,avoiding complicated processes and toxic organic solvents.Moreover,because all the components were biocompatible,the resulting membrane showed negligible cytotoxicity in vitro and good histocompatibility in vivo.This work thus provided a reliable way to endow BC with antibacterial property,being beneficial for diverse biomedical applications. | Luohuizi Li Guize Li Yong Wu Yuancheng Lin Yangcui Qu Yan Wu Kunyan Lu Yi Zou Hong Chen Qian Yu Yanxia Zhang | 2022 | Journal of Materials Science & Technology2022，，15： | 0 |
| 7 | Rural Development Transformation and Social Governance from the Perspective of Specialization:A Case Study of Ruiling Village in Guangzhou City,China显示文摘The reorganization of the global production network and the increased mobility of urban-rural elements have accelerated the differentiation of rural spaces,resulting in a trend towards specialization in rural areas.This paper focuses on the concept of specialization,and takes a renowned bonsai specialized village in Guangzhou City,China as a typical case to explore its transformation and development process,action logic and coupling mechanism with the social governance.The results show that:1)the development of rural specialization in Ruiling Village is shaped by several key actors,such as local governments,grassroots organizations,villagers,social organizations,policies,markets and infrastructure.The transfer of these key actors and the reconstruction of actor-networks in different stages have an important influence on the transformation and realization of rural development goals.2)Through subjects-driven,organization management and resource connection,social governance supports the specialization of rural industrial organization,operation,technology and mode.The governance structure shifts from decentralization to networking,refinement and integration.A coupling community of social governance and specialization is created by the social governance system of‘local government-grassroots organizationseconomic cooperatives-villagers’,which links industries,industrial chains and cooperatives.3)Social governance integrates into the value chain extension process of rural specialized development with a central,multi-level organizational structure.It promotes the construction of the whole value chain through organizational planning,resource integration and image shaping,thus realizing the value,branding and organization of the industry,as well as the integration of rural sustainable development and governance mechanism.Social governance has a profound impact on the development of rural specialization in terms of subject,structure and mode,and participates in the construction of the whole value chain of rural areas.This paper provides a new perspective for understanding the coupling effect of social governance in the rural development transformation,and promotes the rural sustainable development and governance. | LIN Yuancheng YANG Ren LI Simeng | 2023 | Chinese Geographical Science2023，33，5： | 0 |
| 8 | Bacterial cellulose-based dressings with photothermal bactericidal activity and pro-angiogenic ability for infected wound healing显示文摘For most traditional wound dressings,it is challenging to simultaneously eliminate bacteria and promote angiogenesis to accelerate the healing process of bacteria-infected wounds.In this work,we develop a multifunctional dressing based on bacterial cellulose(BC)deposited with a tannic acid/Cu^(2+)ion/Mg^(2+)ion(TCM)complex film.Overall,the TCM complex exhibits robust interfacial adhesion to modify BC and good photothermal properties to effectively eradicate bacteria in the wound area under near-infrared(NIR)irradiation.The individual components of the TCM complex have several advantageous features for wound healing,such as antibacterial ability and negligible cytotoxicity;in particular,the released Cu^(2+)and Mg^(2+)ions are favorable for the proliferation,migration,and tube formation of endothelial cells in vitro.The results of in vivo experiments demonstrated that with the assistance of NIR irradiation,this composite dressing is more effective than traditional gauze or pristine BC dressing in promotion of angiogenesis and collagen deposition without causing remarkable inflammation,thereby accelerating the healing process of bacteria-infected full-thickness skin wounds.This work thus provides a simple and facile way to fabricate multifunctional BC-based dressings that could be potentially used for treating infected wounds. | Yan Wu Dongxu Jia Kunyan Lu Haixin Zhang Chunxia Liu Yuancheng Lin Jingjing Cheng Yi Zou Hu Xu Hong Chen Yanxia Zhang Qian Yu | 2023 | Journal of Materials Science & Technology2023，，29： | 0 |
| 9 | Microfluidic chemostatic bioreactor for high-throughput screening and sustainable co-harvesting of biomass and biodiesel in microalgae显示文摘As a renewable and sustainable source for energy,environment,and biomedical applications,microalgae and microalgal biodiesel have attracted great attention.However,their applications are confined due to the cost-efficiency of microalgal mass production.One-step strategy and continuous culturing systems could be solutions.However,current studies for optimization throughout microalgae-based biofuel production pipelines are generally derived from the batch culture process.Better tools are needed to study algal growth kinetics in continuous systems.A microfluidic chemostatic bioreactor was presented here,providing low-bioadhesive cultivations for algae in a cooperative environment of gas,nutrition,and temperature(GNT)involved with high throughput.The chip was used to mimic the continuous culture environment of bioreactors.It allowed simultaneously studying of 8×8 different chemostatic conditions on algal growth and oil production in parallel on a 7×7 cm^(2)footprint.On-chip experiments of batch and continuous cultures of Chlorella.sp.were performed to study growth and lipid accumulation under different nitrogen concentrations.The results demonstrated that microalgal cultures can be regulated to grow and accumulate lipids concurrently,thus enhancing lipid productivity in one step.The developed on-chip culturing condition screening,which was more suitable for continuous bioreactor,was achieved at a half shorter time,64-times higher throughput,and less reagent consumption.It could be used to establish chemostat cultures in continuous bioreactors which can dramatically accelerate the development of renewable and sustainable algal for CO_(2)fixation and biosynthesis and related systems for advanced sustainable energy,food,pharmacy,and agriculture with enormous social and ecological benefits. | Guoxia Zheng Yutong Cui Ling Lu Ming Guo Xuejun Hu Lin Wang Shuping Yu Shenxia Sun Yuancheng Li Xingcai Zhang Yunhua Wang | 2023 | Bioactive Materials2023，，7： | 0 |
| 10 | Superhydrophobic photothermal coatings based on candle soot for prevention of biofilm formation显示文摘Bacterial biofilms formed on the material surfaces have posed a series of serious problems for human health and industries.The treatment of mature biofilms is particularly difficult because they are inher-ently highly resistant against antibiotics and other adverse factors.The prevention is strategically advan-tageous over the treatment,and thus the development of innovative surfaces with capability to inhibit biofilm formation is highly demanded.In this work,we developed a superhydrophobic photothermal coating for prevention of biofilm formation,which was based on candle soot with hierarchical structure and excellent light-to-heat conversion ability.This coating was fabricated by deposition of a candle soot layer on the substrate,followed by sequential chemical vapor deposition of tetraethoxysilane and immo-bilization of fluorinated silane to make the coating robust and superhydrophobic.The resulted coating could repel a majority of bacteria from the surface at the early stage,and then eradicate a small number of bacteria remained on the surface under a short-term irradiation of near-infrared laser.The combi-nation of anti-adhesive property and photothermal bactericidal property endowed the coating with good antibiofilm property to prevent biofilm formation for at least 2 weeks.This coating is facile for deposition on various substrates with good storage stability,showing great potential for diverse practical applications to solve the biofilm-associated problems of materials and devices. | Yuancheng Lin Haixin Zhang Yi Zou Kunyan Lu Luohuizi Li Yan Wu Jingjing Cheng Yanxia Zhang Hong Chen Qian Yu | 2023 | Journal of Materials Science & Technology2023，，1： | 0 |
