| 1 | Rhizospheric microbial communities are driven by Panax ginseng at different growth stages and biocontrol bacteria alleviates replanting mortality显示文摘The cultivation of Panax plants is hindered by replanting problems, which may be caused by plantdriven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased,whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as Luteolibacter, Cytophagaceae, Luteibacter, Sphingomonas,Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely,Brevundimonas, Enterobacteriaceae, Pandoraea, Cantharellales, Dendryphion, Fusarium, and Chytridiomycota,increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. Bacillus subtilis 50-1, a microbial antagonist against the pathogenic Fusarium oxysporum, was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and Fusarium abundance decreased by 63.3% and 46.1%, respectively, after inoculation with B. subtilis 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities;these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem. | Linlin Dong Jiang Xu Lianjuan Zhang Ruiyang Cheng Guangfei Wei He Su Juan Yang Jun Qian Ran Xu Shilin Chen | 2018 | Acta Pharmaceutica Sinica B2018，8，2： | 27 |
| 2 | A Review of Rotating Stall in Vaneless Diffuser of Centrifugal Compressor显示文摘At present, off-design centrifugal compressor suffers from great instabilities, such as rotating stall and surge, which lead to work failure, strong pressure fluctuations, and violent vibrations of the entire system. One cause of these instabilities is the rotating stall occurring in vaneless diffuser. In this review, recent researches on rotating stall of vaneless diffuser in centrifugal compressor are reviewed, and its inductive mechanism and characteristic description are emphatically introduced. In vaneless diffuser, the rotating stall starts up and fully develops under non-design conditions with the characteristic of increasing pressure fluctuation amplitude. The negative effects of rotating stall include reverse flow and vortex, both of which have significant effects on the instability of centrifugal compressors. Some improvement methods of rotating stall are also introduced, and a lot of examples are given. Finally, some suggestions and discussions are put forward for the future work. | ZHANG Lei HE Ruiyang WANG Songling ZHANG Qian | 2020 | Journal of Thermal Science2020，29，2： | 6 |
| 3 | An executable modeling and analyzing approach to C4ISR architecture显示文摘To analyze the behavioral model of the command,control,communication,computer,intelligence,surveillance,reconnaissance(C4ISR)architecture,we propose an executable modeling and analyzing approach to it.First,the meta concept model of the C4ISR architecture is introduced.According to the meta concept model,we construct the executable meta models of the C4ISR architecture by extending the meta models of fUML.Then,we define the concrete syntax and executable activity algebra(EAA)semantics for executable models.The semantics functions are introduced to translating the syntax description of executable models into the item of EAA.To support the execution of models,we propose the executable rules which are the structural operational semantics of EAA.Finally,an area air defense of the C4ISR system is used to illustrate the feasibility of the approach. | HE Hongyue ZHU Weixing LI Ruiyang DENG Qiaoyu | 2020 | Journal of Systems Engineering and Electronics2020，31，1： | 3 |
| 4 | LRP1 knockdown agravates lipopolysaccharide stimulated microglial and astrocytic neuroinflammatory responses by modulating TLR4/NF-κB/MAPKs signaling pathways显示文摘Neuroinflammation is an important pathological feature and an early event in the pathogenesis of Alzheimer's disease(AD),which is characterized by activation of microglia and astrocytes.Low-density lipoprotein receptor related protein 1(LRP1)is an endocytic receptor that is abundantly expressed in neurons,microglia,and astrocytes,and plays a critical role in AD pathogenesis.There is increasing evidence to show that LRP1 regulates inflammatory responses by modulating the release of pro-inflammatory cytokines and phagocytosis. | John Bosco Ruganzu Yingying He Xiaoqian Peng Hui Jin Xiangyuan Wu Chengheng Lin Ruiyang Ma Qian Liu Yihua Qian Weina Yang | 2021 | 解剖学杂志2021，44，S01： | 0 |
| 5 | A branch and price algorithm for the robust WSOS scheduling problem显示文摘To analyze and optimize the weapon system of systems(WSOS)scheduling process,a new method based on robust capabilities for WSOS scheduling optimization is proposed.First,we present an activity network to represent the military mission.The member systems need to be reasonably assigned to perform different activities in the mission.Then we express the problem as a set partitioning formulation with novel columns(activity flows).A heuristic branch-and-price algorithm is designed based on the model of the WSOS scheduling problem(WSOSSP).The algorithm uses the shortest resource-constrained path planning to generate robust activity flows that meet the capability requirements.Finally,we discuss this method in several test cases.The results show that the solution can reduce the makespan of the mission remarkably. | LI Ruiyang HE Ming HE Hongyue WANG Zhixue YANG Cheng | 2021 | Journal of Systems Engineering and Electronics2021，32，3： | 0 |
| 6 | Genomic,transcriptomic,and epigenomic analysis of a medicinal snake,Bungarus multicinctus,to provides insights into the origin of Elapidae neurotoxins显示文摘The many-banded krait,Bungarus multicinctus,has been recorded as the animal resource of JinQianBaiHuaShe in the Chinese Pharmacopoeia.Characterization of its venoms classified chief phyla of modern animal neurotoxins.However,the evolutionary origin and diversification of its neurotoxins as well as biosynthesis of its active compounds remain largely unknown due to the lack of its high-quality genome.Here,we present the 1.58 Gbp genome of B.multicinctus assembled into 18 chromosomes with contig/scaffold N50 of 7.53 Mbp/149.8 Mbp.Major bungarotoxin-coding genes were clustered within genome by family and found to be associated with ancient local duplications.The truncation of glycosylphosphatidylinositol anchor in the 3'-terminal of a LY6E paralog released modern three-finger toxins(3FTxs)from membrane tethering before the Colubroidea divergence.Subsequent expansion and mutations diversified and recruited these 3FTxs.After the cobra/krait divergence,the modern unit-B ofβ-bungarotoxin emerged with an extra cysteine residue.A subsequent point substitution in unit-A enabled theβ-bungarotoxin covalent linkage.The B.multicinctus gene expression,chromatin topological organization,and histone modification characteristics were featured by transcriptome,proteome,chromatin conformation capture sequencing,and ChIP-seq.The results highlighted that venom production was under a sophisticated regulation.Our findings provide new insights into snake neurotoxin research,meanwhile will facilitate antivenom development,toxin-driven drug discovery and the quality control of JinQianBaiHuaShe. | Jiang Xu Shuai Guo Xianmei Yin Mingqian Li He Su Xuejiao Liao Qiushi Li Liang Le Shiyu Chen Baosheng Liao Haoyu Hu Juan Lei Yingjie Zhu Xiaohui Qiu Lu Luo Jun Chen Ruiyang Cheng Zhenzhan Chang Han Zhang Nicholas Chieh Wu Yiming Guo Dianyun Hou Jin Pei Jihai Gao Yan Hua Zhihai Huang Shilin Chen | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 0 |
