| 1 | Comparative proteogenomic analysis of the Leptospira interrogans virulence-attenuated strain IPAV against the pathogenic strain 56601显示文摘稀释毒力的螺旋体 interrogans serovar Lai 紧张 IPAV 被延长实验室经过从在中国孤立的高度剧毒的祖先的紧张导出。我们学习了 IPAV 的基因变化对病原的 L 经由比较分析使它变为无毒害。interrogans serovar Lai 紧张 56601。IPAV 紧张的完全的染色体顺序决心、使用与作比较,然后修正并且重新注解紧张 56601 的染色体顺序。除了他们的高度类似的 genomic,结构和基因顺序, 33 插入的一个总数, 53 删除和 301 个单个核苷酸的变化(SNV ) 在整个直接影响 101 基因的 IPAV 的染色体被检测,在他们的 5 ′ 的任何一个;在上游的区域或在他们的编码区域以内。在他们之中, 44 功能的基因的多数涉及信号 transduction,压力反应, transmembrane 运输和氮新陈代谢。基于量的液体,层析(LC )-MS/MS 数据揭示了的比较 proteomic 分析在 orthologs 的 1 627 选择的对之中,在 IPAV 的 174 基因拉紧,这是 upregulated,与主要在精力的班上的丰富生产和类脂化合物新陈代谢。相反,在紧张 56601 的 228 基因是 upregulated,与在蛋白质翻译和 DNA 复制 / 修理的范畴充实的多数。 genomic 和 proteomic 途径的联合在批评基因说明了那改变的表情或变化,例如编码 Ser/Thr kinase ,碳饥饿蛋白质 CstA ,夫酸安合成酶,GTP有约束力的蛋白质 BipA , ribonucleotide-diphosphate reductase 和磷酸盐 transporter 的那些,并且在脂蛋白或外部膜蛋白质的翻译侧面的改变是可能的在紧张 IPAV 说明毒力变细。 | Yi Zhong Xiao Chang Xing-Jun Cao Yan Zhang Huajun Zheng Yongzhang Zhu Chengsong Cai Zelin Cui Yunyi Zhang Yuan-Yuan Li Xiu-Gao Jiang Guo-Ping Zhao Shengyue Wang Yixue Li Rong Zeng Xuan Li Xiao-Kui Guo | 2011 | Cell Research2011，21，8： | 10 |
| 2 | Analysis of the microbiota of sputum samples from patients with lower respiratory tract infections显示文摘唾沫是从患更低的呼吸的道感染的病人收集的最普通的样品,它为这些感染的细菌的鉴定是关键的。在这研究,我们与更低的呼吸的道感染从 101 个病人注册了 101 件唾沫样品。开始,在唾沫包含的细菌的 16S rDNA V3 hypervariable 区域的 pyrosequencing 为 microbiota 分析作为一条文化无关的途径被利用。为比较,用一个文化依赖者的临床的实验室测试为样品也被做的唾沫的一样的队自动化了细菌的鉴定系统。由 pyrosequencing, > 70,000 DNA 碎片在被 Ribosomal 数据库工程(RDP ) 过程分析以后被发现并且分类进 129 个细菌的类。大多数序列属于几个占优势的类,例如链球菌和葡萄球菌,显示这些类起在更低的呼吸的道感染的一个重要作用。另外,属于潜在的原因的代理人的一些序列例如霉浆菌, Haemophilus,和 Moraxella,也被发现,但是这些序列没被临床的实验室测试发现。为两个方法检测的九个类,方法的敏感被比较,结果证明 pyrosequencing 是更敏感的,除了 Klebsiella 和 Mycobacterium。显著地,这个方法揭示了更复杂的细菌的社区,它为细菌的察觉显示出一个有希望的能力。 | Yuhua Zhou Ping Lin Qingtian Li Lizhong Han Huajun Zheng Yanxia Wei Zelin Cui Yuxing Ni Xiaokui Guo | 2010 | Acta Biochimica et Biophysica Sinica2010，42，10： | 8 |
| 3 | New microbiota found in sputum from patients with community-acquired pneumonia显示文摘获得社区的肺病(帽子) 是医院和哪个还全身地没被讨论的细菌的社区里的一颗主要担心。从在尖锐阶段的病人的唾沫是反映它的特征的一种可存取的样品。在我们的学习,我们与帽子从 45 个病人分析了 45 件唾沫样品。从健康的人的十八件唾沫样品被选择为控制。在唾沫包含的所有细菌的 16 年代 rDNA V3 hypervariable 区域的 Pyrosequencing 被用作一个文化无关的方法揭示社区体质。另外,我们为在唾沫的获得医院的肺病(幸运) 的出版数据被用于比较。由 pyrosequencing, > 90,000 DNA 读被检测。在被工具在 Ribosomal 数据库工程分析以后, reads 被分类进五个主要的数并且 > 100 个类。在数水平,读的帽子的分发类似于健康的人并且在类水平的,每个类的出现在三个范畴拥有他们的特征。象链球菌和 Neisseria 那样的类在他们的百分比显示出稳定性,显示如此的类被外长的细菌或抗菌素很少影响。象在帽子的 Moraxella 和 Rothia 那样的另外的类的角色应该被强调。根据我们的分析,当时,帽子的细菌的社区与细微变化与那些相比健康的人,但是有在幸运之间的大差距。同时, Rothia 可能是一个重要内长的引起肺病的因素。 | Chunyan Chen Tian Shen Fei Tian Ping Lin Qingtian Li Zelin Cui Yajuan Zhang Min Xue Jing Ye Xiaokui Guo YuhuaZhou | 2013 | Acta Biochimica et Biophysica Sinica2013，45，12： | 3 |
| 4 | PUMD:a PU learning-based malicious domain detection framework显示文摘Domain name system(DNS),as one of the most critical internet infrastructure,has been abused by various cyber attacks.Current malicious domain detection capabilities are limited by insufficient credible label information,severe class imbalance,and incompact distribution of domain samples in different malicious activities.This paper proposes a malicious domain detection framework named PUMD,which innovatively introduces Positive and Unlabeled(PU)learning solution to solve the problem of insuffcient label information,adopts customized sample weight to improve the impact of class imbalance,and effectively constructs evidence features based on resource overlapping to reduce the intra-class distance of malicious samples.Besides,a feature selection strategy based on permutation importance and binning is proposed to screen the most informative detection features.Finally,we conduct experiments on the open source real DNS traffic dataset provided by QI-ANXIN Technology Group to evaluate the PUMD framework's abil-ity to capture potential command and control(C&C)domains for malicious activities.The experimental results prove that PUMD can achieve the best detection performance under different label frequencies and class imbalance ratios. | Zhaoshan Fan Qing Wang Haoran Jiao Junrong Liu Zelin Cui Song Liu Yuling Liu | 2023 | Cybersecurity2023，6，1： | 0 |
| 5 | Effects of Trawl Selectivity and Genetic Parameters on Fish Body Length Under Long-Term Trawling显示文摘Long-term fishing pressure affects the biological characteristics of exploited fish stocks. The biological characteristics of hairtail(Trichiurus lepturus) in the East China Sea are unable to recover because of long-term trawling. Fishing induces evolutionary effects on the fish's biological characteristics. Evidence of these changes includes small size at age, a shift to earlier age structure, and early maturation. Natural and artificial selection usually affect the fish's life history. Selection can induce different chances of reproduction, and individual fish can give a different genetic contribution to the next generation. In this study, analysis of time-dependent probability of significance and test of sensitivity were used to explore the effects of fish exploitation rate, mesh size, and heritability with long-term trawling. Results showed that fishing parameters were important drivers to exploited fish population. However, genetic traits altered by fishing were slow, and the changes in biological characteristics were weaker than those caused by fishing selection. Exploitation rate and mesh size exhibited similar evolutionary trend tendency under long-term fishing. The time-dependent probability of significance trend showed a gradual growth and tended to be stable. Therefore, the direction of fishing-induced evolution and successful management of fish species require considerable attention to contribute to sustainable fisheries in China. | YU Yang SUN Peng CUI He SHENG Huaxiang ZHAO Fenfang TANG Yanli CHEN Zelin | 2015 | Journal of Ocean University of China2015，14，5： | 0 |
