| 1 | A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s). | QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China | 2003 | Chinese Science Bulletin2003,48,10: | 121 |
| 2 | Effects of dietary protein/energy ratio on growth performance,carcass trait,meat quality,and plasma metabolites in pigs of different genotypes显示文摘Background:The protein/energy ratio is important for the production performance and utilization of available feed resources by animals.Increased protein consumption by mammals leads to elevated feed costs and increased nitrogen release into the environment.This study aimed to evaluate the effects of dietary protein/energy ratio on the growth performance,carcass traits,meat quality,and plasma metabolites of pigs of different genotypes.Methods:Bama mini-pigs and Landrace pigs were randomly assigned to two dietary treatment groups(Chinese conventional diet with low protein/energy ratio or National Research Council diet with high protein/energy ratio;n = 24 per treatment) in a 2x2 factorial arrangement.Blood and muscle samples were collected at the end of the nursery,growing,and finishing phases.Results:We observed significant interactions(P< 0.05) between breed and diet for total fat percentage,intramuscular fat(IMF) content,protein content in biceps femoris(BF) muscle,and plasma urea nitrogen(UN) concentration in the nursery phase;for average daily gain(ADG),average daily feed intake(ADFI),dry matter,IMF content in psoas major(PM) muscle,and plasma total protein and albumin concentrations in the growing phase;and for drip loss and plasma UN concentration in the finishing phase.Breed influenced(P < 0.05) growth performance,carcass traits,and meat quality,but not plasma metabolites.Throughout the trial,Landrace pigs showed significantly higher(P < 0.05) ADG,ADFI,dressing percentage,lean mass rate,and loin-eye area than did Bama mini-pigs,but significantly lower(P< 0.05)feed/gain ratio,fat percentage,backfat thickness,and IMF content.Dietary protein/energy ratio influenced the pH value,chemical composition of BF and PM muscles,and plasma activities of glutamic-pyruvic transaminase and gamma-glutamyl transpeptidase,and plasma concentration of UN.Conclusions:Compared with Landrace pigs,Bama mini-pigs showed slower growth and lower carcass performance,but had better meat quality.Moreover,unlike Landrace pigs,the dietary protein/energy ratio did not affect the growth performance of Bama mini-pigs.These results suggest that,in swine production,low dietary protein/energy ratio may be useful for reducing feed costs and minimizing the adverse effects of ammonia release into the environment. | Yingying Liu Xiangfeng Kong Guoli Jiang Bi'e Tan Jinping Deng Xiaojian Yang Fengna Li Xia Xiong Yulong Yin | 2015 | Journal of Animal Science and Biotechnology2015,6,4: | 37 |
| 3 | On the Application of PCA Technique to Fault Diagnosis显示文摘In this paper, we briefly address the application of the standard principal component analysis (PCA) technique to fault detection and identification. Based on an analysis of the existing test statistic, we propose a new test statistic, which is similar to the Hawkin’s TH 2 statistic but without the numerical drawback. In comparison with the SPE index, the threshold setting associated with the new statistic is computationally simpler. Our further study is dedicated to the analysis of fault sensitivity. We consider the off-set and scaling faults, and evaluate the test statistic by viewing its sensitivity to the faults. Our final study focuses on identifying off-set and scaling faults. To this end, two algorithms are proposed. This paper also includes some critical remarks on the application of the PCA technique to fault diagnosis. | DING S ZHANG P DING E YIN S Naik A DENG P GUI W | 2010 | Tsinghua Science and Technology2010,15,2: | 31 |
| 4 | 柑桔黄龙病的鉴定和柯赫氏定理(英文)显示文摘黄龙(梢)病被认为是世界柑橘生产上的毁灭性病害已超过一个世纪,但该病害的病原学至今还没有清晰地建立起来。根据16S rRNA基因序列分析,一组被称为'Candidatus Liberibacter species'的难培养细菌被认为与黄龙病相关。然而,要确定'Ca.Liberibacter spp.'是黄龙病病原的柯赫氏定理并没有真正完成。令我们担忧的是,近年来有些文献频频指出'Ca.Liberibacter spp.'是黄龙病的病原,其实该细菌与柑橘寄主的直接病理反应还没有完全确定。我们建议,在黄龙病病原学清楚之前,文献报道在这方面需要有准确的阐述。 | Chen J Deng X Civerolo E L Lee R F Jones J B Zhou C Hartung J S Manjunath K L Brlansky R H | 2011 | 植物病理学报2011,41,2: | 10 |
| 5 | SF_6断路器的热开断性能的数值预测(英文)显示文摘The design technology for HV SF6 gas circuit breakers is very demanding.A numerical method for prediction of the thermal interruption capability of SF6 gas circuit breakers is established based on the two-dimensional magneto-hydrodynamic(MHD) model and a commercial CFD(computational fluid dynamics) software,FLUENT.Nozzle ablation effect is considered by introducing an independent mass conservation equation for the ablated material to the overall conservation equations of mass,momentum,and energy.The ohmic heating and the radiation of the electric arc are considered in the model by adding relevant source terms.To predict the thermal interruption capability,the arc conductance 200 ns before current zero is used as an indicator.The CFD model is applied for the high current arcing phase,and Mayr arc model is used near the current zero period.The arc conductance at 200 ns before current zero(G200) for various arcing periods are computed by the present method.It shows that there exist a limit of the G200.For those whose arcing periods are within the arcing window,the related G200 are below the limit,therefore result a successful current interruption,and vice versa.The validation of the developed computer simulation tool is therefore verified.The numerical prediction by the simulation tool is verified by the direct interrupting test of 550 kV gas circuit breaker(GCB).The developed computer simulation tool was applied in the design of a 550 kV GCB.Significant benefits have been achieved in terms of both the cost saving and shorten of the development cycle. | MU Jingwei GUO Jin DENG Xiang'e | 2013 | 高电压技术2013,39,4: | 6 |
| 6 | The m^(6)A methylome of SARS-CoV-2 in host cells显示文摘The newly identified Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2)has resulted in a global health emergency because of its rapid spread and high mortality.The molecular mechanism of interaction between host and viral genomic RNA is yet unclear.We demonstrate herein that SARS-CoV-2 genomic RNA,as well as the negative-sense RNA,is dynamically N6-methyladenosine(m^(6)A)-modified in human and monkey cells.Combined RIP-seq and miCLIP analyses identified a total of 8 m^(6)A sites at single-base resolution in the genome.Especially,epidemic strains with mutations at these identified m^(6)A sites have emerged worldwide,and formed a unique cluster in the US as indicated by phylogenetic analysis.Further functional experiments showed that m^(6)A methylation negatively regulates SARS-CoV-2 infection.SARS-CoV-2 infection also triggered a global increase in host m^(6)A methylome,exhibiting altered localization and motifs of m^(6)A methylation in mRNAs.Altogether,our results identify m^(6)A as a dynamic epitranscriptomic mark mediating the virus–host interaction. | Jun’e Liu Yan-Peng Xu Kai Li Qing Ye Hang-Yu Zhou Hanxiao Sun Xiaoyu Li Liu Yu Yong-Qiang Deng Rui-Ting Li Meng-Li Cheng Bo He Jia Zhou Xiao-Feng Li Aiping Wu Chengqi Yi Cheng-Feng Qin | 2021 | Cell Research2021,31,4: | 5 |

| 8 | OsbZIP76 interacts with OsNF-YBs and regulates endosperm cellularization in rice (Oryza sativa)显示文摘Following double fertilization,plant endosperm nuclei undergo syncytial divisions,followed by synchro-nous cellularization.Cellularization is a key event during endosperm development,but our understanding of its regulation is limited to Arabidopsis.In this study we show that OsbZIP76 regulates cellularization in rice(Oryza sativa).Activation of OsbZIP76 coincided with the initiation of cellularization,and its knockdown or knockout mutants exhibited precocious cellularization.Genes involved in en-dosperm development or starch biosynthesis were pre-maturely activated in the osbzip76 caryopsis.As a putative transcription factor,OsbZIP76 alone lacked transcriptional activation activity;however,it interacted with the nuclear factor Y(NF-Y)family transcription factors OsNF-YB9 and OsNF-YB1 in yeast and in planta.OsbZIP76 and OsNF-YB9 were predominantly expressed in the endosperm and the proteins colocalized.Seeds of osnf-yb1 and osbzip76 mu-tants showed reduced size and reduced apparent amylose content.The parent-of-origin-dependent expression of OsbZIP76 is variable in different rice accessions.In sum-mary,OsbZIP76 is an endosperm-expressed imprinted gene that regulates endosperm development in rice. | Baixiao Niu Hui Deng Tingting Li Sandeep Sharma Qianbin Yun Qianru Li Zhiguo E Chen Chen | 2020 | Journal of Integrative Plant Biology2020,62,12: | 4 |

| 10 | Oral delivery of capsaicin using MPEG-PC nanoparticles显示文摘Aim: To prepare a biodegradable polymeric carrier for oral delivery of a water-insoluble drug capsaicin (CAP) and evaluate its quality. Methods: CAP-loaded methoxy poly (ethylene glycol)-poly(c-caprolactone) nanoparticles (CAP/NPs) were prepared using a modified emulsification solvent diffusion technique. The quality of CAP/NPs were evaluated using transmission electron microscopy, powder X-ray diffraction, differential scanning calorimetry and Fourier transform infrared techniques. A dialysis method was used to analyze the in vitro release profile of CAP from the CAP/NPs. Adult male rats were orally administered CAP/NPs (35 mg/kg); and the plasma concentrations of CAP were measured with a validated HPLC method. The morphology of rat gastric mucosa was studied with HE staining. Results: CAP/NPs had an average diameter of 82.54±0.51 nm, high drug-loading capacity of 14.0%±0.13% and high stability. CAP/NPs showed a biphasic release profile in vitro: the burst release was less than 25% of the loaded drug within 12 h followed by a more sustained release for 60 h. The pharmacokinetics study showed that the mean maximum plasma concentration was observed 4 h after oral administered of CAP/NPs, and approximately 90 ng/mL of CAP was detected in serum after 36 h. The area under the curve for the CAP/NPs group was approximately 6-fold higher than that for raw CAP suspension. Histological studies showed that CAP/NPs markedly reduced CAP-caused gastric mucosa irritation. Conclusion: CAP/NPs significantly enhance the bioavailability of CAP and markedly reduce gastric mucosa irritation in rats. | Wei PENG Xin-yi JIANG Yuan ZHU E Omari-Siaw Wen-wen DENG Jiang-nan YU Xi-ming XU Wei-ming ZHANG | 2015 | Acta Pharmacologica Sinica2015,36,1: | 2 |
| 11 | Natural variation of H3K27me3 modification in two Arabidopsis accessions and their hybrid显示文摘Histone modifications affect gene expression, but hthe mechanism and biological consequence of natural variation igin histone modifications remain unclear. Here, we generated Hgenome-wide integrated maps of H3K27me3 modification and transcriptome for Col, C24 and their F1 hybrid. A total of 1,828 genomic regions showing variation in H3K27me3 modification between Col and C24 were identified, most of which were associated with genic regions. Natural variation of H3K27me3 modification between parents could result in allelic bias of H3K27me3 in hybrids. Furthermore, we found that H3K27me3 variation between Col and C24 was negatively correlated with gene expression differences between two accessions, especially with those arising from the cis-effect. Importantly,mutation of CLF, an Arabidopsis methyltransferase for H3K27,altered gene expression patterns between the parents.Together, these data provide insights into natural variation of histone modifications and their association with gene expression differences between Arabidopsis ecotypes. | Mei Yang Xuncheng Wang Hao Huang Diqiu Ren Yan'e Su Pan Zhu Danmeng Zhu Liumin Fan Liangbi Chen Guangming He Xing Wang Deng | 2016 | Journal of Integrative Plant Biology2016,58,5: | 2 |
