| 1 | 2019新型冠状病毒基因组特征和流行病学:病毒起源和受体结合的意义显示文摘研究者对来自9例新型冠状病毒肺炎住院患者的支气管肺泡灌洗液样本和培养的分离株进行了下一代测序。从这些个体中获得了严重急性呼吸综合征-冠状病毒2(severe acute respiratory syndrome-coronavirus 2,SARS-CoV-2)的完整和部分基因组序列。利用Sanger测序连接病毒重叠群以获得全长基因组,cDNA末端快速扩增确定终端区。对这些SARSCoV-2基因组和其他冠状病毒基因组进行了系统进化分析,以确定该病毒的进化史并有助于推断其可能的起源。 | 刘青(译) 刘莉(审校) Lu R Zhao X Li J Niu P Yang B Wu H Wang W Song H Huang B Zhu N Bi Y Ma X Zhan F Wang L Hu T Zhou H Hu Z Zhou W Zhao L Chen J Meng Y Wang J Lin Y Yuan J Xie Z Ma J Liu WJ Wang D Xu W Holmes EC Gao GF Wu G Chen W Shi W Tan W | 2020 | 中华高血压杂志2020，28，3： | 516 |
| 2 | 全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。 | Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A | 2016 | 饲料博览2016，0，12： | 2 |
| 3 | 纳米光子结构软膜紫外光固化纳米压印(英文)显示文摘紫外光固化纳米压印是实现纳米结构批量复制的一种新技术.其特点是低成本和高分辨,而且可以达到极高的套刻精度.为了得到大面积图案的均匀复制,可用聚二甲基硅氧烷(PDMS)制备透光的压印软模板.其母版图案可由高分辨率电子束曝光和反应离子刻蚀的方法在硅片基底上获得,然后用浇注的方法将图案转移到PDMS上.本实验特别发展了紫外光固化纳米压印适用于软膜压印的双层膜图型转移技术.该双层膜由廉价的光胶和聚甲基丙烯酸甲脂(PMMA)构成.对光胶层的压印可用普通的光学曝光仪实现.然后再将图案用反应离子刻蚀的方法转移到PMMA层中.为了证明方案的可行性,在两种不同材料的半导体基片上压印了三角晶格的光子晶体和准晶结构的图案,并用剥离的方法将它们转移到金属薄膜上,最后成功地进行了硅片刻蚀实验.相信这一纳米制做方法对大面积纳米光子结构和光学集成芯片的制造是普遍适用的. | SHI J WANG Z M BAO K PEROZ C BELOTTI M XU L P LUO C X SUN M H ZHANG B JI H OUYANG Q CHEN Y | 2006 | 纳米技术与精密工程2006，4，3： | 2 |

| 5 | Laser patterning for the study of MSC cardiogenic differentiation at the single-cell level显示文摘Mesenchymal stem cells(MSCs)have been cited as contributors to heart repair through cardiogenic differentiation and multiple cellular interactions,including the paracrine effect,cell fusion,and mechanical and electrical couplings.Due to heart–muscle complexity,progress in the development of knowledge concerning the role of MSCs in cardiac repair is heavily based on MSC–cardiomyocyte coculture.In conventional coculture systems,however,the in vivo cardiac muscle structure,in which rod-shaped cells are connected end-to-end,is not sustained;instead,irregularly shaped cells spread randomly,resulting in randomly distributed cell junctions.Consequently,contact-mediated cell–cell interactions(e.g.,the electrical triggering signal and the mechanical contraction wave that propagate through MSC–cardiomyocyte junctions)occur randomly.Thus,the data generated on the beneficial effects of MSCs may be irrelevant to in vivo biological processes.In this study,we explored whether cardiomyocyte alignment,the most important phenotype,is relevant to stem cell cardiogenic differentiation.Here,we report(i)the construction of a laser-patterned,biochip-based,stem cell–cardiomyocyte coculture model with controlled cell alignment;and(ii)single-cell-level data on stem cell cardiogenic differentiation under in vivo-like cardiomyocyte alignment conditions. | Zhen Ma Qiuying Liu Huaxiao Yang Raymond B Runyan Carol A Eisenberg Meifeng Xu Thomas K Borg Roger Markwald Yifei Wang Bruce Z Gao | 2013 | Light(Science & Applications)2013，2，1： | 2 |
