| 1. | Virus particles differ in shape .
病毒颗粒有不同的形状。 |
| 2. | On entry into a cell, the virus particle uncoats .
进入细胞后，病毒颗粒就打开它的外壳。 |
| 3. | One side of a virus particle affixes itself to the surface of one cell .
病毒颗粒的一边粘附在一个细胞的表面。 |
| 4. | An investigation of sars virus particles ' spreading using computational fluid dynamics method
用计算流体力学方法研究非典型肺炎病毒颗粒的分布 |
| 5. | This means that recently vaccinated people excrete live virus particles from the vaccine ; but it is a less - dangerous strain of the virus
这意味着，最近接种的这批人排出了源自疫苗的危险性低的活病毒。 |
| 6. | Please remember that even though the virus has been found in other body fluids , the virus particle count has been too low to cause infection
请记住，虽然在其他体液中也发现了病毒，但它们的数量太少，不足以造成感染。 |
| 7. | An important goal is developing the ability to prepare liposomes of maximum size 100 nm to allow exclusion of most virus particles
技术发展的一个重要目标是制造最大为100纳米微脂粒，使其便于从大多数病毒微粒中分离出来。 |
| 8. | Some complicated molecules such as genetic engineered antibodies and virus particles for gene therapy can only be produced in mammalian cells
对于较复杂的分子如基因工程抗体，以及基因治疗用病毒载体，哺乳动物细胞更是首选的表达宿主。 |
| 9. | The env protein deduced from env gene encodes the hydrophilic surface protein ( su ) and the hydrophobic transmembrane domain ( tm ) that determine the specific interaction between virus particles and cell surface receptors during retroviral entry . the su of retroviruses is a highly variable genetic element , containing receptor binding sites and major antigenic determinants . exjsrv - specific dna probes were derived . by using these dna probes in tissue hybridization . we successfully identified jsrv mrna expression and proviruses dna in sheep lung tissues infected with jsrv and control group has no postive signals , validating the use of exogenous virus - specific dna probes in the analysis of oncogenic proviral integration sites and identification of integrated exogenous proviral sequences
用地高辛随机引物法标记exjsrv特异的env片段，制备探针，原位杂交检测spa肺组织中的rna及前病毒dna ，结果表明spa患羊肺组织内有jsrvenv基因mrna的表达，同时也检测到了前病毒dna ，而相应的阴性对照却无阳性信号，证实外源性病毒特异的dna探针在致瘤性前病毒的整合位点和整合的外源性前病毒的检测中具有可信度。 |
| 10. | As an important innate immune system , and as an important arm of the humoral immune response , the complement system is immediately ready to target and eliminate virus particles , to lysis those virions that have lipoprotein membranes , or to prevent it from entering host cells , or to marker them for destruction by other branch of the immune response . at the same time , the host normal tissue are protected from damaging by complement through recognizing the regulators of complement activation ( rca ) expressed on self cells
作为机体重要的天然免疫防御系统及特异性体液免疫应答的重要效应系统，补体系统除了具有溶解、清除病毒等致病微生物，阻止病毒进入靶细胞，调理病毒的吞噬等重要功能外，还可通过“识别”自身组织细胞表面的补体活化调节蛋白来对自身细胞加以保护，使之不受侵害。 |
