| 1. | This charge is reduced by digestion with neuraminidase .
这一电荷被唾液酸苷酶消化而降低。 |
| 2. | With the neuraminidase enzyme shackled , the virus has difficulty spreading to and infecting other cells
只要神经胺酸酶遭到了限制，病毒也就难以散布并侵犯其他细胞，也因此可以缩短感冒发作的期间。 |
| 3. | The x - ray structure of wildtype tern n9 influenza virus neuraminidase ( 2qwk ) shown with five ligands generated using rachel that are predicted to be active
由一个配基/受体出发, rachel通过系统化修改配基上用户定义位点对配体进行自动的组合优化。 |
| 4. | Injection of rats with neuraminidase , however , resulted in a major increase of urinary albumin and was associated with an increase in urinary free neuraminic acid
然而给大鼠注射神经氨酸酶却可以使尿白蛋白大量增加，并伴有尿液游离神经氨酸增加。 |
| 5. | Three types of influenza viruses are recognized : a , b and c . influenza a viruses are further categorized into subtypes on the basis of two surface antigens : haemagglutinin and neuraminidase
流感病毒共分甲乙丙型三种。甲型流感可依据病毒表面的血凝素haemagglutinin ，即h及神经胺酸neuraminidase ，即n两种抗原类型，再细分为不同的亚型。 |
| 6. | Three types of influenza viruses are recognised : a , b and c . influenza a viruses are further categorised into subtypes on the basis of two surfaces antigens : haemagglutinin and neuraminidase
流感病毒共分甲乙丙型三种。甲型流感可依据病毒表面的血凝素haemagglutinin ，即h及神经胺酸neuraminidase ，即n两种抗原类型，再细分为不同的亚型。 |
| 7. | In this study five recombinant plasmids containing hn ( hemagglutinin - neuraminidase ) genes of ndv ( newcastle disease virus ) were constructed , hn genes were amplified by reverse transcriptase - polymerase chain reaction ( rt - pcr ) and were inserted directly into eukaryotic expression plasmid pcdna3
应用反转录-聚合酶链反应( rt - pcr )获得两株新城疫病毒( ndv )血凝素-神经氨酸酶( hn )基因cdna ，然后定向插入真核表达质粒pcdna3中，构建了含hn基因的重组质粒。 |
| 8. | A surface antigen hemagglutinin - neuraminidase ( hn ) gene of the ndv b95 strain , was selected to study as target gene . referred to the reported sequence , rwo primers were designed and synthesized . hn gene of ndv b95 strain was amplified by rt - pcr , the pcr products were checked by agrose gel electrophoresis and purified by agrose gel fraction method
为此，从澳大利亚某大学兽医病理系引进一株ndv热稳定性天然弱毒b95株，并选取其表面抗原血凝素?神经氨酸酶的编码基因为目的基因，根据国外已发表的序列，设计一对引物，利用rt - pcr技术扩增出了ndvb95株hn基因。 |
| 9. | The fusion ( f ) protein and hemagglutinin - neuraminidase ( hn ) are the major virulence factors of the virus to which the host responds well with protective antibody production . recombinant plasmids containing the f or hn gene can induce specific immune responses against ndv . however , dna vaccination by injection or gene gun routes is rather inconvenient and costly in field applications in scaled animal farms
融合蛋白( f )和血凝素-神经氨酸酶蛋白( hn )是ndv的主要宿主保护性抗原，以f基因和hn基因为免疫原研制的dna疫苗能诱导一定程度的免疫应答，但注射免疫或基因枪免疫途径因实际操作和成本等问题难以推广应用，而直接口服重组质粒dna免疫效果不理想。 |
