| 1. | Phenotyping of progenies derived from pharbiti nil mutant 裂叶牵牛花色变异株后代的表型分析 |
| 2. | Separation on a new antigenic drift strain a3 of influenza viruses in guizhou 贵州省分离出一株甲3型流感病毒新变异株 |
| 3. | 《 international hepatis 》 : what is the main influential factor in drug - resistance variant 《国际肝病》 : .什么是耐药变异株的主要影响因素? |
| 4. | With vvibdv and variant strains showed , it is very important to research of antigen and virulence of ibdv 随着vvibdv和变异株的发现, ibdv的抗原变异和毒力研究变的尤为重要。 |
| 5. | Substitution and insertion in all strains si gene , the homogeneity of nucleotide and the deduced amino acids of s1 gene with 17 alien and domestic references strains were equally less than 80 % S1基因除与qx的亲缘关系较近外,与其它参考株的同源率均低于80 ,可能为一株国内流行性的变异株。 |
| 6. | A 59 - year - old man receiving long - term lamivudine therapy experienced a fatal exacerbation of hepatitis b virus ( hbv ) infection resulting in hepatic necrosis following the emergence of variant hbv 一例长期使用拉米夫定治疗的59岁男性患者在hbv变异株出现后乙肝病毒感染发生致命性加重,导致肝坏死。 |
| 7. | The traditional inactivated or attenuated vaccines could not provide enough protection against these variants and wibdv . therefore , a new generation of more effective and safer vaccines is anticipated . the purpose of this study was to develop a dna vaccine against ibdv 用弱毒苗和灭活苗免疫鸡群是目前防治ibd的主要方法,但随着ibdv变异株与超强毒株的出现,免疫失败常有发生。 |
| 8. | Two variant lines , named by tc243 - 1 and tc243 - 2 , had been obtained and their variant traits had been steadily inherited to t5 . the query to nasc suggested that tc243 - 1 and tc243 - 2 were new mutants . the molecular analysis of transferred plants and their offspring was carried out from the following four aspects 在离子束介导红甜菜转化后代中筛选到两个稳定变异株系tc243 - 1和tc243 - 2 ,经与拟南芥菜突变体库比较,确认为新的变异类型。 |
