RNA interference represents a common biological phenomenon of double-stranded RNA mediated post-transcriptional gene silencing, which lies in altitude plants and animals. The mechanism of this process is described as that: the dsRNA in cells are cut into double-stranded small interfering RNA. By joining with an effector complex termed RISC (RNA-induced silencing complex), siRNA binds to the cellular RNA with homologous sequences, and contributes to the degradation of the corresponding mRNA, the inhibition of specific gene expression.

RNAi技术是双链RNA(double strand RNA，dsRNA)介导的序列特异性的转录后基因沉默，广泛存在于高等植物和动物中，其机制是细胞内的dsRNA被Dicer剪切成双链的小分子干涉RNA (small interfering RNA，siRNA)与RNA诱导的基因沉默复合物结合，降解与之互补的靶mRNA，特异性抑制靶基因表达。

At the beginning, HLA class I/peptide complex teramer was prepared, including the most frequent alleles in Chinese, i.e., HLA-A2 and HLA-A24. Then the aAPCs were assembled by coating a cell-sized bead with pMHC and anti-CD28 antibody, which were able to provide the dual signals required for T cell activation, and used as stimulator to generate pMHC-specific CTL by co-culture with allogeneic peripheral blood lymphocyte.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
