查询词典 interference phenomenon

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。

Fresnel thought that the light vibration is one continuous medium- by condition mechanical elastic vibration, he supplemented the huygens' principle by the Young interference principle in 1835, from this has had the Huygens - Fresnel principle which is familiar by people, with this principle can either completely explain the light straight line dissemination,or can discuss the diffraction phenomenon,and it becomes a important principle in the wave optics.

菲涅耳认为光振动是一种连续介质-以态的机械弹性振动，他于1835年以杨氏干涉原理补充了惠更斯原理，由此产生了今天人们所熟知的惠更斯-菲涅耳原理，用这个原理既能圆满地解释光的直线传播，也能讨论衍射现象，成为波动光学中的重要原理。

Furthermore, the brain area of anterior cingulated cortex revealed different response type under emotional and non-emotional interference condition, i.e, activation of ACC in color-word Stroop task was enhanced along with increasing of cognitive conflicting interference. Yet in emotional Stroop task, activation of ACC is reduced when the negative emotional interference was enhanced. This phenomenon suggests that ACC possess a flexible conflict monitoring mechanism and adaptive mechanism, thus providing evidence for the theory that ACC plays an important role in the cognitive and emotional interaction.

其结果显示，背侧前额叶、前扣带回是共同参与情绪与非情绪干扰的执行抑制的脑区，其中，前扣带回在情绪与非情绪干扰两种条件下出现不同类型的反应方式，即前扣带回在色字Stroop作业中随认知冲突干扰梯度的增加而增加，但在情绪Stroop作业中随负性情绪干扰梯度的增加而减少，体现出前扣带回具有灵活的冲突监控与适应性机能，支持前扣带回在认知与情绪交互作用中扮演重要角色的理论。
