The dose-dependent experiment revealed that Id1 antagonised E47 and Ets1 mediated transcriptional activation in a dose-dependent manner. With pGL3-870 as a template, site-directed mutagenesis of E-box and / or ETS-binding site was introduced into p16 promoter. E47 could not activate the transcription of p16 promoter with E-boxes mutated, and Ets1 could not activate the transcription of p16 promoter with EBS mutated. The synergy effect between E47 and Ets1 would occur only if the E-boxes and EBS were present. These facts demonstrated that E47 and Ets1 proteins were not recruited to the promoter by binding to other cis-elements or through interaction with other protein factors, however, they bound to DNA directly through respective consensus sequences in p16 promoter.

以pGL3-870为模板，构建了E-box或/和EBS点突变的p16启动子报告基因载体，将野生型和突变型的报告载体分别与pI-E47、pI-Etsl以及pI-E47+pI-Ets1共转染，发现E47和Ets1所诱导的转录激活作用依赖于启动子DNA上存在的各自的特异结合序列，二者的协同作用也只有当两个结合位点都存在时才会发生，说明E47和Ets1不是与其它作用元件或其它蛋白质因子相作用而被招募到该启动子的，它们是通过启动子上各自的特异结合位点与DNA直接结合的。

The cultured RPE cells were divided into 3 groups: normal control group, experimental group(blue light for 40 minutes) and vitamin E group(blue light+100μM vitamin E).

视网膜色素上皮细胞分为 3组：正常组，实验组(蓝光照射 40 min)，维生素 E组(蓝光照射同时给予维生素 E)。

Finally, new, compact millimeter-wave diplexers which employ cross-coupled E-plane filters and E-plane filters with over-moded cavities are analysed.

最后，设计了使用E面交叉耦合滤波器和E面多模腔滤波器的构成的紧凑结构毫米波双工器。

Influence of the antioxidants vitamin E and idebenone on retinal cell injury mediated by chemical ischemia, hypoglycemia, or oxidative stressRego A, SantosM, Oliveira C.. Free Radic. Biol. Med, 1999, 26: 1405 - 1417Abstract:A role for the antioxidants vitamin E and idebenone in decreasing retinal cell injury, after metabolic inhibition induced by chemical ischemia and hypoglycemia, was investigated and compared with oxidative stress conditions.

对由于化学贫血与低血糖所引起的代谢抑制后，抗氧化剂维生素E与艾地苯醌视网膜细胞受损所引起的作用进行了研究，同时并与氧化应激情况进行了对比，对氧化物维生素E(20 microM)和艾地苯醌(10 microM)进行先期培养可以在氧化应激或低血糖后防止视网膜细胞受损，而对上述二种抗氧化剂给予预先培养后带来的保护作用则有所减低。

The ratio of final baryon to meson and baryon antibaryon correlation in e +e - annihilation are considered as sensitive observables to test the hadronizition models,because among the results obtainted in different popular hadronizition models,only those from JETSET event generator can fit experimental data by adjusting extra ad hoc parameters.

在e+e-→h′s反应中，末态重子介子比及重子反重子关联，在流行的强子化模型中，仅有JETSET事件发生器能通过调节专用附加参数较好拟合实验，被认为是检验强子化模型的最敏感可观察量。

In view of the fact that the sporadic E clouds occur at around the same height as the E layer, similar distances are achieved.

由于事实分散E 云彩和E 层数一样发生在高度前后，相似的距离达到。
