After selecting a highly potent strain of poxvirus that was able to traffic to tumors when administered intravenously to mice the authors engineered the virus such that it would target only specific cancer cells -- those with increased expression of a protein known as E2F and/or activation of signaling downstream of a protein known as EGFR.

在选择高度特异性痘状病毒后才能有效的到达肿瘤生长地方，然后通过静脉途径给老鼠。这些病毒都是研究人员设计好的以至于只能到达特异性肿瘤细胞，像那些增加表达蛋白E2F和信号下游活化蛋白EGFR。

Cultivated at the early stage of the Neolithic Age,the morphological characters of plant opals of rice detected from the potsherds from the 3rd and 4th cultural layers of Hemudu and Luojiajiao site s,were analysed and compared.

对长江下游迄今为止发现的最古老的新石器时代遗址———河姆渡遗址、罗家角遗址进行了植物硅酸体分析，结果在两遗址出土的陶器碎片中发现了起源于水稻叶片运动细胞硅酸体。

Our results indicate that the RNA species may be regulated by PKC downstream signals related to the MAP kinase cascade. We observed E1 contains RNA increase in the polysome after induction of U937 differentiation.

我们分别对两者进行研究，发现含有Exon N1的Chk1 transcript可能以直接或间接的方式受p53的抑制；而含有Exon 1的Chk1 transcript的调控机制较不清楚，仅知可能是由PKC下游的讯息传递所调控，且可能和MAP kinase cascade有所关联。

The results show that the formation-ages of granitic plutons in the southern side of the Mayin'ebo fault in the researched area are (334.1±9.5) Ma,(300±9) Ma and (280±12) Ma with the initial 87Sr/86Sr ratios of 0.70433, 0.70435 and 0.70384, respectively, and that they were generated at different stages of middle-late Variscan Movement.

选取新疆东准噶尔北部青格里河下游一带鸟图布拉克、阿热勒托别和哈旦逊岩体等具一定规模的3个代表性岩体，通过全岩Rb-Sr等时线同位素定年，确定了研究区内玛音鄂博断裂南侧花岗岩类的形成时代分别为(334.1±9.5)Ma、(300±9)Ma和(280±12)Ma，其初始87Sr/86Sr比值分别为0.70433、0.70435和

Asian summer monsoon, one of the earth′s most energetic weather events, undoubtedly plays a key role in the variability of the general circulation. In this paper, through both calculation for the correlation coefficients between the monsoon indices and the geopotential height and the anomalous composite of the strong or weak ASM pentads, it is shown that the activity of the ASM...

本文通过夏季风指数与北半球环流的相关计算以及强、弱季风候北半球环流异常合成的分析发现，亚洲夏季风的活动会激发北半球夏季大气环流遥相关型，其主要相关中心均出现在季风区的下游地区，即从亚洲经太平洋至北美洲一带，除了表现出正负中心交替出现的波列状结构外，该遥相关型在太平洋地区还表现为一对南北向的偶极子异常型，我们将这一遥相关型称为亚洲太平洋北美型

Recent studies have shown that interaction parters can modulate the transcription activity of AP-2 over the downstream targets.

最近很多研究表明与AP-2相互作用的蛋白能够调节AP-2对下游基因的转录活性。

Downstream, paddlers will mix river camping with village stays in traditional rammed-earth homes.

到达下游，涉水者们将在河边露营或者在用传统方法筑成的乡村房屋中住宿。

The release height and downstream distance have been normalised using Hb.

释放高度和下游的距离已经正常化使用血红蛋白。

First, traders pushed up market prices, then push up the overall follow-up steel prices, pushing up the market, inventory costs, and interaction, the formation of steel prices pushed up the momentum, but the final release as a result of excessive steel production capacity, the downstream demand there is no substantial support, resulting in the second half of the last quarter-year of free-falling market prices of steel.

先是贸易商拉高市场价格，随后钢厂跟进推高整体出厂价格，推高市场库存成本，进而相互作用，形成钢材价格的推高的动力，但是最后由于钢厂无节制释放产能，下游需求没有实质性的支持，导致最后一季度下半旬钢材市场价格的自由落体。

But when I got to shore pap wasn't in sight yet, and as I was running her into a little creek like a gully, all hung over with vines and willows, I struck another idea: I judged I'd hide her good, and then,'stead of taking to the woods when I run off, I'd go down the river about fifty mile and camp in one place for good, and not have such a rough time tramping on foot.

不过我一上岸，不见爸爸的影子。我把小舟划到了一条类似溪沟的小河浜里，水面上挂满了藤萝和柳条，这时我心生一计。我断定，小舟我能藏好，不会有差错，等我出逃时，不必钻树林子了，不妨下到下游五十英里开外的去处，挑一个地方露营扎寨，免得靠双脚走，搞得累死累活的。

Do you know, i need you to come back

你知道吗，我需要你回来
