查询词典 rational expression

This is the first report that not only the differences of flower symmetry genes expression but also expression timings may result to zygomorphy/actinomorphy transition.

本研究首次报导不仅对称基因表现位置，甚至时间也是关键性因素，因而促成残存两侧对称的变异型辐射对称花的形成。

Experiments show that Ang Ⅱ activates JNK mediated by AT〓, and JNK increases transcription activity of c-Jun by phosphorylating c-Jun amido-terminal, and induces expression of c-Fos gene. c-Jun and c-Fos form transcriptional factor activated protein-1 complex. AP-1 may stimulates genes which correlate with cardiovascular remodeling expression, such as transforming growth factor, collagen type Ⅰ and Ⅲ, skeletal muscle α-actin,β-MHC, atrial natriuretic factor.

实验表明，在心肌和血管平滑肌细胞Ang Ⅱ通过AT〓介导激活JNK；JNK通过磷酸化c-Jun氨基末端增加c-Jun的转录活性并诱导c-Fos基因表达，c-Jun和c-Fos蛋白形成转录因子复合物激活蛋白-1(AP-1)，并刺激各种心血管重塑相关基因如转化生长因子-β1(TGF-β1)、Ⅰ，Ⅲ型胶原、骨骼肌α-actin、β-MHC(β-myosin heavy chain，β-肌球蛋白重链)、心钠素的表达。

Active MAPKs translocate into nucleus and thus regulate gene expression. Now, three main parallel pathways of MAPK family have been discovered : ERK1/2, JNK and p38. They can induce different gene expression and thus cause different cell reaction.

现已发现MAPK家族主要有三条平行的信号转导通路：ERK1／2、JNK和p38，三条通路可以活化不同的转录因子，启动不同的基因表达，从而引发不同的细胞反应。

The level of ADAR gene expression was expressed as ratio expression rate of ADAR gene /β-actin acc...

ADAR3在正常人脑胶质细胞及苯乙酸处理前后的胶质瘤细胞中，均未见表达。结论ADAR2 mRNA水平高表达，可能与高恶性度胶质瘤的发生有关。

Objective To investigate the expression of cyclooxygenase-2(COX-2)and Survivin in the salivary adenoid cystic carcinomaand the relationship between their expression and the tumorigenesis and development.

目的 研究环氧化酶-2(cyclooxygenase-2， COX-2)与Survivin基因在涎腺腺样囊性癌中的表达及其与肿瘤发生发展的关系。

For instance, for the algebraic expression 4 + 4, an AddExpression class can be used to represent the expression.

例如，为代数表达式4 + 4，1 AddExpression类可以用来代表表达。

An algebraic or geometric expression from which another expression is derived.

原始的一种代数的或几何的表达，基于此派生出另一种表达

Mathematics being an algebraic or geometric expression from which another expression is derived.

指其他表达式是从中派生出来的代数或者几何表达式。

Write an algebraic expression for each verbal expression.

把每个文字表达式写成代数式。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
