By phenotype observation, combined with root tipchromosome counting, PMC MI pairing analysis and chromosome C-banding, a ditelosomic addition line 94K227 and a disomic addition line 94K280 was identified among BC2F2 and BC2F3 population respectively.C-banding results showed that 94K227 contains 1 pair of long arms in chromosome B, and 94K280 contains 1 pair of chromosome D from R.

用普通小麦-纤毛鹅观草双倍体与普通小麦中国春连续回交两次，然后连续自交，通过形态观察、根尖细胞染色体计数、花粉母细胞减数分裂中期Ⅰ染色体配对分析及染色体C－分带，在BC2F3和BC2F3群体中，分别筛选到一个端二体异附加系94K227和一个二体异附加系94K280，其中C-分带显示94K227添加的是纤毛鹅观草染色体B的一对长臂， 94K280添加的是纤毛鹅观草的一对染色体D。

The acyl derivatives all exhibited higher inhibitory effect than prinsepiol, among which isobutyryl and diacetate derivatives exhibited highest activity with EC50 of 3.85 mg/L and 5.60 mg/L respectively.

在Prinsepiol 4，4'位引入不同酰基后化合物的抑菌活性均有不同程度提高，其中4，4'-二异丁酰基衍生物和4，4'-二乙酰基衍生物的抑菌活性均较好，有效中浓度(EC50)分别为3.85和5.60 mg/L，是Prinsepiol的6~8倍。

In this study, isobaric tags for relative and absolute quantification labeling coupled with two-dimensional liquid chromatography-tandem mass spectrometry (2D-LC-MS/MS) was employed to compare the differential protein expressions in MCF7 cells upon 17β-oestradiol (E2) stimulation or serum deprivation versus in normal conditions. A total of 576 proteins with the confidential level of ≥95% were identified, 26 proteins among the 576 proteins were found to be differentially expressed after E2 stimulation or serum deprivation, and among them 10 proteins were up-regulated and 16 proteins were down-regulated by more than two folds.

利用四重用于相对和绝对定量的等量异位标签(isobaric tags for relative and absolute quantification， iTRAQ)标记结合二维液相色谱-串联质谱(two-dimensional liquid chromatography-tandem mass spectrometry， 2D-LC-MS/MS)对雌二醇(17β-oestradiol， E2)和血清各自以及共同作用对MCF7乳腺癌细胞内蛋白质表达的影响进行了比较，共鉴定到置信度在95%以上的蛋白质576种，其中各组相对于正常培养组的细胞共找到26种差异在1倍以上的蛋白质，其中10种上调，16种下调。

The consumer charges the polyethylene terephthalate container by pumping down on the overcap eight to 10 times, then removing it and holding down a conventional-looking aerosol button.

消费者收费的聚对苯二甲酸乙二醇酯容器抽下来的overcap 8至10倍，然后删除它，并举行了传统的外观气溶胶按钮。

In situ hybridization and immunocytochemical studies indicated that treatment with 17beta -estradiol increased the number of aromatase-immunoreactive cells and their immunoreactivities, especially in the preoptic area of the hypothalamus, where the density of the aromatase-immunoreactive cells was 2.6 folds higher than the control group. Results indicated that brain aromatase may be involved in the feminization induced by 17beta -estradiol of the grey mullet.

原位杂交和免疫细胞化学定位表明：雌二醇处理组鲻鱼脑内芳香化酶阳性细胞数量和反应强度均提高，尤其在下丘脑视前区，芳香化酶阳性细胞的分布密度为对照组的2.6倍，说明17beta-雌二醇诱导幼鲻雌性化可能与脑芳香化酶的表达有关。

Examining population growth as an index of development, he concluded that in Europe, where countries doubled their populations every five hundred years, growth was steady if undramatic.

北美的人口每隔二十或二十五年就增加一倍，因此北美的劳动力不虞匮乏；此故，「新大陆」是「比较繁荣，而以更快的速度向富裕之道迈进。

The waiter said:"It is really a good tea. If you don't believe me, you take a look yourself." Lou was handed the tea bowl doubtfully, seeing the color of soup red, dense and bright, having a drink, melon and smooth, really better one hundred times than usual one. He perked up at once bethinking of why thus?

小二说：&真的是好茶，你咋个不信，自己瞧瞧&，罗千总这才半信半疑地接过小二端来的茶碗，一看汤色红浓明亮，喝上一口，甘醇爽滑，的确赛过自己平常喝的茶百倍。
