Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastocysts followed by fusion of cytoplasm and nucleus and cleavage in vitro. During the fusion of cytoplasm, the DNA methylation levels of the fused embryos are as high as these of two-cell diploid embryos in vivo Then the embryos are rapidly demethylated when the nucleus begin to fuse, resulting in the lowest DNA methylation levels when the nucleus are fused completely. After that, the DNA methylation levels of the fused embryos are gradually increased until the morula stage. However, whereas an asymmetric distribution of DNA methylation is established in vivo-derived blastocysts with a higher methylation level in the inner cell mass than that in the trophectoderm, we can not detect the asymmetric distribution in most in vitro-derived tetraploid blastocysts.

结果表明：利用电融合方法制备的小鼠四倍体胚胎在体外培养体系中经历细胞质融合、细胞核融合及细胞继续分裂发育直到囊胚期的过程，在细胞质融合的时候胚胎卵裂球同体内体外培养二倍体胚胎一样，呈现高度甲基化状态；在细胞核开始融合的时候，甲基化水平急速下降，在细胞核完全融合的时候甲基化水平达到最低点；随着胚胎继续分裂，胚胎甲基化水平逐渐增加，在桑葚胚期甲基化水平最高；但是囊胚期四倍体胚胎内细胞团同滋养层细胞甲基化荧光信号没有差别，这与体内体外培养二倍体囊胚内细胞团细胞甲基化荧光强度高于滋养层细胞甲基化荧光强度不同。

Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastcysts fellowed by fusion of cytoplasm and nucleus and cleavage in vitro.After fusion of cytoplasm, the DNA methylation levels of the fused embryos was very high as well as two-cell diploid embryos in vivo.Then the embryos was rapiddly demethylated when the nucleus begin to fuse, resulting the lowest DNA methylation levels when the nucleus fused completely.After that, the DNA methylation levels of fused embryos were gradually increased until the blastocysts stage.However, whereas an asymmetric distribution of DNA methylation was established in an vivo-derived blastocysts with a higher methylation level in the inner cell mass than in the trophectoderm, in most vitro-derived tetraploid blastocysts, we can not detect the asymmetric distribution.

Then place your heels on the pedals and adjust the saddle height so that your legs are fully extended on the downstroke, yet your hips don't rock as you pedal.

然后，你用你的脚后跟踩在脚踏上面，调整座垫高度，使你的腿能在用脚后跟登踏到最低点是完全伸直，注意，此时，你的屁股不能在座垫上左右摩擦。

Ignorant and inexperienced, it is not strange that in the first years of our new life we began at the top instead of at the bottom; that a seat in Congress or the State Legislature was more sought than real estate or industrial skill; that the political convention or stump speaking had more attractions than starting a dairy farm or truck garden.

由于我们无知，又缺乏经验，所以在我们新生活的最初，几年里，我们没有从最低点而是最高点开始努力；我们奋力争取在国会和州立法机关的席位，却忽视了培养房地産经营的能力和工业技能；我们被政治会议或树墩演讲所吸引，而觉得经营牛奶场或蔬菜场乏味，这种现象并不奇怪。

If you have pyramided until you h ave 25,000 bushels, then you should have an order in to sell 30,000 bushels on stop, which would put you short 5,000 bushels to start a new deal.

如果你长线操作，总是将止损设定在不要超过趋势线底部1美分或者每天的是最低点上面1美分处，，如果短线，则不要超过趋势线顶部或者每天最高点1美分处。

Tian Qing: This will definitely not like before, be it macro-economic or stock market will not be a V-bottom, I think the bottom will become L-type, at the bottom of the Is likely to continue a long period of time, which is the medium and long term under a conclusion.

田沏嗯：这绝不像以前，无论是宏观经济还是股市不会是V形底，我认为底部将成为L型在会降至最低点，持续时间长的时期，这是中，下结论长期。

Steel plate with the current valuation level in 2005 on the Topix index and the lowest point in 2006 when the stock prices of steel at the time of the most depressed valuation levels compared to the valuation of listed companies in the level of iron and steel has been lower than the lowest level in history.

Soybeans and soyoil, however, did close near their lows for the day with soybeans settling single digits higher.

但是，大豆和豆油期价在收盘时却接近全天最低点，其中大豆期价仅以一位数的升幅收盘。

Results: The results indicated that the patterns were completely different between two performances of hammer throw. The curvature radius of better one was more periodic than the other one, and was larger at the highest points and the lowest points of the orbit during hammer throw.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
