不再发生的

One possibility, she says, is that the altered cells become so engorged with unburnt fat, they become "diabetic", no longer accepting signals from the hormone insulin, which normally triggers the absorption of glucose from the bloodstream.

她说，她的研究小组的研究结果为解释这种现象是如何发生的提供了新的线索，并可能有助于解释成年人是如何患上II型糖尿病的。其中一种可能，是变异细胞充满了太多未燃尽的脂肪，他们也患上了"糖尿病"，不再接受胰岛素正常发出的从血液中吸收葡萄糖的信号。

Through such a study, it is also shown that when the time delay is long enough such that the stability switches of the equilibrium of system halt, the bifurcation branches originated from the critical time delays cannot be surely stable or unstable in the whole solution space, that is, their stability depends on cases.

利用打靶法的数值结果说明了当系统平衡点不再发生稳定性切换时，源自这些临界时滞处的解支的稳定性在整个解空间的稳定性具有不可判定性，这也说明由多尺度法所得高阶近似判定的解支的稳定性事实上只表示解支在局部中心流形上的稳定性，而非在整个解空间中的稳定性。

This requires a transformation of your being, a conscious attitudinal shift from your side.

这需要你将现在的自己转变到一个更有意识的明晰状态（而不再是懵懵懂懂迷迷糊糊被动的经历着在你身上发生的一切）。

LX2 cells were transfected at the adenovirus tite pfu100, and were harvested at different times (24,48,72h), then western blotting was executed to detected the expression of ectogenous ampk.

对凋亡信号通路的进一步研究发现，Bcl-2在LX2中是低表达的，而Bax在AMPK过表达之后，表达增加，而用RNAi方法敲低Bax之后，细胞再用携带AMPK基因的腺病毒感染，LX2细胞不再发生凋亡，说明Bax参与了AMPK诱导LX2凋亡的信号通路。

A one-step method for the synthesis of aromatic indolizine derivatives byintramolecular 1,5-dipolar cyclization reaction of 2-(2-arylethenyl)pyridinium N-ylidesin the presence of an oxidant has been studied for the first time. In the presence ofelectron-deficient olefins, however, 2-(2-phenylethenyl)pyridinium N-ylides underwent1,3-dipolar cycloadditions and then aromatized in situ by TPCD to produce indolizinederivatives, indicating 1,3-dipolar cycloaddition proceed more readily than 1 ,5-dipolarcyclization in these conditions. Pyridinium disubstituted N-ylides, readily obtainedfrom corresponding pridinium and β-chlorovinyl ketone, underwent thermalintramolecular 1,5-dipolar cyclization to give indolizine derivatives easily.Indolizinecarbaldehyde derivatives were synthesized starting from 2-pyridinecarbaldehyde in four-steps involving 1,3-dipolar cycloaddition reaction.

本文首次研究了2-(2-芳基乙烯基)吡啶N-叶立德在氧化剂存在下的分子内1，5-偶极环化反应，采用一锅法合成了中氮茚衍生物；研究了这些N-叶立德的1，5-偶极环化和1，3-偶极环加成反应的选择性，发现当有缺电子烯烃存在时，优先进行1，3-偶极环加成反应，而不再发生分子内1，5-偶极环化反应；由β-氯乙烯酮方便地得到了烯丙基N-叶立德，他们在加热时进行分子内1，5-偶极环化反应而得到中氮茚衍生物；由2-吡啶甲醛为起始原料，通过1，3-偶极环加成反应等四步反应，得到了重要的中氮茚甲醛衍生物，这些反应都具有条件温和和操作简便的特点，是合成中氮茚衍生物的新方法。

The results showed that the W content in the electrodeposits rose with the increasing of cathodic current density in the solution containing ammounium citrate as complexing agent,whereas the current efficiency remained approximately constant. When the current denisity was higher than 15 A/dm2, the W content in the alloy was not obviously changed, but the current efficiency remarkably decreased.

结果表明，在以柠檬酸铵为络合剂的镀液中，沉积层的W含量随电流密度的增大而增加但电流效率变化不大，当电流密度超过15A/dm2后，镀层的W含量不再发生明显的变化而电流效率却明显降低。

Time passed quickly, today is my first anniversary of study in Canada, it is the beginning of new semester as well. This afternoon, I was in the library toenjoy the memories of the past in last year......Celebrated the lunar new year and went to see the parade in Chinatown with myself; Everthing was stolen except clothes and pants, however, themain "confort" of my landlord is focused on "Did you lose your bank card?"; Overflying Canada from Vancouver to the Toronto by myself to look forthe new life; Met new friends and classmates here,no longer struggle lonely!

一年的时间转瞬即逝，我的一周年纪念日也是新的一学期的开始，下午，一个人在图书馆回味着这一年发生的事……一个人过春节，去唐人街看游行；东西全被盗了，穷的只剩下衣裤，房东的第一句&慰问&居然是&你的银行卡丢了吗&；只身一人跨越加拿大，从西部温哥华飞到东部多伦多，寻找新的生活；结识了新的朋友和同学，不再是一个人在奋斗！

Descriptions of the 1948 war tended to suggest that Palestinians either left their homes voluntarily, selling them to Jews, or were encouraged to leave by other Arabs—rather than, as sometimes happened, being forced out violently. Maps of pre-1948 Palestine sometimes underplayed the extent of Arab habitation, while maps of modern Israel never included the "Green Line", the pre-1967 border; this makes the occupied territories of Gaza and the West Bank look as if they were an integral part of Israel.

对1948年战争的描述则往往暗示，巴勒斯坦人要么是自愿离开家园并将之卖给犹太人，要么是被其他阿拉伯人鼓动离开——而并非象时不时发生的那样是被暴力地强行驱出。1948年之前的巴勒斯坦地区的地图有时候对阿拉伯人居住范围描述得并不充分，当现代以色列的地图不再包括&绿线&——1967年之前的边界——部分在内的时候，就使得被占的加沙和西岸地区的领土看起来是以色列不可分割的一部分。

In France,he completed the most important three-act play "The home of the village".The play was obviously different from his preceding works, the plot of the play was from the simple to complex, the characters were from the single to multiple, and the drama background happened in North Chinese village in the countryside other than in the city,so the works was recognized as the most important plays written in France .

在他留法期间完成的最重要的一个三幕剧《村长之家》，这个剧本与李健吾以前的剧作明显不同，故事情节由简单变为复杂，人物性格由单一变为多重，剧情发生的背景也不再是城市，而是&华北乡间某村镇上&，实际上就是以他的故乡安邑西曲马村为蓝本。

Global warming, destroying of ozonosphere, desertization, acid rain and other environmental problems are not any problems of one country because these problems have threatened fundament for survival of all lives on the earth.

在我们身边发生的地球温暖化及臭氧层破坏、沙漠化、酸雨等地球环境问题不再是某一个国家的问题，如今已经成为威胁到地球上所有生物赖以生存的根本的问题。
