The powerful emotions that bowl over new lovers are triggered by a molecule known as nerve growth factor, according to Pavia University researchers.

据路透社11月30日报道，意大利帕维亚大学的研究人员表示，让刚坠入爱河的情侣疯狂相恋的是人体血液内的那些&爱情分子&——神经生长因子。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst. The effect of the internal quaternary ammonium and/or pyridiniumsalt on the epoxidation of substituted chromenes is similar to that of the externalpyridinium salts and ammonium halides.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

In order to improve the resistance to bacterial blight of high quality rice male sterile line Jinshan A , in this study, the Jinshan B and IRBB21 that carried gene Xa21 were used as parents to make backcrosses, and both foreground selection and background selection were carried out by means of marker assisted selection in the backcrosses.

本研究以IRBB21为Xa21基因的供体亲本，以金山B为轮回亲本进行回交，并应用分子标记辅助选择技术对回交各世代同时进行前景选择和背景选择，得到如下结果：(1)利用Xa21基因内的STS标记MXA21对各回交世代进行前景选择，得到了44个带有Xa21基因的BC_1单株和40个带有Xa21基因的BC_2单株。

As far as the Fe catalytic system, the higher the Al/Fe molar ratios, the stronger Lewis acidities and the higher reactivates of carbon-aluminum bond in the cocatalysts resulted in the higher polymerization activities.

以铁配合物为主催化剂时，各种助催化剂催化乙烯聚合活性随Al／Fe比的增加而升高；助催化剂的Lewis酸性越强，其分子内碳—铝键的反应活性越高，聚合体系的聚合活性则越高。

A conjugate addition of alkadienyl carbonyl compound with vinyl palladium intermediates which can be formed from oxypalladation of alkynes or allenes was studied, and 1, 6-addition products were obtained.

发现不饱和烃的分子内氧钯化得到的烯基钯中间体能够与不饱和共轭双烯的醛酮反应，选择性的得到1，6-加成产物。

Although we have not a tool to directly modulate the cellular Cdc42/Rac activity at present, nevertheless, from the abolish of BDNF-triggered attraction by either DN-Cdc42 and CA-Cdc42, we propose that an intracellular Cdc42 activity gradient may also be sufficient to determine the turning direction, say, filopodia extend preferentially at the higher Cdc42 activity side, and the growth cone turn towards this direction in the hence.

虽然我们目前还没有一个直接操纵细胞内 Cdc42或其下游分子活性的方法，但从 DN-Cdc42和 CA-Cdc42均阻断到 BDNF 和 ryanodine 的吸引作用来看，我们推测， Cdc42的活性梯度很可能也能够决定生长锥转动方向，即丝状伪足在 Cdc42活性高的一侧优先延伸，生长锥朝向该侧转动。

In order to explore further mechanism, the present study was designed to investigate the relationship between the protective effects of F2 on myocardial I/R injury and expression of Egr-1, which could be a master switch in I/R injury.?

为进一步完善F2保护心肌缺血再灌注损伤作用的分子机制，以缺血再灌注损伤过程中起重要作用的Egr-1为研究对象，明确F2的作用机制是否与通过影响Egr-1在心肌组织内的表达有关？

As to the uses of these molecule-size ROBOTS, there is little that cannot be imagined: scraping fatty deposits from the insides of hardened arteries, brain surgery on individual neurons, food-making, ore-mining ...

至于如何应用这些分子大小的机器人，怎么想都可以：刮去硬化动脉内的脂肪沉积物，对单独神经细胞的脑手术，烹调，采矿……这样的建议无穷无尽。

For the fourth part, we first designed a hydrogen bonding-mediated rigidified polymer. The X-ray crystal analysis of its fragment molecules showed the existence of consecutive intramolecular hydrogen bonds, which forced the backbone to adopt a rigidified planar conformation.

在第四部分工作中，首先我们设计了一种分子内氢键控制构象的聚合物，通过对其氢键骨架的单晶培养和结构解析证实在它们的结构中存在三中心氢键使得它们采取平面刚性的构象。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
