Notch1 is expressed by stem cells resided in the cervical loop epithelium, and Notch signaling pathway play a central role in fate decision of those stem cells. Notch receptors and their ligands are involved in both patterning and cell fate determination during odontogenesis. Moreover, many cell factors, which are closely related with odontogenesis, could regulate expression of Notch receptors or their ligands.

既往研究显示：早在牙齿发育期，Notch1就表达于颈环星网状层的干细胞中，是其保持干细胞性质的重要机制；Notch-Delta信号还与成釉细胞、成牙本质细胞分化有关，被认为是牙齿发育细胞分化多样性的原因之一；另外，目前已明确与牙胚细胞分化有关的生长因子如TGFβ、FGF、BMPs等均可诱导Notch受、配体的表达。

This method can exempt pain and trauma from operation, avoid postoperative complications, utmost maintain oviducal structure and function to reserve procreative function, especially to the femme of desiring procreation.

保守治疗可免除手术痛苦及创伤，避免了术后并发症，同时最大限度的保持了输卵管的结构和功能，达到保留生育功能的目的，尤其适用于有生育要求的妇女。

The 400-meters dash belongs to ultimate periodic games and is regarded as a short-distance run which can be divided into 3 periods—the period of acceleration, period of remaining maximum speed and the period of attenuation. The 400-meters dash follows the statistic rules which can be reflected from the following stage: starting the race, accelerating, reaching the maximum speed and gradually attenuating. In fact, it reflects the process that energy is provided. It is a changing process of energy providing—from phosphagen system,glycolysis system to aerobic oxidization system.

400m跑属于极限强度的周期性运动，被视为一项以速度为主的体能类短跑项目，其全程速度的变化一般可分为三个阶段，即加速阶段、最高速度保持阶段和速度衰减阶段。400m跑从起跑加速到获得最大速度后又逐渐降低的统计学规律，实质上反应了能量供应方式从磷酸原系统、糖酵解系统到有氧氧化系统的转变过程。

Stability is the most important basic feature of the ecological system. Through the study of this stability, it can guide people to make full use of and remold the nature. The research has great theoretical and practical significance for the sustainable development of the ecological environment.

稳定性能够描述生态系统的重要的基本特征，通过对种群稳定性的研究可以更好地指导人们利用自然、改造自然，对保持生态系统的可持续发展有着广泛的理论和现实意义。

Among Mr Srinivasan's reasons for optimism are the much greater levels of ownership in other South Asian countries where income levels are higher, such as Malaysia, Thailand and Indonesia (where TVS has recently opened a factory that can build 300,000 units a year).

在其他收入水平相对较高的南亚城市，例如马来西亚、泰国和印度尼西亚（TVS新建摩托年产量可达30万辆工厂的所在地），摩托的拥有量也在较高水平；而这也正是Srinivasan先生保持乐观的原因。
