To address more specifically the mechanisms involved in cortical bone healing, we created drill-hole defects in the cortex of mouse femur, a lesion that triggers intramembranous repair, and compared the roles of bone sialoprotein and osteopontin, two proteins of the extracellular matrix, in the repair process.

为了更具体的了解皮质骨修复过程的机制，我们在小鼠股骨上制造了一个钻孔缺损，这一损伤能引发股骨的膜内修复，并比较细胞外基质中的两种蛋白骨涎蛋白和骨桥蛋白在这一修复过程中的作用。

The leaf shape indexes of transgenic and control seedlings increase lightly when the IAA treatment concentrations are in two regions of 0~0.01mmolL^(-1) and 1.0~10.0mmolL^(-1) respectively, while LSIs decrease when IAA concentrations are between 0.01mmolL^(-1) and 1.0mmolL^(-1) this implies the depression effect on the growth in longitudinal is greater than that in transversal for both transgenic and control mesophyllous cells.

激素浓度在0~0.01mmolL^(-1)和1.0~10.0mmolL^(-1)两个区域时，转化株和非转化株的叶形指数略有增加，而在0.01~1.0mmolL^(-1)范围内，两者的叶形指数均呈下降趋势，表明IAA在此浓度范围内，叶肉细胞沿主叶脉方向的纵向生长受到的抑制强于横向生长所受到的抑制。

Further study of the interaction between NodD and naringenin by FRET technology is underway.

通过对naringenin分子上六个不同位点，不同性质，长度连接链以及母体和荧光团之间两种连接方式的11个荧光标记物的合成以及生物活性评价，我们找到了一个荧光标记物，它保留了野生型naringenin约20％的活性，并将其用于根瘤菌固氮过程的研究，发现该荧光标记物能够顺利进入根瘤菌活细胞中，为下一步通过FRET技术研究naringenin和NodD蛋白之间的相互作用打下了基础。

The above facts indicated that silicon accumulation in the rice leaf sheath inside, the leaf surface and the sclerenchymatous cell, played the physical barrier role, delayed the hypha of sheath blight expansion.5、Analysing the physiological and biochemical mechanism of the resistance to rice sheath blight improved by silicon application in several respects.(1) After being inoculated with R.solani, O2 and POD activities disordered, CAT activities obviously declined. O2 producingvelocity in 91SP\'s leaves and leaf sheaths of Si+ rice plants were lower than those of Siriceplants, MDA content in leaves and leaf sheaths of Si+ rice plants were lower thanthose of Si- rice plants significantly in three days after inoculating, SOD、POD、CATactivities in leaf sheaths of Si+ rice plants were higher than those of Si- rice plantssignificantly in one day after inoculating, SOD、POD、CAT activities in leaves ofSi-treatment were higher than those of Si- rice plants significantly in three days afterinoculating. O2 producing velocity and MDA content in Lemont\'s leaves and leafsheaths of Si+ rice plants were lower than those of Si- rice plants significantly afterinoculating, and SOD、POD、CAT activities of Si+ rice plants were higher than those ofSi- rice plants significantly.

说明硅在水稻叶鞘内侧、叶表和厚壁细胞积累，起到了物理屏障的作用，延缓了纹枯病菌的扩展。5、阐明了施硅增强水稻抗纹枯病的生理生化机制(1)接种纹枯病菌后，两个水稻品种91SP和Lemont的叶鞘和叶片超氧阴离子自由基O2性紊乱，CAT活性明显下降；抗病品种91SP叶鞘和叶片施硅处理的O2产生速率小于缺硅处理，叶鞘和叶片MDA含量在接种第3 d后显著低于缺硅处理，叶鞘SOD、POD、CAT活性在接种1 d后一直显著高于缺硅处理，叶片SOD、POD、CAT活性在接种3 d后显著高于缺硅处理；感病品种Lemont叶鞘和叶片施硅处理的O2产生速率、MDA含量始终显著小于缺硅处理，SOD、POD、CAT活性始终显著大于缺硅处理。

Using whole-cell patch clamp recording, we observed multiple distinct ATPinduced currents in isolated DRG neurons of adult rats, each with unique desensitizing kinetics.β,γ-meATP, agonist of P2X1 receptor also induced fast inactivating and slowly desensitization current in small DRG neurons. PDBu, a selective agonist for PKC, decreased the P2X receptor-mediated inward currents in a dose-dependent manner, while SNP, nitric oxide donor, potentiated the ATP-evoked current through NO-cGMP pathway.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
