修饰

The relationship between molecular modification of erythromycin and NMR chemical shifts was summarized. It's noticeable that downfield of shifts of H-3 (△δ 0.2) after silylation and upfield of shifts (△δ-0.4) after methylation. No changes were observed after methylation.

分析总结了红霉素分子修饰与核磁共振化学位移变化之间的关系，并且发现大环上H-3硅烷化后由高场移至低场（△δ为0.2），甲基化后又由低场移至高场（△δ为-0.4），变化均较大；而且一旦甲基化后H-3化学位移在高场几乎不再变化。

But, as you draw closer, more crucial differences than the merely cosmetic emerge.

但当你越来越接近的时候，更多至关紧要的差别比仅限于外表上的修饰更……。

You can scan locations for images and it includes drawing tools and modifiers.

你能够因为形象浏览所在和它包括移动工具和修饰工具。

But by dressing black tie down or putting a new spin on it, suddenly the men can look more interesting too.

但如果休闲地穿上无尾礼服或者在上面加上新的修饰，顿时男士们也会看上去更有趣。

This was an innate eccentricity and love of embroidery, I do not know why

这是我们固有的一种怪癖，喜欢修饰，究竟如何，我就不知道了。

In this report, the 59Tc labelling of Annexin V fragment modified with HYNIC (HYNIC-Anx13) using Tricine, EDDA or EDDA/Tricine as coligands was described. The effect of various factors on 99Tc labelling was investigated. Biodistribution studies in normal mice and gamma imaging of apoptosis in rats induced by cyclophosphamide were performed.

为探讨99Tc标记的HYNIC-Anx13用于细胞凋亡显像的可能性，分别以N-［三甲基］甘氨酸，乙二胺－N，N'-二乙酸和EDDA/Tricine为协同配体，对经6-肼基烟酰基修饰的膜联蛋白V片段(HYNIC-Anx13)的99Tc标记条件和主要影响因素进行了研究，并完成了HYNIC-Anx13的99Tc标记物在正常小鼠体内的生物分布和大鼠细胞凋亡模型的显像实验。
