Was applied to the AD reaction of eight olefins in PEG/NMO system according to the protocol of ligand 8. The yields and ees of the diols were 70～90% and 77～96%(except for trans-5-decene and ally naphthyl ether) respectively.

在与8相同的催化反应条件下，手性配体9催化八种烯烃的AD反应得到的化学产率和ee值分别为70～90％和77-96％（反式-5-癸烯和萘基烯丙基醚除外）。

The results of AD reactions are as follows:(1) When the AD reaction of eight olefins was performed at 0.5mo1% OsO〓 and 2mol% ligand 8 in PEG/NMO system, the diols were obtained in 78～90% yields and 78～96% ees (except for trans-5-decene and ally naphthyl ether).

催化结果如下：(1)在PEG/NMO体系中，将配体8用于八种烯烃的AD反应，配体、OsO〓和底物的摩尔比为0.02/0.005/1时，化学产率为78～90％，除反式-5-癸烯和萘基烯丙基醚较低外，其它六种烯烃的相应二醇产物的ee值为78～96％。

Octylene was synthesized via tetramerization of ethylene at the presence of a catalyst system consisted of chromium acaet as primary catalyst, methylaluminoxane as cocatalyst, bis amine as ligand under high pressure. The effects of different PNP ligands on catalyst activity and selectivity to 1-octene were investigated.

在乙酰丙酮铬、甲基铝氧烷、配体三元催化体系中，以乙烯为原料在高压下齐聚生成1-辛烯，主要考察N原子上取代基不同的PNP配体对催化剂活性及1-辛烯选择性的影响。

We found that over-expression of the Notch ligand, Jagged-1, activated the Notch signaling pathway in DPSCs. Jagged-1 inhibited the odontoblastic differentiation of DPSCs in vitro.

Notch配体Jagged-1的过表达能激活DPSCs的Notch信号通路，在体外抑制成牙本质细胞谱系分化。

The osmium-catalyzed asymmetric dihydroxylation of olefins provides one of the most effective methods for the preparation of vicinal diols. Almost all kinds of olefinic substrates can be transformed to the corresponding diols by means of AD reaction. The chiral osmium catalyst is generated in situ by the chiral ligand complexing with OsO〓 in the reaction.

手性锇催化剂催化的烯烃不对称二羟基化反应是合成手性邻二醇最有效的途径之一，可以将几乎所有类型的烯烃转变成相应的手性邻二醇，因此广泛地应用于药物、天然产物以及精细化工产品的合成。

Part 1 :abstract : Long-term neuropsychological abnormality has been documen ted in child born to morphine addicted mothers, but the mechanism of this phen omenon until now is not clear. Our previous ligand binding study has shown tha t combined prenatal and postnatal chronic treatment of morphine could alter th e ontogenic expression of the NMDA receptor.
