碱的

The effect of codon content in 3rd codon position shows much grater than the other positions.

碱基含量对该碱基在第三密码位的分布的影响要远大于其他的两个密码位。

Control of orange scale in the field with a formulated Haolun gum resin compound WU Jing-cai, WANG Zi-qi (Training Center, Fujian Academy of Agricultural Sciences, Fuzhou 350003, Fujian, China) Abstract: Field experiments in three provinces showed conclusively that a 45% formulation of Haolun gum resin compound is a good pesticide for control of orange scale.

浩伦松碱合剂防治柑桔蚧壳虫的田间应用吴敬才，王子齐(福建省农业科学院培训中心，福建福州350003)摘要：通过在3个省份的田间试验充分表明，浩伦松碱合剂是防治柑桔蚧壳虫的良好药剂。

In this thesis, a series of derivatives of -Huperzine A and benzylpiperidine were designed and synthesized, including nonsteroidal anti-inflammatory drug derivatives, heterocycle derivatives, aromatic derivatives and its sckiff derivatives, etc.

全部目标化合物进行了胆碱酯酶的活性测试，石杉碱甲类衍生物的乙酰胆碱酯酶活性比母体差，说明该类取代基在胺基上取代可能会使石杉碱甲衍生物的活性降低。

On the contrary, there were no significant alternation in the levels of PKCδ and PKCε after HupA treatment, indicating no contribution of these two subtypes.

同时还观察到，石杉碱甲对PKC另外两个亚型PKC与PKC的蛋白水平没有明显的影响，提示石杉碱甲增加sAPPα分泌的作用与PKC、PKC没有关联。

The pharmacological profile of HupA is similar to that of tacrine, including the inhibition of AChE, the antagonism to the NMDA receptor, and the neuroprotection in vitro.

目前，石杉碱甲对离子通道的作用还知之甚少，因此本论文将着重研究石杉碱甲对脑内电压门控通道的作用，并探讨其可能的作用机制。

Secretion of sAPPα and expression of PKCα were found to increase after cells were incubated with HupA, suggesting a possible correlation between these two changes.

Western blotting结果显示sAPPα和PKCα蛋白水平均随着与石杉碱甲孵育的时间增加而增高。sAPPα的显著上升出现于PKCα上升之前，提示石杉碱甲对sAPPα分泌的调节可能与提高PKCα表达水平有关。

Increases of APP transcript and expression by HupA also contribute to the up-regulation of sAPPα secretion. Meanwhile, Aβ secretion was observed to decrease 2 h after HupA treatment, and after 24 h incubation, HupA can significantly inhibit the secretion of Aβ.

Real-time PCR和Western blotting结果提示石杉碱甲能增加APP的转录和表达，该作用也将有助于对sAPPα分泌的上调；同时Aβ的生成并未相应增加，ELISA检测结果显示石杉碱甲孵育2 h后即能对Aβ分泌产生抑制作用，孵育24 h后能显著降低Aβ水平。

Treated with high concentration of piperine （0.56 mmol/L） for 24 hours and 48 hours respectively, following a period of growth retardation, the cells of 24-hour-group could recover slowly while the 48-hour-group showed inconvertibility.

由此认为：胡椒碱对C6/36细胞株有毒性作用，但药物诱导的细胞凋亡在细胞毒性作用机制中不占主导地位；胡椒碱对C6/36细胞的作用有时间依赖性，延长作用时间，药物对细胞的毒性作用增强。

The results suggest that CHBr3 is likely to intercalate into ctDNA and such intercalations mainly depend on the relative binding affinity of a metal ion to the bases and to the phosphate groups in DNA.

据此推断，CHBr3可能主要是通过嵌插作用与ctDNA碱基结合，金属离子对CHBr3与ctDNA结合的影响主要取决于金属离子与DNA的碱基和磷酸基团间结合的相对亲和比。

The amount of similarity of F3H genes in the species of batatas and purpurea within the genus of Ipomoea is the highest with 94 points given.

FLS基因在2个物种中有21处5和5个以上连续的恒定的碱基保守区序列。F3′5′H基因在2个物种中有23处5个和5个以上连续恒定的碱基保守区。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
