In the presence of Aβ42, carnosine significantly decreased glutamate release, which was further reduced by clobenpropit and thioperamide.

我们发现Aβ42对胞外谷氨酸含量几乎没有影响，肌肽能显著降低胞外谷氨酸含量，而H_3受体拮抗剂clobenpropit和thioperamide能进一步降低由肌肽引起的胞外谷氨酸含量的降低。

The results are as follows: Both genistein and CNQX attenuated the ventilatory responses of peripheral chemoreflex, while no changes occurred following daidzein. The amplitude of integrated phrenic nerve discharge and the phrenic burst frequency were decreased by (-21.77±6.93%) and (-24.70±7.61%) respectively after administration of genistein.

结果显示，吸入低氧混合气后，动物呼吸加深加快；在NTS 处微量注射CNQX或genistein 都会不同程度削弱外周化学感受性反射引起的通气反应，而微量注射daidzein后对反射没有影响。

The ultrastructure of osteoblast and chondroblast in callus at 2 weeks after fracture has no difference between the two groups; the apoptosis chondroblast was observed in the control group.

在兔胫骨中段截骨、髓内针固定骨折模型上，sOGP每天静脉注射对新西兰兔的体重没有影响。sOGP注射组的血清ALP、BGP水平比同时段的对照组高。

In this work, we isolated 47 strains of actinomycetes from the mud sample of Jiaozhou Bay. Quorum sensing inhibitory activity was monitored by Chromobacterium violaceum CV026. As a result, the culture broth extract of actinomycetes WA-7 was found to have significant quorum sensing inhibitory activity. This strain was assigned to the genus Streptomyces based on its 16S rDNA sequence.

我们从胶州湾海泥中分离得到放线菌47株，其发酵提取物经紫色杆菌CV026模型筛选后，发现放线菌WA-7提取物具有群体感应抑制活性，且在有效浓度时对细菌的生长没有影响。16S rDNA分析表明WA-7应属于Streptomyces属。

It has been found that there exists a relationship between the coking rate and regeneration rate of the catalysts.

在再生过程中，催化剂本身对焦炭的燃烧速度基本没有影响，可以看作为惰性物。

The above results can summarize the function of STK1: insignificant effect on mycelium development and growth but related to the pigment accumulation in hypha; key factor regulating the conidial development; related to the HT-toxin activity and pathogenicity.

结论推测，STK1基因对玉米大斑病菌菌丝的生长发育没有影响，但可能与菌丝中色素等物质的积累有关，并调控病菌分生孢子的发育、HT-毒素的活性和致病性。

It was demonstrated that when 0.10molL〓HCl was used as internal electrolyte, higher sensitivity and lower detection limit were obtained, and other copresent gases, such as CO, NO, NH〓 and CO〓, hardly had effect on responses of SO〓.

结果表明，以0.10molL〓HCl作为内充电解液，将此气体传感器用于测定二氧化硫，得到的检测限较低，且CO，NO，NH〓和CO〓等共存气体对二氧化硫的测定几乎没有影响。

A dose-dependent inhibition of cGMP-PDE activity was observed when cUMP 10~(-6-10~(12) M was added to the culture medium, which may explain the increase of the level of intracellular cGMP, while the activity of cAMP...

浓度为10~(-6)-10~(-12)McUMP对胞内cAMP-PDE活性几乎没有影响，而抑制cGMP-PDE的活性，抑制作用随cUMP浓度降低而减小，这可能是胞内cGMP水平增高的原因。cUMP可能与细胞的cAMP PK结合，释放催化亚单位，细胞生长的抑制可由此发生。

The results show that the effect of addition or no-addition of degasser on grain refinement of Al-5.0%Si alloy ingot is...

结果表明，除气剂的添加与否对Al-5%Si合金铸锭组织的细化没有影响，铸锭由粗大的柱状晶组织构成；采用合适的超声波处理时间，Al-5%Si合金铸锭的等轴晶获得率大幅度提高，可使整个铸锭组织变为细化的等轴晶组织；超声波振动时间过长将导致铸锭内气孔的增加；根据克劳修斯-克拉柏龙方程，某一强度的超声波引起的压力冲击波作用，导致液相转变为固相，引起了超声波的细晶作用。

The SDS-PAGE electrophoresis indicated that all engineered strains containing different expression plasmid could apparently express a 45 kD band specific for daunorubicin C-14 hydroxylase. The expression level of doxA gene was much higher when the doxA gene was under the control of promoter PermE. However, it was found that fd terminator had few effect on the expression of doxA gene.

SDS-PAGE蛋白电泳实验证明，上述五个菌株都能够表达大小约45 kD的柔红霉素C-14羟化酶蛋白，并发现以在PermE启动子控制下的doxA基因表达量相对较高，而终止子对＠中英文摘要 dd基因表达似乎没有影响。

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。
