The experiments also showed that Eclean restrained the growth of some blue algae such as anabaena flos-aquae and Oscillatoria tennis and some green algae such as chlorella. vulgaris. This shows that the seaweed extract Eclean is very important and very useful in controlling the blue algae water bloom.

EClean对不同藻类的抑制性试验表明,EClean对蓝藻门的水华鱼腥藻(Anabaenaflos-aquae)、小颤藻和绿藻门的小球藻有明显的抑制作用,对绿藻门的斜生栅藻和裸藻门的血红裸藻的生长有一定的促进作用,显示出EClean对蓝藻性水华的治理具有重要意义。

Hewever the caspase-3 expression was still very high in cortex. Conclusion: In KA model the hippocampus amygdala plays a key role in epilepsy. Therefore it provides a mimic optimal conditions for human temporal lobe epilepsy study. Its an effective method of studying the development, change and pathopoiesis of epilepsy. There is a close relationship between NPY and epilepsy. The regulation of NPY via VPA may be one of the antiepilepsy mechanism of mechanism of VPA. Moreover NGF can enhance the caspase-3 expression. Excito-amino acid can aggravate the apoptosis, which may be one of the reason for intractability of epilepsy.

KA模型因其海马杏仁核在癫痈中起核心作用,故具有模拟人类颗叶癫痈的理想条件,是研究癫痈发展变化、致痈机理的有效工具,NPY与癫病有着密切的联系,VPA调节NPY有可能是其抗癫痈机理之一,而NGF对caspase一3表达有促进作用,兴奋性氨基酸可造成细胞凋亡的增加,而凋亡细胞的增多有可能是癫痈久治不愈的原因之一。

Also the performance of this modified electrode was compared with sodium molybdate modified platinum electrode. The cyclic voltammetry tests show that phosphomolybdic acid modified platinum electrode can increase the catalytic activity for methanol oxidation and it is almost the same as the mono-molybdate (Na2MoO4) modified Pt electrode does. This promote effect mainly comes from the transformation of different valency of molybdenum.

通过循环伏安和计时电流法研究了该修饰电极对甲醇氧化的电催化活性和抗中间产物的毒化作用,并比较了该修饰电极与其单酸盐(Na2MoO4)修饰铂电极的性能,测试结果表明:磷钼酸修饰铂电极能够提高对甲醇氧化反应的催化活性,基本上同其单酸盐Na2MoO4修饰铂电极的催化活性相当,并且这种促进作用主要是由Mo原子价态变化引起的。

BACKGROUND: Our early study has found that the effect of pulsed electromagnetic fields can promote the proliferation of the precartilaginous stem cells.

摘要背景:前期研究证实脉冲电磁场对前软骨干细胞增殖具有促进作用,但其作用机制不明确。

Basing on the result of preformulation, the transdermal transit cumulate dose chosen as index, the effect of transdermal permeability of OXA by HPMC and sodium hyaluronate was investigated.

实验结果显示,棕榈酸异丙酯对四种药物的体外经皮渗透性均具有促进作用,尤其是对亲脂性药物促渗作用尤为显著。

The result suggests that IGF-IR and EGFR might be involved in mediating the effects of energy intake on the development of reproductive system in prepubertal gilts.

结果表明:日粮能量水平显著影响初情期前母猪卵巢上两种生长因子受体的表达,高能量对表达有促进作用,有利于两种生长因子作用的发挥,从而利于生殖系统的生长发育;因此,IGF-1R和EGFR可能参与介导能量摄入对初情期前母猪生殖系统发育的影响。

Poplar belongs to Salicaceae, Populus. There are more than one hundard kinds in the world, while more than fivty-seven in China. So, poplar is more important than other trees for not only protecting ecology but also advancing country economy development.

杨树属杨柳科,杨属,全世界杨树有100多种,而我国就有57种之多,因此无论对于生态还是对国民经济的促进作用,杨树都起着其它树种所无法比拟的作用。

Secondly, we used M-07e cells as targets to further study if the mechanism of heparin in synergy with TPO was involved in the way of signal transduction trigged by TPO, because heparin could act synergically with TPO in stimulating M-07e cells growth.

因为肝素也能协同TPO对M-07e的增殖促进作用,我们以M-07e为靶细胞,进一步研究肝素协同TPO的作用是否涉及TPO触发的信号传导途径。

Thus the calcium thenardite becomes penetrable porous medium, holding the pervasion and mechanical characteristics that are called solution pervasion and mechanical characteristics, respectively.

由于矿物组分溶解特性的差异,在一定渗透压力作用下,钙芒硝盐岩体内会产生溶解渗透交互促进作用,从而由低渗透介质变为高渗透的多孔介质,其渗透及力学特性受其矿物组分硫酸钠溶解程度的影响极大,这种特性称之为溶解渗透力学特性。
