因此，要实现东鞍山含碳酸盐铁矿石中铁矿物和石英的有效分离，关键是如何在反浮选之前预先将菱铁矿分离出去，或找到能有效活化或抑制菱铁矿的浮选药剂。

Implant into silicide method is one possible method to activate dopant at low temperature.

离子布植进入矽合金法是一种能在低温下活化载子的方法。

And also, we unexpectedly discovered a ring-opening reaction of aziridines or epoxides with iodine promoted by thiophenol.

我们认为，在反应中，DMSO自身作为一种Lewis Base，能有效活化亲核试剂，从而促进反应的顺利进行。

If you don't have this advantage but do have some electronics skills, you can put any one of a number of other miniature snap action ("tactile feel") switches in there if you can adapt them mechanically to the small circuit board and the activation spring from the foot treadle.

如果你没有这方面的优势，但也有一些电子技巧你可以在任何一个其他一些小型抢夺行动开关有你能适应机械式的小型电路板和活化春天从脚下的踏板。

Taken together, these results suggest that ErbB-2 signaling promotes matriptase zymogen activation through PI3K/Akt pathway in human prostate cancer cells, which contributes to an invasive ability.

综合上述结果，我们可以得知，在人类摄护腺癌细胞中，ErbB-2的讯息能透过PI3K/Akt路径而促进间质蛋白酶的活化，并因此而增加细胞的侵袭能力。

Previous studies suggest that hepsin is involved in cell growth and migration. It is also shown to interact with coagulation Factor VII, and convert zymogen factor VII to factor VIIa.

近几年研究发现，hepsin在前列腺癌细胞株有过量表现，与抑制癌细胞的生长及转移相关；并能在缺乏组织因子状态下活化血液第七凝血因子，启动外源性凝血反应。

These results suggested that the lung Fib were activated and produced excess HA, resulting in the excessive accumulation of HA within the lung at the stage of alveolitis during the process of pulmonary fibrosis. However, increased HA synthesis of lung Fib and increased HA levels in BALF merely reflect the intensity of alveolitis and the disease activity rather than the degree of pulmonary fibrosis.

以上结果提示：肺Fib在肺纤维化的早期肺泡炎阶段就处于活化状态，产生HA增多，导致肺内HA的过多聚积，肺Fib产生HA增多和BALF中HA水平的增高可反映肺泡炎的强度和疾病的活动性，但并不能反映肺胶原代谢或纤维化的程度。

This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

A series of antimony mercaptide compounds which formula are Sb 〓 and Sb S (CH〓〓COOR 〓(R represents an alkyl or aryl, aralkyl, n=0～2) have been synthesized. A new synthetic method has been invented to solve the defect of abroad patent method which has complex technological conditions and singleness intermediate compounds. A new catalyst QL-1 and preactivated antimony trioxide and other means have been used to avoid neutralizing, washing, separating and other procedures of intermediate and simplifing process flow at the same time. According to this new technique, a series of antimony mercaptides and their intermediate products have been synthesized with high yield.

合成了结构为SbS(CH〓〓COOR〓及Sb〓（R为烃基或芳烷基，n=0～2）的一系列硫醇锑化合物，针对国外专利报道的合成工艺存在着工艺条件苛刻，同时需多步完成，操作复杂，而且中间体品种单一的缺陷，发明了一种一步法合成硫醇锑化合物的新工艺，采用QL-1催化剂，且将三氧化二锑预先活化，变固—液相反应为液—液相反应，同时可免除中间体的中和、洗涤、分离等工序，工艺流程简化，产品收率高，且能制得系列硫醇锑产品。

Helps replenish nutrients, activate cellular renewal, prevent skin aging, and promote blood circulation, while eliminating areolar tissue on cuticular layer and roughness of horny layer.
