In addition, a metabolic inhibitor, actinomycin D has no effect on enzymatic activities of caspase-1/ICE-like and caspase-3/CPP-32/like proteases during Fas-mediated CD4〓T cell apoptosis. These results indicate that the appearance of caspase-1/ICE-like and caspase-3/CPP32-1ike proteases activities is a post-translational activation of these proteases. It is likely these caspases constituently express in a inactive form in the cytosol of CD4〓T lymphocytes. Once the rest SEB-responsive CD4〓T cells are restimulted, those inactive caspases such as caspase-1/ICE-like and caspase-3/CPP32-1ike proteases are sequentially cleaved to become active forms, and the apoptotic signal is transducted to downstream signaling molecules, Finally leads to CD4〓T cells apoptosis.

另外，通过代谢抑制剂放线菌素D对超抗原SEB诱导静息SEB应答〓细胞凋亡过程中Caspase成员酶活性变化的研究表明Caspase-1／ICE样，Caspase-3／CPP32样胱氨蛋白酶并非新合成的信号分子，很可能以无活性方式组成性表达于静息SEB应答〓细胞胞浆，在超抗原SEB再次刺激诱导〓细胞凋亡早期，先后顺序活化，借以传递凋亡信号到下游信号分子，诱导〓细胞凋亡。

Many methods for making nanoscale materials were developed in the past few years, such as colloidal crystallization, monolayer deposition, multiplayer casting, molecular crosslinking, complementary interaction, patterned etch pits, template-mediated and DPN, most of these are complicated and costive.

在过去的几年中，合成纳米复合材料的方法已取得了极大的进展，如胶体结晶法、单层膜沉积法、多层膜浇铸法、分子交联法、互补反应法、图形刻蚀法、模板化学法、DPN法等，但是这些方法大多操作耗时、费力。

Three potential initiation processes were identified during the cumyl phenyl dithioacetate mediated acrylate polymerizations.

三个可能的启动过程期间，没有发现基苯基dithioacetate介丙烯酸聚合。

In spite of this, the preparation of thiol-end functionalized PMMA was achieved by introducing a short block of polystyrene after the RAFT polymerization of MMA.Third, RAFT technique was applied to design and synthesize some well-defined poymers. Five monomers, lauryl methacrylate,(N,N-dimethylamino)ethyl methacrylate, poly methyl ether methacrylate, 4-(4\'-cyanobiphenyl-4-yloxy) butyl methacrylate and 2-ethyl methacrylate were chosen to RAFT homopolymerization or copolymerizations mediated by cumyl dithiobenzoate.

RAFT方法在具有特定结构聚合物的设计与合成上的应用，在机理研究的基础上，本论文选择五种不同结构的甲基丙烯酸酯类单体：lauryl methacrylate，(N，N-dimethylamino)ethyl methacrylate，polymethyl ether methacrylate，4-(4'-cyanobiphenyl-4-yloxy)butyl methacrylate和2-ethyl methacrylate，用CDB调控RAFT聚合的方法设计合成了一些特定结构的聚合物，详细而深入地研究了它们的均聚、共聚动力学，发现了双硫酯并非在聚合反应初期就全部转化，而是随着反应进行逐步消耗，这与理想的活性聚合体系有很大差别。
