The major results of this proposal are as follows:(1) ABA induces a rapid, substantial accumulation of apoplastic H2O2 in mesophyll and bundle sheath cells of maize leaves, and the accumulation of apoplastic H2O2 is involved in the induction of the chloroplastic and cytosolic antioxidant enzymes.(2) ABA-induced H2O2 production activates a 46 kDa MAPK, which in turn induces the expression of antioxidant genes and up-regulates the activities of antioxidant enzymes. The activation of MAPK also enhances H2O2 production, forming a positive amplification loop.(3) Water stress also induces the activation of a 46 kDa MAPK, which is dependent on the accumulation of ABA and H2O2 production induced by water stress and involved in the up-regulation of the expression and the activities of antioxidant enzymes.(4) ABA-induced H2O2 production mediates NO generation, which in turn activates a 46 kDa MAPK and results in the up-regulation in the expression and the activities of antioxidant enzymes in ABA signaling. NO-independent signaling is also involved in ABA- and H2O2-induced antioxidant defense.
本项目的主要研究结果如下:(1)ABA诱导的H2O2产生主要出现在叶肉细胞与维管束鞘细胞的质外体中,质外体H2O2的积累能够上调叶绿体与细胞溶质中抗氧化酶的活性;(2)ABA诱导的H2O2产生活化一个46kDa的MAPK,由此而导致编码抗氧化防护酶基因的表达与酶活性的上调;而MAPK的活化也能增强H2O2的产生,从而形成一个正的反馈调节环;(3)水分胁迫也能诱导一46kDa MAPK活化,这一MAPK活化依赖于水分胁迫诱导的ABA积累以及H2O2的产生,同时参与水分胁迫诱导的抗氧化防护基因的表达与抗氧化酶活性的上调;(4)ABA诱导一个依赖于H2O2的NO产生,NO活化一个46kDa的MAPK,从而导致抗氧化防护基因的表达以及抗氧化酶活性的上调;同时一个不依赖于NO的信号转导途径也存在于ABA诱导的抗氧化防护过程中。

Majority of acute leukemias in infant, either acute lymphoblastic leukemia or acute myeloblastic leukemia, posses a chromosomal translocation affecting the 11q23 chromosome region which specifically inoles the mixed-lineage leukemia gene.1-3 Most pediatric leukemias with MLL rearrangement clearly hae a remarkably short latency.1,4 MLL gene rearrangement is also associated with secondary leukemias of patients preiously treated with the topoisomerase II inhibitors.4 The latency of these secondary leukemias is similarly ery short.4 Of note, the concordance rate of leukemia with MLL rearrangement in infant monozygotic twins approximates to 100%,1,4 and identical breakpoint in the MLL gene was shared in these pairs of identical twin infants with concordant ALL.1,4 Moreoer, the unique and clonotypic MLL fusion gene was detectable in neonatal blood spots for Guthrie cards from non-twined indiiduals who subsequently deeloped ALL.1,4 These obserations indicate not only that MLL fusion is generated in utero but also that MLL fusion proteins could be capable of inducing leukemic transformation with few, if any, secondary mutations.2,3,4 Greaes et al speculate that an MLL fusion protein somehow promotes rapid transition to full-blown disease in patients ia ery rapid clonal expansion, genetic instability, or inhibition of DNA damage repair.4 In general, for clonal expansion of malignancies, tumor cells often hae acquired strategies that escape immune sureillance of the hosts.5,6 Immune escape mechanisms also contribute to the failure of graft-ersus-leukemia effect after allogeneic hematopoietic stem cell transplantation.7 Therefore, leukemia cells could acquire some immune escape mechanisms during leukemogenesis.
绪论 绝大多数的婴儿白血病,不管是急性淋巴性白血病或是急性骨髓性白血病,在染色体11q23部位有染色体易位的情况;这个部位的染色体易位牵连了混合谱系白血病基因。大多数具有MLL基因重排的儿童白血病潜伏期明显短很多。MLL基因重排也和经拓扑异构酶II抑制剂治疗后的继发性白血病有关。这些继发性白血病的潜伏期类似地都非常的短。很重要的是,单卵双胞胎婴儿同时患有或同时免于MLL基因重排阳性的白血病的一致性接近100%;并且同样患有ALL的同卵双胞胎的MLL基因的断裂点是一致的。而且,这种独特的克隆特异性的MLL融合基因能够从那些得ALL的非双生个体出生时的血斑标本中检测到。这些发现表明MLL融合基因产生在胎儿还在子宫的是后,而且MLL融合蛋白能过和其他的基因突变一起诱导白血病的产生。Greaes 等推测MLL融合蛋白在某种情况下同过快速克隆增殖,遗传的不稳定性或是DNA损伤修复的抑制促使疾病迅速地全面爆发。恶性肿瘤细胞的克隆增殖通常已经获得了逃避机体免疫监视的能力。免疫逃避机制也归因于异体外周血干细胞移植后移植物抗白血病作用的失效。所以,白血病细胞在白血病的产生过程中可能获得了某些免疫逃脱机制。

Although Arendt did not articulate a dear solution to these problems, she still offer us a specific access to them by analyzing the phenomena which have already existed in the political sphere such as ideological tenor, the end of the Rights of Man, lies, violence, hypocrisy, guilt, evil, and by examining the conceptions such as the natality and the plurality of human-beings, the capacity of actions and thinking, and the sensus communis. She not only argued for the unique of Man but also emphasized the human-beings in the plural sense; Her formulation of her anti- totalitarianism thought not only demonstrated her guard against the possible invasion of the private space made by the public space, but also shows u s her yearning for the re-birth of the public realm; Her inclination to classical republicanism not only echoes the ancient Greek spirit, but also can be interfused into the contemporary philosophical context.
她虽然没有给出一个针对上述问题的清晰答案,但是,她仍然通过对于政治领域中业已存在着的诸种现象--如意识形态恐怖、人权的丧失以及谎言、暴力、伪善、罪恶等一的分析,并通过对于人的&必然诞生&、人的复数性、人的行动能力、思考能力以及判断力、人的共同感等概念的梳理,提供了一个针对上述问题的独到的思考视角;她既论证了人的存在的独特性和不可替代性,但同时也复数意义上的人作了强调;她对于反极权、反强权思想的理论阐述,既表明了她对于私人领域之遭受公共领域与大众社会侵蚀的警惕,同时更表明了她对于公共领域之再生的关心;她的古典共和主义的倾向,既与古希腊精神遥遥相应,又切中了由当代现实问题所引发的诸多理论关切。

The following exciting results are revealed: 1 When considering the influence of some nonlinear elements such as hard-limit of exciters, the effects of some devices such as Power System Stabilizer and Static Var Compensator which can introduce positive damping in power system, the reasonability of system parameter values in simulation, the SNB surface and HB surface on the boundary of SSSR will turn close to each other and even coalesce together; 2 Under some conditions, coupling between slow exciters and shunt capacitors will bring negative damping in power system dynamics, which increases the possibility of oscillatory instability. So the power system with mass shunt compensators is easily subjected to the oscillatory instability. In recent years, chaotic phenomena of power system have been reported many times. Some simulation studies even found chaos existing inside the power system SSSR. In this dissertation, chaotic phenomena in power systems are thoroughly studied in order to make clear the relation of chaos and SSSR. The following results are derived: 1 Based on Li-Yorke Theorem and their definition on the chaos, the existence of chaos in power system is verified; 2 Three possible routes of causing chaos in power system are found and deeply investigated. They are route of cascading period doubling, route of directly initial energizing and route of torus bifurcation (or quasi-periodicity). The latter two routes are investigated for the first time in power system stability studies; 3 When the stability conditions of chaos are broken, it is found they can lead to voltage collapse, angle divergence, or voltage collapse with angle divergence simultaneously.
针对在电力系统小扰动稳定区域内可能存在混沌吸引域的有关报道,本文深入研究了电力系统混沌现象的出现途径和与系统失稳模式之间的关系:1利用Li-Yorke定理和Li-Yorke的混沌定义,从理论上证明了电力系统混沌现象的存在性;2发现了电力系统中导致混沌出现的三种可能途径:倍周期分岔导致混沌、初始能量直接激发混沌和经由环面分岔导致混沌,并对后两种新发现的途径进行了较为细致的研究;3发现了混沌极限环破裂导致电压崩溃、角度失稳以及电压崩溃和角度失稳同时出现的现象,其中混沌极限环破裂导致系统角度失稳和电压崩溃及角度失稳同时出现的现象均属首次报道;4证明由微分-代数方程描述的系统模型,其小扰动稳定域的边界只包含HB、SNB和SIB三种分岔界面,在SSSR的内部和边界上,均不可能存在会导致混沌的点,从而将混沌现象排除在小扰动稳定域的研究之外,简化了后者的研究工作。
