这是乔科维奇在温网中心球场留下的最后一幕,高举金杯,嘴里说着“叶莲娜·戈西奇”。他知道如果没有那个女人教会他人生哲理以及网球,此刻他不可能以一个冠军甚至是塞尔维亚国民英雄的身份站在那里。 相似文献

非洲广大地区由于采采蝇的蔓延,引起锥虫病,对畜牧生产十分不利。目前在这方面的策略仍是减少病害的影响,其中包括采用药物治疗病牛和繁殖抗病良种等。最近的研究表明,繁殖良种的潜力比以前预计的要大,并且由于结合控制采采蝇,使用药物和繁殖抗锥虫牲畜,因此就可能使锥虫影响大大下降,并使采采蝇蔓延地区能够进行畜牧生产。 相似文献

父亲并非一个天资过人的人。如果说模范父亲应该既能蘑装剪草机、上拳袋、教给孩子科学课的技巧或如何获得救生奖章另外还能指导孩子数学家庭作业,把一辆新自行车装起来或更换露台门纱窗的话,那么我的父亲算不上一个模范父亲。 相似文献

Tissue homeostasis requires a carefully-orchestrated balance between cell proliferation, cellular senescence and cell death. Cells proliferate through a cell cycle that is tightly regulated by cyclin-dependent kinase activities. Cellular senescence is a safeguard program limiting the proliferative competence of cells in living organisms. Apoptosis eliminates unwanted cells by the coordinated activity of gene products that regulate and effect cell death. The intimate link between the cell cycle, cellular senes- cence, apoptosis regulation, cancer development and tumor responses to cancer treatment has become eminently apparent. Extensive research on tumor suppressor genes, oncogenes, the cell cycle and apoptosis regulatory genes has revealed how the DNA damage-sensing and -signaling pathways, referred to as the DNA-damage response network, are tied to cell proliferation, cell-cycle arrest, cellular senescence and apoptosis. DNA-damage responses are complex, involving “sensor” proteins that sense the damage, and transmit signals to “transducer” proteins, which, in turn, convey the signals to numerous “effector” proteins implicated in specific cellular pathways, including DNA repair mechanisms, cell-cycle checkpoints, cellular senescence and apoptosis. The Bcl-2 family of proteins stands among the most crucial regulators of apoptosis and performs vital functions in deciding whether a cell will live or die after cancer chemotherapy and irradiation. In addition, several studies have now revealed that members of the Bcl-2 family also interface with the cell cycle, DNA repair/recombination and cellular senescence, effects that are generally distinct from their function in apoptosis. In this review, we report progress in understanding the molecular networks that regulate cell-cycle checkpoints, cellular senescence and apoptosis after DNA damage, and discuss the influence of some Bcl-2 family members on cell-cycle checkpoint regulation. 相似文献

点燃思维之火：开放教育，长尾理论和学习2．0 总被引：1，自引：0，他引：1
高等教育需求和服务供给的矛盾为基于新技术的学习模式提供了空间.基于实践社区支持,强调参与、建构和兴趣驱动的社会化学习等非正式学习开始从边缘走向中心.本文讨论技术支持下的学习模式变革,强调整合社区支持和资源共享的重要性,从学习知识(Learn about)向学会生存(Learn to be)转变,并指出以资源共享为主的开放教育资源在社区支持方面的薄弱.开放教育资源的价值在学习的长尾中得到了揭示和体现,而建立社区与共享资源同样重要.通过建立参与性学习生态系统,推动从Web2.0发展到Learning2.0. 相似文献
