Focusing on the roles of progressive telomere deprotection in cells approaching replicative senescence, we discovered that critically short telomeres signal differently than intrachromosomal DNA breaks.Telomeres in an intermediate-deprotected presenescent state, which are recognized by the DNA damage machinery but still protected against end-to-end fusions, do not activate the G2 checkpoint response dependent on Chk2 phosphorylation and signaling.

目的:本研究拟根据推拿课程教学大纲的要求,制定出一套具有较好科学性、客观性及可操作性的考核评分标准及方法,以期达到能客观、公正地评价出学生对推拿手法的实际掌握程度的目的.同时,为其他需要实践性环节考核的课程提供有益的经验.方法:选取保健按摩推拿技术为考核内容.规定学生必须在规定时间内完成两个不同部位的推拿治疗操作演示,由考核评判员从手法基本技术和实际运用能力两方面对推拿操作技能水平进行评判.确定"
慕课(MOOC,Massive Open Online Course)即"大规模网络开放课程",是一种基于网络而进行交流、协作和知识发现的学习文化,既代表着一种新型技术系统,也蕴含着一种新型教学模式。慕课是全球化信息化时代的教育趋势,目前,我国"慕课"建设虽正处于起步和摸索阶段,然而,我国高校已开始打造众多学科的"慕课"平台,"慕课"已在根本上开始触动传统高等教育的根基,可能引起大学重新洗牌,终形
运动生物化学是生物化学在体育科学领域中应用的分支学科,是体育教育、运动训练和民族传统体育专业学生必修课之一。探讨该课程教学中存在的问题及开展教学改革,对于学生掌握和理解运动人体科学的知识具有重要实践意义。研究方法:通过文献资料、访谈及师生的课堂实践,分析教学中存在的若干问题,并对存在的问题结合教学实践,从改进教学方法、激发学生的学习兴趣以及提高教师素质等方面来探讨提高运动生物化学教学效果的方法,使
当前运动人体科学专业的实践教学内容简单化、实践教学体系碎片化、实践教学地位依附化、实践教学环境封闭化、实践教学效果难以满足社会需求。采取目标驱动、内容互补、内外联动、基地分类、双师培养、双证认证、导师配置、三方评价等改革措施,构建"基础实践、校内校外实训、专业实习和社会实践三个阶段,内外联动的实践教学模式",培养"通识知识储备、专业基础技能、职业发展素养"三位一体化的能力,建立产学研三位一体化的合
目的:目前,运动人体科学专业学生作为体育健康产业专业人才,虽有较好的理论功底,但对行业认识不够,实践能力有待加强,因此很有必要开展校企协同育人模式研究。本研究主要就校企协同应用型创新人才培养模式进行研究,探索与实践运动人体科学专业与健康相关行业和企业协同育人的体制机制和运作模式,最终协同培养出应用型、创新型、复合型和技能型的运动人体科学专业高层次人才,从而促进体育健身产业发展和全民健身科学化。
