| 2 | Twenty-five years of research on the effects of exercise training in breast cancer survivors:A systematic review of the literature显示文摘AIM:To investigate the role of exercise training the past 25 years on major physiological-psychological outcomes studied thus far in this patient population.METHODS:Pub Med, Medline Plus, the Cochrane Library, Web of Science, SportD iscus, Embase, Scorpus, and Google Scholar were searched from September to November 2013 to identify exercise training studies that used objective measurements of fitness and/or patient reported outcomes assessed pre and post-exercise training with statistical analyses performed in at least one of the following outcome measurements:Cardiorespiratory function, body composition, muscular strength, fatigue, depression, and overall quality of life. Five reviewers independently identified the studies that met the criteria for the review and discrepancies were resolved by consensus among all authors.RESULTS:Fifty-one studies were included in this review with 5 from the period between 1989-1999, 11 from 2000-2006, and 35 from 2007-2013. The evolution of study designs changed from aerobic only exercise training interventions(1989-1999), to a combination of aerobic and resistance training(2000-2006), to studies including an arm of resistance training or examining the effects of resistance training as the main mode of exercise(2007-2013). Overall, the benefits of exercise showed improvements in cardiorespiratory function, body composition, strength, and patient reported outcomes including fatigue, depression, and quality of life.CONCLUSION:Exercise training appears to be safe for most breast cancer patients and improvements in physiological, psychological, and functional parameters can be attained with regular participation in moderate intensity exercise. | Claudio L Battaglini Robert C Mills Brett L Phillips Jordan T Lee Christina E Story Marcelo GB Nascimento Anthony Carl Hackney | 2014 | World Journal of Clinical Oncology2014，5，2： | 3 |
| 3 | 一种直列式6缸发动机主轴承盖的开发显示文摘将粉末冶金用于铝合金发动机汽缸体意味着对材料切削加工性能的一种挑战。除了要求静态与疲劳强度之外,为了能够对发动机汽缸体组件进行有效地镗孔,材料的切削加工性状还必须和铝合金相容。为了满足这项应用提出的要求,开发了含有六方氮化硼的粉末配方。这项重要发展包括材料选择、切削性评价,以及静态与动态强度试验。为确定轴承盖最关键的部位进行了有限元分析(FEA)。轴承盖是在经过金相检验、尺寸变化测定、静态与疲劳试验之后,进行制造与鉴定的。对制造工艺提出并实行了一些改进。轴承盖顺利地进行了切削加工,并通过了用户的发动机试验。此后,这些轴承盖在数以百万件计地进行生产。 | Edmond Ilia Mike O’Neill Jordan Lee Joel Poirier Sylvain St-Laurent 韩凤麟 | 2007 | 粉末冶金技术2007，25，4： | 2 |
