2英文T恤切莫傻穿显示文摘随着2008年奥运会的逼近,民众越来越关心“中国”品牌的树立,学习英语的热情也被点燃。越来越多的外宣干部和业内同行向我们表达了期待看到双语栏目的期望。因此,我们在2006 年第一期开办《双语视窗》栏目满足广大读者的需求。看看周围的媒体,《北京青年报》、《参考消息》、《国门时报》上有许多精粹的小短文,像一只只啄木鸟,善意地提醒了中国人习以为常的行为背后“尚未和国际接轨”的细节,读后让人回味不已,在获得借鉴意义的同时,也带来更深入的思考。我们效仿中英文对照的版面形式,旨在通过外国友人的视角来看中国, 从中折射出东西方观念、习俗的异同。通过一篇篇这样的文章, 让读者在领略异域文化的同时,也能达到学习英语的目的。David Tool 2006对外传播2006,0,6:2
3Axial strain enhances osteotomy repair with a concomitant increase in connexin43 expression显示文摘The mechanical environment is known to influence fracture healing. We speculated that connexin43(Cx43) gap junctions, which impact skeletal homeostasis, fracture healing and the osteogenic response to mechanical load,may play a role in mediating the response of the healing bone to mechanical strain. Here, we used an established rat fracture model, which uses a 2 mm osteotomy gap stabilized by an external fixator, to examine the impact of various cyclical axial loading protocols(2%, 10%, and 30% strain) on osteotomy healing. We examined the presence of Cx43 in the osteotomy-healing environment and assessed how mechanical strain modulates Cx43 expression patterns in the callus. We demonstrated that increased cyclical axial strain results in increased radiographic and histologic bone formation. In addition, we show by immunohistochemistry that Cx43 is abundantly expressed in the healing callus, with the expression most robust in samples exposed to increased cyclical axial strain. These data are consistent with the concept that an increase in Cx43 expression by mechanical load may be part of the mechanisms by which mechanical forces enhances fracture healing.Rishi R Gupta Hyunchul Kim Yu-Kwan Chan Carla Hebert Leah Gitajn David J Yoo Robert V O’Toole Adam H Hsieh Joseph P Stains 2015Bone Research2015,3,2:2
