Fibulin-5/DANCE is essential for elastogenesis in vivo.

The elastic fibre system has a principal role in the structure and function of various types of organs that require elasticity, such as large arteries, lung and skin. Although elastic fibres are known to be composed of microfibril proteins (for example, fibrillins and latent transforming growth factor (TGF)-beta-binding proteins) and polymerized elastin, the mechanism of their assembly and development is not well understood. Here we report that fibulin-5 (also known as DANCE), a recently discovered integrin ligand, is an essential determinant of elastic fibre organization. fibulin-5-/- mice generated by gene targeting exhibit a severely disorganized elastic fibre system throughout the body. fibulin-5-/- mice survive to adulthood, but have a tortuous aorta with loss of compliance, severe emphysema, and loose skin (cutis laxa). These tissues contain fragmented elastin without an increase of elastase activity, indicating defective development of elastic fibres. Fibulin-5 interacts directly with elastic fibres in vitro, and serves as a ligand for cell surface integrins alphavbeta3, alphavbeta5 and alpha9beta1 through its amino-terminal domain. Thus, fibulin-5 may provide anchorage of elastic fibres to cells, thereby acting to stabilize and organize elastic fibres in the skin, lung and vasculature.     

2004-2005赛季NBA常规技术统计与特点分析

应用关联分析和B型关联分析对NBA比赛中的13项技术指标进行了数据分析．结果表明，从总体作用上看，命中率因子对于比赛的最终结果影响较大，但从作用的稳定性上看，除投篮命中率外，罚球次数、后场篮板球、盖帽等技术对获胜也有着相当稳定的贡献．同时，通过对分类技术因子的关联分析阐述了进攻、防守和失误之间的相互关系，从而对提高或避免其它有利或不利技术指标有一定的借鉴作用．

植物药超氧物歧化酶活性与某些性质的研究

应用NBT光还原法对23种植物药材SOD粗提液活性研究表明。供试材料全部达到200units·g~(-1)F·W的水平,13种超过300units·g~(-1)F·W,野山楂高达812.5units。酶的比活,玄参、何首乌位列前茅,超过300units·mg~(-1)protein~-,野山楂、枸杞等都在150units·mg~(-1)protein~(-1)以上。综合分析,何首乌、野山楂、玄参与枸杞等酶活性与比活都高,有开发利用的价值。植物药普遍具有Mn-SOD与Cu·Zn-SOD,本研究首先发现枸杞、宁夏枸杞、沙参和合子草具有Fe-SOD。酶粗提液的热稳定性明显优于纯化酶。     

域外奇点法分析薄板的平面应力问题

本文推导了两边简支无限长薄板平面应力问题的基本解，该基本解为级数解，为了便于应用和提高计算精度，还求出了这些级数的和函数。把该基本解应用在域外奇点法中可分析一对边简支另一对边为任意的矩形薄板的平面应力问题。本文给出的算例表明该法有计算量少、精度高的优点。
