| 5 | 肥大细胞源性组织蛋白酶G在狭窄主动脉瓣不良改变中的可能作用显示文摘Aims: Aortic stenosis(AS) is characterized by extensive remodelling of the valves, including infiltration of inflammatory cells, extracellular matrix degradation, and fibrosis. The molecular mechanisms behind this adverse remodelling have remained obscure. In this article, we study whether cathepsin G, an angiotensin Ⅱ(Ang Ⅱ)forming elastolytic enzyme, contributes to progression of AS. Methods and results: Stenotic aortic valves(n=86) and control valves(n=17) were analysed for cathepsin G, transforming growth factor-β1(TGF-β1), and collagens I and Ⅲ with RT-PCR and immunohistochemistry. Valvular collagen/elastin ratio was quantified by histochemistry. In stenotic valves, cathepsin G was present in mast cells and showed increased expression(P< 0.001), which correlated positively(P< 0.001)with the expression levels of TGF-β1 and collagens I and Ⅲ. TGF-β1 was also present in mast cell rich areas and cathepsin G induced losartan-sensitive TGF-β1 expression in cultured fibroblasts. Collagen/elastin ratio was increased in stenotic valves(P< 0.001) and correlated positively with smoking(P=0.02). Nicotine in cigarette smoke activated mast cells and induced TGF-β1 expression in cultured fibroblasts. Fragmented elastin was observed in stenotic valves containing activated cathepsin G-secreting mast cells and in normal valves treated with cathepsin G. Conclusion: In stenotic aortic valves, mast cell-derived cathepsin G may cause adverse valve remodelling and AS progression. | Helske S. Syvranta S. Kupari M. K.A.

| 6 | Stability of multiple fans in mine ventilation networks显示文摘In large mines,single fan is usually not enough to ventilate all the working areas.Single mine-fan approach cannot be directly applied to multiple-fan networks because the present of multiple pressures and air quantities associated with each fan in the network.Accordingly,each fan in a multiple-fan system has its own mine characteristic curve,or a subsystem curve.Under some consideration,the conventional concept of a mine characteristic curve of a single-fan system can be directly extended to that of a particular fan within a multiple-fan system.In this paper the mutual effect of the fans on each other and their effect on the stability of the ventilation network were investigated by Hardy Cross algorithm combined with a switching-parameters technique.To show the validity and reliability of this algorithm,the stability of the ventilation system of Abu-Tartur Mine(one of the largest underground mine in Egypt)has been studied. | El-Nagdy K.A. | 2013 | International Journal of Mining Science and Technology2013,23,4: | 6 |
| 7 | CAVITATION NUCLEI:EXPERIMENTS AND THEORY显示文摘The Swedish astrophysicist and Nobel Prize winner Hannes Alfvén said:Theories come and go─the experiment is here forever.Often a theory,which we set up to describe an observed physical phenomenon,suffers from the lack of knowledge of decisive parameters,and therefore at best the theory becomes insufficient.Contrary,the experiment always reveals nature itself,though at prevailing experimental conditions.With essential parameters being out of control and even maybe unidentified,apparently similar experiments may deviate way beyond our expectations.However,these discrepancies offer us a chance to reflect on the character of the unknown parameters.In this way non-concordant experimental results may hold the key to the development of better theories-and to new experiments for the testing of their validity.Cavitation and cavitation nuclei are phenomena of that character. | MφRCH K.A. | 2009 | Journal of Hydrodynamics2009,21,2: | 6 |
| 8 | 阿什河下游河湾地带考古调查收获显示文摘前言:当前在书面语言的运用方面存在着相当严重的问题。其原因除了十年动乱对语言的污染外,规范化工作本身也存在着亟待解决的问题,必须引起语言工作者的高度重视。一语言学家的作用:不同意“在语言的问题上,语言学家只能当顾问,最终的裁决权永远掌握在广大人民群众手中”这种观点,强调语言学家应当尽力发挥作为专家的主观能动作用。二语言问题的界限:“言语作品”中的问题并不都是语言问题。分清语言问题与非语言问题的界限,有助于我们集中目标,排除干扰,研究语言规范的原则和标准。三语言的规范和发展:规范是在发展中的规范,发展是在规范下的发展。有两种对现有规范的“突破”:有益的突破和无益的突破。前者是对语言的发展,后者是对语言的损害。我们要肯定前者,推广前者;否定后者,抵制后者。四原则和标准:准确和经济是信息传递的原则,即效率原则。我们根据这个原则结合汉语的特点,可以确定用以辨别两种“突破”的标准。按照标准对“词语搭配”“词性转变”“拆离词语”三种语言现象进行了具体分析;提出了处理不同的“突破”应该采取不同的方式。五几点建议:针对当前的情况提出了关于加强汉语规范化工作的具体措施的四点建议。 | K.A.热列兹涅柯夫 孙秀仁 | 1983 | 北方文物1983,,2: | 5 |
