Electroosmotic water vapor transport (WVT) across very thin, flexible, functionalized conducting polymer (CP) microporous (μP) membranes at a very high rate is reported. Both passive and active (6 VDC applied) WVT are reported, the latter for the first time ever. WVT occurs with concomitant, effective blocking of chemical warfare (CW) agents, again demonstrated for the first time ever. Initial active liquid||membrane||liquid interface studies demonstrated WVT rates of >1.7 × 10-5g .mm-2s-1, >3 × the highest prior reported values of 5 × ***-2s-1. Subsequent vapor||membrane|| vapor interface studies using industry-standard methods (including ASTM E96B Upright Cup (“WVT”), ASTM F2298 (“Dynamic Moisture Permeation Cell”) and ASTM F1868 (“Sweating Guard Hotplate”) were done at independent, external labs for independent corroboration. These yielded, e.g., WVT values of2564.4 g.m2.d-1 (passive) and3706.7 g.m2d-1 (active), to be compared with the highest (passive) value ever reported previously,984.8 g.m2.d-1 for a μP-Nylon membrane. More than 15 different membrane configurations, porosities and types were studied, including membranes with CP + organophosphate hydrolase (OPH), an enzyme reactive to CW agents. Efficient blocking of the actual CW agents GB, HD, VX is also reported, using the TOP-8-2-501standard. Membranes also passed all Industry-standard durability tests, e.g. ASTM D2261 (Tearing), ASTM D5034 (Breaking), ASTM D3886 (Abrasion), ASTM F392 (Gelbo Flex). Incorporation into smart soldiers’ garments was demonstrated;power consumption was -2. Mechanisms of enhanced WVT and CW agent blocking in the membranes are discussed.

Antiviral warrior—APOBEC3G

引用

Journal of Electronic science and Technology of China 2005年第4期3卷 372-376页

作者：吴小霞马义才 School of life science and technology University of Electronic Science and Technology of China Chengdu 610054 China

This paper is to further understand how APOBEC3G can defend the retroviruses and to find new approaches to AIDs （acquired immure deficiency syndrome）.The viral infectivity factor （Vif） induces rapid degradation of APOBEC3G by ubiquitination, which is a proteosome-dependent pathway. Precisely speaking, only in the virus-producing cell Vif expression is necessary; in its absence, infection of a subsequent target cell terminates at a postentry step through the action of the human APOBEC3G antiviral mechanism. Hf protein has two domains： one binds to APOBEC3G and the other regulates the degradation of APOBEC3G by a conserved sequence, SLQ （Y/F） LA motif. Recently, the research on Vif has also revealed APOBEC3G is a novel component of innate immune system. In fact, APOBEC3G not only acts in DNA editing to block the replication of retroviruses such as HIV-1, but also is able to defend a wide spectrum of distantly related retroviruses and interferes with HBV through a different mechanism from HIE.

Man, City, and Nature in The Woman warrior and Ballad of Eternal Sorrow

引用

Sino-US English Teaching 2014年第7期11卷 547-552页

作者： QIU Shi-cun JIANG Deng-ke Southwest University Chongqing China Sichuan University of Arts and science Dazhou China

In a time of the global market economy, if one wants to live harmoniously together with nature or living environment, he should not think with a theoretical mode of dualist contradiction but that of harmony and coexistence such as ＂wholeness of man and nature＂. To illustrate this point, this paper thinks The Woman warrior and Ballad of Eternal Sorrow are two significant texts： Ballad of Eternal Sorrow tells an ordinary, self-respecting, and life-respecting story of WANG Qi-yao and the girls like her as well as the city Shanghai. They blend into one harmonious whole： The city is like the girls and the girls match the city. Likewise, The Woman warrior highlights the significance of naturc on the girl narrator＇s epiphany and healthy growth. The narrator comes to understand that paradoxes are the basic existent condition of human beings and so what she needs to do is to be magnanimous and balanceable in accepting these paradoxes.
