丙酮酸氧化酶既能被两性脂类激活,也能被蛋白酶从羧基端切下一个23肽(称α-肽)激活,而且这两种激活方式相互排斥。本文用分离纯化的α-肽,通过测定色氨酸荧光能量转移的方法,证明α-肽能与磷脂囊(vesicle)结合。我们选用两种不同类型的荧光探针,发现α-肽对它们表现不同的色氨酸能量转移效率。α-肽对Dan-syl-DppE为7.4±1.0％对Dansyl-UApC为12.5±2.0％。由此推测α-肽的色氨酸残基易与磷脂双层内部疏水区结合,说明α-肽是一种较为疏水的肽。我们推测α-肽在这种外膜酶的激活过程中,提供了与膜结合的部位,在生理过程中起着重要作用。

Jour.al of Tr.nspor.ation Technologies 2015年第3期5卷 159-168页

作者： Mar.us hager Jochen Seitz Thomas Waas Fachgebiet Kommunikationsnetze Technische Universit&auml t Ilmenau Ilmenau Germany Labor.Computer.etzwer.e Ostbayrische Technische Hochschule Regensburg Regensburg Germany

The vehicular.ad hoc networ. (VANET) technology based on the appr.ved IEEE 802.11p standar. and the appendant inter.vehicle communication (IVC) has the potential to dr.matically change the way tr.nspor.ation systems wor.. The fundamental idea is to change the individual behavior.of each vehicle by exchanging infor.ation among tr.ffic par.icipants to r.alize a cooper.tive and mor. efficient tr.nspor.ation system. Cer.ainly, the evaluation of such systems is a compr.hensive and challenging task in a r.al wor.d test bed, ther.for., simulation fr.mewor.s ar. a key tool to analyze IVC. Sever.l models ar. needed to emulate the r.al behavior.of a VANET in all aspects as much r.alistically as necessar.. The intention of this sur.ey is to pr.vide a compr.hensive over.iew of publications concer.ing IVC simulations of the year.2013 and to see how IVC simulation has changed since 2009. Based on this analysis, we will answer.the following questions: What simulation techniques ar. applied to IVC? Which aspects of IVS have been evaluated? What has changed within five year. of IVC simulations? We also take a closer.look at commonly used softwar. tools and discuss their.functionality and dr.wbacks. Finally, we pr.sent open questions concer.ing IVC simulations.

Objective: To deter.ine the association of apoptosis in the layer. of human fetal membr.nes distal to r.ptur. site with labor.at ter.. Study Design: Fetal membr.nes wer. collected fr.m elective cesar.an sections (n = 8) and spontaneous vaginal deliver.es (n = 8) at ter.. The extent of apoptosis within fetal membr.ne layer. was deter.ined using ter.inal deoxynucleotidyl tr.nsfer.se deoxy-UTp-nick end labeling (TUNEL) assay and wester. blots for.pr.-apoptotic active caspase-3 and anti-apoptotic Bcl-2. r.sults: Apoptotic index in chor.onic tr.phoblasts of membr.nes distal to r.ptur. site obtained after.vaginal deliver. was 3-fold higher.than those obtained fr.m elective cesar.an (11.57% ± 4.98% and 4.05% ± 2.4% r.spectively;p = 0.012). The chor.odecidua layer. after.vaginal deliver.es had higher.expr.ssion of the pr.-apoptotic active caspase-3 and less expr.ssion of the anti-apoptotic Bcl-2 than those obtained fr.m elective cesar.an sections. Conclusions: Labor.at ter. is associated with incr.ased apoptosis in chor.onic tr.phoblast cells of human fetal membr.nes distal to r.ptur. site.
