猪瘟病毒E2蛋白B细胞识别基序的筛选

根据猪瘟病毒(classical swine fever virus,CSFV)E2蛋白的序列设计并人工合成18条重叠多肽,与载体蛋白BSA偶联后,利用抗CSFV E2蛋白单克隆抗体SWmAb8筛选该蛋白上的B细胞表位;同时用12肽噬菌体随机肽库淘选E2单抗识别多肽序列。结果显示,多肽序列VSPTTLRTEV能被单抗SWmAb8识别;含SPTxLR基序的噬菌体能被单抗SWmAb8结合,且能被病毒抗原竞争性抑制。证实SPTxLR基序很可能是E2蛋白的线性表位之一,可诱导机体产生中和抗体。

大鼠挫伤骨骼肌中M1/M2型巨噬细胞时间相关性研究

目的研究大鼠骨骼肌挫伤后M1/M2型巨噬细胞浸润的动态变化规律结合组织学改变建立损伤时间推断方法。方法建立大鼠骨骼肌挫伤模型,挫伤后6h、12h、24h、36h、48h、60h、72h、96h、144h、216h、336h为实验组,对照组不进行任何处理。采用HE染色法和免疫荧光多重染色方法观察骨骼肌挫伤后修复规律,运用全景组织细胞定量分析系统检测损伤区内单位面积细胞核数量、M1及M2型巨噬细胞数量和比例变化规律并建立与损伤时间的关系。结果在0.5mm×0.5mm范围内,M1型巨噬细胞比例在0.05±0.02~0.18±0.12且M2型巨噬细胞比例在0.02±0.01~0.04±0.02范围内时,推断该组织的损伤时间为伤后6h~48h;M1型巨噬细胞比例0.22±0.02且M2型巨噬细胞比例在0.09±0.02范围内时,推断该组织的损伤时间为损伤后60h;M1型巨噬细胞比例0.1±0.02且M2型巨噬细胞比例在0.16±0.07范围内时,推断该组织的损伤时间为损伤后144h;M1型巨噬细胞比例0.05±0.01~0.09±0.02且M2型巨噬细胞比例在0.07±0.02~0.09±0.01范围内时,推断该组织的损伤时间为损伤后216h~336h。结论大鼠挫伤骨骼肌中M1/M2型巨噬细胞时间相关性表达规律可作为损伤时间推断的新依据,结合病理组织学改变可进一步提高损伤时间推断的准确性。

Russia: A Country with an Unpredictable Past

Russia is a key player in the Kyoto process, and the fate of the Protocol itself heavily depends on future developments in the country, in particular in its energy sector. This article analyses the contradictory and complex relationships between carbon dioxide emissions, gas exports to Western Europe and the energy security of Russia. The paper reviews emerging trends in the energy sector of Russia that will have a long-term impact on these three parameters and assesses the possible influence of these trends on the implementation of the Framework Convention on Climate Change and the Convention on Long-range Transboundary Air Pollution in Russia. Proceeding from the latest developments in the Russian energy scene, the author tries to forecast how Russia will integrate into the international community in the energy sphere. The study concludes that gas export commitments to Europe will be met despite the serious problems in the domestic gas sector, that energy saving in Russia is the most feasible way of finding a compromise between the three parameters, and that enhancing the energy security of Russia might have rather controversial consequences for Europe.     

猪链球菌2型多重PCR快速检测方法的建立

Kündigungsverzicht des Mieters bei unbefristetem Mietvertrag

Die analoge Anwendung des § 29 Abs 2 MRG auch auf unbefristete Mietvertr?ge, in denen der Mieter einen Kündigungsverzicht erkl?rt hat, würde bedeuten, die Zul?ssigkeit bzw Wirksamkeit eines Kündigungsverzichts des Mieters überhaupt zu verneinen. Dies w?re aber eine Abkehr von der bisherigen Rsp, die einen derartigen Kündigungsverzicht – von wem immer er auch abgegeben wurde – als wirksam erachtet.     

Political accountability,fiscal conditions and local government performance—cross‐sectional evidence from Indonesia

Why are some local governments more successful than others in managing resources and delivering services? And even more vitally, how can malfunctioning governments be reformed so that they perform their responsibilities more effectively? This article contributes to our understanding of theses overarching questions by exploring the interactions between political institutions and public sector performance in the context of decentralisation and local governance. It shows–both theoretically and empirically–that performance outcomes are determined by the extent to which people can hold their governments accountable through political institutions. The basic hypothesis underlying this research is that political accountability, either by encouraging sanctions upon non‐compliant public agents or simply by reducing the informational gap regarding government activities, will create forceful incentives for elected officials and civil servants to reduce opportunistic behaviour and improve performance. Using a cross‐sectional regression the hypothesis is empirically tested against evidence from newly empowered local governments in Indonesia. The empirical findings broadly support our hypotheses. Improved public services on the ground, both in terms of quantity and quality, require informed and well functioning decision‐making processes that allocate resources to priority areas that meet the demand of the broader community.
