利用RT-PCR方法扩增了猪ERK6基因编码区的序列,将扩增产物与pMD18-T载体连接,构建了重组质粒;重组质粒经PCR、酶切鉴定后进行测序;采用Northern杂交和半定量RT-PCR方法在猪不同部位骨骼肌中分析了ERK6基因转录本的个数、大小及组织表达谱。结果显示,所克隆的猪ERK6基因片段长1 113 bp,含有1个1 104 bp的开放阅读框(ORF),该ORF编码367个氨基酸;该基因与已报道的人ERK6基因核苷酸序列相似性为90%;猪ERK6基因在肌肉组织中只有一个转录本,大小约1.5 kb。此基因在骨骼肌中的表达量最高,心、子宫次之,卵巢最低;而在脂肪、胃、肝、脾、肺、肾、十二指肠和胰腺中未见表达。结果表明,猪ERK6基因与已报道的小鼠和人ERK6基因一样,主要在骨骼中特异表达。  相似文献

The concentration of thyreoglobulin (tg) was determined for death caused by hanging, strangulation by ligature, and throttling. Cases of sudden death (traumatic aortic rupture, penetrating wounds of the heart) were used for comparison. The mean values in cases of hanging (149.9±202.3 ng/ml), strangulation by ligature (193.1±173.3), manual strangulation (561.6±173.9) are distinguishable from violent acute deaths (23.3±27.6) and living healthy individuals (17.3±16.1). By means of statistical comparisons, significant differences were found between throttling and strangulation by ligature and between throttling and hanging (adjusted P<0.001). In connection with examination of the bodies high tg values can be regarded as a vital reaction in obstructive asphyxia.  相似文献

In the last decades, municipal mergers have been one major element of local government reforms in Switzerland and beyond. In this article, we describe and analyze the political effects of this development. We use a quasi‐experimental setting to test the impact of municipal mergers on electoral participation. We find that in merged municipalities, the decrease in turnout is significantly stronger than in non‐merged municipalities. Further, the effect is more pronounced in relatively small localities. There is a temporal dimension to this effect—that is, turnout drops mainly in the first election after the first merger, but not so much after the second or third merger. Hence, the study provides a skeptical yet differentiated perspective on the democratic consequences of municipal mergers and points to further research avenues to develop a more comprehensive understanding of local government consolidation.  相似文献

YANG Jie, 23, starts work at his office on Youth Road in Wuhan, Hubei Province at 9 am each day and returns to his dorm to sleep at 10 pm. He eats a modest lunch in the small restaurant downstairs and has a takeaway for supper. It was in the summer of 2005 that Yang Jie and Li Chao opened their Qi Hang Advertising Company. Their small firm deals with large and small concerns alike, and in order to stay solvent, they spend their lives either at the office, where they deal with clients an…  相似文献

二战结束至今,日朝之间仍未建立外交关系,因此,两国又被称作“近而远的国家”。目前,战争赔偿问题、日本人绑架问题、导弹发射及出售问题已成为日朝恢复邦交关系的一些障碍因素。尤其是朝核问题成为今后相当长一段时期影响日朝关系的一个主要因素。  相似文献

International experience shows that the main objective of New Public Management (NPM) reform has predominantly been to overcome the current crisis in funding and public service delivery. The achieving this objective has involved adopting a philosophy of 'more for less' or, in other words, by enhancing 'value for money' in public service delivery. To this end,NPM reforms have generally aimed at replacing the inherited or traditional bureaucratic structure of management with a market – or at least a competition-based – contract arrangement. As is the case in any contested market setting, the main concern of state and public administration is no longer merely to ensure a legally correct application of laws, but also to use scarce resources as 'efficiently' as possible in the pursuit of the desired ends of increased productivity and 'more for less'.  相似文献
