“Déjà vu” was my impression of the Hanoi Summit. North Korean leaders simply cannot make real steps towards denuclearization. This is obvious if you put your feet into Kim Jong-un’s shoes. Also they have many records of turning around. In order to read their minds, psychology and history are more important than following and analyzing their words or than depending on theory books. 相似文献

It is well recognized that glutamate is the major excitatory neurotransmitter, which is removed from the synaptic cleft by excitatory amino acid transporter 2 (EAAT2) located on the perisynaptic astrocytes and that neuronal death has been associated with an increased extracellular glutamate concentration. In this study, we have immunohistochemically demonstrated the expression of EAAT2 protein in the human brain after traumatic brain injury (TBI). The EAAT2 expression patterns can be divided into three types: continuous and highly extensive staining (E); continuous but sporadic staining (M); and sporadic pattern staining (S). In six of the nine short survival cases studied (1 h to 1 day), continuous and highly extensive staining for EAAT2 (E type) was observed in the ipsilateral cerebral cortex. On the other hand, we were able to demonstrate weak staining (S and M types) in 5 of the 7 long survival cases (> or =1 day) and in 12 of the 14 very short survival cases (<1 h) studied. Similar findings were obtained in the contralateral cerebral cortex and also in the ipsilateral hippocampus. In addition, positive staining for glial fibrillary acidic protein was detected around the cerebral contusion, but the EAAT2-positive expression was not observed in the same region for all of the six short and long survival cases (> or =1 h) after TBI. These findings clearly showed the differences in EAAT2 expression in the cerebral cortex according to the survival time and severity of cerebral contusion after TBI. Therefore, we emphasized that EAAT2 might play an important role in contributing to extracellular glutamate concentrations and secondary brain injury after TBI. 相似文献

Fluorescence differential display (FDD) and comparative RT-PCR have been used extensively to detect differentially expressed genes. We investigated hypoxia-induced gene expression in the brain by FDD-PCR and comparative RT-PCR. Mice were anaesthetized after which hypoxia was induced by neck ligation for 1 min or 25 min, then were killed by decapitation, and the brains were dissected either immediately or 30 min after death (Group A1-0, Group A25-0, Group A1-30 and Group A25-30). Control mice without ligation of the neck were killed by decapitation under anaesthesia immediately (Group C-0) or 30 min after death (Group C-30). FDD-PCR, sequence analysis and comparative RT-PCR revealed that mitochondrial thymidine kinase 2, Rab6, selenoprotein T and two novel cDNAs were enhanced in Group A25-0 and Group A25-30 compared with the other groups. In Group A25-30, only RAP2 interacting protein and another novel cDNA were induced. In Group A25-0, one novel gene was detected. These findings were consistent with the results of statistical analysis by ANOVA. No differences of band pattern were observed among Groups A1-0, A1-30, C-0 and C-30. The genes exhibiting altered expression were associated with vital cellular functions, e.g., intracellular signaling and mitochondrial metabolism. In addition, we identified four novel genes, expressed after extended hypoxic conditions in mouse brain with suffocation. These results may contribute to clarify the pathophysiology of asphyxia in the brain and aid in the diagnosis of suffocation. 相似文献

The objective of this paper is to elucidate the relationship between the reform process and economic performance in the states of the former Soviet Union (FSU). There were two strategies used by the former Soviet states to cope with the collapse of the USSR. Some of the FSU countries, in an effort to overcome the institutional vacuum caused by the disintegration of the federal economy, centralized their government authority to manage industry. Others decentralized power in an attempt to regain economic independence for domestic enterprises. To evaluate the essential differences and progress gaps among transition strategies, FSU countries can be divided into three groups, which reflect variations in institutional control of the government-business relationships. The differences in economic performance in FSU countries can be explained to some extent by examining the diversity of institutional patterns that characterize each category. The results of various empirical analyses positively support the validity of such an analytical framework. In this sense, this paper presents a new viewpoint on the transition process in FSU countries that may complement that shown in existing literature. 相似文献

The distribution of allele frequency of X-chromosomal STR, DXS10011, from 99 unrelated Japanese, 72 male and 27 female, were determined by PCR amplification and PAGE. At the same time, haplotype frequencies of five Y-chromosomal STR loci, DYS19, DYS389I, DYS389II, DYS390 and DYS393 from male samples were determined. 相似文献
