The dog’s precordial region at the sternum was impacted with a mechanical elastic-cord propelled impactor at the velocity of 8.0 m/s. The left and right intraventricular pressures and electrocardiogram (ECG) were monitored continuously for 60 min after the impact. The micro- and ultra-structure of myocardium were examined. Localization of myocardial myoglobin (Mb), creatine kinase BB (CK-BB) and creatine kinase MM (CK-MM) as well as plasma membrane permeability were studied by immunohistochemical and lanthanum probe techniques. Upon the impact, abrupt over-pressures within both ventricles were recorded with transient depression of the left ventricular systolic pressure. In all the dogs, some rhythm- and conduction-disorders were noted, which lasted transiently and resumed to normal sinus rhythm. At autopsy, no gross injuries of the heart were detected, and microscopic examination showed no visible myocardial lesions. However, immunohistochemically, focal patchy loss of myocardial Mb, CK-BB and CK-MM was identified with scattered deposition of these substances between myocardial fibers elsewhere. Such changes as relaxed myofibrils with widened I band, contracted myofibrils and broken cristae of the mitochondria were observed in myocardial ultrastructure. Lanthanum particles deposited inside the mitochondria. These results indicate that increase in cardiac cell membrane permeability and ultrastructural damage in myocardium may be involved even in cardiac concussion.  相似文献

The use in forensic medicine of methods pertaining to molecular biology has made it possible to identify human remains through the analysis of polymorphic profiles of human DNA. Voluntary, accidental, or natural postmortem degradation, as well as environmental conditions, influences the preservation state of the corpse, making it sometimes difficult to obtain biologic material suitable for genetic analysis (e.g., hair, soft and/or hard tissue). According to their anatomic/morphologic characteristics, dental formations are particularly resistant to external insults and are thus suitable for this kind of research. The purpose of this work, conducted on nonselected dental findings (presenting intrinsic characteristics similar to those usually found in forensic cases) that were homogeneous with regard to environmental factors, was to determine an operative protocol that will enable combination of the maximum availability of genomic DNA with the preservation of the morphologic characteristics of the tooth for classic anthropologic evaluations.  相似文献

重修丝绸之路:迈向亚洲一体化   总被引:2,自引:0,他引:2  
丝绸之路是指将东亚、中亚、南亚与地中海沿岸国家(包括北非和欧洲)连接在一起的、纵横交错的泛亚贸易交通网络。在过去的几十年中,随着全球化的不断深入,亚洲再度成为世界经济的重心。许多亚洲经济体成为了国际生产网络中不可分割的一部分,他们自身也从不断扩大的国际贸易、投资以及加速的经济增长中获益良多。然而,由于缺乏区域性连接,亚洲巨大的发展潜力尚未发挥出来。本文认为,缺乏全面的区域性连接是影响地区增长、阻碍亚洲乃至世界一体化进程的重要因素之一。鉴于此,亚洲应该加强地区通道建设,使之成为国际通道的一部分。本文还讨论了在通过泛亚运输基础设施建设实现地区连接的过程中,可能遇到的一系列问题和挑战。  相似文献

This paper reviews the literature on the communication policy of the European Central Bank (ECB) addressing two questions. First, to what extent has ECB communication affected interest rates? Second, to what extent has ECB communication affected the predictability of the ECB’s interest rate decisions? On the basis of a survey of empirical studies, it is concluded that various forms of ECB communication lead to more volatility. However, studies focusing on volatility cannot assess whether markets moved in the intended direction. To analyze whether this is the case, researchers have coded ECB communications. Studies using this approach yield evidence that communications generally move financial markets in the intended direction. There is also substantive evidence that ECB communications increase the predictability of interest decisions by the ECB Governing Council. Finally, the consequences of the fact that ECB officials often gave contrasting signals to market participants are analyzed. New evidence suggests that inconsistent communication causes agents to make less accurate predictions. The policy implication is that central bankers should take care that their statements are consistent.  相似文献

Post-mortem diagnosis of chronic alcohol abuse is a challenge for forensic experts due to the lack of pathognomonic morphological findings and often also inadequate background information. Objective methods demonstrating chronic excessive alcohol consumption would therefore be a useful tool for forensic pathologists. In clinical practice, several markers of chronic alcohol abuse have recently been introduced, among which carbohydrate-deficient transferrin (CDT) is the most accepted, but the use of these markers in autopsy has not yet been established. We examined post-mortem stability and possible post-mortem redistribution of CDT and compared two analytical methods, capillary zone electrophoresis and high-performance liquid chromatography. According to our results, CDT remains stable for an appreciable time after death. The results further indicate that CDT is not subject to major post-mortem redistribution.  相似文献
