The year 2015 throughout Russia was much less about what it seemed than what it revealed. On the surface, after the September 2015 combined regional and local elections, Russia appeared to be tranquil, politically disengaged, and supportive of President Vladimir Putin. The underlying reality was quite different. The election exposed a country divided by rivalry and a conflict of interests within the Russian political establishment set off by Putin’s own policies over the preceding two years. Since the election, Putin and the Kremlin have been confronting the challenge of balancing and containing the competing interests of institutions, levels of government, and establishment stakeholders who are less easily reconciled or controlled. 相似文献

Pulmonary embolization of cerebral tissue as the result of severe head trauma is an uncommon, if not rare, phenomenon, and few cases have been reported in the literature. The authors discuss the case of a 51-year-old male who died six days after suffering extensive head trauma in a motor vehicle collision. At autopsy, white-gray emboli were found in several subsegmental pulmonary arteries. The results of histologic examination with the hematoxylineosin stain gave the impression that the emboli were necrotic cerebral tissue; however, routine special stains for neural tissue produced inconclusive results. Immunohistochemical staining of the emboli with monoclonal mouse anti-human neurofilament protein (Dako Corp., Carpinteria, California) confirmed the cerebral nature of the emboli. To the authors' knowledge, this is the first reported case of pulmonary embolization of cerebral tissue confirmed by immunohistochemistry. 相似文献

The impact of a court service that is set up to enforce access orders is measured from the perspective of 70 children whose parents were program participants in the service. Children's perception of conflict diminished significantly over the 6-month period of service involvement. Children improved in their overall and school adjustment when visits with their noncustodial parents were more frequent. They were less depressed when they had quality relationships with both their mother and father. Children perceived more conflict as visits increased, but the negative impact was minimal. 相似文献
