In 7 of 15 cases of sudden infant death syndrome (SIDS), distinct periventricular fatty metamorphosis of the neuroglia could be demonstrated by a histological staining technique. None of the six children (under 1 year of age) used as a control group whose cause of death was not SIDS showed this morphological change. Thin-layer chromatographic analysis of the lipids accumulated in the glial cells in SIDS established a high amount of esterified cholesterol whereas the content of esterified cholesterol in the control group was low. We presume that fatty metamorphosis of the neuroglia represents the morphological substrate of a metabolic disorder of the sensitive, immature glia of the periventricular white cerebral matter caused by various kinds of damage.  相似文献

The main objective of this paper is to examine the evolution of European Union (EU) climate strategy, scrutinising in particular developments in EU's views on the so-called flexibility or Kyoto mechanisms. In brief, the paper argues that there has been a gradual change in EU's views, from the role of a sceptic in the run-up to Kyoto towards becoming more of a frontrunner on emissions trading in recent years. The need to 'save Kyoto' and the protracted development of EU climate policy are highlighted as two of the most important drivers behind this process of change. This paper also discusses some of the lessons learned from international negotiations and the development of EU climate policy. Finally, and drawing upon the lessons learned, the paper explores key future challenges for the further development of EU climate strategy.  相似文献

Childhood sexual abuse has been associated with HIV transmission risk behavior in men who have sex with men. This study examined an adapted model that was originally developed to explain the relationship between childhood sexual abuse and HIV risk behavior among women in a sample of men who have sex with men. Men attending a large gay pride event (n=647) completed anonymous surveys that assessed demographic characteristics, childhood sexual abuse, symptoms of dissociation, trauma-related anxiety, borderline personality characteristics, hopelessness, substance use, and sexual risk behavior. A latent variable partial least squares analysis was conducted to test the interrelationships between childhood sexual abuse, exchanging sex for money or drugs, emotional disturbances, drug use, substance use in the context of sexual behavior, and sexual risk behavior. The model fit the data well and accounted for 10% of the total variance in sexual risk behavior. History of childhood sexual abuse predicted exchanging sex for money or drugs and this relationship was partly accounted for by active drug use. Substance use proximal to sexual behavior also emerged as a key factor in predicting sexual risk behavior. Findings from this study, therefore, indicate a direct association between history of child sexual abuse and high risk for HIV infection related to engaging in sex trade.  相似文献

The authors previously explored invention licensing from the university's perspective. In this paper we focus on the process from the perspective of firms activity engaged in licensing technology. A survey of industry licensing professionals addresses why some firms license technologies from universities and why others do not. The paper then considers the stage of development of university technologies, the characteristics of their licensing contracts, and sources of information about university technologies, all to better understand how the process works and what advantages and disadvantages it offers to all participants.  相似文献

The authors introduce a group of essays that evolved from a March 2003 symposium on the path-breaking new partnership and use of interest-based negotiation (IBN) at Kaiser Permanente (KP), one of the largest integrated health care programs in the United States. They briefly trace the history of the IBN approach (both success stories and failures); the growth of this phenomenon; and its use in collective bargaining settings. The KP case, the focus of the symposium (which was jointly sponsored by MIT's Institute for Work and Employment Relations and Harvard's Program on Negotiation), is by far the largest instance of the use of IBN in U.S. labor relations history.  相似文献
