Hepatodiaphragmatic interposition of the colon is a rare, usually asymptomatic, anomaly and is typically an incidental radiologic finding. There are few cases in the literature describing the symptomatic form of the condition, known as Chilaiditi syndrome. In some cases, it may be accompanied by various severe complications. If symptoms are present, usually conservative treatment is given. However, conservative treatment only addresses the symptoms but does not prevent their recurrence and possible complications. Our present report shows that this anomaly may not only cause symptoms, but may also progress and cause severe complications, in our case—megacolon leading to right heart failure and, ultimately, death. To date, however, there have been no literature reports of death caused by colonic interposition. Therefore, it is important to draw attention to the importance of this anomaly and its appropriate diagnosis and treatment to ensure the most favorable patient outcomes. 相似文献

This study investigates the effectiveness of collaborative governance in the context of state and local government responses to the COVID-19 pandemic in Florida. Our analysis uncovers how local authorities have successfully adapted to implement policies to increase resilience and address the crisis, despite facing challenges, constraints, and limitations. Our findings underscore the significance of considering unique local characteristics when addressing pandemics and shed light on the potential influences of state-level actors on Home Rule. Notably, research examining the interplay between state decisions and Home Rule during a pandemic is scarce. We utilize Florida as a case study to examine local government responses to COVID-19, employing a qualitative analysis of data from webinars hosted by the Florida League of Cities and media reports on local government actions. To substantiate our findings and encourage further research, we apply the collaborative governance framework in the context of local government administrative responsibilities. 相似文献

猪生殖与呼吸综合征病毒△Gp5/M/N串联基因的克隆及原核表达 总被引:2,自引:0,他引:2
采用RT-PCR方法从猪生殖与呼吸综合征病毒(PRRSV)美洲株VR2332中扩增△Gp5、M和N基因片段,通过重组PCR方法得到串联基因△Gp5/M/N,将其克隆到原核表达载体pET-30a(+)上,并转化大肠杆菌感受态细胞BL21(DE3)pLysS,筛选表达PRRSV pET-△Gp5/M/N蛋白的菌株.经IPTG诱导表达,进行SDS-PAGE分析和western-blotting.结果表明,PRRSV pET-△Gp5/M/N蛋白在大肠杆菌中以包涵体的形式表达,纯化后的蛋白可与PRRSV阳性血清发生特异性反应.证明原核表达系统表达的PRRSV pET-AGp5/M/N蛋白具有良好的反应原性. 相似文献

Despite recent changes in international relations and lapse of time since the fall of the USSR, the issue of Russian membership in NATO has been an ongoing fact. Hence, the principle scope of the paper is SWOT analysis of potential Russian membership in NATO from the perspective of the Russian Federation. Through the introduction and evaluation of advantages and disadvantages of such membership in the light of latest geopolitical events in Eurasia suggested by academic and professional circles in NATO countries and Russia, we proceed with identification of fundamental strengths, weaknesses, opportunities and threats that Russia might face. Taking into account such determining factors as the size of its territory, shifting geopolitical conditions in the world, modern understanding of security and a potentially frozen dispute in Ukraine, we come to the conclusion that benefits potentially brought by Russian membership in NATO could be sustained while drawbacks could be eliminated by incorporation of NATO to OSCE and a change in voting procedures of the Alliance. 相似文献

Over the past 15 years there has been an increase in the use of local direct democracy in the Czech Republic. The analysis shows that the primary cause has been the regulation of development projects. Using transaction costs economics (TCE) approach it is shown how the regulation related to the siting of development projects leads to a not-in-my-backyard (NIMBY) response resulting in political activism that uses institutions of local direct democracy. Drawing from the TCE perspective, in this article it is argued that the key sources of this political mobilisation have been the existence of contractual hazards related to development projects and an inability to form credible commitments between developers and communities. The article highlights a previously neglected explanation for the increased use of direct democracy because sources outside the political system often go unnoticed and contributes to the research on NIMBY disputes and on the expansion of direct democracy. 相似文献

The article focuses on the attitudes of two militant Islamist groups, Al Qaeda and the Islamic State, toward the issue of terrorist attacks in the energy sector. The main aim of the article is both to analyze the importance of attacks on energy infrastructure for the strategies of these two organizations, and to describe specific examples and manifestations of terrorist activities from the side of Al Qaeda and the Islamic State with regard to the energy sector in the Middle East and North Africa. The article is based on the concept of terrorist attacks on the energy sector. 相似文献

Part of the literature views high numbers of presidential candidates as a threat to political stability in presidential democracies. A contradictory model proposes that an overconcentration of the presidential party system is problematic. Both models are hard to reconcile. We approach this puzzle by arguing that the relationship between the level of presidential election fragmentation and governability crises is curvilinear: both very low and very high effective numbers of presidential candidates increase the risk of governability crisis. We test this theoretical claim with ordered logit models drawing on a sample of 108 presidencies in Latin America between 1978 and 2013 and using an ordinal index of the intensity of crisis as the dependent variable. We explore the operation of the theorized causal mechanisms through case studies and argue that they are different at both extremes, high and low levels of fragmentation. Finally, we formulate implications for the design of presidential electoral rules drawing on the debate contrasting runoff and plurality rules. 相似文献

Emotional separation and parental trust in parent–adolescent relationships are important factors for adolescent identity formation. However, prior research findings on emotional separation are inconsistent. This study aimed to conduct a more rigorous examination of the associations of emotional separation and parental trust with identity synthesis, confusion, and consolidation by applying a bi-factor model to identity, using adolescent samples from Lithuania (N?=?610; 53.9% female; M age ?=?14.92), Italy (N?=?411; 57.4% female; M age ?=?15.03), and Japan (N?=?759; 43.7% female; M age ?=?14.13). Structural equation modeling revealed that emotional separation and parental trust were consistently associated with identity consolidation across the three countries, rather than associated with identity synthesis and identity confusion. Furthermore, the patterns of associations of emotional separation and parental trust with identity synthesis and identity confusion differed across the three nations. Overall, this study provides a better understanding of the role of emotional separation and parental trust in adolescent identity formation by suggesting the importance of the identity consolidation in the association between parent–child relationships and identity formation across three countries. 相似文献
