Bacterial infection due to Bartonella henselae commonly develops in children and young adults following cat/dog contacts and/or cat/dog scratches. Regional lymphadenopathy is its most common clinical expression. However, encephalitis and Parinaud's syndrome (oculoglandular syndrome) have also been reported as has systemic illness. A review of the international literature in all languages revealed no fatal complications in immunocompetent hosts. A four-year-old white child with no underlying illness began to have seizure-like activity. She was taken to a local hospital and subsequently transferred to a medical center. The child was treated aggressively for seizures and fever of unknown origin. However, her condition rapidly declined and she died without a specific diagnosis. At autopsy there was marked cerebral edema with no gross evidence of acute meningitis. Microscopic exams revealed multiple granulomatous lesions as well as a meningitis and encephalitis. A variety of cultures and stains were negative for acid fast and fungal organisms. Warthin-Starry stains of involved tissue including brain and liver revealed pleomorphic rod shaped bacilli consistent with Barronella henselae. Analysis of brain tissue with polymerase chain reaction (PCR) and Southern blot for the deoxyribonucleic acid (DNA) was definitive for DNA of Bartonella henselae bacteria.  相似文献

But under the requirement of philosophic consistency, and the impact of the perfectly valid reflection that experience is always my experience, and never part of some object independent of me, the world shrinks to the extension of my experience only, and I am left with bundles of my sensations. What are the natural consequences of such an epistemological sophistication? One plausible and natural reaction is what one might call the ‘Indian’ one. It runs roughly as follows: my experience of the world is, alas, only my experience. It is not ‘the real’. Moreover, the world disclosed in my experience is one of misery, precariousness, insecurity, which ends in old age and death and within which no secure, reliable, undeceptive goods can be found. The flux and precariousness which make it so unhappy a place, also make it most ill-suited to be an object of knowledge. — E. Gellner (1974: 114)  相似文献

Abstract: Canine biological specimens are often part of the physical evidence from crime scenes. Until now, there have been no validated canine‐specific forensic reagent kits available. A multiplex genotyping system, comprising 18 short tandem repeats (STRs) and a sex‐linked zinc finger locus for gender determination, was developed for generating population genetic data assessing the weight of canine forensic DNA profiles. Allele frequencies were estimated for 236 pedigreed and 431 mixed breed dogs residing in the U.S. Average random match probability is 1 in 2 × 1033 using the regional database and 1 in 4 × 1039 using the breed dataset. Each pedigreed population was genetically distinct and could be differentiated from the mixed breed dog population but genetic variation was not significantly correlated with geographic transition. Results herein support the use of the allele frequency data with the canine STR multiplex for conveying the significance of identity testing for forensic casework, parentage testing, and breed assignments.  相似文献

This article examines the Advocate-General's comments on the ‘hosting’ provision in the eCommerce Directive (00/31/EC). He suggests the existence of a ‘neutrality’ principle in respect of intermediary liability, which operates irrespective of an intermediary's knowledge about the legality or otherwise of the hosted content. This article critically examines this suggestion within the broader debate about the role and responsibilities of intermediaries in a cyberspace context.  相似文献

Abstract

Contemporary shifts in scholarship and institutional agendas, I argue, have created new sets of challenges for feminist history. While these do not undermine the paradigms of this scholarly endeavour, there has been an inevitable shift in how feminist history is now written, conceptualised and undertaken. A hallmark of dynamic and innovative scholarship is a capacity to evolve and respond to intellectual challenges and developments. There is much to be positive about in the future, as I believe feminist history at its best has not remained a passive or static body of knowledge, but continues to be reformulated and reconceptualised, but with this dynamism comes uncertainties which institutional change can bring. While I do not believe these are systemic enough to pose a challenge to the enterprise, I suggest they do create cause for wider discussion, especially about the place of the humanities more generally in the corporate university of the twenty-first century.  相似文献

A wide array of institutions governing climate change has proliferated over the past years, influencing the rule-makings of the regime. One of them is the G20. When G20 leaders around the world convened in London to restore global economies, they stressed the importance of a ‘resilient, sustainable, and green recovery’ and reaffirmed their commitments to address climate change. This was followed by their agreement on phasing out inefficient fossil fuel energy subsidies over the medium term in Pittsburgh. The ‘coexistence of narrow regimes in the same issue-area’ could be described as ‘regime complexes’, which enable countries to adapt more readily, particularly when adaptation requires complex changes in norms and behavior. Given that responses to climate change would require changes in the domestic politics of different countries at different levels, loosely integrated institutions of regime complexes could be more advantageous for countries to adapt and in engaging with developing countries. This paper demonstrates that the G20’s highly informal institutional setup as well as its flexible cooperation tools could enable its members to customize their policies and better engage with third-party countries. In addition, the G20 group could collectively influence other key countries to reach an agreement on some of the key climate change–related issues, thereby facilitating the United Nations process of climate change.  相似文献
