大肠埃希氏菌F18菌毛结构蛋白与黏附特性的关系

利用已表达的F18ab和F18ac菌毛各结构亚单位的融合蛋白(GST-FedA/ab、GST-Fe-dA/ac、GST-FedE、GST-FedF/ab、GST-FedF/ac)分组肌肉注射健康家兔,制备抗FedA/ab、Fe-dA/ac、FedE、FedF/ab、FedF/ac多价血清。结果表明,所制备的5种抗Fed多价血清均能凝集F18ab 大肠埃希氏菌107/86株和F18ac 大肠埃希氏菌8813株。利用抗大肠埃希氏菌F18菌毛主要结构亚单位FedA特异抗体和次要结构亚单位FedE、FedF特异抗体,研究了F18菌毛与小肠上皮细胞的黏附特性。结果发现,FedA抗体和FedE抗体单独和合并均不能抑制F18 菌与小肠上皮细胞的黏附,而单用抗FedF抗体即能明显抑制F18 大肠埃希氏菌与小肠上皮细胞的黏附,表明FedA和FedE与F18菌毛的黏附不具相关性,而FedF才是F18菌毛的黏附性结构亚单位。     

支撑现代政治正义制度的美德精神——西方现代政治伦理论争

西方现代政治伦理论争揭示:现代政治正义制度无法脱离公民美德精神而独立存在,必须获得公民美德精神的支撑.不同思想家关于现代政治制度正义与个体美德关系的论辩分歧,事实上均以自己的特殊方式提出了统一二者的渴望,这表明二者是互为依赖、互为因果、双向互动的互反馈平衡系统.     

Cerebral massive hemorrhage in congophilic angiopathy and its medicolegal significance

The principles of a special type of senile cerebromeningeal angiopathy, these days usually named “congophilic angiopathy”, are demonstrated on the basis of eight cases, complicated by spontaneous massive intracranial hemorrhages in seven and late traumatic hemorrhage in one of them. The occurrence of massive hemorrhages associated with congophilic angiopathy has until now only rarely been reported. The medicolegal significance of this vascular disease is emphasized by the eighth, traumatic, case, which became forensically relevant; the late massive hemorrhage had to be regarded as significantly favoured by amyloid angionecrosis, which is the main feature of congophilic angiopathy.     

Detection of genotype recycling fraud in U.S. immigrants

Abstract: Relationship testing laboratories provide genetic evidence to support or refute claims of kinship between U.S. citizen petitioners and potential immigrant beneficiaries. One female beneficiary presented a male amelogenin type and alleles at 15 autosomal loci that were identical to an alleged brother’s. Laboratory records showed that her alleged father had petitioned to have 15 children emigrate from Ghana. The petitioner’s 15 paternity indices exceeded 10⁵, but the children shared only four short tandem repeat (STR) profiles, suggesting fraudulent reuse of genotypes in this alleged pedigree (AP). To determine the extent of this “genotype recycling,” I examined the laboratory’s 555 APs from Ghana and 532 control APs from Nigeria. Seventeen Ghanaian APs (3.1%) but no Nigerian APs showed genotype recycling. Of 90 tested people in the 17 APs, 56 shared identical STR profiles with others in their AP. Of these 56 people, 10 were petitioners with unexpectedly high parentage indices. Seven of 56 had amelogenin types that disagreed with their declared genders. Database searches for identical multilocus genotypes in allegedly different people would best detect this fraud.     

Towards a neo-Polanyian approach to money: integrating the concept of debt

Abstract

This paper aims to reconsider Polanyi's approach to money. His best-known writing on money uses is deeply original and presents strong insights that dissociate money from the concept of the market. Polanyi also developed an interesting non-dichotomous understanding of money in his The great transformation. However, taken together, these two contributions lead to some unresolved questions: his critique of the orthodox approach to money is ambivalent; his argument to separate payment from account is weak; and, most important, he ultimately makes an incomplete break with the classical real/monetary dichotomy. This paper proposes a distinction between money as a set of instruments and practices and money as a concept, through the integration of John Commons's concept of debt into Polanyi's framework. This reformulation allows us to resolve Polanyi's unresolved questions while preserving his major contributions, and leads to a more complex understanding of money.     

Paradigms in South African cinema research: Modernity,the New Africa Movement and beyond

Abstract

The history of theoretical approaches about South African cinema is discussed from the turn of the twentieth century period of the New Africa Movement, through various other theoretical moments, up to the early 1990s. These include conservative cultural theory, liberal humanism, workerist, Althusserian and Gramscian Marxisms. The discussion examines theoretical interventions either promoting or opposing modernity in the work of Thelma Gutsche, Hans Rompel, John Grierson and various Afrikaner cultural organisations during the first half of the twentieth century. Post-1970s cinema theory is critically examined in relation to discursive contestation occurring within both academia and the industry.     

Warburg’s “Goddess in Exile”

Abstract

As regards Aby Warburg’s oeuvre, it is fascinating that three unfinished or unpublished projects have come to represent the very theorems now appearing of most interest for cultural historians and theorists: The Mnemosyne Atlas representing pictorial memory; the Serpent Ritual as theorem for a cultural-anthropological reading of pagan cultures; and the Nymph Fragment as a foundational figure of modern iconology. This essay undertakes an analysis of the fragmentary character of Warburg’s way of working, arguing that his search for an analytic model to account for the interplay between Christian and pagan/polytheistic traditions displays striking asynchronies and displacements. Rather than explicating these irregularities biographically, the conceptual problems tied to his methods and cognitive interests are investigated. The article thus examines a set of conceptual questions whose relevance extends well past Warburg’s methodology, considering the dimensions of religious and cultural-historical theory within a broader history of European arts and media. Concentrating on probably the most cited figure from Warburg’s repertoire of images, the “nymph” figure on Ghirlandaio’s fresco The Birth of St John the Baptist, the essay focuses on Warburg’s borrowings from Heinrich Heine and reveals Heine to be a blind spot in research on Warburg up until now.
