Chronic oral anticoagulant treatment is obligatory in patients (class I) with mechanical heart valves and in patients with atrial fibrillation with CHADS2 score >1. When these patients undergo percutaneous coronary intervention with placement of a stent, there is also an indication for treatment with aspirin and clopidogrel. Unfortunately, triple therapy is known to increase the bleeding risk. For this group of patients, the bottom line is to find the ideal therapy in patients with indications for both chronic anticoagulation therapy and percutaneous intervention to prevent thromboembolic complications such as stent thrombosis without increasing the risk of bleeding.

The objective of this paper is the structural and narrative reconstruction of representations of ‘nature’, ‘wildlife’ and
‘landscape’, held by rural residents of the Dadia Forest Reserve. Data collection involved in-depth interviews. Employing
a social representations’ approach, we recovered representational elements that are expected in the case of rural belief systems,
such as negative dispositions towards wolves and foxes, as well as elements of an urban adherence, such as nature’s independence.
Representational elements refer to visual aspects of the countryside, which seem compatible with the figurative nucleus of
the rural idyll. Concerning ‘wildlife’, residents focused on vultures, which comprise the main tourist attraction of the reserve.
Scientific knowledge adds to the complexity of the narrative schema, which corresponds to the representation of ‘wildlife’.
Interviewees perceived the rural landscape as an interface between the natural and the human-conditioned environment. Our
study shows that interviewees make no reference to environmental conservation or quality of life issues, as it could be expected
according to relatively wide definitions of the term ‘environmentalism’. Environmental messages reinforced by ecotourism development
seem to be recalled primarily in terms of their compatibility with the perceived economic benefit of local people. Despite
ecotourism development, representational elements that diverge from a tourist version of ‘nature’, ‘wildlife’ and ‘landscape’
were not pronounced within rural belief-systems. Further interventions within the study area are needed, in order to address
a variety of topics under the environmental conservation discourse and raise the environmental awareness of rural residents. 相似文献

In this short response to Loïc Wacquant's ‘Marginality, Ethnicity and Penality in the Neo-liberal City’, I outline two intellectual conversations that emerge from the author's work. The first develops out of the connections that the author draws between systems of criminal justice and welfare. The second grows out of the disassociation he urges us to see between the logics and trajectories of crime, on the one hand, and criminal justice on the other. I then briefly describe how my own work has been influenced by and contributes to these two ongoing streams of research. 相似文献

Summary The nature of the steroids secreted by gonads of fish differs significantly from those of the mammals. The classical teleost steroids, oestradiol, testosterone, 11-ketotestosterone and 17,20P, have been measured in a wide variety of teleosts but do not always reflect biological activities. There is increasing evidence that teleost gonads may produce a number of non-classical steroids which may play an important role in their reproductive biology. Such products include metabolites reduced at C5 to 5 or 5, at C3 to 3 or 3, or hydroxylated at 6-, 7-, or 21. Conjugation, as either glucuronides or sulphates, may contribute either to localization of action within the gonad or to production of pheromones during the immediate pre-spawning period. Although it is often possible only to measure the steroids for which assays are readily available, it is important to recognize that there may be production of steroids that are not detected by such assays, but which nevertheless play a major role in reproductive activity. In evolutionary terms, the teleost hydroxylases probably originated in the very early fishes and show parallels with their analogues in amphibians and mammals. Gene sequencing may reveal a possible common ancestor for all vertebrate 6, 7 and 11-hydroxylases. 相似文献

Perchloroethylene (PCE) was tested in a diploid strain (D7) of the yeast Saccharomyces cerevisiae in suspension tests with and without a mammalian microsomal activation system (S9) and ‘in vivo’ by the intrasanguineous host-mediated assay. In addition, enzyme alteration studies were performed in mice non-pretreated or pretreated with phenobarbital + β-naphthoflavone. PCE did not induce any genetic effect either ‘in vitro’ or ‘in vivo’. In the suspension test, PCE was more toxic without metabolic activation and less toxic with mammalian microsomal activation. The enzymatic determinations showed an increase of the aminopyrine demethylase activity and of the level of cytochrome P-450. 相似文献

While ‘ethnicity and everyday life’ is a familiar collocation, sociologists concerned with racism and ethnicity have not engaged very much with the extensive body of social theory that takes the ‘everyday’ as its central problematic. In this essay, I consider some of the ways in which the sociology of the everyday might be of use to those concerned with investigating ethnicity and racism. For its part, however, the sociology of the everyday has tended to be remarkably blind to the role played by racism and racialization in the modern world. It is thus no less crucial to consider how the experiences of racialized groups might help us rethink influential accounts of the everyday. To this end, I provide a discussion of pioneering texts by C. L. R. James and W. E. B. du Bois, both of whom were driven by their reflections on racism and resistance to recognize the everyday not as an unremarked context, but as, precisely, a problematic one. 相似文献

In India, touch is a prime marker of status and social relations. Those who are impure are ‘untouchable’,1 but those who are of a relatively higher purity are also, depending on the context, either ‘untouchable’ or ‘touchable’ only under certain fixed rules. In this paper, I will explore the contexts in which body contact and touch can be part of personal relations. I describe how these body contacts signify important social relations and establish community identity. Further, I will analyse how patterns of body contact on the one hand change during childhood, and on the other hand produce changes in the status of a social persona. The last point to be investigated is the meaning of touch as a sign for public representations. 相似文献

The decomposition of two macroalgal species Cladophora glomerata (CHLOROPHYTA) and Pilayella littoralis (PHAEOPHYTA) was studied in the laboratory and field conditions. These species are known to cause the extensive macroalgal blooms in the whole coastal range of the Baltic Sea. The objective of the experiments was to determine decomposition rates of the macroalgae, follow the changes in tissue nutrient content and validate the role of benthic invertebrates in this process. In the laboratory conditions, the differences in the decomposition rates of the algae were mainly due to the oxygen conditions. The weight loss of C. glomerata was slightly higher in anaerobic conditions than in aerobic conditions. If 99% of initial dry weight of P. littoralis was lost in aerobic conditions then only 20% was lost in anaerobic conditions. In general, the loss of phosphorus and nitrogen in algal tissues followed the weight loss. As an exception, the amount of nitrogen changed very little during the decomposition of C. glomerata. In field conditions, the photosynthetic activity exceeded the decomposition rate of C. glomerata at lower temperatures in spring. The decomposition of P. littoralis was estimated at 49% of its initial dry weight. The addition of benthic invertebrates had no effect on the decomposition process. In summer, the decomposition rates were estimated at 65% for C. glomerata and 68% for P. littoralis being in the same order of magnitude as observed in laboratory conditions. If the decomposition of C. glomerata was faster at the end of the experiment, the most significant losses of weight of P. littoralis took place during the first 2 weeks of deployment. Idotea baltica significantly contributed to the loss of C. glomerata. The decomposition rate of P. littoralis was reduced by the presence of Mytilus edulis and increased by Gammarus oceanicus. 相似文献

Contesting the ‘model minority’: racialization,youth culture and ‘British Chinese’/‘Oriental’ nights
Diana Yeh 《Ethnic and racial studies》2014,37(7):1197-1210
While racialized youth are often central in debates on citizenship, multiculturalism and belonging, those ascribed as ‘British Chinese’ are constructed as model minorities, lacking a hybridized culture but insulated from racism, and thus invisible in these discussions. This article argues, however, that the model minority discourse is itself a specific form of contemporary racialization that revives ‘yellow peril’ discourses on the capacities of particular ‘Oriental’ bodies. Drawing on ethnographic fieldwork, it examines how young people challenge these constructions, by drawing on popular culture to organize and participate in what they call ‘British Chinese’ and, more provocatively, ‘Oriental’ nightlife spaces. It analyses how through these spaces participants forge a sense of identity that allows them to reimagine themselves as racialized subjects. It demonstrates how these spaces constitute transient sites of experimental belonging, facilitating new cultural politics and social identifications that at once contest reified conceptions of British Chineseness yet also create new exclusions. 相似文献

The distribution of Alu-family DNA repeats (AFRs) in chromosomes of phytohaemagglutinin-stimulated peripheral blood lymphocytes of four normal donors and non-stimulated bone marrow cells of four patients with acute leukemia (ALL and ANLL) was studied by in situ hybridization using DNA of recombinant phage lambda containing multiple inserts of AFR as a probe. Over some chromosome bands (14cen, 16p13, 16cen) from normal donors and from leukemic patients clusters of silver grains were detected. Over other three bands (3q26, 8p11-p12 and 14q24) the clusters were found only in chromosomes from the four acute leukemia patients, and were absent from chromosomes of healthy donors. The results suggest non-random long-range distribution of AFRs in human chromosomes, and somatic variations in the distribution of the repeats. 相似文献

A ‘new Irish’ American ethnicity surfaced in the 1980s – according to a number of scholars and journalists – and is comprised of what some consider to be more ‘authentic’ and ‘traditional’ Irish cultural attributes. Defining authentic and traditional Irishness is complicated, however, by the recent influx and highly visible forms of economic capital and media attention stemming from the Celtic Tiger – the surge of economic prosperity that began in Ireland in the 1990s – and the commercializing of Irish music and dance – such as Riverdance. In this paper, I propose, through my study involving Irish language enthusiasts, that this ‘new’ form of Irish ethnicity is more the result of rather than the reason for this surge in popularity. I use Pierre Bourdieu's ‘Forms of Capital’ in questioning the ‘new Irish’ American ethnicity, arguing instead that a deeply seated, less-visible reservoir of cultural and social capital form the basis for this perceived contemporary ethnicity. 相似文献

Self‐reported incidence of racial discrimination was investigated among four Asian‐American groups to explore their magnitude and the ways of coping with the discrimination episodes. The samples showed that among the two modes of coping ‐ problem‐focused or emotion‐focused coping ‐ a majority of Asian Americans has utilized the latter. Reasons of adopting these coping strategies were further explored for their determinants. Intergroup differences in ethnicity, education, gender and cultural values were found to exert influences on the ways of coping with racial discrimination among Asian Americans. 相似文献

Analyses of multicultural state-dictated social categories are often governed by those same categories, even while they deconstruct them. Nonetheless, these categories are often used in public spheres such as national imaginary or ethno-political activism. Taking a different point of departure, that of representations rather than the categories themselves, the aim of our paper is to understand the modes of classification that are relevant among four populations in Colombia and Mexico who would, a priori, be categorized as ‘black’ or ‘Indian’. The daily reality of these groups indicates other possible internal, sometimes even intersecting, kinds of categorizations, which, far from naturalizing the ‘Indian’ and ‘black’ categories, in fact reveal place-based social identifications. These identifications seem closer to the everyday lives and practices of the people in question, and underscore the local conceptions of their presence and agency in a given spot. 相似文献

This review explores Rex and Moore's (1967) study of Birmingham as an enduring model of ethnic segregation, stratification, conflict and cooperation. The commentary focuses on the legacy of this research for understanding ethnic segregation, community and the city as a barometer of social change. 相似文献
