Helminthic infections lead to the release of various molecules which play an important role in modulation of the host immune system. Such filarial proteins with immunomodulatory potential can be used for therapeutic purpose in inflammatory and immune mediated diseases. In the present study, we have explored the prophylactic effect of filarial SXP–RAL family protein of Wuchereria bancrofti i.e. rWbL2 protein in DSS induced inflammatory ulcerative colitis in a mouse model. Prior treatment of rWbL2, followed by induction of colitis, showed significantly reduced disease severity as indicated by the decreased disease manifestations and improved macroscopic and microscopic inflammation. This preventive effect was found to be associated with increased release of anti-inflammatory cytokine IL-10 and decreased release of proinflammatory cytokines IFN-γ, TNF-α, IL-6 and IL-17 by the splenocytes of treated mice. From this study, it can be envisaged that pretreatment with filarial protein, rWbL2, can prevent the establishment of ulcerative colitis in BALB/c mice. The underlying immunological mechanism may involve the up-regulation of Th2 immune response with down-regulation of Th1 response.  相似文献

Matrix metalloproteinases (MMPs) play important role in the pathogenesis of coronary artery disease (CAD). 5A allele of -1612 5A/6A polymorphism of MMP-3 is associated with two fold higher activity than 6A allele. Present study was designed to analyse the association of this polymorphism with CAD in Indian population. Subjects included in the study were patients with stable angina (n=35), unstable angina (n=53), patients with recent event of myocardial infarction (MI) (MI Group-1, n=56) and patients at presentation of the acute MI (MI Group-2, n=49). Controls were healthy individuals (n=99). Genotyping of MMP-3 5A/6A polymorphism was carried out by PCR-based restriction digestion method. The genotype distribution of patient groups did not deviate from controls. Serum MMP-3 levels were significantly elevated at presentation of the acute MI by 36.8% (P=0.031) as compared to controls and more associated with 6A genotype suggesting discrepancy between in vitro transfection experiment and peripheral MMP-3 levels.  相似文献

There has been much debate concerning the pros and cons of special and mainstream education for young people with a disability. This paper adds data to this debate by reporting the educational experiences of 20 high-achievers with congenital disabilities who live in the United Kingdom and were born between 1950 and 1970. It presents personal accounts of the high-achievers' perceptions of how their education, which was either purely in special schools, in mainstream schools or a combination of both, had influenced their transition to adulthood. While those who attended special school considered it to provide a supportive environment that permitted the cultivation of their personalities without the constraints of non-disabled barriers, many others thought it prevented them as disabled children from interacting with non-disabled peers, thus inhibiting social integration between the disabled and non-disabled world. This was the main perceived advantage of mainstream education although problems of physical access meant that some choices were out of reach. The findings highlight how both special and mainstream education can be compatible with career success of individual disabled people. The paper implies that a combination of the two systems may be needed to facilitate disabled students to develop psychologically, socially and cognitively at the rate of their non-disabled peers, and proposes that link schools and partial integration could contribute to the achievement of such goals.  相似文献

ABSTRACT

In a networked society, humans are connected through mobile devices to always-on networks, and these technologies merge with us in new ways. In this environment, studying human-networked interactions involves an expanded type of usability. In this article, we argue that a key component of usability is how humans connect and disconnect from these networks. For this reason, the authors advocate studying how users connect and disconnect between online and offline contexts in their everyday life. Such an effort involves questioning our assumptions about the role of connection in usability and introduces methodological issues in studying these processes. These shifts require our research to be more multidisciplinary and more methodologically demanding, with major implications for the portability and durability of technical communication research.  相似文献

ABSTRACT

This paper explores the challenging situation faced by teachers as professionals and members of the community in Aceh, Indonesia during the province's civil war. It reveals how teachers’ sense of agency during this period was deeply influenced by the economic/material, political and socio-cultural condition at that time – conditions and experiences which today have bearing on a place for teachers in the post-conflict peace-building process occurring in the province. During the conflict, teachers struggled to balance their strategic societal positioning – as civil servants and community members – and found themselves caught in the middle of a complex range of hegemonic and counter-hegemonic forces at play. This position of constraint, we argue, limited the ability of teachers to act as peace-builders during the conflict, and continues to influence teachers’ ability to function in such ways today.  相似文献

This article examines how non-governmental organizations create resources and spaces for girls and women’s education and empowerment in China, India and Pakistan – in the context of global expectations and local state relations as well as cultural norms. We examine the dynamics that foster female empowerment associated with educational attainment. Analysis showed that the five NGO’s responses to enabling and constraining local needs and demands gave rise to productive friction that activated positive development. We conclude that engaging local individuals as managers, teachers or facilitators who can negotiate with international actors and with the state is an effective foundation for maintaining a balance between being accountable to local contingencies and norms and to global social justice principles of the projects. These models indicated that “effective scale” might better be defined as a collaboration between the local and global, rather than “scaling up” in size.

International NGO partnerships with several of state organizations and local leadership can be a catalyst for fundamental change, subject to dynamic engagement with productive friction that activates educational empowerment and social change.  相似文献
