Fungi are non-chlorophyllus microorganisms, which constitutes the main source of outdoor and indoor allergens. The antigens present in the spores and fragments of hyphae induce allergic responses in sensitized patients. The frequently recognized fungi associated with asthma include Alternaria, Cladosporium, Aspergillus, and Penicillium. With the advent of molecular biology techniques a number of fungal genes encoding relevant allergens have been cloned and the expressed allergens purified and characterized. In this review, we have presented the recent developments, where recombinant allergens have been used in the precise diagnosis of fungal allergy. We have also discussed the role played by these allergens and the T- and B-cell epitopes in the immune mechanism in fungal allergy. 相似文献

Linguistic analysis of short published reports leads to the presentation of an aigorithm that depicts the problem-solving process in terms of a series of evaluative questions. The work shows how reports enable us to define in detail the various stages of problem solving, and it shows that an understanding of these various stages enables us to recognise information structures in written texts; the writing of brief reports of high-priority information on which the whole thinking process is based is thus seen as a vital part of the problem-solving process. One report is analysed in detail to demonstrate the close relationship between information structures in the text and the real-life thought'action process it describes. There is discussion of how paragraphs, sentences and signals within the sentences enable the writer to communicate the information in a conceptual array that represents the actual thought/action process it describes. Educational implications for inter-sentential coherence, discourse analysis, and writing structures, and control of research through written reports are all discussed. 相似文献

ABSTRACTLibrarians of the joint-use North Regional/Broward College (NR/BC) Library had sought opportunities to collaborate. Historically, challenges have arisen in programming for two distinct populations: seniors for the public library and the college library’s students. In recent years, the library successfully capitalized on organizational changes and nationwide attention to media literacy and social justice to create and deliver several well-received collaborations. This article describes the environment in which these initiatives developed and provides tips on collaborations in- and out-side joint-use libraries. This article also addresses the dearth of professional literature on programming advantages in joint-use libraries. 相似文献

The Maltese National Minimum Curriculum published in 1999 sought to strengthen bilingualism by reinforcing the practice of teaching and assessing some subjects in English and others in Maltese. It also pointed out that code-switching should only be used in cases of severe pedagogical difficulties. As a new National Curriculum Framework was being prepared some educators suggested language as a possible barrier to student progress and argued that the traditional practice of teaching subjects such as science in English should be reconsidered. This study investigated language choices, function and code-switching in science lessons. Classroom observations, interviews and focus groups showed that in state schools 12-13 year old students were being taught science predominantly in Maltese while reading, writing and formal assessment were in English. Students who were more exposed to English, irrespective of class stream, used this language more frequently than those who were less exposed to the language. The findings seem to suggest that teachers may be overcautious. While code-switching may initially provide technical terms and serve as a bridge between the two languages, eventually it can give way to a more precise and formal use of English thus ensuring both learning of science and development of bilingualism. 相似文献
