Healthcare can be maintained well, when diagnosis is quick, accurate, cost-effective and painless. DNA and RNA based diagnosis
may not reveal the right information for certain diseases. Identification and quantification of proteins and their folding
mechanism are very important in diagnosis of diseases. Small quantities of proteins, which generally escape from detection
and are responsible for the diseases, now can be quantified by protein nanotechniques which aids in the diagnosis. In this
review, we have summarized the recent developments in nanotechnologies such as protein microarrays, biosensors etc. and their
application in diagnosis of diseases at proteomics level have also been discussed. 相似文献

This is a qualitative case study of a collaboration among multiple stakeholders in science education who came together in order to create environmental field trips and the surrounding classroom curriculum. The collaboration involves 4 major facets of science education: formal education at the elementary and university levels, informal education, and educational research. The data were collected by means of observation, semi‐structured interviews, and written document review. This study examines how shared vision developed within the collaboration, the roles the participants played in its evolution, and how this process benefited both the collaboration and each individual collaborator. Several factors significantly affected the progress towards a shared vision and a successful collaboration including time, communication, understanding others' perspectives, dedication and ownership, as well as the collaborative environment. © 2007 Wiley Periodicals, Inc.

Gebhardt's[1] probabilistic model of relevance is examined and found not to represent adequately some characteristics of the relevance judgement process. An alternative model is proposed, which identifies two different types of “error” or probabilistic variation between relevance judgements. The two types arise from, first, the definition of the boundaries of the relevance classes, and secondly the actual assessment of an individual document on the underlying scale (which is assumed to be a continuum). The problems of quantifying the model, and of assessing its implications for retrieval testing, are discussed. 相似文献

The theoretical context of this research is developmental neuropsychology--in particular, the educational implications for the classification of and intervention in specific developmental dyslexia (SDD). Controlled and validated research can help identify optimal teaching methods for groups and individuals. Within this framework, neuropsychological theory can be explored as a medium for improving intervention for pupils with SDD. Neuropsychological stimulation cannot change the macro aspects of the brain but can change its "finetuning" and its response to written text. Within the psycho-neurological approaches, Bakker (1979, 1990, 1998) developed both a diagnostic procedure and empirically investigated intervention procedures. The theory rests on the Balance Model of learning to read, in which differential hemisphere involvement is implicated in beginning and advanced reading. Intervention can take place via hemisphere-specific stimulation using visual or tactile stimulation or hemisphere-alluding stimulation using modified text. Two investigations are presented, one experimental and another clinical. The results support the validity of dyslexia subtyping and the effectiveness of the treatment methods. 相似文献
