Development of computations in bioscience and bioinformatics and its application: review of the Symposium of Computations in Bioinformatics and Bioscience (SCBB06).
(33/167)
The first symposium of computations in bioinformatics and bioscience (SCBB06) was held in Hangzhou, China on June 21-22, 2006. Twenty-six peer-reviewed papers were selected for publication in this special issue of BMC Bioinformatics. These papers cover a broad range of topics including bioinformatics theories, algorithms, applications and tool development. The main technical topics contain gene expression analysis, sequence analysis, genome analysis, phylogenetic analysis, gene function prediction, molecular interaction and system biology, genetics and population study, immune strategy, protein structure prediction and proteomics.

Towards answering biological questions with experimental evidence: automatically identifying text that summarize image content in full-text articles.
(34/167)
Images (i.e., figures) are important experimental evidence that are typically reported in bioscience full-text articles. Biologists need to access images to validate research facts and to formulate or to test novel research hypotheses. We propose to build a biological question answering system that provides experimental evidences as answers in response to biological questions. As a first step, we develop natural language processing techniques to identify sentences that summarize image content. (+info)
Trends in life science grid: from computing grid to knowledge grid.
(35/167)
BACKGROUND: Grid computing has great potential to become a standard cyberinfrastructure for life sciences which often require high-performance computing and large data handling which exceeds the computing capacity of a single institution. RESULTS: This survey reviews the latest grid technologies from the viewpoints of computing grid, data grid and knowledge grid. Computing grid technologies have been matured enough to solve high-throughput real-world life scientific problems. Data grid technologies are strong candidates for realizing "resourceome" for bioinformatics. Knowledge grids should be designed not only from sharing explicit knowledge on computers but also from community formulation for sharing tacit knowledge among a community. CONCLUSION: Extending the concept of grid from computing grid to knowledge grid, it is possible to make use of a grid as not only sharable computing resources, but also as time and place in which people work together, create knowledge, and share knowledge and experiences in a community.

Contesting the science/ethics distinction in the review of clinical research.
(36/167)
Recent policy in relation to clinical research proposals in the UK has distinguished between two types of review: scientific and ethical. This distinction has been formally enshrined in the recent changes to research ethics committee (REC) structure and operating procedures, introduced as the UK response to the EU Directive on clinical trials. Recent reviews and recommendations have confirmed the place of the distinction and the separate review processes. However, serious reservations can be mounted about the science/ethics distinction and the policy of separate review that has been built upon it. We argue here that, first, the science/ethics distinction is incoherent, and, second, that RECs should not only be permitted to consider a study's science, but that they have an obligation do so.

Life sciences and biotechnology in China.
(37/167)
Life science and biotechnology have become a top priority in research and development in many countries as the world marches into the new century. China as a developing country with a 1.3 billion population and booming economy is actively meeting the challenge of a new era in this area of research. Owing to support from the government and the scientific community, and reform to improve the infrastructure, recent years have witnessed a rapid progress in some important fields of life science and biotechnology in China, such as genomics and protein sciences, neuroscience, systematics, super-hybrid rice research, stem cell and cloning technology, gene therapy and drug/vaccine development. The planned expansion and development of innovation in related sectors and the area of bioethics are described and discussed. (+info)
Genomic Health, Inc.
(38/167)
Genomic Health, Inc. is a life science company focused on the development and commercialization of genomic-based clinical laboratory services for cancer that allow physicians and patients to make individualized treatment decisions. The company's first commercial product is Oncotype DX, a diagnostic multigene expression test service that has clinical evidence validating its ability to predict the likelihood of breast cancer recurrence, the likelihood of patient survival within 10 years of diagnosis and the likelihood of chemotherapy benefit. Oncotype DX has been extensively evaluated in multiple independent studies involving more than 2600 breast cancer patients, including rigorous validation studies. Genomic Health's goal is to build similar tests that can prove useful across a range of cancer types. (+info)
Using explicit teaching to improve how bioscience students write to the lay public.
(39/167)
The media role model was recently developed to frame how science faculty members can teach their students to write more effectively to lay audiences (14). An Opinion Editorial (Op-Ed) was introduced as a novel assignment for final-year physiology and pharmacology undergraduates. This second phase of this study, reported here, demonstrated the efficacy of explicit teaching of the Op-Ed, using a one-shot, pre-/posttest research design. Baseline writing skills of students were determined from a communication assignment. Students were then explicitly taught how to write an Op-Ed and subsequently wrote an Op-Ed based on a recent, relevant scientific article. Most students achieved higher grades for their Op-Ed following explicit teaching [mean (SD) = 84.4% (9.1%), n = 216] compared with their communication assignment [mean (SD) = 74.7% (11.9%), n = 218]. Improvement in student writing was also evident by an increase in text readability, which mirrored the features of Op-Eds written by professional journalists. A survey of students (n = 142) indicated that most believed that the assignments were valuable and that their ability to write to a lay audience had improved. Members of the lay public were then surveyed for their opinions on student writing. Two assignments were selected from one student whose grades had improved after explicit teaching. Respondents (n = 78) indicated that the Op-Ed was easier to read than the communication assignment. Thus, explicit teaching of the Op-Ed improved the ability of students to write to members of the lay public. (+info)
Combination of didactic lectures and case-oriented problem-solving tutorials toward better learning: perceptions of students from a conventional medical curriculum.
(40/167)
The Department of Physiology of Pramukhswami Medical College at Anand, Gujarat, India, started using problem-based learning in a modified way along with didactic lectures to improve students' understanding and motivate them toward self-directed study. After the didactic lectures were taken for a particular system, clearly defined short clinical problems related to that system were given to the students in the tutorial classes. Each tutor was assigned three to four groups of five to six students each. Problems were accompanied with relevant questions so as to streamline the thought processes of the first-year undergraduates. The tutor then facilitated the study process, and the students discussed among themselves to derive their solutions. At the end of the sessions, feedback was taken from the students through a planned questionnaire on a three-point scale. Of a total of 278 students over a span of 3 yr from 1999 to 2002, 74.4% of students favored a judicious mixture of didactic lectures and case-oriented problem solving in tutorial classes to be an efficient modality in understanding a system under study, and 84% of students stated the mixture of didactic lectures and case-oriented problem solving to be beneficial in relating a clinical condition to the basic mechanism; 82% of students believed that this module helped with better interactions among their batch mates, and 77.2% of students hoped to perform better in the university examination due to this new teaching/learning modality. They also expressed that this gave them ample motivation to do self-directed learning. It may therefore be concluded from the results of the present study that it is possible to have a problem-based learning module in the form of case-oriented problem-solving tutorials coexistent with the traditional didactic lecture module in the first year of medical education under a conventional curriculum.
