Notas do Editor

  • Single Citation MatcherJournals Database. This database can be used to search for journals by journal title, Medline title abbreviation, or the International Standard Serial Number (ISSN). Clinical QueriesResults of searches on this page are limited to specific clinical research areas using automatic Research Methodology Filters.
  • PubMed has a total of more than twenty 20 citations and MEDLINE contains more than 17 million.OLDMEDLINE for pre-1966 citations. (~2 million citations as of 2010) Citations out-of-scope (e.g., covering plate tectonics or astrophysics) from some journals, primarily general science and general chemistry journals, for which the life sciences articles are indexed for MEDLINE In-process citations with records for articles before indexed with MeSH, added to MEDLINE or converted to out-of-scope status Citations that precede when a journal was selected for MEDLINE indexing (when supplied electronically by the publisher) Some life science journals that submit full text to PubMed Central and may not have been recommended for inclusion in MEDLINE although they have undergone a review by NLM, and some physics journals that were part of a prototype PubMed in the early 1990s
  • Created in 1960Similar in concepts to kw on other systemsMeSH represent a medical concept as well as none-medical Can be broad or narrowCitation is enhanced by MESH
  • Search forBeverages to show the headings / subheadingsSearch for lung cancer review chemotherapy (page 10 or so) to show other things Search for EyelidEyelid is intended under eye because narrower in scope Many heading occurs in different branches
  • http://www.nlm.nih.gov/bsd/disted/video/How to search only with MeSH (try beverages) - look at the handoutTalk about entry termsExplode and majorHow powerful is mapping?Type beveragesNow type beverage*
  • http://www.nlm.nih.gov/bsd/viewlet/search/subject/subject.html
  • What characterizes a good question?well-conceptualizedwell-developedrelevantdirect and clearfocusedincludes all components
  • sleep walking OR sleepwalking OR Sleep Walking Disorderscauses OR reasonschildren OR kids
  • 5. Display your citations  Other options include:Summary (one line); Abstract (citation, abstract, and MeSH headings)MEDLINE (text format which includes field tags, used for importing into bibliographic management software like Reference Manager, RefWorks, or EndNote)Limits Part III B Searching in specific fieldsSelect limits that restrict your search results. Click on Limits above the PubMed query box to refine the search strategy to incorporate the language and year range. Your retrieval will still include all the PubMed in process records.  IMPORTANT - If you add limits for any of the following: age group, publication type, human or animal, gender or subset you will eliminate retrieval of the PubMed in process records that are waiting for full MEDLINE indexing. Remember, the LIMITS you choose stay in effect for every search until you turn them off.2. Talk about the Boolean operators and make sure participants are comfortable with Boolean operators and stress need for operators to be in UPPER CASE Good example of need for upper case operatorsInfection and immunity VERSUS infection AND immunityThe first search yields all hits from the journal Infection and Immunity whereas the other maps to MESH terms and ‘text word’ searches as expected.
  • Pubget - based on PubMed/MEDLINE but gets to the PDF right away, provided the journal is available for free or the subscription is being paid for
  • LigerCat- is a search tool for PubMed that displays tag clouds of key words (MeSH descriptors) associated with the result set. Also, it facilitates the use of plain language queries or molecular sequences to search the PubMed database for articles or to search for journal titles.LigerCat also serves a Publication Data Histogram.
  • PubMed Central (PMC) is the U.S. National Institutes of Health (NIH) free digital archive of biomedical and life sciences journal literature.PubMed Central Canada is a free digital archive of full-text, peer-reviewed health and life sciences literature based on PubMed Central, the archive developed by the US National Library of Medicine. The search interface allows anyone to browse, search and download articles. PMC Canada is a partnership between the National Research Council&apos;s Canada Institute for Scientific and Technical Information (NRC-CISTI), the Canadian Institutes of Health Research (CIHR), and the US National Library of Medicine (NLM).
  • GoPubMed- searching PubMed/MEDLINE with Gene Ontology and MeSHGoPubMed = search for breast cancer to show journal and Mesh Then search for cell to show gene ontology too
  • Quertle - a free, semantic-based search engine for PubMed, full-text articles, NIH Grants, TOXLINE, and news
