1 Databases – especially for literature June 17, 2008 Learning objectives: Become aware of the general arrangement of biological data in the public databases. Be able to retrieve information on a particular subject in the literature. Databases National Center for Biotechnology Information (NCBI) Databases outside of NCBI Writing assignment

2 Today Announcements Due dates Wed, 9 AM, inclass and homework from Molecular Life Science Review Friday PM – know whether you prefer the patent or primary article writing assignment

3 Today Schedule “Finish” last part of Molecular Life Science review Heme binding domain in sickle and wt Homologies in evolutionary and structural/functional sense * vs. : in ClustalW Lecture on Lit Databases Workshop for Lit Databases

4 Who... Has used PubMed? Has done a search using PubMed Has NCBI report to them weekly on new articles regarding a specific topic? Has published an article in a journal listed on PubMed?

10 Medline databases (the part the “user” doesn’t see) Handbook on PubMed/MedlinePubMed/Medline Medline Developer Tools Record-describes a publication Journal article Book Book chapter Meeting abstract Records are subdivided into fields Author Title Publication Name Language Each field has a two-letter (or more) label associated with it. This label tags the field.

13 Medical Subject Headings (MeSH) MeSH is NLM's controlled vocabulary used for indexing articles for MEDLINE. MeSH terminology provides a consistent way to retrieve information that may use different terminology for the same concepts.MeSH Who has published?

14 OMIM-Online Mendelian Inheritance in Man A catalog of human genes linked to diseases Started by Victor A. McKusick at Johns Hopkins University A good place to start when you want to research a certain disease or biological molecule associated with a disease. This database is cross-referenced to PubMed and other NCBI-based databases

15 In-Class Assignment Before beginning this assignment, decide on a molecular topic in which you are interested and keep it in mind as you work through the tutorials. Complete the PubMed tutorial, starting at Be sure to use the menu at left, and complete at least: Using PubMed My NCBI For each menu item, use “next” arrow to progress through the tutorial. You will automatically be moved from tab to tab. We will confirm that the next two items have been completed in class on Thursday. Set up a My NCBI account to keep a running tab on your favorite subject Make at least one of your NCBI weekly searches relevant to your internship. elp.My_NCBI elp.My_NCBI Bring up you r My NCBI page, print scrreen to a word document, print it out, and hand in..
