PubMed is a good database to start with as it is one of the largest biomedical databases available. Be warned that PubMed does not automatically do a natural language search. Instead of searching like a web browser, PubMed uses Medical Subject Headings, MeSH, to locate a match. As soon as a a term matches a MeSH term the search stops, and the results for the MeSH term are displayed. Since many journal titles match MeSH terms, the database will often never search for a term as a journal title. To search for a journal title, do an advanced search and change the field to "Journal".
