How to find keywords?

• A list of 3-10 keywords must be provided for indexing purposes. All keywords should be provided according to the MeSH terms at: http://www.nlm.nih.gov/mesh/MBrowser.html.
• The preferred expression is indicated by the label "MeSH Heading" and not "Entry Term". The desired terms may then be copied from the MeSH Browser. Another way of finding appropriate headings is to search PubMed to find articles on similar topics, and review the MeSH headings assigned to those articles.
