ToxFile 2013 reload completed
The annual ToxFile® reload on legacy Dialog is completed. MeSH®
descriptors in all records throughout the file now match the 2013 MEDLINE®
thesaurus already available in File 156.
You may wish to consider updating your search strategies to take into
account changes in the MeSH thesaurus. MeSH vocabulary changes for 2013
can be found at http://www.nlm.nih.gov/mesh/introduction.html#changes.
