The current version of the 'loadabbrevs.js' file contains 24'682 IsoAbbr
and 23'369 MedAbbr abbreviations from NCBI/Entrez-PubMed database
(http://www.ncbi.nlm.nih.gov/entrez/citmatch_help.html#JournalLists).

Copy and replace the original 'loadabbrevs.js' and 'runcites.js' files in
'<Mendeley_desktop_running_directory>/citeproc-js' repertory by those in the
'NCBI_Entrez_Abbreviations_2.zip' archive. If you wish to use
IsoAbbr nomenclature, copy 'runcites.js' from IsoAbbr directory. Otherwise,
for MedAbbr nomenclature, copy 'runcites.js' from MedAbbr directory.

In order that journal names are properly abbreviated, it is important that
the full journal name in your Mendeley Desktop library matches NCBI/Entrez-PubMed
standards. So, an update of the entries by clicking on the 'Lookup' icon next
to PMID field will ensure that the full journal name is correctly spelled
and can be abbreviated.

If journal names are not properly abbreviated, check also that the citation
style (*.CSL file) that you are using specifies form="short" for "container-title"
(e.g.: <text variable="container-title" form="short"/> otherwise journal names
will not be abbreviated.
