Online Access to Very Large Chemical Structure Images Enhanced on STN

Save time and increase efficiency with the enhanced ability to display very large chemical structure images in STN. Previously, very large chemical structure images were not available for display. Instead of "STRUCTURE DIAGRAM TOO LARGE FOR DISPLAY - AVAILABLE VIA OFFLINE PRINT," these images will now display online and appear in transcripts.

This enhancement is available to customers using STN on the Web and STN Express, Version 8.5. Customers using STN Express, Version 8.4 or earlier will need to upgrade to take advantage of this enhancement.

Structure Graphics Have Been Added to Abstracts for MARPAT and CA/CAplus on SciFinder and STN

View chemical substance images for more patent records with the addition of over 79,000 structure graphics (issue graphics) to the MARPAT and CA/CAplus databases on STN and SciFinder.

The enhanced availability of these images increases customers access to information regarding the structure of chemical entities disclosed in Markush patents. Structure graphics are now available for more than 75 percent of MARPAT records.

MEDLINE Reload - Updated MeSH Vocabulary and Two New Fields on STN

New features and enhancements are now available with the STN reload of MEDlars onLINE (MEDLINE/LMEDLINE), produced by the U.S. National Library of Medicine (NLM).

Revised 2012 MeSH
The revised MeSH (Medical Subject Headings) vocabulary for 2012 was loaded on STN on December 11, 2011. MEDLINE records have been completely updated using the 2012 version of the MeSH vocabulary. 

Changes to the MeSH vocabulary include:

• 454 new terms (http://www.nlm.nih.gov/mesh/newd.html)
  
• 42 terms replaced by more up-to-date vocabulary (http://www.nlm.nih.gov/mesh/prefterm_change.html)
  
• 15 deleted terms (http://www.nlm.nih.gov/mesh/deleted.html)
  

For the most comprehensive searching in MEDLINE, consult the updated MeSH thesaurus for new or better search terms.

Review your SDIs running in MEDLINE with the new MeSH vocabulary to determine whether updating is necessary.

New Search Fields
The new RE.EX and RAU.EX search fields provide expanded capabilities for searching cited reference and cited reference author information.

RAU.EX Search Field
MEDLINE searches using the new RAU.EX field automatically retrieve reference author names with single initials even when multiple initials are used in the search query. This expands the number of results retrieved. 
 
 

The new RE.EX field for cited references works similarly to the RAU.EX search field for cited reference authors.

Evaluate the relevance of additional results retrieved using RE.EX and RAU.EX.
