<h1>NCBI MeSH<span class="registered">&#174;</span> Database Updated</h1>
<p class="editorsnote"><a name="note"></a><em>[Editor's note: These changes were implemented in PubMed on February 14, 2011.]</em></p>
<p>
The National Center for Biotechnology Information (NCBI) Medical Subject Headings (MeSH) Database will soon be redesigned to provide users with the same streamlined interface now available in PubMed<span class="registered">&#174;</span> and the NLM<span class="registered">&#174;</span> Catalog (see <a href="#fig1">Figure 1</a>).
</p>
<p>
<a href="//www.nlm.nih.gov/mesh/meshhome.html">MeSH</a> is the National Library of Medicine controlled vocabulary used for indexing articles for PubMed.
</p>
<div class="figure" style="width: 624px;"> <a name="fig1" id="fig1"><img src="graphics/mesh_db_fig1.gif" alt="Screen capture ofMeSH database homepage." title="Screen capture of MeSH database homepage" width="622" height="312" /><br /> <strong>Figure 1: MeSH Database homepage.</strong></a> </div>
<h2>Autocomplete Feature Added</h2>
<p>
"Suggestions" has been replaced by an autocomplete feature (see <a href="#fig2">Figure 2</a>).
</p>
<div class="figure" style="width: 624px;"> <a name="fig2" id="fig2"><img src="graphics/mesh_db_fig2.gif" alt="Screen capture of MeSH search box with autocomplete." title="Screen capture of MeSH search box with autocomplete" width="622" height="310" /><br /> <strong>Figure 2: MeSH search box with autocomplete.</strong></a> </div>
<h2>Launching PubMed searches from MeSH</h2>
<p>
To build a PubMed search from MeSH, run a search, select terms using the check boxes, and then click "Add to search builder" in the PubMed search builder to the right of the results. You may continue searching and including additional terms to the PubMed search builder using "Add to search builder" and the Boolean pull-down menu. When you are finished, click "Search PubMed" (see <a href="#fig3">Figure 3</a>).
</p>
<div class="figure" style="width: 624px;"> <a name="fig3" id="fig3"><img src="graphics/mesh_db_fig3.gif" alt="Screen capture of Populating the PubMed search builder." title="Screen capture of Populating the PubMed search builder" width="622" height="394" /><br /> <strong>Figure 3: Populating the PubMed search builder.</strong></a> </div>
<p>
To add subheadings or specific search requirements for terms, click the term from the Summary display to view the Full display, and then check the required selections, for example, Restrict to MeSH Major Topic (see <a href="#fig4">Figure 4</a>) before clicking Add to search builder.
When viewing the MeSH record in the Full format, you can search the terms in PubMed, Clinical Queries, and the NLM MeSH Browser using the links under "All links from this record." If, however, you select check boxes, for example, for subheadings, you must use the search builder as described above.

<h2>Supplementary Concepts</h2>
<p>
The Substance Name field was renamed to Supplementary Concepts; terms will be tagged with the new name, for example, lead nitrate [Supplementary Concept] (see <a href="#fig5">Figure 5</a>).</p>
<div class="figure" style="width: 624px;"> <a name="fig5" id="fig5"><img src="graphics/mesh_db_fig5.gif" alt="Screen capture of citationcontext menu." title="Screen capture of citation context menu" width="622" height="369" /><br /> <strong>Figure 5: Lead nitrate Supplementary Concept record.</strong></a> </div>
