 	This app searches PubMed to find <i>sentences</i> that contain the query terms (e.g., gene symbols) and  <a href="https://github.com/chen42/RatsPub/blob/master/ratspub.py#L95-L129">keywords</a> related to drug addiction.

-Searches are conducted through PubMed to get relevant PMIDs, which are then used to retrieve the abstracts from a <a href="https://dataguide.nlm.nih.gov/edirect/archive.html">local archive</a>. The gene-keyword relationships are presented as an interactive <a href="https://js.cytoscape.org" >cytoscape</a> graph. The nodes can be moved to better reveal the connections.  Tap on the links will bring up the corresponding sentences in a new browser window.
