+	This app searches PubMed to find <u>sentences</u> that contain the query terms (e.g., gene symbols) and  a drug addiction related keyword.  <a href="https://github.com/chen42/RatsPub/blob/master/ratspub.py#L95-L129">These keywords</a> belong to the following categories:  
+<ul>
+<li> names of abused drugs, e.g., opioids</li>
+<li> terms describing addiction, e.g., relapse </li>
+<li> key brain regions implicated in addiction, e.g., ventral striatum </li>
+<li> neurotrasmission, e.g., dopaminergic </li>
+<li> synaptic plasticity, e.g., long term potentiation </li> 
+<li> intracellular signaling, e.g., phosphorylation </li>
+</ul>
+
+<br> 
+Live 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 relationships are presented as an interactive <a href="https://js.cytoscape.org" >cytoscape</a> graph. The nodes can be moved around to better reveal the connections.  Clicking on the links will bring up the corresponding sentences in a new browser window.
