Hi,

Just wanted to mention our Dojo (0.4) based Medical Research Interface:
http://www.curehunter.com
(quickly find all the treatment options for any disease)

We also offer an interactive visual medical dictionary:
http://www.curehunter.com/public/dictionary.do
For example: a search for "obesity" will show a strong relationship with "Insulin" and "Exercise" among other drugs and therapies.

Both were built on Dojo 0.4, but we are actively working to rebuild with 1.x... and learning much along the way.
