Anxiety disorders linked to thyroid disease, respiratory disease, arthritis and migraine headaches

Anxiety disorders appear to be independently associated with several physical conditions, including thyroid disease, respiratory disease, arthritis and migraine headaches, according to a report in the October 23 issue of Archives of Internal Medicine. This co-occurrence of disorders may significantly increase the risk of disability and negatively affect quality of life.

An enzyme that regulates ether lipid signaling pathways in cancer annotated by multidimensional profiling

Using a combination of enzyme activity and metabolite profiling, we determined that this protein-whose function was previously unknown-serves as a key regulator of a lipid signaling network that contributes to cancer," said Benjamin F. Cravatt, a Scripps Research professor and a member of its Skaggs Institute for Chemical Biology who led the study.
