Anti-inflammatory approach suppresses cancer metastasis in animal models

An anti-inflammatory drug called ketorolac, given before surgery, can promote long-term survival in animal models of cancer metastasis, a team of scientists has found. The research suggests that flanking chemotherapy with ketorolac or similar drugs -- an approach that is distinct from previous anti-inflammatory cancer prevention efforts -- can unleash anti-tumor immunity. The findings, published in Journal of Clinical Investigation, also provide a mechanistic explanation for the anti-metastatic effects of ketorolac, previously observed in human Read more

I3 Venture awards info

Emory is full of fledgling biomedical proto-companies. Some of them are actual corporations with employees, while others are ideas that need a push to get them to that point. Along with the companies highlighted by the Emory Biotech Consulting Club, Dean Sukhatme’s recent announcement of five I3 Venture research awards gives more examples of early stage research projects with commercial potential. This is the third round of the I3 awards; the first two were Wow! Read more

Take heart, Goldilocks -- and get more sleep

Sleeping too little or too much increases the risk of cardiovascular events and death in those with coronary artery disease, according to a new paper from Emory Clinical Cardiovascular Research Institute. Others have observed a similar U-shaped risk curve in the general population, with respect to sleep duration. The new study, published in American Journal of Cardiology, extends the finding to people who were being evaluated for coronary artery disease. Arshed Quyyumi, MD and colleagues analyzed Read more

Old-school medicine: relief of skin irritation with gentian violet

In the September issue of the Journal of the American Academy of Dermatology, Jack Arbiser and colleagues describe the use of gentian violet to provide some relief to a patient who came to the emergency room with a painful skin irritation. Arbiser is a professor of dermatology at Emory University School of Medicine.

A coal-tar dye which is inexpensive and available over the counter, gentian violet was first synthesized in the 19th century. It has been used as a component of paper ink, a histological stain, and an antibiotic or antifungal agent, especially before the arrival of penicillin.

“Clinicians should not forget about gentian violet for immediate pain relief and antibiotic coverage,” the authors conclude in their case report.

Biopsy of the patient's irritated skin shows that the gene angiopoetin-2 (dark brown) is turned on

In addition to its antibiotic properties, Arbiser reports that gentian violet has antiinflammatory effects, possibly because of its inhibition of the enzyme NADPH oxidase and the gene angiopoetin-2.
