Raynaud's phenomenon (RAY-noz), in medicine, is discoloration of the fingers or toes due to emotional stress or cold in a characteristic pattern in time: white, blue and red.

It is associated with a large number of diseases (mainly forms of vasculitis and hence belonging to rheumatology), but is idiopathic in most sufferers and is then called Raynaud's disease. Raynaud's phenomenon has also been observed in patients after receiving chemotherapy, particularly after regimens that included bleomycin.

The condition is painful and potentially dangerous for those who suffer from it. The primary cause of the pain and discoloration of the affected extremeties is vasospasm.

Imaging Technique Allows Researchers to Monitor Protein Changes in Mouse Tumors
Wed, 01 Jul 2009 12:05:00 -0400
A new imaging technique can monitor, in living mice, the HER2 protein found in above-normal amounts in many cases of breast cancer as well as some ovarian, prostate and lung cancers. This new approach, once validated in mice and pending further experiments, could provide a real-time noninvasive method for identifying tumors in humans who express HER2 and who would be candidates for targeted therapy directed against this protein. It may also provide real-time information that will help clinicians optimize treatment for individual patients. The study, published in the July 2009 issue of The Journal of Nuclear Medicine, was conducted by researchers at the National Cancer Institute (NCI) and the National Institute of Biomedical Imaging and Bioengineering, both parts of the National Institutes of Health.

The influenza virus that wreaked worldwide havoc in 1918-1919 founded a viral dynasty that persists to this day, according to scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. In an article published online on June 29 by the New England Journal of Medicine, authors Anthony S. Fauci, M.D., Jeffery K. Taubenberger, M.D., Ph.D., and David M. Morens, M.D., argue that we have lived in an influenza pandemic era since 1918, and they describe how the novel 2009 H1N1 virus now circling the globe is yet another manifestation of this enduring viral family.
