It's good news that we are living longer, but bad news that the longer we live, the better our odds of developing late-onset Alzheimer's disease. Researchers now report that omega-3 fatty acid docosahexaenoic acid, found in fish oil, increases the production of LR11, a protein that is found at reduced levels in Alzheimer's patients and which is known to destroy the the "plaques" associated with the disease.

In the latest edition of the New England Journal of Medicine, Dr. Eric Hoffman posits that the results of a clinical trial involving a new treatment for Duchenne muscular dystrophy provides a proof-of-principle for personalized molecular medicine. He writes that advances allowing for systemic delivery of such drugs and provide proof of no long term toxicity for recipients are necessary but will likely come in short order. Moving forward, FDA regulations will prove critical for appropriate labeling and marketing of such personalized treatments.

Scientists have developed a microchip-based device that can isolate, enumerate and analyze circulating tumor cells from a blood sample. The new device -- called the "CTC-chip" -- has the potential to be an invaluable tool for monitoring and guiding cancer treatment.

New data from six U.S. sites show a dramatic shift by men acutely infected with HIV to choose to have unprotected intercourse only with other HIV-infected partners.

Breeding mice with a gene for a cellular receptor that can be turned on and off-at will-not only enabled researchers to show how prostate cancer progresses, but also provides a model for studying when a drug targeting a gene will have an effect on the cancer.

There are currently no standards of color choice for hospitals using color-coded wristbands, and each hospital has a different set of colors for different indications. This lack of standardization creates the potential for errors. For example, some hospitals have used yellow to signify “Do Not Resuscitate,” leading to several near-misses with patients wearing yellow Lance Armstrong “Livestrong” bracelets.

In the first survey to specifically measure hospital pediatric preparedness, a team of Los Angeles Biomedical Research Institute researchers found few US emergency rooms are properly equipped for children.

New research at Wake Forest University Baptist Medical Center suggests that transplanting kidneys from donors who died after cardiac arrest -- which used to be considered taboo -- offers a promising approach to increase the donor pool.

The world's most powerful medical magnetic resonance imaging machine, the 9.4 Tesla at the University of Illinois at Chicago, has successfully completed safety trials and may soon offer physicians a real-time view of biological processes in the human brain.

Tears in the aorta which affect thousands of people each year coast to coast, may soon be treated with a much less invasive technique that could dramatically improve patients' chances of survival. A national study is exploring a new minimally invasive method that could spare patients the trauma and risk of open chest surgery.
