Blame the brain for high blood pressure

The controversial idea that one cause of high blood pressure lies within the brain, and not the heart or blood vessels, has been put forward by scientists at the University of Bristol, UK, and is published this week in the journal Hypertension. more  

Researchers report blood DNA can be early predictor of liver cancer

Researchers at Columbia University’s Mailman School of Public Health have discovered a means for early detection of liver cancer. Using DNA isolated from serum samples as a baseline biomarker, the scientists examined changes in certain tumor suppressor genes that have been associated with the development of liver carcinomas. This is the first study to prospectively examine potential biomarkers for early detection of liver cancer in high-risk populations, including those with chronic hepatitis B and C virus infections. more

New imaging method shows whether treatment for advanced prostate cancer is working

Researchers at the University of Michigan Comprehensive Cancer Center have identified a new imaging technique that can measure the effectiveness of treatment for prostate cancer that has spread to the bones. The technique involves measuring diffusion of water within tumors. more  

Antigen-cloning technique may boost efforts to develop a melanoma vaccine

In recent years, researchers have worked to develop a number of vaccines to help the immune system fight tumors. Cancer vaccines are not intended to prevent cancer; rather, they are used to boost immune responses to preexisting tumors. Unlike traditional chemotherapy, vaccines have relatively low toxicity and, potentially, a high degree of efficacy. more

Men who habitually consume alcohol more likely to have a sleep-related breathing disorder  

Increased usual alcohol consumption among men is associated with an increased risk of a mild or worse sleep-related breathing disorder (SRBD), according to a study published in the April 15th issue of the Journal of Clinical Sleep Medicine (JCSM). more

'Night owls' report more insomnia-related symptoms  

Those persons who are labeled a “night owl” report more pathological symptoms related to insomnia, despite many having the opportunity to compensate for their nocturnal sleeplessness by extending their time in bed and being able to gain more total sleep time, according to a study published in the April 15th issue of the Journal of Clinical Sleep Medicine (JCSM). more

Breathing for better lung health

While working to find novel ways to treat the life-threatening disease of cystic fibrosis, researchers at the University of North Carolina have discovered that the rhythmic motion of the lungs during normal breathing is a critical regulator of the clearance of bacteria and other noxious materials. Their research, funded by the Cystic Fibrosis Foundation and the National Institute of Health, is published in the latest issue of The Journal of Physiology. more
