WASHINGTON – More than one-third of the world's population suffers from hypertension (commonly known as high blood pressure) and cardiovascular disease (disorders that affect the heart and/or blood vessels). The U.S. Agency for Healthcare Quality and Research has reported that Americans spent $29 billion for non-prescription cardiovascular drugs alone in 2008. With the number of individuals afflicted on the rise, and the costs for treatment on the increase, scientists and policymakers are looking for new approaches to combat these disorders.

In a development that holds intriguing possibilities for the future of industrial catalysis, as well as for such promising clean green energy technologies as artificial photosynthesis, researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have created bilayered nanocrystals of ametal-metal oxide that are the first to feature multiple catalytic sites on nanocrystal interfaces. These multiple catalytic sites allow for multiple, sequential catalytic reactions to be carried out selectively and in tandem.
Improved management of chronic pain can significantly reduce disability in older adults, according to the latest issue of the WHAT'S HOT newsletter from The Gerontological Society of America (GSA).
An intensive program that taught low-income, poorly educated diabetics to better manage their disease resulted in significantly improved long-term blood sugar control, according to Johns Hopkins researchers who designed and implemented the program.
A gene thought to be associated with cancer development can be a tumor suppressor gene in mice, researchers have discovered. Understanding which genes are involved in spreading cancer could lead to future therapies.
The turmoil in oil-producing nations is triggering turmoil at home, as rising oil prices force Americans to pay more at the pump. Meanwhile, there's a growing industry that's promising jobs and access to cheaper energy resources on American soil, but it's not without its controversy. Deborah Kittner, a University of Cincinnati doctoral student in geography, presents, "What's the Fracking Problem? Extraction Industry's Neglect of the Locals in the Pennsylvania Marcellus Region," at the annual meeting of the Association of American Geographers.
Fear of the unknown is one of the greatest issues facing patients with glaucoma - the second leading cause of blindness worldwide after cataracts - according to research in the April issue of the Journal of Advanced Nursing. People also worry about how the eye disease, which can be hereditary, will affect other members of their family.
Researchers spoke to 24 people with glaucoma, which can lead to severe restriction of the visual field and irreversible blindness if it is not detected early enough and successfully treated.
Denver, CO., April 11, 2011 – Research to be presented this week at The Federation of American Societies for Experimental Biology (FASEB) Conference in Washington, D.C., demonstrates that consumption of white potatoes (non-fried) by children does not displace other vegetables from children's meals. In fact, meals that contain white potatoes contain more servings of other vegetables, and are significantly higher in potassium, fiber and vitamin C. Both potassium and fiber were identified as nutrients of concern in the 2010 Dietary Guidelines, released February 2011.
Forty-five percent of the 32,000 Americans who take their own lives each year visit their primary care provider within one month of their death. Ninety percent have a mental health or substance abuse disorder, or both. Yet only in the last decade has suicide been considered a preventable public health problem.
WASHINGTON, DC (April 11, 2011) – Drinking 100 percent fruit juices could have protective health benefits similar to those of whole fruits, according to research presented in a literature review yesterday at the 2011 Experimental Biology (EB) meeting.
Highlights from a new report summarizing recent research on the potential benefits of fruit juice suggest a positive association between intake of 100 percent juice and reduced risk for several chronic diseases, including cancer, markers for cardiovascular disease and cognitive decline.
Storing fruits and vegetables in ozone-enriched environments reduces spoilage explains a scientist at the Society for General Microbiology's Spring Conference in Harrogate. Dr Ian Singleton explains how ozone treatment could be a safe, effective replacement for pesticides as it leaves no residue on foods.
The benefits of blueberry consumption have been demonstrated in several nutrition studies, more specifically the cardio-protective benefits derived from their high polyphenol content. Blueberries have shown potential to have a positive effect on everything from aging to metabolic syndrome. Recently, a researcher from Texas Woman's University (TWU) in Denton, TX, examined whether blueberries could play a role in reducing one of the world's greatest health challenges: obesity.
SAN DIEGO, April 8, 2011 -- A reformed Medicaid program must put coordinated primary care at the forefront of its efforts, the American College of Physicians (ACP) said in a new position paper released today at Internal Medicine 2011, ACP's annual scientific meeting. Medicaid and Health Care Reform highlights how primary care physicians will assume a major role in providing care to Medicaid beneficiaries.
The hand moves the computer mouse, but the cursor doesn't comply. The cursor doesn't go where told.
The hand tries again. The cursor shoots past the intended target.
The hand tries a third time – and the cursor loops farther from the target than where it started. And the user is frustrated.
So it often goes for computer users whose motor disabilities prevent them from easily using a mouse.
STANFORD, Calif. — Doctors at the Veterans Affairs Boston Healthcare System are testing a new kind of clinical trial that's not only less costly but guides doctors to switch to the best treatment even before the trial is completed. The new approach — called a point-of-care clinical trial — was developed by Stanford University biostatistician Philip Lavori, PhD, and a Boston-based team as an alternative to expensive, lengthy, double-blind, placebo-controlled clinical trials to compare drugs and procedures that are already in regular use.
