A compound found in the peels of citrus fruit has the potential to lower cholesterol more effectively than some prescription drugs, and without side effects, according to a study by U.S. and Canadian researchers.  more

Hormone causes body to metabolize stored fat: Research points to potential obesity treatment
In 1999, Drs. Miles Brennan and Ute Hochgeschewender announced their finding that melanocyte-stimulating hormone (MSH) regulates the balance of fat storage and metabolism. In April, they received a patent on the use of MSH analogs -- chemicals that mimic MSH -- as potential treatments for obesity (U.S. Patent #6,716,810). more

'Good guy' blood cells are now suspects in heart disease, diabetes
Until recently, the story on platelets was pretty simple: tiny blood cells, with limited sophistication because they had no nucleus, and their claim to fame was to be a first-responder to a wound site, to promote healthy clotting and prevent infection. Later scientists theorized platelets might be connected to harmful chronic inflammation, but the links were unclear.  more


Fat fighting undermined by over active eating pacemaker
Researchers at the University of Warwick have for the first time been able to detail how and why specific neurons in the brain control the hunger response. They have revealed a set of pacemaker nerve cells in the brain that appear to underlie the drive to feed which itself feeds on a complex web of signals. The level of complexity they have found is such that the system could be much more at risk of serious repercussions from a single error in how those signals are processed than anyone had previously thought. Any number of a range of errors could lead to over activity of these pacemaker cells and explain why many people find difficulty in eating less.  more

New York researchers have found that intensive care unit (ICU) admissions for patients with HIV have significantly increased in the last decade.  more

Growing epidemic of wet age-related macular degeneration
Nearly all retina specialists are greatly alarmed by the increasing number of cases of wet age-related macular degeneration (AMD), the leading cause of severe vision loss and blindness in people over the age of 50, and believe the disease will have a serious impact on the public, according to survey results released today. Despite these concerns, eye experts also conveyed new hope that current research could lead to valuable new treatments. The survey was conducted by Eyetech Pharmaceuticals, Inc. and Pfizer Inc., in consultation with Lighthouse International, a leading resource on vision impairment and rehabilitation.  more

Parents' heart attack or stroke raises risk in their middle-aged children
A study published in the 12 May issue of The Journal of the American Medical Association provides the strongest evidence yet that cardiovascular disease in parents -- particularly at an early age -- is a major predictor of their children having a heart attack or stroke in middle age.  more
