Elevated dental plaque acid is a risk factor that contributes to cavities in children. But eating bran flakes with raisins containing no added sugar does not promote more acid in dental plaque than bran flakes alone, according to new research at the University of Illinois at Chicago. http://www.physorg.com/news180363527.html Medicine & Health Fri, 18 Dec 2009 13:10:02 EST news180363527 Obese patients who lost a moderate amount of weight by eating less and exercising more improved their cardiovascular health, says a study at Washington University School of Medicine in St. Louis. http://www.physorg.com/news179752474.html Medicine & Health Fri, 11 Dec 2009 11:50:01 EST news179752474 (PhysOrg.com) -- A laboratory connection between Alzheimer's disease and brain-wasting diseases such as the human form of mad cow disease has moved into the clinic for what is believed to be the first time, manifesting itself in the brains of patients with a rare inherited disorder. http://www.physorg.com/news179570626.html Medicine & Health Wed, 09 Dec 2009 08:45:01 EST news179570626 By measuring the total gene activity in organs relevant for coronary artery disease (CAD), scientists at the Swedish medical university Karolinska Institutet have identified a module of genes that is important for the recruitment of white blood cells into the atherosclerotic plaque. The findings, which are to be published in the open-access journal PLoS Genetics, suggest that targeting the migration of white blood cells in the development of atherosclerosis may help to reduce the risk for adverse clinical effects such as ischemia and myocardial infarction. http://www.physorg.com/news179147843.html Medicine & Health Fri, 04 Dec 2009 11:30:01 EST news179147843 (PhysOrg.com) -- Scientists have identified the trigger that leads to the arteries becoming damaged in the disease atherosclerosis, which causes heart attacks and strokes, in research published today in the journal Circulation. The authors of the study, from Imperial College London, say their findings suggest that the condition could potentially be treated by blocking the molecule that triggers the damage. The research also suggests that bacteria may be playing a part in the disease. http://www.physorg.com/news178820606.html Medicine & Health Mon, 30 Nov 2009 16:50:06 EST news178820606 University of Sourthern California biomedical engineer and cardiologist Tzung "John" Hsiai hopes to develop a new tool to help clinicians distinguish cardiac emergencies requiring immediate surgery from chronic problems manageable with drugs and lifestyle change. http://www.physorg.com/news178207430.html Medicine & Health Mon, 23 Nov 2009 14:04:31 EST news178207430 A team of U.S., Canadian and Italian scientists led by researchers at Johns Hopkins report evidence from studies in animals and humans supporting a link between Alzheimer's disease and chronic heart failure, two of the 10 leading causes of death in the United States. http://www.physorg.com/news177611563.html Medicine & Health Mon, 16 Nov 2009 16:35:07 EST news177611563 Pooling results from 21 studies, involving 622,381 men and women, researchers at Johns Hopkins have affirmed that migraine headaches are associated with more than twofold higher chances of the most common kind of stroke: those occurring when blood supply to the brain is suddenly cut off by the buildup of plaque or a blood clot. http://www.physorg.com/news177593372.html Medicine & Health Mon, 16 Nov 2009 11:50:04 EST news177593372 If you're among the hundreds of thousands of Americans with clogged kidney arteries, you might want to consider trying medicines before rushing into angioplasty to open them up. The pricey procedure is no more effective and carries surprisingly big risks, a study found. http://www.physorg.com/news177186990.html Medicine & Health Wed, 11 Nov 2009 19:00:02 EST news177186990 (PhysOrg.com) -- Minuscule plaques in the brains of mice with Alzheimer's disease contain much less metal than the brains of affected humans, according to a study conducted at the NSLS. This surprising finding could help researchers pinpoint the effect of metal in the human disease, and, in the long term, lead to targets for drug development or prevention methods. http://www.physorg.com/news176576620.html Medicine & Health Wed, 04 Nov 2009 17:50:01 EST news176576620 Research led by Hernan A. Bazan, MD, Assistant Professor of Surgery, Section of Vascular Surgery, at LSU Health Sciences Center New Orleans School of Medicine, has found that unstable carotid artery plaques - those in danger of rupturing and leading to a stroke - contain more inflammation and significantly less omega-3 fatty acids than asymptomatic plaques. This suggests that increasing the levels of omega-3 fatty acids in carotid artery plaques could either prevent strokes or improve the safety of treatment. This may be accomplished by increasing dietary intake of foods rich in omega-3 fatty acids. http://www.physorg.com/news173620928.html Medicine & Health Thu, 01 Oct 2009 13:20:02 EST news173620928 Will neglecting to brush your teeth damage more than just your smile?

The prevalence of childhood obesity in children has reached alarming levels, even in developing countries. It is estimated that about 1 billion people worldwide are overweight, with 22 millions being under the age of 5 years and 300 million people are obese. By 2010 it is estimated that 26 million children in E.U. countries will be overweight, including 6.4 million who will be obese. http://www.physorg.com/news170942825.html Medicine & Health Mon, 31 Aug 2009 13:20:01 EST news170942825 A major step forward, with important implications for understanding how to reduce the severity of multiple sclerosis, has been made by scientists at the University of Bristol.

New research at Columbia University Medical Center, however, sheds light on why so few plaques in any given individual actually cause a problem. Furthermore, the research has identified a key protein that may promote the conversion from benign to dangerous plaques. http://www.physorg.com/news160751426.html Biology Tue, 05 May 2009 14:11:45 EST news160751426 Taking a new approach to the treatment and prevention of Alzheimer's disease, a research team led by investigators at the Mayo Clinic campus in Florida has shown that druglike compounds can speed up destruction of the amyloid beta (A-beta) proteins that form plaque in the brains of patients with the disorder. http://www.physorg.com/news159611311.html Medicine & Health Wed, 22 Apr 2009 09:29:10 EST news159611311 The legend is that the great rulers of Canaan, the ancient land of Israel, were all men.

The results suggest that patients with CAD should be treated to the most stringent target levels so that they can achieve optimal results from their lipid lowering and antihypertensive therapies. http://www.physorg.com/news157048445.html Medicine & Health Mon, 23 Mar 2009 17:34:38 EST news157048445 Detectives on television shows often spray crime scenes with a compound called luminol to make blood glow.
