Non-smokers live longer and have less cardiovascular disease than those who smoke, according to a 30-year follow-up study of 54,000 men and women in Norway. Smoking, say the investigators, is "strongly" related to cardiovascular morbidity and mortality from various causes. http://www.physorg.com/news160995294.html Medicine & Health Fri, 08 May 2009 09:55:24 EST news160995294 School children as young as 11 can benefit from a daily exercise programme in reducing their levels of several known risk factors for cardiovascular disease. An ongoing study, which began four years ago in the German city of Leipzig, shows already that children assigned to daily exercise lessons reduced their overall prevalence of obesity, improved their exercise capacity, increased their levels of HDL-cholesterol, and reduced their systolic blood pressure. http://www.physorg.com/news160985864.html Medicine & Health Fri, 08 May 2009 07:18:26 EST news160985864 Cell biologists have found a more filling substitute for caloric restriction in extending the life span of simple organisms. In a study published May 8 in the open-access journal PLoS Genetics, researchers from the University of Southern California Andrus Gerontology Center show that yeast cells maintained on a glycerol diet live twice as long as normal -- as long as yeast cells on a severe caloric-restriction diet. They are also more resistant to cell damage. http://www.physorg.com/news160985198.html Biology Fri, 08 May 2009 07:07:17 EST news160985198 Increased daily exercise can prevent diabetes and cardiovascular disease in obese women, but getting started and maintaining new habits is a challenge.

In the research report, scientists from the University of Utah show that rat fetuses receiving poor nutrition in the womb become genetically primed to be born into an environment lacking proper nutrition. As a result of this genetic adaptation, the rats were likely to grow to smaller sizes than their normal counterparts. At the same time, they were also at higher risk for a host of health problems throughout their lives, such as diabetes, growth retardation, cardiovascular disease, obesity, and neurodevelopmental delays, among others. Although the study involved rats, the genes and cellular mechanisms involved are the same as those in humans. http://www.physorg.com/news158856122.html Medicine & Health Mon, 13 Apr 2009 15:43:43 EST news158856122 New research from Trinity College Dublin published in this month's Annals of Surgery points to a potentially significant advance in the treatment of patients undergoing major cancer surgery. The study was carried out by the oesophageal research group at Trinity College Dublin and St James's Hospital. A randomised controlled trial showed omega-3 fatty acids given as part of an oral nutritional supplement resulted in the preservation of muscle mass in patients undergoing surgery for oesopahageal cancer, a procedure normally associated with significant weight loss and quality of life issues. http://www.physorg.com/news158583664.html Medicine & Health Fri, 10 Apr 2009 12:01:35 EST news158583664 In its quest to rid consumer products of a potent neurotoxin, an Oakland environmental group on Tuesday warned nearly 20 major retailers and manufacturers that they're selling women's purses, wallets, tote bags and other accessories with lead levels exceeding California state standards. http://www.physorg.com/news158494590.html Medicine & Health Thu, 09 Apr 2009 11:17:53 EST news158494590 Studies done with laboratory rats suggest that supplementation of their diet with lipoic acid had a significant effect in lowering triglycerides, which along with cholesterol levels and blood pressure are one of the key risk factors in cardiovascular disease. http://www.physorg.com/news157653803.html Chemistry Mon, 30 Mar 2009 17:43:46 EST news157653803 High concentrations of blood fats known as triglycerides are common in the United States, according to a report in the March 23 issue of Archives of Internal Medicine.

A Japanese examination of the effects of social support on the relationship between drinking and cardiovascular disease has found that the health benefits of light-to-moderate drinking are more pronounced in men with greater social support. http://www.physorg.com/news156705054.html Medicine & Health Thu, 19 Mar 2009 18:11:09 EST news156705054 Millions more patients could benefit from taking statins, drugs typically used to prevent heart attacks and strokes, than current prescribing guidelines suggest, Johns Hopkins doctors report in a new study. http://www.physorg.com/news156614761.html Medicine & Health Wed, 18 Mar 2009 17:06:43 EST news156614761 An important clinical repercussion in the treatment of epilepsy has been discovered by a research team led by Scott Mintzer, M.D., assistant professor in the Department of Neurology and the Jefferson Comprehensive Epilepsy Center at Jefferson Medical College of Thomas Jefferson University. The team has determined that two of the most commonly prescribed anti-seizure medications may lead to significantly increased levels of cholesterol, C-reactive protein and other markers of cardiovascular disease risk. The finding - set to be published in the March 18th online edition of Annals of Neurology - may help doctors manage the care of patients with seizures more effectively by prescribing different anti-seizure medications that will not adversely affect cardiovascular health. http://www.physorg.com/news156607822.html Medicine & Health Wed, 18 Mar 2009 15:10:54 EST news156607822 Scientists at the Gladstone Institutes of Cardiovascular Disease (GICD) have found that a key enzyme involved in absorbing fat may also be a key to reducing it. The enzyme, acyl CoA: monoacylglycerol acyltransferase 2 or Mgat2 is found in the intestines and plays an important part in the uptake of dietary fat by catalyzing a critical step in making triglyceride, a kind of fat. Triglyceride accounts for nearly one-third of the fat eaten by people in developed countries. http://www.physorg.com/news156419535.html Medicine & Health Mon, 16 Mar 2009 10:53:09 EST news156419535 New results from the Women's Health Initiative (WHI) Observational Study provide additional evidence that aspirin may reduce the risk of death in postmenopausal women who have heart disease or who have had a stroke. Jacques Rossouw, M.D., chief of the Women's Health Initiative Branch at the National Heart, Lung, and Blood Institute (NHLBI), is available to comment on these findings. NHLBI, part of the National Institutes of Health, funded the research. http://www.physorg.com/news156099931.html Medicine & Health Thu, 12 Mar 2009 18:06:24 EST news156099931 The landmark Framingham Heart Study (FHS) is launching a major initiative to discover risk factors and markers that could lead to new blood tests to identify individuals at high risk of heart disease and stroke.
