(PhysOrg.com) -- A new paper from MIT biology professor Leonard Guarente strengthens the link between longevity proteins called sirtuins and the lifespan-extending effects of calorie restriction. http://www.physorg.com/news180036887.html Medicine & Health Mon, 14 Dec 2009 19:00:02 EST news180036887 Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research funded by the Wellcome Trust and Research into Ageing suggests. http://www.physorg.com/news178984012.html Medicine & Health Wed, 02 Dec 2009 14:40:02 EST news178984012 Resveratrol, a molecule found in red grapes, has been shown to improve diabetes when delivered orally to rodents. Until now, however, little has been known about how these beneficial changes are mediated in the body. A new study accepted for publication in Endocrinology, a journal of The Endocrine Society, shows that the brain plays a key role in mediating resveratrol's anti-diabetic actions, potentially paving the way for future orally-delivered diabetes medications that target the brain. http://www.physorg.com/news174050258.html Medicine & Health Tue, 06 Oct 2009 12:19:02 EST news174050258 Scientists have managed to extend the lifespan of mice by up to a fifth and reduce the number of age-related diseases the animals suffer. The research, which involved blocking a key molecular pathway, mimics the health benefits of reducing calorie intake and suggests that drug treatments for ageing and age-related diseases are feasible. http://www.physorg.com/news173627386.html Medicine & Health Thu, 01 Oct 2009 15:40:03 EST news173627386 (PhysOrg.com) -- Scientists have long known that calorie restriction increases longevity in animals but at an evolutionary cost - the animals become infertile. http://www.physorg.com/news172776461.html Medicine & Health Mon, 21 Sep 2009 18:28:18 EST news172776461 Scientific dogma has long asserted that females are born with their entire lifetime's supply of eggs, and once they're gone, they're gone. New findings by researchers at Fred Hutchinson Cancer Research Center, published online Aug. 27 in Science, suggest that in nematode worms, at least, this does not hold true. http://www.physorg.com/news170601450.html Biology Thu, 27 Aug 2009 14:18:04 EST news170601450 How you eat may be just as important as how much you eat, if mice studies are any clue. http://www.physorg.com/news168612990.html Medicine & Health Tue, 04 Aug 2009 14:20:08 EST news168612990 Experiment after experiment confirms that a diet on the brink of starvation expands lifespan in mice and many other species. But the molecular mechanism that links nutrition and survival is still poorly understood. Now, researchers at the Salk Institute for Biological Studies have identified a pivotal role for two enzymes that work together to determine the health benefits of diet restriction. http://www.physorg.com/news165068957.html Biology Wed, 24 Jun 2009 15:00:04 EST news165068957 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 Moderate calorie restriction causes temporal changes in the liver and skeletal muscle metabolism, whereas moderate weight loss affects muscle, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. In addition, researchers found that short-term calorie restriction (CR) with a low-carbohydrate diet caused a greater change in liver fat content and metabolic function than short-term CR with a high-carbohydrate diet. http://www.physorg.com/news160675334.html Medicine & Health Mon, 04 May 2009 17:02:42 EST news160675334 Calorie restriction, a diet that is low in calories and high in nutrition, may not be as effective at extending life in people as it is in rodents, according to scientists at Washington University School of Medicine in St. Louis. http://www.physorg.com/news141484846.html Biology Wed, 24 Sep 2008 14:20:46 EST news141484846 Young adults who follow a diet that is low in calories but nutritionally sound for six months appear to lose weight and fat without significant bone loss, according to a report in the September 22 issue of Archives of Internal Medicine. http://www.physorg.com/news141318507.html Medicine & Health Mon, 22 Sep 2008 16:08:26 EST news141318507 Want to slow the signs of aging and live longer? New Saint Louis University research suggests cutting back on calories could be a promising strategy. http://www.physorg.com/news134302762.html Medicine & Health Thu, 03 Jul 2008 11:19:22 EST news134302762
