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 Researchers at Mount Sinai School of Medicine set out to address a question that has been challenging scientists for years: How do dietary restriction -and the reverse, overconsumption -produce protective effects against aging and disease? http://www.physorg.com/news177772576.html Medicine & Health Wed, 18 Nov 2009 13:30:03 EST news177772576 (PhysOrg.com) -- While applauding findings that an Easter Island compound extends the lives of middle-aged mice, University of Washington longevity researchers caution that healthy people shouldn't start taking the drug in the hopes of extending their own life spans -- at least not yet. http://www.physorg.com/news166454313.html Medicine & Health Fri, 10 Jul 2009 14:19:11 EST news166454313 A protein that plays a key role in tumor formation, oxygen metabolism and inflammation is involved in a pathway that extends lifespan by dietary restriction. The finding, which appears in the May 22, 2009 edition of the on-line journal PLoS Genetics, provides a new understanding of how dietary restriction contributes to longevity and cancer prevention and gives scientists new targets for developing and testing drugs that could extend the healthy years of life. http://www.physorg.com/news162215715.html Medicine & Health Fri, 22 May 2009 12:55:40 EST news162215715 A biochemical pathway that helps keep cells alive when oxygen is low also plays a role in longevity and resistance against some diseases of old age, according to a report to be published April 16 in the journal Science. http://www.physorg.com/news159110794.html Medicine & Health Thu, 16 Apr 2009 14:26:57 EST news159110794 Whitehead Institute researchers have pinpointed a cellular pathway that determines whether cancerous tumors respond to dietary restriction during their development. http://www.physorg.com/news156000728.html Medicine & Health Wed, 11 Mar 2009 14:32:51 EST news156000728 Large doses of a red wine ingredient can ward off many of the vagaries of aging in mice who begin taking it at midlife, according to a new report published online on July 3rd in Cell Metabolism, a Cell Press publication. Those health improvements of the chemical known as resveratrol -including cardiovascular benefits, greater motor coordination, reduced cataracts and better bone density -come without necessarily extending the animals' lifespan. http://www.physorg.com/news134309666.html Medicine & Health Thu, 03 Jul 2008 13:14:26 EST news134309666
