(PhysOrg.com) -- The link between obesity and osteoarthritis may be more than just the wear and tear on the skeleton caused by added weight. http://www.physorg.com/news173420426.html Medicine & Health Tue, 29 Sep 2009 05:50:04 EST news173420426 New research from Columbia University Medical Center has illuminated a previously unknown leptin-serotonin pathway in the brain that simultaneously promotes appetite and bone mass accrual. The research, which explains how leptin - well-known appetite-suppressing hormone - acts in the brain, is published in the Sept. 4 issue of Cell. http://www.physorg.com/news171199542.html Medicine & Health Thu, 03 Sep 2009 12:40:04 EST news171199542 The team, in collaboration with University Hospital Aintree, the University of Warwick and researchers in Sweden, found that people classified as obese and those with pre-diabetes have raised levels of a protein called SPARC, that can cause tissue scarring. The research revealed that an increase in insulin, a hormone that controls blood sugar levels, and leptin, a hormone that regulates appetite, can trigger an increase in SPARC, which can prevent the proper storage of fat in fat tissue cells. http://www.physorg.com/news169375596.html Medicine & Health Thu, 13 Aug 2009 10:00:08 EST news169375596 If you are a woman who dines with a man, chances are you choose food with fewer calories than if you dine with a woman. That is one of the findings in a study conducted by researchers at McMaster University. http://www.physorg.com/news168716619.html Medicine & Health Wed, 05 Aug 2009 19:00:05 EST news168716619 As we all know from experience, people eat not only because they are hungry, but also because the food just simply tastes too good to pass up. Now, a new study in the August 6th Cell Metabolism, a Cell Press publication, helps to explain how leptin, a hormone produced by fat tissue, influences that motivation to eat. http://www.physorg.com/news168696652.html Medicine & Health Wed, 05 Aug 2009 13:11:17 EST news168696652 (PhysOrg.com) -- Eating a small lunch doesn`t necessarily mean you`ll be so hungry for dinner that you`ll eat more than usual, a new study suggests. http://www.physorg.com/news168102822.html Medicine & Health Wed, 29 Jul 2009 16:15:01 EST news168102822 Researchers at Imperial College London have identified a new appetite suppressant for promoting weight loss that they say works in rodents and may one day be used to develop an effective anti-obesity treatment. http://www.physorg.com/news163850449.html Medicine & Health Wed, 10 Jun 2009 11:50:01 EST news163850449 A new study by a Ben-Gurion University of the Negev (BGU) researcher reveals a linkage between elderly people's appetite and mortality rates, with those who report impaired appetite more likely to die sooner. http://www.physorg.com/news161365353.html Medicine & Health Tue, 12 May 2009 16:42:50 EST news161365353 Sharing a meal in good company can stimulate the appetite - particularly among hospitalized seniors - according to a new Université de Montréalstudy published in The Gerontologist. http://www.physorg.com/news160753128.html Medicine & Health Tue, 05 May 2009 14:39:12 EST news160753128 Insomnia has long been associated with poor health, including weight gain and even obesity. Now researchers at UCLA have found out why. http://www.physorg.com/news157211284.html Medicine & Health Wed, 25 Mar 2009 14:48:30 EST news157211284 A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study. Taken together, the research shows that aerobic exercise is better at suppressing appetite than non-aerobic exercise and provides a possible explanation for how that happens. http://www.physorg.com/news148192830.html Medicine & Health Thu, 11 Dec 2008 04:40:30 EST news148192830 Genetic mouse models have provided surprising insight into mechanisms linking serotoninergic compounds with the regulation of feeding behavior and body weight. The research, published by Cell Press in the November 26th issue of the journal Neuron, pinpoints a specific group of brain cells that mediate energy balance and may lead to the development of antiobesity drugs with fewer side effects. http://www.physorg.com/news146922799.html Medicine & Health Wed, 26 Nov 2008 11:53:19 EST news146922799 Researchers at Yale School of Medicine have found the brain's appetite center uses fat for fuel by involving oxygen free radicals -molecules associated with aging and neurodegeneration. The findings, reported in the journal Nature, suggest that antioxidants could play a role in weight control. http://www.physorg.com/news136641838.html Medicine & Health Wed, 30 Jul 2008 13:03:58 EST news136641838
