When muscle cells need repair, they use odor-detecting tools found in the nose to start the process, researchers have discovered. http://www.physorg.com/news177598122.html Biology Mon, 16 Nov 2009 12:49:29 EST news177598122 (PhysOrg.com) -- Scientists have extracted organically preserved muscle tissue from an 18 million years old salamander fossil. The discovery by researchers from University College Dublin, the UK and Spain, reported in the Proceedings of the Royal Society B shows that soft tissue can be preserved under a broader set of fossil conditions than previously known. http://www.physorg.com/news176660912.html Other Sciences Thu, 05 Nov 2009 17:20:01 EST news176660912 University of Washington (UW) researchers have succeeded in engineering human tissue patches free of some problems that have stymied stem-cell repair for damaged hearts. http://www.physorg.com/news174139339.html Medicine & Health Wed, 07 Oct 2009 13:02:58 EST news174139339 If you think the air outside is polluted, a new research report in the September 2009 issue of the journal Genetics might make you to think twice about the air inside our bodies too. That's because researchers show how about 3 percent of the air we breathe gets converted into harmful superoxides, which ultimately harm our muscles. Specifically, these superoxides lead to the creation of a toxic molecule called "reactive oxygen species" or ROS, which is shown to be particularly harmful to muscle tissue, and may lead to problems ranging from aging and frailty to Parkinson's disease and cancer. http://www.physorg.com/news172842389.html Medicine & Health Tue, 22 Sep 2009 13:10:01 EST news172842389 A team of researchers led by Massachusetts General Hospital (MGH) radiologists has developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas of myocardial ischemia - restricted blood flow to heart muscle tissue - giving a better indication of clinically significant coronary artery disease. Their report appears in the September 15 issue of the Journal of the American College of Cardiology. http://www.physorg.com/news172230356.html Medicine & Health Tue, 15 Sep 2009 11:00:02 EST news172230356 Patients suffering from two serious autoimmune disorders which cause muscular inflammation are at increased risk of developing cardiovascular disease, says a group of Montreal researchers. Dr. Christian A. Pineau and his team at the Research Institute of the McGill University Health Centre (RI-MUHC) have linked muscular inflammation to increased cardiovascular risk for the first time. Their results were published recently in The Journal of Rheumatology. http://www.physorg.com/news171031498.html Medicine & Health Tue, 01 Sep 2009 13:46:00 EST news171031498 Being active at age 5 helps kids stay lean as they age even if they don't remain as active later in childhood, a new University of Iowa study shows. http://www.physorg.com/news168010187.html Medicine & Health Tue, 28 Jul 2009 14:30:36 EST news168010187 Arvelle White lifts weights three or four times a week. Before he even looks at a dumbbell, though, he hops on a treadmill and runs for 20 minutes. http://www.physorg.com/news166121437.html Medicine & Health Mon, 06 Jul 2009 23:50:01 EST news166121437 Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa have discovered a powerful new way to stimulate muscle regeneration, paving the way for new treatments for debilitating conditions such as muscular dystrophy. http://www.physorg.com/news163343157.html Medicine & Health Thu, 04 Jun 2009 14:06:21 EST news163343157 (PhysOrg.com) -- Researchers at the Hospital for Sick Children (SickKids) and the University of Toronto have found a gene that plays a crucial role in the development of rhabdomyosarcoma - the most common childhood sarcoma (soft tissue cancer). The gene is called integrin-linked kinase (ILK) and is unique in that it can act as both a tumour suppressor and a tumour promoter. The study is published in the June issue of The Journal of Clinical Investigation. http://www.physorg.com/news162655843.html Medicine & Health Wed, 27 May 2009 15:11:19 EST news162655843 Researchers at the University of Minnesota Medical School have discovered a new therapy that shows potential to treat people with Duchenne muscular dystrophy, a fatal disease and the most common form of muscular dystrophy in children. http://www.physorg.com/news162569608.html Medicine & Health Tue, 26 May 2009 15:15:29 EST news162569608 A new drug-free treatment for asthma has been shown to be effective in an international study of patients with severe, uncontrolled asthma. The results showed statistically significant improvements in quality of life and reductions in asthma attacks and emergency room visits for patients who underwent the treatment. http://www.physorg.com/news161884467.html Medicine & Health Mon, 18 May 2009 16:55:02 EST news161884467 A potential vaccine for Alzheimer's disease also has been shown in mice to slow the weakening of muscles associated with inclusion body myositis, a disorder that affects the elderly. http://www.physorg.com/news161439371.html Medicine & Health Wed, 13 May 2009 13:16:42 EST news161439371 In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers -including 2007 Nobel Prize winner Mario R. Capecchi -have created a "switch" that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. http://www.physorg.com/news157655456.html Medicine & Health Mon, 30 Mar 2009 18:11:53 EST news157655456 Genetic researchers at Children's National Medical Center and the National Center of Neurology and Psychiatry in Tokyo published the results of the first successful application of "multiple exon-skipping" to curb the devastating effects of Duchenne muscular dystrophy in an animal larger than a mouse. Multiple exon-skipping employs multiple DNA-like molecules as a "DNA band-aids" to skip over the parts of the mutated gene that block the effective creation of proteins. http://www.physorg.com/news156435829.html Medicine & Health Mon, 16 Mar 2009 15:25:36 EST news156435829 A University of Colorado at Boulder research team has identified a type of skeletal muscle stem cell that contributes to the repair of damaged muscles in mice, which could have important implications in the treatment of injured, diseased or aging muscle tissue in humans, including the ravages of muscular dystrophy. http://www.physorg.com/news155482971.html Biology Thu, 05 Mar 2009 13:43:26 EST news155482971 Researchers at the University of Pennsylvania School of Medicine and the University of Connecticut have pinpointed the source of immature cells that spur misplaced bone growth. Unexpectedly, the major repository of bone-forming cells originates in blood vessels deep within skeletal muscle and other connective tissues, not from muscle stem cells themselves. The work also shows that cells important in the inflammatory response to injury trigger skeleton-stimulating proteins to transform muscle tissue into bone. http://www.physorg.com/news155315646.html Medicine & Health Tue, 03 Mar 2009 15:14:38 EST news155315646 The key to good health is to be physically active. The key to being active is… to be born that way? The well-documented importance of exercise in maintaining fitness has created the idea that individuals can manage their health by increasing their activity. But what if the inclination to engage in physical activity is itself significantly affected by factors that are predetermined? Two new studies suggest that the inclination to exercise may be strongly affected by genetics. http://www.physorg.com/news135435854.html Medicine & Health Wed, 16 Jul 2008 14:04:14 EST news135435854
