Details of the work are published in two complementary studies published in the September online issues of the journals Experimental Cell Research and Stem Cell Research. http://phys.org/news269279846.html Biology Fri, 12 Oct 2012 16:57:36 EST news269279846 Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient's own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow. Bioengineers can already make 2D structures out of many kinds of tissue, but one of the major roadblocks to making the jump to 3D is keeping the cells within large structures from suffocating; organs have complicated 3D blood vessel networks that are still impossible to recreate in the laboratory. http://phys.org/news260357139.html Chemistry Sun, 01 Jul 2012 13:00:04 EST news260357139 (PhysOrg.com) -- Most primitive known vertebrate and therefore the ancestor of all descendant vertebrates, including humans, discovered. http://phys.org/news250189687.html Other Sciences Mon, 05 Mar 2012 17:08:29 EST news250189687 Researchers from The University of Nottingham have demonstrated how a species of flatworm overcomes the ageing process to be potentially immortal. http://phys.org/news249573172.html Biology Mon, 27 Feb 2012 15:00:01 EST news249573172 The world's first "test-tube" meat, a hamburger made from a cow's stem cells, will be produced this fall, Dutch scientist Mark Post told a major science conference on Sunday. http://phys.org/news248936854.html Biology Mon, 20 Feb 2012 05:07:44 EST news248936854 Researchers at the University of California, Berkeley, have turned back the clock on mature muscle tissue, coaxing it back to an earlier stem cell stage to form new muscle. Moreover, they showed in mice that the newly reprogrammed muscle stem cells could be used to help repair damaged tissue. http://phys.org/news235912558.html Biology Thu, 22 Sep 2011 12:20:47 EST news235912558 The package on a supermarket steak may say "grass-fed" or "grass-finished," but how can a consumer know whether the cow spent its days grazing peacefully on meadow grass or actually gorged on feedlot corn? In ACS's Journal of Agricultural and Food Chemistry, scientists are now reporting the development of a method that can reconstruct the dietary history of cattle and authenticate the origins of beef. http://phys.org/news224328914.html Chemistry Wed, 11 May 2011 10:35:39 EST news224328914 (PhysOrg.com) -- An innovative strategy for regenerating skeletal muscle tissue using cells from the recipient’s own body is outlined in UCL research published today. http://phys.org/news220884718.html Medicine & Health Fri, 01 Apr 2011 13:52:09 EST news220884718 Scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ), jointly with colleagues in the United States, have found out that inflammations of the heart muscle are caused by attacks of a specific type of immune cells. These immune cells attack the body's own tissue because during their maturation they did not have the chance to develop tolerance against a protein that is only found in the heart muscle. http://phys.org/news220610590.html Medicine & Health Tue, 29 Mar 2011 09:43:27 EST news220610590 Nanoscale whiskers from sea creatures could grow human muscle tissue http://phys.org/news219069843.html Nanotechnology Fri, 11 Mar 2011 12:44:18 EST news219069843 Mammoths, which went extinct about 10,000 years ago, may once again walk the Earth. http://phys.org/news214406296.html Biology Sun, 16 Jan 2011 13:18:30 EST news214406296 Daniel Kelly, M.D., and his colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) at Lake Nona have unveiled a surprising new model for studying muscle function: the couch potato mouse. While these mice maintain normal activity and body weight, they do not have the energy to exercise. In the December 1 issue of Cell Metabolism, Dr. Kelly's team reports what happens when muscle tissue lacks PGC-1, a protein coactivator that muscles need to convert fuel into energy. http://phys.org/news210346745.html Medicine & Health Tue, 30 Nov 2010 13:39:23 EST news210346745 A new research study published in The FASEB Journal may change how sports injuries involving muscle tissue are treated, as well as how much patient monitoring is necessary when potent anti-inflammatory drugs are prescribed for a long time. That's because the study shows for the first time that inflammation actually helps to heal damaged muscle tissue, turning conventional wisdom on its head that inflammation must be largely controlled to encourage healing. http://phys.org/news205413451.html Medicine & Health Mon, 04 Oct 2010 12:17:45 EST news205413451 Garlic has "significant" potential for preventing cardiomyopathy, a form of heart disease that is a leading cause of death in people with diabetes, scientists have concluded in a new study. Their report, which also explains why people with diabetes are at high risk for diabetic cardiomyopathy, appears in ACS' bi-weekly Journal of Agricultural and Food Chemistry. http://phys.org/news204972652.html Chemistry Wed, 29 Sep 2010 09:52:08 EST news204972652 When muscle tissue experiences trauma or disease, such as muscular dystrophy, stem cells in the muscle known as "satellite cells" respond to repair and regenerate the muscle. These cells are particularly important in neuromuscular diseases, such as muscular dystrophy, which affect muscle stability and repair. Now, University of Missouri researchers have used time-lapse photography to document satellite cell movements and behaviors when they interact with their 'host' myofiber. Scientists hope that if they can understand more about what satellite cells do in healthy muscle, obstacles to cell or gene therapies for muscular dystrophy might be overcome. http://phys.org/news192368238.html Medicine & Health Thu, 06 May 2010 12:37:34 EST news192368238 New research shows how a mutation causes a common inherited neurodegenerative disease, according to a study in the March 24 issue of The Journal of Neuroscience. The study shows that the mutation of a specific protein known to cause Charcot-Marie-Tooth (CMT) disrupts the movement of mitochondria, the energy-supplying machines inside each cell. The regulated movement of mitochondria along nerve cell fibers is vital to normal communication between the brain and muscles. http://phys.org/news188588581.html Medicine & Health Tue, 23 Mar 2010 18:43:44 EST news188588581 The muscle-building abilities of hormones known as insulin-like growth factors (IGFs) are legendary. Just do an online search and you'll find not only scientific papers discussing the effects of IGFs on the cells that give rise to muscle tissue, but also scores of ads touting the purported benefits of IGF supplements for bodybuilding. http://phys.org/news187895015.html Medicine & Health Mon, 15 Mar 2010 18:04:48 EST news187895015 Researchers reporting in the February 3rd issue of Cell Metabolism may have a new way to trick the body into consuming more energy. The target in this case is an enzyme that indirectly controls the activity of what the researchers refer to as the "energy master switch." It boils down to this: When you give mice a chemical that blocks the function of the enzyme known as Fyn kinase, they almost immediately begin burning more fat. http://phys.org/news184344941.html Medicine & Health Tue, 02 Feb 2010 15:10:01 EST news184344941 Researchers at the Indiana University and Stanford University schools of medicine have determined how a "chemical chaperone" does its job in the body, which could lead to a new class of drugs to help reduce the muscle damage caused by heart attacks. http://phys.org/news182326944.html Chemistry Sun, 10 Jan 2010 13:00:01 EST news182326944 When muscle cells need repair, they use odor-detecting tools found in the nose to start the process, researchers have discovered. http://phys.org/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://phys.org/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://phys.org/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://phys.org/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://phys.org/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://phys.org/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://phys.org/news168010187.html Medicine & Health Tue, 28 Jul 2009 14:30:36 EST news168010187 Arvelle White lifts weights three or four times a week.
