A research team led by Dr. Christos Mantzoros, MD, PhD, at Beth Israel Deaconess Medical Center, Harvard Medical School, has published new findings elucidating the molecular and clinical role of FNDC5/irisin in humans. http://medicalxpress.com/news/2012-10-physiological-role-hormone-fndc5irisin-revealed.html Medical research Mon, 01 Oct 2012 10:15:15 EST news268305309 You might think that the DNA you inherited is one thing that you absolutely can't do anything about, but in one sense you'd be wrong. Researchers reporting in the March issue of Cell Metabolism, a Cell Press publication, have found that when healthy but inactive men and women exercise for a matter of minutes, it produces a rather immediate change to their DNA. Perhaps even more tantalizing, the study suggests that the caffeine in your morning coffee might also influence muscle in essentially the same way. http://medicalxpress.com/news/2012-03-dna.html Genetics Tue, 06 Mar 2012 13:17:25 EST news250262231 (Medical Xpress) -- A tiny piece of RNA plays a key role in determining when muscle stem cells from mice activate and start to divide, according to researchers at the Stanford University School of Medicine. The finding may help scientists learn how to prepare human muscle stem cells for use in therapies for conditions such as muscular dystrophy and aging by controlling their activation state. http://medicalxpress.com/news/2012-02-scientists-trigger-muscle-stem-cells.html Medical research Thu, 23 Feb 2012 06:00:40 EST news249199229 Scientists at the University of Liverpool are the first to use a new laboratory technique that could reveal the causes of Chronic Fatigue Syndrome (CFS). http://medicalxpress.com/news/2011-12-reveal-chronic-fatigue-syndrome.html Medical research Thu, 22 Dec 2011 07:20:10 EST news243760801 (Medical Xpress) -- Because of its high water content and polymer network, peptide hydrogel is a promising material for protein storage and transfer without significant loss of their biological activity. These hydrogels have potential as injectable materials for medical applications, e.g., liquid injection agents that become gelatinous in the human body to keep drugs around cancerous tumors. In this study, scientists from Kansas State University, University of Nebraska, and PNNL used two native functional sequences from spider flagelliform silk protein and a trans-membrane motif of human muscle L-type calcium channel to design a self-assembling peptide, h9e. http://medicalxpress.com/news/2011-12-scientists-merge-spider-silk-human.html Medical research Fri, 02 Dec 2011 05:50:29 EST news242027414 A team of scientists from Worcester Polytechnic Institute (WPI) and CellThera, a private company located in WPI's Life Sciences and Bioengineering Center, have regenerated functional muscle tissue in mice, opening the door for a new clinical therapy to treat people who suffer major muscle trauma. http://medicalxpress.com/news/2011-11-body-rebuilding-regenerate-muscle-mice.html Medical research Tue, 29 Nov 2011 13:28:23 EST news241795693
