Tiny molecule controls stress-induced heart disease
A tiny snippet of RNA, a chemical cousin of DNA, controls damage to the heart under several types of stress, researchers at UT Southwestern Medical Center have found. view more (2007-03-23)
Adult stem cell injections may reduce pain and improve walking in severe angina patients
Preliminary data presented on March 28 as a late-breaking abstract at the American College of Cardiology's 58th annual scientific session from the largest CD34+ adult stem cell study for heart disease has shown the first evidence that delivering a potent form of autologous (from the patient) adult stem cells into the heart muscle of patients with... view more...

Masterminding muscle development
Dr. Lizi Wu (Dana Farber Cancer Institute) and colleagues report on a critical role for one of the three mammalian mastermind genes (Maml1) in myogenesis - assigning that first biological function to the mammalian MAML Notch co-activators. view more (2006-02-28)
Heart enlargement is a common cause of sudden death in young people (p 1881)
A seminar in this week's issue of THE LANCET highlights the frequency, diagnosis and management of hypertrophic cardiomyopathy, an unexplained thickening of the heart in young adults that has a 1% annual risk of sudden death. Dr. Perry Elliott from University College, London, UK and Professor William McKenna from The Heart Hospital, London state... view more... (2004-06-02)
Vitamin D tied to muscle power in adolescent girls
Vitamin D is significantly associated with muscle power and force in adolescent girls, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2009-02-03)
Competitive athletes not over-represented in sudden cardiac death
Sudden cardiac death among young people is uncommon but is not decreasing. Three times more men than women are affected, and competitive athletes are not over-represented. This is shown a dissertation written by Aase Wisten, Ume'å University, to be publicly defended in the auditorium at Sunderby Hospital on May 25. view more (2005-05-20)
The Structural Basis of Familial Hypertrophic Cardiomyopathy is Revealed
Familial Hypertrophic Cardiomyopathy (FHC), the leading cause of sudden death in athletes and young people, is a genetic disorder of the heart that is characterized by an increased thickness in tissue of the left ventricle. view more (2007-11-12)
Novel Imaging Approach May Assist in Predicting Success of Treatment For Atrial Fibrillation
University of Utah researchers have developed a magnetic resonance imaging (MRI)-based method for detecting and quantifying injury to the wall of the heart's left atrium in patients who have undergone a procedure to treat atrial fibrillation. view more (2008-10-08)
Two treatment innovations improve heart function after heart attack
Supersaturated oxygen (SSO2) administered during catheter-based treatments for heart attack can significantly reduce heart muscle damage, according to a new study reported in Circulation: Cardiovascular Interventions, a journal of the American Heart Association. view more (2009-09-16)
Low-risk balloon trip to the heart
Patients who are at high-risk of having a heart attack or who require a bypass must undergo a coronary angiography. A new balloon catheter, being presented at the MEDTEC exhibition, allows this to be done more swiftly, more easily and with less risk than previous examinations. Calcium and cholesterol can block coronary blood vessels. The thicker... view more... (2002-03-05)
Protein's potential as a regulator of brain activity discovered
UC Irvine researchers have found that a protein best known for building connections between nerve cells and muscle also plays a role in controlling brain cell activity. view more (2006-04-21)
To regenerate muscle, cellular garbage men must become builders
For scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, what seemed like a disappointing result turned out to be an important discovery. view more (2009-09-23)
Purdue researchers find 'switch' for skeletal-muscle atrophy
Researchers in Purdue University's School of Veterinary Medicine have discovered genetic and drug-treatment methods to arrest the type of muscle atrophy often caused by muscle disuse, as well as aging and diseases such as cancer. view more (2006-05-25)
Cherry juice reduces muscle pain induced by exercise
Cherry juice can reduce muscle pain and damage induced by exercise, suggests a small study published ahead of print in the British Journal of Sports Medicine. view more (2006-06-21)
Mass. General study shows how exercise changes structure and function of heart
For the first time researchers are beginning to understand exactly how various forms of exercise impact the heart. Massachusetts General Hospital (MGH) investigators, in collaboration with the Harvard University Health Services, have found that 90 days of vigorous athletic training produces significant changes in cardiac structure and function and... view more...

First demonstration of muscle restoration in an animal model of Duchenne muscular dystrophy
Using a new type of drug that targets a specific genetic defect, researchers at the University of Pennsylvania School of Medicine, along with colleagues at PTC Therapeutics Inc. and the University of Massachusetts Medical School, have for the first time demonstrated restoration of muscle function in a mouse model of Duchenne's muscular dystrophy... view more...

Wound Healing - Discovery Of A New Therapeutic Strategy Against Hypertrophic Scarring
Wound healing appears generally a banal event, but in a certain proportion of cases it evolves inappropriately in hypertrophic scars resulting in skin and organ deformations. This is due to an excess of wound contraction, a phenomenon that generally helps to close the wound. Hypertrophic scarring is observed frequently in burned patients. For the... view more...

Scientists make breakthrough in understanding muscle contraction
Professor Susan Wray, who heads the UK's top rated Department of Physiology, and Dr. Ted Burdyga, are studying muscles in the wall of the ureter, which connects the kidney to the bladder, to understand how muscles respond to signals in the body telling them to contract or relax. view more (2005-08-01)
How to grow muscle cells in a dish
Smooth muscle cells (SMCs) are a crucial cellular component of many parts of the body, including blood vessels, the intestines, and the lungs. view more (2006-11-10)
Researchers link inflammatory diseases to increased cardiovascular risk
Patients suffering from two serious autoimmune disorders which cause muscular inflammation are at increased risk of developing cardiovascular disease. view more (2009-09-02)
