BALTIMORE, June 2 /PRNewswire/ -- One of the best post-exercise recovery drinks could already be in your refrigerator, according to new research presented at the American College of Sports Medicine conference this week. In a series of four studies, researchers found that chocolate milk offered a recovery advantage to help repair and rebuild muscles, compared to specially designed carbohydrate sports drinks. Experts agree that the two-hour window after exercise is an important, yet often...

HSP10 (Heat Shock Protein), helps monitor and organize protein interactions in the body, and responds to environmental stresses, such as exercise and infection, by increasing its production inside cells. Researchers at Liverpool, in collaboration with colleagues at the University of California, found that excessive amounts of HSP10 inside mitochondria "“ 'organs' that act as energy generators in cells "“ can halt the body's ageing process by preserving muscle strength. HSP10...

Post-meal blood vessel expansion naturally occurs in young, not old, and restoration through drug therapy could dramatically improve strength and health of elders Why do people become physically weaker as they age? And is there any way to slow, stop, or even reverse this process, breaking the link between increasing age and frailty? In a paper published online May 19 in the Journal of Clinical Endocrinology & Metabolism, University of Texas Medical Branch at Galveston researchers present...

Type 2 diabetes is a widespread problem for many people these days, and our risk for insulin resistance and diabetes only grows as we age. Now, a new report in the May issue of Cell Metabolism, a Cell Press publication, reveals a new contributor to the problem: The muscles of elderly people and of people with type 2 diabetes contain lower concentrations of a protein known as PARL (short for "presenilin-associated rhomboid-like"). PARL plays an important role within cells in remodeling...

DURHAM, N.C. "“ Humans have very limited ability to regenerate heart muscle cells, which is a key reason why heart attacks that kill cells and scar heart tissue are so dangerous. But damaged heart muscles in the amazing, highly regenerative zebrafish have given Duke University Medical Center scientists a few ideas that may lead to new directions in clinical research and better therapy after heart attacks. "Our hearts don't seem so complex that they shouldn't have the capacity to...

A new study in the Journal of Cell Biology (JCB) identifies a cytokine signaling pathway that induces the breakdown of disused skeletal muscle. Blocking this pathway could prevent immobilized patients from losing their muscle tissue. The article appears in the March 22 issue of the JCB. Skeletal muscle wastes away when its activity is reduced by, for example, a spinal cord injury. Although the mechanism by which muscle fibers break down is understood fairly well, how the process is triggered...

ANN ARBOR, Mich. -- 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. But in spite of widespread interest in these potent molecules, key details about how IGFs work on muscle cells have been lacking. Now,...

Changes in muscle cell structure can affect gene expression New findings that shed light on how genetic damage to muscle cell proteins can lead to the development of the rare muscle-wasting disease, nemaline myopathy, are reported March 15 in the Biochemical Journal. Professor Laura Machesky and colleagues from the CRUK Beatson Institute for Cancer Research in Glasgow, tested cultures of muscle cells that displayed mutations of the ACTA1 gene to determine how the mutations affected the...

A group of Marshall University researchers and their colleagues in Japan are conducting research that may lead to new ways to move or position single molecules"”a necessary step if man someday hopes to build molecular machines or other devices capable of working at very small scales. Dr. Eric Blough, a member of the research team and an associate professor in Marshall University's Department of Biological Sciences, said his group has shown how bionanomotors can be used some day to move...

A new study involving the University of Iowa, Mayo Clinic and two other institutions provides insight on weight control, suggesting that a ATP-sensitive potassium channel critical to survival and stress adaptation can contribute to fat deposition and obesity. The investigation reveals how the ATP-sensitive potassium channel in the heart and skeletal muscles affects the balance between food intake and energy used. The study, which was done in animal models, appears in the January issue of the...
