Many people have traded in their gas-guzzling old "clunkers" for newer and more efficient models or cut back on energy use at home by opting for Energy Star appliances and compact fluorescent light bulbs. But, when it comes to our muscles, a little less efficiency might be just what the doctor ordered, suggests a report in the January Cell Metabolism, a Cell Press publication. The researchers from the Mayo Clinic and the University of Iowa have new insight into an important "fuel gauge" in...

New research in the FASEB Journal shows free radicals damage mitochondria in our muscle cells, resulting in age-related muscle loss If you're an aging baby boomer hoping for a buffer physique, there's hope. A team of American scientists from Texas and Michigan have made a significant discovery about the cause of age-related muscle atrophy that could lead to new drugs to halt this natural process. This research, available online the FASEB Journal (http://www.fasebj.org), shows that free...

In order to maintain muscle strength with age, cells must rid themselves of the garbage that accumulates in them over time, just as it does in any household, according to a new study in the December issue of Cell Metabolism, a Cell Press journal. In the case of cells, that waste material includes spent organelles, toxic clumps of proteins, and pathogens. The researchers made their discovery by studying mice that were deficient for a gene required for the tightly controlled process of...

Study finds physiological changes in one muscle help ease pain Strength training exercises using dumbbells can reduce pain and improve function in the trapezius muscle, the large muscle which extends from the back of the head, down the neck and into the upper back. The exercises also improve the muscle's ability to respond quickly and forcefully among women suffering trapezius myalgia, a tenderness and tightness in the upper trapezius muscle. The results are the latest findings from an...

When muscle cells need repair, they use odor-detecting tools found in the nose to start the process, researchers have discovered. The results are published online and scheduled for publication in the November issue of the journal Developmental Cell. Found on the surfaces of neurons inside the nose, odorant receptors are molecules that bind and respond to substances wafting through the air. Researchers have shown that one particular odorant receptor gene, MOR23, is turned on in muscle cells...

Skeletal muscle plays a critical role in regulating blood sugar levels in the body. But few studies have comprehensively examined how obesity caused by a high-fat diet affects the health of muscle in adolescents who are pre-diabetic. In a paper published Oct. 6 in the scientific journal PLoS One, a team of McMaster University researchers report that the health of young adult muscle declines during the pre-diabetic state, which is when blood sugar levels are higher than normal but lower than...

Recent studies conducted by Dr. Eric Blough and his colleagues at Marshall University have shown that use of the common pain reliever acetaminophen may help prevent age-associated muscle loss and other conditions. Their study examined how acetaminophen may affect the regulation of protein kinase B (Akt), an enzyme known to play an important role in regulation of cellular survival, proliferation and metabolism. The researchers' data indicates that aging skeletal muscles experience a decrease...

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. Their findings, published online this week in the journal Proceedings of the National Academy of Sciences (PNAS), provide conclusive proof that, when a muscle is injured, white blood cells called macrophages play a crucial role in its regeneration. The scientists also uncovered the genetic switch that controls this process,...

Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs "” even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes. Now Johns Hopkins scientists, working with the simplest of organisms, have discovered the molecular sensor that lets cells not only "feel" changes to their neat shapes, but also to remodel themselves back...

New research with transgenic mice reveals that a therapy directed at the muscle significantly improves disease symptoms of a genetic disorder characterized by destruction of the neurons that control movement. The study, published by Cell Press in the August 13th issue of the journal Neuron, highlights a promising new treatment for this currently incurable and nontreatable neurodegenerative disorder.Spinal and bulbar muscular atrophy (SBMA), or Kennedy's disease, is a neurodegenerative disease...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
