Mitochondrial Dysfunction, Nutrition and Aging

By Ward Dean, MD Every cell in the human body is packed with tiny organelles called mitochondria (Fig. 1). Mitochondria are often referred to as...

New Key To Tissue Regeneration: Drug Treatment Triggers Sodium Ions To...

Sodium gets a bad rap for contributing to hypertension and cardiovascular disease. Now biologists at Tufts University's School of Arts and Sciences have discovered that sodium also plays a key role in initiating a regenerative response after severe injury. The Tufts scientists have found a way to regenerate injured spinal cord and muscle by using small molecule drugs to trigger an influx of sodium ions into injured cells.

New Study: Tart Cherries Reduce Uric Acid Levels (Gout) and C-Reactive...

Tart cherries have long been researched for their association with pain relief – ranging from gout and arthritis joint pain to exercise-related muscle pain....

Gene Therapy Helps Weak Mice Grow Strong, May Benefit ALS and...

A virus that shuttles a therapeutic gene into cells may one day help people with a range disorders, from muscular dystrophy to amyotrophic lateral...

Researchers Identify Gene Implicated in Statin Muscle Pains, Discomfort

Researchers have used a novel approach to identify a genetic variant that may contribute to the muscle pain and weakness experienced by some statin...

Muscle And Bone Diseases Affect Each Other, According To New Theory

Traditionally, doctors and clinicians thought diseases that affect muscles or bones affected those areas specifically. For example, bone diseases only affect bones, or muscle diseases only concerned muscles. But recent evidence supports the notion that...

Wireless Device Helps Athletes Get The Most Out Of Exercise

New research at the University of Essex could help athletes train to their maximum potential without putting undue pressure on their muscles. A special wireless device -- called the iSense -- has been devised which is capable of predicting and detecting the status of muscles during training and can be adapted to any sport.

Light Weights Are Just As Good For Building Muscle, Getting Stronger,...

Lifting less weight more times is just as effective at building muscle as training with heavy weights, a finding by McMaster researchers that turns conventional wisdom on its head. The key to muscle gain, say the researchers, is working to the point of fatigue.

Clenching Left Hand Could Help Athletes Avoid Choking Under Pressure

Some athletes may improve their performance under pressure simply by squeezing a ball or clenching their left hand before competition to activate certain parts of the brain, according to new research published by the American Psychological Association.

Training One Arm Improves Strength, Decreases Muscle Loss in Opposite Arm

New research from Edith Cowan University (ECU) has revealed that training one arm can improve strength and decrease muscle loss in the other arm...

Acupuncture’s Molecular Effects Pinned Down

Scientists have taken another important step toward understanding just how sticking needles into the body can ease pain. In a paper published online May 30 in Nature Neuroscience, a team at the University of Rochester Medical Center identifies the molecule adenosine as a central player in parlaying some of the effects of acupuncture in the body.

Cherry Juice May Prevent Muscle Damage Pain

The familiar "no pain, no gain" phrase usually associated with exercise may be a thing of the past if results from a study on cherry juice published in the online version of the British Journal of Sports Medicine prove true in future research. Historically, a number of approaches to prevent exercise-induced muscle pain and damage have been examined, but few have been effective. Declan Connolly, associate professor of education and director of the human performance laboratory at the...
