Lacking a single protein speeds up mice muscular aging

One alteration that affects old people’s quality of life is muscular aging, provoking loss of strength, known as sarcopenia. Aged 55, people ...

Cause of heart arrhythmia in adult muscular dystrophy clarified

An international joint research team including Professor TAKAHASHI Masanori (Graduate School of Medicine, Osaka University) discovered that the cause of heart arrhythmia ...

Discovery of molecular protection linked to a degenerative neuromuscular disease

Kennedy’s disease leads to progressive muscle wastage. It is a condition that affects only men and it appears between 40 and 50 years of age. There is no specific treatment available. In individuals with this disease, muscle cells and motor neurons die over the years because they accumulate a protein that is mutated. Researchers at IRB Barcelona discover that this protein has a self-protective mechanism through which the deleterious effects of the mutation are delayed. ... Full story

Study finds one-third of women taking bisphosphonates remain at risk for fracture

INDIANAPOLIS -- More than 53 million Americans age 50 and older, primarily women, have osteoporosis or are at high risk for the condition due to low bone density. A recent study of oral bisphosphonates, the most commonly prescribed osteoporosis treatment, found that approximately a third of women prescribed these drugs continue to be at elevated risk for bone fracture, an outcome that may have several origins. ...

Disrupted spinal fluid flow could cause scoliosis, new zebrafish study says

New research suggests that idiopathic scoliosis, a debilitating disease characterized by a three-dimensional curvature of the spine, could be caused by irregularities in the flow of fluid in the spinal column. ... Full story

The ancient Chinese martial art is a cheap, effective treatment for knee pain, says a new study by Tufts professor ... Full story

New insights into muscular dystrophy point to potential treatment avenues

The average healthy man is 54 percent muscle by mass, but people with muscular dystrophy, an incurable, genetic condition, have almost no muscle at terminal stages of the disease. New research from The Rockefeller University provides insights about what causes patients’ muscles to degenerate and offers potential avenues for drug development. ... Full story

Intensive aquatic resistance training promotes cartilage health and quality in knee osteoarthritis

Postmenopausal women with mild knee osteoarthritis, who may avoid strenuous exercise due to pain, can safely promote cartilage health and improve aerobic fitness with intensive aquatic resistance training. ... Full story

Hip arthritis and muscle wastage

La Trobe University researchers have discovered people with hip osteoarthritis suffer from shrinkage of a special group of deep gluteal muscle, graphically documenting this by MRI (magnetic resonance imaging) scans. ... Full story
