Skeletal muscles and satellite cells: How exercise leads to longer lives

A trio of researchers at Ottawa Hospital Research Institute has conducted a review of the ways that periodic activation of satellite cells through exercise can lessen senescence acquisition and myogenic decline. Satellite cell … READ MORE

FDA approves new drug to treat common form of muscular dystrophy based on research from U of A scientist

Created using synthetic DNA, viltolarsen is an excellent example of precision medicine. The U.S. FDA has approved a drug called viltolarsen to treat Duchenne muscular dystrophy. The drug was developed based on research by U of A … READ MORE

Altered composition, structure of muscles linked to stiffness, movement limits in CP children

Muscle composition and structure is altered in children with cerebral palsy — with greater amounts of collagen in the muscles’ network of proteins and sugars — making these patients more prone to stiffness and contractures that … READ MORE

How do muscle and tendon connections last a lifetime?

Cell biologists show in fruit flies how a protein controls mechanical stress on muscle-tendon attachments. Lengthwise cut through the thorax of a fruit fly having an inserted force sensor in the talin protein. The force sensor on the … READ MORE

New clues to the origin and progression of multiple sclerosis

Mapping of a certain group of cells, known as oligodendrocytes, in the central nervous system of a mouse model of multiple sclerosis (MS), shows that they might have a significant role in the development of the disease. The discovery … READ MORE

Scientists uncover why knee joint injury leads to osteoarthritis

Knee joint injuries are typically related to sports, such as football, rugby or ice hockey, but people often do not know that such injuries may lead to joint inflammation and post-traumatic osteoarthritis. OssKin Evoke University of … READ MORE

UCalgary scientists discover a new way to battle multiple sclerosis

Breakthrough for SF State kinesiologists studying metabolic protein

New technique could help improve treatment for diabetes and obesity. Assistant Professor of Kinesiology Jimmy Bagley and Irene Tobias, a postdoctoral researcher at CSU Fullerton, analyze muscle fibers. Andy Galpin CSU Fullerton By … READ MORE

Bloodless revolution in diabetes monitoring

Scientists have created a non-invasive, adhesive patch, which promises the measurement of glucose levels through the skin without a finger-prick blood test. The device can measure glucose levels without piercing the skin. University … READ MORE

Surprise finding could lead to new MS treatments

A discovery is providing hope of a new therapeutic target in Multiple Sclerosis (MS) patients that could one day be used to prevent the symptoms and progression of the disease. By removing a protein called calnexin in mice, … READ MORE

Scientists zero in on treatment for Charcot-Marie-Tooth disease

About 1 in 2,500 people have a degenerative nerve disease called Charcot-Marie-Tooth (CMT). The disease is typically diagnosed in children, who can lose their ability to walk and use their hands for fine motor skills. There is no … READ MORE

Researchers watch the knee degenerate and understand how osteoarthritis may begin

Kinesiology study shows how knee cartilage is protected by the menisci. University of Calgary researchers Ziad Abusara and Walter Herzog have discovered that most patients who had their meniscus removed developed knee osteoarthritis. … READ MORE
