Stem cell injections improve spinal injuries in rats | KurzweilAI

Stem cell injections improve spinal injuries in rats | KurzweilAI | Longevity science | Scoop.it

A single injection of human neural stem cells produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury (SCI), an international team led by researchers at the University of California, San Diego School of Medicine reports.

 

Grafting neural stem cells derived from a human fetal spinal cord to the rats’ spinal injury site produced an array of therapeutic benefits — from less muscle spasticity to new connections between the injected stem cells and surviving host neurons.

New hope for sufferers of degenerative muscle disorders | KurzweilAI

New hope for sufferers of degenerative muscle disorders | KurzweilAI | Longevity science | Scoop.it

A new therapeutic technique to repair and rebuild muscle for sufferers of degenerative muscle disorders has been developed by an international team of researchers, according to a study published today in BioMed Central’s open access journal Skeletal Muscle.

 

The therapy brings together two existing techniques for muscle repair — cell transplantation (mesoangioblast stem cells) and tissue engineering, delivering the stem cells via a hydrogel cell-carrier matrix.

Light-activated skeletal muscle “blurs the boundary between nature and machines”

Light-activated skeletal muscle “blurs the boundary between nature and machines” | Longevity science | Scoop.it

MIT researchers have genetically engineered muscle cells to make them flex in response to laser light.

 

“With bio-inspired designs, biology is a metaphor, and robotics is the tool to make it happen'" says Professor Asada. "With bio-integrated designs, biology provides the materials, not just the metaphor. This is a new direction we’re pushing in biorobotics.”

Exercise as good as massage for sore muscles

Exercise as good as massage for sore muscles | Longevity science | Scoop.it

The aches and pains people suffer after working out more than usual can be relieved just as well by exercise as by massage, according to a new study.

"It's a common belief that massage is better, but it isn't better. Massage and exercise had the same benefits," said Lars Andersen, the lead author of the study and a professor at the National Research Center for the Working Environment in Copenhagen.

Fish oils 'help slow age decline'

Fish oils 'help slow age decline' | Longevity science | Scoop.it
Moderate exercise, and a regular intake of oily fish fatty acids, keeps elderly immobility at bay.

 

A small study of women found that omega-3 fatty acids plus exercise increased muscle strength by 20%, almost twice as much as when olive oil was used.

 

Exercise combats the natural muscle loss associated with aging. Maintaining adequate protein intake and staying active are already known to mitigate the rate of degeneration. It now appears that adding omega-3s could significantly boost this effect.

 

A larger study is planned, including men and women.

"Exercise" shown to improve the performance of lab-grown muscle implants

"Exercise" shown to improve the performance of lab-grown muscle implants | Longevity science | Scoop.it

We all know that you need to exercise if you want to develop your muscles. As it turns out, however, exercise also makes lab-grown muscle implants more effective when introduced to the body.
