Human ancestor Australopithecus did indeed walk upright
...pelvis is tilted in humans to give leverage to leg muscles
that extend the legs backward during bipedal striding and running. However, unlike modern humans, Australopithecines have relatively small vertebral bodies and exhibit much pathology in these vertebral bodies. This suggests that while the back part o...
UT Southwestern researchers find protein transforms sedentary muscles to resemble exercised muscles

Cells in patients noses hold potential to restore function in spinal cord injury
...o touch and proprioception (stimuli originating in muscles

Muscle derived cell transplants offer alternative incontinence therapy says Pitt study
...continence. Essentially, we are giving the bladder muscles
the ability to fix themselves by generating new muscle, said Michael Chancellor, M.D., professor of urology and gynecology at the University of Pittsburgh School of Medicine. In future studies we hope this will turn into a long lasting, if not perman...
