Skeletal muscle response to tenotomy.

abstract：INTRODUCTION:Muscle fiber denervation increases with age, yet studies at the tissue level are sparse due to the challenging nature of establishing the relative role of regeneration and denervation. METHODS:Muscle biopsies were obtained from the vastus lateralis of 70 healthy men (aged 72 ± 6 years; range, 65-94). Mess...
