Sex influences diaphragm muscle response in exercised mdx mice.

Physical exercise promotes increased muscle damage in the mdx mice, the experimental model of Duchenne muscular dystrophy. Studies suggest that the estrogen level in females makes them less susceptible to muscle injuries. The aim of this study was to characterize the diaphragm (DIA) muscle response to physical exercise in male and female mdx mice.

Muscle and nerve responses after different intervals of electrical stimulation sessions on denervated rat muscle.

Objective: Electrical stimulation is a procedure used to treat denervated muscles. The number of electrical stimulation sessions varies across muscle rehabilitation protocols, from daily to certain days throughout the week. The purpose of this study was to evaluate how muscle and nerve respond to different intervals of electrical stimulation applied to denervated muscle.

Primary nerve repair by muscle autografts prepared with local anesthetic.

We evaluated the usefulness of muscle autografts obtained immediately after graft preparation with lidocaine injections for primary nerve repair. The right sciatic nerve of adult Wistar rats was sectioned, and muscle grafts obtained 15 min or 24 h after lidocaine injection were used to repair a gap 1.5 cm long.
