Age-dependent bupivacaine-induced muscle toxicity during continuous peripheral nerve block in rats.

30 Oct 2009 BACKGROUND: Regional blocks improve postoperative analgesia and postoperative rehabilitation in children and adult patients. Continuous peripheral nerve blocks have been proposed as safe and effective techniques for postoperative pain relief and ... Read more...

Location of myofiber damage in skeletal muscle after lengthening contractions.

29 Sep 2009 High-force lengthening contractions are associated with muscle damage and pain, and the muscle-tendon junction is commonly cited as the primary area where myofiber damage occurs. We induced injury in the rat tibialis anterior muscle and acquired ... Read more...

DMPK protein isoforms are differentially expressed in myogenic and neural cell lineages.

29 Sep 2009 Myotonic dystrophy type 1 (DM1) is a neuromuscular disorder caused by an unstable (CTG . CAG)n segment in the 3' untranslated region of the myotonic dystrophy protein kinase (DMPK) gene. It is commonly accepted that DMPK mRNA-based toxicity is the ... Read more...

Technical information about 'Muscle Fibers, Skeletal'

Definition: Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of SKELETAL MUSCLE. They consist of MYOFIBRILS enclosed within and attached to the SARCOLEMMA. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.
