OBJECTIVES : Botulinum neurotoxin (BoNT) reduces disabling muscle contraction in numerous disorders with muscle overactivity. While motor endplates are the primary site of action for BoNT, their location is unknown in most human muscles. This study localized the motor endplate bands (MEB) within human biceps brachii (BB) muscles in relation to external(More)
Little is known about the specializations of human tongue muscles. In this study, myofibrillar adenosine triphosphatase (mATPase) histochemical staining was used to study the percentage and distribution of slow twitch muscle fibers (slow MFs) within tongue muscles of four neurologically normal human adults and specimens from a 2-year-old human, a newborn(More)
A poorly understood neural circuit in the brain stem controls swallowing. This experiment studied the swallowing circuit in the rat brain stem by means of fos immunocytochemistry. The fos protein is a marker of activated neurons, and under experimental conditions, repetition of a behavior causes the fos protein to be produced in the neurons involved in that(More)
Carcinoma of the esophagus is a disease with a poor prognosis. Surgery is considered the treatment of choice. Patients who are surgically unresectable may receive radiotherapy, plus or minus chemotherapy. While this offers reasonable palliation, a significant number of patients develop benign or malignant strictures. Frequent esophagoscopy with dilation is(More)
OBJECTIVE To introduce and assess a system for the delivery of fibroblast growth factor to autologous cartilage grafts using fibrin sealant and analyze whether this "enhancement" results in reduced rates of cartilage resorption and greater preservation of normal architectural features compared with "unenhanced" cartilage grafts. METHODS Auricular(More)
