Hereditary canine spinal muscular atrophy (HCSMA) features rapidly progressive muscle weakness that affects muscles in an apparent proximal-to-distal gradient. In the medial gastrocnemius (MG) muscle of homozygous HCSMA animals, motor unit tetanic failure is apparent before the appearance of muscle weakness and appears to be presynaptic in origin. We(More)
Two hundred forty-six African American adolescents were randomly assigned to an educational program or an 8-week intervention that combined education with behavior skills training including correct condom use, sexual assertion, refusal, information provision, self-management, problem solving, and risk recognition.

Progressive visual reaction times were measured before and after exposure of 10 subjects (anaesthetics or anaesthetic technicians) to either halothane 100-150 p.p.m. in air or air alone. There were no significant differences between the control and test situations. In a subsequent study of 15 psychology students using an audiovisual reaction time test, a(More)
Recovery from anaesthesia with Althesin, nitrous oxide, oxygen and halothane was assessed in 29 female patients undergoing minor gynaecological surgery using an audiovisual reaction time test. A further 29 female patients not undergoing anaesthesia or surgery were subjected to the audiovisual reaction time test at similar time intervals as the anaesthetised(More)
