In this study, we compared 2 techniques for injection of botulinum toxin type A (Botox) into the posterior cricoarytenoid (PCA) muscle for the treatment of abductor spasmodic dysphonia (ABSD). Fifteen patients with ABSD were enrolled in a prospective randomized crossover treatment trial comparing the 2 injection techniques. The PCA muscle was injected with(More)
We report an effective method of scavenging nitric oxide and nitrogen dioxide. We have compared three agents, a commercially available filter, soda lime and activated charcoal, for their effectiveness and duration of action. Complete absorption of nitric oxide and nitrogen dioxide for a period of 170 h was obtained using the commercial filter. However, soda(More)
Synchrotron-excited resonant-photoemission measurements at rare-earth 4d --> 4f and transition-metal 3p --> 3d thresholds have been carried out using a variety of complex cuprates and nickelates on stations 6.1 (grazing-incidence monochromator) and 6.2 (toroidal-grating monochromator) at the SRS CLRC Daresbury Laboratory. The systems studied are Nd(2)Ni(1 -(More)
