A number of autosomal recessive syndromes feature both sensorineural hearing loss and retinal degeneration. The mouse mutant tubby also combines hearing loss with progressive retinal degeneration, and thus may constitute a useful model of one form of human sensorineural deafness/retinal dystrophic syndrome. It has not been directly demonstrated that the(More)
Mice homozygous for a defect of the tub (rd5) gene exhibit cochlear and retinal degeneration combined with obesity, and resemble certain human autosomal recessive sensory deficit syndromes. To establish the progressive nature of sensory cell loss associated with the tub gene, and to differentiate tub-related losses from those associated with the C57(More)
We implanted keratin and poly(methyl methacrylate) (PMMA) particles to the surface of mouse calvariae to produce a quantitative, localized, inflammatory bone remodeling similar to that seen in cholesteatoma. Both types of particles resulted in increased osteoclast density compared with controls. Osteoclasts infiltrated from marrow and vascular spaces and(More)
Some genetic syndromes causing loss of hearing and vision, such as some forms of Usher’s syndrome, also cause reduced sperm cell motility, bronchiectasis, and other pathologies involving cilia- and flagella-bearing cells. In some Usher’s patients, ultrastructural defects of axonemes within photoreceptor ciliary bridges, nasal cilia, and sperm cell flagella(More)
A previous study of C70 in deuterated chlorobenzene generated evidence suggesting C70 was experiencing unique reorientational behavior at given temperatures. The present study explores the possibility that this behavior is present across other solvents. The 13C spin-lattice relaxation rates for four carbon resonances in C70 were analyzed in benzene-d6,(More)
The deafness mouse (dn/dn) is a well known model of hereditary deafness uncomplicated by behavioral and motor disturbances. The organ of Corti in this mouse develops a normal complement of sensory and supporting cell structures, yet animals homozygous for this gene never demonstrate any hearing capacity. They are profoundly deaf from birth. Soon after(More)
