OBJECTIVE To determine if exogenous neurotrophins can prevent spiral ganglion neuron degeneration in the rat cochlea. BACKGROUND The loss of hair cells resulting in sensorineural hearing loss also leads to the secondary degeneration of spiral ganglion neurons. The effectiveness of cochlear implantation in patients with profound sensorineural hearing loss(More)
Let To denote the complement of a perfect matching in the complete graph on v vertices, v even, and let cp(To) be the minimum number of cliques needed to partition the edge-set of To. We prove that cp(To)>-v for v 1> 8 and give a design characterization of the cases where equality holds. We also show that, asymptotically, cp (To) <-v log log v. 1.(More)
