Insights Into Elevated Distortion Product Otoacoustic Emissions In Sickle Cell Disease: Comparisons of Hydroxyurea-treated and Non-treated Young Children
(East Carolina University, 2006)
Distortion product otoacoustic emissions (DPOAEs) were examined in 15 normal- hearing African-American children between the ages of 6 and 14 years with homozygous sickle cell disease (SCD), who were on a regimen of hydroxyurea ...
A comparison of vestibular and auditory phenotypes in inbred mouse strains
(East Carolina University, 2006-05-26)
The purposes of this research were to quantify gravity receptor function in inbred mouse strains and compare vestibular and auditory function for strain- and age-matched animals. Vestibular evoked potentials (VsEPs) were ...
A targeted Coch missense mutation: a knock-in mouse model for DFNA9 late-onset hearing loss and vestibular dysfunction
(East Carolina University, 2008-11-01)
Mutations in COCH (coagulation factor C homology) are etiologic for the late-onset, progressive, sensorineural hearing loss and vestibular dysfunction known as DFNA9. We introduced the G88E mutation by gene targeting into ...
Otoconin-90 Deletion Leads to Imbalance but Normal Hearing: A Comparison with Other Otoconia Mutants
(East Carolina University, 2008-04)
Our sense of gravitation and linear acceleration is mediated by stimulation of vestibular hair cells through displacement of otoconia in the utricle and saccule (the gravity receptor organ). We recently showed that otoconin-90 ...
Orphan Glutamate Receptor delta-1 Subunit Required for High-Frequency Hearing
(East Carolina University, 2007-06)
The function of the orphan glutamate receptor delta subunits (GluR 1 and GluR 2) remains unclear. GluR 2 is expressed exclusively in the Purkinje cells of the cerebellum, and GluR 1 is prominently expressed in inner ear ...
A Quantitative Survey of Gravity Receptor Function in Mutant Mouse Strains
(East Carolina University, 2005-12)
The purpose of this research was to identify vestibular deficits in mice using linear vestibular evoked potentials (VsEPs). VsEP thresholds, peak latencies, and peak amplitudes from 24 strains with known genetic mutations ...
Characterization of Vestibular Dysfunction in the Mouse Model for Usher Syndrome 1F
(East Carolina University, 2005-06)
The deaf-circling Ames waltzer (av) mouse harbors a mutation in the protocadherin 15 (Pcdh15) gene and is a model for inner ear defects associated with Usher syndrome type 1F. Earlier studies showed altered cochlear hair ...
