Stimulus-frequency otoacoustic emissions in human newborns.

Journal of the Acoustical Society of America, 2015
This study presents the first reported measurements of stimulus frequency emissions (SFOAEs) in 15 human newborns and compares their magnitudes and phase-gradient delays to those reported in adults.

Cochlear dysfunction and microvascular complications in patients with type 1 diabetes mellitus

Diabetology & Metabolic Syndrome, 2018
Sensorineural hearing impairment has been associated with DM, and it is probably linked to the same pathophysiological mechanisms as well-established in microvascular diabetes complications. The study of otoacoustic emissions (OAEs) is useful to identify

Increased contralateral suppression of otoacoustic emissions indicates a hyperresponsive medial olivocochlear system in humans with tinnitus and hyperacusis.

Journal of Neurophysiology, 2014
Atypical medial olivocochlear (MOC) feedback from brain stem to cochlea has been proposed to play a role in tinnitus, but even well-constructed tests of this idea have yielded inconsistent results. In the present study, it was hypothesized that low sound

Study on suppression of otoacoustic emissions: lateral domain Estudo da supressão da amplitude das emissões otoacústicas: dominância lateral

Brazilian Journal of Otorhinolaryngology, 2011
A pon stimulation by contralateral, ipsilateral or bilateral noise, the medial olivocochlear efferent tract changes the amplitude of otoacoustic emissions relative to the tested ear, reducing or removing it; this resulted in a reduction/suppression ...

NOX2 Contributes to High‐Frequency Outer Hair Cell Vulnerability in the Cochlea

Advanced Science, EarlyView.
This study first identifies NOX2 as a differentially expressed gene related to oxidative damage in the apical and basal turns through single‐cell RNA sequencing. NOX2 gene knockout mitigates OHCs damage caused by neomycin and noise and enhances Nrf2 expression and nuclear translocation.

Efferent inhibition of otoacoustic emissions in preterm neonates

Brazilian Journal of Otorhinolaryngology, 2015
INTRODUCTION: Abnormalities in auditory function of newborns may occur not only because of preterm birth, but also from the use of medications and from diseases related to prematurity. OBJECTIVE: To analyze the inhibitory effect from stimulation of the

Single Administration of AAV‐mAtp6v1b2 Gene Therapy Rescues Hearing and Vestibular Disorders Caused by Atp6v1b2‐Induced Lysosomal Dysfunction in Hair Cells

Advanced Science, EarlyView.
Wei et al. establish a hair cell‐specific conditional knockout mouse model (Atp6v1b2fl/fl;Atoh1Cre/+), and demonstrate the importance of Atp6v1b2 for hair cell through maintaining the survival of lysosomes. A single administration of AAV‐ie‐Eh3‐mAtp6v1b2 through scala media at P0‐P2 realizes function compensation and restores hearing and balance ...

Consequences and Mechanisms of Noise‐Induced Cochlear Synaptopathy and Hidden Hearing Loss, With Focuses on Signal Perception in Noise and Temporal Processing

Advanced Science, EarlyView.
Noise‐induced synaptopathy (NIS) is largely reversible due to self‐repair. NIS and noise‐induced hidden hearing loss are two concepts with similarities and differences. The major hearing deficits in NIHHL are temporal processing disorders. The translation of animal data in NIS studies to humans is hindered by many factors.
