Comparison of healing of acute total tympanic membrane perforation between rats with and without excision of the mallear handle

Laryngoscope Investigative Otolaryngology, Volume 8, Issue 6, Page 1648-1656, December 2023., 2023
(1) The upper halves of the annulus may be the main the epithelial cell proliferation center in SD rats, the excision or preservation of the malleus handle doesn’t affect the closure of total perforation. (2) The malleus handle contributes to accelerate the perforation closure by possible guide the migration of proliferative epithelial cell.

Scientific opinion on the tolerable upper intake level for manganese

EFSA Journal, Volume 21, Issue 12, December 2023., 2023
Abstract Following a request from the European Commission (EC), the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver a scientific opinion on the tolerable upper intake level (UL) for manganese. Systematic reviews of the literature of human and animal data were conducted to assess evidence regarding excess manganese ...

Otoacoustic Emissions in Smoking and Nonsmoking Young Adults [PDF]

Clinical and Experimental Otorhinolaryngology, 2015
ObjectivesThe present study investigates the usefulness of transiently evoked otoacoustic emissions (TEOAEs) and distortion product OAEs (DPOAEs) in detecting small changes in the hearing of young smoking adults.MethodsOtoacoustic emissions were acquired

Synchronization of Spontaneous Active Motility of Hair Cell Bundles. [PDF]

PLoS ONE, 2015
Hair cells of the inner ear exhibit an active process, believed to be crucial for achieving the sensitivity of auditory and vestibular detection. One of the manifestations of the active process is the occurrence of spontaneous hair bundle oscillations in

Waves on Reissner's membrane: a mechanism for the propagation of otoacoustic emissions from the cochlea [PDF]

Cell Reports 1, 374-384 (2012), 2012
Sound is detected and converted into electrical signals within the ear. The cochlea not only acts as a passive detector of sound, however, but can also produce tones itself. These otoacoustic emissions are a striking manifestation of the cochlea's mechanical active process.

Relating the variability of tone-burst otoacoustic emission and auditory brainstem response latencies to the underlying cochlear mechanics [PDF]

, 2015
Forward and reverse cochlear latency and its relation to the frequency tuning of the auditory filters can be assessed using tone bursts (TBs). Otoacoustic emissions (TBOAEs) estimate the cochlear roundtrip time, while auditory brainstem responses (ABRs ...

Medial olivocochlear reflex effects on synchronized spontaneous otoacoustic emissions.

Journal of the Acoustical Society of America, 2020
This study characterized medial olivocochlear (MOC) reflex activity on synchronized spontaneous otoacoustic emissions (SSOAEs) as compared to transient-evoked otoacoustic emissions (TEOAEs) in normal-hearing adults.

Acquisition and Repeatability of High-Frequency Distortion Product Otoacoustic Emissions Using Two Different Calibration Methods in Newborns

Applied Sciences, 2019
Distortion-product otoacoustic emissions (DPOAEs) elicited with high-frequency (HF; up to 16 kHz) stimuli are measurable and repeatable in normal-hearing adults and children, adult patients, and are sensitive to ototoxic insults in adults.

The Auditory Nerve Overlapped Waveform (ANOW) detects small endolymphatic manipulations that may go undetected by conventional measurements [PDF]

, 2017
Electrocochleography (ECochG) has been used to assess Ménière's disease, a pathology associated with endolymphatic hydrops and low-frequency sensorineural hearing loss. However, the current ECochG techniques are limited for use at high-frequencies only (≥
