Biocompatibility of Liposome Nanocarriers in the Rat Inner Ear After Intratympanic Administration

open access: yesNanoscale Research Letters, 2017
Liposome nanocarriers (LPNs) are potentially the future of inner ear therapy due to their high drug loading capacity and efficient uptake in the inner ear after a minimally invasive intratympanic administration.

Potential application value of pigment epithelium-derived factor in sensorineural hearing loss

open access: yesFrontiers in Neuroscience, 2023
The inner ear is a complex and precise auditory perception system responsible for receiving and converting sound signals into neural signals, enabling us to perceive and understand sound.

Optimization of a Fixed Virtual Sensing Feedback ANC Controller for In-Ear Headphones with Multiple Loudspeakers [PDF]

open access: yesarXiv, 2021
In this paper we consider an in-ear headphone equipped with an inner microphone and multiple loudspeakers and we propose an optimization procedure with a convex objective function to derive a fixed multi-loudspeaker ANC controller aiming at minimizing the sound pressure at the ear drum.

The tip-link antigen, a protein associated with the transduction complex of sensory hair cells, is protocadherin-15 [PDF]

open access: yes, 2006
Sound and acceleration are detected by hair bundles, mechanosensory structures located at the apical pole of hair cells in the inner ear. The different elements of the hair bundle, the stereocilia and a kinocilium, are interconnected by a variety of link

Visualization of macrophage subsets in the development of the fetal human inner ear

open access: yesFrontiers in Immunology, 2022
BackgroundHuman inner ear contains macrophages whose functional role in early development is yet unclear. Recent studies describe inner ear macrophages act as effector cells of the innate immune system and are often activated following acoustic trauma or

The physics of hearing: fluid mechanics and the active process of the inner ear [PDF]

open access: yesRep. Progr. Phys. 77:7 (2014), 2014
Most sounds of interest consist of complex, time-dependent admixtures of tones of diverse frequencies and variable amplitudes. To detect and process these signals, the ear employs a highly nonlinear, adaptive, real-time spectral analyzer: the cochlea.

Electrogenic transport and K(+) ion channel expression by the human endolymphatic sac epithelium. [PDF]

open access: yes, 2015
The endolymphatic sac (ES) is a cystic organ that is a part of the inner ear and is connected to the cochlea and vestibule. The ES is thought to be involved in inner ear ion homeostasis and fluid volume regulation for the maintenance of hearing and ...

Manufacturing and in vivo inner ear visualization of MRI traceable liposome nanoparticles encapsulating gadolinium

open access: yesJournal of Nanobiotechnology, 2010
Background Treatment of inner ear diseases remains a problem because of limited passage through the blood-inner ear barriers and lack of control with the delivery of treatment agents by intravenous or oral administration. As a minimally-invasive approach,
