Biomaterial-based drug delivery systems in the treatment of inner ear disorders [PDF]

Journal of Nanobiotechnology
Inner ear disorders are among the predominant etiology of hearing loss. The blood-labyrinth barrier limits the ability of drugs to attain pharmacologically effective concentrations within the inner ear; consequently, delivering drugs systemically is ...

Dual contribution to amplification in the mammalian inner ear [PDF]

Phys. Rev. Lett. 105, 118102 (2010), 2010
The inner ear achieves a wide dynamic range of responsiveness by mechanically amplifying weak sounds. The enormous mechanical gain reported for the mammalian cochlea, which exceeds a factor of 4,000, poses a challenge for theory. Here we show how such a large gain can result from an interaction between amplification by low-gain hair bundles and a ...

The Blood-Labyrinth Barrier: Non-Invasive Delivery Strategies for Inner Ear Drug Delivery [PDF]

Pharmaceutics
The inner ear is a relatively isolated organ, protected by the blood-labyrinth barrier (BLB). This barrier creates a unique lymphatic fluid environment within the inner ear, maintaining a stable physiological state essential for the mechano-electrical ...

Defective Tmprss3-Associated Hair Cell Degeneration in Inner Ear Organoids [PDF]

Stem Cell Reports, 2019
Summary: Mutations in the gene encoding the type II transmembrane protease 3 (TMPRSS3) cause human hearing loss, although the underlying mechanisms that result in TMPRSS3-related hearing loss are still unclear.

Knockout of dhx38 Causes Inner Ear Developmental Defects in Zebrafish [PDF]

Biomedicines
Background: Alternative splicing is essential for the physiological and pathological development of the inner ear. Disruptions in this process can result in both syndromic and non-syndromic forms of hearing loss.

Refining surgical techniques for efficient posterior semicircular canal gene delivery in the adult mammalian inner ear with minimal hearing loss

Scientific Reports, 2021
Hearing loss is a common disability affecting the world’s population today. While several studies have shown that inner ear gene therapy can be successfully applied to mouse models of hereditary hearing loss to improve hearing, most of these studies rely

Fzd3 Expression Within Inner Ear Afferent Neurons Is Necessary for Central Pathfinding

Frontiers in Neuroscience, 2022
During development the afferent neurons of the inner ear make precise wiring decisions in the hindbrain reflective of their topographic distribution in the periphery.

Nanocarriers for Inner Ear Disease Therapy

Frontiers in Cellular Neuroscience, 2021
Hearing loss is a common disease due to sensory loss caused by the diseases in the inner ear. The development of delivery systems for inner ear disease therapy is important to achieve high efficiency and reduce side effects.

Inner ear malformation

Listy klinicke logopedie, 2020
Inner ear malformation comprises a broad group of disorders, the main symptom of which is hearing loss. The disorder occurs during the embryonic development of the auditory system. Only about 20 % of malformations can be diagnosed radiologically. Hearing

A Toy Model for the Auditory System that exploits Stochastic Resonance [PDF]

2022 Eur. J. Phys. 43 025703, 2022
The transduction process that occurs in the inner ear of the auditory system is a complex mechanism which requires a non-linear dynamical description. In addition to this, the stochastic phenomena that naturally arise in the inner ear during the transduction of an external sound into an electro-chemical signal must also be taken into account.
