Purinergic Signalling in the Cochlea

International Journal of Molecular Sciences, 2022
The mammalian cochlea is the sensory organ of hearing with a delicate, highly organised structure that supports unique operating mechanisms. ATP release from the secretory tissues of the cochlear lateral wall (stria vascularis) triggers numerous physiological responses by activating P2 receptors in sensory, supporting and neural tissues.

Music Interventions in Hyperacute and Acute Stroke Patients: A Randomized Controlled Pilot Feasibility Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Music interventions have been shown to have beneficial effects on hemodynamic parameters, pain, and anxiety in various medical settings. However, music interventions in the setting of acute stroke have not been studied. The objective of this trial was to perform a pilot feasibility study of music interventions in the setting of acute

Pencil‐beam scanning proton therapy for the treatment of glomus jugulare tumours

Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 456-462, December 2022., 2022
The rare locally destructive glomus jugulare tumours could be treated using pencil‐beam scanning proton therapy (an alternative to surgery). Proton therapy provides good local control and acceptable toxicity. This paper reports treatment outcomes, acute and early late toxicities of 12 patients with glomus jugulare tumours.

Modified protein expression in the tectorial membrane of the cochlea reveals roles for the striated sheet matrix [PDF]

, 2015
The tectorial membrane (TM) of the mammalian cochlea is a complex extracellular matrix which, in response to acoustic stimulation, displaces the hair bundles of outer hair cells (OHCs), thereby initiating sensory transduction and amplification.

A Gradient of Single-Channel Conductance in the Cochlea [PDF]

Neuron, 2003
AbstractFrequency tuning in the vertebrate cochlea requires a continuously varying amplifier in auditory hair cells. In this issue of Neuron, Ricci et al. show that the mechanosensitive transduction channel, a possible amplifier component, has a single-channel conductance that increases systematically along the frequency axis of the turtle cochlea.

Micro‐ and Nano‐Bots for Infection Control

Advanced Materials, EarlyView.
This review presents a strategic vision for integrating micro‐ and nanobots in the pipeline for infection diagnosis, prevention, and treatment. To develop these robots as a practical solution for infection management, their design principles are clarified based on their propulsion mechanisms and then categorized infection management domains based on ...

Studies of intercellular Ca2+ signaling and gap-junction coupling in the developing cochlea of mouse models affected by congenital hearing loss [PDF]

, 2013
Connexin 26 (Cx26) and connexin 30 (Cx30) form gap junction channels that allow the intercellular diffusion of the Ca2+ mobilizing second messenger IP3.

Cochlear-bone wave can yield a hearing sensation as well as otoacoustic emission

, 2014
A hearing sensation arises when the elastic basilar membrane inside the cochlea vibrates. The basilar membrane is typically set into motion through airborne sound that displaces the middle ear and induces a pressure difference across the membrane.

Mechanics of the Mammalian Cochlea [PDF]

Physiological Reviews, 2001
In mammals, environmental sounds stimulate the auditory receptor, the cochlea, via vibrations of the stapes, the innermost of the middle ear ossicles. These vibrations produce displacement waves that travel on the elongated and spirally wound basilar membrane (BM). As they travel, waves grow in amplitude, reaching a maximum and then dying out.
