Microgravity affects the hair cell ionic currents of the frog semicircular canals

, 2010
The effects of microgravity on the biophysical properties of frog labyrinthine hair cells have been examined by analyzing calcium and potassium currents in dissociated cells, using the patch-clamp technique.

Anatomical Study and Classification of Foramina of the Squamous Part of the Temporal Bone

Clinical Anatomy, EarlyView.
ABSTRACT The postglenoid foramen (PGF) is a rarely reported anatomical variant of the temporal bone, with limited data on its morphology, prevalence, and clinical relevance, particularly in non‐European populations. This study aimed to investigate the anatomy and frequency of foramina located on the squamous part of the temporal bone, including the PGF,

Experimental Investigation on Steam Generation Performance of a Solid Thermal Storage‐Based Steam Production System

Energy Science &Engineering, EarlyView.
1. Against the backdrop of the dual carbon goals and the transformation of the energy structure, traditional coal and natural gas boilers struggle to meet the demand for economical and stable steam supply in small and medium‐sized enterprises. In response, this study proposes a solid‐state thermal storage steam production system, aiming to provide a ...

Evaluation of the vestibulo-ocular reflex in head-tilt mutant mice

Biochemistry and Biophysics Reports
The vestibulo-ocular reflex (VOR) is an involuntary reflex essential for maintaining clear vision and balance during head movement. It stabilizes gaze by generating compensatory eye movements in the opposite direction to head movement, ensuring that the ...

Why the semicircular canals are not stimulated by linear accelerations

, 2019
: Head accelerations are sensed by the vestibular system in the inner ear. Linear accelerations stimulate the otolith organs, while the semicircular canals (SCC) sense angular accelerations.

Magnetic Vestibular Stimulation in Subjects with Unilateral Labyrinthine Disorders

Frontiers in Neurology, 2014
We recently discovered that static magnetic fields from high-strength MRI machines induce nystagmus in all normal humans, and that a magnetohydrodynamic (MHD) Lorentz force, derived from ionic currents in the endolymph and pushing on the cupula, best ...

Labyrinthine Abnormalities on MRI in Untreated Otosclerosis: Prevalence and Clinical Relevance

The Laryngoscope, EarlyView.
In untreated otosclerosis with labyrinthine symptoms, delayed 3D FLAIR MRI rarely demonstrates endolymphatic hydrops but frequently reveals blood–labyrinth barrier (BLB) disruption. BLB enhancement is spatially associated with cochlear endosteal and round window involvement and increases with the severity of the hearing loss phenotype.

Preferential Impairment of the Contralesional Posterior Semicircular Canal in Internuclear Ophthalmoplegia

Frontiers in Neurology, 2017
BackgroundThe vertical vestibulo-ocular reflex (VOR) may be impaired in internuclear ophthalmoplegia (INO) as the medial longitudinal fasciculus (MLF) conveys VOR-signals from the vertical semicircular canals.
