L-type Ca 2+ channels (LTCCs) drive the bulk of voltage-gated Ca 2+ entry in vertebrate inner ear hair cells (HCs) and are essential for mammalian auditory processing. (jneurosci.org)
Increasing age leads to degeneration of cochlear tissues, including the sensory hair cells and stria vascularis. (bvsalud.org)
Vestibular6
The extent to which auditory and vestibular functions are impaired in individuals with type-2 diabetes mellitus is still under debate. (thieme-connect.com)
Objective To systematically review studies focusing on auditory and vestibular functions in individuals with type-2 diabetes mellitus. (thieme-connect.com)
Out of 33 full-length articles, 26 evaluated the functioning of the auditory system, while 7 evaluated the functioning of the vestibular system. (thieme-connect.com)
Most studies related to auditory functioning reported a significant effect of type-2 diabetes mellitus on the peripheral auditory system, whereas studies on vestibular functioning reported no significant effect of diabetes mellitus on the functioning of the peripheral vestibular end-organ. (thieme-connect.com)
Conclusion Overall, the results of various audiological and peripheral vestibular tests reveal distinctive peripheral and/or central auditory and vestibular end-organ impairments in individuals with type-2 diabetes mellitus. (thieme-connect.com)
Acoustic neuromas are intracranial, extra-axial tumors that arise from the Schwann cell sheath investing either the vestibular or cochlear nerve. (medscape.com)
Nerve2
Vastly improved imaging techniques permitting early diagnosis, adaptation of the microscope to the operating theater, development of facial and auditory nerve monitoring techniques, improved anesthesia, and improved perioperative management have all contributed to improved outcomes. (medscape.com)
However, iodine stained samples of cichlids [ 5 ] did not provide a sufficient contrast to discriminate otolith, otolithic membrane, maculae, and innervating nerve fibers of the VIII th cranial nerve. (biomedcentral.com)
Responses1
To explore the effects of cochlear hair cell displacement, researchers have previously monitored functional and mechanical responses during low-frequency (LF) acoustic stimulation of the cochlea. (bvsalud.org)
Studies2
While a number of studies have illustrated and analyzed 3D models of inner ears in higher vertebrates, inner ears in fishes have rarely been investigated in 3D, especially with regard to the sensory epithelia of the end organs, the maculae. (biomedcentral.com)
Future studies investigating functional morphology, phylogenetic potential of inner ear features, or evolution of hearing and inner ear specialization in fishes may benefit from the use of 3D models of inner ears and maculae. (biomedcentral.com)

Important1
It has been suggested that the 3D curvature of these maculae may also play an important role in hearing abilities in fishes. (biomedcentral.com)
High3
Comparison with maculae that have been 3D reconstructed based on histological serial sections and phalloidin-stained maculae showed high congruence in overall shape of the maculae studied here. (biomedcentral.com)
PTA staining and subsequent high-resolution contrast enhanced microCT imaging is a powerful method to obtain 3D models of fish inner ears and maculae in a fast and more reliable manner. (biomedcentral.com)
Our results indicate that reliable 3D reconstructions of inner ears including otoliths and maculae can be obtained by using high-resolution microCT imaging of specimens stained with phosphotungstic acid. (biomedcentral.com)
Sections1
2 ]). These reconstructions based on histological serial sections were labor-intensive and results were in part uneven as maculae were prone to distortion or artifacts such as disruption during dehydration or embedding procedures. (biomedcentral.com)
Account2
Acoustic neuromas account for approximately 80% of tumors found within the cerebellopontine angle. (medscape.com)
As has already been stated by Platt and Popper (1981) [ 3 ], orientation patterns should preferably take into account the three dimensional structure of sensory epithelia. (biomedcentral.com)
Form1
Serial publications are separated by form, and are assigned call numbers within several broad categories. (nih.gov)
