Next Generation Sequencing Reveals Gene Expression Patterns in the Zebrafish Inner Ear Following Growth Hormone Injection
<p>Loss of hair cells due to acoustic trauma results in the loss of hearing. In humans, unlike other vertebrates, the mechanism of hair cell regeneration is not possible. The molecular mechanisms that underlie this regeneration in nonmammalian vertebrates remain elusive. To understand the gene …

Optimizing Conditions for Cloning cDNA from Chicken Brain
Acoustic over stimulation can lead to hair cell loss in the auditory epithelium. Hair cell loss or damage in mammals often results in decreased auditory sensitivity which is irreversible. However for birds, hair cells which are damaged by acoustic trauma or ototoxic drugs may be replaced by …

The Time-Course of the Effects of Growth Hormone During Zebrafish (<i>DANIO RERIO</i>) Auditory Hair Cell Regeneration
… apoptosis in the zebrafish inner ear following acoustic trauma. The time-course of hair cell bundle density, cell proliferation, and apoptosis was established by combining data for baseline fishes and sound-exposed fishes at post-sound exposure day 1 (psed1), psed2, and psed3. GH-injected fish …

The Effects of Growth Hormone in the Inner Ear of Zebrafish (<i>Danio rerio</i>) during Hair Cell Regeneration
… GH may suppress hair cell death induced by acoustic trauma. Higher levels of cell proliferation were also observed in the ears of GH-injected fish, indicating that GH is capable of activating cell mitosis in the zebrafish auditory system. Following sound exposure, the GH-injected group …

Slow modulation of cochlear response by the olivocochlear efferent system elicited by sustained noise or threshold elevation in the contralateral ear
… hearing, and suppresses distortion product otoacoustic emissions (DPOAEs), compound action potentials (CAPs), and round window noise. In contrast to the MOC slow effect, which has been reported for sustained shockevoked MOC activity, MOC delayed suppression does not build up in the outer hair …

PLASTIC CHANGES IN THE INHIBITORY GLYCINE SYSTEM OF THE DORSAL COCHLEAR NUCLEUS (DCN) IN A RAT MODEL OF TINNITUS
… receptor trafficking change following acoustic trauma. BDNF and TrkB were also increased over fusiform cells in both young and aged exposed rats. [3H] strychnine binding was used to evaluate DCN GlyR pharmacology and function following sound exposure. The age-related decrease in GlyR …

Role of pericytes in the barrier task
… limited to, sudden sensorineural hearing loss, acoustic trauma, and inflammation of the cochlea. Understanding the role of PCs in pathophysiology, particularly how it relates to microvascular degeneration and pathological neovascularisation, is critical in order for the development of novel …

Repurposing Oseltamivir, a Commonly Prescribed Influenza Antiviral, for the Prevention of Noise- and Cisplatin-Induced Hearing Loss
… candidate in both cisplatin chemotherapy and traumatic noise exposure.

Dorsal Cochlear Nucleus Output Neurons in Young and Aged Rats
… cells, receive excitatory inputs from the acoustic nerve, which is modulated and shaped by inhibitory glycinergic inputs from nearby vertical cells. A number of studies in rodents suggested an age-related impairment of glycinergic neurotransmission. To access the functional impact of …

CANNABINOID RECEPTORS (CB) IN COCHLEA: CHARACTERIZATION AND OTOPROTECTIVE FUNCTIONS
… agents such as cisplatin, aminoglycosides and acoustic trauma. These insults can trigger chronic production of reactive oxygen species (ROS) in regions of cochlea such as organ of Corti, stria vascularis (SVA), spiral ligament (SL) and spiral ganglion neurons (SG). This leads to increased …

Evaluation of a Test Method for Assessing Horizontal Localization and Auditory Learning with Electronic Pass-through Hearing Protection
… and potential threats. However, hearing loss, acoustic trauma, or the use of hearing protection can diminish this vital ability to locate sounds in the environment accurately. The introduction of electronically modulated hearing protection and enhancement devices (HPED) is an attempt to improve …

Hearing Sensitivity and the Effect of Sound Exposure on the Axolotl (Ambystoma Mexicanum)
… hearing sensitivity after damage following acoustical trauma. This study is the first to document hearing loss in the axolotl. Future studies are needed to correlate this hearing loss and recovery to sensory hair cell loss and regeneration in the axolotl inner ear.</p>
