Zebrafish swimming behavior as a biomarker for ototoxicity-induced hair cell damage: a high-throughput drug development platform targeting hearing loss.

Hearing loss is one of the most common human sensory disabilities, adversely affecting communication, socialization, mood, physical functioning, and quality of life. In addition to age and noise-induced damage, ototoxicity is a common cause of sensorineural hearing loss with chemotherapeutic agents, for example, cisplatin, being a major contributor. Zebrafish (Danio rerio) are an excellent model to study hearing loss as they have neurosensory hair cells on their body surface that are structurally similar to those within the human inner ear.

The Solid Component of Radiographically Non-Growing, Post-Radiated Vestibular Schwannoma Retains Proliferative Capacity: Implications for Patient Counseling.

Objective: Nearly all radiated vestibular schwannomas (VS) have solid tissue remaining at the radiation bed. The viability and proliferation capacity of this tissue has never been objectively assessed. The goals of our study were to (1) determine whether this tissue retains the morphological and immunohistochemical features of VS and (2) evaluate whether the tissue is capable of proliferation in cell culture.
