U-M scientists find gene for low-frequency hearing loss

... an assistant professor of otolaryngology-head and neck surgery in the U-M Medical School. "These proteins are produced in tiny amounts in the inner ear or cochlea - an area that is inaccessible for tissue sampling and difficult to study." Lesperance's research team worked closely with Burmeister and Iri...

Influence of gender on upper airway structure and function during obstructive sleep apnea
