The Contributions of Age Related Changes in the Sound Localization Pathway to Central Hearing Loss

Jan 14th, 2022 - Age-related hearing loss, presbycusis, affects up to 50% of American adults. There are two main causes for presbycusis: 1) Progressive death of hair cells in the inner ear, and 2) Central hearing loss, or the reduced ability to decipher the sound source of interest from other competing sounds in a multi-source complex environment. The first cause is better understood and treatment options, such...

Impact of Elastin Mediated Vascular Stiffness on End Organs

Jan 14th, 2022 - Elasticity in the aorta buffers the body from damage due to pulsatile blood flow. Data from humans and mice show that with increasing age, vessels lose elasticity and become stiff. Vascular stiffness is associated with progressive cognitive impairment and dementia in aging adults, but little is known about the effects of early-onset/congenital vascular stiffness. Similarly, elastin-mediated art...

Most pre-hospital emergency medical service (EMS) agencies use radios systems for audio communication betw...

Cholinergic Receptor Imaging in Dystonia

Jan 14th, 2022 - Dystonia is a heterogeneous group of movement disorders characterized by abnormal muscle contractions resulting in abnormal postures and movements. The spectrum of dystonia includes focal, segmental, multifocal, and generalized presentations with a broad range of age of onset. An example of a focal dystonia is cervical dystonia. The pathophysiology of dystonia is unclear, but prior neuroimaging...
