Cortical Neurophysiologic Correlates Of Auditory Threshold In Adults And Children With Normal Hearing And Auditory Neuropathy Spectrum Disorder, Garrett Cardon, Anu Sharma

Faculty Publications

Purpose: Auditory threshold estimation using the auditory brainstem response or auditory steady state response is limited in some populations (e.g., individuals with auditory neuropathy spectrum disorder [ANSD] or those who have difficulty remaining still during testing and cannot tolerate general anesthetic). However, cortical auditory evoked potentials (CAEPs) can be recorded in many such patients and have been employed in threshold approximation. Thus, we studied CAEP estimates of auditory thresholds in participants with normal hearing, sensorineural hearing loss, and ANSD. Method: We recorded CAEPs at varying intensity levels to speech (i.e., /ba/) and tones (i.e., 1 kHz) to estimate auditory thresholds …


Structural And Biophysical Investigations Into The Mechanism Of Hiv-1 Envelope Incorporation, Richard Elliot Murphy Jan 2020

Structural And Biophysical Investigations Into The Mechanism Of Hiv-1 Envelope Incorporation, Richard Elliot Murphy

All ETDs from UAB

Recent advancements in drug therapies and patient care have drastically improved upon the mortality rates of HIV-1 infected individuals. Many of these therapies were developed or improved upon using structure-based techniques, which underscores the importance of obtaining atomic level structural data critical to the understanding of essential mechanisms in the replication cycle of HIV-1. One such process which remains poorly understood on the structural level is the incorporation of the envelope glycoprotein (Env) into budding virus particles. The Env protein mediates viral infection of host cells, and there is strong evidence suggesting that incorporation of Env is mediated by an …
