  • Publication number: 20180263536
    Abstract: Hearing difficulties are the most commonly reported disabilities among Veterans. Blast exposures during explosive events likely play a role, given their propensity to directly damage both peripheral auditory system (PAS) and central auditory system (CAS) components. Post-blast PAS pathophysiology has been well-documented in both clinical case reports and laboratory investigations. In contrast, blast-induced CAS dysfunction remains under-studied, but has been hypothesized to contribute to an array of common Veteran behavioral complaints including learning, memory, communication, and emotional regulation. This investigation compared the effects of acute blast and non-blast acoustic impulse trauma in adult male Sprague-Dawley rats. An array of audiometric tests were utilized, including distortion product otoacoustic emissions (DPOAE), auditory brainstem responses (ABR), middle latency responses (MLR), and envelope following responses (EFR).

  • Patent number: 9687502
    Abstract: To achieve, an in vivo repair of injured mammalian nerve tissue, an effective amount of a biomembrane fusion agent is administered to the injured nerve tissue. The application of the biomembrane fusion agent may be performed by directly contacting the agent with the nerve tissue at the site of the injury. Alternatively, the biomembrane fusion agent is delivered to the site of the injury through the blood supply after administration of the biomembrane fusion agent to the patient. The administration is preferably by parenteral administration including including intravascular, intramuscular, subcutaneous, or intraperitoneal injection of an effective quantity of the biomembrane fusion agent so that an effective amount is delivered to the site of the nerve tissue injury.
