An Investigation into the Functional Properties of the Deafness Causing Protein Otoferlin

Creator:: Manchanda, Aayushi
Abstract:: Otoferlin is a C2-domain, transmembrane protein whose mutated form is responsible for the DFNB9 subtype of prelingual hearing impairment. Mutations in otoferlin cause an autosomal recessive, non-syndromic form of deafness that is characterized by auditory neuropathy/ auditory dissynchrony (AN/AD), meaning that the outer hair cells (OHCs) are normal, and the...

A double-stranded secondary structure for hyaluronic acid in aqueous-organic solvent as revealed by vacuum ultraviolet circular dichroism

Creator:: Staskus, Paul
Abstract:: The association of hyaluronic acid (HA) into a double stranded structure has been investigated by circular dichroism (CD) spectroscopy into the vacuum ultraviolet region. The CD of HA changes dramatically, monitoring a cooperative transition as the dielectric constant of an aqueous solution is reduced by adding organic solvents. This structural...

Ecological Effects of Reservoir Water Level Management and Implications for Juvenile Chinook Salmon

Creator:: Murphy, Christina A.
Abstract:: Large dams and their respective reservoirs can provide renewable energy and water security, but also profoundly alter riverine ecosystems. In the Pacific Northwest, dams and reservoirs cause discontinuities in river networks that have been particularly problematic for anadromous fishes. As barriers to the upstream and downstream migration of anadromous fishes,...

Controls on Process and Form in Alluvial and Bedrock Meandering Rivers

Creator:: Zunka, John P. P.
Abstract:: Bedrock meandering rivers are sinuous channels that pair steep bedrock outside banks with lower gradient slip-off slopes on the inside of bends. These rivers have the potential to record information on climatic and tectonic “external” forcings in their morphology (e.g., longitudinal profiles, strath terraces, channel and valley dimensions). However, geology...

Abstract:: A method based on fatty acid (FA) analysis is used to profile microbial community structure (MCS). Various extraction protocols are available, which alter the types of FAs extracted from soils. The more time consuming but widely used protocol extracts only FAs from phospholipids (PLFA). This technique is desirable because PLFAs...
