Fibrinogen adsorption at heparinized silica interfaces : history dependence and protein concentration effects

Creator:: Joshi, Omkar
Abstract:: Adipic dihydrazide-modified heparin was prepared and subsequently immobilized on surface-activated silica wafers. X-ray photoelectron spectroscopy (XPS) was used to quantify the elemental composition of the silica surface at each stage of activation and results showed that successful immobilization had taken place. Contact angle measurements were made to verify the high...

Evaluation of the off-flavor in English sole (Parophrys vetulus) using descriptive analysis techniques and consumer testing

Creator:: Geise, Laura Ann
Abstract:: English sole (Parophrys vetulus) is a flatfish found in abundance in the Pacific Ocean and is part of the Pacific Northwest's and California's commercial trawl fishery. Stock levels of this fish are at all time highs but there are decreased landings due to low demand and acceptability. With new regulations...

Steps toward structure-assisted drug design

Creator:: Watts, K. Shawn
Abstract:: The three dimensional structure of both a ligand and its cognate receptor are required for the success of structure-assisted drug design. This thesis reports the crystal structure of hectochlorin, a small, bioactive molecule, and the steps toward determining the crystal structure of an RNA molecule that is an attractive target...

Characterization of rheological properties and thermal stability of fish myofibrillar proteins

Creator:: Esturk, Okan
Abstract:: Effects of moisture content, pH, and salt concentration on dynamic rheological properties and gel fracture quality of Pacific whiting surimi were investigated. Torsion tests showed that shear stress decreased rapidly and strain values decreased gradually as moisture concentration increased. As pH increased, fracture shear stress and strain values increased, whereas...

Purchasing and consumption behaviors, attitudes, opinions and expectations of Taiwanese urbanites toward cheese

Creator:: Tsai, I-Min
Abstract:: A focus group interview consisting of 25 international Taiwanese students and a consumer survey in which 793 native Taiwanese urbanites participated were conducted. Both studies investigated the purchasing and consumption behaviors, attitudes, opinions and expectations of Taiwanese people toward cheese. The focus group results provided good predictions and explanations of...

Yeast protein release during fermentation and aging in a model wine

Creator:: Rowe, Jeffrey D.
Abstract:: Yeast mannoproteins released during the process of aging wine on the yeast lees have been reported to make important contributions to wine quality. However, few mannoproteins have been identified in wine and their lifespan during aging is unknown. As a first step towards better understanding the contributions of yeast mannoproteins...

Impact of weak and strong acids on the destruction of lactic acid bacteria during high pressure processing

Creator:: Sarangapani, Rama Krishna
Abstract:: High hydrostatic pressure (HHP) affects the pH of weak acids due to an increased degree of acid dissociation while under pressure. The temporary pH reduction by high pressure in such a case may influence the barotolerance of microorganisms. The objective of this study was to determine the impact of weak...

Optimization studies in preparative chromatography of biomolecules

Creator:: Ramanan, Sundar
Abstract:: Optimization of preparative nonlinear chromatography was carried out for the first time for a biomolecule mixture. Conventional wisdom on optimization, which roots from analytical chromatography, dictates optimizing resolution in an analytical column and obtaining similar separation in a large column for isolation. Such a method of optimization significantly under uses...

Oligoribonucleotides directed at ribosomal protein binding sites as inhibitors of ribosomal small subunit assembly and as possible antibiotics

Creator:: Thompson, Cynthia Sue
Abstract:: The effects of oligoribonucleotides of identical or similar sequences to a ribosomal protein binding site, specifically S8, on prokaryotic 30S ribosomal assembly were investigated in Escherichia coli. The oligoribonucleotides were expected to bind to the target protein S8 and block its incorporation into the 30S subunit, resulting in a nonfunctional...

Effect of whey concentrate crystallization parameters on lactose crystal forms

Creator:: Nonnemacher, Melissa L.
Abstract:: Effects of whey concentrate crystallization parameters of temperature, pH, and length of time of crystallization on lactose crystal forms and amount of lactose crystallized were investigated. Effect of crystallization parameters on freeze-dried powder quality was also investigated. Lactose crystal forms were observed in x-ray crystal diffraction patterns of freeze-dried whey...
