Investigations of regulatory T cell induction by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin during a graft-versus-host response

Creator:: Marshall, Nikki B.
Abstract:: The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...

Assessment of Extraterrestrial Tracers Ir, Pt and ³He in Polar Ice Cores

Creator:: Mehmel, Nicholas C.
Abstract:: This thesis focuses on the investigation of extraterrestrial tracers Ir, Pt and 3He in polar ice cores. These tracers may be used to identify characteristics of interplanetary dust particles, and to quantify the flux of extraterrestrial material during impact events, certain volcanic eruptions, and stable background periods. In the first...

Tropical Fruit Aroma in Chardonnay: Impact of Fermentation Techniques on Volatile Ester and Thiol Concentrations, Tropical Fruit Aroma Perception, Preference, and Emotional Response

Creator:: Lucas, Chase J.
Abstract:: Tropical fruit aromas are prominent in wines like Sauvignon Blanc, one of the most abundant white wines in the United States. With high consumer interest for these aromas, it has become increasingly important to understand the factors that influence the desired tropical fruit aromas in white wines. Understanding the causes...

Impact of biased movement on marine protected area effectiveness

Creator:: Rekow, James Alexander
Abstract:: Fish mobility affects the distribution of commercially caught fish species in marine protected areas (MPAs) and unprotected areas, which we will call fishing grounds (FGs). Previous theoretical findings predicted that highly mobile fish would benefit little if at all from protection in MPAs (Demartini 1993, Walters et al. 1999). However,...

Part I: Synthetic studies toward the southern portion of Azaspiracid-1; Part II: Total synthesis of amphidinolide B₁ and the proposed structure of amphidinolide B₂

Creator:: Lu, Liang
Abstract:: The structural architecture present in marine toxin azaspiracid - 20 stereocenters, 9 rings, 3 separated spirocenters - has attracted considerable synthetic attention. Our efforts toward the synthesis of azaspiracid have led to the completion of both C₁-C₂₆ northern and C₂₇-C₄₀ southern halves. Herein, the synthesis of southern FGHI ring system...

Comparing Sediment Microbial Communities of Arctic Beaver Ponds to Tundra Lakes and Streams

Creator:: Shannon, Kelly
Abstract:: In recent decades the habitat of North American beaver (Castor canadensis) has expanded from boreal forests into pan-Arctic tundra ecosystems. It is unknown how the advance of beavers into Arctic watersheds will impact microbial communities responsible for the mineralization of organic matter (OM), which has implications for carbon cycling. To...

Tropical Fruit Aroma: Relevance to Oregon White Wines, the Effect of Winemaking Processes on Fermentation Esters and Volatile Thiol Levels, and the Relationship Between Sensory Perception and Volatile Chemistry

Creator:: Iobbi, Angelica
Abstract:: Aroma is one of the major components that determines the quality of wine and consumer acceptability. Fruitiness is a highly desirable aroma quality in white wines and has been well accepted by consumers across the globe. Tropical fruit aroma has been substantially studied in Sauvignon Blanc wines due to its...

The preparation and human taste detection of low degree of polymerization glucose oligomers

Creator:: Pullicin, Alexa J.
Abstract:: There is growing evidence that humans and other animals can taste certain starch hydrolysis products, namely, maltooligosaccharides (MOS), and that their detection is independent of the known sweet receptor, T1R2 T1R3. The overall goal of this study was to further investigate the taste perception of low degree-of-polymerization (DP) MOS in...

Bioherbicide use of plant defensive compounds in meadowfoam seed meal

Creator:: Intanon, Suphannika
Abstract:: Meadowfoam (Limnanthes alba Hartw. ex Benth) seed meal (MSM), a by-product of meadowfoam oil extraction, has a plant defensive compound known as glucosinolate glucolimnanthin (GLN). Myrosinase enzymes present in soil microbes and meadowfoam seeds can convert GLN to glucosinolate breakdown products (GBPs), which demonstrate herbicidal activity and have the potential...

An Application of Visual Management to Reduce In-house Material Handling Wastes in SMEs with High Product Variety and Low Volume

Creator:: Kopriva, Cody
Abstract:: Small and medium-sized enterprises that are characterized by high-mix, low-volume, and highly variable production operations often have unstructured material movement processes that are prone to material handling wastes. These sub-optimal material handling systems are oftentimes a result of small and medium-sized enterprise's limited resources. Current tools to assist organizations in...
