Identification of novel immune molecular pathways and response markers to OmniGen-AF® supplementation in a rat model

Creator:: Branson, Jennifer A.
Abstract:: OmniGen-AF® (OG; Prince Agri Products, Inc., Quincy, IL) is a feed additive containing brewers dehydrated yeast and B-vitamins that supports immune function in ruminant livestock. Targeted profiling of immune-associated genes in whole blood is an effective platform for identification of a) novel molecular pathways and b) immune response markers to...

Large volume (1,800 µL) injection HPLC/MS/MS for the quantitative determination of illicit drugs and human urinary biomarkers in municipal wastewater

Creator:: Chiaia Hernandez, Aurea C.
Abstract:: A sensitive, selective, rapid analytical method based on large-volume injection (LVI) liquid chromatography/ tandem mass spectrometry was developed using commercially-available hardware that eliminates the need for either off-line or on-line solid phase extraction. Centrifugation followed by the direct injection of 1,800 µL was used for the quantification of illicit drugs,...

Soil quality assessment of Willamette Valley soils and root colonization potential by arbuscular mycorrhizal fungi

Creator:: Allen, Natalie M.
Abstract:: Interest in measuring soil quality continues to increase worldwide in view of demands on land productivity and the necessity to preserve soil resources, yet identification of suitable indicators for soil quality assessment is still evolving. This study adapted 10 biological, physical, and chemical indicators of soil quality identified by the...

The immunomodulatory role of canine mesenchymal stem cell-derived extracellular vesicles

Creator:: Phelps, Shannon M.
Abstract:: Immune-mediated diseases are a frequent cause of morbidity and mortality in canine patients. Treatments currently involve generalized suppression of the immune system, and corticosteroids are often used as a first-line agent. While often effective, corticosteroids are unlikely to induce remission without substantial side effects. Second-line immunosuppressive agents may be effective...

The effects of Phytophthora ramorum infection on hydraulic conductivity and tylosis formation in tanoak sapwood

Creator:: Collins, Bradley R.
Abstract:: Tanoak (Lithocarpus densiflorus), along with some other members of Fagaceae, are susceptible to sudden oak death caused by the oomycete Phytophthora ramorum. Symptoms of the disease include dying crowns, bleeding cankers, and eventually death of infected trees. The cause of mortality is not well understood, but recent research indicates that...

The effects of Phytophthora ramorum stem inoculation on aspects of tanoak physiology and xylem function in saplings and seedlings

Creator:: Stamm, Elizabeth A.
Abstract:: Phytophthora ramorum, an oomycete plant pathogen, is the causal agent of sudden oak death, a serious disease of Fagaceous trees in California and Oregon over the last decade. Tanoak (Notholithocarpus densiflorus) is one of the most susceptible host species, but the cause of host mortality is poorly understood. Previous research...

Residents’ drivers and barriers to participation in the Backyard Habitat Certification Program : Study of socio-ecological factors in Madison South neighborhood in NE Portland

Creator:: Powel, Jinnet
Abstract:: As urban development fractures and reduces available habitat for birds and other wildlife, conservationists are increasing pursuing strategies to improve the habitat value of privately owned yards in and around cities. The Backyard Habitat Certification Program is a collaborative effort between the Portland Audubon Society and the Columbia Land Trust...

Measuring in situ biotransformation in BTEX-contaminated groundwater

Creator:: Alumbaugh, Robert E.
Abstract:: Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

In situ transformation of toluene and xylene to benzylsuccinic acid analogs in contaminated groundwater

Creator:: Reusser, Dominik E.
Abstract:: The rate of removal of benzene, toluene, ethylbenzene and the xylene isomers (BTEX) from contaminated groundwater is needed to design remediation processes. Benzylsuccinic acid (BSA) and methyl-benzylsuccinic acid (methyl BSA) are unambiguous metabolites of anaerobic BTEX biodegradation. An analytical method for quantitative determination of BSA in groundwater samples was developed....

Enhancing Small Sample Foraminifera Analysis through Innovative Mass Spectrometry Techniques: A Pathway to Deeper Paleoceanographic Insights

Creator:: Meyer, Grace
Abstract:: Stable oxygen and stable carbon isotopes of foraminifera are widely applied in paleoceanographic reconstructions. Oxygen and carbon isotopes are typically measured using pooled sample analysis (i.e., the combination of several shells) or single-shell analysis (typically restricted to heavier shells that weigh above 10 µg). With pooled sample analysis, where many...
