Fungal endophytes as source to combat bacterial infections

Creator:: Green, Jaimie R
Abstract:: Endophytes, foliage inhabiting fungi, are an unexplored source of fungal biodiversity and a potential resource for the production of bioactive natural products. In this research, leaf tissues from the species Arbutus menziesii, Rhododendron macrophyllum and the genus, Ilex and Salix were collected for the isolation of endophytic fungi. Fungal extracts...

Soil Fire Ecology: Assessing Wildfire Severity Impacts on Pacific Northwest Forest Soil Carbon

Creator:: Fleetwood, Shea
Abstract:: Pacific Northwest temperate rainforests are anticipated to experience increasingly frequent and severe wildfires in the foreseeable future due to climate change, increased fuel loads, and deforestation. Soil, underlying these forests, is the largest terrestrial carbon (“C”) reservoir. Fire disturbance influences soil C persistence, the timeframe and magnitude of which remain...

Enhancing Protocols to Improve Consistency Across Nanotoxicology Studies

Creator:: Luker, Sabrina R.
Abstract:: In current nanotoxicology research, there is a lack of standardization in reporting of zebrafish exposure media and sonication practices. This lack of standardization in use and reporting methods has made reproducing nanoparticle (NP) toxicity results between labs a common issue. It is important to have a standardized way of reporting...

Characterizing PM2.5 with Different Source Contributions

Creator:: Perez, Allison Mae S.
Abstract:: Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

Partial purification of endo-1,4-β-D-glucanase I of Trichoderma reesei and use in small-scale enzymatic hydrolysis of cellulose

Creator:: Pautsch, Lindsay
Abstract:: In order to reduce the cost of lignocellulosic ethanol production, a model was previously developed to predict the amount of fermentable sugar released based on parameters concerning both biomass and enzymes. To validate this model, enzymatic hydrolysis must be carried out using individual purified cellulase enzymes. Endo-1,4-β-D-glucanase I (EG I),...

Genotyping Cytochrome P450 1B1*3(Phase I) and Glutathione S-transferase Mu 1 null (Phase II), Metabolizing Enzymes in a [14C]Benzo[a]pyrene Human Micro Dosing Study

Creator:: Luo, Yun L.
Abstract:: Polycyclic Aromatic Hydrocarbons (PAHs) have been studied for their carcinogenic toxicity. PAHs are formed by incomplete carbon combustion. Benzo[a]pyrene (BaP) is an IARC classified Class 1 Human carcinogenic PAH. New studies are conducted to gain a better understanding of PAHs and how to reduce exposure. Glutathione S-transferase M 1 (GSTM1...

MatTek™ EpiIntestinal™ a 3D Small Intestine Epithelial Cell Culture Model For In Vitro Screening in Dietary Chemopreventive Agents

Creator:: Raymundo, Wilfrido E.
Abstract:: Testing the many potential chemoprevention agents from dietary sources in animal or human models is expensive and takes a long time. In vitro models can be useful for screening the right compounds to use in larger studies. We tested the MatTek™ EpiIntestinal™ small intestine epithelial 3D cell culture model for...

Impact of lignin on efficiency of small-scale enzymatic hydrolysis of lignocellulosic biomass

Creator:: Potapchuk, Angelica
Abstract:: Energy production and consumption is a major environmental and economic concern in the world today. Biofuel produced from lignocellulosic biomass is being explored as an alternative energy source to petroleum. Lignocellulosic biomass is comprised of cellulose, hemicellulose, and lignin. To produce biofuels, lignocellulosic biomass must be broken down to expose...

Analysis of boscalid resistance of isolates of Botrytis cinerea

Creator:: Villanueva, Brenda
Abstract:: Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in...

Metabolic Effects in C57B/6J Mice Fed a High-Fat Diet Supplemented with Chromium Picolinate and Chromium Yeast

Creator:: Yu, Wesley
Abstract:: An estimated total of 30.3 million people have diabetes in the United States, a disease characterized by chronic elevation in blood glucose which over time, can lead to a host of health problems. Currently the most common types of diabetes are type 1, type 2, and gestational. The principal hormone...
