Ingestion of Microplastics in the Juvenile Black Rockfish (Sebastes melanops) from Oregon Coastal Sampling Sites

Creator:: Arnold, Madison A.
Abstract:: Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...

Discovery and Isolation of Bioactive Natural Products from Actinomycete Bacteria with an Examination ofInfectious Disease Drug Development and Application : A Comparison of the Developing and Developed Worlds

Creator:: Petrossian, Gregory
Abstract:: New antibiotic compounds with novel mechanisms of action have become essential in response to the recent paradigm of increasingly resistant strains of bacteria. Secondary metabolites (natural products) from bacteria such as Actinobacteria serve as lead compounds for the development of pharmaceutical drugs widely used to fight bacterial, viral and fungal...

Preliminary Evidence that the Microbial Community may Produce Aliphatic Constituents and Induce Soil Water Repellency as a Response to Desiccation

Creator:: Chilcote, Emma T.
Abstract:: Soil water repellency is one cause of rill soil erosion and overland flow that results in the loss of fertile topsoil. Previous research suggests that since microbial growth depends on temperature/moisture and follows diurnal and seasonal cycles, a biological mechanism would be able to explain the observed seasonality and climate...

Microbes may induce soil water repellency through the production of aliphatic constituents as a response to desiccation

Creator:: Chilcote, Emma T.
Abstract:: Soil water repellency may be influenced by microbes whereby they produce aliphatic constituents (non-wetting materials) that coat the soil particles when they are subjected to desiccation stress.

A Performance Evaluation of In-Stream Hatchboxes and Streamside Incubators for Chinook Salmon

Creator:: Howell, Meghan Z.
Abstract:: Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...

Impact of Polycyclic Aromatic Hydrocarbons on Barrier Function Toxicity in 3D Lung Model from Normal and Asthmatic Donor Cells

Creator:: Huynh, Celine T.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are known to cause adverse health effects in the human lung. Here, we evaluated biomarkers relevant for PAH toxicity in a 3D human primary bronchial epithelial cell (HBEC) model collected from normal and asthmatic donors. We previously found that PAHs decrease cellular barrier function integrity, which...

Age-related response of isolated rat hepatocytes to menadione and (R)-[alpha]-lipoic acid

Creator:: Graves, Jason T.
Abstract:: Age-related decline in the capacity of endogenous antioxidant systems complicates pharmaceutical use by the elderly by potentially increasing the toxicity of some compounds. Of particular interest is chemical detoxification via glutathione (GSH) and attendant GSH-requiring detoxification enzymes, e.g. GSH peroxidases (GPX) and GSH S-transferase (GST). These enzymes have been shown...

Addressing ALS: Corroborating the Methodology of Studying the P2X7R Complex

Creator:: Veytsman, Edward Y.
Abstract:: Amyotrophic lateral sclerosis (ALS) is characterized by the degeneration of motor neurons in the motor cortex and spinal cord. Recent evidence suggests that the purine receptor P2X7 (P2X7R) plays a central role in the pathology of ALS. Previous research indicates that P2X7R activation by oxidatively modified heat shock protein 90...

Urban Business Rodent Control Behavior and Attitudes Toward Rodents and Impact on Non-target Wildlife (Presentation), Urban business attitudes regarding rodents, rodent control methods, and impact on wildlife

Creator:: Arndt, Eva
Abstract:: Birds of prey and carnivorous mammals feed on small birds, rodents and other small mammals. Humans perceive many of the prey animals of these predators as well as the predators themselves, as “pests”, and seek to control them. Control methods for these unwanted pests, particularly rodents, have the potential to...
