In vivo assessment of nanomaterial-induced toxicity using embryonic zebrafish

Creator:: Usenko, Crystal Y.
Abstract:: Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...

Environmental contaminants in male river otters collected from Oregon and Washington, 1994-99, with reproductive organ hypoplasia observed in otter males

Creator:: Grove, Robert Allan
Abstract:: A large number of river otter (Lontra canadensis) males were collected from areas of high and low contaminant concentrations throughout western Oregon and Washington during the fall and winter of 1994-99. Few significant non-reproductive organ morphometric differences were found in the large series of male otters collected, except for adrenal...

Unraveling tissue regeneration using chemical genetics

Creator:: Mathew, Lijoy K.
Abstract:: The emerging field of regenerative medicine is mainly approached by two different aspects. First is the use of stem cell based models to generate a suite of differentiated cells for therapeutic applications and the alternative approach is to utilize the non-mammalian models that have the inherent capacity to regenerate their...

Antioxidant enzyme response in rainbow trout (Oncorhynchus mykiss) after subchronic exposure to an environmentally-relevant polycyclic aromatic hydrocarbon mixture

Creator:: Norby, Tyler S.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are significant pollutants in aquatic environments. Many are carcinogenic and lead to DNA fragmentation and adduct formation in marine and freshwater organisms. Previous research demonstrates that rainbow trout (Oncorhynchus mykiss) compensate to long-term PAH dietary exposures and reduce the DNA damage. The aim of this study...

Effects of esfenvalerate on native macroinvertebrates representative of Pacific Northwest streams

Creator:: Johnson, Katherine R.
Abstract:: Aquatic insects are essential components of healthy stream ecosystems, contributing to nutrient cycling, trophic dynamics and other ecological functions. Aquatic insect species, particularly those in the orders Ephemeroptera, Plecoptera and Trichoptera (EPT taxa) are however, extremely sensitive to insecticide contamination. Given that urban and agricultural use of synthetic pyrethroid insecticides...

Final report : environmental stresses and skeletal deformities in fish from the Willamette River, Oregon, USA

Creator:: Villeneuve, Daniel L., Curtis, Lawrence R., Jenkins, Jeffrey J., Warner, Kara E., Tilton, Fred A., Kent, Michael L., Watral, Virginia G., Cunningham, Michael E., Markle, Douglas F., Sethajintanin, Doolalai, Krissanakriangkrai, Oraphin, Johnson, Eugene R., Grove, Robert Allan, Anderson, Kim A., Oregon State University. Department of Microbiology, Oregon State University. Department of Environmental and Molecular Toxicology, Oregon State University. Department of Fisheries and Wildlife, and Institute for Natural Resources
Abstract:: The Willamette River, one of only 14 American Heritage Rivers, flows through the most densely populated and agriculturally productive region of Oregon. Previous biological monitoring of Willamette River fish detected elevated frequencies of skeletal deformities in fish from certain areas of the lower (NP [NP], rivermile [RM] 26-55) and middle...

Molecular characterization of bacterial populations implicated inthe anaerobic metabolism of toxic plant alkaloids from two different experimental and environmental sources

Creator:: Rattray, Rogan MacKay
Abstract:: There have been many studies that describe the protective degradation or metabolism of potentially harmful plant toxins, such as, mimosine from Leucaena leuconcephala, pyrrolizidine alkaloids from tansy ragwort (Senecio jacobaea), oxalate and some mycotoxins by rumen microbes. There are many cases of plant-related toxicoses suffered by ruminant animals where there...

Quantitative determination of emerging contaminants, solvent stabilizers and fullerene nanomaterials, in biological and environmental systems

Creator:: Isaacson, Carl W.
Abstract:: To determine the impact of emerging environmental contaminants on human and environmental health, quantitative analytical methods are required. Analysis of emerging contaminants is hampered by their widely varying physical-chemical properties. Therefore quantitative analytical methods must be developed to determine the behavior of emerging contaminants in environmental systems. A quantitative analytical...

Heat shock proteins and physiological stress in redband rainbow trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River, Oregon

Creator:: Feldhaus, Joseph W.
Abstract:: The goal of this research was to characterize thermal habitat requirements for juvenile redband steelhead trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River (SFJD), Oregon using physiological indicators of fish condition. Physiological indices of fish condition measured were whole body lipid content and heat shock proteins, specifically...
