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...

Semi-volatile organic compounds and developing organisms : accumulation in California mountain tadpoles in the field and fish embryo exposures in the laboratory

Creator:: Stanley, Kerri A.
Abstract:: The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...

Energy utilization by young grass carp fed different diets

Creator:: Cai, Zhengwei
Abstract:: Effects of diet on food energy utilization by grass carp fed aquatic plants or formulated diets with varied lipid sources and levels are presented in three manuscripts. Significant effects of diet on food consumption, digestion, growth and muscle fatty acid (FA) composition of fingerling diploid grass carp fed aquatic macrophytes...

Mercury distribution in sediments and uptake into an aquatic food web at Cottage Grove Reservoir, Oregon

Creator:: Morgans, Donna L.
Abstract:: The Cottage Grove Reservoir has been impacted by a point source (Black Butte Mine), where mercury mining and processing has occurred within its watershed from the 1890's to the late 1960's. Total mercury concentrations in surface sediments transect samples, core samples, tributary samples, and representative food web species were measured...

Chlordecone (CD), a mixed steroid X receptor (SXR) and estrogen receptor alpha(ERα) agonist, altered hepatic cholesterol (CH) homeostasis and lipoprotein metabolism

Creator:: Lee, Junga
Abstract:: Overtly non-toxic doses of organochlorine (OC) insecticides perturb lipid homeostasis in mice and rats. To increase understanding of how chlordecone (CD), an OC insecticide, modulates cholesterol (CH) homeostasis, we determined the effect of CD pretreatment on the tissue and hepatic subcellular distribution of exogenous [¹⁴C]CH. Corn oil alone or CD...

Developmental axial skeletal deformities : baseline study with a zebrafish model

Creator:: Harden, Jon M.
Abstract:: The aim of this study was to assess sensitivity of early life stage zebrafish to cadmium (Cd). Embryos and larva were exposed to Cd before the formation of skeletal elements. Exposure times were selected to determine whether Cd perturbed developmental processes that lead to skeletal deformities, and to characterize the...

Point and nonpoint source mercury pollution of Oregon Reservoirs

Creator:: Park, Jeong-Gue
Abstract:: Two Oregon reservoirs contaminated by different mercury sources were compared for mercury distribution in sediment and bioaccumulation by fish. The average mercury concentration in the sediment of Cottage Grove reservoir (0.67 ± 0.05 μg/g dry wt) was higher than for Dorena Reservoir (0.12 ± 0.01 μg/g dry wt). Sediment mercury...

Assessing mechanisms of immunotoxicity for polycyclic aromatic hydrocarbons in rainbow trout (Oncorhynchus mykiss)

Creator:: Bravo, Claudia F.
Abstract:: During the past 30 years, numerous studies have focused on the toxicities of polycyclic aromatic hydrocarbons (PAH). Laboratory and field studies have helped elucidate the detrimental effects of these chemicals on growth, reproduction and immune response. Polycyclic aromatic hydrocarbons are in the priority list of chemicals to be studied by...
