Organic Phase Inter-Ligand and Metal-Ligand Speciation in TALSPEAK and ALSEP Solvent Extraction Systems

Creator:: Gullekson, Brian J.
Abstract:: Partitioning of trivalent actinides (in particular, americium and curium) from the fission produced light lanthanides is a major concern of used nuclear fuel reprocessing for the purposes of waste disposal. Several solvent extraction processes have been developed to address these chemically difficult separations. The historically employed TALSPEAK Process utilizes di-2-ethylhexyl...

Examination of Multiple Air Pollutant Exposure, the Food Environment, and Low Birth Weight in Los Angeles, County

Creator:: Coker, Eric S.
Abstract:: Exposure to urban outdoor air pollution is ubiquitous and low birth weight represents an important health disparity in the United States. While previous research suggests that exposure to outdoor air pollutants are associated with term low birth weight, few studies have evaluated the effects of multipollutant outdoor air exposures or...

Childhood cancer and spatial analyses of benzene exposure in Texas

Creator:: Roberts, Mark T.
Abstract:: Childhood cancers are rare diseases that affect 188 children in Texas for every million born. Leukemia is the most common childhood cancer and accounts for roughly one third of childhood cancer cases. However, it is estimated that only 10% of childhood cancer cases can be explained by known risk factors....

Classifying polycyclic aromatic hydrocarbon bioactivities using phenotypic screening and transcriptomics in the developmental zebrafish model

Creator:: Geier, Mitra Celestine
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants that occur in complex mixtures. These environmental mixtures can consist of both parent PAHs and their derivatives. Several parent PAHs are known or suspected mutagens and/or carcinogens, and a handful of PAH derivatives are known to be more potent mutagens and/or carcinogens...

In Utero Exposure to Arsenic and Mercury : Epigenome-Wide Associations and Newborn Health Outcomes

Creator:: Cardenas, Andres
Abstract:: Mercury and arsenic are known developmental toxicants and environmental exposures are ubiquitous worldwide from natural and anthropogenic sources. Prenatal exposure to both contaminants are independently associated with adverse perinatal health outcomes and latent disease risk that could be in part mediated by epigenetic reprogramming events. Fetal programming events involving DNA...

Low-Dose Ionizing Radiation Solid Cancer Risk in Adults : Radiation Hormesis Study Design

Creator:: Alhussan, Abdulaziz S.
Abstract:: Cancer risk at low-dose ionizing radiation has been the subject of great scientific controversy in the past century. The clear majority of national and international radiation protection regulators adopt the linear no-threshold (LNT) model based on the atomic-bomb survivors Life Span Study (LSS) for solid cancer risk assessment. The LNT...

Embryonic and Larval Zebrafish Bioassays for Biomedical Research : The Larval Photomotor Response Screening Assay and Phenotype

Creator:: Fisher, Joseph A.
Abstract:: Laboratories around the world are using the zebrafish model for biomedical research and conducting investigations using morphological, physiological, behavioral, and genomic endpoints. All assays provide information, but physiological and behavioral endpoints or phenotypes are a fast way to understand how an animal is responding to its environment. We investigate the...

Evaluation of bacterial community indicators of stream sanitary and ecological condition

Creator:: Bracken, Caragwen L.
Abstract:: The focus of this research was to develop bacterial community indicators of stream sanitary and ecological condition. The first study compared substrate utilization patterns between centrifuged and uncentrifuged split samples. We found a shift in the relative proportion of each group of bacteria following centrifugation, with a marked increased in...

Ethnic, Age, and Gender Comparisons in Mediation of Socio-Cultural and Intrapersonal Influences on BMI by Physical Activity and Dietary Intake among California Adolescents

Creator:: Le, Binh T.
Abstract:: In the U.S., childhood overweight and obesity has grown to epidemic levels. The National Survey of Children’s Health (NSCH) found that nationwide, approximately 32% of children 10–17 years old are identified as overweight, over half of them (nearly 17%) are obese. This is a concern because these rates continue to...

Measuring Health Beliefs About UV Exposure Among Oregon College Students

Creator:: Julian, Anne K.
Abstract:: Exposure to ultraviolet (UV) radiation is a primary cause of melanoma and non-melanoma skin cancer and thus represents a critical public health concern. Skin cancer risk behavior research lacks an instrument designed to assess health beliefs about UV exposure that may increase skin cancer risk by increasing risky UV exposure...
