The effects of exercise on physiological and psychological variables in cancer patients following clinical treatment

Creator:: Burnham, Timothy Robert
Abstract:: The treatment of certain types of cancers brings with it serious physiological and psychological side effects in cancer survivors, including: decreased aerobic capacity, muscle wasting, body composition changes, fatigue, and a diminished overall quality of life. Exercise may directly influence the physiological side effects of cancer and cancer treatment, and...

Elucidating the Signaling Events Downstream of Aryl Hydrocarbon Receptor Activation in Zebrafish

Creator:: Shankar, Prarthana
Abstract:: All animals have developed the critical ability to detect, respond to, and detoxify a large array of environmental chemicals and stressors that can cause adverse health effects. Important examples of landmark contaminants around the world are polycyclic aromatic hydrocarbons (PAHs) and dioxins, both of which can act via the aryl...

Size- and Oxidation-Dependent Toxicity of Graphene Oxide Nanomaterials in Embryonic Zebrafish

Creator:: Lopez, Ryan
Abstract:: Graphene and its derivatives are two-dimensional hexagonal lattices that possess desirable physicochemical properties leading to an ever-expanding list of industrial and biomedical uses. Graphene oxides (GOs) are becoming a popular graphene alternative and while there have been human safety studies, investigations of developmental toxicity are lacking. The use of distinct...

Evaluating the Dietary Toxicity of Per- and Polyfluoroalkyl Substances and Development of a High Throughput Non-Invasive Zebrafish Cortisol Assay

Creator:: Leong, Connor A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are contaminants of concern because they do not readily degrade in the environment. Some in vivo studies report that PFAS alter neurological development and are carcinogenic. Perfluorohexanesulfonamide (FHxSA) and 6:2 fluorotelomer sulfonate (6:2 FTS) are two PFASs, which are often detected in drinking water sources....

Creating High Throughput Low Cost Analysis of Different Labor-Intensive Repetitive Research Processes

Creator:: Sullivan, Christopher M.
Abstract:: Many research projects suffer from limited data causing poor statistical analysis or limited results. The movement to high throughput methods has been building for many years and cross many different disciplines. Lots of these methods start out using pathways that generate large amounts of data but have limited methods to...

Elucidating Structure-bioactivity Relationships and Modes of Action of Per- and Polyfluoroalkyl Substance Toxicity in Zebrafish

Creator:: Rericha, Yvonne
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a broad class of anthropogenic chemicals characterized by highly stable carbon-fluorine (C-F) bonds. PFAS are widely used in industrial and consumer products for their surface-active and stain-resistant properties and are ubiquitously detected in environmental media, biota, and human biomatrices. Although some PFAS are known...

Advanced Approaches in Hazard Assessment of Polycyclic Aromatic Hydrocarbons Using Zebrafish

Creator:: Wilson, Lindsay B.
Abstract:: The field of toxicology is challenged with a vast number of environmental chemicals and mixtures to which humans and ecosystems are exposed with limited toxicity data available. Chemical hazard assessment traditionally utilizes mammalian models and can be both cost- and time-limiting and may pose ethical concerns. To rapidly tackle this...

Recycling knowledge, attitudes and behavior for on-campus and off-campus students in organized living groups at Oregon State University

Creator:: Rainey, Rochelle C.
Abstract:: The purpose of this study was to examine Oregon State University students' self-reported knowledge, attitudes, and behavior about recycling. Students living in on-campus and off-campus organized living groups were mailed a four-page survey with questions about their recycling activities, their attitudes about recycling, their opinions of the effectiveness of the...

Bird communities in managed conifer stands in the Oregon Cascades : habitat associations and nest predation

Creator:: Vega, Robyn M. S.
Abstract:: Green-tree retention is being implemented on state and federal lands in Oregon. Silvicultural prescriptions with tree and snag retention are thought to mimic natural disturbance patterns in the Pacific Northwest more closely than traditional silvicultural practices, which reduce structural complexity. The effects of green-tree retention on native bird species in...

Sub-diffraction light propagation and imaging in planar negative refraction waveguides

Creator:: Wangberg, Robyn
Abstract:: In this dissertation we study the electromagnetic properties of planar waveguides with non-magnetic strongly anisotropic dielectric cores. We develop an analytical description of the mode propagation in these systems and show that the index of refraction can be either positive or negative depending on the specific material parameters. Propagating modes...

Methodological and managerial applications of the structural norm approach to social and facility capacity indicators in Hawai'i's coastal recreation areas

Creator:: Ceurvorst, Robyn L.
Abstract:: Tropical coastal and marine areas are popular for recreation, leisure, and tourism activities, but these activities can cause social (e.g., crowding), ecological (e.g., coral trampling), and managerial impacts (e.g., pressure on facilities). The concept of norms is one approach for examining user acceptance or tolerance of these impacts. This dissertation...

The effects of a 7-month high impact jumping intervention on bone mass in pre-pubescent boys and girls

Creator:: Fuchs, Robyn K.
Abstract:: High impact loading activities such as jumping, performed during childhood is advocated as one preventive method for increasing peak bone mass. Thus, we conducted a randomized intervention to examine the effect of high impact loading on bone mass in 34 pre-pubescent boys and girl over a seven month period. Participants...

Replication of vaccinia virus in the presence of 1,10-phenanthroline

Creator:: ApRoberts, Robyn E.
Abstract:: 1,10-phenanthroline and its non-chelating isomer, 1,7-phenanthroline were used to inhibit the replication of vaccinia virus (VV). Serial passage of VV in the presence of various concentrations of either 1,10-phenanthroline or 1,7-phenanthroline was carried out. No drug resistant mutants were isolated, suggesting that the observed inhibition was due to a cellular...
