Ovarian protein hormones as biomarkers of fertility in dairy cows – Is it an acceptable model to predict infertility in dairy breeds?

Creator:: Lopez, Ruben
Abstract:: Female dairy cattle are particularly prone to infertility/subfertility with pregnancy rates ranging as low as 27% to a high 40%. On average it takes more than one breeding/insemination event for dairy cattle to become pregnant. This results in a loss of the number of calves a female would have per...

Expression of prolactin in feline mammary adenomas and adenocarcinomas

Creator:: Trummel, Danielle K.
Abstract:: Mammary tumors are the third most common tumor in cats after cutaneous neoplasia and lymphosarcoma. More than 80% of feline mammary tumors are adenocarcinomas, which are similar to human mammary adenocarcinomas in their biologic behavior and histologic characteristics. Despite treatment with radical mastectomy, feline mammary adenocarcinoma is associated with a...

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...

Relative heat sensitivities and the potential for soil solarization to remediate nursery beds infested with Phytophthora spp.

Creator:: Weidman, Clara Suzanne
Abstract:: Infestations of container nursery beds by Phytophthora spp. can be persistent and costly. One method of disinfestation that does not require the use of chemicals is soil solarization, which captures energy from the sun to heat soil and thermally inactivate target pathogens. In laboratory temperature gradient experiments, I investigated the...

Engineering Oriented Protein-Labelled Surfaces

Creator:: Brown, Wesley and Mehl, Ryan
Abstract:: Current protein immobilization techniques lack defined control over protein orientation. Protein orientation is important for making biosensors and biomaterials that are sensitive and efficient and can be crucial for designing some devices such as immunosensors or direct electron transferring biocells. A new method of protein immobilization is proposed that takes...

In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

Creator:: Stocking, Peter
Abstract:: Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...

Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

Creator:: Edwards, Sabrina R.
Abstract:: As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

Stomach Analysis of Top Aquatic Predators in a Headwater Stream Network

Creator:: Ain, Najma
Abstract:: Top predators play important roles in regulating communities and ecosystem processes in freshwater ecosystems. In the headwater stream network, it is crucial to understand the interspecific interaction between multiple predators. In Oregon forested ecosystems, Coastal Giant Salamander (Dicamptodon tenebrosus) and cutthroat trout (Oncorhynchus clarkii) are the top predators in many...

Vegetative effects of RNAi-suppression of the poplar homolog of LEAFY in the field

Creator:: Jacobson, Jeremy
Abstract:: Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...
