Long-term Colonization Of A Subarctic Artificial Reef System In Whittier, Alaska

Creator:: Levy, Charlotte S. and Brown, Eloise J.
Abstract:: Over half of the U.S. coastline is found in Alaska, and the majority of the state’s economic activity occurs along the coast. Increased coastal development poses a potential threat to nearshore habitats in Alaska. The installation of artificial reef (AR) systems can mitigate habitat loss; however, few AR systems have...

Spatial and vertical distribution of the invasive European green crab, Carcinus maenas, in a temperate estuarine system

Creator:: Lundeberg, Christopher A. and Weldon, Taylor
Abstract:: Carcinus maenas is an invasive marine predator. Its generalist feeding strategies make it one of the most effective invaders. Carcinus maenas has invasive populations throughout the world, and was recently introduced to the west coast of North America. This study looks at the abundance and growth of C. maenas in...

Wintertime grazing rates of Antarctic krill, Euphausia superba, along the Northern Antarctic Peninsula

Creator:: Gunther, Lacey, Bernard, Kim, Reiss, Christian, and Dietrich, Kim
Abstract:: Over 70% of the Antarctic krill population exists along the Antarctic Peninsula, a region undergoing rapid climate change. Recent studies have shown a clear correlation between krill recruitment each spring and the timing and coverage of sea ice the winter before, with less sea ice and a shorter duration being...

Colorimetric analysis of creatinine in whole blood and urine in a novel paper/polycaprolactone microfluidic device

Creator:: Pommerenck, Joel, Heist, Christopher A., and Remcho, Vincent T.
Abstract:: A novel approach for the colorimetric detection of creatinine in a paper/polycaprolactone hybrid microfluidic device using alkaline3,5-dinitrobenzoate (DNB) is described. The reaction parameters of reagent concentration, alkalinity, and analysis time are optimized for fast reaction times and high color yield. Microfluidic devices incorporating this assay are designed and fabricated to...

Matrix Metalloproteinases as Plasma Indicators of Bovine Cystic Ovarian Disease

Creator:: Hentze, Kalina F., Younger, Kathryn G., and Menino, Alfred R., Jr.
Abstract:: Cystic ovarian disease (COD) is one of the main causes of infertility in dairy cattle and has a high economic impact on farmers. COD is caused by an endocrine imbalance within the hypothalamic-pituitary-ovarian axis which prevents the mature Graafian follicle from ovulating. The cause at the molecular level is not...

MHC class I molecules and Antigen Presentation

Creator:: Salem, Fares B.
Abstract:: Research in Dolan lab focuses primarily on the adaptive immune system and ways it can be better utilized to eliminate infected or transformed cells. Research focuses on the major histocompatibility (MHC) class I antigen presentation pathway, which plays an important role in alerting the immune system of the presence of...

Kennedy and the Cuban Missile Crisis: The Power of Morality and Moral Perception

Creator:: Therien, Hilary
Abstract:: President Kennedy's construction of civil religion, but more importantly, his morality and moral perception, enabled great success for the United states in the Cuban Missile Crisis and the evasion of nuclear catastrophe.

Carbon Isotope Chemostratigraphic Correlation of the Noonday Formation

Creator:: Morris, Justin
Abstract:: The Marinoan Snowball Earth ended 635 Ma ago during the Neoproterozoic Era, after an interval in which the Earth was completely covered by glaciers. Thawing of these glaciers formed cap carbonates across shallow marine depositional environments. The Noonday Formation is a cap carbonate that formed after the deglaciation of the...

Changes in acceptance of diversity through volunteering with youth with disabilities

Creator:: Porter, Shelby, Hamm, Jessica, Beamer, Jennifer, and Yun, Joonkoo
Abstract:: Background/Purpose: A variety of models have been proposed to understand individuals with disabilities. Although it is important to consider the perspective of disability each model presents, the social model has gained considerable attention. This model explains disability as limitations and restrictions of society and the environment. A subset of the...

Relative Resistance of the Red, Dry, and Rough (RDAR) and Smooth and White (SAW) Morphotypes expressed by Salmonella to a steam blanching treatment

Creator:: Callahan, Selena and Waite-Cusic, Joy
Abstract:: The acquired ability of Salmonella to express varying morphotypes when placed in nutrient-limited conditions is hypothesized to predict increased resistance to food processing interventions. Two of the morphotypes expressed by Salmonella are Red, Dry and Rough (RDAR) and Smooth and White (SAW). Increased resistance is predicted for the RDAR morphotype...

LncRNA regulation in mouse lung tumor from dibenzo[def,p]chrysene induced carcinogenesis in a transplacental Nrf2 knockout mouse model

Creator:: Patel, Karan, You, Hyekyoung, Siddens, Lisbeth, and Williams, David
Abstract:: Dibenzo[def,p]chrysene (DBC) is a highly potent, but less prevalent, environmental carcinogen belonging to a class of compounds known as Polycyclic Aromatic Hydrocarbons (PAHs). They are highly ubiquitous and arise as a byproduct of natural and anthropogenic combustion processes. Previous studies have documented carcinogenic effects upon in utero exposure of PAHs....

Determining the Onset of Reproductive Capacity in Free-Roaming, Unowned Cats

Creator:: Bohrer, Ellie
Abstract:: The purpose of this thesis was to determine if an underlying biological cause exists for the exuberant reproductive success in free-roaming unowned (FRU) cats. The hypothesis for this thesis was that FRU tom and queen cats have reproductively adapted to man-made sterilization efforts by lowering the age at which they...

Quantitative Effects of a Fat Studies Class

Creator:: Bauman, Lia, Pham, Hellen, and Gerber, Madison R.
Abstract:: Fat Studies (FS) is a new interdisciplinary field that addresses oppression based on body weight, shape, and size as it intersects with oppression based on other areas of difference. As such, FS incorporates a weight-neutral approach to health, Health At Every Size® (HAES), that decries weight bias, promotes body self-acceptance...

The Effects of an Inclusive Playgroup on Social Interaction Between Children With and Without Disabilities

Creator:: Inskeep, Kelsey, Ross, Samantha, Twardzik, Erica, Catena, Michele, Ayyagari, Apoorva, Cook, Erika, Winden, Haylee, Fine, Jeremiah, Magnani, Jessica, and Logan, Samuel W.
Abstract:: Being present in an area of play can create a dynamic experience of exploration, movement, and interaction with objects and peers. These are required to foster positive development across cognitive, social, and physical domains (1). Children with disabilities may experience limitations in mobility impacting their early exploration, socialization, and play...

Alternative Exon 3 Inclusion in the Vitamin D Receptor (VDR) Modulates Transcriptional Activity for Target Genes in a Ligand-Independent Manner

Creator:: Cameron, Alex N., Annalora, Andrew, and Marcus, Craig
Abstract:: Xenobiotic exposures may induce alternative splicing in the pre-mRNA of nuclear hormone receptor (NHR) genes, yielding unpredictable patterns of gene expression that may promote adverse drug events and promote environmental disease. Informed by observations in the androgen receptor (AR; class I NHR), whereby alternatively-spliced AR transcripts induce ligand-independent hormone signaling...

The Effects of the Immunity Factor Relish on Aging Phenotypes in Drosophila melanogaster

Creator:: Kumar, Nandita
Abstract:: Aging is a complex biological phenomenon that alters many different physiological processes. Although many age-related phenotypes, such as neurodegeneration, weakening circadian rhythms, and inflammaging, are well-studied, the links between them are not. To elucidate these links we created an inflammation-like state in Drosophila melanogaster by overexpressing Relish (Rel), an NFκB...
