Tristan McKnight and Dr. C. Riley Nelson, Biology Department The last few decades have seen an explosion of agricultural expansion and mining in Mongolia. These developments—loosely regulated at best—strain the ecological health of the steppe environment with pollution and overgrazing. Robber flies (Fig. 1) are small predators common in most terrestrial ecosystems that may play […]
Function of Novel Nuclear Bone Morphogenetic Protein 2 in regulating Inositol 1,4,5-triphosphate Receptor 1 Expression
Broc McCune and Dr. Laura Bridgewater, Microbiology and Molecular Biology Main Text Bone morphogenetic protein 2 (Bmp2) is a well-characterized secreted transforming growth factor. Researchers in the lab of Dr. Laura Bridgewater, Brigham Young University, discovered a novel nuclear variant of Bmp2 (nBmp2)1. Preliminary data indicates that mice not expressing nBmp2 have difficulty regulating intracellular […]
The Cerebral Cortex as an Effect Site for Anesthetic Induced Unconsciousness
Ryan Martin and Professor David Busath, Physiology and Developmental Biology Main Text General anesthetics are widely used today in medicine. Their molecular mechanisms however, still remain a mystery. For centuries, general anesthetics were thought to be “drugs without receptors” because of the lack of knowledge about their mechanism of action (Hemmings, et al., 2005). While some advances […]
Phylogeography and Population Structure of Scottnema lindsayae
Mac Martin with Dr. Byron Adams, Department of Biology Glaciologists have suggested that because of the extent of the ice sheets during the last glacial maximum (LGM) in Antarctica no terrestrial species could have survived these harsh conditions. However, substantial evidence suggests that some invertebrate species did indeed survive the LGM. We hypothesize that S. […]
Potential Synergism between Antioxidants found in Blueberries (Vaccinium Cyanococcus)
Richard Low and Dr. Tory Parker, Department of Nutrition, Dietetics, and Food Science Main Text According to a review by Battino et al. (2009), blueberry consumption can regulate blood pressure, inhibit cancer growth, and improve cardiovascular health by preventing plaque buildup in the arteries. Naturally occurring antioxidants found in fruits and vegetables that are thought […]
Destabilization of the Medial Meniscus: A Non-Genetic Approach to Inducing Osteoarthritis in Mice
Christopher Stockdale, Joshua Lloyd, and Dr. Robert E. Seegmiller, Physiology and Developmental Biology Osteoarthritis (OA) is a common disease that causes discomfort and pain due to the degradation of the articular cartilage found on the surface of bones within the body’s joints. A properly functioning joint has a strong network of articular cartilage that can […]
The Contribution of CCR9 to the Homing, Migration, and Accumulation of IgA Antibody Secreting Cells in Mouse Salivary Glands
Susanne Linderman with Dr. Eric Wilson, Microbiology and Molecular Biology IgA is the most common antibody isotype involved in the immune system’s defense of mucosal membranes. In order to migrate and accumulate at these sites, IgA antibody secreting cells rely on chemokines. These chemokines, which are proteins differentially secreted in different tissues, bind to chemokine […]
What can Phylogeographic Breaks in the Livebearer Poeciliopsis Turrubarensis tell us about Fish Community Boundaries in Western Costa Rica?
April Larson and Dr. Jerald B. Johnson, Biology One active area of study in ecology, termed biogeography, is the determination of how communities are formed. A basic knowledge of what factors have shaped the formation of ecological communities leads to greater understanding of a system as a whole and specific species interactions. One possible factor […]
Assessing the Splicing Variants of the Interferon Regulatory Factor 5 Risk Haplotype
Jared Lambert and Dr. Brian Poole, Life Sciences Introduction Systemic lupus erythematosus (SLE) is an autoimmune disease which commences from the immune system producing antibodies which target the body’s own tissues and cells. There are various factors thought to be involved in the development of SLE. In this study I assessed how the splicing variants […]
Genetic Investigation of the Pathology of Ustilago bullata
Erin Ladle and Dr. Jeff Maughan, Plant and Wildlife Sciences Main Text Bromus tectorum L., commonly known as cheatgrass, is an invasive annual grass species that dominates millions of hectares of land in the Great Basin area, in the western United States.1 The widespread invasion of cheatgrass has increased fire incidence in some areas of […]
