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 […]
Cancer and the Immune System: A Study of Cytokine Communication with Macrophages
Charles Daniel Knechtel and Dr. Kim O’Neill, Microbiology Macrophages are a part of the early immune system that interacts with abnormal and foreign cells in your body. They are a non-specific defense system that engulfs foreign cells or stimulates other immune system cells to respond. We know they can play a role in fighting cancer, […]
Exploring Phylogenetic Relationships, Origins of Claws, and Loss of Functional Eyes in Decapod Lobsters (Infraorder Astacidea, Achelata, Glypheidea, Polychelida)
Dohyup Kim and Dr. Keith Crandall, Biology Department Introduction The order Decapoda represents a species-rich and economically important group of crustaceans. Among decapods, lobsters play a huge role of monetary significance, bringing in billions of dollars each year to world fisheries. Understanding the genetic relationships among commercially important lobsters will aid in both fishery and […]
Amantadine Blockage of the Influenza A M2 Proton Transporter
Jared Kelson and Professor David Busath, Department of Physiology and Developmental Biology Main Text The reproduction of influenza A is very closely regulated by the pH levels maintained both in the cytoplasm and in various organelles of a host cell. To accommodate this, the virus provides genetic coding to assemble an M2 transporter which regulates the flow […]
Moving Nucleosomes to Regulate and Maintain Gene Function
Benjamin Jorgensen and Dr. Steven Johnson, Mirco and Molecular Biology Main Text Gene therapy is a technique that uses gene insertions or transgenes to alter and correct genetic mutations that cause hereditary diseases. Gene therapy holds hope in curing diseases such as Cystic Fibrosis and Duchenne Muscular Dystrophy or any disease caused by a recessive […]
A Study on the Effects of Two Delivery Models of Foreign Medical Aid: Short-term Mission Model vs. The Empowerment of Local Medical Professionals
Jayson Johnson and Professor Barbara Lockhart, Excercise Science The main goal of our research was to investigate and gain a better understanding of the perception that local inhabitants of Bolivia have regarding medical aid received in their country. To accomplish this task we surveyed and interviewed those who are most directly affected by this aid, namely […]
“A Rose By Any Other Name…” A Study of Flowering Plant Classification and Species Recognition
Angela Jensen and Dr. Leigh Johnson, Department of Biology Speciation is a scientific “gray area.” Conservation biologists are familiar with the many different proposed definitions for a species, encased in the 10 or so existing species concepts. Individual organisms of the same species are inherently different, possessing a wide variety of characteristics and behaviors. When […]
