Anson Call and Dr. Samuel St. Clair, Department of Plant and Wildlife Science Introduction Clonal plants are important contributors to natural environments and can have disproportionate effects on ecosystem function. In the mountain west, the clonal species Populus tremuloides (quaking aspen) is critical in helping to regulate ecosystem function; healthy aspen stands support a diverse […]
Understanding the Role of Estrogen in the Mucosal Immune Response
Youna Choi and Dr. Eric Wilson, Microbiology and Molecualr Biology Introduction Most antigens (foreign substances) enter an organism via mucosal surfaces. Thus, understanding the mechanisms involved in immune protection at these surfaces is of paramount importance. Immune responses are highly dependent on homing mechanisms responsible for directing lymphocyte (white blood cell) migration and accumulation at […]
Anatomical Variation of the Porcine Recurrent Laryngeal Nerve
Marc Christensen and Dr. Jonathan Wisco, Department of Physiology and Developmental Biology Introduction Selective reinnervation of the posterior cricoarytenoid muscle (PCA), accomplished by anastomosis of a transected recurrent laryngeal nerve (RLN) with the phrenic nerve, is the best treatment for vocal cord paralysis and RLN compromise. However, anatomical variation of the RLN in human patients […]
Effect of harvester ants on invasive and native plant establishment on disturbed sites in Rush Valley, Utah
Amy Clark and Samuel B. St. CLair, Plant and Wildlife Science Department Introduction Invasive species pose a serious threat to earth’s ecosystems. This is a problem especially in the arid west where millions of acres of Great Basin shrubland have become dominated by invasive weeds such as cheatgrass and halogeton following disturbances like fire. Both […]
Genetic Variation within Cotton Tissues
Kimberly Clemons and Dr. Joshua Udall, Plant and Wildlife Sciences Introduction The purpose of the copy number variation (CNV) project was to determine if there is a variation in the DNA content between tissue types of Gossypium hirsutum and Gossympium barbadense. Specifically if the cotton fiber cells contain CNV that contribute to the increased output […]
Social Cognitive Predictors of Residential Radon Testing and Mitigation
Siena Davis and Dr. James Johnston, Health Science Introduction In the U.S., exposure to radon gas (222Rn) is the second leading cause of lung cancer after tobacco smoke.(1) 222Rn is a naturally occurring environmental carcinogen produced during the radioactive decay of uranium-238, which is found in many soils throughout the U.S.(2) Because 222Rn is a […]
Mapping Interaction Through Compensatory PhoU Mutants in Escherichia Coli
Tanner Dean and William McCleary, MMBIO Introduction The purpose of this experiment was to identify the physical interaction site between two proteins in Escherichia Coli. These two proteins, PhoU and PhoR, are two proteins involved in Phosphate signal transduction. When these two proteins are mutated, so they no longer interact, the pathway is broken and […]
Mapping the Trigeminal Nerve
Kinnison Edmunds and Dr. Jonathan Wisco, Department of Physiology and Developmental Biology Introduction The goal of my project was to create a data-driven, three-dimensional map of the human trigeminal nerve from the trigeminal ganglion to the ends of its major pathways throughout the face and head. The purpose was to test conventional wisdom regarding the […]
Microarchitectural Analysis of the Ulnar Collateral Ligament to Inform its Reconstruction
Jakob Gamboa and Dr. Jonathan Wisco, Physiology and Developmental Biology Ligaments are specialized connective tissues that stabilize the different synovial joints found in the body. Ligaments consist of fibroblast cells surrounded by a framework of dense fibrous bands of collagen, which anchor to bones to provide support and elasticity. Their varying biomechanical functions in different […]
Customizing 3D models from MRI data: Creating educational anatomy models of neurologic disease
Brett Gardiner and Dr. Jon Wisco, Department of Physiology and Developmental Biology Introduction Neuroanatomy lab specimens are limited to cadaver availability and inconsistently demonstrate variations confronted in pathology. Using rapid prototyping (RP) technology to create 3D models from segmented MRI data offers distinct benefits to medical education. An efficient and replicable procedure for customizing these […]
