Changes In Environmental Conditions Affect The Two Isoforms Of Snap-25 Differently, Joseph Jackson, Dixon J. Woodbury, Tanner M. Blocker, Samuel W. Shumway, Jarom S. Sumsion, Thomas Weed, Jason Carlson, Nathan Mumford, Ryan Poland

Library/Life Sciences Undergraduate Poster Competition 2024

In the brain, neurons communicate via releasing and detecting neurotransmitters. Release occurs through exocytosis, following fusion of synaptic vesicles to neuronal cell membranes. This process is driven by formation of a dynamic quaternary protein structure known as the SNARE complex. SNAP-25 contributes two alpha helical domains to this complex. Neurons express SNAP-25 in two distinct isoforms, SNAP-25A (25A) and SNAP-25B (25B). These two isoforms vary by only 9 amino acids and are expressed differently depending on brain region and the developmental stage of the neuron [1]. The primary structures of 25A and 25B and their effect on SNARE complex formation …

Role Models V. Knowledge: Should We Use Different Evolution Teaching Strategies For Students With Varying Levels Of Scientific Reasoning Skills?, Kenny Harrington, Jamie Jensen

Library/Life Sciences Undergraduate Poster Competition 2024

What We KNOW:

Learning the mechanisms of evolution (sometimes), i.e., Knowledge…

and having a Role Model present both serve to increase evolution acceptance.

Some have suggested that scientific reasoning ability predicts evolution acceptance, while others refute this.

We HYPOTHESIZE that students’ scientific reasoning ability moderates the effect of Knowledge on evolution acceptance. We PREDICT that those with higher reasoning skills will find Knowledge more compelling than Role Models.

Adapting The Auxin-Inducible Degron (Aid) System To The Zebrafish Model Organism, Dennis Li

Library/Life Sciences Undergraduate Poster Competition 2024

The Auxin Inducible Degron (AID) system is a conditional and reversible protein degradation system naturally occurring in plants. In the presence of the hormone Auxin, the AID tagged proteins are recruited into the plant’s E3 ubiquitin ligase machinery, ubiquitinated, and marked for degradation1. To adapt the AID system to the zebrafish model organism, our lab generated lines co-expressing Arabidopsis Thaliana plant TIR1 protein and GFP tagged with AID (GFP-AID) in superficially-located mechanosensory hair cells (HC) of the lateral line system and in spinal cord neurons found deeper in the body. Upon auxin application, GFP-AID expressed in the superficial HCs was …

Fishing For Neurocircuitry: Identifying Multi-Sensory Integrating Neurons In The Optic Tectum Of Zebrafish, Suehelen A. Garcia, Adeline Hamilton, Karianne Jex, Erika C. Marks, Jordan T. Yorgason, Tracianne B. Neilsen, Arminda Suli

Library/Life Sciences Undergraduate Poster Competition 2024

The superior colliculus (SC) is a mammalian midbrain structure involved in multimodal sensory integration and is implicated to have a role in neurodevelopmental disorders. Although the presence of multisensory integrating neurons (MINs) in the SC has been well documented by electrophysiology techniques, little is known about their morphological or molecular characterization. To identify and study MINs, we utilized SC’s non-mammalian homologous structure–the optic tectum (OT)–in the genetically tractable model organism zebrafish. In this process, we generated transgenic lines that allowed for fluorescent detection of neuronal activity by expressing the genetically engineered calcium indicators: cytoRGECO and H2B-jRGECO1a, respectively in mechanosensory hair …

Exploring Changes In Micro-Invertebrate Species Composition In Rock Pools Of The Colorado Plateau, Hamer Goolsby, Russell Rader, Sara Schenk

Library/Life Sciences Undergraduate Poster Competition 2024

• In ecology, desert rock pools form an ideal model ecosystem. These typically isolated pools a small enough that a researcher can observe the entire system and record everything going into and out of this aquatic system. This removes one of the most important confounding factors for observational studies in ecology, making rock pools an important system to understand.
• The rock pools of the Colorado Plateau in the western United States consist of three main types: 1) scoured pools in temporary stream channels that violently flood during rainstorms (locally called Tinajas), 2) shorthydroperiod pools which are shallow depressions (< 0.6 m deep) that thaw in March and dry by the end of April , and 3) long hydroperiod pools which are deep pools (1-3 m) that thaw in March and persist until June.
• Meiofauna (animals …

Tree Damage Patterning In Alaskan Forests, Emma Barton, Richard Gill, Haden Penrod

Library/Life Sciences Undergraduate Poster Competition 2024

• Tree defoliation (from insect parasites) is not abnormal in the densely forested areas of Alaska, but large outbreak events in recent years have led to cause for alarm.

• To better understand the factors affecting defoliation, we used remote sensing and GIS (geospatial information system) technologies to look at mortality spatial patterns across Hemlock and Spruce forests in southeast Alaska.

• Elevation and proximity to water as well as other factors were considered in determining the impacts of outbreak events due to evidence that changes in landscape can alter parasitism behaviors (Roland & Taylor, 1997).

Theranostic Approaches To Treat Synovial Sarcoma, Machenzie Burr, Jared Barrott, Jeffrey Okojie, Delaney Anderson, Peyton Worley, Jack Davis, Bridger Kearns, Melanie I'Anson-Holton

Library/Life Sciences Undergraduate Poster Competition 2024

Synovial sarcomas (SS) are rare soft tissue cancers that are found beside bone in children and adolescents. Currently, the prognosis for these diseases are low, as diagnostic and treatment options are limited due to the rarity of the disease. With high rates of metastasis, treatment options for these diseases become further limited to primarily radiation and chemotherapies. These therapies have limited specificity in their mechanisms, causing severe side effects in patients. This work examined alternative options for synovial sarcoma theranostic approaches, specifically using immunoconjugates for Oncostatin M Receptors (OSMR). This receptor was chosen due to the high rate of expression …

The Heteronomy Of Flesh: A Minor Jurisprudence Of The Use Of The Human Dead And Tissues, Joshua David Michael Shaw

PhD Dissertations

The dissertation addresses historical and contemporary legal literatures—generally literatures that have not succeeded in becoming convention (Peter Goodrich)—that assert or rely on the human body’s “jurisgenerativity” (Robert Cover) to evaluate and determine what should be lawfully done with the human dead or tissues. These literatures demonstrate the limits of doctrinal legal methods and conventional jurisprudence which ordinarily deploy concepts of property or personhood. Instead of property or personhood, these literatures require the jurisprudent to attune to the heteronomy of flesh, a law engendered in the materiality of the body decomposing, cut into parts, or as fragments falling away from the …

A Quantum Logic Gate In The Dna Deoxyribose Moiety, F. Matthew Mihelic

Faculty Publications

The deoxyribose moiety of a nucleotide in the DNA molecule can act as a quantumlogic gate, in which the enantiomeric shift between the C2-endo and C3-endo conformations of each nucleotide, occurs within a logically and thermodynamically reversible situation of electron spin qubits, that are coherently held within the topologically insulating DNA crystalline nanostructure, and that are coherently conducted along the delocalized electrons of the pi-stacked nucleotide base pairs. The enantiomeric symmetry between the C2-endo and C3-endo conformations is logically and thermodynamically reversible because it functions as a symmetry-breaking Szilard engine that is effectively built out of the physicality of the …
