The Effects Of Alcohol On The Developing Drosophila Nervous System, Erica E. Hassoun

The Cardinal Edge

Ethanol is the most common human teratogen, contributing to fetal alcohol syndrome (FAS) when effects are the most severe. Key effects of fetal alcohol syndrome are observed in the nervous system. The high prevalence of prenatal alcohol exposure necessitates novel treatment and prevention methods. However, ethical issues prevent researching humans in utero. For this reason, the fruit fly Drosophila melanogaster has emerged as a model organism for studying FAS. Because Drosophila is a small and non-placental organism, its environment can be easily controlled, allowing for specific doses and time periods of ethanol exposure to be studied. This review discusses findings …

The Motion Aftereffect: Mechanisms And Variants, Erica E. Hassoun

The Cardinal Edge

The motion aftereffect causes a visual stimulus to undergo apparent motion. An adapting stimulus, which moves in a specific direction, adapts motion-responsive neurons in the middle temporal area (V5) to that direction of motion. Viewing a second stimulus, a test stimulus, produces apparent motion in the direction opposite that of the initial stimulus. Neural networks involved in attention and working memory are also implicated in the motion aftereffect. There is still little known regarding the mechanisms of the motion aftereffect, despite extensive documentation in the literature. This review discusses established knowledge of the motion aftereffect, focusing primarily on the middle …

Sexual Health Misinformation And Potential Interventions Among Youth On Social Media, Jahnavi Sunkara

The Cardinal Edge

With the rise of the internet and social media, many adolescents and young adults have turned to the internet and social media for sexual health information. However, this can be problematic because sexual health misinformation on social media utilizes a variety of techniques to quickly disseminate and retain that misinformation in users. Historically, the spread of sexual health misinformation has specifically negatively impacted adolescents and young adults regarding two sexual health topics: contraceptives and HPV vaccination. Current evidence demonstrates that a combination of corrections and inoculation would be effective against general health misinformation. However, there is a lack of research …

Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler

The Cardinal Edge

This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …

Evolution Or Revolution: The Cultural Development Of American Conservationism From U.S. Grant To Theodore Roosevelt, Scott W. Randolph

The Cardinal Edge

This paper seeks to frame an understanding of the legal protections for American wilderness as a result of various cultural and intellectual movements in the United States during the middle to late nineteenth century. The paper considers the rise of scientific analysis of the American West, the humane movement, romanticizing of the West, and increased federal power after the Civil War as principal contributions to the development of conservationism. The paper also considers conservation policies adopted by post-Civil War U.S. presidents from U. S. Grant to Theodore Roosevelt.

The Effects Of Ppal-1 In Arabidopsis Gamete Development, Amanda J White, Susana Perez-Martinez, Mark P. Running

The Cardinal Edge

Prenylation is a type of post-translational modification in which a 15- or 20-carbon lipid is added to the carboxyl (C) terminus of the protein. Arabidopsis thaliana contains the PROTEIN PRENYLTRANSFERASE ALPHA SUBUNIT-LIKE (PPAL) gene, which encodes a protein with homology to the α-subunits of the three known prenylation enzymes, PFT, PGGT, and Rab-GGT. We previously identified two mutations in PPAL, one of which is ppal-1, which contains a T-DNA insertion in the fourth intron. We have previously observed that self-fertilizing heterozygous ppal-1 plants produce progeny in which homozygous ppal-1 is underrepresented. This project attempts to ascertain …

Identification Of The Biological Function Of Rab-Ggt Β-Subunits By Reverse Techniques, Briana L. Seibert, Hyun Jin Jung, Mark P. Running

The Cardinal Edge

Abstract

Protein prenylation is a post-translational process where lipids are added to carboxyl end groups of amino acids, which allows proteins to function properly in the eukaryotic cell. The job of prenylation is to target certain proteins to specific membranes and promote desirable protein-protein interactions. In our study we used reverse genetics techniques to investigate the function of protein prenylation in plant development. To discern the function of protein prenylation, we examined the phenotypic changes caused by specific gene disruptions. In this study the model organism Physcomitrella patens (moss) is utilized due to its simple structure, limited quantities of tissues …

Protein prenylation is the addition of a 15 or 20 carbon lipid to a cysteine near carboxyl terminus of target proteins. Prentlyation increases hydrophobicity, which facilitates membrane associations and protein-protein interaction. Protein prenylation is generally conserved among eukaryotes, and mutations in genes that carry out prenylation are lethal in animals and yeast. In plants prenylation mutations are not always lethal, but they do affect development, disease resistance, biofuel production, and drought response, among other processes of …

Stable Isotopes Used To Infer Trophic Position Of Green Turtles (Chelonia Mydas) From Dry Tortugas National Park, Gulf Of Mexico, United States, David C. Roche, Michael S. Cherkiss, Brian J. Smith, Derek A. Burkholder, Kristen M. Hart

Marine & Environmental Sciences Faculty Articles

Evaluating resource use patterns for imperiled species is critical for understanding what supports their populations. Here we established stable isotope (δ¹³C, δ¹⁵N) values for the endangered green sea turtle (Chelonia mydas) population found within the boundaries of Dry Tortugas National Park (DRTO), south Florida, USA. There is little gene flow between turtles sampled at DRTO and in other rookeries in Florida, underscoring the need to study this distinct population. Between 2008 and 2015 we collected multiple sample types (skin [homogenized epidermis/dermis], whole blood, red blood cells, plasma, carapace) from 151 unique green turtles, including …

However, for 2018 Gardner-Webb University alumnus Luke Gazak, a forester with the National Wild Turkey Federation (NWTF), the job is much more than that. His role in Chadron, Neb., is a cooperative position created and funded by the NWTF, Nebraska Game & Parks Commission (NGPC), Nebraska Forest Service (NFS), the U.S Forest Service (USFS), and the Nebraska Environmental Trust (NET) grant.

The Ghost Of Hosts Past: Impacts Of Host Extinction On Parasite Specificity, Maxwell J. Farrell, Andrew W. Park, Clayton E. Cressler, Tad Dallas, Shan Huang, Nicole Mideo, Ignacio Morales-Castilla, T. Jonathan Davies, Patrick Stephens

Faculty Publications

A growing body of research is focused on the extinction of parasite species in response to host endangerment and declines. Beyond the loss of parasite species richness, host extinction can impact apparent parasite host specificity, as measured by host richness or the phylogenetic distances among hosts. Such impacts on the distribution of parasites across the host phylogeny can have knock-on effects that may reshape the adaptation of both hosts and parasites, ultimately shifting the evolutionary landscape underlying the potential for emergence and the evolution of virulence across hosts. Here, we examine how the reshaping of host phylogenies through extinction may …

Mechanical And Material Characterization Of Advanced Materials For Tissue Regeneration, Bailey Kylara Ricketts Jackson

Theses and Dissertations

In natural disasters and military deployment operations, injury to long bone can cause extensive damage and be difficult to treat and heal quickly. Explosive devices and trauma often produce long-bone (>2-cm length) wounds that are more complicated than common fractures. Due to the size and complexity of these injuries, they can be difficult to treat in a battlefield environment and take a long time to heal completely and properly. Even after the long healing period, these injuries often require rehabilitation to strengthen the muscles that have weakened in the wounded limb. For military applications especially, these effects can put …

Selenium Probes For The Detection Of Thioredoxin Reductase Activity, Tendai Joseph Mafireyi

Dissertations and Theses

The identification and quantification of proteins and enzymatic activity in living tissues frequently requires the use of invasive procedures such as biopsy. These techniques can inhibit measurements of protein levels in real-time, and the disruption of tissue can lead to the loss of important information concerning the spatial distribution and differential activities in various cell types. The use of small organic fluorescent probes that rely on activation or accumulation within a tissue embody robust methods of detection that address these issues. This dissertation describes the design, synthesis and evaluation of fluorescent probes that can detect the enzyme thioredoxin reductase (TrxR). …

Biosecurity Research Articles

The virulence of 57 Australian isolates of Pyrenophora tritici-repentis (Ptr), a necrotrophic fungal pathogen responsible for the major wheat disease tan spot, was assessed through plant infection assays. Isolates collected from the northern, southern, and western wheat-cropping regions of Australia were evaluated against 16 Australian bread wheat cultivars under controlled growth conditions. Following infection, the wheat panel displayed varying disease symptoms ranging from tiny necrotic specks to spreading chlorotic and necrotic lesions. Analysis of variance indicated that the wheat cultivar exhibited a greater effect on the disease response, explaining 62.7% of the variation, in comparison to the isolate …
