Modeling Als-Associated Matrin-3 Toxicity In Yeast, Widad El-Zein Jan 2022

Modeling Als-Associated Matrin-3 Toxicity In Yeast, Widad El-Zein

Browse all Theses and Dissertations

ALS is a neurodegenerative disease characterized by degeneration of upper and lower motor neurons in the brain and spinal cord leading to progressive paralysis and ultimately death. Perturbations in RNA metabolism and RNA binding proteins have emerged as underlying defects in ALS pathogenesis. Matrin-3 is a multifunctional RNA binding protein that has been linked to familial and sporadic ALS. Matrin-3 is normally found in the nucleus, but mutations in the gene cause mislocalization of the protein from the nucleus into the cytoplasm of neuronal cells where it forms protein aggregates. In this study, we show that over-expressing human MATR3 in …


Reconstruction Of Gut Microbiome Via Intermittent Feeding, Kourtney Sprague Jan 2022

Reconstruction Of Gut Microbiome Via Intermittent Feeding, Kourtney Sprague

Browse all Theses and Dissertations

The benefits of intermittent fasting have been studied across many facets of health. It is known that physiologically fasting results in a metabolic switch from liver-derived glucose to adipose cell derived ketones to be used as energy and signaling molecules. Fasting down-regulates inflammation, increases expression of antioxidant defenses, and activates pathways for DNA repair and autophagy. While fasting or intermittent feeding effects on host physiology have been identified, the relationship between fasting and gut microbiome is not as well known. In times of gut rest, resident microbes undergo detoxication and motility, and in times of activity, gut microbes undergo DNA …

Shenandoah Valley Partnership: Growing And Enhancing The Food And Beverage Manufacturing Industry, Justin Williams

Master of Urban and Regional Planning Capstone Projects

This plan analyzes how the Shenandoah Valley Partnership can grow and enhance its food and beverage manufacturing industry. To answer this question, I interviewed and surveyed food and beverage manufacturers to understand their business needs, as well as interviewed service providers to identify their relationships with this industry. The four main results from the plan were:

  • There is a need for more capital for the businesses.

  • There is a labor shortage in the industry.

  • The Shenandoah Valley has an excellent distribution location.

  • The industry has a poor relationship with the region’s service providers.

The plan outlines recommendations on how institutions …

The City of Richmond is beginning the process of creating a composting program for the first time in the city’s history. It is part of a cross-departmental collaborative plan to divert food waste from the landfill and into a new composting program. The Office of sustainability is in the process of drafting the RVAGreen 2050 Climate and Equity Master Plan for Richmond, which includes an ambitious zero-waste goal. In order to accomplish this future goal, the city must begin setting up the infrastructure to begin diverting waste from the landfill.

The purpose of the Community Composting Initiative Plan is to …


Getting To Know You: Relationship Formation Across Development In Octodon Degus, Amber Lynn Thatcher Jan 2022

Getting To Know You: Relationship Formation Across Development In Octodon Degus, Amber Lynn Thatcher

Graduate Student Theses, Dissertations, & Professional Papers

Social relationships are a necessary part of group formation and cohesion across many animal species and can increase the health and fitness of the individuals involved. These benefits are seen across the lifespan, although the exact advantages and functions differ across developmental stages. Our current understanding of how relationships are formed and maintained is incomplete. Previous findings suggest that a measure of stability may be a useful method for understanding how relationships are formed and how this process may differ across development. The goal of this dissertation is to investigate the variability of social interactions over time and how it …


The Surprising Virtues Of Data Loyalty, Woodrow Hartzog, Neil Richards Jan 2022

The Surprising Virtues Of Data Loyalty, Woodrow Hartzog, Neil Richards

Emory Law Journal

Lawmakers in the United States and Europe are seriously considering imposing duties of data loyalty that implement ideas from privacy law scholarship, but critics claim such duties are unnecessary, unworkable, overly individualistic, and indeterminately vague. This paper takes those criticisms seriously, and its analysis of them reveals that duties of data loyalty have surprising virtues. Loyalty, it turns out, can support collective well-being by embracing privacy’s relational turn; it can be a powerful state of mind for reenergizing privacy reform; it prioritizes human values rather than potentially empty formalism; and it offers solutions that are flexible and clear rather than …

The City Of Nightmares: Occultism, Ecstasy, And The Literature Of Late-Victorian London, Sophie Labenski Jan 2022

The City Of Nightmares: Occultism, Ecstasy, And The Literature Of Late-Victorian London, Sophie Labenski

Comparative Literature M.A. Essays

While the relationship between Gothic motifs and anxieties about transgressive sexuality at the end of the 19th century is well understood, most of the scholarship written on this topic takes the idea of the supernatural for granted, or sees it as a way of establishing the links between monstrosity and sexuality. In this essay

I turn to the work of Arthur Machen in order to recontextualize the supernatural aspects of the late-Victorian Gothic literature in regard to the forms of credulity that inform the occult. While texts like Robert Louis Stevenson’s The Strange Case of Dr. Jekyll and Mr. Hyde …


Out Of The Gutter, Into The Gram: A Comical Message And A Digital Medium, Tala Majzoub Jan 2022

Out Of The Gutter, Into The Gram: A Comical Message And A Digital Medium, Tala Majzoub

Comparative Literature M.A. Essays

By analyzing three different comics on Instagram by the Lebanese political cartoonist, the Art of Boo, this essay argues that comics generate political meaning through emulating the medium of Instagram on the one hand, and by inviting the audience to become active participants on the other. Although a lot has been written about digital activism and political cartoons in the Arab world, little has been theorized about what makes this form of political artistic expression and dissent powerful on digital platforms. By drawing on Scott McCloud’s Understanding Comics, this essay demonstrates that the medium of comics operates as a …


Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich Jan 2022

Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich

Harold W. Manter Laboratory of Parasitology: Library Materials

Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centered on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem. Civilization, and perhaps even the fate of our species, is utterly dependent on that ecosystem’s proper functioning, which society is increasingly degrading. The crisis seems rooted in three factors. First, relatively few people globally are aware of its existence. Second, most people who …


Male Mastodon Landscape Use Changed With Maturation (Late Pleistocene, North America), Joshua H. Miller, Daniel C. Fisher, Brooke E. Crowley, Ross Secord, Bledar A. Konomi Jan 2022

Male Mastodon Landscape Use Changed With Maturation (Late Pleistocene, North America), Joshua H. Miller, Daniel C. Fisher, Brooke E. Crowley, Ross Secord, Bledar A. Konomi

Department of Earth and Atmospheric Sciences: Faculty Publications

Under harsh Pleistocene climates, migration and other forms of seasonally patterned landscape use were likely critical for reproductive success of mastodons (Mammut americanum) and other megafauna. However, little is known about how their geographic ranges and mobility fluctuated seasonally or changed with sexual maturity. We used a spatially explicit movement model that coupled strontium and oxygen isotopes from two serially sampled intervals (5+ adolescent years and 3+ adult years) in a male mastodon tusk to test for changes in landscape use associated with maturation and reproductive phenology. The mastodon’s early adolescent home range was geographically restricted, with no evidence of …


Death Scene Insect Succession In Nebraska: A Guidebook, Erin Bauer, Larry Barksdale, Emma Sidel, Justine Laviolette Jan 2022

Death Scene Insect Succession In Nebraska: A Guidebook, Erin Bauer, Larry Barksdale, Emma Sidel, Justine Laviolette

Department of Entomology: Faculty Publications

Insect behavior can be helpful to law enforcement in determining time of death, manner of death, location, and environment related to human or other animal victims found at a death scene. They may also provide clues about other aspects associated with an investigation (i.e., fly specks, suspect DNA). The study of how insects and related arthropods can aid in legal investigations is known as forensic entomology. Although this includes both civil applications, such as urban (i.e., maggots in mortuaries or insect structural damage) or stored product (i.e., illness from food contamination) entomology, this manual focuses on criminal applications, such as …

Colostrum contains all essential nutrients for the neonate during the first days of life, with impacts that continue far beyond these first days. Bovine colostrum has been used for human consumption due to the high concentrations of bioactive proteins, vitamins, minerals, growth factors, as well as free and conjugated oligosaccharides. Processes involved in the preparation of bovine colostrum for human consumption play a pivotal role in preserving and maintaining the activity of the bioactive molecules. As bovine colostrum is a multifunctional food that offers a myriad of benefits for human health, assessing the main processes used in preparing it with …

Department of Food Science and Technology: Faculty Publications

Predicting phenotype from genotype is a central challenge in biology. By understanding genomic information to predict and improve traits, scientists can address the challenges and opportunities of achieving sustainable genetic improvement of complex, economically important traits in agriculturally relevant species. Converting the enormous, recent technical advances in all areas of genomics and phenomics into sustained and ecologically responsible improvements in food and fuel production is complex. It will require engaging agricultural genome to phenome (G2P) experts, drawing from a broad community, including crop and livestock scientists and essential integrative disciplines (e.g., engineers, economists, data and social scientists). To achieve this …

Nebraska Center for Virology: Faculty Publications

Influenza A virus of swine (IAV-S) is an economically important swine pathogen. The IAV-S hemagglutinin (HA) surface protein is the main target for vaccine development. In this study, we evaluated the feasibility of using the recombinant tri-segmented Pichinde virus (rPICV) as a viral vector to deliver HA antigen to protect pigs against IAV-S challenge. Four groups of weaned pigs (T01–T04) were included in the study. T01 was injected with PBS to serve as a non-vaccinated control. T02 was inoculated with rPICV expressing green fluorescence protein (rPICV-GFP). T03 was vaccinated with rPICV expressing the HA antigen of the IAV-S H3N2 strain …

The ability to represent approximate quantities appears to be phylogenetically widespread, but the selective pressures and proximate mechanisms favouring this ability remain unknown. We analysed quantity discrimination data from 672 subjects across 33 bird and mammal species, using a novel Bayesian model that combined phylogenetic regression with a model of number psychophysics and random effect components. This allowed us to combine data from 49 studies and calculate the Weber fraction (a measure of quantity representation precision) for each species. We then examined which cognitive, socioecological and biological factors were related to variance in Weber fraction. We found contributions of phylogeny …


Evaluation Of Ivermectin Antiviral Activity Against Avian Infectious Bronchitis Virus Using A Chicken Embryo Model, Donald L. Reynolds, E. Barry Simpson Jan 2022

Evaluation Of Ivermectin Antiviral Activity Against Avian Infectious Bronchitis Virus Using A Chicken Embryo Model, Donald L. Reynolds, E. Barry Simpson

School of Veterinary and Biomedical Sciences: Faculty Publications

Ivermectin is widely used in both animals and humans as an FDA-approved parasiticide. Ivermectin has also been reported to have antiviral activity against several viruses including coronaviruses. There are reports that indicate ivermectin may have some role in diminishing the disease caused by SARS-CoV-2, but the evidence is inconclusive. The objective of this study was to determine if ivermectin was efficacious in inhibiting avian infectious bronchitis virus (IBV, a coronavirus) replication in chicken embryos. Briefly, our approach was to use the Massachusetts vaccine strain of IBV in combination with various doses of ivermectin and then inoculate these preparations into chicken …

Heaton, Brian L. Vander Ley, Carolina Herrera, Heinrich Bollwein, Derek M. Bickhart, Benjamin D. Rosen, Hubert Pausch

School of Veterinary and Biomedical Sciences: Faculty Publications

Advantages of pangenomes over linear reference assemblies for genome research have recently been established. However, potential effects of sequence platform and assembly approach, or of combining assemblies created by different approaches, on pangenome construction have not been investigated. Here we generate haplotype-resolved assemblies from the offspring of three bovine trios representing increasing levels of heterozygosity that each demonstrate a substantial improvement in contiguity, completeness, and accuracy over the current Bos taurus reference genome. Diploid coverage as low as 20x for HiFi or 60x for ONT is sufficient to produce two haplotype-resolved assemblies meeting standards set by the Vertebrate Genomes Project. …

School of Veterinary and Biomedical Sciences: Faculty Publications

In the last 15 years, crustacean fisheries have experienced billions of dollars in economic losses, primarily due to viral diseases caused by such pathogens as white spot syndrome virus (WSSV) in the Pacific white shrimp Litopenaeus vannamei and Asian tiger shrimp Penaeus monodon. To date, no effective measures are available to prevent or control disease outbreaks in these animals, despite their economic importance. Recently, double-stranded RNA-based vaccines have been shown to provide specific and robust protection against WSSV infection in cultured shrimp. However, the limited stability of double-stranded RNA is the most significant hurdle for the field application of these …

Pilot-Scale Spinning And Sucrose-Tetra-Aldehydes-Crosslinking Of Feather-Derived Protein Fibers With Improved Mechanical Properties And Water Resistance, Bingnan Mu, Faqrul Hassan, Qianmei Wu, Yiqi Yang

Department of Textiles, Merchandising and Fashion Design: Faculty Publications

Pliable and water-resistant protein fibers from feathers were developed via continuous one-step spinning and crosslinking using sucrose-tetra-aldehydes. Though flexible protein fibers from feathers were developed, poor wet stability and low tenacity still limit the large and high-end applications of feather-derived fibers. Despite that saccharide aldehydes are considered as an efficient and sustainable crosslinker, substantial concerns such as generation of formaldehyde, high consumption of modifiers, loss of mechanical properties, yellowing, and decline in dyeability of fibers, exist after crosslinking. In this work, we controlled structures of crosslinkers and incorporated disaccharide-tetra-aldehydes into a continuous wet-spinning line. No formaldehyde was generated in the …

Department of Agronomy and Horticulture: Faculty Publications

Dung excreted by cattle composes a significant portion of the nutrient inputs in a grazed ecosystem and can have wide-ranging effects on soil properties and vegetation. However, little research has been conducted on the nutrient dynamics of excreted dung in situ that has not been disturbed prior to field sampling. In this study, we analyzed 294 dung pats (1–24 days old) collected from a Nebraska Sandhills meadow to determine water-extractable organic carbon (WEOC), water-extractable nitrogen (WEN), water-extractable phosphorus (WEP), and percent dry matter (DM) changes over time. In addition, we investigated if sample handling - frozen storage – and the …
