Relationship Between Prodigiosin Production And Batrachochytrium Dendrobatidis Metabolite Concentration, Nautica Ek Hagg

Honors Thesis

Batrachochytrium dendrobatidis (Bd) is a pathogenic fungus that has been causing extirpations of amphibian species across the globe. The microbiome on the skin of amphibians is known to be a key factor in infection dynamics. It has been established that one species of cutaneous bacteria, Serratia marcescens, and a secondary metabolite with antifungal properties it produces, prodigiosin, has shown a promising ability to decrease the growth of Bd. However, when Serratia marcescens is grown in the same media with added metabolites produced by Bd, there is an observed decrease in the production of the bacteria’s protective metabolite, prodigiosin. This experiment …

Wandering From The River: On- And Off-River Abundance Of Interior Least Terns Along The 59-Mile Reach Of The Missouri National Recreational River, Zoe D. Donelan

Honors Thesis

The Interior Least Tern, a summer nesting species native to the sandbars of the Missouri River, faces significant loss of foraging habitat and forage fish populations as a result of modern river regulation. Alternative foraging sites may be located several kilometers from tern nesting colonies at either on-river or off-river wetland sites. To understand how Least Terns use available foraging habitat, we conducted population surveys along the 59-mile reach of the Missouri National Recreational River (MNRR) in Southeastern South Dakota. We conducted land-based surveys at nine on-river public-access sites along the Missouri River and 12 off-river wetland sites within 30 …

Relationship Between Maternal Plasma Retinol And Provitamin A Carotenoids With Fetal And Infant Kidney Development, Anum Akbar

Theses & Dissertations

Vitamin A plays a critical role in fetal organ development. Studies suggest that maternal vitamin A deficiency affects fetal nephron numbers, potentially leading to smaller kidney sizes and an increased risk of chronic kidney disease later in life. However, human studies exploring maternal vitamin A's impact on fetal kidney development lack longitudinal data and within-cohort comparisons. Furthermore, the influence of provitamin A carotenoids (α-carotene, β-carotene, β-cryptoxanthin) on kidney size remains unexplored. This dissertation addresses these gaps by analyzing relationships between maternal and cord plasma retinol and provitamin A carotenoid concentrations with fetal and infant kidney sizes. Our prospective cohort …

Identification And Preclinical Assessment Of Novel Therapeutic Modalities In Environmental Exposure-Induced Lung Disease, Aaron D. Schwab

Theses & Dissertations

Environmental lung diseases are preventable respiratory conditions either caused or made worse by inhaled environmental exposures. Contemporarily, environmental lung diseases are most associated with workplace exposures given specific occupational processes aerosolize inflammatory agents that can be inhaled at high concentrations. Although a considerable amount is known regarding immunoglobulin (Ig)E-mediated responses to environmental exposures, little is known about non-IgE mediated respiratory conditions resulting from lipopolysaccharide (LPS)-enriched organic dust exposure(s). Chronic respiratory diseases such as asthma, hypersensitivity pneumonitis, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis have all been identified as environmental lung diseases caused or exacerbated by such environmental dusts. Therapeutic …

Cholestasis And Fluid Flow Are Biomechanic Regulators Of Cholangiocarcinoma Progression, Andrew Oleksijew

Theses & Dissertations

Cholestasis, altered or absent bile flow, is associated with poor survival in patients with cholangiocarcinoma, an aggressive cancer of the biliary epithelium. Changes in bile flow often result in stricture or obstruction. Experimental cholestasis promoted tumor growth and progression. However, studies are needed that directly assess the mechanical interaction between bile flow, or bile shear stress, and cholangiocarcinoma signaling. We hypothesized that cholestasis and absent bile shear stress activated cancer signaling and increased aggressive cellular behaviors such as proliferation and migration. Fluid shear stress approximating bile flow was applied by orbital culture plate method and compared to identical static culture …

Intrinsic And Extrinsic Drivers Of Bioaerosol Decay: Investigating Pathogen Stability Of Bacteriophage Ms2, Sin Nombre Virus, And Sars-Cov-2 In Simulated Environments, Elizabeth A. Klug

Theses & Dissertations

The threat posed by a virus as a bioaerosol depends largely on its stability under various environmental conditions (relative humidity (RH), sunlight, ozone, etc.). This stability is typically studied through aerosol decay—how the virus' viability changes over time when exposed environmental conditions. The Goldberg rotating drum, a widely used tool for studying bioaerosols, has been the basis of such research (Goldberg et al., 1958). However, it has significant limitations, including an inability to measure initial pathogen infectivity loss and the use of small sample volumes. Additionally, it does not answer the question of what intrinsic factors (lipids, proteins, nucleic acids) …

Neurodegenerative Disease Mechanisms: Mitochondrial Impairment, Tau Aggregation, And Neuroinflammation As Central Drivers Of Disease Progression, Luis D. Estrella

Theses & Dissertations

The study of the intricate molecular mechanisms behind the pathology of neurodegenerative diseases has become a primary research area in the past decades. The major branches of these studies involve both disease progression and disease pathogenesis, in which neuroscientists have studied, and continue to study, the role that mitochondrial dysfunction, aberrant protein aggregation (like Tau), and immune cell reactions have on these. However, more recent studies have shined light to the fact that these three pathological features are not independent from one another and that their synchronous contributions may be the ultimate driver of neurodegeneration. This dissertation encompasses four different …

Drivers And Mechanisms Of Golgi Fragmentation As A Modulator Of Disease, Amanda Macke

Theses & Dissertations

The Golgi apparatus plays a pivotal role in post-translational modification, trafficking, and secretion of proteins, ensuring proper cellular function. As a result, its fragmentation has been implicated in multiple pathological conditions, including alcohol-induced liver injury and prostate cancer (PCa).

Apolipoprotein E4, Tauopathy, And Brain Injury: Molecular Insights Into Alzheimer's Disease Pathology, Nashanthea J. Roland

Theses & Dissertations

Alzheimer’s disease (AD) is the world’s leading cause of dementia, characterized by progressive atrophy of the hippocampal and cortical brain regions, synapse damage and loss, and a buildup of senile plaques and neurofibrillary tangles composed of β-amyloid peptides and hyperphosphorylated tau, respectively. While age is the most significant risk factor for developing AD, apolipoprotein E4 (APOE4) is the strongest genetic risk factor for AD. Although it is known that APOE4 influences tau pathology, the molecular mechanisms by which APOE4 drives AD pathogenesis and progression remain unclear. In addition to intrinsic contributions to AD, there are many extrinsic factors that can …

Claiming More To Cope: Does Ostracism Increase Overclaiming?, Katy Q. Chen

Honors Theses

In a pre-registered online study, we investigated the relationship between ostracism and overclaiming. Ostracism is the act of deliberately or unintentionally excluding and ignoring others. Overclaiming refers to the behavior of exaggerating one’s knowledge or familiarity with specific topics, often as a way of attempting to present oneself as more knowledgeable or competent than one actually is. Drawing from the temporal need-threat model, we hypothesized that ostracized individuals, as a compensatory response, would likely overclaim more compared to included individuals. This online study simulated a work experience where participants were asked to answer questions about their work-related experiences and opinions. …

The Impact Of Antimicrobial Peptide Depletion And Fungal Infection On Thermal Preference In Green Frogs, Rana Clamitans, Kim M. Salvador

Honors Theses

Climate change and the disease chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd), are the two main drivers of amphibian decline worldwide, but it is difficult to predict the outcomes of these interacting stressors. Amphibians are ectotherms meaning they are dependent on environmental temperature for the maintenance of physiological processes, and they rely on behavioral thermoregulation to maintain body temperatures within their thermal limits. As the climate becomes more variable, amphibians are also potentially more susceptible to diseases such as Bd, as their immune defenses, such as antimicrobial peptide (AMP) defenses of the skin, take longer to …

Impacts Of Polyploidization On Endocrine Regulation And Vocalization In The Gray Treefrog Complex, Avery Thigpen

Honors Theses

Comparative genomics data suggest that vertebrates are descendants of ancestral polyploids and that historical polyploidization events fueled evolutionary innovations. For example, polyploidization can modify gene expression patterns and/or increase gene mutation rates to alter the phenotype. While considerable emphasis has been placed on the evolutionary impact of ancient polyploidization events, less is known regarding phenotypic modifications in extant polyploids. I examined circulating levels of adrenal glucocorticoids and gonadal steroids in the diploid-tetraploid gray treefrog complex to understand how polyploidization has impacted hormonal regulation. Furthermore, I examined the relationships between levels of these hormones and acoustic signals to examine if and …

The Role Of Presynaptic Proteins In Alcohol Sensitivity And Tolerance, Madhumitha Gundluru

Honors Theses

Mammalian Unc13 (Munc13) and Drosophila Unc13 (Dunc13) are presynaptic active zone proteins essential for synaptic vesicle docking and priming in a neuron. Alcohol binds to the C1 domain of Munc13, which inhibits DAG binding. The reduction in DAG binding by Munc13 decreases the probability of vesicle fusion with the membrane, decreasing neurotransmitter release. Heterozygotes for a Dunc13 loss-of-function allele are behaviorally resistant to alcohol, physiologically resistant to alcohol, molecularly resistant to alcohol, and self-administer significantly more alcohol than control flies. Therefore, genetically reducing Dunc13 mimics a state of alcohol tolerance in the fly. The two main Dunc13 isoforms, Dunc13A and …

Cholesterol Mass Fingerprinting To Probe Cholesterol-Protein Interactions, Warren Lowther

Electronic Theses and Dissertations

Cryomicroscopy, crystallography and NMR have been considered the “gold standard” of structural biophysics for some time. Recent successes in using these techniques has provided us with a plethora of insight into the architecture of different macromolecules like channels, transporters, and other molecular machines. However, information is often limited to a single allosteric state with the macromolecule in a non-native environment. Additionally, these traditional methods tend to be expensive and labor-intensive, requiring samples that are concentrated and highly purified. Chemical crosslinking coupled with mass spectrometry (CX-MS) has emerged as the ideal accessory for the aforementioned structural tools. In order to address …
