Generative And Ai Authored Artworks And Copyright Law, Michael D. Murray

Law Faculty Scholarly Articles

Generative art linked to non-fungible tokens (NFTs) is an extremely popular genre of art in the NFT universe. Many of the most famous NFT projects—CryptoPunks, Bored Ape Yacht Club, World of Women, Azuki, Chromie Squiggles, Clone X, and Moonbirds, just to name a few—involve generative art. But there is a potential copyrightability problem with generative art:

Under current United States copyright law, many examples of generative art might be held to be uncopyrightable.

Why does generative art fail in the copyrightability analysis? As discussed below, it is because the work might lack a human author. And at present, the U.S. …

Development And Biological Evaluation Of Selective Small-Molecule Inhibitors Of The Human Cytochrome P450 1b1, Austin Hachey

Theses and Dissertations--Chemistry

The human cytochrome P450 1B1 (CYP1B1) is an emerging target for small- molecule therapeutics. Several solid tumors overexpress CYP1B1 to the degree that it has been referred to as a universal tumor antigen. Conversely, its expression is low in healthy tissues. CYP1B1 may drive tumorigenesis through promoting the formation of reactive toxins from environmental pollutants or from endogenous hormone substrates. Additionally, the expression of CYP1B1 in tumors is associated with resistance to several common chemotherapies and with poor prognoses in cancer patients. However, inhibiting CYP1B1 with small molecules has been demonstrated in cellular and murine model systems to reverse this …

Paper Gowns, Cold Hands, Or Something Else? Black Women's Barriers To Gynecologic Screening, Nadia Ayesha Sesay

Theses and Dissertations--Communication

Cervical cancer mortality burden is carried disproportionately by African American women. Early indicators of cervical cancer are identified through prevention screening, a procedure typically performed by a gynecologist. Ideally, the patient group with the most severe mortality would likewise be the group with the most robust communication exchange with their physician to prevent cervical cancer incidence. However, a slew of factors contributes to continued mortalities among Black women. This study uses semi-structured interviews (n=10) and the health belief model to examine one barrier to Black women’s prosocial behaviors regarding routine gynecologic care—awkwardness, which here is conceptualized as social anxiety. The …

Identity And Perception Among Aspec Consumers Of Mass Media, Jericho Franke

Theses and Dissertations--Communication

The portrayals of sex and romance, as well as asexuality and aromanticism, in mass media can have a profound impact on the way asexual and aromantic media consumers view relationships and their own identities, and affect the perception and treatment of the aspec community as a whole. This study uses mixed qualitative methods of online discourse analysis and participant interviews to examine the how mass media has shaped the self-perception and life experiences relating to sex and romance among aspec audience members.

A Mor Antagonist With High Potency And Antagonist Efficacy Among Diastereomeric C9-Alkyl-Substituted N-Phenethyl-5-(3-Hydroxy)Phenylmorphans, Dana R. Chambers, Agnieszka Sulima, Dan Luo, Thomas E. Prisinzano, Arthur E. Jacobson, Kenner C. Rice

Pharmaceutical Sciences Faculty Publications

The 5-(3-hydroxy)phenylmorphan structural class of compounds are unlike the classical morphinans, 4,5-epoxymorphinans, and 6,7-benzomorphans, in that they have an equatorially oriented aromatic ring rather than the axial orientation of that ring found in the classical opioids. This modified and simplified opioid-like structure has been shown to retain antinociceptive activity, depending on its stereochemistry and substituents, and some of them have been found to be much more potent than morphine. A simple C9-hydroxy-5-(3-hydroxy)phenylmorphan enantiomer was found to be about 500 times more potent than morphine in vivo. We have previously examined C9-alkenyl and hydroxyalkyl substituents in the N-phenethyl-5-(3-hydroxy)phenylmorphan class of compounds. …

Using 3-Dimensional Mapping To Determine The Possibility Of Structural Control On Development Of The Upper Ordovician Lexington Limestone, Central Kentucky, U.S.A., Sean Davis

Theses and Dissertations--Earth and Environmental Sciences

The upper Lexington Limestone of Late Ordovician age has been interpreted to represent a structurally controlled, complex, facies mosaic. This facies mosaic has historically been interpreted to be a carbonate buildup of shoal complexes with interbedded shale units with intertonguing facies. Due to relatively recent advances in geographic-information-systems (GIS) mapping technologies, it is possible to generate three-dimensional (3-D) compatible maps to offer insight to the complexities of the upper Lexington Limestone and to determine if structural control affected the distribution of members. The resulting two-dimensional (2-D) and 3-D maps show that basement faults likely exerted a significant influence on facies …

Selenium Form-Induced Changes In The Early Luteal Phase Corpus Luteum, The Blood, And The Endometrium During Early Gestation In Beef Cows, Sarah Nancy Carr

Theses and Dissertations--Animal and Food Sciences

Selenium (Se) deficient soils and thus forages are widespread throughout the United States, necessitating supplementation of this trace mineral in the diet of grass-fed cattle to negate detrimental effects of a deficiency on immune function, growth, and fertility. Conventionally, Se is supplemented to cattle in a vitamin-mineral mix as an inorganic form (ISe) although the organic forms (OSe) are available when cattle consumer forage, and OSe has been shown to increase the bioavailability of Se in cattle. Previous research has demonstrated supplementation with 1:1 mixture (MIX) of ISe and OSe compared to ISe alone increases systemic concentrations of progesterone (P4) …

Increasing Efficiency Of Finishing Beef Production: Strategies To Optimize Starch Digestion, Improve Flake Quality, And Reduce Methane Emissions, Ronald J. Trotta

Theses and Dissertations--Animal and Food Sciences

To continue to meet the demands of increasing food production and environmental sustainability, new strategies are needed to enhance the efficiency of finishing cattle production. A review of the literature identified several nutritional and physiological constraints that limit the ability for cattle to digest starch and absorb glucose from the small intestine. Comparative sequencing analyses revealed a missing region of the sucrase-isomaltase protein which could affect the capacity for starch digestion in cattle. Post-flaking sampling and handling recommendations were generated based on a series of experiments to improve estimates of starch availability and flaking consistency for commercial feedlots and laboratories. …

Plant Cell Wall Composition And In Vitro Fermentation Characteristics Of Cool-Season Forage Grasses From Two Growing Seasons In Central Kentucky, Sophia Danielle Newhuis

Theses and Dissertations--Animal and Food Sciences

Grass cell walls are rich in cellulose, hemicellulosic arabinoxylan (AX) polysaccharides, and lignin. AX structural differences such as degree and pattern of branching and the ester-linked phenolic acid content could affect plants’ digestibility when used as forage for livestock. However, there is little information about how these structural elements change over the growing season in the vegetative tissue of cool-season perennial grasses. Enhanced information about the cell wall composition and carbohydrate structure of forage material will provide a foundation for expanding our knowledge of how forage cell wall carbohydrate structures are utilized by ruminants. The objectives of this study were …

Evaluation Of Boron Supplementation In Swine And Poultry, Tyler B. Chevalier

Theses and Dissertations--Animal and Food Sciences

The objectives of this dissertation were to evaluate dietary boron (B) supplementation as sodium borate in various swine models and broiler chicks through a series of experiments. The initial experiment evaluated supplemental B (0, 25, 50, and 100 ppm B) on serum insulin, glucose, and clinical chemistry panel of growing pigs. Serum insulin/glucose ratio tended to decrease linearly with increasing supplemental B in a fasting state (P = 0.08). These findings were more noticeable (linear effect, P = 0.02) in a postprandial state (~ 50 minutes following a meal). A series of follow-up studies further evaluating B supplementation (0, 5, …

Evaluation Of Increasing Levels Of Mycotoxin-Containing Corn Fines On Diet Choice And Growth Performance Of Nursery Pigs, Duncan B. Paczosa

Theses and Dissertations--Animal and Food Sciences

Pigs fed mycotoxin contaminated diets at high concentrations will result in a detriment to health and performance. An initial study and a follow-up study were conducted to evaluate the effects of feeding increasing levels of mycotoxin-containing corn fines on growth performance, diet preference of pigs, and two possible mitigants.

The initial study was a 3 x 2 factorial containing three levels of fines (0, 10, and 20%, Diets 1-3, respectively) and either 0 ppm (Diets 1-3) or 40 ppm boron (Diets 4-6; Diets 4-6 were Diets 1-3, respectively, plus boron) as sodium tetraborate decahydrate as a possible mitigant. In this …

Profiling The Cell Wall Polysaccharides Of Hemp (Cannabis Sativa L.) Inflorescence And Hempseed And Exploring Their Application As Ruminant Feed Ingredients, Miranda Agbana

Theses and Dissertations--Animal and Food Sciences

Hemp (Cannabis sativa L.) is used in the United States as a source of CBD oil, fiber, and grain. While hempseeds are consumed whole or as dehulled hemp hearts, hempseed oil is also a desirable seed oil in human nutrition. The process of collecting hempseed oil leaves behind hempseed cakes that are abundant in protein and fiber. Feeding of hempseed cakes to animals, including ruminants, has only initially been explored. Extraction of CBD from hemp inflorescences generates organic waste that may find a second purpose as a fiber feed for cattle. Little is known about the exact fiber composition …

Ultrasound-Based Structural And Functional Modifications Of Oat Protein: Complementary Effects Of High Pressure, Cysteine, And Flavonoids, Runnan Li

Theses and Dissertations--Animal and Food Sciences

Oat (Avena sativa L.), a specialty cereal grain belonging to the Poaceae family, is relatively abundant in nutritious protein (12–20%) and dietary fiber (β-glucan). The balanced hydrophilic/hydrophobic amino acid profile in oat protein relative to other plant sources provides numerous possibilities for formulating oat protein isolate (OPI) into a wide range of food products. Yet, there has been limited research on OPI and the application of this valuable protein source is hampered by its low solubility at neutral and mildly acidic conditions. This dissertation research aimed to elucidate the efficacy of high-intensity ultrasound (HIU) for structural modification of OPI …

Precision Livestock Farming And Personality As Tools To Understand Dairy Calf Individual Variation In Performance, Behavior, And Response To Stress, Megan Marie Woodrum Setser

Theses and Dissertations--Animal and Food Sciences

Individual differences impact animal responses to their environments and can be observed with animal personality (stable behavioral differences with populations) and food neophobia (avoidance of unfamiliar feeds). These individual differences can influence cattle performance and welfare. Precision technologies, such as automatic feeding systems (AFS) and accelerometers continuously measure feeding behaviors and activity and may allow us to relate individual differences to behaviors in the home environment. Therefore, the first objective was to determine if food neophobia was associated with feeding behaviors measured by AFS. Food neophobia was associated with rewarded visits to the AFS, but to no other feeding behaviors. …

Campylobacter Vaccination Reduces Diarrheal Disease And Infant Growth Stunting Among Rhesus Macaques, Sara M. Hendrickson, Archana Thomas, Hans-Peter Raué, Kamm Prongay, Andrew J. Haertel, Nicholas S. Rhoades, Jacob F. Slifka, Lina Gao, Benjamin K. Quintel, Ian J. Amanna, Ilhem Messaoudi, Mark K. Slifka

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Campylobacter-associated enteric disease is estimated to be responsible for more than 160 million cases of gastroenteritis each year and is linked to growth stunting of infants living under conditions of poor sanitation and hygiene. Here, we examine naturally occurring Campylobacter-associated diarrhea among rhesus macaques as a model to determine if vaccination could reduce severe diarrheal disease and infant growth stunting. Compared to unvaccinated controls, there are no Campylobacter diarrhea-associated deaths observed among vaccinated infant macaques and all-cause diarrhea-associated infant mortality is decreased by 76% (P = 0.03). By 9 months of age, there is a 1.3 cm increase in dorsal …

Chronic Alcohol Consumption Dysregulates Innate Immune Response To Sars-Cov-2 In The Lung, Sloan A. Lewis, Isaac R. Cinco, Brianna M. Doratt, Madison B. Blanton, Cherise Hoagland, Natali Newman, Michael Davies, Kathleen A. Grant, Ilhem Messaoudi

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Background Alcohol consumption is widespread with over half of the individuals over 18 years of age in the U.S. reporting alcohol use in the last 30 days. Moreover, 9 million Americans engaged in binge or chronic heavy drinking (CHD) in 2019. CHD negatively impacts pathogen clearance and tissue repair, including in the respiratory tract, thereby increasing susceptibility to infection. Although, it has been hypothesized that chronic alcohol consumption negatively impacts COVID-19 outcomes; the interplay between chronic alcohol use and SARS-CoV-2 infection outcomes has yet to be elucidated.

Methods In this study we employed luminex, scRNA sequencing, and flow cytometry to …

Integrated Single Cell Analysis Shows Chronic Alcohol Drinking Disrupts Monocyte Differentiation In The Bone Marrow, Sloan A. Lewis, Brianna M. Doratt, Qi Qiao, Madison B. Blanton, Kathleen A. Grant, Ilhem Messaoudi

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Chronic heavy alcohol drinking (CHD) rewires monocytes and macrophages toward heightened inflammatory states with compromised antimicrobial defenses that persist after 1-month abstinence. To determine whether these changes are mediated through alterations in the bone marrow niche, we profiled monocytes and hematopoietic stem cell progenitors (HSCPs) from CHD rhesus macaques using a combination of functional assays and single cell genomics. CHD resulted in transcriptional profiles consistent with increased activation and inflammation within bone marrow resident monocytes and macrophages. Furthermore, CHD resulted in transcriptional signatures associated with increased oxidative and cellular stress in HSCP. Differentiation of HSCP in vitro revealed skewing toward …

Understanding And Targeting The Tph1-Serotonin-Htr3a Axis In Small Cell Lung Cancer, Yanning Hao

Theses and Dissertations--Toxicology and Cancer Biology

Small cell lung cancer (SCLC), which accounts for 10-15% of all lung cancer, is the most malignant type that tends to grow fast and spread in its early stages. The 5-year survival rate remains low at 6% overall. Thus, new therapeutic methods and pharmacological targets for SCLC patients are urgently needed. We present novel data indicating that the synthesis of serotonin is upregulated in SCLC compared to normal bronchial epithelial cells and non-small cell lung cancer. Serotonin signaling plays a critical role in various physiological and pathological processes. However, its contribution to SCLC development has not been well understood. The …

Targeting Ezh2 To Improve Outcomes Of Lung Squamous Cell Carcinoma, Tanner Ducote

Theses and Dissertations--Toxicology and Cancer Biology

Only 20% of patients diagnosed with lung squamous cell carcinoma (LSCC) respond to immunotherapy. Anti-PD1 immunotherapy is most commonly prescribed to these patients; however, most will become refractory. It is important to understand the mechanisms underlying this problem to increase durability and survival. Building upon the work of other groups, our lab has demonstrated that the inhibition of the histone methyltransferase, EZH2, is crucial to maintaining an immunologically responsive microenvironment. Based on our data, we hypothesize that combining EZH2 inhibitors with anti-PD1 therapy will increase response and durability. To study non-small cell lung cancers (NSLC) our lab uses a variety …

Foraging Behavior In The Eastern Subterranean Termite, Reticulitermes Flavipes (Kollar) (Isoptera: Rhinotermitidae), Anugerah Fajar

Theses and Dissertations--Entomology

Foraging is essential for survival, but it can be unpredictably dangerous due to organismal interactions like competition and predation to various environmental factors. Animals have come up with strategies to safeguard foraging. Social insects, with their elaborate division of labor, have developed sophisticated systems of foraging task allocation that allow them to capitalize resources beyond their competitors. In this thesis, I delve into the subjects of foraging behavior, allocation strategies, and the genetic basis of foraging in the eastern subterranean termite, Reticulitermes flavipes, the most widely distributed termite species in North America and one of the most economically important …

Anti-Inflammatory And Analgesic Effects Of Highly Selective Microsomal Prostaglandin E2 Synthase-1 (Mpges-1) Inhibitors, Madeline Stewart

Theses and Dissertations--Pharmacy

Lipid messenger prostaglandin E2 (PGE₂) is a prostanoid that plays a key role in the generation of the inflammatory response. Currently available non-steroid anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase (COX)-1 and/or COX-2, all with significant cardiovascular, cerebrovascular, and gastrointestinal risks that have limited their utilization. Microsomal PGE₂ synthase 1 (mPGES-1), an inducible enzyme responsible for overproduction of PGE₂, may be a more promising target for a new type of anti-inflammatory drug without the adverse effects associated with the COX-1/2 inhibition. There have been extensive efforts to design and discover inhibitors targeting mPGES-1. Unfortunately, within the previously …

Developing Ecologically Valid Clinical Tools For Persons With Tbi: Understanding The Role And Impact Of Distractions, Deanna Pinnow

Theses and Dissertations--Rehabilitation Sciences

There is a critical need for the development of ecologically valid clinical tools to assess real-life cognitive functioning in persons impacted by traumatic brain injury (TBI). Chronic cognitive impairments that are exacerbated by distractions are one of the core factors contributing to poor home and community re-integration post injury. Simulation-based digital platforms (i.e., virtual reality, augmented reality, and mixed reality) have become potential solutions for eliciting real-world cognitive performance in clinical settings. Yet, there is a paucity of research investigating the role and impact of distractions on cognition. As a result, there is no clear framework of measuring distractions to …

Consumers’ Preferences And Willingness To Pay For Value-Added Dairy Products In Kentucky - Considering Price, Provenance, And Environmental Product Attributes, Favour E. Esene

Theses and Dissertations--Agricultural Economics

Many medium and smaller dairies are shifting to various kinds of value-added products that may expand in demand nationally aside from fluid milk. This study uses a latent class logit model to investigate the heterogeneity of consumer preferences and willingness to pay for dairy value-added products across four latent classes considering different local and environmental sustainability labels. The dairy products examined for this research are butter, cheese, yogurt, and ice cream. This research revealed that younger consumers, especially those that reside in rural areas, always pay attention to product attributes when they shop for dairy products, mostly the local state …

Adolescent Intermittent Ethanol Drives Modest Neuroinflammation But Does Not Escalate Drinking In Male Rats, Jessica I. Wooden, Lauren E. Peacoe, Chinchusha Anasooya Shaji, Jennifer K. Melbourne, Cassie M. Chandler, Michael T. Bardo, Kimberly Nixon

Psychology Faculty Publications

During adolescence, the brain is highly susceptible to alcohol-induced damage and subsequent neuroimmune responses, effects which may enhance development of an alcohol use disorder (AUD). Neuroimmune reactions are implicated in adolescent alcohol exposure escalating adulthood drinking. Therefore, we investigated whether intermittent alcohol exposure in male, adolescent rats (AIE) escalated adult drinking via two-bottle choice (2BC). We also examined the influence of housing environment across three groups: standard (group-housed with enrichment during 2BC), impoverished (group-housed without enrichment during 2BC), or isolation (single-housed without bedding or enrichment throughout). In the standard group immediately after AIE/saline and after 2BC, we also examined the …

Prenatal Morphine Exposure Increases Cardiovascular Disease Risk And Programs Neurogenic Hypertension In The Adult Offspring, Nermin Hassan Mohamed Selim Ahmed, Alana Kassis, Jena Malone, Jodie Yang, Esraa Zamzami, An-Hsuan Lin, Scott M. Gordon, Ming C. Gong, Michael T. Bardo, Carolina Dalmasso, Analia S. Loria

Psychology Faculty Publications

BACKGROUND: The opioid overdose and opioid use disorder epidemics are concomitant with increased metabolic and CVD risk. Although opioid use disorder causes adverse pregnancy outcomes, the offspring’s cardiovascular health is understudied. We hypothesized that offspring exposed to in utero morphine exposure (IUME) would show increased CVD risk factors and endogenous opioid system dysregulation.

METHODS: Sprague Dawley dams were treated with saline (vehicle, n=10) or escalating doses of morphine (5–20 mg/kg per day, SC, n=10) during gestation. Cardiovascular and metabolic parameters were assessed in adult offspring.

RESULTS: Litter size and pups’ birth weight were not different in response to IUME. Female …

Effect Of The Glucocorticoid Receptor Antagonist Pt150 On Acquisition And Escalation Of Fentanyl Self-Administration Following Early-Life Stress, Michael T. Bardo, Cassie M. Chandler, Emily D. Denehy, Benjamin A. Carper, Mark A. Prendergast, Tracy L. Nolen

Psychology Faculty Publications

There is comorbidity between posttraumatic stress disorder (PTSD) and opioid use disorder (OUD), perhaps because PTSD-like stressful experiences early in life alter the hypothalamic–pituitary-adrenal stress axis to increase the risk for OUD. The present study determined if the glucocorticoid receptor antagonist PT150 reduces the escalation of fentanyl intake in rats exposed to a “two-hit” model of early-life stress (isolation rearing and acute stress). Male and female rats were raised during adolescence in either isolated or social housing and then were given either a single acute stress (restraint and cold-water swim) or control treatment in young adulthood. Rats were then treated …

Rapid Scoping Review Of The Epidemiological Evidence For Mercury Exposure And Prevalence Of Alzheimer’S Disease, Rebecca Mattingly

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

This rapid scoping review examines the current body of epidemiologic research evaluating the potential linkage between environmental exposure to mercury and Alzheimer's disease (AD). Alzheimer’s disease accounts for 60-80% of all neurodegenerative disease in the United States and was the seventh leading cause of death in Kentucky in 2020. The exact etiology of AD needs further investigation; however, environmental factors such as pesticides, arsenic, cadmium, lead, and mercury have been correlated with development of AD lesions, cognitive decline, and AD. Mercury is a toxic metal that can be found in air, water, and soil, both from natural and human-made sources. …
