Disruption Of The Placenta–Brain Axis In Transgenic Mice Lacking Serotonin Transporter (Sert) In Trophoblast Cells, David T. Ellenberger, Zhen Lyu, Rosalind T. B. Herrington, Jessica A. Kinkade, Gustavo W. Leone, Ji Ying Sze, Nathan J. Bivens, R. Frank Baker, R. Michael Roberts, Trupti Joshi, Cheryl S. Rosenfeld

Biomedical Sciences

Serotonin reuptake inhibitors (SSRIs) are commonly prescribed to pregnant women experiencing depression. Such drugs, however, might adversely affect placenta and fetal brain development. Parietal trophoblast giant cells (pTGCs) in the mouse placenta are postulated to internalize maternal serotonin (5-HT) via transport through SERT, encoded by Slc6a4, and to provide the initial source of 5-HT to the emerging brain via the placental–brain axis. Genetic deletion of Slc6a4 in pTGCs has been hypothesized to impact placental and fetal brain development. A transgenic mouse line with high-affinity SERT, encoded by Slc6a4, was selectively deleted by pairing mice with Cre recombinase linked …

Effects Of Injectable Trace Mineral Timing On Calf Performance And Health Indicators, Marie E. Goulais

Graduate Theses and Dissertations

One hundred and fourteen calves (average BW= 224kg ± 89kg) were utilized to evaluate the effects of injectable trace mineral (ITM) administration on calf performance and health when administered pre-weaning and at weaning. Calves were blocked by sex, stratified by age, and randomly assigned to one of the following treatment groups: 1) no ITM injection (CON), 2) ITM administered 28 d before weaning (PW), or 3) ITM administration at weaning (WEAN). Calves were vaccinated against respiratory pathogens on D-28 and D0. At weaning, cattle were transported to a local auction market, held overnight and returned the following morning. Body weight …

Effect Of Peracetic Acid Dip Frequency On The Quality And Functional Properties Of Non-Marinated And Marinated Broiler Tenderloins, Joaquin Jose Esquivel Vergara

Graduate Theses and Dissertations

The poultry industry continues to balance the need for effective antimicrobial interventions with the preservation of meat quality. Among the most widely used antimicrobial agents, peracetic acid (PAA) has proven effective for reducing foodborne pathogens in poultry products. However, excessive or repeated exposure to PAA can influence meat functionality by altering protein structure, color, and water-holding capacity. Therefore, the broad objective of this study was to evaluate the effect of PAA dip frequency and post-treatment marination timing on the physicochemical and functional quality of broiler tenderloins (Pectoralis minor), in order to provide processing insights that optimize both microbial safety and …

Hormonal Control Of Seawater Acclimation In The Intestine Of The Atlantic Killifish (Fundulus Heteroclitus), Karma Je Hine

Graduate Theses and Dissertations

The Atlantic killifish (Fundulus Heteroclitus) is a teleost found in brackish water estuaries, which are subject to large fluctuations in salinity, that handles osmotic stress by triggering compensatory actions across their osmoregulatory organs. As the external salinity increases, the killifish intestine exhibits a high degree of phenotypic plasticity, as the protein composition of the gut epithelium can be modified to absorb desalinated water (H2O) from ingested seawater (SW). Three osmoregulatory hormones, prolactin (P), growth hormone (GH), and cortisol (F), have been observed to be crucial for these transitions to occur in many species of teleosts, including killifish. This research sought …

Finding Utopia: An Examination Of Pedagogical Approaches To Teaching Utopianism In U.S. College Classrooms, Brittany Page Brake

Dissertations

This dissertation investigates how, and if, utopianism is being taught in college classrooms across the United States. Long considered impractical, overly idealistic, and/or politically dangerous, utopianism has been largely marginalized in political science and American culture. However, this project finds that there are instructors teaching utopianism and they are using the concept to challenge students to think differently about governance, justice, and institutional design. Drawing from political theory literature, course syllabi submitted by faculty from different U.S. universities, interviews with instructors, and personal case studies of my own courses at Central State University and Manchester University, I explore how utopian …

Triple-Parametric Autoencoder For 2d Reparameterization Via Bézier, B-Spline, And Nurbs Representations, Shaoliang Yang, Jun Wang

Mechanical Engineering

This paper proposes a sample-wise triple-parametric deep learning framework (TPDLF) for 2D curve parameterization. The proposed framework integrates Bézier, B-spline, and Non-Uniform Rational B-spline (NURBS) curve formulations within a unified neural network architecture, enabling the reconstruction of smooth and closed 2D curves such as real-world airfoil and synthetic Superformula shapes (with -fold symmetry). An encoder compresses the input curve shape into a latent space, while three distinct decoders untangle the latent space by inferring corresponding governing parameters for each parameterization (i.e., Bézier/B-spline/NURBS). The corresponding reconstruction modules are then deployed to ensure smooth curve generation using the governing parameters …

Differences In Loading Rate In Shod And Unshod Treadmill Walking, David Austin Kropushek

Master's Theses

The purpose of this study was to compare the loading rates of shod and unshod conditions in treadmill walking. It was hypothesized that walking barefoot would demonstrate higher loading rates than walking with shoes. It was also hypothesized that walking barefoot on a treadmill would result in greater stride-to-stride variability than walking with shoes. Sixteen healthy adult females volunteered and provided their consent to participate in this study. Participants were given time to accommodate to the instrumented treadmill both while wearing shoes and without. Two 10-minute trials were collected with a rest period between. Data were analyzed using Vicon Nexus …

Coming To The American Vincentian Mission In 1818: The Second Journey, John E. Rybolt C.M.

Vincentian Studies

Three letters from Francesco Cellini, a Vincentian novice, and his confrere, Filippo Borgna, a Vincentian student with vows, are given or summarized here. In 1818, Cellini and Borgna made an eighty-eight-day voyage from Livorno, Italy, to the United States. Cellini wrote an account to a friend in Rome, and Borgna largely copied this in his letter, perhaps to ensure that one of their texts would survive the trip back to Italy. These are the only known detailed records of the Vincentians’ second journey to the US and reinforce records kept by Felix De Andreis and Joseph Rosati, who came two …

Emergency Lending By The Federal Reserve, Kathryn Judge, Richard Clarida

The Federal Reserve established an array of innovative emergency lending facilities during the Great Financial Crisis and expanded the scope of its emergency lending yet further in response to the Covid-19 pandemic. This Article provides a retrospective of how the Federal Reserve used its emergency lending authority across these two episodes, identifying patterns and revealing some differences. It sheds light on the conditions that enabled the Federal Reserve to establish the facilities that it did, including the roles played by Congress and Treasury in providing the equity funding that made certain facilities possible. It shows how in each episode, the …

Mouthpieces Of The God: On Translating Bacchae, Finnegan N. Beaty

Honors Theses

Euripides’ Bacchae is one of the most well-known and most frequently performed Greek tragedies. However, it is too often distanced from its origins in the Dionysia, a religious festival celebrated in honor of the god Dionysus, at which it was performed as part of tragic ritual. This paper analyzes the specific translation choices of three authors, Anne Carson, Gilbert Murray, and Emily Wilson, and how they affect the meanings of their different translations as a whole. These choices are broken down according to three domains, inspired by Aristotle’s definition of tragedy in Poetics. The religious, cathartic effect of each play …

“If He Be Mr.Hyde…I Shall Be Mr.Seek”: Crime, Surveillance, And Narrative Structure In The Strange Case Of Dr. Jekyll And Mr. Hyde, Haley N. Durrett

Honors Theses

This research seeks to situate Robert Louis Stevenson's novella, The Strange Case of Dr. Jekyll and Mr. Hyde into the historical context of the time period using 19th century criminal-typing, policing structures, and the genre of detective fiction. Focusing on the representation of the criminal, Edward Hyde, the layout of the detective novel, and narrative structure, the novel creates an implicit desire for the police, that is not fulfilled throughout the novel's unraveling.

Examing Fear Conditioning/Extinction And The Role Of The Amygdala In Human Neuroimaging., Olivia Cook

Electronic Theses and Dissertations

Fear plays a crucial role in survival but can lead to psychological disorders when dysregulated. Fears can be innate due to evolutionary relevance or learned through associative processes, where predictive accuracy of threat is pivotal. Disruptions in fear neurocircuitry contribute to anxiety disorders, characterized by heightened activation and impaired learning. Fear conditioning and extinction paradigms based on classical Pavlovian conditioning have been used to study mechanisms underlying fear learning. Using this experimental model, fear networks in rodents have been described in detail with clear distinction between conditioning and extinction neural functioning. Yet, there is no consensus on the neurobiological processes …

Characterizing The Ethanol Sensitivity Of The Planar Cell Polarity Pathway In Endoderm Morphogenesis And Jaw Development., Raéden Omneil C. C. Rolle Gray

Electronic Theses and Dissertations

Fetal Alcohol Spectrum Disorders (FASD) describes a large range of developmental defects due to prenatal alcohol exposure. It is characterized by neural and facial defects, including jaw hypoplasia. Many factors contribute to the susceptibility of ethanol-induced facial defects, including genetics, yet the genes involved, and the cell events they regulate, are poorly understood. Zebrafish have a large number of tools for genetic manipulation available, share 70% of genes with humans, are fertilized externally and are translucent during embryogenesis, making them great models to study FASD. Previous studies show that two members of the Planar Cell Polarity (PCP) pathway, zebrafish vangl2 …

The Ecology Of Arthropod Rain In A Tropical Forest., Andrew Robert Seiler

Electronic Theses and Dissertations

Tropical forests are structured by complex vertical linkages and nutrient exchanges between canopy and understory habitats. These linkages include the downward flux of organisms, the movement of canopy fauna, and the recycling of nutrients through litter and organic matter deposition. This dissertation investigates arthropod rain and its role in connecting the canopy and forest floor processes in a lowland tropical forest in Panama. Chapter 2 quantifies “arthropod rain”, the fall of canopy arthropods into the understory. Using pan and pole traps, I measured the composition, abundance, and biomass of arthropods falling from the canopy and assessed environmental drivers of the …

Safety Evaluation Of Epicertin, An Oral Biotherapeutic Candidate For Treating Ulcerative Colitis: A 28-Day Repeated Dose Toxicity Study., Jimmy Fernando Cifuentes Jimenez

Electronic Theses and Dissertations

Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic, relapsing inflammation of the colon and rectum with limited treatment options. Among them, immunosuppressive agents have a high rate of adverse side effects and do not cure the disease. EPICERTIN (EPT), a recombinant variant of the cholera toxin B subunit (CTB) with a C-terminal hexapeptide extension consisting of a KDEL endoplasmic reticulum (ER) retention motif, is a promising oral biotherapeutic candidate for the treatment of UC. EPT has demonstrated mucosal healing activity in mouse models of colitis and human colonic explants. EPT's mechanism of action involves binding to GM1 …

Visual Simultaneous Localization And Mapping For Multi-Robot Collaboration, Aidan O’Hare

Electrical and Computer Engineering Master's Theses

As society continues to progress with robotics and automation, the significance of multi-robot systems continues to increase. Single robot systems are limited in their capacity to carry out certain types of tasks, similar to how one person is limited. When it comes to carrying large, cumbersome objects that would require multiple entities to move in a coordinated manner, it is very apparent that implementing a multi-robot system is necessary. Multi-robot systems have become a sector of robotics of increasing interest due to the multitude of use cases they are able to fulfill. However, scalability is a large part of the …

Teaching Copyright Beyond Campus: Academic Librarians At Pop Culture Conventions, Craig Finlay, Isabel Soto-Luna Ed.

Criss Library Faculty Publications

Academic librarianship has long emphasized campus-based instruction, but transformative learning opportunities often emerge beyond the classroom. This article explores how two librarians extended copyright education into the unconventional setting of multigenre pop culture conventions. Originally developed for faculty, their workshops were redesigned to meet the needs of artists, cosplayers, small business owners, and independent creators seeking practical, legally grounded information about copyright, fair use, and intellectual property. Drawing from real-world interactions, iterative feedback, and instructional theory—including a revised “Informative Avocado” model—the authors describe how their outreach not only empowered new learner communities, but also revitalized their own teaching practices. The …

The Effects Of Graded Amounts Of Nicotinic Acid On Cow Health, Colostrum Yield And Quality Of Prepartum Multiparous Jersey Cows And Growth In Their Subsequent Calves, Lydia Joy Valentine

Master's Theses and Capstones

This study evaluated the impact of graded amounts of nicotinic acid (NA) with a negative DCAD diet on cow health, colostrum composition and calf growth performance of Jersey cattle. We hypothesized that NA supplementation would increase IgG concentration of colostrum, increase calf intestinal absorption and growth and improve cow metabolic health. Thirty multiparous Jersey cows were blocked by calving date and assigned to either 0, 8 or 16 g/d of NA supplementation on top of the -40 mEq/kg DCAD dry cow diet. Blood samples were collected weekly for ketone analysis. Urine was collected three times weekly for pH, creatinine and …

Sik2 Inhibitor Grn-300 Enhances Sensitivity To Paclitaxel Treatment In Triple-Negative Breast Cancer, Marc A. Pina

Dissertations and Theses (Open Access)

Breast cancer is one of the most frequently diagnosed cancers worldwide, with approximately 15% classified as Triple-Negative Breast Cancer (TNBC). TNBC lacks expression of estrogen (ER) and progesterone (PR), and does not overexpress HER-2, leaving patients without effective targeted therapies. As a result, treatment primarily relies on chemotherapy, most commonly paclitaxel, a taxane that stabilize microtubules, disrupts chromosome separation and induces apoptosis. However, TNBCs are an aggressive cancer subtype, and patients often will develop resistance after a few rounds of chemotherapy. This study addresses a critical unmet need for more effective TNBC therapies by targeting Salt-Inducible Kinase 2 (SIK2), which …

Structure And Function Studies On Trna Splicing Endonuclease, Justin G. Underwood

Dissertations and Theses (Open Access)

A subset of eukaryotic pre-tRNAs have introns that must be spliced out to become mature molecules capable of functioning in translation. This essential processing step is performed by tRNA splicing endonuclease (TSEN), a highly conserved heterotetramer with two catalytic and two structural subunits. In addition to this conserved function, archaeal TSEN also processes pre-rRNA and yeast TSEN cleaves some mRNAs that encode mitochondrial proteins to initiate mRNA degradation. Interestingly, single amino acid mutations in TSEN cause the human Mendelian disease pontocerebellar hypoplasia (PCH) by an unknown mechanism. Recently, several groups have determined the structure of human TSEN, revealing similarities and …

Host-Intrinsic Factors Determine Anti-Tumor Efficacy Of Exercise In Pancreatic Ductal Adenocarcinoma, Sumedha Pareek

Dissertations and Theses (Open Access)

Pancreatic Ductal Adenocarcinoma (PDAC) is the third leading cause of cancer-related deaths with a low 5-year relative survival rate of approximately 13.3% for all stages combined. We have previously shown that exercise can improve quality of life and enhance functional capacity among patients with PDAC. Exercise induces a variety of changes in the tumor microenvironment with beneficial effects in several tumor types. However, our understanding of the clinical effects of exercise and the mechanisms that mediate anti-tumor effects are limited in pancreatic cancer.

In this project, using C57BL/6 mice from Taconic Biosciences (Tac) and Jackson Laboratories (Jax), we established a …

The (Re)New(Ed) Corporation: Foundation For A Stakeholder Regulatory Agenda, Gregory E. Louis

UC Law Business Journal

Amidst an emerging bipartisan consensus on greater corporate social accountability, America First has joined longstanding solicitude about the racial wealth gap. This Article offers yet another take on corporate purpose. As a project of recovering legal memory like Adrian Vermeule’s common good constitutionalism, it examines scholarship on the history of corporate purpose toward answering whether stakeholder capitalism should inform corporate regulation and, if so, how. It concludes from this history that the Anglo-American legal tradition clearly justifies regulators to hold business corporations accountable to the common good. But it also finds in this history a requirement that stakeholder capitalism be …

Cultural Roots Of Eating: A Comparative Analysis Of Organic Discourse And Marketing Practices In China And The United States, Zubing (Jane) Guo

Honors Theses

This thesis examines how cultural frameworks influence the development of the organic food market and shape individual attitudes towards the label “organic” in the U.S. and China. While the popularity of organic food has increased in recent years, cognitive and behavioral reactions toward the label “organic” have differed across societies. In the U.S., healthy eating discourse aligns closely with the individualistic culture and atomistic cognitive style, highlighting the importance of salient elements such as specific nutrients or chemical use. In contrast, Chinese healthy eating discourse is based on balance and harmony, which is directly related to traditional Chinese culture of …
