Objective: Glucocorticoids are one of the most commonly prescribed classes of anti-inflammatory drugs; however, chronic treatment promotes iatrogenic (drug-induced) diabetes. As part of their physiological role, glucocorticoids stimulate lipolysis to spare glucose. We hypothesized that persistent stimulation of lipolysis during glucocorticoid therapy plays a causative role in the development of iatrogenic diabetes. Methods: Male C57BL/6J mice were given 100 μg/mL corticosterone (Cort) in the drinking water for two weeks and were fed either normal chow (TekLad 8640) or the same diet supplemented with an adipose triglyceride lipase inhibitor (Atglistatin - 2 g/kg diet) to inhibit the first step of lipolysis. …

Exercise is a first-line treatment for type 2 diabetes and preserves b-cell function by hitherto unknown mechanisms. We postulated that proteins fromcontracting skeletalmuscle may act as cellular signals to regulate pancreatic b-cell function. We used electric pulse stimulation (EPS) to induce contraction in C2C12myotubes and found that treatment of b-cells with EPS-conditioned medium enhanced glucose-stimulated insulin secretion (GSIS). Transcriptomics and subsequent targeted validation revealed growth differentiation factor 15 (GDF15) as a central component of the skeletal muscle secretome. Exposure to recombinant GDF15 enhanced GSIS in cells, islets, andmice. GDF15 enhanced GSIS by upregulating the insulin secretion pathway in b-cells,whichwas abrogated …

Quality Of Farmed Shrimp (Penaeus Monodon, Fabricius, 1798 And Macrobrachium Rosenbergii, Deman, 1879) As Affected By Melanosis Inhibiting Compounds, M. Khan, J. A. Lively

Faculty Publications

A problem associated with shrimp is blackspot or melanosis and to prevent blackspot, sulfites have been used for years but come with additional health risks. Newer 4-hexylresorcinol formulations exist that allow sulfite-free shrimp, but effects on the quality of Penaeus monodon Fabricius, 1798, and Macrobrachium rosenbergii, de Man, 1879, beyond melanosis prevention are unknown. Adverse effects on the quality of the shrimp from melanosis prevention treatments would negatively offset the benefits of a sulfite-free product. In order to determine if prevention compounds (sulfite powder or 4-hexylresorcinol based compounds, Everfresh® and Xyrex® Prawnfresh™) affect quality, proximate composition and total plate count …

When Can Local Bird Detection Radars Best Complement Broad-Scale Early-Warning Forecasts Of Risk Potential For Bird–Aircraft Strikes As Part Of An Integrated Approach To Strike Mitigation?, Melanie R. Colón, Ashley M. Long

Faculty Publications

Worldwide, wildlife–aircraft strikes cost more than US$1.2 billion in aircraft damage and downtime and jeopardize the safety of aircrews, passengers, and animals. Radar has long been used to monitor flying animal movements and can be a useful tool for strike mitigation. In the USA, the Avian Hazard Advisory System (AHAS) is an early-warning system that integrates data from next-generation weather radar (NEXRAD) weather surveillance radars (WSRs) with historic bird occurrence data to quantify avian activity and forecast the relative bird risk within a ~9.3-km radius of military and civilian airfields. Bird detection radars (BDRs) with both horizontal-surveillance and vertical-scanning components …

A High-Quality De Novo Genome Assembly For Clapper Rail (Rallus Crepitans), Elisa C. Elizondo, Brant C. Faircloth, Robb T. Brumfield, Subir B. Shakya, Vincenzo A. Ellis, Carl J. Schmidt, Adrienne I. Kovach, W. Gregory Shriver

Faculty Publications

The clapper rail (Rallus crepitans), of the family Rallidae, is a secretive marsh bird species that is adapted for high salinity habitats. They are very similar in appearance to the closely related king rail (R. elegans), but while king rails are limited primarily to freshwater marshes, clapper rails are highly adapted to tolerate salt marshes. Both species can be found in brackish marshes where they freely hybridize, but the distribution of their respective habitats precludes the formation of a continuous hybrid zone and secondary contact can occur repeatedly. This system, thus, provides unique opportunities to investigate the underlying mechanisms driving …

Evolution Of Women’S Consciousness: Toward Integral Consciousness, Katherine T. Ziemke

Journal of Conscious Evolution

This article presents research materials which demonstrate historical consciousness for women of ancient European descent, the cultural heritage of the author. Awareness is examined from various historical angles in a transdisciplinary approach to the work. I explore the possibility that women’s historical and continued oppression may be a sign of the disintegration of the mental and a re-emergence of the integral structure of consciousness. A broad examination of women’s historical roles and corresponding thought shows how ancient consciousness may be used to accelerate a path toward integral consciousness today. Finally, this essay proposes that women’s historical consciousness and primordial memories …

Season Of The Chanterelles And Other Stories, Kirsten Ferguson

Legacy Theses & Dissertations (2009 - 2024)

This collection of short literary fiction springs loosely from a contemplation of the enduring influence of Washington Irving’s Gothic in the Hudson Valley. The first story, “Life Is Good,” centers on a fictionalized account of a morbidly obese bear named Allen and a resilient child, Henny, who forms an unlikely bond with the captive animal, reflecting on themes of nature, independence, and abandonment. The second story, “Recipes for Radicals,” delves into the COVID-19 pandemic with a diary-like structure and an underlying theme of confronting moral injustices and the complexities of justice and revenge. In “The Wild Thing,” the protagonist, Meredith, …

Masks And Mirrors: The Authorial Selfhood Of J.M. Coetzee’S Elizabeth Costello And Susan Barton, Emily R. Peters

Legacy Theses & Dissertations (2009 - 2024)

This thesis examines the authorial characters of Elizabeth Costello, from the novel of thesame name, and Susan Barton, the protagonist of the novel “Foe,” both authored by South African-born writer J. M. Coetzee, through the ontological concept of the Heideggerian Dasein. Both fictional characters contend with the issues of alienation of Self and the struggle for reciprocal Othering imposed upon them by the social constructs of their authorhood and struggle for an authentic self, specifically in view of the performative nature of their gendered roles and the issue of Coetzee’s male authorhood.

Distinguishing Between Living And Dead Plant Material From The Red Spruce Using Atr Ft-Ir Spectroscopy, Bailey Ann Hoplight

Legacy Theses & Dissertations (2009 - 2024)

Spectroscopic methods have recently been used to analyze plant species and maturation. However, there is a lack of research into employing spectroscopy for distinguishing living plant material and dead plant material, which is important for the agriculture and environmental health fields. Here in this study, we have shown the potential of ATR-FT IR (Attenuated total reflectance Fourier transformed infrared spectroscopy) to classify plant materials as living or dead through the help of multivariate statistical analysis methods. Plant samples were from the roots and needles of picea rubens, more commonly known as the red spruce tree. The samples were classified by …

An Examination Of School Resource Officers' Self-Perception Of Role, Student Encounters And Duties, Alexandra Swanty

Master's Theses

As the rates of school shootings and school violence rise, the effectiveness of school resource officers (SROs) has come into question. As of now, there is no nationwide standard for the role and duties of school resource officers. Therefore, these differ from state to state and even school district to school district. One variable that had yet to be examined was the impact that location has on the roles of school resource officers. From this, three different school resource officer roles were identified: teaching-based role, community-based role, and law enforcement-based role. To determine the relationship between these variables, an online …

Governmental And Semi-Governmental Federal Charitable Entities, Ellen P. Aprill

UC Law Journal

The standard view of the relationship between government and the nonprofit charitable sector treats them as separate and distinct. But they are not. Numerous federal agencies have statutory authority to receive tax-deductible charitable deductions. Their ability to do so, however, undermines the oversight accomplished through the constitutionally mandated appropriations process. Congress has also created many nonprofit tax-exempt organizations. These entities enjoy flexibility as to fundraising, investment, and spending that government agencies lack. However, they avoid the accountability that various federal statutes impose on government agencies, on the one hand, and that state nonprofit laws accomplish for private nonprofit organizations, on …

Interstate Immunity And The Uncompleted Constitution, Mark D. Rosen

UC Law Journal

In a recent decision, the Supreme Court held that “the founding generation took as a given” that states would be constitutionally immune to suit in the courts of sister states, overruling an earlier ruling that interstate immunity is governed by state law. This Article rejects both approaches, showing that interstate immunity was unaddressed by the original Constitution and the Eleventh Amendment. But though interstate immunity is what this Article calls a “constitutional omission,” what ultimately fills it must be federal law. Filling in a constitutional omission necessarily requires a choice among options—what philosophers call an exercise of agency. But the …

The New Fourth Era Of American Religious Freedom, John Witte Jr., Eric Wang

UC Law Journal

The U.S. Supreme Court has entered decisively into a new fourth era of American religious freedom. In the first era, from 1776 to 1940, the Court largely left governance of religious freedom to the individual states and did little to enforce the First Amendment Religion Clauses. In the second era, from 1940 to 1990, the Court “incorporated” the First Amendment into the Fourteenth Amendment Due Process Clause and applied both a strong Free Exercise Clause and a strong Establishment Clause against federal, state, and local governments alike. In the third era, from the mid-1980s to 2010, the Court softened the …

Fostering A Sense Of Wonder: Promoting Experiential Learning Through Outdoor Discoveries On The Coast Of Maine, Joslyn Primicias

Honors Theses
