Polymer-Based And Functionalized 3d Microelectrode Array (Mea) Biosensors, Nilab Azim

Electronic Theses and Dissertations, 2020-2023

Microphysiological systems are three-dimensional (3D) in vitro systems that recapitulate crucial biological aspects of cell heterogeneity and native tissue architecture by mimicking complex structures that are impossible in two-dimensional (2D) cell cultures. Microelectrode arrays (MEAs) are biosensors used to spatially and temporally monitor the activity of microphysiological systems by transducing cellular signals into electronic signals to provide quantitative data on the in vitro system. Conventional MEAs are typically planar in nature, however, 3D MEAs offer several advantages such as better simulation of an in vivo cellular environment and improved signal-to-noise ratio and cell-electrode coupling. MEA fabrication utilizing traditional cleanroom methods …

Relations Between Sexual And Gender Minority Stress, Personal Hardiness, And Psychological Stress In Emerging Adulthood: Examining Indirect Effects Via Human-Animal Interaction, Camie A. Tomlinson, Jennifer L. Murphy, Angela Matijczak, Shelby E. Mcdonald

Graduate Research Posters

Introduction: Although there is emerging evidence that companion animals are important sources of comfort and support for many LGBTQ+ (lesbian, gay, bisexual, transgender and other sexual and gender minority identities) individuals, little is known about the interplay between sexual and gender minority (SGM) stress, human-animal interaction (HAI), and psychological adjustment in this population. To address this gap in the literature, the current study examined the role of HAI in relations between SGM stress (i.e., microaggressions, victimization) and psychological adjustment (i.e., self-efficacy, psychological stress) during emerging adulthood.

Methods: Our sample included LGBTQ+ young adults between the ages of 18 and 21 …

Epigenetic States Regulate Tumor Aggressiveness And Response To Targeted Therapies In Lung Adenocarcinoma, Fan Chen

Theses and Dissertations--Toxicology and Cancer Biology

Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide, 85% of which are lung adenocarcinomas (LUAD). Although molecular studies of NSCLC identified targetable mutations of some oncogenes including BRAF, EGFR and ALK, no targeted therapies exist for most cases. Cancer epigenetics is the study of epigenetic modifications, including histone modifications, that control gene expression in cancer. Recent advances have revealed numerous epigenetic abnormalities in human cancers, and targeting epigenetic regulators could be effective at reversing dysregulated epigenetic programs or driving sensitivity to other targeted therapies.

Inhibitors of the histone methyltransferase EZH2 have recently been approved as …

The Tumor Suppressor Par-4 Regulates Hypertrophic Obesity, Nathalia Araujo

Theses and Dissertations--Toxicology and Cancer Biology

Prostate Apoptosis Response-4 (Par-4) is a tumor suppressor ubiquitously expressed in all tissues and able to selectively induce apoptosis in cancer cells. Although well established in the context of cancer, relatively little is known about the function of Par-4 in the healthy and non-tumorigenic context. Observations from our lab showed that Par-4 knockout mouse lines were obese and displayed adipocyte hypertrophy under a normal chow diet when compared to Par-4 wild-type mice. These Par-4 knockout mice exhibited hepatic steatosis and hyperinsulinemia as secondary consequences of obesity. Par-4 knockout mice displayed increased intestinal dietary fat absorption and its subsequent storage in …

Mechanisms Of Cadmium-Induced And Epidermal Growth Factor Receptor Mutation-Driven Lung Tumorigenesis, Hsuan-Pei Lin

Theses and Dissertations--Toxicology and Cancer Biology

Cadmium (Cd) is a ubiquitous pollutant in the environment and a known carcinogen for lung cancer. Cd has been shown to act as a weak mutagen, which suggests that it may exert tumorigenic effect through non-genotoxic ways, such as epigenetic mechanisms. The goal of this project is to investigate the mechanisms of Cd carcinogenesis focusing on the role of lncRNA dysregulations. The Cd-exposed cells formed significantly more colonies in soft agar, displayed cancer stem cell (CSC)-like property and formed tumors in nude mice. Mechanistically, the lncRNA microarray analysis revealed that chronic Cd exposure dysregulates lncRNA expressions. Q-PCR analysis confirmed the …

Delineating The Role Of Fatty Acid Metabolism To Improve Therapeutic Strategies For Colorectal Cancer, James Drury

Theses and Dissertations--Toxicology and Cancer Biology

Colorectal cancer (CRC) remains a leading cause of cancer-related deaths in the world, comprising over 1 million new cases each year and over 500,000 deaths. CRC, when detected at an early stage of disease development, can be effectively treated, with a 5-year survival rate of over 90%. Such standard treatments include surgical resection of the primary tumor in combination with adjuvant chemotherapy. However, even with advancements in surgical procedures and chemotherapeutic targets, when CRC progresses to a more advance stage, the 5-year survival rate decreases significantly to just under 14%. This stark decrease in patient survival rate can be directly …

Science-Based Regulation Of Pharmacological Substances In Competition Horses, Jacob Machin

Theses and Dissertations--Toxicology and Cancer Biology

Current testing methodologies within equine forensic toxicology focus on arbitrary thresholds and zero-tolerance policy. Modern analytical chemistry’s limits of detection are low enough that oftentimes femtogram-per-milliliter amounts of a substance can readily be identified in both blood and urine of a horse. For most pharmacologically relevant compounds, these concentrations have no relevance to pharmacological effect. It is therefore crucial that testing methodologies to determine appropriate thresholds and cut-offs be developed that are driven by biological activity rather than arbitrary limits of detection. This dissertation looks to address this by suggesting a system of calculated Effective Plasma Concentrations by which a …

Civil Rights Law—Inclusion Of Emotional Support Animals As Service Animals Under The Ada: Creating The Right To Use Dogs To Assist People Living With Mental Health Issues, Amanda M. Foster

Western New England Law Review

The use of emotional support animals to alleviate or mitigate symptoms associated with mental health issues has been a topic of debate since its inception. On one hand, there is the community of people who have expressed a need to use support animals to help them to participate in society, including while traveling by airplane. On the other hand, the Department of Transportation has had to assess whether allowing support animals on airplanes would pose a direct threat to the safety or health of others.

In most contexts, support animals are not treated as service animals, so therein lies substantial …

The Effect Of The Interaction Of Exercise Training And Isolation On The Serotonergic System Of App/Ps1 Mice, Bailey J. Dansby

Graduate Theses/Dissertations

Alzheimer’s disease (AD) is a complex neurodegenerative disease that is characterized by the deposition of amyloid beta (Ab) peptides and, consecutively, by a loss of memory and cognitive functions. The amyloid cascade hypothesis suggests that Ab deposition is the main pathogenic of AD. There is evidence that both changes in production and clearance of Ab may be involved in AD pathology. Past studies have shown that exercise training leads to an upregulation in proteins directly involved with Ab clearance. Chronic stress is thought to exacerbate AD pathology by increasing production of Ab. Studies have also demonstrated a link between serotonin …

Climate Change And Innovation In Brazil: Threats And Opportunities, Gabriel Wedy, Cacia Pimentel

Sabin Center for Climate Change Law

In recent decades, Brazil has adopted a political approach focused on maintaining economic stability and consolidating inclusive social policies. However, despite repeated attempts, little progress has been made in overcoming difficulties within the country and making Brazil more competitive in the global market. Nevertheless, there seems to be an awakening and a certain consensus among scholars of Brazilian problems that the expected inclusive economic growth cycle may be achieved if Brazil invests in enhancing the bioeconomy business environment through bioenergy and innovation.

The actual crisis is fast–tracking two major transformations at the global level: the energy transition and the information …

Comic Narrative Expression And Aesthetics: From Print To Webtoons, Kai Shao

Selected Full-Text Master Theses 2021-

Comics are a unique way for artists to tell stories. The production and distribution of comics are affected by technological development. In this process, comics formed their special narrative language and aesthetic system. With the development of digital technology and portable devices, comics as a medium is undergoing major transformations towards digitization. However, most digital comics still abide by the format and layout that traditional printed comics have used for so long. Although some platforms have tried to innovate their design and layout to be delivered digitally, not all of these attempts have been successful. Webtoon originated in South Korea …

Night Of Awakening: Strength And Empowerment In The Young Adult Fiction Genre, Shelby Ann Davis

Undergraduate Honors Theses

The Young Adult Fantasy genre is often written off as a useless, or immature form of writing. However, there are studies that prove that this specific genre is not only engaging, but it is also empowering for young readers. By writing toward adolescent readers, authors are able to promote various ways in which their characters adjust or interact with their surroundings, which also influences their readers’ self and social awareness. By representing feminist perspectives and depicting the effects of trauma, YA literature fosters progressive social change and conveys the importance of mental health. In writing my own novel, The Night …

The Public's Perception Of Medical Ultrasound, Bailey Klein, Michelle Anderson

Student Research Poster Presentations 2021

Ultrasound (sonography) is a primary imaging modality predominantly used in the Diagnostic Radiology department to aid in the findings of internal pathological conditions. Sonography has been used for medical diagnosis since the early 1970’s; however, in comparison to other imaging modalities, it is relatively young and evolving. Since Ian Donald’s discovery in obstetrical ultrasound, there has been a significant growth in Maternal and Fetal Medicine as well as an explosion in the use of non-medical obstetrical imaging, better known as keepsake or entertainment ultrasound. Unlike all other imaging examinations, in obstetrics, family members accompany the patient for viewing where the …

Improving Matching And Classification Through Deep Learning Of Structure And Varying Illumination, Sarah Braeger

Electronic Theses and Dissertations, 2020-2023

Convolutional networks have driven major advances in computer vision in recent years. The design of deep architectures, loss functions, and the curation of large, diverse datasets have furthered progress in many applied computer vision tasks. How data is represented to a network guides feature discovery and must be carefully considered in order to maximize performance on any applied task. We introduce novel input representations and associated architectural techniques to better utilize them such as complementary loss terms and network structure. We demonstrate the impact of these approaches on classification and matching tasks which involve shape and varied illumination. We show …

Mechanics Of Low Dimensional Biomimetic Scale Metamaterials, Hossein Ebrahimi

Electronic Theses and Dissertations, 2020-2023

Combination of topology and material could play an important role in giving rise to nontraditional behavior in mechanical structures and is a typical strategy in nature. Topology is concerned with the geometrical and spatial properties of the objects, which are preserved under continues mechanical deformation of the object such as stretching, bending, twisting, etc. In this work, we focus on structures based on fish scale inspired surface topology. The utilized idea for surface topology is a bioinspired design on the substrate of biological scale-covered systems. Scales are a path breaking evolutionary adaptation that accompanied vertebrate evolution for the past 500 …

Subverting Title Ix, Emily Suski

Faculty Publications

Thousands of sexual assaults happen to children in K–12 public schools each year, but the federal courts regularly allow the schools to do almost nothing in response. Title IX exists to ensure that public schools protect students from sexual assaults, harassment, and other forms of sex discrimination. Yet, the federal courts’ interpretations of Title IX drain its power. The Supreme Court has said that public schools will be liable under Title IX if they act with deliberate indifference to known sexual harassment. The Court’s explanation of “deliberate indifference” proscribes schools’ responses to sexual harassment that indirectly cause or make students …

Black Urban Ecologies And Structural Extermination, Etienne C. Toussaint

Faculty Publications

Residents of low-income, metropolitan communities across the United States frequently live in “food apartheid” neighborhoods—areas with limited access to nutrient-rich and fresh food. Local government law scholars, poverty law scholars, and political theorists have long argued that structural racism embedded in America’s political economy influences the uneven development of such Black urban ecologies. Accordingly, food justice scholars have called for local governments to develop urban agricultural markets that combat racism in global corporatized food systems by localizing food development. These demands have only amplified during the COVID-19 pandemic, which has ravaged Black communities where residents suffer from preexisting health conditions …
