LSU New Orleans Theses and Dissertations

Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a complex neurodevelopmental disorder associated with serious medical, cognitive, and psychiatric conditions, including significantly elevated risk for obsessive-compulsive (OCD) and/or schizophrenia spectrum disorders (SCZ). The cortico-striato-thalamo-cortical (CSTC) neural circuit is critical for cognitive and emotional processing. Dysfunction of the CSTC circuit is implicated in the etiopathology of both OCD and SCZ but has not been specifically examined in individuals with 22q11.2DS. This study used structural magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI), along with standardized psychological and cognitive measures, to investigate atypical morphometry and white matter connectivity within CSTC-related brain regions in …

Mechanisms Of Behavioral Change In Hosts Of Toxoplasma Gondii: A Review, Olivia Grimsley

Senior Honors Theses

The parasite Toxoplasma gondii is a highly ubiquitous parasite that latently infects an estimated 33% percent of the global population. Toxoplasmosis is of obvious clinical significance due to the extremely high risks to the unborn who contract it congenitally. Less attention has been given to a more subtle aspect of latent infection, which is the behavioral alterations that are commonly experienced by those who contract the parasite. Infected individuals commonly display a variety of altered behaviors, such as increased aggression and risk-seeking behaviors, depression, higher tendency towards suicide and self-directed violence, a loss of fear response, and a greatly increased …

Movement Ecology Of Sandhills Chub, A Carolina Endemic, Zachary Adam Ramsey

Electronic Theses and Dissertations

Fish movement studies have traditionally focused on species that support commercial and recreational fisheries, but recently more focus has been given to non-game, stream fishes because of their recognized importance in maintaining biodiversity within these ecosystems. Stream fish movement is described as being “restricted” and following a leptokurtic distribution via diffusive spread related to environmental and biological factors. Many studies of stream fish movement ecology in North America have occurred in high-gradient streams with coarse substrate in mountains or in streams of the interior plains. Sandhills streams of the southeastern USA are characterized as warm-water, low gradient, and dominated by …

Heterotopias Of Confinement: Zoo Architecture And The Loss Of Elephant Agency, Clayton Gill Beasley

Electronic Theses and Dissertations

Zoos functions as a site where human-animal relationships are structured through built environments that mediate control and representation. This study examines zoos as heterotopias—spaces where power and surveillance are negotiated between human observers and captive nonhuman animals. While zoos are often framed as spaces of conservation and education, their architectural design reinforces hierarchies of observation and confinement, shaping both human perceptions of nature and the lived experiences of nonhuman animals. This research focuses on Asian elephants as a critical species within this framework, exploring how their captivity illuminates tensions between human-imposed structures and nonhuman autonomy. Drawing from theories of heterotopia, …

Assessing Sleep Quality In A Preclinical Model Of Low Back Pain Through Novel Noninvasive Methods, Lydia C. Saltz

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Chronic low back pain (LBP) has widespread negative impacts on quality of life. Current treatments for chronic LBP fail to provide long-term efficacy and motivate the need to understand key drivers of poor patient outcomes. Mounting evidence indicates that sleep disturbances and chronic LBP have a strong reciprocal relationship. Women may be particularly vulnerable to the negative impacts of the sleep-pain axis, exhibiting greater prevalence in both conditions. However, the relationship between sleep, pain, and sex remains understudied. Preclinical models can be used to parse out characteristic sleep features that degrade with pain, which can be further broken out by …

The Relationship Between Oxidative Stress And Partner Opposition In Conflict Resolution, Jenna Thomas

Biological Sciences Undergraduate Honors Theses

Given the inevitability of conflict in romantic relationships, understanding its biological impact is crucial for developing conflict resolution strategies that promote physical health. While many studies highlight relationship conflict’s negative effects on bodily systems, few examine how specific facets of conflict, such as opposition, impact the body. Partner opposition may contribute to oxidative stress, a biological marker associated with poor physical health, by activating the amygdala. This study investigated the association between partner opposition and oxidative stress in 126 couples expecting their first child. Participants attended a lab session where problem-solving discussions were recorded to assess oppositional behavior and urine …

A Nano-Scale Approach To Controlled Apoptosis In Brain Cancer Through Magneto-Mechanical Actuation, Sakura Rieck

Biological Sciences Undergraduate Honors Theses

In this study, we investigate the effects of cell therapy and magneto-mechanical actuation (MMA) to treat glioblastoma (U87). MMA approach employs super low-frequency alternating magnetic fields (AMF) to actuate intracellular PEGylated superparamagnetic iron oxide nanoparticles (PEG-SPIONs). Magnetic forces are translated into mechanical agitation on PEG-SPIONs, which can disrupt key cellular components. We explored two ways in which the MMA approach can be used to combat cancer growth. First, we investigated MMA directly in U87 cells. Preliminary observations indicate that PEG-SPIONs are intracellularly taken up by the U87 cells via micropinocytosis. Cell-counting kit-8 toxicity assays revealed a cytotoxic effect of MMA …

Investigating The Effects Of Sod1 Knockout On Oxidative Stress And Stress Coping Styles In Zebrafish Using Crispr Technology, Tai Prauner, Ryan Wong

Theses/Capstones/Creative Projects

Reactive oxygen species are byproducts of cellular metabolism that, when not efficiently neutralized, can damage DNA, proteins, and lipids. Superoxide dismutase 1 (SOD1) is an antioxidant enzyme that converts superoxide radicals into less harmful molecules. While its molecular function is well documented, the role of SOD1 in shaping stress-related behavior remains underexplored. This project aimed to establish foundational tools for studying the behavioral impact of SOD1 knockout across proactive and reactive stress-coping styles in zebrafish.

To support future gene-editing experiments, microinjection and breeding protocols were refined across wildtype AB, proactive, and reactive zebrafish lines. No embryos were injected with CRISPR-Cas9 …

Firefighters' Perceived Effectiveness Of Peer Support For Job-Related Stressors, Camryn M. Travis

Senior Honors Projects

Firefighters experience immense job-related stress. Firefighters can respond to hundreds of traumatic calls or critical incidents throughout their careers. Witnessing a critical incident can be highly stressful and mentally taxing. Therefore, some fire departments offer mental health resources such as Critical Incident Stress Management/Debriefing (CISM/D) and Peer-group support to help firefighters cope with stressful incidents. Additionally, firefighters may seek professional mental health treatment. To investigate firefighters’ perceptions regarding the effectiveness of these resources, an anonymous survey of Rhode Island firefighters was conducted. The sample included 51 firefighters (n = 51), was mostly male (90.2%), and self-identified as predominantly white (94.1%) …

Gender And Race Stigma Consciousness Denialism And Reactions To Race And Gender Measures, Valerie Partida, Alicia Sylvester, Magel Baker

Celebrating Scholarship and Creativity Day (2018-)
