Sanctuary: Counter-Oppressive Relationships With Farmed Animals As An Ecopsychological Imperative, Kelsey Bomboy

The International Journal of Ecopsychology (IJE)

Consumers are intentionally shielded from and often misled about the process of breeding, raising, and slaughtering animals for consumption. By confining most farmed animals to warehouses in rural areas while the majority of humans are sequestered in urban areas, we have effectively created a world where humans do not have to contend with the sense of interconnectedness that arises when witnessing and being witnessed by a farmed animal. Within industrial slaughterhouses, the physical act of killing is minimized to just a fraction of the workers, so that even those who are responsible for rendering a once living being will never …

If Pets Are Family: Pet Loss And The Need For Grief Equity In One Health, Michele L. Whitney

Journal of One Health Systems

One Health frameworks increasingly recognize pets as integral to human health and well-being. However, these models often overlook the health and equity implications of pet loss. Culturally mediated grief experiences following pet bereavement represent a critical grief equity gap in One Health systems. Drawing on findings from a qualitative study of African American adults who experienced pet loss, along with existing literature, this Viewpoint highlights how pet loss is not only an emotional experience but also a socially structured one shaped by cultural norms, social recognition, and access to support. These dynamics contribute to inequities in how grief is experienced …

Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez

Psychology ETDs

Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …

Feeding The Future: Prenatal Dietary Effects On Offspring Neurodevelopment, Emma Whatley

Senior Honors Theses

This study examined the effects of prenatal Western (WD) and Mediterranean (MD) diets on offspring metabolic, cognitive, and neurobiological outcomes in a preclinical mouse model. Working and long-term memory performance, dendritic morphology, and gene expression were assessed using behavioural tests (CAL, YMRM, WM) and Golgi-Cox analyses. Behavioural effects were minimal, with female MD offspring showing improved memory performance under standard conditions. Metabolic findings showed effects on body weight and blood glucose. Dendritic morphology was largely unchanged; however, subtle, sex-specific differences were observed. Differential gene expression between MD and WD suggests a role for future environmental stressors. Prenatal diet affects molecular …

Neuroprotective Effects Of Prophylactic Brivaracetam On Memory And Anxiety Following Traumatic Brain Injury, Sofia Dumic

Theses and Dissertations

Prophylactic brivaracetam (BRV) was evaluated in a rat TBI model for effects on behavior and serum tau. BRV reduced anxiety-like behavior with optimal dose-dependent effects at 2.1mg/kg, but did not affect working memory. Serum tau was detectable early post-injury, supporting its use as a biomarker.

Perinatal Inflammation And Oxidative Stress Alter Adult Rat (Rattus Norvegicus) Motor Behavior, Alexander Young

Honors College Theses

Recent evidence in comparative animal models suggests that early life exposure to elevated inflammation (via LPS exposure) and oxidative stress (via acetaminophen exposure) may synergistically interact to alter typical neurodevelopmental trajectories, resulting in lasting effects on both behavior and gut-brain neurochemistry. The current study observed emotional and motor behaviors and collected fecal-boli to measure Tyrosine (TE) levels in male and female Long-Evans (Rattus norvegicus) rats. Subjects were either treated with [1] saline [2] lipopolysaccharide (LPS) to introduce an inflammatory state, [3] acetaminophen (APAP) to introduce oxidative stress, or [4] a dual-hit of both LPS + APAP on postnatal day (PD) …

The Immune Hangover: Understanding The Influence Of Alcohol Use, Abstinence, And Post-Abstinence Drinking On Monocyte Plasticity, Madison B. Blanton

Theses and Dissertations--Pharmacy

Alcohol consumption is widespread in the United States, with 80% of individuals aged 12 and older reporting alcohol use and 1-in-4 engaging in risky drinking behaviors. Alcohol misuse heightens susceptibility to infections and delays wound healing, indicating a disrupted immune system. Previous studies show alcohol rewires immune cells, especially monocytes and macrophages, which play critical roles in tissue homeostasis and host defense.

Using a rhesus macaque model of ethanol self-administration, we demonstrate that after 6-months of drinking, monocytes exhibit decreased cytokine production and significant transcriptomic changes, indicating a hypo-inflammatory state. In contrast, 12-months of chronic alcohol use induces hyperinflammatory responses, …

Invasion Of Microplastics Into The Reproductive Tissues Of Feral And Domestic Felines, Emma K. Quade

Honors Undergraduate Theses

Although plastics have many useful properties in modern society, once these materials are introduced into the environment, they can cause extensive damage. Following degradation into microplastics (MP), plastic particles less than 5 mm in size, these contaminants can make their way into a variety of different environments and organisms. There are many studies that have investigated the prevalence of MP in marine environments, but fewer studies have looked into terrestrial systems, and even less that have focused on contamination in companion animals. This study sought to investigate the invasion of MP into the reproductive tissues of felines, Felis catus, …

Two Major Ontario Hospital Labs Bought Research Dogs From U.S. Breeder With Troubled Pastdogs Bred For Scientific And Medical Testing Suffer Abuse As The Scientific Industry Increasingly Turns To Alternatives For Research., Allison Hunter, Mary Beech, Sami Marshak, Kate Morano

Capstones

The purpose-bred dog breeding industry for research is little known. Each year, thousands of dogs are bred for scientific and medical testing, supplied to research facilities by a handful of major commercial breeders. But gaps in enforcement and regulation have allowed abuses to persist, even as the industry increasingly turns to alternatives to animal testing. Animal rights advocates have been decrying the treatment of these dogs. A federal Inspector General report found lax oversight of the industry, raising further concerns about how dogs are treated. This story was reported in collaboration with the Investigative Journalism Bureau, based in Toronto, and …

Developmental Lead Exposure And Aggression In Male Rats: Influences Of Maternal Care And Environmental Enrichment, Shamaila Zafar, Courtney K. Williams, Jaehyun Joo, Blanca E. Himes, Jay S. Schneider

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Developmental lead (Pb) exposure results in a variety of cognitive deficits and behavioral issues including increased antisocial behavior and aggression. This study investigated the effect of developmental Pb exposure on aggression and violent behavior in male rats and the potential modulatory influences of quality of maternal care and enriched/non-enriched housing conditions. Long-Evans male rats with or without Pb exposure (perinatal or early postnatal) from low or high maternal care mothers (based on amounts of licking/grooming and arched- back nursing) were randomly assigned to live in enriched or non-enriched environments at weaning. At post- natal day 120–190, offensive aggression was assessed …

Field Journal: The Excluded Middle, Carrie E. Kouts

Masters Theses

What does it look like to engage with organisms and landscapes at the periphery of anthropocentric value structures? How does one break the internalized myth that the “built” environment is excluded from the natural world? When does a hyper-mobile and hyper-commodified society confront the exponential crisis of animal death? Within this series of journal entries, field notes, collection observations, weird prose, and sensory musings, one will find questions on the nature of being human and the complex narratives of care we encounter in a world shared with more-than-humans. Each handwritten vignette and photograph from daily life weaves a non-linear and …

Applying Supervision To Animal Assisted Therapy: Using The Integrative Development Model, Rachel W. Rachlinski, Kelli A. Mcfarland

Journal of Counselor Preparation and Supervision

A study conducted by Hartwig and Smelser (2018) reported 91.7% of clinicians being aware of animal assisted therapy (AAT) who agree it is a legitimate treatment model. However, 57% of respondents expressed interest in receiving AAT training. Although published standards and competencies published by ACA and IAHAIO indicate the requirement for clinical supervision when implementing AAT, research does not address supervision protocols for AAT. This manuscript suggests a protocol for supervising the implementation of AAT. The consequence of untrained supervisors is the potential harm to the well-being of the client as well as the clinician and the animal. As such, …

It focuses on three types of animal advocacy: 1) stray animal welfare, 2) wildlife conservation, and 3) farmed animal welfare. The paper critically analyses current practices and trends in each of these areas, highlighting the main challenges and opportunities facing the growth of the movement. Our research draws on insights from interviews with active animal welfare organizations, situating their practical experiences, daily operational struggles, as well as instances of success, within Egypt’s wider socio-economic …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave

Dissertations and Theses (Open Access)

Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …

A Form-Fitting Model For The Simulation Of Traumatic Brain Injury In Zebrafish, Abigail Armstrong

Williams Honors College, Honors Research Projects

Developing a model to study traumatic brain injury (TBI) is important as it allows for the better understanding of mechanisms underlying the disease to develop effective treatments and other strategies. Creating a realistic simulation of TBI, permits the research of different types of impacts and severities that can be seen in brain function and structure. The simulation is also valuable for monitoring progression of injuries over time and developing personalized treatment plans. Zebrafish, in particular, are prime candidates given their status as model organisms, affordability, and ease of direct observation in the research setting. Overall, efficient and accurate TBI models …

Effects Of Perinatal Exposure To Lipopolysaccharide And Acetaminophen On Learning In Adult Long-Evans Rats, Lucy A. Sivils

College of Graduate Studies: Theses & Dissertations

The present study investigated the individual and combined effects of elevated perinatal inflammation, oxidative stress caused by acetaminophen (APAP) exposure, or elevated inflammation and oxidative stress on adult learning behaviors in Long-Evans rats. While prior studies have examined these factors independently, the combined effects of inflammation and oxidative stress via APAP exposure during early development on learning-related behaviors remain unexplored. The present research aimed to address this gap by the analysis of potential long-term neurodevelopmental consequences of lipopolysaccharide (LPS)-induced inflammation and APAP-induced oxidative stress. LPS, APAP, or LPS + APAP was administered during the perinatal period: postnatal days (PD) 9, …

Administering Tolfenamic Acid To Gilts And Sows Before Artificial Insemination Did Not Improve Litter Size But Tended To Reduce Post-Service Serum Prostaglandin F2Α Levels, Pachara Pearodwong, Nithitad Jiebna, Padet Tummaruk

The Thai Journal of Veterinary Medicine

This study examined the impact of intramuscular administration of tolfenamic acid 10 min before artificial insemination (AI) on serum PGF2α levels and reproductive performance in gilts and sows. In Experiment I, 20 gilts were divided into two groups: control (n = 10) and treatment (n = 10). Serum samples were collected 30 min before and after insemination to measure PGF2α levels. In Experiment II, 175 gilts and sows were divided into control (25 gilts and 56 sows) and treatment (16 gilts and 78 sows) groups. In both experiments, the treatment group received an intramuscular injection of 2 mg/kg tolfenamic acid …

The Left Ventricle Under Stress: Exploring The Impact Of Gestational Stress On Postpartum Cardiovascular Health, Archana Ramesh

Senior Theses

A woman’s cardiovascular system undergoes several changes to equip it for the physiological demands of pregnancy. The left ventricle (LV) is most susceptible to changes such as increased cardiac output and workload because it is the primary chamber in the heart that pumps oxygenated blood to the entire body. Some mothers may be unable to cope with the physiological demands, and ventricular hypertrophy, along with other cardiac remodeling that takes place during pregnancy, may bring light to underlying cardiovascular disease (CVD). The peripartum period often comes with heightened stress, disproportionately for certain populations, and this stress has been linked with …

The Experience Of Pet Ownership In Transitional Housing, Kathryn Holden Ots, Susan Macdermott Otd, Otr/L

Summer 2024 OTD Capstone Symposium

25% of people experiencing homelessness have pets, but few transitional housing programs allow pets (Rhoades et al., 2015); therefore, there is a gap in the literature about the experience of pet ownership during the transitional housing process. This study aimed to explore pet owners' experiences at a transitional housing site in San Diego County. The student interviewed two current dog owners and four recent dog owners. All participants prioritized their pets because it was their strongest relationship. The prioritization of their dogs positively and negatively influenced occupational engagement. While receiving services, owners experienced consequences when separated from their dogs, including …

Enhancing The Visual Environment Of Indoor Housed Laboratory Cynomolgus Macaques (Macaca Fascicularis) To Reduce Stress And Maladaptive Behavior, Jeannine C. Rodgers

Theses and Dissertations

Nonhuman primates housed in indoor laboratory environments are generally exposed to nondescript background visual stimuli. This environment is not ideal for species whose primary sensory modality is visual. To provide a more naturalistic visual environment that would potentially improve their welfare, this study assessed the efficacy of a passive natural visual stimulus in the reduction of stress and stereotypy and agonistic behaviors in a cohort of four (2 male, 2 female) Cynomolgus macaques (Macaca fascicularis) housed in an indoor laboratory facility in New York City. The macaques were exposed to four different videos depicting scenes of natural landscapes that were …

Microplastic Accumulation In The Marsh Periwinkle (Littoraria Irrorata), Sarah Keaton, Hannah Lukhard, Eli Windy, Manar Hasan

DePaul Discoveries

Contamination of oceans by microplastics (mm) currently poses a major threat to aquatic and terrestrial ecosystems worldwide. Recent attention towards this issue has raised questions about the extent to which microplastics have accumulated in the environment, and has led to an increase in studies on the effects of microplastics in various organisms. However, levels of contamination in protected natural areas are still largely unexplored, yet can offer an important empirical perspective on the issue. In addition, little is known about the potential effects of microplastics on behavior in the field. This research was conducted within the protected ACE Basin National …

Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha

DePaul Discoveries

Ontogeny is described as the history of an organism through its lifetime including development, growth, and allometry. The ontogenetic approach in cranial dimensions has proved useful in interpreting evolutionary patterns. Among the largest Didelphidae family of Neotropical marsupials, the species of Gracilinanus agilis and Cryptonanus chacoensis are poorly known. In this study, we address three questions; Is there sexual dimorphism in these species? What is the pattern of allometry? Which allometric patterns best describe the patterns in the skull and mandible? We applied geometric morphometrics to describe and test these differences using MorphoJ. A discriminant function analysis was performed to …

A Comprehensive Analysis Of How Pet Ownership Impacts The Experiences And Well-Being Of Homeless Individuals, Alexandra G. Watson, Nancy A. Dreschel

People and Animals: The International Journal of Research and Practice

This paper conducts a thorough examination of the relationship between pet ownership and homelessness. In a context where homelessness in the United States is a growing concern, we delve into an aspect that has received little attention: how homeless individuals and their pets interact. Through an extensive review of existing research, this paper aims to uncover the demographic characteristics of homeless pet owners and understand the significant effects of this bond. Our findings reveal that homeless individuals with pets come from diverse backgrounds, including various ages, genders, and racial backgrounds. Their pets provide not only companionship but also emotional support, …

Public Perception Of Service, Therapy, And Emotional Support Animals In A College Setting, Elizabeth Demarse

Honors College Theses

The use of service dogs, emotional support dogs and therapy dogs continues to increase, they are likewise becoming more common on college campuses. However, outside of a 2017 survey into the general population, there is little data into the public’s ability to define these animals and their roles or how negative press affects trust in the legitimacy of these animals. Additionally, no research has been done into how this affects college students despite college campuses frequently being a location where assistance animal ownership is brought into question. An anonymous survey was conducted and distributed online to students at Murray State …

Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson

People and Animals: The International Journal of Research and Practice

As incidences of substance use disorders (SUD) increase in the wake of the COVID-19 pandemic, there is a need for more effective treatment approaches. Further, treatment approaches currently available struggle to retain patients during the period of substance withdrawal in early treatment due to patients’ withdrawal symptoms including increased feelings of anxiety and depression. Withdrawal symptoms have been linked to dysregulated cortisol concentrations present in this period. Psychotherapy incorporating equine interaction (PIE) has emerged in other populations as a treatment that decreases cortisol concentrations and improves treatment retention. The present study investigated the impact of 4 weeks of PIE on …

Birds, Bats And Minds. Tales Of A Revolutionary Scientist: Donald R. Griffin. Volume Three, Carolyn A. Ristau

eBooks

In this three-volume biography, we revisit the life and accomplishments of the revolutionary scientist, Donald R. Griffin. He encountered a lifetime of initial hostile resistance to his ideas and studies; now they are largely accepted. He and a colleague discovered the phenomenon of echolocation used by bats to navigate and capture insects, proposed that birds navigate guided by such cues as the sun and stars, and suggested that animals are likely aware, thinking and feeling beings. Forty interviews with his colleagues and friends help us understand the young emerging scientist and the mature researcher. We learn about his and others’ …

Opioid System's Potential Involvement In Ketamine's Cognitive And Antidepressant-Like Effects In Rats, Fan Zhang

Theses and Dissertations

Depression stands as one of the most pervasive mental health challenges worldwide, including the United States. Conventional antidepressants typically display a delayed onset of therapeutic action (4-8 weeks) and lack efficacy in a substantial portion of patients (over 40% of depressed patients are treatment-resistant). The dissociative anesthetic ketamine, which is a glutamatergic N-methyl-D-aspartate (NMDA) antagonist, has emerged as a promising novel treatment due to its rapid and prolonged antidepressant effects, and it is especially beneficial for treatment-resistant depression. Nevertheless, the precise neurochemical mechanisms underlying ketamine’s antidepressant properties remain elusive, hampering the development of safer and more efficacious treatments. The present …

The Effect Of Mating Pheromone 2,6-Dichlorophenol On Gene Expression In Male Lone Star Ticks (Amblyomma Americanum), Mitchell E. Dyen

Honors Undergraduate Theses

Lone star ticks (Amblyomma americanum) are tick species known for their generalist feeding habits, pursuing blood meals with little preference for specific host species. They are found in the southern and midwestern United States but have been rapidly expanding northward due to climate change and white-tailed deer population expansion. Since they are a zoonotic disease vector, their increased abundance has caused the concurrent increased prevalence of a variety of tick-borne illnesses such as tularemia, heartland virus disease, alpha-gal syndrome, ehrlichiosis, and southern tick-associated rash illness (STARI), which effect both humans and animals alike. This increased prevalence of tick-borne …
