Nicotine Self-Administration And The Impacts On Medial Habenula And Interpeduncular Nucleus Neurophysiology, Nathan Alexander Olszewski

Theses, Dissertations and Capstones

Nicotine use is a tremendous public health issue in the United States, with over 23 million people being dependent on the substance. Low cessation rates associated with nicotine use are largely attributed to the withdrawal and craving symptoms that occur after abstinence of use from nicotine. The medial habenula (MHb) and interpeduncular nucleus (IPN) are two brain regions heavily associated and linked with nicotine withdrawal. Here, I sought to understand how these brain regions are altered in their physiology during nicotine intake. Utilizing E-Vape self-administration, mice were first taught to selfadminister nicotine of various, clinically relevant, dosages which correlate to …

Ventilation-Perfusion Scan: A Functional Imaging Approach To Regional Lung Disease In Primary Ciliary Dyskinesia, Gabriel Román-Ríos, Gabriel Rosario-Ortiz, Marcos J Ramos-Benitez, Ricardo A Mosquera, Wilfredo De Jesús-Rojas

Faculty, Staff and Student Publications

Introduction: As a rare genetic disorder defined by defective ciliary motility, Primary Ciliary Dyskinesia (PCD) leads to chronic respiratory complications. A founder variant in the RSPH4A [c.921+3_921+6delAAGT] gene, common in Puerto Rico, impairs ciliary function and contributes to progressive lung disease. Today, the clinical value of ventilation/perfusion (V/Q) scans in PCD has not been thoroughly investigated as well as pulmonary function tests (PFTs) and chest imaging. To explore the role and clinical utility of V/Q scans in PCD.

Methods: Retrospective evaluation of pulmonary function tests, chest imaging, and Tc-99m DTPA ventilation and Tc-99m MAA perfusion scans in ten patients with …

Multidisciplinary analysis, including biology, psychology, and sociology, to better understand the compulsory Hookup Culture that exists as a contemporary public health concern among the age group defined as emerging adults. Sexually Transmitted Infections (STIs) diagnoses are steadily rising in the United States and disproportionately affecting college students. Early socialization and current educational resources that contribute to shame and stigma are discussed to explain how lifestyle and social conditions can act as risk factors for individual health outcomes.

Surveillance Of A Novel Vesivirus Discovered In An Urban Mephitis Mephitis Population, Amanda E. Diggins

Honors Theses and Capstones

Caliciviridae is a family of non-enveloped, positive-sense, single stranded RNA viruses, including eleven defined genera that contain important pathogens of humans and animals. Within the Caliciviridae family, the genus Vesiviridae includes feline calicivirus, a leading cause of upper respiratory disease in cats, and vesicular exanthema of swine virus, a historical disease of domestic swine that has now been implicated in several marine mammal vesicular diseases, one of which has been confirmed zoonotic. Urban landscapes create a unique environment for rapid intra- and interspecies transmission of viruses. Clustered resources attract high-density populations of synanthropic wildlife species, increasing spatial overlap and heightening …

Effects Of Dietary Perfluorobutane Sulfonate (Pfbs) On Adipose Tissue, Hannah Olofintuyi, Eric Gato

Honors College Theses

Per- and polyfluoroalkyl substances (PFAS) are chemical substances used in a variety of industrial applications and consumer products. Perfluorobutane sulfonate (PFBS) is often used as a replacement for the more harmful (Perfluoroalkyl sulfonate) PFAS chemicals that have been around longer. It is believed that PFBS does not remain in the body as long as other PFAS compounds; however, there is a rising concern that it has the potential to cause damage to human health. This study focused on understanding how dietary PFBS exposure affects metabolism-related processes in adipose tissues in rats. To accomplish study objectives, Sprague Dawley rats were exposed …

Existential Intelligence: A Survey Across The Ages--As Well As My Ages, Howard Gardner

International Journal of Transpersonal Studies Advance Publication Archive

Written in response to Branton Shearer’s (2026) paper on existential intelligence and existential reasoning, this paper argues that due to the lack of evidence of neural specialization and a developmental trajectory, pondering existential questions is best understood as philosophical thinking, rather than a distinct intelligence. The paper reflects on the status of existential thinking within the author’s framework for multiple intelligences. It traces the criteria originally used to identify the author’s seven intelligences, the later admission of naturalist intelligence, and the provisional consideration of pedagogical and existential intelligences. The paper explains why the labels “spiritual” and “religious” intelligence have been …

Maslow’S Hammer: The Problem Of Scientism And The Philosophy Of Science In Maslow’S Later Work, Richard Grego

International Journal of Transpersonal Studies Advance Publication Archive

This paper examines how Abraham Maslow’s concern with the pervasive intellectual and cultural influence of scientism shaped his philosophy of science and anticipated contemporary discourse on the nature of scientism. Although he never articulated a thorough, formal, or systematic philosophy of science, Maslow’s conception of science’s nature and scope is evident through the course of his work, and it was shaped by his concern with the emerging influence of scientism. The prominent intellectual status science has enjoyed since the Enlightenment has made scientism a powerful influence on postmodern intellectual and popular culture that is currently the subject of a wide …

Pillpetz: A Smarter Way To Encourage Medication Adherence In Children, John H. Begley

CMC Senior Theses

Medication adherence is usually framed as a problem of patient behavior, but this thesis argues that it is equally a problem of design. Children who take daily medication face barriers that adults often do not: developing executive function, dependence on caregivers, shifting school and home routines, privacy concerns, and stigma around being perceived as different. The standard prescription bottle, by contrast, was designed primarily for dispensing efficiency, safety, and accidental ingestion prevention—not for sustained daily use by a developing child.

This thesis proposes PillPetz, a smart pill case and digital companion that uses routine, play, dose confirmation, and caregiver-connected support …

Modulating Oran Nitrate-Reducing Bacteria To Enhance Nitric Oxide Bioavailability As A Therapeutic Target For Atherosclerosis, Donovan C. Davidson

CMC Senior Theses

Atherosclerosis remains the primary driver of global cardiovascular disease, yet clinical interventions are largely restricted to high-cost, invasive procedures only after it has reached a critical stage. Recent research has identified a connection between the oral microbiome and vascular health via the enterosalivary nitrate-nitrite-nitic oxide (NO) pathway. Oral nitrate-reducing bacteria (ONRB) drive the synthesization of NO by reducing dietary nitrate into nitrite, which is then converted into bioavailable NO. NO is a potent vasodilator that maintains endothelial health by suppressing inflammation through inhibiting the expression of adhesion molecules VCAM-1 and ICAM-1. However, this pathway is easily compromised by dysbiotic oral …

Novel Socially Assistive Robot For Alzheimer's And Dementia Home Care; Lived Experiences Of Families, Audrey V. Downs

Honors Theses and Capstones

Informal caregivers for individuals with Alzheimer’s disease and related dementias (ADRD) typically experience high levels of subjective caregiver burden due to strenuous role demands, notably the need to provide frequent reminders and 24/7 monitoring to address care recipient cognitive decline. The purpose of this study was to understand the lived experiences of informal caregivers using a novel Socially Assistive Robot (SAR) to care for individuals with ADRD in a home setting and evaluate SAR impact on caregiver subjective burden. SARs are autonomous, interactive devices that can provide timed reminders and monitor home environments, potentially alleviating some caregiver role demands and …

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) …

Supporting Reentry: An Occupation-Based Approach, Savannah B. Ullyott

Occupational Therapy Capstones

Introduction: Individuals transitioning back into the community following incarceration need holistic care to support a successful reintegration process (National Institute of Justice [NIJ], 2023). There are a variety of supports and barriers to successful reintegration that should be considered when guiding programming for this population, as these individuals often face many challenges when transitioning back into the community (Galletta et al., 2021). Specific supports facilitating successful transitions back into the community includes those of basic or daily needs, often related to housing, employment, transportation, social supports, food security, and access to mental and physical health services (Galletta et al., 2021; …

The Therapy Behind The Tractor: An Occupational Therapists’ Guide For Treating Farmers, Allison Haiby

Occupational Therapy Capstones

Background: Historically, farming is known as a highly laborious job, placing farmers at increased risk for injury. Despite an injury, the farm must continue to be cared for. Although occupational therapy cultivates client-centered care, many therapists have limited knowledge of farming culture and best practice methods to integrate the demands of farming into therapy.

Purpose: The purpose of this scholarly project was to develop an educational guide, Built for the Farm: An Occupation-Based Guide for Therapists Working with Farmers, to support therapists treating farmers. The guide promotes culturally informed, occupation-based strategies to strengthen therapeutic relationships and improve the healthcare experiences …

Baby-Life Balance: Occupational Therapy Strategies To Support The Transition To Motherhood, Morgan Muriel Harshman

Occupational Therapy Capstones

The postpartum period is characterized by significant physical, emotional, and occupational changes that can disrupt daily functioning, routines, and role transition into motherhood (Albanese et al., 2020; Baker et al., 2024). These changes impact a mother’s ability to engage in meaningful daily activities, including self-care, infant care, and participation in family and community roles. Despite these challenges, postpartum care often emphasizes infant health, leaving gaps in support for maternal occupational performance, routine development, and environmental adaptation (Centers for Disease Control and Prevention [CDC], 2023; World Health Organization [WHO], 2022). Occupational therapy is uniquely positioned to address these needs through its …

Tick Lipocalin Triggers Mammalian Igfbp-3-Mediated Apoptosis In Macrophages And Keratinocytes, Krittika Nandy, P. P. Mahesh, Lichao Liu, Daniel E. Sonenshine, Hameeda Sultana, Girish Neelakanta

Biological Sciences Faculty Publications

Ticks secrete several molecules, including lipocalins, in their saliva during blood feeding on a vertebrate host. In this study, we provide novel evidence on the role of Ornithodoros turicata americanus tick lipocalin (Otlip) in modulating cytokine expression and in triggering apoptosis in mammalian macrophages and keratinocytes. The cytokine array analysis revealed significantly increased secretion of insulin-like growth factor-binding protein 3 (IGFBP3) from murine macrophage cell line upon treatment with recombinant Otlip protein (rGST-Otlip) when compared to the secretion noted from cells treated with a control protein (rGST). Similar observation with cytokine protein array analysis was noted when murine macrophages were …

Intermittent Phrenic Afferent Activation Induces Phrenic Motor Plasticity, Nicole M. Popp, Taylor C. Holmes, Elizabeth A. Rozycki, Kristi A. Streeter

Physical Therapy Faculty Research and Publications

Approaches such as electrical stimulation of the phrenic neuromuscular system are currently used in humans to manage breathing impairments. We recently showed that electrical stimulation of the diaphragm muscle induces phrenic afferent-dependent plasticity. These findings highlight the need to better understand the mechanisms of afferent-mediated plasticity to guide and improve the development of novel therapies using electrical stimulation. Here, we tested the hypothesis that intermittent activation of large-diameter phrenic afferents induces phrenic motor plasticity, which, like other forms of plasticity, is pattern sensitive. We delivered inspiratory-triggered electrical stimulation using a narrow pulse width (0.1 ms) to preferentially activate large-diameter afferents, …

Non-Pharmacological Interventions For The Management And Prevention Of Hypertensive Disorders In Pregnancy: A Review Of The Literature, Shenelle K. Smith, Laurena E. Lepp

All Electronic Theses and Dissertations

Hypertensive disorders of pregnancy (HDP), including preeclampsia (PE), are a leading cause of maternal and perinatal morbidity and mortality worldwide. In the United States, rates of HDP continue to rise and are associated with preterm birth, fetal growth restriction, and long-term cardiovascular disease. Current management focuses only on low-dose aspirin for prevention. Surveillance and timely delivery remain the only definitive treatment for preeclampsia. This highlights a critical gap in prevention. Emerging evidence suggests that non-pharmacological interventions–particularly nutrition, physical activity, and lifestyle modification–may reduce the risk and severity of HDP. These approaches align with midwifery models of care emphasizing prevention, education, …

Independent Animal Chiropractic Practice: An Evidence-Based Argument For Autonomy Beyond Veterinary Supervision, Montana Adams

Undergraduate Honors Theses

Animal chiropractic is a growing form of conservative care used to improve mobility, reduce pain, and support neuromusculoskeletal function in animals. Despite evidence suggesting it is both effective and low risk, access remains limited due to inconsistent state regulations. Many jurisdictions require chiropractors to obtain veterinary supervision, referral, or licensure, even when they have completed specialized training and certification in animal chiropractic. This paper evaluates the effectiveness and safety of animal chiropractic while analyzing the impact of current regulatory policies. Research indicates that chiropractic care can improve mobility and reduce spinal conditions in animals when performed by trained professionals. However, …

Dental Implantology: A Literature Review, Kylie Taylor

Undergraduate Honors Theses

Dental implant therapy is the process of replacing teeth as a form of treatment to improve quality of life, function, and esthetics. The success of the implant depends on the surgical technique, type of prosthetic, and factors related to individual patients. The most important factor for implant success is osseointegration. Osseointegration is a process in which success is determined by the bone quality, the surface characteristics of the implant and the surgical approach. Some approaches to improve the osseointegration of the implant are low-speed drilling, guided surgery, and reduced surgical trauma at the site. The impact of systemic conditions, health …

Dose-Dependent Developmental Toxicity Of Cisplatin In Zebrafish Embryos, Reagan D. Sellers, Katherine T. Doucet, Jinhee Park, Andrea Florian

SPARK Symposium Presentations

Cisplatin is a widely used chemotherapy drug for treating various types of cancer. Although cisplatin is effective in killing cancer, it can also cause toxic side effects in normal tissues. Because cisplatin can cross the placental barrier, its use during pregnancy is generally avoided, particularly during early embryonic stages of fetal development. Exposure to cytotoxic drugs during embryogenesis may lead to developmental abnormalities, birth defects, or pregnancy complications. Understanding how cisplatin affects early development is therefore important.          
       Zebrafish (Danio rerio) are an established model for studying developmental toxicity due to their rapid external development, transparent embryos, and genetic similarity to …

Statins For Primary Prevention Of Variceal Bleeding In Cirrhosis: A Scoping Review, Jason Brumitt

Faculty Publications - College of Physical Therapy

Background/Objectives: Variceal bleeding (VB) is a major complication of cirrhosis, marking a progression from a compensated to a decompensated stage of the disease. Previous research has suggested that HMG-CoA reductase inhibitors, commonly called statins, may have therapeutic benefits for those living with cirrhosis, though their exact benefits and role have yet to be elucidated. This scoping review evaluates the potential role of statins in the primary prevention of variceal bleeding in patients with cirrhosis, and if there exists a difference between hydrophilic and lipophilic statins for this indication. Methods: Publications from the last 10 years with primary or secondary outcomes …

Mindfulness Practice And Increases In Gray Matter Density, Gray Matter Volume, And Cortical Thickness: A Scoping Review, Jason Brumitt

Faculty Publications - College of Physical Therapy

Background/Objectives: Mindfulness-based interventions (MBIs) have been linked to psychological and cognitive benefits, yet evidence for their impact on brain structure remains sparse. Neuroimaging suggests MBIs may alter gray matter volume (GMV), density (GMD), and cortical thickness (CT). The purpose of this scoping review was to investigate structural neuroplasticity following MBIs. Methods: Following PRISMA-ScR guidelines, databases were searched for studies published between 2010 and 2023 that used structural MRI to assess structural brain changes in subjects after receiving MBIs. Nine studies met inclusion criteria, including five randomized controlled trials. Results: Mindfulness interventions ranged from 10 h of training to long-term practice …

Temporal Evolution Of Brain Inflammation In The Bilateral Common Carotid Artery Stenosis Model Of Chronic Cerebral Hypoperfusion, Makayla F. Cox, Jill M. Roberts, Ryan K. Shahidehpour, David L. Dornbos Iii, Adam D. Bachstetter

Neuroscience Faculty Publications

Chronic cerebral hypoperfusion is a major contributor to vascular cognitive impairment and dementia, primarily through its disruption of white matter integrity and promotion of neuroinflammatory cascades. The bilateral common carotid artery stenosis (BCAS) model has emerged as the predominant experimental approach for studying the effects of chronic cerebral hypoperfusion, particularly in aging-relevant contexts. This review synthesizes current knowledge of inflammatory responses in the BCAS model, with an emphasis on their temporal progression and functional consequences. We begin by outlining the clinical burden of hypoperfusion, the rationale for BCAS, and the hemodynamic phases it produces. We then examine early neurovascular unit …

Dim Light At Night Impacts Circadian Rhythms And Alzheimer’S Disease-Like Neuroinf Lammation And Neuropathology In Humanized App Saa Knock-In Mice, Marilyn J. Duncan, Margaret R. Hawkins, Leke Bytyqi, Haleigh R. Whitlock, Savannah M. Shepard, Makayla F. Cox, Esther G. Drinkard, Teresa Macheda, Kelly N. Roberts, Katharina Kohler, Mary-Claire Schmidt, Carrie E. Johnson, Sridhar Sunderam, Bruce F. O'Hara, Michael Paul Murphy, Adam D. Bachstetter

Neuroscience Faculty Publications

Artificial light at night (light pollution) is widespread but understudied in the context of Alzheimer’s disease (AD). Sleep and circadian disruption have been linked to amyloid-β (Aβ) accumulation and neuroinflammation, but whether dim light at night (dLAN) modifies these processes remains unclear. We tested whether chronic dLAN exposure (8 lux during the dark phase, 8 weeks) alters circadian rhythms, amyloid pathology, and neuroinflammation in 12–13 month-old humanized APP knock-in (KI) mice. hAPP^SAA KI mice, which develop plaques, were compared with hAPP^WT KI controls carrying only a humanized APP sequence. dLAN reduced circadian rhythm amplitude and stability while increasing …

Brain-Derived Extracellular Vesicles Potentially Mediate Crosstalk With Peripheral Organs In Neurodegenerative Diseases, Ramzi H. Hamdalla, Vibha B. Bhaskar, Changhai Tian

Toxicology and Cancer Biology Faculty Publications

Brain-Derived Extracellular vesicles (BDEVs) are emerging mediators of intra- and interorgan communication in neurodegenerative diseases (NDs) such as Alzheimer’s Disease (AD) and Parkinson’s Disease (PD). A growing body of evidence suggests that BDEVs play an important role in modulating intercellular communication within the central nervous system in the pathogenesis of many NDs. By transporting non-coding RNAs (e.g., miRNAs) and important pathological proteins, BDEVs also influence peripheral organs and contribute to the progression of disease in the central nervous system (CNS). This review extends the understanding of NDs beyond solely brain dysfunction and gives a novel framework for the progression of …

Liposome-Encapsulated Clodronate And Cox-2 Inhibitor Treatment Impair Ventilatory Recovery But Improve Compensatory Locomotor Function Following Cervical Spinal Cord Injury In Rats, Aaron L. Silverstein, Chris M. Calulot, Christopher J. Mclouth, John C. Gensel, Warren J. Alilain

Spinal Cord and Brain Injury Research Center Faculty Publications

Over half of all spinal cord injuries (SCIs) in the United States occur at the cervical level and can cause locomotor deficits and life-threatening breathing dysfunction. Interestingly, the bisphosphonate drug clodronate has shown efficacy in ameliorating tissue damage and improving locomotor recovery acutely after experimentally induced thoracic SCI. Thus, we hypothesized that clodronate treatment would improve recovery of breathing and locomotor function following a C2 hemisection (C2Hx) model of cervical SCI in rats. Serendipitously, changes to animal use guidelines led to the inclusion of carprofen, a non-steroidal anti-inflammatory drug (NSAID), as another independent variable in our study. We treated adult …

Feeding The Family—A Food Is Medicine Intervention: Preliminary Baseline Results Of Clinical Data From Caregivers And Children, Gabriela Drucker, Christa Mayfield, Elizabeth T. Anderson Steeves, Sara Maksi, Tabitha Underwood, Julie Brown, Marissa Frick, Alison Gustafson

Behavioral Science Faculty Publications

Background/Objectives: Food is Medicine (FIM) programs have been shown to be effective at addressing food and nutrition insecurity among individuals. However, more evidence is needed to determine effective interventions at the household level and their impact on child health outcomes. Feeding the Family is a randomized controlled trial which aims to determine whether the amount of food provided and the ability to select foods in FIM interventions have an incremental effect on child and caregiver clinical outcomes relative to nutrition counseling alone. The objective of this paper is to describe the population at baseline among those enrolled in Feeding the …

Pharmacology and Nutritional Sciences Faculty Publications

Organophosphate flame retardants (OPFRs) are used in many consumer products, and their presence in our environment raises concerns about potential health dangers. In humans, exposure to OPFRs, such as tris(1,3-dichloro-2-propyl) phosphate (TDCPP) is associated with metabolic disorders such as obesity, hyperglycemia, and insulin resistance. Our current study seeks to determine how TDCPP exposure affects body composition, glucose homeostasis, and energy balance in a rodent model. C57Bl/6 J mice were divided into two weight-matched groups and fed purified low phytoestrogen diets containing either 0.1 % DMSO (control) or TDCPP 415 mg/kg resulting in an approximate exposure of 50 mg/kg/day. Both male …
