The Rpm-1/Phr Signaling Hub Modulates Tau-Induced Neurodegeneration Through Regulation Of Microtubule Stability And Mapk Pathways In C. Elegans, Xinxing Ding

Theses and Dissertations

Neurodegenerative diseases, including Alzheimer's disease and frontotemporal dementia, are characterized by the accumulation of pathological tau proteins and progressive neuronal loss. Although research regarding tau-mediated toxicity is extensive, the specific pathology that determine whether neurons maintain homeostasis or succumb to collapse under tau-induced stress remain incompletely elucidated. A central, yet still insufficiently understood, feature of these diseases is the disruption of the microtubule (MT) cytoskeleton . The PHR protein family is evolutionarily highly conserved; within this family, RPM-1 in C. elegans functions as an intracellular signaling hub that regulates axon development, synapse formation, axon termination, and various microtubule-associated processes. This …

Persistent Chemotherapy-Induced Peripheral Neuropathy As A Chronic Cancer Pain Syndrome: Mechanisms, Therapeutic Limitations, And Future Directions, Reed Firestone, Jamin Morrison

Department of Medicine Faculty Papers

Background/Objectives: Chemotherapy-induced peripheral neuropathy (CIPN) is a common, dose-limiting complication of cancer therapy and a major contributor to chronic neuropathic pain among cancer survivors. Although traditionally managed as a treatment-related toxicity, persistent CIPN frequently persists long after chemotherapy completion and is increasingly recognized as a major survivorship and palliative care challenge. This review synthesizes current mechanistic, clinical, and translational evidence and reframes persistent CIPN as a chronic neuropathic cancer pain syndrome. Methods: A narrative review of peer-reviewed literature was conducted using PubMed/MEDLINE, Embase, and the Cochrane Library, supplemented by manual review of key references and clinical guidelines. Emphasis was placed …

Spontaneous Intracranial Hypotension With Negative Brain Mri Findings: A Systematic Review Of Diagnostic Strategies And Clinical Outcomes, Marina Romozzi, Giuseppe Garignano, Valid Rastegar, Francesco Onorati, Catello Vollono, Federico Tosto, Masahito Katsuki, Yasuhiko Matsumori, Francesco Signorelli

Student Papers, Posters & Projects

BACKGROUND: Spontaneous intracranial hypotension (SIH) is a debilitating syndrome typically characterized by orthostatic headache and classic brain MRI findings. However, brain MRI abnormalities are indirect manifestations of cerebrospinal fluid (CSF) volume depletion rather than direct evidence of the leak, and some patients may present with unrevealing or absent typical brain MRI findings, posing a considerable diagnostic challenge.

METHODS: A comprehensive search of PubMed/Medline, Web of Science, and Scopus was conducted to perform a systematic review, according to PRISMA guidelines, analyzing the available evidence on MRI-negative SIH (patients without typical SIH findings on their initial brain MRI), including its clinical features, …

The Neuroprotective Effect Of Cdc42 Inhibition In The G93a Mutant Hsod1 Mouse Model Of Als, Andrea Koly

Undergraduate Theses, Capstones, and Recitals

Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disease characterized by the selective loss of upper and lower motor neurons, leading to muscle weakness, neuromuscular junction (NMJ) degeneration, paralysis, and eventual death due to respiratory failure. Despite extensive research, effective disease-modifying therapies remain limited, underscoring the need to identify novel molecular targets involved in ALS pathogenesis. Dysregulation of Rho family GTPases has been implicated in neurodegeneration, with Rac and Rho exerting opposing effects on neuronal survival; however, the role of the closely related GTPase Cdc42 remains poorly understood in ALS. In this study, the therapeutic potential of inhibiting …

Seeing The Pattern: Optic Neuritis, Multifocal Mri Lesions, And The Early Diagnosis Of Multiple Sclerosis, Jose J. Loayza Pintado, William Reckley, Aura Calderon, Luis Gaitan

Research Symposium

Background: Optic neuritis is a common neuro-ophthalmic emergency and may be the first clinical manifestation of inflammatory demyelinating disease. In the acute setting, clinicians must rapidly distinguish multiple sclerosis (MS) from important mimics, particularly when optic nerve involvement is accompanied by spinal cord lesions. A structured approach integrating phenotype, MRI lesion distribution and activity, and cerebrospinal fluid (CSF) markers can support timely diagnosis and guide counseling regarding long-term management. We report a young man presenting with unilateral optic neuritis and prior transient neurologic episodes, highlighting a practical diagnostic framework applicable to emergency and inpatient care.

Case Presentation: A 27-year-old man …

Mapping The Neuroexposome: Integrative Analysis Of Dementia Risk Factors Through Multi-Omics And Environmental Profiling In The Egyptian Population., Mai Ahmed Saadzaghloul Othman

Theses and Dissertations

Background: Dementia represents one of the most pressing public health challenges of the twenty-first century, with the global burden projected to reach 153 million cases by 2050. Egypt, as the most populous Arab nation, faces a corresponding rise in age-related diseases, yet comprehensive data from low- and middle-income countries remain severely limited. The neuroexposome framework, integrating genetic susceptibility, environmental exposures, and metabolic alterations, offers a powerful strategy to characterize the complex interplay between internal and external risk factors for Alzheimer's disease (AD) and Alzheimer's disease Related Dementias (ADRD).

Objectives: This thesis aimed to: (1) examine the distribution of APOE alleles …

From Combustion Emissions To Neurotoxicity: Brain Health Risks Of Military Burn Pits Exposure, Katherine M. Eggers, Zoe A. Keller, Paul Barach, Julie M. Tomáška, Joshua P. Nixon, Janeen H. Trembley, Tammy A. Butterick

College of Population Health Faculty Papers

Military burn pits used during post-9/11 U.S. military deployments functioned as uncontrolled combustion systems and were widely utilized to dispose of large volumes of outdoor waste by burning. Burn pits involved heterogeneous waste materials burned under variable temperature and oxygen conditions. These combustion environments generated complex, toxic, multipollutant airborne emission mixtures that included particulate matter (PM2.5), polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs). This narrative review synthesizes epidemiologic, experimental, and mechanistic evidence linking burn pit emissions to disruption of the lung–brain axis and adverse neurological outcomes. We specifically aim to address a critical gap in understanding how combustion-derived …

Fentanyl Mediated Distortions Of Phasic Dopamine Release Dynamics Encoding Natural Reward And Aversive Processing In The Mammalian Mesolimbic Circuit, Oliver P. Culver Iv

MUSC Theses and Dissertations

Mu opioid receptor (MOR) agonists are recognized to disinhibit tonic dopamine (DA) in the ventral striatum (VS), contributing to opioid addiction and euphoria. However, MOR agonists can also inhibit non-drug reward-seeking, and disrupt conditioned responding to aversive stimuli, a phenomenon not readily explained by tonic DA disinhibition. We hypothesized that this effect could be due in part to disruption of phasic DA responses to conditioned stimuli (CS) which critically shape and maintain behaviors during naturalistic reward and aversive processing. Because MOR effects on CS-evoked phasic DA are largely unexamined, we conducted in vivo fiber photometric recordings in water-deprived male and …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …

Parkinson’S Disease Phenotype Stratification Using Multiple Correspondence Analysis, Kelly Astudillo

Dissertations, Theses, and Capstone Projects

Parkinson’s disease (PD) is the second most common neurodegenerative disorder, with over 12 million people projected to be affected by 2040 (Dorsey et al., 2018). Deep phenotyping and stratification can provide useful information regarding PD pathogenesis and can aid in the  development of disease modifying therapies that aim to delay the progression or prevent the onset of neurodegeneration (Blandini et al., 2019; Smith & Schapira, 2022). Utilizing multivariate methods such as multiple correspondence analysis (MCA) permits for the simultaneous analysis of distinct data modalities. To the best of our knowledge, MCA has not been previously used to explore phenotype patterns …

Fda Approval Of Tradipitant: A Novel Approach To Motion Sickness Treatment, Haley Brown, Jennifer Cao, Allie Honigford, Leah Heitkamp, Sarah Hiett, Connor Dains, Brenna Hissong, Manoranjan D'Souza

Pharmacy and Wellness Review

Motion sickness is a prevalent neurophysiological condition affecting approximately one-third of the worldwide population, resulting from sensory mismatch and the brain’s internal model of motion. It is characterized by nausea, vomiting, dizziness, and autonomic symptoms during exposure to actual or virtual motion, which may significantly impair daily functioning and quality of life. Current guidelines recommend the prevention and treatment of motion sickness through pharmacologic, herbal, and non-pharmacologic strategies. Scopolamine and first-generation antihistamines are effective pharmacologic options, while ginger has demonstrated some benefit in reducing symptoms as an herbal option. Non-pharmacologic interventions such as habituation training, behavioral techniques, and sensory strategies …

Lovastatin Potentiates The Function Of Α7-Nicotinic Acetylcholine Receptors, Dmytro Isaev, Keun-Hang Susan Yang, Murat Oz

Pharmacy Faculty Articles and Research

Background/Objectives: Statins are currently one of the most commonly used cholesterol-lowering drugs. In recent years, in addition to their well-known effects on the cardiovascular system, statins have been shown to exert beneficial effects in the progression of various neuropsychiatric and neurodegenerative diseases. Methods: In this study, the effects of lovastatin on the function of α7-nicotinic acetylcholine (nACh) receptors expressed in rat hippocampus and Xenopus oocytes were investigated. Results: In whole-cell patch clamp studies in hippocampal neurons, 21-day chronic (20 mg/kg), but not acute (20 min), lovastatin treatment caused significant potentiation of choline (a selective agonist for α7 nACh receptors)-induced currents …

Objective Oculomotor, Vestibular, Reaction Time, And Cognitive Signatures Of Vestibular Migraine, Claire E. J. Ceriani, Alexandr Braverman, Alexander Kiderman

Department of Neurology Faculty Papers

OBJECTIVE: To evaluate oculomotor, vestibular, reaction time, and cognitive (OVRT-C) function in patients with vestibular migraine (VM) using objective eye-tracking-based metrics and to identify patterns of dysfunction relative to healthy controls.

BACKGROUND: Vestibular migraine is a common yet underdiagnosed cause of vertigo. Diagnosis remains primarily clinical, because objective neurologic and vestibular findings are often absent or inconsistent. Quantitative methods capable of capturing the multisystem manifestations of VM may improve objective characterization of the disorder.

METHODS: Participants with a clinical diagnosis of vestibular migraine were recruited from a tertiary headache center and assessed using a battery of OVRT-C tests administered with …

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 …

Quantifying Black Carbon Concentrations in Georgia and Analyzing Associated Public Health Risks

One of the most daunting challenges of the industrial world is air pollution. Within this broad spectrum, there is an inhalable particle group named PM2.5, which contains black carbon. Black carbon has evidence that supports the generation and worsening of adverse health impacts, which may include birth complications, cognitive deficits in children, pulmonary aggravation, asthma, cardiovascular issues, neurological degenerative patterns, and cancer risk. This is especially seen in vulnerable populations, like children, elderly, and those who already suffer from weakened health, many of which reside in the southern …

Head Acceleration Events in Collegiate Rodeo Athletes

Colton Carlson, MS4

Mentor: Thayne Munce, PhD

Introduction: Brain health has been a growing concern across a wide range of contact sports in the last three decades. While most of the early brain health research was focused on identifying and preventing concussions, newer research has found that an accumulation of repetitive head impacts (RHI) is more predictive of long-term brain health than the number of concussions sustained. Consequently, being able to assess RHI in sports despite the lack of outward symptoms has become paramount in promoting the long-term health of athletes. While the …

Objective: To establish a baseline profile of spatial learning and memory across age and genotype in rate model.

Methods: The Morris Water Maze (MWM) was used to assess four groups of rats: young Wild Type (WT), young APP/PS1 (AD), middle-aged WT, and middle-aged AD. Spatial learning was evaluated during acquisition (Day 1–4) using cumulative proximity and escape latency. Memory was assessed using probe trials (Day 2–4). Swim velocity …

Incidence Of Stroke Post Pulmonary Thrombectomy: Implications For Periprocedural Management, Rohan Umrani, Rameez Shahid, Luai Tabaza

Rowan-Virtua Research Day

Background: The incidence of stroke after pulmonary thrombectomy (PT) remains unknown. Given the incidence of patent foramen ovale (PFO) of 25% in autopsy studies, the concern for paradoxical embolus in this patient population warrants evaluation of periprocedural management.

Methods: We queried the EPIC EHR at Virtua Health in New Jersey for all patients who underwent PT from 2021-2025, categorized by utilization of the Inari Flowtriever system or the Penumbra thrombectomy device. We assessed post-PT cerebrovascular accident (CVA), PFO presence by transthoracic echocardiogram (TTE), and gender via descriptive statistics. Age, average anesthesia time and procedure supply cost were assessed via two-sided …

Effect Of Parkinson’S Disease On The Lateralization Of The Digastric Muscle In A Rodent Model, Estelle Richardson, Francois Gould

Rowan-Virtua Research Day

In Parkinson’s disease, the loss of dopaminergic neurons in the substantia nigra can cause dysphagia, which affects all phases of swallowing. In swallowing, bilateral pairs of muscles under the control of independent unilateral neural mechanisms must simultaneously activate to coordinate their movements and produce a swallow. However it is unknown how Parkinson’s disease impairs the activation of the right and left sides of those muscles. In this study we tested how Parkinson’s disease impacts the lateralization of the digastric muscle in rats. We hypothesized that Parkinson’s disease will cause a difference in activation of the right and left digastric muscles …
