Leveraging Clinical Standards To Improve The Translational Relevance Of Therapies For Experimental Spinal Cord Injury, Aaron L. Silverstein

Theses and Dissertations--Neuroscience

Efforts to improve treatment of spinal cord injury (SCI) often use animals to develop effective therapeutics, intending to improve the survival and the quality of life of persons with SCI. Over half of all SCIs in the United States occur at the cervical level and often cause locomotor deficits and life-threatening breathing dysfunction. Thus, my dissertation is focused on this important patient population.

After beginning with a description of translational research and surveying SCI from a clinical standpoint, I turned to describe experimental models of cervical SCI and more detailed neuroimmunological findings relevant to my work. Then, I conducted a …

Astrocyte Specific Enhancers In The Cortex And Striatum Of Mice, Mikaela Kottelich

Williams Honors College, Honors Research Projects

Among glial cells, astrocytes have a prevalent influence on supporting neuronal function and overall brain health. Specifically targeting this cell type for disease treatment is an existing issue. Other cell types tend to express the desired treatment, which is not always wanted and can lead to unintended, negative consequences. Astrocytes contribute largely to maintaining the blood brain barrier, which is disrupted in Parkinson’s disease. Certain genes are thought to be the reason for this disruption, so if they can be specifically targeted in astrocytes with a specific enhancer, the disruption of the disease could be reversed. In our experiment, we …

Alpha-Synuclein Interaction With Gedunin, Tony Matundura Nyabayo

Graduate Theses/Dissertations

Parkinson’s disease (PD) and other Proteinopathies develop when α-synuclein misfolds and aggregates into toxic amyloids. While existing treatments for PD are primarily focused on managing its symptoms, a viable solution for slowing down the progress of Parkinson’s disease involves targeting the toxic α-synuclein amyloids. Gedunin, a natural inhibitor of heat shock protein 90, has been extensively used to treat malaria. Also, recent research investigations have shed light on its potential beyond malaria therapy, indicating that Gedunin may offer a possible solution for treating a variety of neurodegenerative diseases. Using plate-based assays, we examined how Gedunin influences α-synuclein fibrillation and its …

Effects Of High-Frequency Repetitive Transcranial Magnetic Stimulation On Impulse Control Disorders In Patients With Parkinson’S Disease On Dopamine Replacement Therapy, Katherine Muksuris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Parkinson’s Disease (PD) is a debilitating neurodegenerative disorder that causes motor deficits, cognitive impairment, and depression. The mainstay treatment for motor symptoms is dopamine replacement therapy (DRT). DRT takes the form of levodopa or dopamine receptor agonists (DAs) and can be associated with impulse control disorders (ICDs). Currently, the approach to mitigating these side effects is to decrease or stop DRT, which may cause motor symptoms to return, making the management of the disorder more difficult. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neuromodulation treatment for multiple disorders, including its approved use for smoking cessation. It has also shown …

Review Of The Diagnosis, Pathophysiology, And Treatment Of Naegleria Fowleri-Induced Primary Amoebic Meningoencephalitis, Terrance Zhang

MCB Articles

Naegleria fowleri is a thermophilic, ubiquitous, free-living amoeba, but is also known as the “brain-eating” amoeba. This is the etiological agent of a rare and fulminant waterborne disease known as Primary Amoebic Meningoencephalitis (PAM) that is acutely fatal in 90-99% of reported cases. Those who come into contact with infested waters are at risk of introducing the amoeba into their upper nasal canal, whence the trophozoite form is known to migrate along the olfactory nerve, through the cribriform plate, and enter the central nervous system. Although the exact pathogenesis of N. fowleri is not known, studies have demonstrated contact-dependent and …

Ecological And Pathological Applications Of The Heat Shock Response, Taylor Rae Stanley

Theses and Dissertations

The heat shock response (HSR) is a cytoprotective stress response pathway that regulates cellular proteostasis. The HSR is an evolutionarily conserved pathway that is essential for normal cellular functioning. Here, we explore the broad ecological and pathological impacts of the HSR. In an ecological context, we perform gene level analysis of the transcriptomes of two closely related sunfish. We found that the more invasive bluegill sunfish has gene expansions in two HSR gene families, the HSP70 family and the HSP90 family compared to the redear sunfish. These gene expansions were also observed in several other teleost fish species and were …

This study investigated the effect of Transcutaneous Electrical Nerve Stimulation (TENS) for fibromyalgia-like symptoms including chronic widespread musculoskeletal pain, fatigue, and/or gait impairment in twenty-five individuals with long-COVID. Participants were randomized to a high dose (intervention group, IG) or low dose (placebo group, PG) TENS device. Both groups received daily 3-5 h of TENS therapy for 4-weeks. The Brief Pain Inventory assessed functional interference from pain (BPI-I), and pain severity (BPI-S). The global fatigue index (GFI) assessed functional interference from fatigue. Wearable technology measured gait parameters during three 30-feet consecutive walking tasks. At 4-weeks, the IG exhibited a greater decrease …

Dynamic Dysregulation Of Retrotransposons In Neurodegenerative Diseases At The Single-Cell Level\, Wankun Deng, Citu Citu, Andi Liu, Zhongming Zhao

Faculty, Staff and Student Publications

Retrotransposable elements (RTEs) are common mobile genetic elements comprising ∼42% of the human genome. RTEs play critical roles in gene regulation and function, but how they are specifically involved in complex diseases is largely unknown. Here, we investigate the cellular heterogeneity of RTEs using 12 single-cell transcriptome profiles covering three neurodegenerative diseases, Alzheimer's disease (AD), Parkinson's disease, and multiple sclerosis. We identify cell type marker RTEs in neurons, astrocytes, oligodendrocytes, and oligodendrocyte precursor cells that are related to these diseases. The differential expression analysis reveals the landscape of dysregulated RTE expression, especially L1s, in excitatory neurons of multiple neurodegenerative diseases. …

The Fundamentals Of Antiseizure Medications: A Through Z, Timothy E Welty, Jeannine M Conway, Jacquelyn Bainbridge, Kristen Park, David G Vossler, Archana A Patel, Alica Goldman

Faculty, Staff and Students Publications

Since bromides were first used in 1857 to treat epilepsy, numerous antiseizure medications (ASM) have been developed. Many of these are available for the treatment of epilepsy and status epilepticus today. With so many ASM available, questions arise as to whether all of these medications are needed and when should they be used. As precision medicine begins to play a larger role in determining targeted treatments for specific types of epilepsy, a complete understanding of various medications is needed. Additionally, access to several of these medications can be limited in the United States and are especially limited globally. All these …

Partial Purification Of Alzheimer’S Amyloid-𝛽 Specific Antibody Using Ammonium Sulfate, Noor Yousaf

Undergraduate Research Symposium

Alzheimer's disease (AD) is the most common neurodegenerative disease. The trigger for AD is the accumulation of amyloid-beta protein (Aβ) as senile plaques in the brain. Prior to forming the fiber-like structures found in the plaques, Aβ undergoes an oligomerization process that produces intermediate structures called protofibrils. Substantial data from the Nichols laboratory demonstrated that soluble Aβ protofibrils were highly inflammatory compared to other forms of Aβ. Based on these findings, a serum polyclonal antibody, named Antibody St. Louis or AbSL, was developed to target Aβ protofibrils. A significant challenge with serum antibodies is the presence of many other biological …

Genome-Wide Association Study Meta-Analysis Of Neurofilament Light (Nfl) Levels In Blood Reveals Novel Loci Related To Neurodegeneration, Shahzad Ahmad, Mohammad Aslam Imtiaz, Aniket Mishra, Ruiqi Wang, Marisol Herrera-Rivero, Joshua C Bis, Myriam Fornage, Gennady Roshchupkin, Edith Hofer, Mark Logue, W T Longstreth, Rui Xia, Vincent Bouteloup, Thomas Mosley, Lenore J Launer, Michael Khalil, Jens Kuhle, Robert A Rissman, Genevieve Chene, Carole Dufouil, Luc Djoussé, Michael J Lyons, Kenneth J Mukamal, William S Kremen, Carol E Franz, Reinhold Schmidt, Stephanie Debette, Monique M B Breteler, Klaus Berger, Qiong Yang, Sudha Seshadri, N Ahmad Aziz, Mohsen Ghanbari, M Arfan Ikram

Faculty, Staff and Student Publications

Neurofilament light chain (NfL) levels in circulation have been established as a sensitive biomarker of neuro-axonal damage across a range of neurodegenerative disorders. Elucidation of the genetic architecture of blood NfL levels could provide new insights into molecular mechanisms underlying neurodegenerative disorders. In this meta-analysis of genome-wide association studies (GWAS) of blood NfL levels from eleven cohorts of European ancestry, we identify two genome-wide significant loci at 16p12 (UMOD) and 17q24 (SLC39A11). We observe association of three loci at 1q43 (FMN2), 12q14, and 12q21 with blood NfL levels in the meta-analysis of African-American ancestry. In the trans-ethnic meta-analysis, we identify …

Multimodal Mixing Convolutional Neural Network And Transformer For Alzheimer’S Disease Recognition, Junde Chen, Yun Wang, Adnan Zeb, M. D. Suzauddola, Yuxin Wen

Engineering Faculty Articles and Research

Early recognition of Alzheimer’s disease (AD) and its precursor state, mild cognitive impairment (MCI), is pivotal in interrupting the progression of the disease and providing suitable treatment. Recent development in deep learning techniques has drawn great research attention for improving the efficacy of AD recognition. However, numerous current methods solely utilize data from a single auxiliary domain, limiting their ability to harness valuable intrinsic insights from multiple domains. To cope with the challenge, this paper is devoted to establishing an innovative multimodal medical data fusion model, termed as MMDF, to perform Alzheimer’s disease recognition. Multimodal data including clinical records and …

A Genome-Wide Association Meta-Analysis Of All-Cause And Vascular Dementia, Mega Vascular Cognitive Impairment And Dementia (Megavcid) Consortium

Faculty, Staff and Students Publications

INTRODUCTION: Dementia is a multifactorial disease with Alzheimer's disease (AD) and vascular dementia (VaD) pathologies making the largest contributions. Yet, most genome-wide association studies (GWAS) focus on AD.

METHODS: We conducted a GWAS of all-cause dementia (ACD) and examined the genetic overlap with VaD. Our dataset includes 800,597 individuals, with 46,902 and 8702 cases of ACD and VaD, respectively. Known AD loci for ACD and VaD were replicated. Bioinformatic analyses prioritized genes that are likely functionally relevant and shared with closely related traits and risk factors.

RESULTS: For ACD, novel loci identified were associated with energy transport (SEMA4D), neuronal excitability …

Management Targeted Genetic Evaluation Of An Idiopathic Neuropathy Cohort Through Attrv Amyloidosis Screening, Kristy A. Fisher, Santiago Diaz, Jeffrey Gelblum, Charles Brock, Niraja Suresh, Meghan Towne

HCA Healthcare Journal of Medicine

Background

While the reported prevalence of polyneuropathies is 1%-3%, the incidence of hereditary transthyretin amyloidosis in the United States is estimated to be 1 in 100 000 individuals. Polyneuropathies are known to be difficult to treat and lead to significant morbidity. The aim of pain management is symptomatic treatment, with varying approaches to progression prevention being based on the causative pathophysiology.

We assessed the prevalence of hereditary amyloid transthyretin variant (ATTRv) amyloidosis, a progressive autosomal dominant multisystem disease caused by the abnormal formation and extracellular deposition of transthyretin protein fibrils in various tissues, in an idiopathic polyneuropathy population by using …

Clinical Features And Disease Progression In Older Individuals With Rett Syndrome, Jeffrey L Neul, Timothy A Benke, Eric D Marsh, Bernhard Suter, Cary Fu, Robin C Ryther, Steven A Skinner, David N Lieberman, Timothy Feyma, Arthur Beisang, Peter Heydemann, Sarika U Peters, Amitha Ananth, Alan K Percy

Faculty, Staff and Students Publications

Although long-term survival in Rett syndrome (RTT) has been observed, limited information on older people with RTT exists. We hypothesized that increased longevity in RTT would be associated with genetic variants in MECP2 associated with milder severity, and that clinical features would not be static in older individuals. To address these hypotheses, we compared the distribution of MECP2 variants and clinical severity between younger individuals with Classic RTT (under 30 years old) and older individuals (over 30 years old). Contrary to expectation, enrichment of a severe MECP2 variant (R106W) was observed in the older cohort. Overall severity was not different …

Epidural Stimulation For Urogenital Dysfunction In The Spinal Cord Injured Rat., Natasha Lorraine Wilkins

Electronic Theses and Dissertations

Spinal cord injury (SCI) is a devastating, life changing event that greatly impacts quality of life. SCI can have body-wide, multi-system consequences including dysfunction within the urogenital system. Challenges with the urinary system include urinary incontinence, urine retention, and detrusor-sphincter dyssynergia all of which require maintenance through the regular use of catheters. Sexual dysfunction in men, who comprise nearly 80% of the SCI population, includes erectile dysfunction, anejaculation, retrograde ejaculation, poor expulsive force during ejaculation, and poor sperm quality. The treatment for sexual function in SCI men is focused more on fertility through the collection of sperm for insemination procedures …

In Vivo Examination Of Peripheral Drivers Of Alzheimer’S Disease, Celso Catumbela

Dissertations and Theses (Open Access)

Alzheimer’s disease (AD) is the leading cause of dementia worldwide, and predominantly affects elderly populations. This disease is well known for its effects on the brain, but a wealth of clinical reports show that dementia can also modify, or be modified by, various peripheral and systemic processes. Yet, the pathological contribution of peripheral comorbidities to AD remains to be fully understood. In an attempt to address some knowledge gaps, we characterized the cerebral and peripheral pathology in mice with history of either liver injury or sepsis. In the former subjects, we found that even in the absence of genetic risk …

Self-Harm In Female Youth With Undiagnosed Adhd: Implementing American Academy Of Pediatrics Screening Guidelines, Roselie M. Woodard

Dissertations

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. If undiagnosed or untreated, ADHD can lead to severe psychosocial issues such as academic failure, substance abuse, unplanned pregnancy, and incarceration. The financial burden in the U.S. from diagnostic errors creates an immense, rising fiscal impact. Early diagnosis and management are crucial to prevent these complications.

Females with ADHD, particularly those with the inattentive subtype, often face diagnostic challenges due to symptom masking and over-compensation. This results in poorer cognitive functioning and self-esteem compared to males with ADHD. ADHD is linked to autonomic nervous …

The Evolving Use Of Gold Nanoparticles As A Possible Reversal Agent For The Symptoms Of Neurodegenerative Diseases: A Narrative Review, Alan D. Kaye, Kelly R. Sala, Drew Dethloff, Matthew Norton, Corey Moss, Michael J. Plessala, Alyssa G. Derouen, Yair Lopez Torres, Julian Kim, Sridhar Tirumala, Sahar Shekoohi, Giustino Varrassi

School of Medicine Faculty Publications

Neurodegenerative diseases are broadly hallmarked by impaired energy metabolism and toxic intracellular accumulations such as damaged organelles or reactive oxygen species (ROS). Gold nanoparticles readily cross the blood-brain barrier and increase nicotinamide adenine dinucleotide + hydrogen (NADH) oxidation to nicotinamide adenine dinucleotide (NAD+), which is vital for intracellular energy generation, cellular repair, and protection from ROS. Thus, the use of gold nanoparticles to treat and potentially reverse cellular injury seen in neurodegenerative disease has been an area of ongoing research. This systematic review explores current literature regarding the use of gold nanoparticle therapy in the treatment of neurodegenerative diseases such …

Subpial Resection Of Epileptogenic Tubers: Operative Nuances And Lessons Learned, Nisha Giridharan, Collin W English, Marcus Wong, Howard L Weiner

Faculty, Staff and Students Publications

Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disorder. Tubers of the central nervous system are a hallmark of the disorder and often cause epilepsy. Many TSC patients fail to achieve seizure control with medication alone. Several case series have demonstrated high seizure freedom rates after resective surgery. However, the technique for the resection of epileptogenic tubers has largely been unreported. Here the authors present 2 cases to illustrate their multistage approach for localizing and resecting the seizure onset zone in patients with TSC. At their institution, they have excellent seizure outcomes and a low complication rate with this …

Physical Therapy Faculty Articles and Research

Background

In the United States, there are over seven million stroke survivors, with many facing gait impairments due to foot drop. This restricts their community ambulation and hinders functional independence, leading to several long-term health complications. Despite the best available physical therapy, gait function is incompletely recovered, and this occurs mainly during the acute phase post-stroke. Therapeutic options are limited currently. Novel therapies based on neurobiological principles have the potential to lead to long-term functional improvements. The Brain-Computer Interface (BCI) controlled Functional Electrical Stimulation (FES) system is one such strategy. It is based on Hebbian principles and has shown promise …

Frontotemporal Dementia-Like Disease Progression Elicited By Seeded Aggregation And Spread Of Fus, Sonia Vazquez-Sanchez, Britt Tilkin, Fatima Gasset-Rosa, Sitao Zhang, Diana Piol, Melissa Mcalonis-Downes, Jonathan Artates, Noe Govea-Perez, Yana Verresen, Lin Guo, Don Cleveland, James Shorter, Sandrine Da Cruz

Department of Biochemistry and Molecular Biology Faculty Papers

RNA binding proteins have emerged as central players in the mechanisms of many neurodegenerative diseases. In particular, a proteinopathy of fused in sarcoma (FUS) is present in some instances of familial Amyotrophic lateral sclerosis (ALS) and about 10% of sporadic Frontotemporal lobar degeneration (FTLD). Here we establish that focal injection of sonicated human FUS fibrils into brains of mice in which ALS-linked mutant or wild-type human FUS replaces endogenous mouse FUS is sufficient to induce focal cytoplasmic mislocalization and aggregation of mutant and wild-type FUS which with time spreads to distal regions of the brain. Human FUS fibril-induced FUS aggregation …

Feasibility Of Achieving Nutritional Adequacy In Critically Ill Children With Critical Neurological Illnesses (Cnis)?-A Quaternary Hospital Experience, Marwa Mansour, Nicole Knebusch, Jennifer Daughtry, Thomas P Fogarty, Fong Wilson Lam, Renan A Orellana, Yi-Chen Lai, Jennifer Erklauer, Jorge A Coss-Bu

Faculty, Staff and Students Publications

The literature on the nutritional needs and outcomes of critically ill children is scarce, especially on those with critical neurological illnesses (CNIs). Current evidence shows a lower mortality in patients who achieve two-thirds of their nutritional needs during the first week of pediatric intensive care unit (PICU) admission. We hypothesized that achieving 60% of the recommended dietary intake during the first week of a PICU stay is not feasible in patients with CNI. We designed an observational retrospective cohort study where we included all index admissions to the PICU in our institution of children (1 month to 18 years) with …

Glioblastoma Disrupts Cortical Network Activity At Multiple Spatial And Temporal Scales, Jochen Meyer, Kwanha Yu, Estefania Luna-Figueroa, Benjamin Deneen, Jeffrey Noebels

Faculty, Staff and Students Publications

The emergence of glioblastoma in cortical tissue initiates early and persistent neural hyperexcitability with signs ranging from mild cognitive impairment to convulsive seizures. The influence of peritumoral synaptic density, expansion dynamics, and spatial contours of excess glutamate upon higher order neuronal network modularity is unknown. We combined cellular and widefield imaging of calcium and glutamate fluorescent reporters in two glioblastoma mouse models with distinct synaptic microenvironments and infiltration profiles. Functional metrics of neural ensembles are dysregulated during tumor invasion depending on the stage of malignant progression and tumor cell proximity. Neural activity is differentially modulated during periods of accelerated and …

The Effect Of Repetitive Transcranial Magnetic Stimulation On Brain And Cognitive Variables In Patients With Amnestic Mild Cognitive Impairment, Connor J. Phipps

Theses & Dissertations

Healthy and pathological aging processes can impact human memory. Current interventions for clinical memory impairment offer little opportunity for restoration of memory ability. Fortunately, a novel therapy in the form of repetitive transcranial magnetic stimulation (rTMS) has exhibited promise in this regard. In healthy adults, rTMS of the angular gyrus (AG) has been reported to improve memory. The current study sought to determine the generalizability of these findings to individuals with clinical memory impairment by administering a clinical trial replicating an rTMS protocol reported to improve hippocampal-dependent memory in healthy individuals to individuals with amnestic mild cognitive impairment (aMCI). Individuals …

Rowan-Virtua Research Day

Background: The blood-brain barrier (BBB) is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI). Lipoxins (LXs) are a class of arachidonate-derived eicosanoids, which are a class of specialized pro-resolving lipid mediators (SPMs). SPMs are known to inhibit immune response through inhibition of cellular infiltration, downregulation of pro-inflammatory mediators and upregulation of anti-inflammatory mediators. Hence, LXs are recognized as “breaking signals” in the inflammatory process. One form of LXs, Lipoxin A4 (LXA4) …

The Neuroprotective Role Of Lipoxin A4 In Reinstating Blood Brain Barrier Integrity In Neuroinflammatory Disease Processes, Minjal Patel, Nimish Acharya

Rowan-Virtua Research Day

Background: The blood-brain barrier (BBB), formed by the vascular endothelium, astrocytic foot processes, pericytes, is a highly selective barrier that is responsible for maintaining brain homeostasis and ultimately proper neuronal function. Disruption of the BBB, leading to increased BBB permeability, has been reported in several neurodegenerative diseases, including Alzheimer’s disease (AD) and traumatic brain injury (TBI).¹ Loss of BBB integrity leads to the proliferation of pro-inflammatory cytokines, including TNFɑ, IL-1β, and IL-6.² Moderate inflammation has a beneficial response in the system following an acute injury. However, prolonged inflammation has been known to perturb homeostasis and have …

Pediatric Neurotropic Infection Alters Synaptic Development In The Developing Brain, Anuoluwapo Grace Fadare, Yashika S. Kamte, Manish N. Chandwani, Lauren A. O'Donnell

Rowan-Virtua Research Day

Many neurotropic viruses cause more significant pathology in younger hosts as their brains are still developing. This experiment asked how central nervous system (CNS) viral-infections affect the development of synapses in the pediatric brain during infection and post-infection. Synaptogenesis is at its peak in pediatric mice (10 days old) and we hypothesized that a neurotropic infection could disrupt synaptic proteins. We used a transgenic mouse model where measles virus (MV) infects only mature neurons, leading us to question whether synapses were impacted. We examined synaptic markers in the cerebellum and hippocampus in MV-infected and uninfected mice 9 days and 90 …
