Tumor–Immune Dynamics With Memory And Time Delay: A Fractional-Order Model With Ctla-4 Regulation, Mutaz Mohammad, Mohyeedden Sweidan, Alexander Trounev, Fathalla Rihan

Mathematical Modelling and Numerical Simulation with Applications

This study develops a fractional-order tumor-immune interaction model incorporating Caputo memory effects, delayed immune activation, and CTLA-4 checkpoint regulation. The model describes the coupled dynamics of tumor cells, CD4$^{+}$ T cells, IFN-$\gamma$, and CTLA-4, and extends classical integer-order tumor-immune models by accounting for hereditary immune responses and biologically motivated latency effects. Theoretical properties, including positivity, boundedness, equilibrium structure, and fractional-order stability, are examined to establish the biological and mathematical consistency of the model. The delayed fractional system is then investigated computationally by comparing several numerical methods, including finite difference discretization, Daubechies wavelet collocation, Euler wavelet collocation, and a predictor-corrector scheme. …

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 …

Sexually Dimorphic Effects Of Gpnmb Modulation On Vertebral Bone Mass Regulation And Intravertebral Disc Health, Hakem Altawil, Fayez Safadi

Williams Honors College, Honors Research Projects

Osteoporosis and vertebral degeneration are major contributors to musculoskeletal morbidity, yet the molecular mechanisms regulating vertebral bone and intervertebral disc (IVD) homeostasis remain incompletely understood. GPNMB (osteoactivin) has been identified as a regulator of bone remodeling, though its role in spine health is unclear. This study evaluated the effects of GPNMB deficiency on lumbar vertebral bone microarchitecture and IVD integrity in a sex-dependent context.

Six-month-old male and female wild-type (WT) and GPNMB knockout (KO) mice were analyzed using micro–computed tomography (µCT) of lumbar vertebrae (L4–L6) and histological assessment of the L5–L6 IVD. KO males exhibited increased bone volume fraction, bone …

Oropharyngeal Syphilis Presenting As Tongue Based Ulcer With Lymphadenopathy, Serena F. Pu, Kevin J. Carlson, Jonathan R. Mark, Benjamin J. Rubinstein

Department of Otolaryngology (ENT) Faculty Publications

Within the aerodigestive tract, syphilis presents with varied signs and symptoms, some of which may mimic malignancy or other disease processes. We present the case of a 29-year-old man with otalgia and odynophagia who was found on physical examination and office laryngoscopy to have a 4-cm ulcerative mass of the tongue base and cervical lymphadenopathy. While planning for tissue diagnosis, the patient’s serologies revealed positive treponemal antibody testing and elevated rapid plasma reagin (RPR) titers, confirming syphilitic infection, likely representing secondary syphilis. While awaiting operative biopsy, the patient received intramuscular penicillin with complete resolution of the mass and symptoms, and …

Paneugenesis: A Regenerative Systems Hypothesis For Advancing Health Promotion, Craig M. Becker, Leslie Hoglund, Beth Chaney, Joseph G. L. Lee, Michael Stellefson, Alex Davis

Epidemiology, Biostatistics, & Environmental Health Faculty Publications

Despite major advances in health promotion science, dominant approaches remain largely prevention-and risk-reduction-oriented. The prevailing orientation creates a substantial opportunity to advance generative, system-design strategies that intentionally produce well-being rather than merely prevent disease. This article proposes paneugenesis as a regenerative systems framework and a testable theoretical model for the intentional creation of net-positive outcomes, thereby extending health promotion beyond its traditional pathogenic emphasis. Paneugenesis integrates systems science, salutogenesis, behavioral science, complexity theory, and quality management principles into a unified four-function process: operationalizing idealized outcomes, identifying key precursors, optimizing processes, and continually plotting progress through feedback mechanisms. The central hypothesis …

Identification And Preclinical Assessment Of Novel Therapeutic Modalities In Environmental Exposure-Induced Lung Disease, Aaron D. Schwab

Theses & Dissertations

Environmental lung diseases are preventable respiratory conditions either caused or made worse by inhaled environmental exposures. Contemporarily, environmental lung diseases are most associated with workplace exposures given specific occupational processes aerosolize inflammatory agents that can be inhaled at high concentrations. Although a considerable amount is known regarding immunoglobulin (Ig)E-mediated responses to environmental exposures, little is known about non-IgE mediated respiratory conditions resulting from lipopolysaccharide (LPS)-enriched organic dust exposure(s). Chronic respiratory diseases such as asthma, hypersensitivity pneumonitis, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis have all been identified as environmental lung diseases caused or exacerbated by such environmental dusts. Therapeutic …

Effects Of Social Isolation On Cecum Opioid Receptor Expression And Affective Behavior, Jordan Riser, John Tkaczynski, Nicole Shellenbarger, Maya Patel, Daniel Chandler, Daniel Manvich

Rowan-Virtua Research Day

BACKGROUND

Psychological stress can induce gastrointestinal symptoms and exacerbate existing gastrointestinal disorders, indicating an interaction between the central and enteric nervous systems. Central nervous system activation of opioid receptors stimulates sympathetic outflow to the enteric nervous system, delaying motility and reducing gastrointestinal secretions, producing a similar clinical presentation to IBS.

HYPOTHESIS

We hypothesize that social isolation induces anxiety states, disrupting homeostatic noradrenergic activity in the brain and gut, leading to neurophysiological changes in the cecum characterized by altered expression of opioid receptors.

METHODS

Sprague-Dawley rats were housed in either group (control) or socially isolated conditions. Affective behavior was assessed using …

Advancing Research On Retinitis Pigmentosa: An Investigation Of Natural History, Visual System Plasticity, And Mutation-Independent Treatment., Cecilia A. Attaway

Electronic Theses and Dissertations

Retinitis Pigmentosa (RP) is an inherited retinal disease characterized by rod and then cone photoreceptor degeneration. ~25% of cases are caused by a genetic mutation that results in autosomal dominant RP (adRP). There has been a lack of exploration of the progression of degeneration in adRP models. In Chapter Two, I examined visual acuity (VA) changes, retinal structure, and function from early to late-stage disease in a murine P23H Rho ‘knock-in’ mouse model (Rho^P23H/+), the most common form of adRP in North America. To establish a natural history, I evaluated behavioral VA, using the visual water task, …

Effects Of Social Isolation On Locus Coeruleus Opioid Receptor Expression And Affective Behavior, John Tkaczynski, Jordan Riser, Maya Patel, Nicole Shellenbarger, Jin Park, Daniel Manvich, Daniel J Chandler

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Social isolation is a stressor that impairs homeostatic neuroendocrine functions and is associated with the development of several mood disorders characterized by persistent negative affect. Persistent feelings of loneliness have been growing public health concerns for several years and were greatly exacerbated by the onset of the COVID-19 pandemic. The problem has grown so severe the U.S. Surgeon General recently declared loneliness to be an epidemic health concern that is associated with poor mental and somatic health outcomes. Therefore, identifying mechanisms of neuroadaptation that contribute to the development of persistent negative affect is a critical step in the identifying better …

Determining Essential Regulatory Factors In Extravillous-Trophoblast Differentiation And Splice Variants Associated With The Development Of Preeclampsia, Brandt Hugh Beck

Electronic Theses & Dissertations (2024 - present)

Preeclampsia is a common condition affecting mothers across the world. Rates for preeclampsia have been rising in the past years due to factors such as obesity and diabetes. Since this condition has been more prevalent, a better understanding of the factors surrounding the preeclamptic state are needed. Core cell types and biological functions of placenta development are known but the cause behind the preeclamptic environment is not well understood. This research aims to investigate the potential causes behind preeclampsia by first reviewing Extravillous-Trophoblast differentiation factors in the context of differential gene expression and alternative splicing then evaluate towards preeclamptic tissue. …

Understanding The Role Of Mastl In Colon Homeostasis And Colitis-Associated Cancer Development, Kristina Pravoverov

Theses & Dissertations

Colitis-associated cancer (CAC) is the most devastating complication of longstanding inflammatory bowel disease (IBD). Understanding the mechanisms underlying the switch from damage-repair to dysplasia in IBD is critical for identifying novel therapies to facilitate mucosal healing while mitigating CAC risk. Microtubule-associated serine-threonine kinase-like (MASTL), though crucial in cell growth and repair, is upregulated in sporadic colorectal cancer and CAC. This study sought to delineate the role of MASTL in colitis and CAC development.

First, we examined whether MASTL is associated with colitis and recovery. Review of publicly available data found significant elevation of MASTL and interleukin (IL)-22 in biopsies from …

Unraveling The Role Of Gjb3 In Lung Adenocarcinoma, Swathi M. Priyanka

Theses & Dissertations

Lung cancer stands as a leading cause of cancer-related mortality worldwide, with small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC) comprising its primary categories. NSCLC, representing nearly 85% of cases, exhibits a 5-year survival rate of less than 21%. Among NSCLC subtypes, lung adenocarcinoma (LUAD) prevails as the most common, followed by squamous cell carcinoma and large cell carcinoma. Gap junctions are crucial for intercellular communication and cellular homeostasis maintenance, demonstrate altered expression patterns in various diseases, including cancer. Gap junction beta 3 (GJB3 or Connexin31) exhibits significant expression in both preclinical and clinical LUAD samples, prompting investigation into …

Interactions Between Repetitive Mild Traumatic Brain Injury And Methylphenidate Administration On Catecholamine Transporter Protein Levels Within The Rodent Prefrontal Cortex, Anna Abrimian, Eleni Papadopoulos, Christopher P. Knapp, J. Loweth, Barry Waterhouse, Rachel Navarra

Rowan-Virtua Research Day

It is theorized that low concentrations of dopamine (DA) and norepinephrine (NE) within in the prefrontal cortex (PFC) following traumatic brain injury (TBI) leads to increased risky behavior. Our lab has shown that repeated mild TBI (rmTBI) sex-differentially increases risky behavior in a rodent model. Methylphenidate (MPH) is a psychostimulant drug used to treat symptoms of Attention-Deficit Hyperactivity Disorder (ADHD), also driven by a hypo-catecholaminergic PFC. MPH elevates catecholamine levels by blocking DA and NE transporters, DAT and NET. While the potential of psychostimulants to treat post-TBI symptoms have been explored, the effects of sub-chronic MPH on transporter levels following …

Fos Expression In Lateral Hypothalamus/Perifornical Area Is Correlated With Psychosocial Stress-Induced Cocaine-Seeking Behavior In A Sex-Specific Manner, Milena Sudarikov, Nicole M. Hinds, Ireneusz D. Wojtas, Desta M. Pulley, Daniel F. Manvich

Rowan-Virtua Research Day

Cocaine Use Disorder persists as a significant public health concern in the United States. Recent epidemiological data indicate that rates of cocaine-involved overdose deaths are rising, and treatment of Cocaine Use Disorder is challenging due to a lack of FDA-approved medications to help patients achieve abstinence and avoid relapse. Stress can precipitate cocaine craving and trigger relapse episodes, however the underlying neural circuitry by which stressors drive cocaine seeking is not completely understood. Our laboratory has recently identified the potential involvement of the rostrolateral aspect of the periaqueductal gray (rlPAG) in psychosocial stress-induced cocaine-seeking behavior using a rodent model of …

A Preliminary Report On The Role Of Lipoxin A4 In Reinstating The Blood-Brain Barrier Integrity In A Rodent Model Of Acute Inflammation With Impaired Cerebrovasculature, Minjal Patel, Shruti Varshney, Ananya Nethikunta, George G. Godsey, Mary C. Kosciuk, Ana Rodriguez, Bernd Spur, Kingsley Yin, Randel L. Swanson, Venkat Venkataraman, Robert G. Nagele, Nimish Acharya

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) …

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 …

Intra-Accumbens Microinfusion Of The Dopamine D3 Receptor Partial Agonist (±)Vk4-40 Does Not Affect Basal Locomotion In Mice, Yeonwoo Sim, Nicole M. Hinds, Amy Hauck Newman, Daniel F. Manvich

Rowan-Virtua Research Day

The opioid epidemic remains a pressing public health crisis, prompting the search for alternative pharmacotherapies for Opioid Use Disorder (OUD). This study explores the potential of the dopamine D3 receptor (D3R) partial agonist, (±)VK4-40, as a novel treatment option. We investigated the impact of intra-nucleus accumbens (NAc) microinfusion of VK4-40 on basal locomotion in mice. Results indicate that VK4-40 did not significantly alter basal locomotion, suggesting that its therapeutic effects may not be mediated through disruptions in generalized motor function. Future research will focus on elucidating the neuropharmacological mechanisms underlying VK4-40's therapeutic actions and exploring its effects on psychostimulant-induced hyperlocomotion. …

Fused In Sarcoma Regulates Glutamate Signaling And Oxidative Stress Response, Chiong-Hee Wong, Abu Rahat, Howard C Chang

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Mutations in fused in sarcoma (fust-1) are linked to ALS. However, how these ALS causative mutations alter physiological processes and lead to the onset of ALS remains largely unknown. By obtaining humanized fust-1 ALS mutations via CRISPR-CAS9, we generated a C. elegans ALS model. Homozygous fust-1 ALS mutant and fust-1 deletion animals are viable in C. elegans. This allows us to better characterize the molecular mechanisms of fust-1-dependent responses. We found FUST-1 plays a role in regulating superoxide dismutase, glutamate signaling, and oxidative stress. FUST-1 suppresses SOD-1 and VGLUT/EAT-4 in the nervous system. FUST-1 also regulates synaptic AMPA-type glutamate receptor …

Inhibiting Pi3k/Akt To Enhance Brain Uptake Of Anticancer Agents In Glioblastoma, Louis Rodgers

Theses and Dissertations--Pharmacy

Glioblastoma (GBM) is the deadliest and most common malignant CNS tumor. Despite advances in understanding its biology and the development of targeted therapies, effective treatment options remain limited. As a result, patient survival rates are dismal, with a 5-year survival rate of only 6.8% and an overall survival of less than two years. This poor outcome is partly due to our inability to treat GBM cells that infiltrate the whole brain. Focal treatments like surgery and radiotherapy alone are insufficient due to these invasive tumor cells. Therefore, chemotherapy following resection and irradiation of the primary tumor is essential to eliminate …

Employing A Machine Learning Approach In Precision Oncology To Predict Pik3ca Functional Status And Identify Phenocopying Variants Of Deleterious Pik3ca Mutations, Javier Castillo

CMC Senior Theses

The following proposal describes a modular machine learning approach that detects malfunctioning genes and pathways in cancer using the transcriptome of cancer patients. The transcriptome is underused in precision oncology and, combined with machine learning, can aid in the identification of hidden responders. Applied to the PI3K/AKT/mTOR pathway, this method can be used to predict PIK3CA functional status and identify phenocopying variants of deleterious PIK3CA mutations. The classifier will do this by integrating RNA-seq, copy number, and mutation data from tumors to determine the functional status of PIK3CA using a set of learned gene-specific weights. The classifier will then be …

Autonomic Modulation Of Cardiac Function In Hypertrophic Cardiomyopathy, Jenna Rose Disser

Dissertations, Master's Theses and Master's Reports

Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disorder. HCM is characterized by cardiac hypertrophy, fibrosis, and an increased risk of fatal arrhythmias and sudden cardiac death. Previous studies in humans with HCM have demonstrated increased cardiac norepinephrine spillover and reduced beta-1 receptor (β1R) expression in the left ventricle (LV). We have previously demonstrated that cardiac sympathetic tone is elevated in an alpha-tropomyosin mutant mouse model of HCM. We hypothesized that HCM mice would demonstrate reduced β1R expression in the LV and attenuated heart rate (HR) and dP/dt max responses to ramped infusion of the β1R agonist, dobutamine. …

Air-Jet Bioprinting Of Stem Cell-Encapsulated Alginate Micro-Droplets For Organoid Biomanufacturing, Mirabella B. Stump

Electronic Theses and Dissertations

Biomanufactured 3D-organoids show promise for modeling and treating various conditions, particularly insulin-dependent diabetes mellitus (type-1 diabetes). Pancreatic islet organoids serve as sustainable sources of insulin-producing β-cells, potentially restoring insulin regulation in patients and providing a long-term solution for diabetes. Hydrogel droplet printing is an emerging technique in regenerative medicine due to its advantageous tunability and biocompatibility; however, challenges of consistency, quality control, and scalability persist. To address these issues, we developed a novel air-jetting based droplet bioprinting system for the generation of monodispersed alginate micro-droplets. The objective of this project was to incorporate human induced pluripotent stem cells (hiPSCs) into …

Ethanol Dysregulates Sirt1-Mediated Lipogenic Signaling Pathways Through Α4*-Nicotinic Acetylcholine Receptors In Hepatocytes., Caitlin Christina Wilkerson

Electronic Theses and Dissertations

Alcohol-associated liver disease (ALD) is a broad spectrum of diseases ranging from steatosis to severe hepatic cirrhosis, none of which have any FDA approved therapies. Downregulation of hepatic Sirtuin 1 (Sirt1) activity by ethanol has been shown to lead to an upregulation of the pro-lipogenic gene targets under its jurisdiction, resulting in increased lipogenesis and triglyceride accumulation. It was hypothesized that ethanol acts on α4*-nicotinic acetylcholine receptors (α4*-nAChRs) in hepatocytes to decrease Sirt1 expression, which ultimately dysregulates lipid metabolic homeostasis. Ethanol’s effects were investigated in cultured AML12 hepatocytes and in WT primary mouse hepatocytes acutely exposed to ethanol. Consistent with …

Investigating The Effects Of Subchronic Dietary Zinc Supplementation On Diet-Induced Metabolic Dysfunction-Associated Steatotic Liver Disease., Oluwanifemi Esther Bolatimi

Electronic Theses and Dissertations

Zinc deficiency is associated with metabolic dysfunction-associated steatotic liver disease (MASLD). Previous studies show zinc supplementation improves steatosis, but its therapeutic effects in established MASLD remain unclear. We developed a model to characterize the effects of zinc supplementation on high-fat diet (HFD) induced MASLD and hypothesized established MASLD would be attenuated. Mice were fed control diet or HFD for 12 weeks and then grouped into normal or zinc-supplemented diets for 8 additional weeks. At euthanasia, plasma and liver tissues were collected for phenotypic analysis. Twelve weeks of HFD altered glucose clearance and body composition. Eight weeks of subsequent zinc supplementation …

Invited Review: Adrenocortical Function In Avian And Non-Avian Reptiles: Insights From Dispersed Adrenocortical Cells., Rocco V. Carsia, Patrick J. Mcilroy, Henry B John-Alder

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Herein we review our work involving dispersed adrenocortical cells from several lizard species: the Eastern Fence Lizard (Sceloporus undulatus), Yarrow's Spiny Lizard (Sceloporus jarrovii), Striped Plateau Lizard (Sceloporus virgatus) and the Yucatán Banded Gecko (Coleonyx elegans). Early work demonstrated changes in steroidogenic function of adrenocortical cells derived from adult S. undulatus associated with seasonal interactions with sex. However, new information suggests that both sexes operate within the same steroidogenic budget over season. The observed sex effect was further explored in orchiectomized and ovariectomized lizards, some supported with exogenous testosterone. Overall, a suppressive effect of testosterone was evident, especially in cells …

Role Of Chronic Stress-Induced Neuroinflammation In Rodent Locus Coeruleus Physiology And Anxiety-Like Behaviors, Arthur Anthony Alfonso Reyes

Graduate School of Biomedical Sciences Theses and Dissertations

The locus coeruleus (LC), the primary site of brain norepinephrine (NE), is a key anatomical brain region implicated in the stress response. Stress is a neuroendocrine physiologic response to a stressor that promotes organism survival through adaptive change and restoration of homeostasis. The central stress response, which drives behavioral and physiological change, is primarily mediated by activating the hypothalamic-pituitary-adrenal (HPA) axis. While advantageous in the short term, chronic stress exposure can lead to HPA axis and LC dysregulation, which are thought to contribute to the etiology of anxiety disorders. Previous studies demonstrate the effects of acute stress in increasing LC …

Facial Analytics Based On A Coordinate Extrapolation System (Zface) For Morphometric Phenotyping Of Developing Zebrafish, Lorena Maili, Oscar E Ruiz, Philip H Kahan, Frankie Chiu, Stephen T Larson, S Shahrukh Hashmi, Jacqueline T Hecht, George T Eisenhoffer

Faculty, Staff and Student Publications

Facial development requires a complex and coordinated series of cellular events that, when perturbed, can lead to structural birth defects. A quantitative approach to quickly assess morphological changes could address how genetic or environmental inputs lead to differences in facial shape and promote malformations. Here, we report on a method to rapidly analyze craniofacial development in zebrafish embryos using facial analytics based on a coordinate extrapolation system, termed zFACE. Confocal images capture facial structures and morphometric data are quantified based on anatomical landmarks present during development. The quantitative morphometric data can detect phenotypic variation and inform on changes in facial …

Differential Degeneration Of Neurons In A Mouse Model Of Canavan Disease, Vibha Chauhan, Quy Nguyen, Jeremy Francis, Paola Leone

Rowan-Virtua Research Day

Canavan disease (CD) is an inherited leukodystrophy caused by inactivating mutations to the glial enzyme aspartoacylase (ASPA). ASPA catabolizes neuronal N-acetylaspartate (NAA) into free acetate and aspartate and loss of this function results in the chronic elevation of non-catabolized NAA and the failure of developmental myelination. Elevated NAA is thought to cause damage to myelin and myelin-producing cells (oligodendrocytes, but the viability of neurons in CD is relatively unexplored. We compare here the progressive degeneration of neurons in two regions of the CD mouse brain, the thalamus and the cortex, distinguished by differing degrees of vacuolation, and show that the …

Maackia Amurensis Seed Lectin (Masl) Increases Movement Velocity Of Mice With Tnfα Induced Rheumatoid Arthritis, Amanda A. Greenspan, Kelly L. Hamilton, Alan J. Shienbaum, Bradford Fischer, Andrea Bottaro, Gary S. Goldberg

Rowan-Virtua Research Day

Up to 70 million people around the world suffer from rheumatoid arthritis. Current treatment options have varied efficacy and can cause unwanted side effects. New approaches are needed to treat this condition. Sialic acid modifications on chondrocyte receptors have been associated with arthritic inflammation and joint destruction. The transmembrane mucin receptor protein podoplanin (PDPN) has been identified as a functionally relevant receptor that presents extracellular sialic acid motifs. PDPN signaling promotes inflammation and invasion associated with arthritis and, therefore, has emerged as a target that can be used to inhibit arthritic inflammation. Maackia amurensis seed lectin (MASL) can target PDPN …

The Role Of Food Accessibility In Weight Loss In A Rat Model Of Parkinson’S Disease, Anjali Kikkisetti, Nicole Charles, Francois Gould

Rowan-Virtua Research Day

Parkinson’s disease (PD) is a neurodegenerative disorder that causes a variety of motor and non-motor symptoms. The goal of this project was to understand whether the weight loss seen with Parkinson’s disease was due to the lack of being able to access the food because of the food placement or because of inability to chew the food due to degeneration of muscles required for chewing food. Both treatment groups, Adjusted Diet and Unadjusted Diet, lost weight after injections started, whereas control weights were stable throughout the experiment. There is no statistically significant difference in weight loss between adjusted and unadjusted …
