Spontaneous Intracranial Hemorrhage In A 29-Year-Old Male: A Case Report, Md Fateha, Caroline Nguyen, Michael A. Morris

Rowan-Virtua Research Day

Spontaneous intracranial hemorrhage is rare, especially in a young patient population. Signs and symptoms of intracranial hemorrhage include facial droop, vision loss, motor deficits with extraocular movements, deficits with tongue movement, weakness in the arms or legs, sensation loss, and mental status change. This is a case report of a 29-year-old male with no past medical history who presented for a spontaneous intracranial hemorrhage. This patient's only neurologic deficit was the loss of visual field on the left inferior quadrant of his field of vision. The patient obtained a CT head non-contrast which showed 21 mm acute right occipital hemorrhage …

‘Not So Atypical’: An Atypical Presentation Of West Nile Virus And Guillain-Barre Syndrome, Matthew Orap, Sana Tahir, Ugonna Ononuju, Naresh Kumar

Rowan-Virtua Research Day

Guillain-Barre Syndrome (GBS) is defined by acute areflexic paralysis, usually starting in the distal lower extremities, and ascending to the upper extremities. It is associated with albuminocytologic dissociation, which involves elevated protein levels and normal cell counts in the cerebrospinal fluid. One of the types of GBS, called Miller-Fischer Syndrome (MFS), is characterized by ophthalmoplegia, ataxia, and areflexia. This case report focuses on a 49-year-old male with an atypical presentation of Guillain-Barre syndrome. Guillain-Barre syndrome can be classically caused by Campylobacter jejuni. However, there can be other infectious causes as well, namely Cytomegalovirus, Epstein-Barr virus, Varicella-Zoster virus, …

Rowan-Virtua Research Day

Meningoencephalitis is a broad range of symptoms as a sequela of inflammation of the CNS system. It is a diagnosis that is often missed, especially in atypical presentations. We describe a case of HSV encephalitis that presented to the ER afebrile with atypical arm movements, most similar to a monochorea, and discuss other cases in the literature of atypical presentations of this disease.

Evaluating C-Reactive Protein Associated Risk Of Cardiovascular Disease In Patients With Autism Spectrum Disorder, Brandon Cunha, Andrea Iannuzzelli, Rohan Mehra

Rowan-Virtua Research Day

This study examines the relationship between C-reactive protein (CRP) levels and cardiovascular disease (CVD) risk in 293 patients with Autism Spectrum Disorder (ASD) from the Rowan-Virtua Regional Integrated Special Needs Center (RISN Center). Baseline CRP values were gathered from EMR and evaluated for CVD risk. ASD patients have increased prevalence of CVD risk factors, and the literature demonstrates a strong relationship between CRP and CVD risk in this population. Patients were stratified by severity of ASD to investigate potential differences. Severe limitations in EMR data and overall sample size limited the generalizability and significance of this study. Larger scale studies …

Transcranial Electrical Stimulation As A Treatment For Aging-Related Cognitive Disorders: Review Of Published Evidence, Srujan Dadi, Kyle Jackson, Don Shamilov

Rowan-Virtua Research Day

Alzheimer's disease (AD) and MCI are a major concern in modern neuropsychiatric care, chiefly for their difficult management. This strategic literature review categorizes MCI via the Jak-Bondi criteria and relates it to tES treatment paradigms. Commonly used outcome measures and regional brain mapping data synergizes associations between MCI pathology and potential tES treatment targets. Effect sizes were calculated and attributed to outcome measures based on primary articles evaluating the efficacy of tES. These were then corresponded to a desired Jack-Bondi classification. A better understanding of the efficacy of tES on specific brain regions in synergy with diagnostic criteria will allow …

Isolation Of Aged Mouse Primary Microglia As A Model System For Alzheimer’S Disease Research, Michael Landis

Biology Honors Papers

Microglia and their role as the immune cells of the central nervous system are an emerging area of interest within Alzheimer’s research, particularly as they have shown in a benevolent and malevolent cellular context. Models of Alzheimer’s disease are very light in studying microglia, so in this study a model of microglia isolated from aged mice is established in order to study the phagocytic activity and protein expression of microglia in response to Amyloid Beta. The cells were isolated from aged mice and cultured before being used to confirm cellular identity, as well as to measure phagocytic activity. This study …

Exploring The Neuroprotective Effects Of Cannabinoids On Oxygen Glucose Deprived Neurons In An In-Vitro Model Of Stroke, Bhavya Chatragadda, Emily Potts, Hang Ma, Navindra Seeram, Claudia Fallini

Senior Honors Projects

Stroke is a leading cause of long-term disability and decreased mobility worldwide. During stroke, neuronal damage results from both the initial oxygen-glucose deprivation and the increase in excitotoxicity and oxidative stress after restoration of blood flow, a phase called Ischemia-Reperfusion Injury (IRI). Reducing the impact of these processes could result in better outcomes for post-stroke patients by preventing excessive neuronal death. Many natural compounds derived from the Cannabis Sativa plant have been tested for neuroprotective effects due to their potential antioxidant properties. We hypothesized that neurons treated with cannabinoids immediately after experiencing an acute ischemic event will have an overall …

The Pam-1 Aminopeptidase Protects Against Neurodegeneration In Caenorhabditis Elegans, Caleb Coil

Honors College Theses

The deteriorating effects of neurodegenerative conditions seem inescapable for many as they age. The experimental exploration of the molecular and cellular mechanisms responsible for neurodegeneration is aided using animal models. For instance, genetic screens have identified the puromycin-sensitive aminopeptidase (PSA) as a novel effector of neurodegeneration, as mutations in PSA in fruit flies result in perturbations of neuron anatomy and an accelerated onset of neuron death. We have tested the hypothesis that PAM-1, the Caenorhabditis elegans ortholog of PSA, plays a similar role in governing neurodegeneration in nematodes. Genetic strains were created that express the green fluorescent protein (GFP) in …

Retinoid X Receptor As A Mediator Of Post Stroke Recovery By Reversing Age-Associated Phenotypes Of Microglia/Macrophages, Shun-Ming Ting

Dissertations and Theses (Open Access)

After stroke, microglia (MG) and blood-derived macrophages, together (MF), clear dead cells and cellular debris in the infarcted brain through phagocytosis. However, the phagocytic capability of MF declines with age. Age-related changes in MF phenotype also include overactive inflammatory responses to stroke-induced brain injury, altogether resulting in poor recovery after stroke. Retinoid-X-receptor (RXR) is a pleiotropic transcription factor. Our studies suggest that RXRa enhances MF phagocytic functions, reduces inflammatory responses, and improves post-stroke recovery. To establish phenotypes of aging MF, MG were MACS-sorted from the brains of young adults (2-4 months old) and aged (18-20 months old) mice for transcriptomic …

Locally Injectable Peptide Hydrogel For Conversion Of Temozolomide And Codelivery Of Sirna In Glioblastoma Multiforme Treatment, Megan Pitz

All Dissertations

Traditional treatment methods for glioblastoma multiforme (GBM) are largely unsuccessful, with a 5-year survival rate of 5.6%. Temozolomide (TMZ), the only chemotherapy FDA-approved for GBM treatment, is a hydrophobic prodrug that is stable in an acidic pH and begins converting to its active form at a physiological pH of 7.4. However, complete conversion of TMZ is observed only at a higher pH, and only about 30% of administered TMZ reaches the central nervous system. Therefore, there is a need for new treatment methods that maximize TMZ delivery to and efficacy at the tumor site. Self-assembling peptides are a unique class …

After reviewing the titles, abstracts and protocols of each study, 13 articles were extracted for detailed assessment. The main indicators in the study included clinical signs of gingival inflammation, bleeding on probing (BoP), bone loss (BL), periodontal probing depth (PPD), and clinical attachment loss (CAL). Additionally, levels …

Sequence Learning In A 6-Ohda Mouse Model Of Parkinson’S Disease, Ani Gribbin

Neuroscience Honors Projects

Parkinson’s disease (PD), a neurodegenerative disorder originating in the dopaminergic cells of the basal ganglia, is characterized by severe motor impairments such as tremors, bradykinesia, and postural instability. However, non-motor symptoms impacting sensory systems and cognition are consistently pointed to as more greatly affecting quality of life for PD patients. Cognitive impairments in PD can include changes in reward processing, depression, apathy, and increases in risk-taking behavior. Additionally, learning and memory deficits are seen in PD, specifically in motor sequence learning. Often, the neural correlates of sequence learning impairments are traced to the substantia nigra. However, there is some evidence …

Home-Based Virtual Culinary Nutrition Education Sessions For Amyotrophic Lateral Sclerosis Patients: Quantitative Experimental Pilot Study, Ciara N. Reistad, Mauricio Lobo

Department of Nutrition Student Projects

Amyotrophic lateral sclerosis (ALS) impairs voluntary muscular activity and often results in malnutrition. The need for specialized dietary therapy for ALS-related illnesses is highlighted by recent research, but it also draws attention to the lack of targeted care and ongoing nutritional status monitoring. Technological developments like telehealth and chatbots hold potential for ALS patients’ nutritional monitoring. The pilot study examined the feasibility and impact of home-based virtual culinary nutrition education sessions on nutritional knowledge, dietary intake of energy (CHO), protein (PRO) and FAT, body mass index (BMI), and functional status assessed by ALSFRS-R scores in patients with Amyotrophic Lateral Sclerosis …

Hippocampus Diffusivity Abnormalities In Classical Trigeminal Neuralgia, Shaun Andrew Hanycz, Alborz Noorani, Peter Shih-Ping Hung, Matthew R. Walker, Ashley B. Zhang, Timur H. Latypov, Mojgan Hodaie

Student Papers, Posters & Projects

INTRODUCTION: Patients with chronic pain frequently report cognitive symptoms that affect memory and attention, which are functions attributed to the hippocampus. Trigeminal neuralgia (TN) is a chronic neuropathic pain disorder characterized by paroxysmal attacks of unilateral orofacial pain. Given the stereotypical nature of TN pain and lack of negative symptoms including sensory loss, TN provides a unique model to investigate the hippocampal implications of chronic pain. Recent evidence demonstrated that TN is associated with macrostructural hippocampal abnormalities indicated by reduced subfield volumes; however, there is a paucity in our understanding of hippocampal microstructural abnormalities associated with TN.

OBJECTIVES: To explore …

Apigenin Alleviates Autistic-Like Stereotyped Repetitive Behaviors And Mitigates Brain Oxidative Stress In Mice, Petrilla Jayaprakash, Dmytro Isaev, Keun-Hang Susan Yang, Rami Beiram, Murat Oz, Bassem Sadek

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Studying the involvement of nicotinic acetylcholine receptors (nAChRs), specifically α7-nAChRs, in neuropsychiatric brain disorders such as autism spectrum disorder (ASD) has gained a growing interest. The flavonoid apigenin (APG) has been confirmed in its pharmacological action as a positive allosteric modulator of α7-nAChRs. However, there is no research describing the pharmacological potential of APG in ASD. The aim of this study was to evaluate the effects of the subchronic systemic treatment of APG (10–30 mg/kg) on ASD-like repetitive and compulsive-like behaviors and oxidative stress status in the hippocampus and cerebellum in BTBR mice, utilizing the reference drug aripiprazole (ARP, 1 …

Multiple sclerosis is the most common autoimmune disease affecting the central nervous system (CNS) worldwide. Multiple sclerosis involves inflammatory demyelination of nerve fibers in the CNS, often presenting with recurrent episodes of focal sensory or motor deficits associated with the region of the CNS affected. The prevalence of this disease has increased rapidly over the last decade. Despite the approval of many new pharmaceutical therapies in the past 20 years, there remains a growing need for alternative therapies to manage the course of this disease. Treatments are separated into two main categories: management of acute flare versus long-term prevention of …

Dysexecutive Difficulty And Subtle Everyday Functional Disabilities: The Digital Trail Making Test, David J Libon, Rod Swenson, Sean Tobyne, Ali Jannati, Daniel Schulman, Catherine C Price, Melissa Lamar, Alvaro Pascual-Leone

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Digital neuropsychological tests reliably capture real-time, process-based behavior that traditional paper/pencil tests cannot detect, enabling earlier detection of neurodegenerative illness. We assessed relations between informant-based subtle and mild functional decline and process-based features extracted from the digital Trail Making Test-Part B (dTMT-B).

METHODS: A total of 321 community-dwelling participants (56.0% female) were assessed with the Functional Activities Questionnaire (FAQ) and the dTMT-B. Three FAQ groups were constructed: FAQ = 0 (unimpaired); FAQ = 1-4 (subtle impairment); FAQ = 5-8 (mild impairment).

Results: Compared to the FAQ-unimpaired group, other groups required longer pauses inside target circles (p < 0.050) and produced more total pen strokes to complete the test (p < 0.016). FAQ-subtle participants required more time to complete the entire test (p …
