Faculty, Staff and Student Publications

Sigma non-opioid intracellular receptor 1 (Sigma-1R) is an intracellular chaperone protein residing on the endoplasmic reticulum at the mitochondrial-associated membrane (MAM) region. Sigma-1R is abundant in the brain and is involved in several physiological processes as well as in various disease states. The role of Sigma-1R at the blood-brain barrier (BBB) is incompletely characterized. In this study, the effect of Sigma-1R activation was investigated in vitro on rat brain microvascular endothelial cells (RBMVEC), an important component of the blood-brain barrier (BBB), and in vivo on BBB permeability in rats. The Sigma-1R agonist PRE-084 produced a dose-dependent increase in mitochondrial calcium, …

Addressing Stroke Care Disparities Through Patient Education, Christina Annerino

Honors Capstones

It has been found across current studies and evaluations of stroke care and patient outcomes that there is a disparity in disability and mortality between male and female patients who have experienced stroke. The aforementioned studies did not identify the cause of this disparity, although a number of hypotheses for this phenomenon were provided. This study then conducted a preliminary survey of 130 participants, both men and women, aged 18-80 years old, to evaluate potential barriers to accessing stroke care and receiving treatment effectively. Preliminary survey data demonstrated consistent gaps in knowledge related to stroke risks, stroke symptoms, and when …

Introduction Nitrous oxide (N2O), traditionally considered a benign, odorless gas with analgesic and anesthetic properties, has seen a rise in abuse among young individuals in the United States. This abuse can lead to clinically significant neurological symptoms, including peripheral neuropathy and subacute combined degeneration of the spinal cord due to functional B12 deficiency induced by N2O. This case series examines four patients with N20 toxicity, and the functional recovery observed during subsequent follow-up visits after appropriate management. We will explore their motivation for abusing N20, their sources of access, and why its use is on the rise. Cases Description: The …

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 …

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) …

Traumatic Brain Injury (TBI) is a common cause of death and disability in the United States, and it can occur due to varied reasons including motor vehicle accidents, gunshot wounds, and falls. Following TBIs, patients are often left with lifelong disabilities and cognitive problems that can lead to increased risk-taking behaviors. The main goal of my research was to understand the neural mechanisms that drive increased risk-taking behaviors due to TBIs. The specific areas of the brain I was interested in looking at were the medial prefrontal cortex (mPFC), orbitofrontal cortex (OFC), and/or anterior cingulate cortex (ACC) of the prefrontal …

Pituitary Adenoma Presenting As Cranial Nerve Iii Palsy And Hemifacial Pain, Yoona Choe, Justin George, Matthew Boyle, Peter Maduka

Rowan-Virtua Research Day

Pituitary adenomas are common neoplasms arising from the pituitary adenohypophyseal cell. They can be classified by cell type, size and as nonfunctioning or functioning based on the secretion of pituitary hormones. Of these, approximately 48% are macroadenomas (>10 mm) and approximately 53% are prolactinomas. For how common these adenomas are, only 1 of 1100 persons manifest clinical symptoms¹ rendering detection and clinical management challenging.

Non-functioning adenomas are slow growing like most pituitary adenomas and are usually detected due to their mass effect on neighboring structures.² The majority of the reported symptoms as a results of these mass …

Review Of Psychogenic Nonepileptic Seizures And Patient-Centered Approaches To Care, Rabeel Ahmad, Rebekah Dietrich, Munaza Khan

Rowan-Virtua Research Day

Psychogenic nonepileptic seizures (PNES) are defined as involuntary experiential and behavioral responses to internal or external stimuli. They are behaviors, not associated with pathological alterations in the physiology of the brain. Although some of them mimic syncope, they have historically been regarded to clinically resemble epileptic episodes.

There is a multiplicity of different names for this condition. PNES is the most widely used term, though the term "functional seizures" is increasingly used. Alternatives such as "psychogenic seizures," "dissociative seizures," "psychogenic nonepileptic attacks" (PNEA), and "nonepileptic seizures" are also used.

Rowan-Virtua Research Day

Parkinson’s Disease (PD) is a prevalent and devastating neurodegenerative disorder that causes progressively worsening motor symptoms affecting locomotor and oropharyngeal function. There is limited research in animal models on swallowing dysfunction in PD. To examine how neurodegeneration in PD produces progressive impairment in the oropharyngeal and locomotor processes, rotenone, a type II mitochondrial inhibitor, was injected into Lewis rat models to reproduce a parkinsonian phenotype. We hypothesized that the animal models injected with the rotenone will exhibit both oropharyngeal dysfunction and locomotor deficiency with an increased deficit that correlates with prolonged treatment. We utilized 18 rats receiving either 2.75 mg/kg …
