BACKGROUND: Podoplanin (PDPN) has emerged as a functionally relevant biomarker and chemotherapeutic target expressed by OSCC cells. PDPN signaling can directly increase tumor cell invasion and metastasis, and also inhibit host lymphocyte activation and immune response. Accordingly, antibodies and Maackia amurensis seed lectin (MASL) can target the PDPN receptor to inhibit OSCC cell migration and viability. However, the effects of MASL on OSCC cells in oral cancer patients has not yet been reported.

METHODS: We conducted a Phase 1 human clinical trial to examine the effects of a single 100 mg oral dose of MASL on OSCC cell morphology, PDPN …

A Review Of Sutures And The Prospective Applications Of Nanofiber Technology In Suture Engineering, Hanna Brancaccio, Dominique Hassinger, Vincent Beachley

Rowan-Virtua Research Day

Introduction: Suturing is a method to close surgical or traumatic wounds to promote healing. The ideal suture should have high tensile strength that loses strength at the same rate as the healing tissue gains strength, be easy to handle and form secure knots, induce minimal inflammation, and stretch/recoil according to wound contraction. While there are suture materials available for use in various procedures that fulfill most requirements, no one suture possesses every desirable characteristic, and limitations are still prevalent. Nanofiber geometry has a well-known ability to modulate cell morphology, attachment, gene expression, extracellular matrix production, and macrophage polarization in …

Hypoxia Induced Ribosomal Rna Fragmentation Mediated By Rnase L, Vanessa Kristina Pizutelli, Dimitri G Pestov

Rowan-Virtua Research Day

Ischemic injury contributes to a range of global pathologies. Ischemia/Reperfusion Injury (IRI) is a paradoxical phenomenon that involves an initial restriction of blood flow followed by a sudden restoration of perfusion. This type of injury takes place in conditions such as myocardial infarction, acute kidney disease, and ischemic stroke and often leads to cellular death. Additionally, IRI exacerbates post-surgical outcomes and plays a role in graft dysfunction and transplant rejection. Despite efforts to develop therapies targeting known IRI pathways, clinical trials have largely been unsuccessful, underscoring the need for alternative mechanisms and biomarkers associated with IRI-induced apoptosis. Reactive oxygen species …

Longitudinal Changes In Aerodigestive Responses To Varying Nipple Properties In Infant Pigs, François D H Gould, Christopher Mayerl, Khaled Adjerid, Jessica Reibel, Nichole Charles, Chloe Edmonds, Rebecca Z German

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Coordination of respiration and swallowing is critical for survival in infant mammals and changes throughout infant maturation. Infants show sensorimotor feeding responses to changes in physical properties of nipples. Commercial nipples are promoted as improving aerodigestive coordination. However, it is unknown how nipple properties influence coordination of respiration and swallowing. Furthermore, how infant-nipple interactions change throughout maturation is not well understood. We designed and manufactured four silicone nipples of the same shape that varied in two parameters: nipple opening diameter and nipple stiffness. We used our validated infant pig model to test the impact of nipple parameters on aerodigestive coordination …

Sk609, A Novel Dopamine D3 Receptor Agonist And Norepinephrine Transporter Blocker With Putative Pro-Cognitive Actions, Does Not Induce Psychostimulant-Like Increases In Risky Choice During Probabilistic Discounting, Christopher P. Knapp, Brooke Fallon, Sandhya Kortagere, Barry D. Waterhouse, Stan B Floresco, Rachel L Navarra

Rowan-Virtua School of Osteopathic Medicine Departmental Research

RATIONALE: Psychostimulants, such as amphetamine (AMPH) and methylphenidate (MPH), non-selectively elevate extracellular concentrations of the catecholamine neurotransmitters, dopamine (DA) and norepinephrine (NE), and are common pharmacological strategies used to improve prefrontal cortex (PFC)-dependent cognitive dysfunction. However, this approach can be problematic given AMPH has been shown to increase preference for risky choices in a rodent assay of risk/reward decision making. SK609 is a novel NE reuptake blocker that selectively activates DA D3 receptors without affinity for the DA transporter. SK609 has been shown to improve cognitive performance without increasing psychostimulant-like spontaneous locomotor activity, suggesting SK609 may benefit neurocognitive function without …

Emerin Deficiency Drives Mcf7 Cells To An Invasive Phenotype, Emily Hansen, Christal Rolling, Matthew Wang, James M Holaska

Rowan-Virtua School of Osteopathic Medicine Departmental Research

During metastasis, cancer cells traverse the vasculature by squeezing through very small gaps in the endothelium. Thus, nuclei in metastatic cancer cells must become more malleable to move through these gaps. Our lab showed invasive breast cancer cells have 50% less emerin protein resulting in smaller, misshapen nuclei, and higher metastasis rates than non-cancerous controls. Thus, emerin deficiency was predicted to cause increased nuclear compliance, cell migration, and metastasis. We tested this hypothesis by downregulating emerin in noninvasive MCF7 cells and found emerin knockdown causes smaller, dysmorphic nuclei, resulting in increased impeded cell migration. Emerin reduction in invasive breast cancer …

In Search Of The Locus Coeruleus: Guidelines For Identifying Anatomical Boundaries And Electrophysiological Properties Of The Blue Spot In Mice, Fish, Finches, And Beyond, Amelien Vreven, Gary Aston-Jones, Anthony E Pickering, Gina R Poe, Barry Waterhouse, Nelson K Totah

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Our understanding of human brain function can be greatly aided by studying analogous brain structures in other organisms. One brain structure with neurochemical and anatomical homology throughout vertebrate species is the locus coeruleus (LC), a small collection of norepinephrine (NE)-containing neurons in the brainstem that project throughout the central nervous system. The LC is involved in nearly every aspect of brain function, including arousal and learning, which has been extensively examined in rats and nonhuman primates using single-unit recordings. Recent work has expanded into putative LC single-unit electrophysiological recordings in a nonmodel species, the zebra finch. Given the importance of …

The use of deep learning to evaluate CT angiograms for intracranial aneurysms has been sparsely studied. This literature review aims to determine the accuracy and reliability of deep learning to analyze CT angiograms in patients suspected to have intracranial aneurysms.

METHODS

A qualitative review of literature using PubMed, SCOPUS, and EMBASE was conducted. Inclusion criteria comprised articles …

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 …

Purpose: To compare the pullout strength of a bio-inductive implant (BI) used to augment a medial patellofemoral ligament (MPFL) repair with the pullout strength of semitendinosus graft in a biomechanical cadaveric model. Methods: Six matched pairs of cadavers (12 knees) were used in the biomechanical testing comparing semitendinosus tendon (Semi-T) versus a BI. The Semi-T was harvested from 1 of the matched pairs. A standard double-bundle technique using 2 sockets in the upper two-thirds of the patella 15 mm apart was performed. After docking of the graft into the patella, the patella was dissected free of soft tissues and potted …

Implementation Barriers Of Multidisciplinary Care In Chronic Kidney Disease Through A Cfir Framework: A Narrative Review, Max J. Goodman, Amalia Jereczek

Cooper Rowan Medical Journal

Introduction: 37 million Americans suffer from chronic kidney disease, which affects multiple organ systems and requires multidisciplinary care. Multidisciplinary care is an inherently broad and complex topic, and while it is being implemented across healthcare in the United States and abroad, multidisciplinary care outcomes are poor in this patient population. It is possible that there exists gaps in the literature regarding implementation and replication of multidisciplinary care interventions such that healthcare practices are unable to fully take advantage of multidisciplinary care publications for chronic kidney disease. This narrative review utilizes the five domains of the Consolidated Framework for Implementation Research …

Awareness & Prevention Of Health Hazards For Americans Embarking In Space Tourism, Krzysztof Zembrzuski

Rowan-Virtua Research Day

Since the beginning of spaceflight, keeping humans healthy has been a serious concern. Prior to 2021, astronauts had to undergo an elite selection process to embark in space travel. Now that commercial spaceflight is a reality, the criteria to experience space has been significantly loosened, raising health concerns to a larger and unhealthier pool of travelers. Most commercial spaceflight clients are anticipated to be middle-aged adults, which implies many will suffer from high blood pressure and heart disease, both of which are frequent ailments in this age group. Because of the massive compression the body undergoes during takeoff and return, …

Extravasated Brain-Reactive Autoantibodies Perturb Neuronal Surface Protein Expression In Alzheimer's Pathology, Wardah Bajwa, Mary Kosciuk, Randel L. Swanson, Anuradha Krishnan, Venkat Venkataraman, Robert Nagele, Nimish Acharya

Rowan-Virtua Research Day

Background: Increased blood-brain barrier (BBB) permeability is reported in both the neuropathological and in vivo studies in both Alzheimer’s Disease (AD) and age matched cognitively normal, no cognitive impairment (NCI), subjects. Impaired BBB allows various vascular components such as immunoglobulin G (IgG) to extravasate into the brain and specifically bind to various neuronal surface proteins (NSP), also known as brain reactive autoantibodies (BrABs). This interaction is predicted to further enhance deposition of amyloid plaques.

Hypothesis: Interaction between extravasated BrABs and its cognate NSPs lower the expression of that NSPs in AD patients.

Methods: We selected Western blotting technique to study …

Blood-Tissue Barriers And Autoantibodies In Neurodegenerative Disease Pathogenesis: An Approach To Diagnostics And Disease Mechanism, Eric Luria Goldwaser

Graduate School of Biomedical Sciences Theses and Dissertations

Brain homeostasis can be affected in a number of ways that lead to gross anatomical, cellular, and molecular disturbances giving rise to diseases like Alzheimer’s disease (AD) and related dementias. Unfortunately, the mechanistic pathoetiology of AD’s hallmark features of cerebral amyloid plaque buildup and neuronal death are still disputed. Using human brain AD sections, immunohistochemistry experiments revealed internalized surface proteins, co-localized to an expanded lysosomal compartment. Other stains for amyloid-β1-42 (Aβ42) and various immunoglobulin (Ig) species displayed them leaking out of the cerebrovasculature through a dysfunctional blood-brain barrier (BBB), binding to neurons in the vicinity, and localizing to intracellular vesicles …

Herpes simplex virus type 1 (HSV-1) has the ability to enter many different hosts and cell types by several strategies. This highly prevalent alphaherpesvirus can enter target cells using different receptors and different pathways: fusion at a neutral pH, low-pH-dependent and low-pH-independent endocytosis. Several cell receptors for viral entry have been described, but several observations suggest that more receptors for HSV-1 might exist. In this work, we propose a novel role for the proteolipid protein (PLP) in HSV-1 entry into the human oligodendrocytic cell line HOG. Cells transfected with PLP-EGFP showed an increase in susceptibility to HSV-1. Furthermore, the infection …

The study of extracellular vesicles (EVs) in cancer progression is a complex and rapidly evolving field. Whole categories of cellular interactions in cancer which were originally presumed to be due solely to soluble secreted molecules have now evolved to include membrane-enclosed extracellular vesicles (EVs), which include both exosomes and shed microvesicles (MVs), and can contain many of the same molecules as those secreted in soluble form but many different molecules as well. EVs released by cancer cells can transfer mRNA, miRNA, and proteins to different recipient cells within the tumor microenvironment, in both an autocrine and paracrine manner, causing a …
