Fungal Foes And Fatty Defenses: How Simulated Snake Skin Lipids Influence Ophidiomyces Ophiodiicola Growth, Thalia Rodriguez, Jacey Cardenas, Lizbeth Delarosa, Krupa Patel, John Niedzwiecki

Science University Research Symposium (SURS)

Emerging fungal diseases are a continuous threat to wildlife health as well as biodiversity. Fungal diseases, such as white nose syndrome in bats, can devastate populations by disrupting their ecosystems. Many other species around the world are affected by fungal diseases, such as amphibians, birds, and snakes. In more recent years, snake fungal disease (SFD) emerged due to the fungal pathogen Ophidiomyces ophiodiicola (O.o). Like Pseudogymnoascus destructans, the fungal pathogen responsible for white nose syndrome, O.o targets the skin which contains many fatty acids. Some studies have shown that fatty acids present in bat skin are able to inhibit fungal …

Crossroads Of Covid-19 And Alzheimer’S: Investigating Sars-Cov-2 Nsp6 And Orf7a In Amyloid-Β42 Toxicity, Jeffrey William Huettemann, Amit Singh

Research from the Berry Summer Thesis Institute, 2025

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) resulted in several hundred million contracted cases of coronavirus disease 2019 (COVID-19) and a global pandemic. In some of these cases, previous neurological diseases, such as Alzheimer’s disease (AD), seemed to progress much more rapidly after the COVID-19 infection. Thus, we became interested in studying the effects of SARS-CoV-2 infection on prior neurological disease progressions.

To modulate this condition, we used Drosophila melanogaster as a genetic model system. We had previously developed the Alzheimer’s Disease Fly Model with expression of human amyloid beta 42 (Aβ42) peptide, which is responsible for extracellular Aβ-42 …

Alfred Russel Wallace Notes 37. What About Wallace On Vaccination . . . ?, Charles H. Smith

Faculty/Staff Personal Papers

Best known for his natural history studies on evolution and biogeography, Alfred Russel Wallace (1823−1913) had a significant second career as a social critic. One of his most controversial stances was his position on (smallpox) vaccination. Anti-vaxxers of the present frequently bring up his name as a resource for their side, but the situation is not so easily reducible to that.

Investigating Regulation Of Neutrophil-Mediated Inflammation In Mycoplasma Pneumoniae Infection, Nathan D. Velazquez

University Scholar Projects

No vaccine exists for Mycoplasma pneumoniae (Mp) infections, largely due to the

gap in understanding in the virulence and immunopathogenesis of this bacterium.

We have recently demonstrated that neutrophils are maladaptive in the context of

Mp infection, and drive disease severity while also impairing bacterial clearance.

Furthermore, we observed that B cells play a regulatory role in limiting disease

severity by modulating neutrophilic inflammation. We investigated this

phenomenon further to elucidate the mechanisms by which B cells regulate

neutrophilic inflammation. We utilized a monoclonal antibody to deplete B cells

during Mp infection and found that B-cell-depleted mice had elevated neutrophil …

BACKGROUND: Same-day testing and treatment of curable sexually transmitted infections (STI) is a strategy to reduce infection duration and onward transmission. South African primary healthcare facilities often lack sufficient waiting spaces. This study aimed to assess the proportion of, and factors influencing, pregnant women waiting for on-site STI test results before and after the installation of clinic-based waiting rooms. METHODS: We conducted an observational quality improvement study at 5 public primary healthcare facilities in South Africa from March 2021 to May 2023. The intervention was the installation of a waiting room in two clinics. Three clinics were used as comparators: …

Clinical Characteristics And Outcomes Of Pediatric Staphylococcal Scalded Skin Syndrome (Ssss) At An Inner-City Tertiary Care Center, Nina Kb Gust Md, Ashley Frei Bs, Rebecca M. Adams Bs, Elika Ridelman Phd, Christina Shanti Md, Ronald Thomas Phd, Jocelyn Y. Ang Md

Medical Student Research Symposium

Introduction

Staphylococcal Scalded Skin Syndrome (SSSS) is a blistering skin condition caused by a toxin-producing staphylococcus species. Epidemiologic studies on pediatric SSSS in the United States are limited, with a reported incidence of 7.67 cases per million children and 45.1 per million infants. Immature renal function, lack of protective antibodies, and increased exotoxin target desmoglein-1 are hypothesized to increase incidence in younger children. We aimed to determine clinical and microbiological characteristics of pediatric SSSS and factors that could help predict disease severity.

Methods

A retrospective chart review was performed for admitted patients under 18 years old diagnosed with SSSS from …

The soluble variant of the ectopeptidase CD13 (sCD13), released from the cell surface by matrix metalloproteinase 14 (MMP14), is a potent pro-inflammatory mediator, displaying chemotactic, angiogenic, and arthritogenic properties through bradykinin receptor B1 (B1R). We revealed a link between sCD13 and amplified neutrophil-mediated inflammatory responses in SARS-CoV-2 infection. sCD13 was markedly elevated in patients with COVID-19 and correlated with disease severity and variants, ethnicity, inflammation markers, and neutrophil extracellular trap formation (NETosis). Neutrophils treated with sCD13 showed heightened NETosis and chemotaxis, which were inhibited by sCD13 receptor blockade. Meanwhile sCD13 did not induce platelet aggregation. Single-cell analysis of COVID-19 lungs …

Mage-A4 Induces Non-Small Cell Lung Cancer And Tumor-Promoting Plasma Cell Accumulation, Dominique Armstrong, Cheng-Yen Chang, Monica J Hong, Linda Green, Yichao Shen, William Hudson, Kelsey E Mauk, Li-Zhen Song, Sheetal Jammi, Benjamin Casal, Brianna Burns, Chad J Creighton, Alexandre Carisey, Xiang H-F Zhang, Neil J Mckenna, Sung Wook Kang, Hyun-Sung Lee, William Decker, David B Corry, Farrah Kheradmand

Adaptive immunity is critical in eliminating tumors, but cancer-intrinsic factors can subvert this function. Melanoma antigen-A4 (MAGE-A4), a cancer-testis antigen, is expressed in solid tumors and correlates with poor survival, but its role in tumorigenesis and antitumor immunity remains unclear. We found that expression of MAGE-A4 was highly associated with the loss of PTEN, a tumor suppressor, in human non–small cell lung cancers (NSCLC). Here, we show that constitutive expression of human MAGE-A4 with Pten loss in mouse airway epithelia results in metastatic adenocarcinoma. Tumors showed distinct enrichment in IgA+ CD138+ CXCR4+ plasma cells (PCs) and increased expression of …

Comprehensive Sumo Proteomic Analyses Identify Hiv Latency-Associated Proteins In Microglia., Fergan Imbert, Dianne Langford

Rowan-Virtua School of Osteopathic Medicine Departmental Research

SUMOylation, the post-translational modification of proteins by small ubiquitin-like modifiers, plays a critical role in regulating various cellular processes, including innate immunity. This modification is essential for modulating immune responses and influencing signaling pathways that govern the activation and function of immune cells. Recent studies suggest that SUMOylation also contributes to the pathophysiology of central nervous system (CNS) viral infections, where it contributes to the host response and viral replication dynamics. Here, we explore the multifaceted role of SUMOylation in innate immune signaling and its implications for viral infections within the CNS. Notably, we present novel proteomic analyses aimed at …

Thromboelastography Versus Thromboelastometry For Unfractionated Heparin Monitoring In Adult Patients On Extracorporeal Membrane Oxygenation, Ellen B Yin, Arthur W Bracey, Subhasis Chatterjee

Faculty, Staff and Students Publications

Background: Monitoring the anticoagulant effect of unfractionated heparin (UFH) in extracorporeal membrane oxygenation (ECMO) patients is complex but critically important to balance the risks of treatment related bleeding and circuit thrombosis. While guidelines recommend using more than one method to monitor UFH activity, the use of thromboelastometry (ROTEM) to monitor UFH in ECMO patients has not been investigated in detail.

Methods: This is an observational, single-center retrospective study looking at adult ECMO patients on UFH that had ROTEM and thromboelastography (TEG) tests obtained concurrently. A total of 20 samples were obtained from nine patients during the study period, …

The Role Of The Triglyceride-Glucose Index As A Biomarker Of Cardio-Metabolic Syndromes, Verena Gounden, Sridevi Devaraj, Ishwarlal Jialal

Faculty, Staff and Students Publications

BACKGROUND: The Triglyceride-glucose (TyG) index represents a simple, cost-effective, and valid proxy for insulin resistance. This surrogate marker has also been proposed as a predictor of metabolic and cardiovascular disease (CVD). In this descriptive review, we aimed to assess the utility of the TyG index as a predictive biomarker of cardiometabolic diseases.

METHODS: A search was conducted in PubMed, and Web of Science to identify cross-sectional and more importantly prospective studies examining the use of the TyG index as a predictive biomarker. The following terms were utilized in addition to the TyG index: "insulin resistance", "metabolic syndrome", "diabetes"; "cardiovascular diseases". …

Prenatal Identification Of Intracardiac Mass Expedites Surgical Management Of Capillary-Venous Malformation, Derek M Norton, Mounica Y Rao, Jianhong Zhang, M John Hicks, Anitha Parthiban, S Kristen Sexson Tejtel

Faculty, Staff and Students Publications

Fetal and neonatal cardiac tumors are rare and often benign. Clinical presentation is primarily related to mass effect, pericardial effusion or arrhythmia. Prenatal detection can assist with risk assessment and inform optimal delivery plan and postnatal management. We report a fetus with a right atrial mass discovered in the third trimester. After successful surgical resection, pathology confirmed the mass to be a capillary-venous malformation, which are rare and challenging to diagnose. The true incidence of these vascular malformations within cardiac spaces is difficult to discern given the historic classification of numerous different vascular malformations under the umbrella term hemangioma.

Alternatively Spliced Map4 Isoforms Have Key Roles In Maintaining Microtubule Organization And Skeletal Muscle Function, Lathan Lucas, Larissa Nitschke, Brandon Nguyen, James A Loehr, George G Rodney, Thomas A Cooper

Faculty, Staff and Students Publications

Skeletal muscle cells (myofibers) are elongated non-mitotic, multinucleated syncytia that have adapted a microtubule lattice. Microtubule-associated proteins (MAPs) play roles in regulating microtubule architecture. The most abundant MAP in skeletal muscle is MAP4. MAP4 consists of a ubiquitous MAP4 isoform (uMAP4), expressed in most tissues, and a striated-muscle-specific alternatively spliced isoform (mMAP4) that includes a 3,180-nucleotide exon (exon 8). To determine the role of mMAP4 in skeletal muscle, we generated mice that lack mMAP4 and express only uMAP4 due to genomic deletion of exon 8. We demonstrate that loss of mMAP4 leads to disorganized microtubule architecture and intrinsic loss of …

Candida Albicans Farnesol Synthesis And Secretion, Daniel J. Gutzmann

School of Biological Sciences: Dissertations, Theses, and Student Research

Candida albicans is a polymorphic fungus and opportunistic commensal found primarily in the gastrointestinal and skin of healthy individuals. Several barriers prevent C. albicans from causing disease including a healthy immune system and microbiome. When these barriers become comprised, C. albicans can transition to a pathogen and disseminate through the intestinal mucosa leading to life-threatening bloodstream and invasive infections with mortality rates of up to 64%. Morphogenic plasticity is key to this transition and impacts virulence, adaptation to different host environments, and evasion of host immune responses. One regulator of morphogenesis is farnesol. Farnesol is a secondary metabolite of …
