Understanding Lyme Iaci: Implications For Camp Nurses, Mary Tobin

CompassPoint

Lyme Infection-Associated Chronic Illness (Lyme IACI) is a term adopted by the U.S. National Academies of Sciences, Engineering, and Medicine (NASEM) to describe persistent, often debilitating symptoms that follow Lyme disease infection. Affecting an estimated 10–20% of individuals treated for Lyme disease, Lyme IACI includes fatigue, musculoskeletal pain, cognitive dysfunction, and sleep disturbances that can last months or even years despite standard antibiotic therapy (NASEM, 2025). Unlike acute Lyme disease, Lyme IACI is not well understood and lacks validated diagnostic tools or biomarkers, making it a challenge to diagnose or treat for clinicians and caregivers—especially those working with children in …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Mitochondrial dysfunction caused by abnormally high RyR2 (ryanodine receptor) activity is a common finding in cardiovascular diseases. Mechanisms linking RyR2 gain of function with mitochondrial remodeling remain elusive. We hypothesized that RyR2 hyperactivity in cardiac disease increases [Ca 2+ ] in the mitochondrial intermembrane space (IMS) and activates the Ca 2+ -sensitive protease calpain, driving remodeling of mitochondrial cristae architecture through cleavage of structural protein OPA1 (optic atrophy protein 1).

METHODS: We generated a highly arrhythmogenic rat model of catecholaminergic polymorphic ventricular tachycardia, induced by RyR2 gain-of-function mutation S2236L(Ser2336Leu)(+/-) . We created a new biosensor to measure IMS-[Ca2+ ] …

A Comprehensive Study Of C-Kit-Expressing Amacrine Cells In The Mammalian Retina, Zheng Jiang, Wen Shen

Faculty, Staff and Students Publications

Amacrine cells assemble complex circuits in the inner retina, where they integrate, modulate, and relay spatial and temporal information to retinal ganglion cells. Nevertheless, their organization and functional diversity are still not fully understood. In this study, we identify a distinct group of amacrine cells that express the stem cell factor receptor-c-Kit. Using combined techniques of anti-CD117 (c-Kit) immunolabeling, confocal imaging, and computational algorithms, we characterize the morphological features and spatial distribution of the c-Kit-expressing amacrine cells. Our results show that c-Kit-expressing amacrine cells are GABA-positive neurons with medium to wide dendritic fields that stratify within the specific strata in …

Grapes Cure Cancer: My First Molecular Docking Analysis Of Resveratrol Binding To Anti-Apoptotic Protein Bcl-2: In Silico, Sydni Ann Kolokoltsev, Vishwas Joshi

Publications and Research

B-cell lymphoma 2 (BCL-2) is an anti-apoptotic protein frequently overexpressed in cancer, enabling tumor cells to evade programmed death. Resveratrol, a grape-derived polyphenol, has reported anticancer properties. Here we performed in silico docking of resveratrol to human BCL-2 using AutoDock Vina. The best-ranked pose exhibited a predicted binding free energy of 8.0 kcal/mol and formed at least one short hydrogen bond (~1.8 Å) with pocket residues. These results support further evaluation of resveratrol as a potential modulator of BCL-2-mediated apoptosis.

The Triangular Interaction Between Dietary Polyphenols, Gut Microbiota, And Metabolic Syndrome, Emily Bayliss

Senior Honors Theses

Type 2 diabetes mellitus (T2DM) is a growing global health concern characterized by peripheral insulin resistance as well as impaired insulin secretion from pancreatic β-cells. Emerging evidence suggests that the gut microbiome, specifically gut dysbiosis, an imbalance in the gut microbiome, is a critical modulator of the pathophysiology of T2DM. Dietary polyphenols, a diverse group of bioactive compounds that are abundant in plant-based foods, have recently gained attention for their potential to attenuate metabolic disorders through their antioxidant and anti-inflammatory properties as well as through modulating the composition and activity of gut microbes, thereby attenuating dysbiosis. However, the diabetic state …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Right ventricular failure (RVF) is the primary determinant of outcomes in pulmonary hypertension (PH). Coronary microvascular dysfunction (CMD), defined by capillary rarefaction and endothelial dysfunction, may contribute to RVF but remains poorly characterized. CMD, defined by capillary rarefaction and endothelial dysfunction, may contribute to RVF through impaired myocardial oxygen delivery and fibrotic remodeling.

OBJECTIVES: To characterize right ventricle (RV) CMD and myocardial fibrosis in explanted human hearts and examine associations with echocardiographic and hemodynamic indices of RVF across PH subtypes.

METHODS: We retrospectively analyzed 57 adult patients who underwent orthotopic heart transplantation at 3 institutions (2023-2024). Explanted hearts were …

Molecular Pathway Dysregulation In Chronic Liver Disease: Metabolic And Mechanotransductive Drivers Of Hepatic Pathophysiology, Samantha Harvat

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

Metabolic dysfunction–associated steatotic liver disease (MASLD) represents a rapidly growing cause of chronic liver injury, yet the molecular interactions linking metabolic stress, inflammation, fibrosis, and hepatocellular carcinoma (HCC) remain incompletely defined. This thesis integrates transcriptomic analyses across multiple GEO datasets to identify coordinated metabolic, inflammatory, and mechanotransductive pathways that collectively drive disease progression.

Analysis of human liver biopsy datasets (GSE126848 and GSE89632) revealed consistent suppression of glycolysis, β-oxidation, and oxidative phosphorylation across MASLD and MASH samples, accompanied by modest compensatory TCA cycle activation. These alterations reflect impaired metabolic flexibility, mitochondrial stress, and increased ROS susceptibility. Concurrently, cytokine-network enrichment demonstrated activation …

Community Health Promoters’ Experiences In Mitigation Of Cardiovascular Diseases In Lari Sub-County - Kiambu County, Kenya, Emily Njeri Muchina

MSc in Advanced Practice Nursing

Background: Cardiovascular diseases (CVDs) are a rising public health issue in low- and middle-income countries, including Kenya, where there is an escalation of their deaths and preventable risk factors. Community health promoters (CHPs) have a crucial role in the prevention of CVDs. Yet, low knowledge of CVD prevention and low detection of CVD risk factors characterise most underserved communities in Kenya. Little has been documented about CHPs' experiences in mitigating CVDs despite the presence of multilevel barriers and facilitators that can shape their experiences.

Aim: To gain an in-depth insight into the experiences of CHPs in mitigating CVD …

Increasing Histidyl Dipeptides In Skeletal Muscle Preserves Muscle Mass And Function In Heart Failure., Mamata Hiraman Chaudhari

Electronic Theses and Dissertations

Introduction: Heart failure is a systemic disease associated with multiple comorbidities, such as skeletal muscle wasting and cardiopulmonary disease. Muscle wasting in heart failure patients is a severe comorbidity associated with decreased exercise capacity and poor quality of life. Previous reports show that oxidative stress is increased in the skeletal muscle of heart failure patients, which can directly lead to muscle wasting. However, antioxidant intervention in these patients was unable to improve cardiac function and consequently had no effect on muscle wasting. Although oxidative stress is the primary driver of skeletal muscle atrophy, no attempt has been made to examine …

Optimizing Endothelial Cell Specific Polymersome-Based Atheroprotective Therapies, Ally C. Brawner

All Theses

Atherosclerotic cardiovascular disease is the number one cause of death in the United States and the world. Every year, billions of dollars are spent in the US alone for direct treatments of this disease, especially on prescription medicines like statins. However, these medications have been unable to curtail global mortality rates, partially because they do not target the entirety of atherosclerotic pathophysiology. A key area of this pathophysiology is that atheroprone arteries typically include pro-inflammatory endothelial cells that exhibit decreased levels of apoAI-mediated cholesterol efflux and an increased release of adhesion molecules, such as VCAM-1. The objective of my project …

Defining The Causal Contribution Of The Gut Microbiota To Cardiomyopathy Pathogenesis As A Basis For Developing Microbiome-Targeted Therapies, Xu Shi

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Heart failure (HF) is a leading cause of morbidity and mortality worldwide, placing substantial clinical and economic burdens on society. Although advances in therapy have improved patient outcomes, the biological mechanisms that drive HF onset and progression remain incompletely understood. Increasing evidence suggests that the gut microbiota, the trillions of microorganisms residing in the gastrointestinal tract, plays a key role in some forms of heart disease, especially cardiovascular disease. Moreover, gut microbial dysbiosis has been associated with systemic inflammation, metabolic imbalance, and immune dysregulation, all of which contribute to the pathophysiology of HF. Cardiomyopathy, a primary disorder of the heart …
