Morgan Bustamante, Juliana G E Bartels, Aidan Lee, Natalie J. Kane, Rose Reynolds, Theodore C. White, Mark A. Hoffman, Jennifer Head, Justin V. Remais

Manuscripts, Articles, Book Chapters and Other Papers

Fungal diseases are an emerging public health threat, yet their epidemiology remains poorly understood due to limited surveillance. Electronic health record (EHR) datasets offer opportunities for studying fungal diseases, but their national representativeness is unclear. We compared inpatient encounters for aspergillosis and histoplasmosis between Oracle EHR Real World Data (OERWD) and the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP NIS), a nationally representative discharge-derived database. We analyzed inpatient encounters from both databases and applied calibration weights to OERWD to improve alignment with national benchmarks. Relative differences (RDs) in encounter counts were compared using Wald tests. Survey-weighted quasibinomial models …

Increased Backbone Rigidity Of Artificial Transcription Factors, Jasmine Glover, Emma Otey, Joanna K. Kwao, Nicholas Truex

Senior Theses

Programming DNA-binding proteins is an effective strategy for developing therapeutics that regulate gene expression. These proteins can directly bind to DNA to activate or repress transcription of specific genes. Zinc finger proteins are a class of DNA-binding proteins commonly found in eukaryotic organisms. Their DNA-binding function is derived from unique amino acid sequences within each domain that recognizes specific nucleotides, allowing each finger to selectively recognize three DNA base pairs. Adjoining of multiple domains in tandem allows recognition of a specific DNA sequence. Artificial transcription factors can be made of multiple zinc finger domains arranged in tandem and engineered to …

Strategic Resource Management In Pandemics: Integrating Capacity Planning With Non-Pharmaceutical Interventions For Covid-19, Ozlem Cosgun, Eyyub Kibis, Ali Dag, Burak Cankaya

Department of Information Management and Business Analytics Faculty Scholarship and Creative Works

The COVID-19 pandemic underscored the urgent need for integrated healthcare resource planning to manage patient surges and reduce mortality. This study presents a novel optimization-based framework that jointly considers healthcare capacity planning and non-pharmaceutical interventions (NPIs), including mask mandates, social distancing, and quarantining. The framework extends traditional compartmental models by distinguishing patient categories—such as hospitalized non-ventilator patients, ventilated patients, and ICU admissions—within a mixed-integer programming (MIP) structure that remains computationally tractable. Applied to the COVID-19 outbreak in New York City, the model optimizes the allocation of hospital beds and ventilators while minimizing deaths. Results show that combining high-effectiveness NPIs with …

"I Need Help!": Can Ashwagandha Reduce Inflammation-Driven Oxidative Stress Without Inducing Cytotoxicity In Macrophages?, Caitlyn Pinaga

Posters - 2026

Ashwagandha has been shown to reduce inflammation in humans by lowering pro-inflammatory cytokines and oxidative stress markers, helping regulate immune responses. It is commonly used to support conditions linked to chronic inflammation, such as stress-related disorders, arthritis, and metabolic imbalance. THP-1 macrophages are a part of the body's immune response to inflammation. While they produce a lot of different responses to inflammation, one of them is the production of Reactive Oxygen Species (ROS). N-acetylcysteine (NAC) is established to be a powerful antioxidant and is used as a positive control. My study aims to understand how ashwagandha, a popular supplement, affects …

Biology

Amphibious animals, such as frogs, are found at the intersection of aquatic and terrestrial ecosystems. They may serve as keystone and sentinel species and play key roles in nutrient cycling and food webs. In recent decades, amphibians have experienced drastic population declines due to habitat loss, climate change, and disease. These declines have prompted investments in ex situ conservation and captive breeding programs, which aim to reduce extinction risk by creating assurance colonies and reintroducing individuals once threats are mitigated. A critical component of these programs is proper husbandry, which ensures the health and longevity of captive populations and their …

Mitochondria Dynamics In Microglia During Health, Inflammation, And Aging, Alicia Nicole Pietramale

Dartmouth College Ph.D Dissertations

Microglia continually surveil the brain, allowing for rapid detection of tissue damage or infection. Microglial metabolism is linked to tissue homeostasis, yet how mitochondria are subcellularly partitioned in microglia and dynamically reorganize during surveillance, injury responses, and phagocytic engulfment in the intact brain has remained unclear. In this dissertation, I combine intravital imaging, ultrastructural analyses, and metabolic and cytoskeletal markers to investigate how mitochondrial organization relates to microglial function across health, inflammation, and aging.

I first show that microglial processes diverge in their mitochondrial content, with some containing multiple mitochondria while others are completely void. This heterogeneous partitioning is conserved …

A Review Of Yellow Fever: Epidemiology, Pathogenesis, Clinical Manifestations, Treatment, Prevention, And Prognosis, Farah Ebrahim, Samina Somji, Reena Shah, Salim Surani

Internal Medicine, East Africa

Yellow fever is a mosquito-borne viral illness caused by the yellow fever virus (YFV), a member of the Flaviviridae family. Despite the availability of an effective live-attenuated vaccine, the disease remains endemic in regions of Africa and South America. Transmission occurs primarily via an infected mosquito called Aedes aegypti, with distinct urban, sylvatic, and intermediate transmission cycles. Clinically, infection ranges from mild febrile illness to severe disease, which is characterized by jaundice, hemorrhage, and multiorgan failure. Pathogenesis involves viral replication in hepatocytes, immune-mediated injury, and dysregulated inflammatory responses, leading to characteristic hepatic mid-zone necrosis. Diagnosis relies on molecular detection …

Evaluation Of Tick-Derived Peptides For Transmission-Blocking Vaccine Candidates, Madelyn Futral

Honors Theses

The lack of effective preventive measures for tick-borne diseases represents a major public health challenge. Transmission-blocking vaccines targeting tick molecules essential for feeding or reproduction could provide a sustainable and broad-spectrum solution. In this study, we evaluated two tick-derived proteins as potential vaccine antigens, subolesin, a key regulator of blood-feeding and cellular processes, and vitellogenin, a protein involved in egg development. Using bioinformatic tools, we identified immunogenic peptide sequences from each protein and chemically conjugated them to virus-like particles (VLPs) to enhance antigen presentation. C57BL/6 mice were immunized intradermally with VLP-peptide conjugates, followed by a booster dose. Blood and spleen …

Effects Of Kiwifruit Extract On Apoptosis And Cytokine Production In Inflamed Thp-1-Derived Macrophages, Adrian Cruz, Isbella Brigman

Posters - 2026

White blood cells are essential components of the immune system involved in helping defend the body against infections. Macrophages are a type of white blood cell that play a major role in stimulating and regulating the inflammatory response. Inflammation is a natural response of the immune system to infection, injury, or harmful stimuli. Scientific research commonly studies inflammation by exposing immune cells to lipopolysaccharide (LPS). Macrophages stimulated with LPS undergo changes in cell processes such as apoptosis which is programmed cell death. Apoptosis is crucial for the immune system that helps eliminate infected or damaged cells to prevent the spread …

The Effects Of Mycoplasma Pneumoniae Cards Toxin On M2 Macrophage Polarization And Formation, Ria Modi

Posters - 2026

Macrophages are key cells of the innate immune system, playing essential roles in host defense, tissue homeostasis, and inflammation. Depending on stimuli, macrophages can polarize into distinct functional phenotypes, characterized as classically activated (M1) or alternatively activated (M2) macrophages. M2 macrophages are associated specifically with anti-inflammatory responses, tissue repair, and immune regulation. They contribute to wound healing and can regulate host responses during infection. Community-acquired respiratory distress syndrome (CARDS) toxin, a key virulence factor of Mycoplasma pneumoniae, plays a role in altering host immune responses, but its impact on M2 macrophage function and polarization remains unclear.

Hyperglycemia And Mycoplasma Pneumoniae Cards Toxin Impacts On Lung Epithelial And Fibroblast Injury And Recovery, Alejandra Y. Delgado, Naila Villagomez, Shuri Magdalene

Posters - 2026

Mycoplasma pneumoniae CARDS toxin induces cytotoxicity and inflammation in lung epithelial cells²·¹⁰·¹¹, while hyperglycemia independently elevates ROS and disrupts fibroblast repair¹·⁵·⁸, contributing to the heightened respiratory infection severity seen in diabetic patients¹. However, the interaction between hyperglycemic conditions and CARDS toxin-induced lung injury remains unexplored.

This study investigates how increasing high-glucose (HG) pre-conditioning modifies CARDS toxin-induced injury and recovery in A549⁶ and IMR-90⁷ cells compared to normal glucose (NG ≈ 5mM) controls. We hypothesized that increasing glucose pre-conditioning concentrations would produce a dose-dependent increase in CARDS toxin-induced oxidative stress¹² and inflammatory cytokine production¹⁵ in IMR-90 and A549 compared with normal …
