Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Understanding the atomistic basis of multi-layer mechanisms employed by broadly reactive neutralizing antibodies of the SARS-CoV-2 spike protein without directly blocking receptor engagement remains an important challenge in coronavirus immunology. Class 4 antibodies represent an intriguing case: they target a deeply conserved, cryptic epitope on the receptor-binding domain yet exhibit variable neutralization potency across subgroups F1 (CR3022, EY6A, COVA1-16), F2 (DH1047), and F3 (S2X259). The molecular basis for this variability is not fully understood. Here, we employed a multi-modal computational approach integrating atomistic and coarse-grained molecular dynamics simulations, binding free energy calculations, mutational scanning, and dynamic network analysis to elucidate …

Air Pollution And Diseases: Signaling, G Protein-Coupled And Toll Like Receptors, Isabella Cattani-Cavalieri, Katrina F. Ostrom, Jordyn Margolis, Rennolds S. Ostrom, Martina Schmidt

Pharmacy Faculty Articles and Research

Air pollution is a significant public health issue that impacts lung health, particularly in vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory conditions. Both natural and anthropogenic sources of air pollution give rise to a variety of toxic compounds, including particulate matter (PM), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and polycyclic aromatic hydrocarbons (PAHs). Exposure to these pollutants is strongly associated with the development and exacerbation of respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and idiopathic pulmonary fibrosis (IPF). Notably, early life exposure to pollutants such as …

This analysis reports the effects of computer assisted vacuum thrombectomy on RV function.

METHODS: Eligible patients for the single-arm, prospective, international, multicenter STRIKE-PE (A Prospective, Multicenter Study of the Indigo Aspiration System Seeking to Evaluate the Long-Term Safety and Outcomes of Treating Pulmonary Embolism) cohort study are adults with acute PE with symptoms for ≤14 …

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 …

Beyond Smoking: A Geospatial Investigation Of Factors Associated With Lung And Bronchus Cancer Risk In Pennsylvania, Tesla D. Dubois, Daniel Wiese, Kevin A. Henry, Shannon M. Lynch

Kimmel Cancer Center Faculty Papers

INTRODUCTION: While smoking is the leading cause of lung and bronchus cancer (LBC), additional exposures have been implicated and may explain the rise in LBC among never-smokers. To better understand the spatial distribution of LBC incidence and associated risk factors, this study aims to identify geographic areas with significantly elevated incidence rates in Pennsylvania and investigate the potential underlying risk factors.

METHODS: Using cancer registry data aggregated to the census tract level, spatial scan statistics were applied to detect areas of higher-than-expected LBC incidence across the state. Associations were then tested between census tract inclusion in a high-incidence area and …

Beyond Keeping The Lights On: Covid-19’S Impact On Lower Mississippi River Valley Museums And Public History Sites, Liz Skilton, Ian Beamish

Department of History

This article reviews the impact of the COVID-19 pandemic on public history sites and museums along the Lower Mississippi River Valley between 2020 and 2024. Constructed from interviews with sixty-seven sites across a four-year period, it uses a regional approach to examine how pandemic closures, reopening processes, and adaptations impacted public history sites and museums in the short-, medium-, and long-term, arguing that the pandemic created lasting changes through adaptation rather than large-scale closure of public history institutions. It concludes with an assessment of what can be learned from the pandemic period’s effect on public history.

Overcoming Vaccine-Associated Enhanced Respiratory Disease In Swine Flu With Lipid Nanoparticle-Dna Technology, The Nguyen

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The two primary challenges in developing vaccines against swine influenza A virus (IAV-S) are the continuous viral evolution and vaccine-associated enhanced respiratory disease (VAERD). Current vaccine strategies share a common limitation: the significant time required for licensing updated vaccines. Moreover, the strain selection for vaccine updates depends entirely on predictions, raising the risk that chosen strains may not match circulating viruses. Such mismatches not only reduce vaccine efficacy but also risk exacerbating disease severity through VAERD. Here, in this thesis, we developed and evaluated a novel DNA-based vaccine platform designed to address the need for rapid updates in response to …

Duhadaway, Erika Sutanto-Ward, Maurice T. Hampton, Serguei V. Kozlov, George C. Prendergast, Alexander J. Muller

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Strategies for deploying indoleamine 2,3-dioxygenase 1 (IDO1)-targeted therapies for use against cancer have focused on IDO1's role in promoting peripheral immune tolerance that shields tumors from effector T cells. However, preclinical investigation of both primary and metastatic tumor development in the lungs has uncovered a previously unappreciated role for IDO1 in directing a counterregulatory response to interferon (IFN)-γ that realigns the local inflammatory environment to promote tumor neovascularization. Understanding how to therapeutically leverage the ability of IDO1 inhibitors to subvert inflammatory neovascularization within the tumor microenvironment has potential ramifications for future clinical development of these compounds.

Myocardin Effector Proteins Affect Tgf-Beta-Induced Myofibroblast Differentiation In Ipf Cells, Allison Gonzalez

Biotechnology Theses

Idiopathic pulmonary fibrosis (IPF) is an incurable interstitial lung disease defined by the progressive, irreversible scarring of the tissues between the lung’s alveoli. To date, only two drugs have received approval for treatment. However, these medications are not considered cures since they do not stop the progression of the disease. A deeper understanding of the mechanisms underlying IPF could aid in discovering a cure. We recently found that myocardin (MyoCD) regulates SMAD2/3 transcription factors in the TGF-β signaling pathway and governs the genes involved in pleural fibrosis. However, it is unclear whether MyoCD plays a critical role in IPF by …

Utah Conference on Community Engagement

Oral health is a critical component of overall health, significantly influencing systemic diseases and the quality of life in older adults. Conditions such as xerostomia, swallowing difficulties, and poor oral self-care are associated with aspiration pneumonia. Integrating oral health into healthcare in long-term care facilities (LTCFs) is essential for preventing various conditions and improving quality of life. Effective oral hygiene is crucial in avoiding non-ventilator hospital-associated pneumonia by reducing oral biofilm and lowering the risk of pneumonia. Nurses' knowledge and care in oral health across healthcare settings are vital for positive health outcomes. Revising nursing curricula to incorporate oral health …

Identification And Preclinical Assessment Of Novel Therapeutic Modalities In Environmental Exposure-Induced Lung Disease, Aaron D. Schwab

Theses & Dissertations

Environmental lung diseases are preventable respiratory conditions either caused or made worse by inhaled environmental exposures. Contemporarily, environmental lung diseases are most associated with workplace exposures given specific occupational processes aerosolize inflammatory agents that can be inhaled at high concentrations. Although a considerable amount is known regarding immunoglobulin (Ig)E-mediated responses to environmental exposures, little is known about non-IgE mediated respiratory conditions resulting from lipopolysaccharide (LPS)-enriched organic dust exposure(s). Chronic respiratory diseases such as asthma, hypersensitivity pneumonitis, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis have all been identified as environmental lung diseases caused or exacerbated by such environmental dusts. Therapeutic …
