Dissertations, Theses, and Projects

Inflammation is an important part of healing, but prolonged inflammation or inflammatory disease can cause excess pain and tissue damage. Hydrogen-rich water therapies have shown to have positive effects on this wide variety of conditions and may have a role in future therapeutic intervention for inflammatory conditions and acute injury care. Hydrogen is a commonly known element that has recently been the subject of scientific studies to analyze its beneficial properties when used as a therapeutic intervention. Hydrogen is physically the smallest element on the periodic table, and when two hydrogen atoms combine to form H2, it is known as …


The Role Of Magnesium Supplements In The Management And Prevention Of Headache Disorders, Tatum Schroeder Apr 2026

The Role Of Magnesium Supplements In The Management And Prevention Of Headache Disorders, Tatum Schroeder

Libraries Undergraduate Research Award (LURA) Winners

Much of the global population suffers from headache disorders like migraine. Because there are so many triggers and unknown explanations for migraine, it can be hard to find effective treatments for it. There are some studies that point to inflammation as either a cause or result of headache disorders; therefore, it is natural that we should explore the possibility of inflammation reducing factors when considering treatment options. The factor being explored in this review is magnesium supplementation, which has been shown to reduce inflammation by decreasing the amount of calcitonin-gene-related-peptide (CGRP) in circulation. There is a clear link between migraine …

Pharmacy Faculty Articles and Research

Background:

Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by synovial hyperplasia, persistent inflammation, and joint destruction. Targeted inhibition of intracellular signaling pathways, such as JAK-STAT, has improved RA treatment outcomes, though safety and selectivity remain as concerns. Brepocitinib, a dual TYK2/JAK1 inhibitor, has shown clinical efficacy in the management of autoimmune diseases, yet its mechanistic impact on synoviocytes remains underexplored.

Objectives:

To investigate the molecular and functional effects of brepocitinib on MH7A and RA-FLS synoviocytes, a key effector cell type in RA pathogenesis.

Methods:

MH7A and RA-FLS cells were treated with brepocitinib (0.5 µM, 1 µM, and 5 …

Cytomegalovirus As A Potential Trigger For Acute Coronary Syndrome: A Case Of Nstemi In A Previously Healthy Patient, Hussam Al Hennawi, Muhammad Sabri, David Teng, Maxwell Berman, Botros Shenoda

Abington Jefferson Health Papers

Cytomegalovirus (CMV) infection has been implicated in endothelial dysfunction and atherogenesis, yet its role as a potential trigger for acute coronary syndrome (ACS) remains underrecognized. We present a case of a 32-year-old male with no prior medical history who developed non-ST elevation myocardial infarction (NSTEMI) and was subsequently found to have active CMV infection. The patient had no known history cardiovascular disease, though subsequent testing did reveal additional underlying risk factors. This case highlights the need to consider infectious etiologies, including CMV, as contributors to ACS in young, otherwise apparently healthy individuals. Understanding the interplay between viral infections and atherosclerotic …


Inflammatory Co-Regulation Of Voltage-Gated Sodium Channels And Na,K-Atpase In Metastatic Breast Cancer, Steven D. Scahill, Kelly Jean Sherman, Dennis Paul Dec 2025

Inflammatory Co-Regulation Of Voltage-Gated Sodium Channels And Na,K-Atpase In Metastatic Breast Cancer, Steven D. Scahill, Kelly Jean Sherman, Dennis Paul

School of Graduate Studies Faculty Publications

Sodium regulation is a potentially major driver of cancer metastasis. Voltage-gated sodium channels (VGSCs) and Na,K-ATPase are sodium transporters that are upregulated in many advanced carcinomas and are implicated as metastatic drivers. However, little is known about what drives this overexpression, how these proteins influence metastatic behavior, or whether these complementary sodium transporters are co-regulated in cancer. Using sodium transporter regulation in healthy neurons as a model, the present study demonstrated that the inflammatory mediator tumor necrosis factor alpha (TNFα) affects the expression of VGSCs and Na,K-ATPase in an in vitro model of metastatic breast cancer. Acute TNFα challenge increased …

School of Graduate Studies Faculty Publications

Growing evidence suggests that psychiatric disorders are characterized by a prolonged inflammatory state, which may influence the efficacy of compounds targeting serotonin. Serotonin is a key signaling molecule in neuroplasticity of the adult hippocampus and involved in antidepressant action. Recent in vitro studies indicate the neurotransmitter may also facilitate the response to inflammation and potentially modulate microglial function towards neuroprotection. Using Tph2−/− rats depleted of brain serotonin, we examined microglial expression of various serotonin receptors (5-HTRs) in vivo in both the hippocampus and prefrontal cortex and assessed mRNA levels of cytokines and brain-derived neurotrophic factor (BDNF). We observed age-dependent and …


Probiotic Intervention In Managing Chronic Stress, Bianca Opdenbosch Oct 2025

Probiotic Intervention In Managing Chronic Stress, Bianca Opdenbosch

PANDION: The Osprey Journal of Research and Ideas

Chronic stress can induce gut dysbiosis which contributes to the dysregulation of the gut-brain axis and leads to anxiety and depressive-like symptoms. The gut-brain axis relies on nervous, immune, and endocrine interactions. Gut dysbiosis, an imbalance within the gut microbiome, disrupts gut-brain communication, impairing gut barrier integrity, inflammation regulation, and hormonal and neurotransmitter production. These gut changes contribute to mood disorders resulting from stress, and thus it is important to implement dietary interventions, like probiotics, to help mitigate these effects. Research highlights the potential of probiotics to act as an intervention to combat stress-induced gut dysbiosis and replenish beneficial bacteria …


Inflammation And Detection: Rethinking The Biomarker Landscape In Gastric Cancer, Keykavous Parang, Koosha Paydary Sep 2025

Inflammation And Detection: Rethinking The Biomarker Landscape In Gastric Cancer, Keykavous Parang, Koosha Paydary

Pharmacy Faculty Articles and Research

Gastric carcinoma is a leading cause of cancer-related mortality worldwide, yet reliable noninvasive biomarkers for its early detection remain limited. As research continues to elucidate the inflammatory underpinnings of tumor initiation and progression, it has become increasingly clear that pro-inflammatory cytokines may hold promise as diagnostic adjuncts. Serum cytokines such as interleukin (IL)-1β, IL-6, IL-8, and interferon-gamma have been frequently reported as elevated in gastric cancer patients compared to healthy individuals. These molecules, known for their roles in modulating tumor-promoting inflammation, angiogenesis, and immune evasion, may serve as accessible indicators of disease presence or progression. Several studies have shown that …

Targeting Kinin B1r Attenuates Hypertension Through At1r-Dependent Mechanisms, Drew Theobald, Riley N. Bessetti, Yumei Feng Earley, Eric Lazartigues, Karen Litwa, Srinivas Sriramula

School of Medicine Faculty Publications

BACKGROUND: Neurogenic hypertension is chronically high blood pressure that is initiated and maintained through excessive sympathetic nervous system activity and has been associated with increased B1R (kinin B1 receptor) activation. We previously reported a central role for B1R in mediating inflammatory pathways in the development of deoxycorticosterone acetate salt hypertension. Additionally, we identified a causal relationship between B1R expression after Ang II (angiotensin II) stimulation, and that B1R can mediate the bidirectional interaction between neuroinflammation and oxidative stress. However, whether there are any interactions between AT1R (Ang II-type I receptor) and B1R, and if B1R can mediate the effects of …

Military personnel deployed to Iraq and Afghanistan were exposed to emissions from open-air burn pits, where plastics, metals, and medical waste were incinerated. These exposures have been linked to deployment-related respiratory diseases (DRRD) and may also impact neurological health via the lung-brain axis. To investigate molecular mechanisms, adult male rats were exposed to filtered air, naphthalene (a representative volatile organic compound), or a combination of naphthalene and carbon black (surrogate for particulate matter; CBN) via whole-body inhalation (six hours/day, three consecutive days). Lung, brain, and plasma samples were collected 24 h after the final exposure. Pro-inflammatory biomarkers were assessed using …

School of Medicine Faculty Publications

In an effort to reduce reliance on opioids for the treatment of pain in the clinic, ongoing work is testing the utility of cannabinoid drugs as a potential alternative for treatment of chronic pain. We tested chronic delta-9 tetrahydrocannabinol (THC) vapor inhalation effects on intrinsic and synaptic properties of ventrolateral periaqueductal gray (vlPAG) neurons in male and female rats treated with complete Freund's adjuvant (CFA). We report that chronic THC vapor inhalation modulates intrinsic and synaptic properties of vlPAG neurons, including reductions in action potential firing rate and spontaneous inhibitory synaptic transmission in males, and that these effects occur specifically …

The Impact Of Perfusion Techniques On Inflammatory Response During Cardiopulmonary Bypass; A Scoping Review, Rodolfo Alfaro

Student Works

Background: Cardiopulmonary bypass (CPB) is an essential part of cardiac surgery, but it leads to SIRS (systemic inflammatory response syndrome) which in turn increases postoperative complications. There are many proposed approaches to reduce inflammation, but there is no clear best practice on the approach to use. This scoping review aims to explore the literature and classify the studies that investigate the effects of various CPB perfusion techniques on inflammatory responses to determine the possible best practices and the gaps that exist in the literature.

Methods: The present scoping review was conducted according to the Preferred Reporting Items for Systematic Reviews …


Development Of A Synthetic Biomarker System For Early Detection Of Myocardial Infarction, Kennedy Alexis Bietz Mar 2025

Development Of A Synthetic Biomarker System For Early Detection Of Myocardial Infarction, Kennedy Alexis Bietz

Honors Thesis

Every year, thousands of Americans suffer from the event of a heart attack, i.e., myocardial infarction (MI). Currently, the early detection of MI remains a challenge. We intend to solve the problem by constructing a synthetic biomarker system that would be able to recognize early warning signs of MI, such as cellular inflammation and oxidative stress. We have proposed two different pathology specific genetic sensors that act as artificial promoters to transcribe a peptide that can be secreted into the blood stream and eventually work its way into the urine and act as a reporter that can be detected through …

Intravaginal Cooling Provides Symptom Relief In Women With Vulvovaginal Candidiasis And Reduces Immunopathology In An Accompanying Mouse Model, Junko Yano, Kimberly Langdon, Michael Swor, Mairi C. Noverr, Paul L. Fidel

School of Dentistry Faculty Publications

BACKGROUND: Vulvovaginal candidiasis (VVC), caused primarily by Candida albicans, is currently treated with either prescription or over-the-counter antifungal drugs, often with variable efficacy and relapses. New and improved therapeutic strategies, including drug-free treatment alternatives, are needed. Upon overgrowth or environmental triggers, C. albicans yeast transitions into hyphae that results in an aberrant immunopathologic response by neutrophils, contributing to the characteristic vulvovaginal symptoms. The purpose of this study was to evaluate the efficacy of a patented intravaginal cooling device (Vlisse®) to provide symptom relief in women with VVC via putative reversal of C. albicans hyphae to the commensal yeast form, with …

The oral microbiome is the second largest microbial community in the human body after the gut microbiome. It includes an array of fungi, bacteria, amoebae, flagellates, archaea, and viruses, all of which are potential pathogens. This microbiome can act as a facilitator not only for protection but also for aggravation when dysbiosis occurs. Although conventional thought is this is primarily in terms of oral health issues, such as dental caries and gingival disease. The systemic effects of the oral microbiome however, are relevant to both gastrointestinal (GI) disease and non-GI disease. These systemic risks occur for several reasons, including upregulation …

Department of Medicine Faculty Publications

Micro- and nanoplastics (MNPs) are plastic particles smaller than 5 mm and 1 μm, respectively, and are emerging environmental pollutants with growing implications for human health. These particles stem from either 'primary sources', such as intentionally manufactured microbeads and industrial abrasives, or 'secondary sources', where larger plastic items break down into smaller fragments over time. Human exposure primarily occurs through ingestion and inhalation, with contaminated seafood and plastic-laden food packaging representing key routes of entry. Once ingested, MNPs can cross the intestinal barrier, accumulate in gastrointestinal (GI) tissues, and trigger biological responses. Mechanistic studies reveal that MNPs induce oxidative stress, …

Synovial Fluid Cutibacterium Acnes Antigen Is Detected Among Shoulder Samples With High Inflammation And Early Culture Growth, Krista Toler, Pearl Paranjape, Alex Mclaren, Thomas Jefferson University

Rothman Institute Papers

Background: An emerging paradigm suggests that positive Cutibacterium acnes shoulder cultures can result from either true infection or contamination, with true infections demonstrating a host inflammatory response and early culture growth. This clinical retrospective study examines the relationship between C. acnes antigen, C. acnes culture results, and inflammation.

Methods: From January 2021 to July 2023, 1,365 periprosthetic synovial fluid samples from 347 institutions were tested for shoulder infection at a centralized clinical laboratory. A biomarker scoring system based on the 2018 International Consensus Meeting (ICM) definition was utilized to assign each sample an inflammation score. Associations between inflammation, culture results, …

Review Of Mpges-1 Inhibitors Based On The Benzoxazole And Its Isostere Scaffold For The Treatment Of Inflammatory Diseases, Abdullah M. Alwagdani

Longitudinal Scholar's Project

The vital role of the prostanoid pathway in inflammation, pain, cancer, Alzheimer’s and many other diseases has attracted the drug discovery community to discover targets for therapeutic development. Although existing non-steroidal anti-inflammatory drugs (NSAIDs) inhibiting cyclooxygenases (COX) are widely used, the side effects of these NSAIDs limit the ling time medication. Microsomal prostaglandin E synthase-1 (mPGES-1) is an attractive target that is overexpressed during inflammations, and it could be a safe alternative to NSAIDs for treating inflammatory diseases.Since the discovery of mPGES-1 in 1997, many inhibitors have been developed since 2001. Only a few compounds were able to make it …

Exposure to hydrochloric acid (HCl) can provoke acute and chronic lung injury. Because of its extensive production for industrial use, frequent accidental exposures occur, making HCl one of the top five chemicals causing inhalation injuries. There are no Food and Drug Administration (FDA)-approved treatments for HCl exposure. Heat shock protein 90 (HSP90) inhibitors modulate transforming growth factor-β (TGF-β) signaling and the development of chemical-induced pulmonary fibrosis. However, little is known on the role of Heat Shock Protein 70 (HSP70) during injury and treatment with HSP90 inhibitors. We hypothesized that administration of geranylgeranyl-acetone (GGA), an HSP70 inducer, or gefitinib (GFT), an …

Post-acute sequelae of COVID-19 (PASC, "Long COVID") pose a significant global health challenge. The pathophysiology is unknown, and no effective treatments have been found to date. Several hypotheses have been formulated to explain the etiology of PASC, including viral persistence, chronic inflammation, hypercoagulability, and autonomic dysfunction. Here, we propose a mechanism that links all four hypotheses in a single pathway and provides actionable insights for therapeutic interventions. We find that PASC are associated with serotonin reduction. Viral infection and type I interferon-driven inflammation reduce serotonin through three mechanisms: diminished intestinal absorption of the serotonin precursor tryptophan; platelet hyperactivation and thrombocytopenia, …

Research outputs 2022 to 2026

Chronic pancreatitis increases the risk of developing pancreatic cancer through the upregulation of pathways favouring proliferation, fibrosis, and sustained inflammation. We established in previous studies that the ligand tumour necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) signals through its cognate receptor fibroblast growth factor-inducible 14 (Fn14) to regulate these underlying cellular processes in the chronic liver injury niche. However, the role of the TWEAK/Fn14 signalling pathway in pancreatic disease is entirely unknown. An analysis of publicly available datasets demonstrated that the TWEAK receptor Fn14 is upregulated in pancreatitis and pancreatic adenocarcinoma, with single cell RNA sequencing revealing pancreatic ductal …

10-Minute Ebd: Preferred Analgesia For Orthodontic Tooth Movement: Acetaminophen Or Nsaids?, Ryan N. Mcgovern Apr 2022

10-Minute Ebd: Preferred Analgesia For Orthodontic Tooth Movement: Acetaminophen Or Nsaids?, Ryan N. Mcgovern

The Journal of the Michigan Dental Association

This 10-Minute EBD column explores the choice between acetaminophen and NSAIDs for managing pain during orthodontic tooth movement. The author presents a scenario involving a patient's discomfort after archwire adjustment and delves into the impact of tooth movement on the periodontium. The PICO question focuses on the effectiveness of NSAIDs and acetaminophen in controlling discomfort without impeding tooth movement. The literature search reveals varying recommendations on analgesics, with some studies favoring acetaminophen. The evidence suggests that acetaminophen and short-term celecoxib are suitable choices for orthodontic analgesia. However, caution is advised in extrapolating findings from animal studies to human conditions.

Bioelectrics Publications

Background

Bacterial pneumonia is a major risk factor for acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Pseudomonas aeruginosa (PA), an opportunistic pathogen with an increasing resistance acquired against multiple drugs, is one of the main causative agents of ALI and ARDS in diverse clinical settings. Given the anti-inflammatory role of the cannabinoid-2 receptor (CB2R), the effect of CB2R activation in the regulation of PA-induced ALI and inflammation was tested in a mouse model as an alternative to conventional antibiotic therapy.

Methods

In order to activate CB2R, a selective synthetic agonist, JWH133, was administered intraperitoneally (i.p.) to C57BL/6J …


Effect Of Lactoferrin To Increase Drug Permeability Of Primary Pulmonary Mycobacterial Granulomas, Thao Nguyen, Thao Kt Nguyen Aug 2021

Effect Of Lactoferrin To Increase Drug Permeability Of Primary Pulmonary Mycobacterial Granulomas, Thao Nguyen, Thao Kt Nguyen

Dissertations and Theses (Open Access)

Despite extensive research and worldwide eradication efforts, Mycobacterium tuberculosis (Mtb) remains a major infectious pathogen to the human population with about 10 million cases of infection per year globally. The host-pathogen interaction, pulmonary granuloma formation, and Mtb adaptions result in increased complexity of the disease. Granulomas are formed by active immune responses generated during Mtb infection, and serve to contain and limit bacterial dissemination. The major mycobacterial surface mycolic acid, trehalose 6,6'-dimycolate (TDM), functions in multiple ways to enhance immune cell recruitment of sites of infection, to induce inflammation and granulomatous responses, and to initiate survival strategies for …

Recombinant Human Proteoglycan-4 Mediates Interleukin-6 Response In Both Human And Mouse Endothelial Cells Induced Into A Sepsis Phenotype, Holly A. Richendrfer, Mitchell M. Levy, Khaled A. Elsaid, Tannin A. Schmidt, Ling Zhang, Ralph Cabezas, Gregory D. Jay

Pharmacy Faculty Articles and Research

Objectives:

Sepsis is a leading cause of death in the United States. Putative targets to prevent systemic inflammatory response syndrome include antagonism of toll-like receptors 2 and 4 and CD44 receptors in vascular endothelial cells. Proteoglycan-4 is a mucinous glycoprotein that interacts with CD44 and toll-like receptor 4 resulting in a blockade of the NOD-like receptor pyrin domain-containing-3 pathway. We hypothesized that endothelial cells induced into a sepsis phenotype would have less interleukin-6 expression after recombinant human proteoglycan 4 treatment in vitro.

Design:

Enzyme-linked immunosorbent assay and reverse transcriptase-quantitative polymerase chain reaction to measure interleukin-6 protein and gene expression.

Setting: …
