Phytochemical And In-Vitro Cytotoxic Analyses Of Flavonoid Species Isolated From Chromolaena Leivensis, Luke A. Bryant

Electronic Theses and Dissertations

As a leading cause of death worldwide, cancer and its treatments remain a primary source of interest among researchers. Modern studies are looking into bioselective cytotoxicity to create new chemotherapies that do not have the same harsh side effects as those we use today. Natural product research has a promising future for the development of such treatments. Specifically, polar flavonoids may be the key to a bioselective treatment. Such flavonoid species are native to plants, often within flower petals or within the body. A natural antioxidant, they are designed not to harm healthy cells. This study focuses on the plant …

Optometric Clinical Practice

Background: Pentosan polysulfate sodium (PPS, Elmiron®) is a widely used medication to reduce pain caused by interstitial cystitis, a bladder disorder most often affecting females. PPS maculopathy is a novel form of toxic retinal disease often not recognized or mistaken for other retinal conditions such as macular degeneration due to the initial similarities on fundus exam. However, when visualized using fundus autofluorescence, affected eyes show characteristic hyper/hypo-autofluorescent patterns.

Case report: A patient taking PPS for 10 years presented with macular changes and complaints of blurry vision and nyctalopia. Clinical, electrodiagnostic, and genetic testing were performed including fundus autofluorescence and …


Titanium Dioxide: An Inquiry Into The Mechanisms And Implications Of Exposure In Gut Dysbiosis And Metabolic Disorders, Meghan Gardiner May 2026

Titanium Dioxide: An Inquiry Into The Mechanisms And Implications Of Exposure In Gut Dysbiosis And Metabolic Disorders, Meghan Gardiner

Senior Honors Theses

Titanium dioxide (TiO2) is one of the most prevalent food additives utilized in commercial products in the United States. While TiO2 was originally hailed as a nontoxic and cost-effective additive, studies are beginning to reveal that TiO2 is not as safe as it once seemed. TiO2 may contribute to the development of insulin resistance and metabolic disorders through direct and indirect mechanisms. The compound induces gut dysbiosis, leading to alterations in bacterial metabolites and pro-inflammatory cytokines, which results in the selective resistance of glucocorticoid receptors. Additionally, TiO2 itself can translocate from the gut to …

Pentobarbital is a barbiturate with sedative and anticonvulsant properties, occasionally used in pediatric patients for preoperative sedation, deep sedation during mechanical ventilation, and seizure control. Despite its long-standing clinical use, age-appropriate dosing remains challenging due to variability across studies and limited pediatric pharmacokinetic (PK) data. This study (NCT01431326) aimed to characterize the population pharmacokinetics of pentobarbital in pediatric patients (birth to 21 years) and evaluate dosing strategies using model-based simulations. A two-compartment population PK model, allometrically scaled to total body weight, adequately described pentobarbital plasma concentrations, with no additional covariates identified as significant. Simulations were conducted across four age groups: …


Investigating Sertraline‑Mediated Modulation Of Succinate Dehydrogenase To Sensitize Tmz‑Resistant Glioblastoma Cells, Supraja Mallapuram Apr 2026

Investigating Sertraline‑Mediated Modulation Of Succinate Dehydrogenase To Sensitize Tmz‑Resistant Glioblastoma Cells, Supraja Mallapuram

Create@State

Glioblastoma (GBM) is one of the deadliest and most common brain tumor which remains highly resistant to temozolomide (TMZ), contributing to poor patient outcomes. Literature suggests that sertraline, a widely used SSRI, disrupts mitochondrial metabolism in cancer cells. Because GBM depends heavily on succinate dehydrogenase (SDH) for oxidative phosphorylation, sertraline‑mediated SDH inhibition may increase metabolic stress and reduce functional TMZ resistance. This poster presents a literature‑based rationale and proposed experimental design to evaluate sertraline‑induced SDH modulation and its potential to sensitize TMZ‑resistant T98G glioblastoma cells. These findings will guide future experimental work.

Regorafenib Pulmonary Toxicity: A Case Of Cavitary Lung Disease And Ards Treated With Infliximab, Michael Dong, Mackenzie Kramer, Tanmay Gandhi, Gautam George

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

Regorafenib-induced pneumonitis and acute respiratory distress syndrome (ARDS) are rare and poorly characterized toxicities. We describe a 43-year-old male with metastatic colorectal cancer who developed hypoxic respiratory failure after two cycles of regorafenib. Imaging revealed cavitary lung lesions and diffuse ground glass opacities. Despite antibiotics and high-dose corticosteroids, his condition deteriorated, requiring ICU admission and mechanical ventilation. Bronchoalveolar lavage revealed bacterial pathogens, and he was treated for pneumonia. After multidisciplinary discussion, he was assessed to have regorafenib-induced pneumonitis as a major driver of his respiratory failure, and after limited steroid response, infliximab was administered with marked respiratory improvement. However, he …


Bard1: A Friend Or Foe In Pancreatic Ductal Adenocarcinoma?, Lily Zekavat, Aditi Jain Sep 2025

Bard1: A Friend Or Foe In Pancreatic Ductal Adenocarcinoma?, Lily Zekavat, Aditi Jain

Department of Surgery Faculty Papers

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive solid malignancy with poor overall prognosis and limited response to standard treatments. Growing interest in the modulation of DNA repair mechanisms, including the homologous recombination (HR) repair pathway, has opened new avenues for therapeutic development. BARD1 (BRCA1-Associated RING Domain 1) plays a complex role in tumor biology, functioning either as a tumor suppressor or as an oncogenic driver, depending on isoform expression, cellular context, and regulatory environment. In this review, we examine the dual roles of BARD1, focusing on its regulation and paradoxical activities in PDAC. We summarize evidence that BARD1 and BARD1 …


Effects Of Genetic Polymorphisms On The Oct1 And Oct2-Mediated Uptake Of Atenolol, Mollie Margaret Walton Md, Jonathan Wagner Do, Ceclia E. Villanueva Phd, Bruno Hagenbuch Phd May 2025

Effects Of Genetic Polymorphisms On The Oct1 And Oct2-Mediated Uptake Of Atenolol, Mollie Margaret Walton Md, Jonathan Wagner Do, Ceclia E. Villanueva Phd, Bruno Hagenbuch Phd

Research Days

This project characterizes the role of OCT1 and OCT2 on cellular uptake of atenolol and tests the hypothesis that OCT1 and OCT2 proteins with genetic polymorphisms, when expressed in vitro, will result in altered cellular uptake of atenolol relative to the reference genotype. This approach utilizes transiently transfected OCT1 and OCT2 cell assays to perform time-dependent atenolol uptake experiments to generate kinetics information. The goal is to provide a better understanding of polymorphisms associated with OCT1 and OCT2 expression and function as a means to individualize pharmacologic therapy for atenolol.


Fc Gamma Receptors Facilitate Antigenic Modulation Of Lilrb4 And Function As Predictive Biomarkers In Acute Monocytic Leukemia, Joshua Morse May 2025

Fc Gamma Receptors Facilitate Antigenic Modulation Of Lilrb4 And Function As Predictive Biomarkers In Acute Monocytic Leukemia, Joshua Morse

Dissertations and Theses (Open Access)

Acute monocytic leukemia (monocytic AML) is a subtype of AML marked by a proliferation of abnormal monoblasts. This subtype represents approximately 10% of AML cases. The prognosis of monocytic AML is poor, with a 5-year survival of ~30%. Most patients are diagnosed at an age when they are unlikely to survive first-line non-targeted cytotoxic chemotherapy as a bridge to hematopoietic stem cell transplant (HSCT). Even patients who achieve remission commonly relapse. This population of patients would greatly benefit from precision-targeted therapies but currently there are none approved for monocytic AML.

Leukocyte immunoglobulin-like receptor B4 (LILRB4) is an immune checkpoint expressed …

Department of Medicine Faculty Papers

Introduction: We present the first published case of turmeric-associated drug-induced liver injury (DILI) accompanied by significant ferritin elevation. Case Presentation: Our patient, a 59-year-old female with DILI caused by long-term ingestion of oral turmeric supplements, presented with painless jaundice on an annual exam. The patient’s liver function tests exhibited a hepatocellular pattern and hyperferritinemia (>2,000 ng/dL). Additional testing was negative except for heterozygosity for the H63D allele associated with hemochromatosis. A liver biopsy indicated acute hepatitis without fibrosis or stainable iron. Conclusion: Upon discontinuation of the supplement, liver enzymes normalized within a month. This case highlights the potential for …

A Peculiar Pancreatitis: Investigating The Adverse Effects Of Mesalamine, Elias Arellano Villanueva, Miguel Lopez, Alhasan Asaad, Jose Campo Maldonado

Research Symposium

Background: Acute pancreatitis (AP) is a leading cause of gastrointestinal-related hospitalizations in the United States, accounting for approximately 300,000 emergency department visits annually. It is characterized by parenchymal and peripancreatic fat necrosis accompanied by inflammation. The clinical diagnosis of AP is based on elevated serum amylase and lipase levels, characteristic imaging findings, and epigastric pain often radiating to the back. While gallstones and alcohol use are the most common causes of AP, drug-induced pancreatitis (DIP) is a rare but increasingly recognized etiology, contributing to 0.1–5% of cases. DIP is typically diagnosed by excluding other causes and is often associated with …

Epigenetic Landscapes Of Aging In Breast Cancer Survivors: Unraveling The Impact Of Therapeutic Interventions-A Scoping Review, Nikita Nikita, Zhengyang Sun, Swapnil Sharma, Amy L Shaver, Victoria Seewaldt, Grace Lu-Yao

Department of Medical Oncology Faculty Papers

Breast cancer therapies have dramatically improved survival rates, but their long-term effects, especially on aging survivors, need careful consideration. This review delves into how breast cancer treatments and aging intersect, focusing on the epigenetic changes triggered by chemotherapy, radiation, hormonal treatments, and targeted therapies. Treatments can speed up biological aging by altering DNA methylation, histone modifications, and chromatin remodeling, affecting gene expression without changing the DNA sequence itself. The review explains the double-edged sword effect of therapy-induced epigenetic modifications, which help fight cancer but also accelerate aging. Chemotherapy and targeted therapies, in particular, impact DNA methylation and histone modifications, promoting …


Takotsubo Cardiomyopathy: A Case Of The Broken Heart, Lilian Huynh, Kaylee Putney Feb 2025

Takotsubo Cardiomyopathy: A Case Of The Broken Heart, Lilian Huynh, Kaylee Putney

Annual Research Symposium

Takotsubo cardiomyopathy (TC), or "broken heart syndrome," is a rare cardiac condition causing temporary left ventricular dysfunction due to severe stress. Though the exact cause is unclear, it mimics myocardial infarction and can lead to cardiogenic shock. Current treatment lacks specific guidelines and relies on heart failure protocols. We report a case of a patient with TC-induced cardiogenic shock, likely triggered by emotional stress. She required vasopressors, a percutaneous intervention, an Impella device, and guideline-directed medication therapies. This case underscores the significance of establishing guideline optimizations for managing TC and cardiogenic shock.

Effects Of Sex And Estrous Cycle On Extended-Access Oxycodone Self-Administration And Cue-Induced Drug Seeking Behavior, Bhumiben P Patel, Jessica A Loweth Nov 2024

Effects Of Sex And Estrous Cycle On Extended-Access Oxycodone Self-Administration And Cue-Induced Drug Seeking Behavior, Bhumiben P Patel, Jessica A Loweth

Rowan-Virtua School of Osteopathic Medicine Departmental Research

INTRODUCTION: Increasing evidence indicates that sex is a factor that impacts the abuse liability and relapse vulnerability of prescription opioids like oxycodone. However, while women are more likely than men to be prescribed and to use these drugs, the impact of sex and ovarian hormones on prescription opioid use and relapse vulnerability remains unclear. Accurately assessing these measures is complicated by the fact that chronic opioid exposure can lower ovarian hormone levels and cause cycle irregularities.

METHODS: Adult male and female Sprague-Dawley rats self-administered oxycodone (0.1 mg/kg/infusion) under extended-access conditions (6 h/day, 10 days) followed by forced abstinence. Separate groups …

Aberrant expression of HOX and MEIS1 family genes, as seen in KMT2A-rearranged, NUP98-rearranged, or NPM1-mutated leukemias leads to arrested differentiation and leukemia development. HOX family genes are essential gatekeepers of physiologic hematopoiesis, and their expression is regulated by the interaction between KMT2A and menin. Menin inhibitors block this interaction, downregulate the abnormal expression of MEIS1 and other transcription factors and thereby release the differentiation block. Menin inhibitors show significant clinical efficacy against KMT2A-rearranged and NPM1-mutated acute leukemias, with promising potential to address unmet needs in various pediatric leukemia subtypes. In this collaborative initiative, pediatric and adult hematologists/oncologists, and stem cell …

Protein structure has been well established to play a key role in determining function; however, intrinsically disordered proteins and regions (IDPs and IDRs) defy this paradigm. IDPs and IDRs exist as an ensemble of structures rather than a stable 3D structure yet play essential roles in many cell-signaling processes. Nearly all Ras superfamily GTPases are tethered to membranes by a lipid tail at the end of a flexible IDR. The sequence of the IDR is a key determinant of membrane localization, and interaction between the IDR and the membrane has been shown to affect signaling in RAS proteins through the …


Selective Serotonin Reuptake Inhibitors And Pharmacological Resetting Of The Mind, Ion G. Motofei, David L. Rowland Apr 2024

Selective Serotonin Reuptake Inhibitors And Pharmacological Resetting Of The Mind, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

Mental activity is capable of processing analytical data (mathematics, physics, socio-political science, philosophy, etc.) similar to computer software. At the same time, mental activity largely depends on the brain, which works like a hard component of a computer. While the computer stores data on a physical medium, mental activity and data are supported by physiological mechanisms that are constantly operating (both in wakefulness and sleep). For this reason, the lack of brain oxygenation even for short periods of time (5-10 minutes) causes the loss of all data, including the disappearance of the individual's existence as a mental entity. This means …
