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 …

Analysis Of Terpenes In Cannabis Flowers Using Gas Chromatography Via Headspace-Solid Phase Microextraction (Hs-Spme), Hannah I. Bergner

Forensic Science Master's Projects

As cannabis commercialization grows, rigorous profiling of cannabinoids, terpenes, and chemical contaminants is legally required for industry standardization and consumer safety. Terpenes are highly volatile components that dictate the unique aromatic profiles and therapeutic properties of cannabis via receptor pathways. This project focused on a gas chromatography-flame ionization detector/mass selective detector (GC-FID/MSD) combined with headspace-solid phase microextraction (HS-SPME) sampling to analyze terpenes present in four cannabis samples. Cannabis samples were tightly sealed in vials (10 mL) and heated to vaporize terpenes in the headspace above the samples, followed by the extraction of the vaporized terpenes using a polydimethylsiloxane (PDMS)-coated SPME …

Greener Synthesis Of Pdi Ligands Using A Microwave Reactor, Gabrielle E. Leonhardt, Abbigale S. Holjes, Kyle A. Grice

DePaul Discoveries

Two pyridinediimine (PDI) ligands were synthesized using green chemistry principles to minimize environmental impact and maintain synthetic efficiency. Previous syntheses require hazardous solvents and long reaction times. The reaction was carried out with a safer solvent, ethanol, and more rapidly using a CEM Discover microwave reactor. The PDI ligand was chosen for the scaffold for the aromatic core and support for different aniline derivatives. Comparative investigation of aniline electronics showed that 2,6-dimethylaniline was more successful than the electron-withdrawing electronics of 2,6-dichloroaniline. Synthesized complexes were characterized with proton nuclear magnetic resonance (NMR). The environmentally conscious microwave reaction produced effective and reproducible …

Beyond The Expected Window: A Rare Presentation Of Acei-Associated Angioedema Two Decades Into Therapy, Taiwo Ajani, Jose J. Loayza Pintado, Renzo Aller Rojas, Jorge Aboytes Trevino, Michelle Lopez

Research Colloquium

Introduction: Angiotensin-converting enzyme inhibitor–induced angioedema (ACEI-AE) is a rare but potentially serious adverse effect of a widely used class of antihypertensives. It typically presents as non-pitting, non-pruritic swelling of the face, lips, tongue, or upper airway, often without associated urticaria. Although most cases occur within the first weeks of treatment, delayed presentations, sometimes after years of stable therapy, have been increasingly recognized. The condition is bradykinin-mediated and often does not respond to standard allergy medications such as antihistamines or corticosteroids.

Case Presentation: A 56-year-old woman with a medical history of hypertension, type 2 diabetes, GERD, and seasonal allergies presented to …

The Cannabis Motivation Spectrum: Comparing Medical, Recreational And Dual Intent Users, Addyson Domian, Jacob Borodovsky

Wetterhahn Science Symposium Posters

There is a lack of a standardized definition of “medical” cannabis use in the healthcare industry, which has led to an informal, user-reported definition of medical use. Consequently, individuals who use cannabis for both medical and recreational reasons (dual intent) are not always differentiated from pure medical or pure recreational users. This study compares self-defined medical only and dual intent motivational groups relative to recreational only users to better understand how these groups differ by analyzing sociodemographic and use patterns, clinically relevant factors, and claimed cannabis-related benefits. Using data from the Qualtrics Cannabis Exposure Index survey instrument of 8836 adult …

Developing Antibodies Against Galectin-3 And Galectin-9 To Target Endometriosis, Ashleigh Burger, Noah Farnsworth, Jared J. Reisnouer, Cheyenne Vue

2026 Symposium

Endometriosis is a disease characterized by pelvic pain and the formation of endometrial-like tissue on the outside of the uterine lining. This condition affects nearly 10% of women across the globe and confirming whether someone has endometriosis requires visualization in surgery. While the specific causes of this disease remain unclear, the over-expression of the Galectins 3 and 9 in ectopic endometrial tissues suggests a role in the development and maintenance of the condition. Monoclonal antibodies (mAbs) are highly specific proteins with potential as diagnostic or treatment tools. The goal of this study is to generate antibodies against Gal3 and Gal9. …

Chemical Variability In The Unregulated Opioid Supply In The South Bronx, Yeireline Rodriguez

Student Theses

The unregulated drug supply in the United States has become increasingly unpredictable, contributing to persistently high overdose mortality, particularly in structurally marginalized communities such as the South Bronx. While drug adulteration has long been present in illicit markets, the number and pharmacological diversity of adulterants remained limited for much of the twentieth century. Over the past decade, however, the drug supply has undergone a significant transformation marked by the proliferation of potent synthetic opioids such as fentanyl and its analogues, frequently combined with novel sedatives and chemically diverse adulterants. These shifts have introduced increasing chemical complexity into the street drug …

Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith

Honors Theses

Antibiotic resistance is a growing threat to public health. Due to the overuse of antibiotics in agriculture, the overprescription of antibiotics, and the misuse of antibiotics by patients, antibiotic resistance is spreading at an alarming rate. As antibiotic resistance spreads, the antibiotics we depend on to treat common infections become ineffective. Therefore, it is imperative to develop novel treatments for infections that do not increase the prevalence of antibiotic resistance. One treatment being explored is the use of synthetic polymers with antibacterial properties. Synthetic polymers are advantageous because they can be synthesized from widely available precursors and their structure is …

Optimizing Itpa R178c Assays Via Hplc, Jared J. Reisnouer, Wally D. Pines

2026 Symposium

Two of the major nucleotide bases in DNA and RNA (Adenine and Guanine) are derived from the purine Inosine Monophosphate (IMP). IMP may occasionally form the noncanonical nucleotide Inosine Triphosphate (ITP) within the cell and become incorporated into DNA during replication, leading to potentially lethal errors. To combat this, human cells produce the “housekeeping” enzyme Inosine Triphosphatase (ITPA) to revert ITP to IMP. A mutation of this protein that replaces the 178th amino acid Arginine with Cysteine (R178C) is associated with a fatal infantile encephalopathy. Previous assessments of enzyme-substrate binding and catalysis for ITPA variants have been run at a …

Discovering Drug-Like Compounds By Targeting Protein-Protein Interactions Using A Yeast-3-Hybrid System, Chesley C. Blake

Senior Theses

Protein-protein interactions are important targets in cancer biology as they can make historically “undruggable” proteins viable drug targets. However, the current approach to targeting protein-protein interactions relies on the use of small molecule drugs, which have low efficiencies as they must cover a large surface area of the interaction. Further, traditional drug therapies often lead to off-target toxicity, limiting therapeutic specificity. The objective of this project is to develop a selection system in yeast to identify short peptide sequences that can disrupt protein-protein interactions specific to cancer cells. Following proof of principle and development of the AH109 yeast strain having …

Makara Journal of Science

Cancer is one of the deadliest diseases nowadays, and tyrosine kinase receptors play crucial roles in cancer cell survival, differentiation, proliferation, and migration. This study designed and developed a new inhibitor from heterocyclic-based xanthone derivatives to target two tyrosine kinase receptors, epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor (PDGFR), through in silico screening. Eighteen heterocyclic-based xanthones were evaluated through molecular docking for both receptors. All heterocyclic-based xanthones gave the root mean square deviation (RMSD) value lower than 2.00 Å. Xanthone with isobenzothiazole substituent (iBzThio) was found as the most potent inhibitor with binding energies of -10.60 and …

Rare Event: Neonatal Anaphylaxis Following Hepatitis B Vaccination – A Case Series From A Tertiary Care Center In India, Aarthi Ma, Revanth R

Advances in Clinical Medical Research and Healthcare Delivery

We report two cases of anaphylaxis following Hepatitis B vaccination in one-day-old neonates at a tertiary care hospital in India. Both cases presented with similar patterns of cutaneous reactions and respiratory symptoms shortly after intramuscular administration of the Hepatitis B vaccine. To our knowledge, this is among the few documented case series of neonatal anaphylaxis post–Hepatitis B vaccination, underscoring its rarity yet clinical importance. The cases highlight the critical importance of vigilant post-vaccination monitoring and prompt recognition of vaccine-associated adverse events in neonates. This report reviews current literature on anaphylaxis following vaccination and discusses optimal management strategies.

BACKGROUND: Kratom use is rising, increasing the need for safety and tolerability studies of high-quality and well-characterized kratom products in humans. Kratom's risk-benefit ratio, recommended dose, treatment-emergent adverse events (TEAEs), abuse potential, and withdrawal require evaluation. Thus, the safety and tolerability of 4 escalating single and 15 daily dried kratom leaf powder doses in human volunteers were evaluated over 47 days in the largest controlled kratom-administration study to date.

METHODS: A randomized, between-subject, double-blind, placebo-controlled, dose-escalation study of MitraLeaf kratom powder after single doses (SD), during 15 daily doses (multiple doses; MD), and a 23-day follow-up was conducted in 116 …

Antagonistic Effects Of Glucagon And Insulin On 5-Fluorouracil Efficacy In Colorectal Cancer, Gabriel M. Randolph, Andrea Florian

SPARK Symposium Presentations

Prior research on the combined effects of insulin and glucagon with low-dose chemotherapy in cancer treatment has yielded contradictory conclusions. Insulin potentiation therapy (IPT), a longstanding but understudied approach, is broadly claimed to enhance chemotherapeutic efficacy; however, it has also been characterized as pseudoscience lacking physiological merit. Adding further complexity, glucagon, insulin's antagonist hormone, has been shown to produce anti-cancer effects when combined with chemotherapeutic agents. The present study aims to observe the individual effects of both hormones on colorectal cancer cells in combination with 5-Fluorouracil (5-FU), to clarify their respective roles in combination therapy. Through the modulation of both …

Chemotherapy agents such as 5-Fluorouracil and Oxaliplatin are commonly employed in the management of various types of cancer. However, they have been implicated as causative factors of various side effects related to the heart. Drug-induced cardiotoxicity in rapid preclinical models could be employed as an effective tool for the identification of adverse effects. Daphnia magna is a small aquatic organism that is frequently employed in toxicological tests due to its transparent body that allows direct observation of physiological activities such as heart rates.

The purpose of the study was to evaluate the effect of various concentrations of 5-Fluorouracil and Oxaliplatin …

Perinatal Inflammation And Oxidative Stress Alter Adult Rat (Rattus Norvegicus) Motor Behavior, Alexander Young

Honors College Theses

Recent evidence in comparative animal models suggests that early life exposure to elevated inflammation (via LPS exposure) and oxidative stress (via acetaminophen exposure) may synergistically interact to alter typical neurodevelopmental trajectories, resulting in lasting effects on both behavior and gut-brain neurochemistry. The current study observed emotional and motor behaviors and collected fecal-boli to measure Tyrosine (TE) levels in male and female Long-Evans (Rattus norvegicus) rats. Subjects were either treated with [1] saline [2] lipopolysaccharide (LPS) to introduce an inflammatory state, [3] acetaminophen (APAP) to introduce oxidative stress, or [4] a dual-hit of both LPS + APAP on postnatal day (PD) …

Effects Of Dietary Perfluorobutane Sulfonate (Pfbs) On Adipose Tissue, Hannah Olofintuyi, Eric Gato

Honors College Theses

Per- and polyfluoroalkyl substances (PFAS) are chemical substances used in a variety of industrial applications and consumer products. Perfluorobutane sulfonate (PFBS) is often used as a replacement for the more harmful (Perfluoroalkyl sulfonate) PFAS chemicals that have been around longer. It is believed that PFBS does not remain in the body as long as other PFAS compounds; however, there is a rising concern that it has the potential to cause damage to human health. This study focused on understanding how dietary PFBS exposure affects metabolism-related processes in adipose tissues in rats. To accomplish study objectives, Sprague Dawley rats were exposed …

Dose-Dependent Developmental Toxicity Of Cisplatin In Zebrafish Embryos, Reagan D. Sellers, Katherine T. Doucet, Jinhee Park, Andrea Florian

SPARK Symposium Presentations

Cisplatin is a widely used chemotherapy drug for treating various types of cancer. Although cisplatin is effective in killing cancer, it can also cause toxic side effects in normal tissues. Because cisplatin can cross the placental barrier, its use during pregnancy is generally avoided, particularly during early embryonic stages of fetal development. Exposure to cytotoxic drugs during embryogenesis may lead to developmental abnormalities, birth defects, or pregnancy complications. Understanding how cisplatin affects early development is therefore important.          
       Zebrafish (Danio rerio) are an established model for studying developmental toxicity due to their rapid external development, transparent embryos, and genetic similarity to …

Exploring Anticholinergic Neurotoxicity: Diphenhydramine's Impact On Neuro-2a Cell Morphology, Expression, And Viability, Jordan B. Mcintyre

Honors Undergraduate Theses

Anticholinergic medications, such as diphenhydramine (commonly known as Benadryl), are increasingly recognized for their association with cognitive impairment and neurodegenerative disease. These medications, which inhibit the action of acetylcholine, a neurotransmitter essential for the formation and utilization of the central and peripheral nervous system, have been implicated in conditions such as dementia and may impact fundamental cellular processes like neurogenesis and cell proliferation. This study investigates the effects of diphenhydramine on neurogenesis when introduced to Neuro-2a cells during differentiation. For all studies cells were plated on coverslips or in 6-well plates with differentiation media containing 0 ng/mL, 50 ng/mL, …

Investigating The Efficacy Of Mebendazole On C. Elegans: Implications For Anthelmintic Drug Development, Brooke Brewer, Saja Al-Saweily

Student Scholar Symposium

About 1.5 billion people in the world are infected with soil-transmitted helminths, especially those who live in high poverty areas. These infections affect communities with poor access to clean water, sanitation and hygiene in tropical and subtropical areas, keeping them in a state of poverty. Our research focuses on drugs that target the parasitic worms currently approved by the World Health Organization (WHO). The WHO currently only has 4 approved drugs for Mass Drug Administration, due to low profit margins, complex parasite life cycles, and rising drug resistance (World Health Organization 2023). While Mebendazole is effective against many common parasitic …
