Evaluation Of Avenanthramide-A As A Skin Penetration Enhancer: In Vitro And In Vivo Testing On Permeation Of Magnesium Ascorbyl Phosphate And Diclofenac Sodium From Topical Gels, Darshil Dhiren Shah

Selected Full-Text Dissertations 2020-

Topical and transdermal drug delivery are favored to deliver active pharmaceutical ingredients directly to the skin as an alternative to oral administration for systemic effects. In either case, the active molecules must cross the stratum corneum and epidermis to reach the site of action. The stratum corneum serves as a primary barrier limiting compounds from fully penetrating the skin. Therefore, it is necessary to add penetration enhancers to topical formulations to enhance drug delivery through the skin. Often, penetration enhancers are also irritant to the skin. Earlier research in our pharmaceutical laboratory showed that an addition of colloidal oatmeal, produced …

A Review Of Praziquantel Resistance In Schistosomes And The Future Of Schistosomiasis Control, Gabriela G. Eastham

Senior Honors Theses

Schistosomiasis is a group of both acute and chronic parasitic trematode infections of the genus Schistosoma. Praziquantel (PZQ) has been the drug of choice to treat schistosomiasis for decades. Though it is effective against all three clinically relevant species, heavy reliance on PZQ has led to concerns of schistosome resistance, especially in areas that have implemented this drug in mass drug administration (MDA) programs. Although there is currently insufficient evidence to conclude that schistosomes are becoming resistant to PZQ on a large scale, other control methods are a necessity to best treat and eliminate schistosomiasis. This article summarizes the …

The Impact Of Cocaine On Inflammatory Markers In Sim-A9 Microglial Cells, Tyler Vaglivelo

Honors Scholar Theses

Substance use disorders are conditions in which an individual continues to use a drug or other substance despite adverse consequences to their health and well-being. It has been hypothesized that inflammation within the central nervous system plays a critical role in the development of substance use disorders. The resident macrophages in the brain, also known as microglia, release markers of inflammation in response to injury or infection. A better understanding of the inflammatory response mediated by microglia in response to drugs of misuse can validate this hypothesis and help guide drug development. In the current studies, the microglia cell line …

Combined Inhibition Of Lysine-Specific Demethylase 1 And Kinase Signaling As A Preclinical Treatment Strategy In Glioblastoma, Lea Stitzlein

Dissertations and Theses (Open Access)

Glioblastoma is the most common primary malignant brain tumor in adults, with limited treatment options resulting in a poor prognosis. Lysine-specific demethylase 1 (LSD1) is overexpressed in glioblastoma and contributes to tumor growth and treatment resistance. Inhibitors of LSD1 have shown preclinical promise but have had limited clinical development for glioblastoma. Given the frequent kinase pathway alterations in glioblastoma, the interplay between LSD1 inhibition and kinase signaling pathways was investigated to identify vulnerabilities that could be exploited through rationally designed combination therapies. We hypothesized that LSD1 inhibitors would activate kinase signaling pathways, such as MAPK, and the addition of kinase …

Advancing Drug-Drug Interaction Prediction Using Multi-Modal Feature Integration With Graph Neural Networks, Ernest C. Chianumba

Theses, Dissertations and Culminating Projects

Pharmaceutical treatments are essential for managing medical conditions, but drug-drug interactions (DDIs) pose significant risks to patient safety and healthcare outcomes. This research integrates Knowledge Graphs and Graph Neural Networks to predict DDIs by exploring complex drug relationships. We construct a comprehensive knowledge graph using DrugBank data (1,000 drugs, 155,774 interactions) enriched with molecular features from PubChem. Our methodology introduces a novel multi-modal approach by integrating transformer-based embeddings (ChemBERTa, SPECTER, and SBERT) to create 1152-dimensional feature vectors that capture structural, biomedical literature, and semantic properties of drugs. Formulating DDI prediction as a link prediction task, we compare three Graph Neural …

Machine Learning And Protein Engineering Approaches To Understanding Kinesin-5 Activity, Jason Eden Sanchez

Open Access Theses & Dissertations

Cancer is a term describing a collection of diseases that result in uncontrolled cell growth. Cancer has manifold etiologies and underlying cancers are rouge biochemical pathways involving many different proteins. In the current work, two approaches are used to enhance knowledge of kinesin-5, a potential cancer target involved in cell division. Kinesin-5 promotes cell division by cross-linking and separating microtubules in dividing cells. The first approach uses machine learning (ML) to identify small molecule inhibitors for kinesin-5. Though decades of research have uncovered classes of small-molecules which inhibit kinesin-5 in vitro and in vivo, no candidates have reached phase III …

The Effect Of Cellular Glucose Levels On Inotersen-Mediated Target Reduction In In Vitro Cell Models, Andrea Durwin

Honors Scholar Theses

Antisense oligonucleotide (ASO) drugs are a new therapeutic modality to treat rare as well as common diseases. These drugs work to reduce disease by targeting the mRNA of the gene that causes the disease, therefore limiting the proteins that further propagate the signs and symptoms of the disorder. Many people who suffer from more severe diseases, such as Alzheimer’s, Parkinson’s, Duchenne Muscular Dystrophy (DMD), and a wide array of cancers, utilize ASO drugs for treatment, but the drug is also used with those suffering from more common diseases such as diabetes. The efficacy of ASO drugs to silence their mRNA …

Determining The Bioaccumulation Of Minor Cannabinoids In Zebrafish Larvae, Kamdyn A. Holt

Honors Theses

Due to the increasing prevalence of cannabis product availability and usage in the modern United States, particularly among pregnant individuals, evaluating the bioaccumulation of minor cannabinoids to further understand the adverse effects of cannabinoids during early development is critical. This study quantitated the uptake of eight minor cannabinoids ((∆8-tetrahydrocannabinol (∆8-THC), ∆9-THC, ∆10-THC, cannabidiol (CBD), cannabigerol (CBG), cannabinol (CBN), tetrahydrocannabivarin (THCV), and hexahydrocannabinol (HHC)) in zebrafish larvae following water-borne 2 µM exposures from 6 to 96 hours post fertilization (hpf). Larvae were homogenized at 96 hpf and analyzed using a gas chromatography- mass spectrometry (GC-MS) method developed in this study. Bioconcentration …

Fluorescent Labeling And Size-Dependent Uptake Of Mesoporous Silica Nanoparticles In Ovarian Cancer Tumor Spheroids, Kimberly R. Berardis

Honors Scholar Theses

Ovarian cancer is the most lethal gynecologic malignancy, with most patients presenting at an advanced stage. While surgical debulking improves survival, nonresectable tumors (<1 cm) contribute significantly to morbidity and remain difficult to treat. Nanocarrier-based drug delivery systems offer an innovative approach to targeted therapy and palliation. In vivo models have demonstrated that intraperitoneally delivered mesoporous silica nanoparticles (MSNs) preferentially accumulate in tumors with low systemic exposure, enabling targeted chemo- and radiotherapy.

MSNs are particularly suited for radiotherapeutic delivery, as their strong interactions with tumor extracellular matrices drive selective uptake. Additionally, they exhibit excellent stability under neutron flux, allowing for loading with stable isotopes and irradiation immediately prior to administration. High radionuclide retention after dilution further minimizes systemic exposure and toxicity.

A key …

Studies To Understand The Stability And Liabilities Of Legumain-Cleavable Antibody-Drug Conjugates, Michele Yi

Undergraduate Honors Theses

Antibody-drug conjugates (ADCs) offer targeted drug delivery of potent cytotoxic payloads, minimizing systemic toxicity. However, the stability of the linker is integral to ensure that there is minimal off-target payload release and little systemic toxicity. This study analyzes the physical and biological stability of our new legumain-cleavable vs traditional cathepsin-cleavable antibody-drug conjugates (ADCs), with a focus on hydrophobicity, thermal stability, aggregation, and biological payload release. Our findings indicate that decreased hydrophobicity of the legumain-cleavable ADCs compared to cathepsin-cleavable ADCs is correlated with decreased aggregation (predicting lower uptake by liver macrophages and therefore slower clearance and less systemic toxicity) and lower …

Targeting GTFs has emerged as a promising strategy for preventing dental caries, with previous studies demonstrating its potential efficacy. This study builds on our prior work by providing detailed molecular insights into the binding modes of previously identified GTF inhibitors. Using computational tools, including density functional theory, molecular docking, and molecular dynamics simulations, we examined the binding …

Advancing A Patient- And Carer-Centered Approach For The Clinical Development Of New Therapeutics For Aneurysmal Subarachnoid Hemorrhage: Insights From A Qualitative Study, Sonya Abraham, Silvia Amaro, Ellyn Getz, Sylvia Herget, Gregory J. Kato

Journal of Patient-Centered Research and Reviews

Aneurysmal subarachnoid hemorrhage (aSAH) is characterized by a high rate of fatality and high risk of secondary brain injury. More treatment options are needed to improve outcomes. There are very few reports in the medical literature involving patient experience of aSAH, which is known for its unexpected onset and profound medical impact. Improved understanding of this patient experience would help make future clinical research more patient centered. To this end, we convened an advisory board consisting of aSAH patients and care partners in the United States. Participants emphasized the critical role that care partners play during hospitalization and in accessing …
