Terahertz Electromagnetic Effects And Chirality-Induced Spin Selectivity In Dna, F. Matthew Mihelic Md

Faculty Publications

The effects of terahertz electromagnetic stimulation of the DNA molecule can be understood through modeling of the quantum logical mechanics of the DNA molecule.  Coherent conduction of electron spin states along the aromatic nucleotide base pairs and chirality-induced spin selectivity are two characteristics of the DNA molecule that are involved in the precise separation of the double-stranded DNA molecule at a specific location.  Such modeling can inform predictions of DNA strand separation and has significant implications for understanding DNA transcription bubble formation.

Retrospective Comparison Of Prostate Vmat Boost Plans With Central Versus Offset Isocenter Placement, Carly Shefffield

Masters Projects

This retrospective study evaluated the effects of isocenter placement on dosimetric outcomes for sequential prostate boost planning using volumetric modulated arc therapy (VMAT). Ten patients previously treated with whole pelvis radiation therapy (WPRT) followed by a sequential boost were selected. For each patient, two VMAT boost plans were created using identical planning objectives and beam arrangements. One plan was optimized using the original WPRT isocenter, while the second plan had the isocenter placed at the center of the boost planning target volume (PTV). Target coverage, conformity, and organ-at-risk (OAR) dose metrics were compared between the two planning techniques. Both plans …

Impact Of Anatomical Changes On Treatment Plan Robustness: A Comparative Study Of Intensity Modulated Proton Therapy And Volumetric Modulated Arc Therapy In Head And Neck Cancer., Jennifer Croft

Masters Projects

Head and neck cancer patients often experience anatomical changes during radiation therapy, including weight loss and tumor regression. These changes can alter planned dose distribution and affect treatment accuracy. Based on the previous understanding, IMPT offers highly conformal dose delivery but is sensitive to the patient’s geometry changes and daily setup uncertainties, while VMAT may provide greater stability under these uncertainties. However, as of today, there is no quantitative analysis and comparison between the two modalities using real clinical data. The purpose of this study is to compare the robustness of IMPT and VMAT for head and neck cancer by …

Characterization Of Circulating Extracellular Proteome In Plasma Samples Of Triple-Negative Breast Cancer Patients, Brionna Wilson

Honors Theses

Extracellular vesicles (EVs) are membrane-bound vesicles secreted by cells in the body that play an important role in intercellular signaling, immune modulation, and transfer of biomolecules between cells. EV s reflect the physiological state of their cells of origin, so they are being explored as potential noninvasive biomarkers for cancer detection and monitoring. Triple-negative breast cancer (TNBC), an aggressive subtype lacking targeted therapies, is difficult to detect early and currently has no reliable prognostic biomarkers. This study aimed to quantify EV concentrations in the blood serum of TNBC patients (n=40) compared with cancer-free healthy controls (n=35) as well as determine …

Analyzer-Less X-Ray Interferometry With Super-Resolution Methods, Murtuza S. Taqi

LSU Master's Theses

X-ray interferometry provides valuable information on attenuation, small-angle scattering, and differential phase contrast. This multi-modal contrast can aid in many clinical applications, such as lung diseases and breast cancer. However, standard inter- ferometry has an analyzer grating that can increase the dose requirement to maintain the same image quality as a standard X-ray. We propose the use of super-resolution methods for X-ray grating interferometry without an analyzer, with detectors that fail to meet the Nyquist sampling rate needed for traditional image recovery algorithms. Detector phase- steps are used to nominally recover the sampling and iteratively recover the visibility and the …

The Effects Of Body Mass Index On Fertility And In Vitro Fertilization, Morgan R. Kidd

Honors College Theses

In-vitro fertilization (IVF) is the most widely used type of assisted reproductive technology for treating infertility arising from a number of conditions. As obesity rates continue to climb in the United States, infertility has been discovered to have a direct correlation. Individuals that fall below or above the healthy body mass index range are found to have disrupted regulation of the hypothalamic-pituitary-gonadal axis, resulting in diminished reproductive health. Those that are diagnosed as infertile due to conditions caused by the effects of low body mass index or high body mass index may seek assisted reproductive technologies to intervene in achieving …

Unlocking Hope: Mirtazapine's Promise In Obsessive-Compulsive Disorder Treatment, Rebecca K. Hicks, Iram Kingson, Jordan Gaal, Suzanne Holroyd

Marshall Journal of Medicine

Obsessive-compulsive disorder (OCD) is a chronic and debilitating psychiatric condition characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions). While selective serotonin reuptake inhibitors (SSRIs) and cognitive-behavioral therapy (CBT) are first-line treatments for OCD, a significant proportion of patients remain refractory to these interventions. Mirtazapine, an atypical antidepressant with unique pharmacological properties, has emerged as a potential adjunctive therapy for treatment-resistant OCD. This review synthesizes existing evidence regarding the efficacy and safety profile of mirtazapine in OCD management. We analyze clinical trials, observational studies, and case reports, distinguishing high- vs. low-quality evidence, and discuss mechanisms underlying mirtazapine's therapeutic effects. Additionally, …

The Efficacy Of Cgrp Antagonists Versus Other Non-Migraine Specific Medications As Prophylactic Treatment For Episodic And Chronic Migraine, Lauryn C. Hutto

The PA Department Journal of Medical Science

Introduction: Migraines are a disabling neurological condition affecting 12-15% of the population. Migraines are characterized by a unilateral throbbing headache lasting between 4 and 72 hours, often accompanied by photophobia, phonophobia, nausea, or vomiting. Until the approval of the first CGRP antagonist, Erenumab, in May 2018, the prophylactic treatment for migraines relied on non-migraine-specific medications, such as antihypertensives and antiepileptics. Studies have been done to determine the efficacy and safety of the new medications, but few have directly compared them to older non-migraine-specific medications used for prevention. The purpose of this paper is to compare the efficacy of CGRP …

Impact Of Senescence On Breast Cancer Outcomes, Gracie Sous

Honors Undergraduate Theses

Cellular senescence is a biological process in which damaged cells exit the cell cycle while remaining metabolically active and accumulating within tissues. Senescence plays a complex role in breast cancer progression, largely through the secretion of senescence-associated secretory phenotype (SASP) factors. These factors include a broad range of inflammatory cytokines, chemokines, and signaling molecules that can influence the tumor microenvironment.

Studies suggest that senescence may significantly promote cancer metastasis. Therefore, this study aims to investigate the genes involved in cancer progression and to improve understanding of how SASP is regulated, which is critical for improving breast cancer outcomes. The central …

Pioglitazone Uncouples Macrophage Inflammatory Signaling From Epithelial Oxidative Stress During Map Infection Mimicking Crohn’S Disease Treatment, Sabera Akter Bushra

Graduate Studies Theses and Dissertations 2026

Crohn’s disease (CD) is a chronic inflammatory bowel disease characterized by intestinal inflammation, epithelial barrier dysfunction, and abnormal immune signaling. CD pathophysiology is increasingly linked to Mycobacterium avium subspecies paratuberculosis (MAP) infection, which increases chronic macrophage activation and the production of inflammatory mediators that lead to epithelial damage. Among these mediators, CXCL10, TNF-α, and IL-6 contribute in inflammation, while NOX-1 and SERPINE-1 indicate epithelial oxidative stress and damage. Despite the role of macrophage-epithelial interaction in CD, selective pharmaceutical regulation of this axis remains unclear. Pioglitazone, an FDA-approved PPARγ agonist used for type 2 diabetes, is an appealing repurposing candidate, given …

Dual-Task Interaction Between Vestibular Function And Cognitive Processing Using The P300 Event-Related Potential, Laurel Elise Money-Nolan

Graduate Theses and Dissertations (2019 - present)

Previous research has established links between vestibular function and cognitive processing, aging and cognitive function, and aging and vestibular function.

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Adults' Intention To Take An Arthritis Prescription Drug Based On Drug Advertisements, Amanda Radola

Seton Hall University Dissertations and Theses (ETDs)

Direct-to-Consumer Prescription Advertising (DTCPA) has rapidly expanded, particularly via social media, but research on its influence on individual decisions regarding prescribed medications remains limited. This gap is notable among chronic disease patients, such as those with arthritis, which affected over 58.5 million U.S. adults as of 2015 and is projected to rise to 78.4 million by 2040 (Barbour et al., 2017; Hootman et al., 2016). Social media discussions show significant activity following television ads for arthritis drugs (Curtis et al., 2017). However, few studies explore how DTCPA impacts patient intentions to take advertised arthritis medications. This study employed a novel …
