Investigating And Targeting Iron Metabolism In Pseudomonas Aeruginosa And Klebsiella Pneumoniae, Zachary Scott

Theses & Dissertations

Antimicrobial resistance is an incredibly pressing issue in modern medicine. Because of that many researchers are pursuing just as many avenues for treatment of these pathogens. However, due to the nature of bacteria many of these methods are stop gaps and the bacteria can develop typically within years of their deployment. Therefore, more robust methods of treating infections of antimicrobial resistant bacteria that are difficult or impossible to develop resistance to are required. To produce this effect the treatment would need to target and alter or inhibit functions or structures essential to the bacteria that could not be altered, additionally …

Examining Caf Heterogeneity In Pancreatic Cancer, Nidhi V. Dwivedi

Theses & Dissertations

This thesis delves into the complexities of pancreatic ductal adenocarcinoma (PDAC) and its microenvironment. This study centers on unraveling the heterogeneity of pancreatic cancer-associated fibroblasts (CAFs) using a panel of patient-derived pancreatic fibroblasts. Additionally, it delves into the realm of G-protein-coupled receptors (GPCRs), with a specific emphasis on the Endothelin receptors (ETAR and ETBR), all within the context of PDAC.

A key achievement is the development of immortalized patient-derived pancreatic fibroblasts (iPDPFs), replicating CAF heterogeneity in PDAC. The iPDPFs were able to recapitulate the PDAC CAF heterogeneity, plasticity, and the overlapping nature of the tumor stroma. Functional characterization of iPDPFs …

Towards A Mode Of Action For The Anti-Schistosomal Aryl Hydantoins, Thomas Schulze

Theses & Dissertations

Schistosomiasis is a significant human disease caused by the helminth parasite Schistosoma mansoni. Praziquantel remains the only clinically used treatment, yet it is rapidly metabolized and only effective against the adult stage worm infection. Ro 13-3978 (AR02) is a potent antischistosomal compound with activity against multiple S. mansoni life stages; however, it manifests anti-androgenic activity. Additionally, the mechanism of action for worm clearance remains unknown. The structure of Ro 13-3979 was used to generate optimized derivatives, including AR102, that show increased potency towards worms, reduced off-target anti-androgen effects, and extended half-life thereby increasing the feasibility for a single-dose curative treatment. …

Synergetic Signaling Between The Chlamydia Secreted Effectors Tarp And Tmea Regulates Actin Kinetics And Efficient Entry, Matthew Romero

Theses & Dissertations

Chlamydia trachomatis is both the leading cause of non-congenital preventable blindness in developing nations and the leading source of bacterial sexually transmitted infections. As an obligate intracellular pathogen, Chlamydia has an absolute requirement on gaining entry into its host, which is accomplished by manipulating the host actin cytoskeleton to assemble engulfment structures that drive pathogen entry. In support of this, Chlamydia secretes the effectors TarP and TmeA via a type-III secretion system, whose respective signaling outputs operate synergistically to generate rapid actin kinetics and efficient pathogen engulfment. Rapid actin recruitment characteristic of invading Chlamydia is derived from a collaborative interaction …

Understanding The Relationship Between Narcissism And Political Orientations In College-Aged Adults, Sabrina Richards

Undergraduate Honors Theses

When you try to guess someone’s political beliefs, you probably look towards the usual culprits: race, gender, education, religion, age, marital status, and more. Have you ever tried looking at their narcissistic tendencies? There are seven different types of narcissism, and in a study conducted by Peter K. Hatemi and Zoltan Fazekas in 2018, it was revealed that there is a relationship between an adult’s narcissistic personality traits and their political orientations. It was observed that entitlement narcissism is associated with more conservative political orientations, while exhibitionism narcissism is associated with more liberal political orientations. However, there is a lack …

Tipping The Mesoscales: Advances In Multipeak Bragg Coherent Diffraction Imaging, J. Nicholas Porter

Theses and Dissertations

Material failure begins with strain between atoms and cascades upward into macroscopic damage such as cracks. Therefore, our ability to predict (and therefore prevent) material failure is largely limited by our understanding of this process. This understanding, however, has been impeded by the difficulty of directly observing such phenomena. In this thesis, I discuss recent advances in Bragg coherent diffraction imaging (BCDI) which produce three-dimensional, mesoscopic images of interior strain in microcrystals. In particular, I present a novel algorithm, based on the concept of cyclic-constrained optimization (CCO), for the rapid, coupled reconstruction of a microcrystal from multiple Bragg diffraction patterns. …

Pkcε Activator Protects Hippocampal Microvascular Disruption And Memory Defect In 3×Tg-Alzheimer's Disease Mice With Cerebral Microinfarcts, Huaixing Wang, Zongxiu Zhang, Jarin Hongpaisan

Center for Translational Medicine Faculty Papers

BACKGROUND: Current evidence suggests that microvessel disease is involved in Alzheimer's disease (AD). Cerebrovascular disease correlates with cardiovascular disease and is complicated in ≈40% of AD patients. The protein kinase C (PKC) ε activator DCPLA can stimulate human antigen (Hu) R that prevents degradation and promotes the translation of mitochondrial Mn-superoxide dismutase (MnSOD) and vascular endothelial growth factor-A (VEGF) mRNAs.

METHODS: To induce brain microinfarcts, we injected triple transgenic (3×Tg) and wild-type (WT) control mice with microbeads (20 μm caliber) into common carotid arteries, with or without the DCPLA-ME (methyl-ester) for 2 weeks. After water maze training, mice at 16 …

Acidosis-Mediated Increase In Ifn-Γ-Induced Pd-L1 Expression On Cancer Cells As An Immune Escape Mechanism In Solid Tumors, Philipp Knopf, Dimitri Stowbur, Sabrina H L Hoffmann, Natalie Hermann, Andreas Maurer, Valentina Bucher, Marilena Poxleitner, Bredi Tako, Dominik Sonanini, Balaji Krishnamachary, Sanhita Sinharay, Birgit Fehrenbacher, Irene Gonzalez-Menendez, Felix Reckmann, David Bomze, Lukas Flatz, Daniela Kramer, Martin Schaller, Stephan Forchhammer, Zaver M Bhujwalla, Leticia Quintanilla-Martinez, Klaus Schulze-Osthoff, Mark D Pagel, Marieke F Fransen, Martin Röcken, André F Martins, Bernd J Pichler, Kamran Ghoreschi, Manfred Kneilling

Faculty, Staff and Student Publications

Immune checkpoint inhibitors have revolutionized cancer therapy, yet the efficacy of these treatments is often limited by the heterogeneous and hypoxic tumor microenvironment (TME) of solid tumors. In the TME, programmed death-ligand 1 (PD-L1) expression on cancer cells is mainly regulated by Interferon-gamma (IFN-γ), which induces T cell exhaustion and enables tumor immune evasion. In this study, we demonstrate that acidosis, a common characteristic of solid tumors, significantly increases IFN-γ-induced PD-L1 expression on aggressive cancer cells, thus promoting immune escape. Using preclinical models, we found that acidosis enhances the genomic expression and phosphorylation of signal transducer and activator of transcription …

Beyond Whiteness: Revisiting Jews In Ethnic America, Jonathan Karp

The Jewish Role in American Life: An Annual Review

The concept of ethnicity, once in vogue, has largely gone out of fashion among twenty-first-century social scientists, now replaced by models of assimilation defined in terms of the construction of whiteness and white supremacy. Beyond Whiteness: Revisiting Jews in Ethnic America explores the benefits of reconfiguring the ethnic concept as a tool to analyze the experiences of twentieth-century American Jews—not only in relation to other “white” groups of European descent, but also African Americans and Asian Americans, among others. The essays presented here, ranging from comparative studies of Jews and Asians as “model minorities” to the examination of postethnic “Jews …

Understanding The Psychological Significance Of Astrology In Millennial Women's Lives, Rachel June Floyd

Electronic Theses and Dissertations

In North America, astrology has been experiencing a resurgence in popularity. This is immediately remarkable given that the United States and Canada are industrialized, modern societies where astrology is widely lamented as a pseudoscience. This dissertation presents a phenomenological exploration of the underlying reasons for this cultural trend, particularly among the demographic that uses it most: millennial women. Existing psychological literature on astrology is primarily dominated by correlational studies or historical analyses and lacks the depth and richness of direct experiences of individuals engaging with this phenomenon. This study sought to address this gap within psychological literature specifically, by conducting …
