Hypoxia Regulates Vessel-Modifying Macrophages And Vice Versa In Tumors, Kayla Jo Steinberger
Hypoxia Regulates Vessel-Modifying Macrophages And Vice Versa In Tumors, Kayla Jo Steinberger
Graduate Theses, Dissertations, and Problem Reports
Hypoxia, or low oxygen, is a common feature of solid tumors correlating with poor survival in cancer patients. Growing tumors need a blood supply to deliver oxygen. Tumors attempt to re-acquire oxygen by forming new blood vessels from nearby, pre-existing vessels, a process known as angiogenesis. Past treatments aimed at preventing this process yielded not only disappointing results in the clinic but sometimes worsened the patient’s prognosis making the tumor more hypoxic, emphasizing the urgent need for novel targets. In tumors, angiogenesis is notoriously dysfunctional resulting in leaky, under-perfused blood vessels which cannot adequately deliver oxygen and exacerbates hypoxia. Emerging …
Influence Of Maternal Nano-Titanium Dioxide Inhalation Exposure On Cyclooxygenase Metabolites: Maternal Microvascular And Sexually Dimorphic Feto-Placental Outcomes., Julie Anne Griffith
Influence Of Maternal Nano-Titanium Dioxide Inhalation Exposure On Cyclooxygenase Metabolites: Maternal Microvascular And Sexually Dimorphic Feto-Placental Outcomes., Julie Anne Griffith
Graduate Theses, Dissertations, and Problem Reports
Nano-titanium dioxide (nano-TiO2) is an engineered nanomaterial (ENM), which is widely utilized in diverse products like surface coatings, cosmetics, medical devices, and filters. Inhaled nano-TiO2 has been demonstrated to induce pulmonary inflammation, impair microvascular function, and hinder generational reproductive endpoints. These outcomes indicate why it is important to explore gestation, as it requires timely vascular adaptations to support maternal and fetal health and development. Therefore, the central hypothesis of my dissertation is: maternal nano-TiO2 inhalation exposure will impact maternal microvascular function and fetoplacental hemodynamics and function in a sexually dimorphic manner.

Il-27 Negatively Impacts Immunity Developed Following Bcg Administration, Shelby D. Bradford
Graduate Theses, Dissertations, and Problem Reports
Mycobacterium tuberculosis (Mtb) is the causative agent of tuberculosis (TB), a predominantly respiratory pathogen responsible for over ten million infections and one million deaths last year. Despite it being a primary objective of the World Health Organization (WHO) for several decades to irradicate TB, progress toward this objective has fallen short of the 2020 target to end TB by 2035. Meeting this goal will require advancements in diagnostic tools, education, healthcare access, and treatments and preventatives. Regarding prevention, the primary tool for this strategy is through vaccination. Currently, the only licensed vaccine for protection against TB is the century old …

Advancing Medical Technology For Motor Impairment Rehabilitation: Tools, Protocols, And Devices, Matthew Yough
Graduate Theses, Dissertations, and Problem Reports
Excellent motor control skills are necessary to live a high-quality life. Activities such as walking, getting dressed, and feeding yourself may seem mundane, but injuries to the neuromuscular system can render these tasks difficult or even impossible to accomplish without assistance. Statistics indicate that well over 100 million people are affected by diseases or injuries, such as stroke, Parkinson’s Disease, Multiple Sclerosis, Cerebral Palsy, peripheral nerve injury, spinal cord injury, and amputation, that negatively impact their motor abilities. This wide array of injuries presents a challenge to the medical field as optimal treatment paradigms are often difficult to implement due …
Longitudinal Oxygen Imaging In 3d (Bio)Printed Models, Ryan Curtis O'Connell
Longitudinal Oxygen Imaging In 3d (Bio)Printed Models, Ryan Curtis O'Connell
Graduate Theses, Dissertations, and Problem Reports
Electron paramagnetic resonance (EPR), and its molecular imaging modality, is a powerful tool to noninvasively map various biological and chemical markers within objects of interest. Reliable data acquisition is a major impeding factor for longitudinal hands-off measurements. Measurements are especially challenging in biomedical applications, as live objects are not static. Frequent changes occur that require constant fine recalibration of the EPR detection system, called the resonator. To enable longitudinal imaging, a technology permitting automatic digital control of resonator coupling, tuning, and EPR data acquisition was developed. Automation was achieved through the utilization of a microcontroller and digital peripheral components such …

Development And Characterization Of Monoclonal Antibodies Against Pseudomonas Aeruginosa, Jason Kang
Graduate Theses, Dissertations, and Problem Reports
Antimicrobial resistance (AMR) has emerged as a global crisis, posing significant challenges to the treatment and management of infectious diseases. The escalating prevalence of antibiotic-resistant bacteria has made many antimicrobial therapies ineffective, necessitating the development of alternative strategies to combat microbial infections. The rise of multidrug-resistant pathogens, such as Pseudomonas aeruginosa and Serratia marcescens, further exacerbates this problem, as these pathogens exhibit high levels of resistance to multiple antibiotics and cause severe infections in vulnerable populations. In response to the need for alternative therapeutic approaches, monoclonal antibodies (mAbs) have emerged as promising candidates for combating AMR. In this work, we …
