Clinical And Environmental Factors Affecting The Survival Outcomes Among Stage 1a Tn0m0 First Primary Non-Small Cell Lung Carcinoma Patients In The United States., Naiya Patel
Electronic Theses and Dissertations
Background: Lung cancer is the second leading cause of death in the United States (U.S.). The most prevalent histological type of lung cancer is Non-Small Cell Lung Cancer (NSCLC), which has an overall five years survival of 5% if left untreated. Therefore, early treatment of NSCLC is vital to improve overall survival (OS) outcomes. Several factors affect survival outcomes, which can be categorized as modifiable or non-modifiable. The difference in timely receipt of guideline-concordant treatment affects the survival outcomes of patients with stage 1A NSCLC. This dissertation explored factors that affect treatment and survival outcomes among stage 1A NSCLC patients …
Species Data And Vector Modeling: Evaluating Datasets For Improved Models Of Ixodes Ricinus Tick Distribution In Europe Under A Changing Climate, Steven Jones
Electronic Theses and Dissertations
To increase capacity for monitoring and surveillance of tick-borne diseases, publicly available tick distribution and climate change datasets are required to create accurate predictive distribution models. It is difficult, however, to assess model accuracy and utility when using incomplete datasets. The more recent development of comprehensive tick databases for Europe and availability of climate change scenarios from multiple IPCC Assessment Reports allows for improved modeling efforts. Multiple tick datasets were combined and three climate change projections were compared by predicting current and future distributions of Ixodes ricinus ticks in Europe using the MaxEnt species distribution model. Overall, much of Europe …
The Impact Of Volatile Organic Compound Exposure On Subclinical Biomarkers Of Cardiovascular Injury., Breandon Taylor
The Impact Of Volatile Organic Compound Exposure On Subclinical Biomarkers Of Cardiovascular Injury., Breandon Taylor
Electronic Theses and Dissertations
Pollution has been identified as the leading environmental cause of non-communicable disease and premature deaths globally. Volatile organic compounds (VOCs) are gaseous chemical constituents of pollution derived from a variety of sources, including industrial solvents and byproducts, automobile exhaust, tobacco smoke, cleaning supplies, and personal care products. VOCs are also abundant at various Superfund and Hazardous Waste Sites. Emerging data suggest that VOC exposure is associated with several adverse health outcomes, including cardiovascular disease (CVD). VOCs and their metabolites can potentially damage the endothelial lining of blood vessels, resulting in perturbed vascular function and vascular inflammation. We hypothesize that VOC …
Protest-Related Tear Gas Exposure And Menstrual Function, Emily Kathleen (Steinmetz) Reece
Protest-Related Tear Gas Exposure And Menstrual Function, Emily Kathleen (Steinmetz) Reece
Electronic Theses and Dissertations
During the racial justice protests of 2020 and 2021, crowd control chemical irritants (referred to as “tear gas”) were deployed against protesters, after which there were anecdotal reports of altered menstrual cycles among exposed individuals. There is only one peer reviewed published study on tear gas exposure and menstrual health. This study examined whether tear gas exposure was associated with menstrual cycle outcomes among women attending the 2020-2021 protests. Data from 103 women who attended racial justice protests in 2020 and 2021 were collected through an online questionnaire. Data included protest attendance, acute symptoms of tear gas exposure, whether medical …
The Effects Of Polychlorinated Biphenyls Exposure On Non-Alcoholic Fatty Liver Disease : Role Of Aryl Hydrocarbon Receptor., Hongxue Shi
Electronic Theses and Dissertations
Polychlorinated biphenyls (PCBs) are detectable in serum of 100% of adults in US, and has been associated with fatty liver disease in epidemiological studies. PCBs are classified as either dioxin-like (DL) or non-dioxin-like (NDL) PCB based on their ability to activate the aryl hydrocarbon receptor (AhR). We used exposures that reflect human bioaccumulation patterns, which resembles Aroclor 1260 with a low level of the DL-PCB, PCB 126. Our aim was to determine if this exposure will activate the human and mouse AhR and examine if receptor activation influences these steatotic responses due to PCB exposures. DL-PCBs exposure-induced AhR activation in …
Air Pollution, Pulmonary Oxidative Stress, And The Endothelin System In The Development Of Cardiovascular Injury., Jordan B. Finch
Air Pollution, Pulmonary Oxidative Stress, And The Endothelin System In The Development Of Cardiovascular Injury., Jordan B. Finch
Electronic Theses and Dissertations
The goal of this project was to examine the role of endothelin-1 (ET-1) as a mediator in the pathway between air pollution exposure and the development of vascular injury. A human cohort and male mice (C57BL/6 and ecSOD-Tg) were used to evaluate changes in the ET-1 system in response to exposures of fine particulate matter (PM2.5). Human ET-1 levels were significantly associated with environmental factors and markers of vascular change, but were decreased with increased PM2.5. No association was seen between ET-1 and endothelial progenitor cells (EPCs) except for EPC-4, possibly indicating a regulatory relationship with this specific population. In …
