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 ...
Bringing Toxicology Into The 21st Century: A Global Call To Action, 2016 Humane Society International
Bringing Toxicology Into The 21st Century: A Global Call To Action, Troy Seidle, Martin Stephens
Martin Stephens, Ph.D.
Conventional toxicological testing methods are often decades old, costly and low-throughput, with questionable relevance to the human condition. Several of these factors have contributed to a backlog of chemicals that have been inadequately assessed for toxicity. Some authorities have responded to this challenge by implementing large-scale testing programmes. Others have concluded that a paradigm shift in toxicology is warranted. One such call came in 2007 from the United States National Research Council (NRC), which articulated a vision of ‘‘21st century toxicology” based predominantly on non-animal techniques. Potential advantages of such an approach include the capacity to examine a far greater ...

Effect Of Bisphenol-A On Neurodevelopment In Drosophila Melanogaster Larvae, 2016 College of Saint Benedict/Saint John's University
Effect Of Bisphenol-A On Neurodevelopment In Drosophila Melanogaster Larvae, Alexandra M. Streifel
All College Thesis Program
This paper examines the effects of the chemical preservative bisphenol-A on the developing nervous systems of Drosophila melanogaster, or fruit fly, larvae. This study examines the effects of bisphenol-A using both behavioral as well as morphological paradigms. It was determined that bisphenol-A significantly increased the amount of time larvae spent in seeking behavior, the number of peristaltic contractions, and the distance traveled in a linear fashion. In the morphological analysis, indications of increased dendritic area in experimental larvae existed, but there was not enough data to determine significance. For future research, it is recommended that more data be gathered to ...

Evaluation Of Pulmonary Function Among Workers Engaged In The Manufacture Of Hydraulic Fracking Proppant, Humairat H. Rahman
Graduate Theses and Dissertations
Workers involved in hydraulic fracking processes are exposed to various types of chemicals and dusts in their workplaces, such as proppants, which hold open the fissures created in the fracking process. Recently, ceramic proppants have been developed that may be less hazardous to workers than traditional proppants. Pulmonary function testing of workers producing ceramic proppant was used to assess the potential inhalation hazards of ceramic proppant. Male workers (n = 100) from a producer of ceramic proppant were evaluated with pulmonary function test data collected and evaluated using The American Thoracic Society (ATS) acceptability criteria. A comparison group was selected from ...
Human Health Risk Characterization Of Petroleum Coke Calcining Facility Emissions, 2016 University of South Florida
Human Health Risk Characterization Of Petroleum Coke Calcining Facility Emissions, Davinderjit Singh
Graduate Theses and Dissertations
Calcined coke is a high quality carbon material produced by calcining green petroleum coke. Calcining is the process of heating green petroleum coke in a kiln to remove excess moisture, extract all remaining hydrocarbons, and modify the crystalline structure of the coke into a denser, electrically conductive product. The final product, calcined coke, is primarily used to make carbon anodes for the aluminum industry and recarburizing agent for industries such as the steel industry. If not appropriately controlled, the calcining process could lead to excess production of particulate emissions from either handling or storing of raw coke, or from the ...
