Pulmonary Immune Responses To Respirable Elongate Mineral Particles Of Asbestiform And Non-Asbestiform Morphologies, Timur Khaliullin

Graduate Theses, Dissertations, and Problem Reports

Inhalation exposure to asbestiform elongate mineral particles (EMPs) may cause pulmonary fibrosis, lung and pleural cancer. At the same time, epidemiological evidence for non-asbestiform EMP pathogenicity is scarce, with little if any risk of cancer, but consistent findings of pneumoconiosis and increased mortality. Globally, conditions caused by asbestos exposures contribute most to the occupational cancer burden and are responsible for the increasing mortality for occupational respiratory diseases. Immunological components of the fiber-induced lesions are extremely understudied, partly due to the lack of comparable test articles. In this study I utilized respirable preparations of asbestiform and non-asbestiform riebeckite and tremolite to …

The Use Of Rna Interference To Mitigate Pulmonary Fibrosis In Response To Asbestos Exposure, Sarah Kinsey

Undergraduate Theses, Professional Papers, and Capstone Artifacts

The adverse health effects of exposure to asbestos are widely known and have been well documented. When a person is diagnosed with asbestosis, a chronic lung disease caused by inhaling asbestos fibers, few treatment options exist, none of which halt or reverse the progression of the disease. The rapidly growing field of gene therapy offers new avenues for potential treatments worthy of investigation. The detrimental effects of asbestos exposure are due to the physiological response of the lungs to asbestos fibers in the form of fibrosis, a result of excess extracellular collagen deposition. A protein called SPARC (Secreted Protein Acidic …

Asbestos Exposure In The Research Laboratory, Ediberto D. Garcia

USF Tampa Graduate Theses and Dissertations

Introduction: Asbestos has been employed in a myriad of industrial applications for more than a century. Of the 181 Mt of asbestos produced worldwide, over 31 Mt was consumed in the U.S. The production and consumption of this mineral eventually was found to cause asbestosis, lung cancer and mesothelioma. While the brunt of the human exposure to asbestos occurred in insulation work, many more workers in other jobs were expose to asbestos fibers. Very little is known about the potential exposure to asbestos in research labs.

Goal: In order to investigate potential research lab work exposures, we simulated lab work …
