Examining The Oxidative Stress Effects In Rats Exposed To 2-Aminoanthracene In Utero And High Fat Diet Three Months After, Brianna A. Lanoix
Examining The Oxidative Stress Effects In Rats Exposed To 2-Aminoanthracene In Utero And High Fat Diet Three Months After, Brianna A. Lanoix
Honors College Theses
Polycyclic aromatic hydrocarbons are organic compounds that are created synthetically or found in partially burned oil, gasoline, and coal. 2-aminoanthracene (2AA) is a common example of a PAH and can affect lipid and carbohydrate metabolism and resulting in inflammatory problems and oxidative stress. The objective of the research project is to investigate oxidative stress in relation to diabetes in rats exposed to 2AA in utero and a high fat diet later in life. Pregnant dams were separated into treatment groups based on their dosages of 2AA; 0 mg/kg (control), 50 mg/kg (low), 100 mg/kg (high). During the gestation -postpartum period, …
Toxicity And Effects Of Tire Crumb Rubber In The Aquatic Environment, Stephanie Laplaca
Toxicity And Effects Of Tire Crumb Rubber In The Aquatic Environment, Stephanie Laplaca
All Dissertations
Plastic materials have provided innovative solutions to society’s evolving needs and challenges. Due to their durability and resistance to degradation, plastics remain in the environment for long periods of time and can therefore be transported to many environmental compartments such as water, sediment, and biota. Microplastics (MPs) have been defined as synthetic plastic particles that have at least one dimension less than 5 mm and are insoluble in water. Microrubber (MR), a recently acknowledged sub-group of MPs, has been documented in environmental samples more recently, frequently comprising a large portion of total MPs of various samples. In South Carolina specifically, …
Toxic Trace Elements In Follicular Fluid, Oxidative Stress, And In Vitro Fertilization (Ivf) Outcomes, Celeste Danielle Butts
Toxic Trace Elements In Follicular Fluid, Oxidative Stress, And In Vitro Fertilization (Ivf) Outcomes, Celeste Danielle Butts
Legacy Theses & Dissertations (2009 - 2024)
Exposures to environmental contaminants, including non-essential toxic trace elements, may be associated with in vitro fertilization (IVF) outcomes. Follicular fluid (FF) envelops the developing oocyte, offering a “snapshot” of the oocyte microenvironment. FF may better estimate trace element concentrations associated with IVF outcomes than more commonly employed blood and urine biomarkers of exposure. Hence, FF concentrations of four widespread non-essential toxic trace elements (arsenic, mercury, cadmium, and lead) were investigated in relation to a spectrum of IVF endpoints in n=56 women undergoing IVF. Antioxidant activity was explored as an intervening variable and dietary exposure sources of non-essential toxic trace elements …
Addressing Public Health Risks Of Persistent Pollutants Through Nutritional Modulation And Biomimetic Nanocomposite Remediation Platforms, Bradley J. Newsome
Addressing Public Health Risks Of Persistent Pollutants Through Nutritional Modulation And Biomimetic Nanocomposite Remediation Platforms, Bradley J. Newsome
Theses and Dissertations--Chemistry
Due to their relative chemical stability and ubiquity in the environment, chlorinated organic contaminants such as polychlorinated biphenyls (PCBs) pose significant health risks and enduring remediation challenges. Engineered nanoparticles (NPs) provide a novel platform for sensing/remediation of these toxicants, in addition to the growing use of NPs in many industrial and biomedical applications, but there remains concern for their potential long-term health effects. Research highlighted herein also represents a transdisciplinary approach to address human health challenges associated with exposure to PCBs and NPs. The objectives of this dissertation research are two-fold, 1) to develop effective methods for capture/sensing and remediation …
Toxicological Assessment Of Intra‐Tracheal Instilled Nanoceria On Kidneys Of Sprague‐Dawley Rats, Geeta Nandyala
Toxicological Assessment Of Intra‐Tracheal Instilled Nanoceria On Kidneys Of Sprague‐Dawley Rats, Geeta Nandyala
Theses, Dissertations and Capstones
Recent studies suggest that use of nanoceria in industry is associated with increased risk of human and environmental exposure. How inhaled nanoceria might affect the kidneys is not yet known. To investigate this possibility, Sprague Dawley rats were exposed to a single dose of 7mg/kg body weight cerium oxide nanoparticles by intratracheal instillation. Animals were sacrificed at day 1, 3, 14, or 28 days after exposure and the kidneys collected for histological and biochemical analysis. No significant difference was observed in kidney to body weight ratio between the different groups. Hematoxylin and eosin staining did not reveal any significant changes …
