Health disparities, environmental toxicants, and midlife women’s health outcomes
Health disparities and increased exposures to environmental toxicants continue to persist in some of the most vulnerable populations including women from racial and minority groups and older populations. Women from urban areas of developed countries tend to carry the heaviest burdens of both …

Isolating Antigenotoxic Components and Antioxidants From Commercial Corn Processing by -Products
… for setting up prevention strategies for environmental toxicants. Such research may lead to a future where agricultural crops would be raised for both their pharmaceutical and agronomic value. Opening a new niche in the market will result in increased crop value to producers as well as …

Energetic costs of toxicant metabolism in rainbow trout ( Oncorhynchus mykiss)
… are continuously exposed to a variety of environmental toxicants including polychlorinated biphenyls (PCBs). A portion of the energy assimilated by the fish is dedicated to detoxification. This study investigates the changes in energetic demands associated with increased detoxification. …

The Impact of Methylenetetrahydrofolate Reductase (MTHFR) Deficiency in a Paraquat Mouse Model of Parkinson’s Disease
… of Parkinson's disease (PD) remains unknown. Environmental toxicants such as paraquat have been linked to the characteristic dopaminergic (DA) neurodegeneration in the substantia nigra (SN); nutrition may also play a role. A common polymorphism (677C>T) in methylenetetrahydrofolate reductase …

Linking Environmental Toxicant Exposure To Diabetes Susceptibility
<p>An important and unresolved question in the environmental health field is whether exposure to common environmental toxicants, such as dioxin and heavy metals like Pb, increase the risk of developing diabetes, especially in combination with other common metabolic stressors such as obesity. </p> …

Retinal development and age related degeneration following gestational lead exposure
… cells. CONCLUSIONS: Gestational exposure to environmental toxicants such as lead can produce differential age-dependent effects on the developing and aging retina. Furthermore, the lifespan effect of increased proliferation can result in degeneration later in life.

Methods for the Detection of Biological Analytes on Dendritic Surface-Enhanced Raman Scattering (SERS) Substrates
… from biochemical hazards, illicit drugs, and environmental toxicants. These sensors must be portable, affordable, and easy to use. Surface-enhanced Raman scattering (SERS) is a promising method for detecting chemical compounds in various media. However, traditional SERS struggles with direct …

ASSESSING THE GENOTOXICITY OF TRICLOSAN IN TADPOLES OF THE AMERICAN BULLFROG, LITHOBATES CATESBEIANUS.
Amphibians are particularly sensitive to environmental degradation and, therefore, serve as effective environmental quality indicators. Research has suggested that amphibian declines are exacerbated by manmade environmental toxicants, especially those found in high concentrations in urban areas. …

Impacts of perfluorooctanoic acid on porcine oocyte health and competence
… Per- and polyfluoroalkylated substances are environmental toxicants that have been detected in the follicular fluid of women and animals, and which inflict negative effects to oocytes and somatic cells. Perfluorooctanoic acid (PFOA) is a PFAS that is of rising concern to human and animal …

Development of advanced methods for large-scale transcriptomic profiling and application to screening of metabolism disrupting compounds
… of chemical perturbations in order to identify environmental toxicants and characterize their mechanisms-of-action. Further adoption of high-throughput transcriptomic profiling requires continued effort to improve and lower the costs of implementation. Accordingly, my dissertation work …

The Effects of Lead Acetate on Host Susceptibility to Trypanosoma Cruzi
… growing concern in the United States involves environmental toxicants and their ability to act as immunosuppressants. Lead is of particular interest because it is widespread in places such as soil, food, water, batteries, paints, and plastics. Studies have shown lead exposure during bacterial …

The Development and Application of a Hemolytic Plaque Forming Cell Assay (PFC) and a Cytotoxic T-Lymphocyte Assay (CTL) in Tilapia (Oreochromis niloticus) for Immunotoxicity Risk Assessment of Environmental Contaminants
… immune parameters, then tested using fourteen environmental contaminants or drugs, ten of which are classified by the NTP as immunotoxic in rodents. Reduced antibody production via a decrease in plaque number was observed in response to exposure of tilapia to eight of the nine humoral …

The Spatial Relationships among Neurotoxicant Exposure, Child Admissions, and Mental Health Assessment Scores: How do they Interact in the State of Ohio?
… of pounds of known and suspected neurological toxicants were released into the air and water of the United States. Ohio had the dubious distinction of being one of the worst offenders because it was in the top-five emitters nationally (U.S. EPA, 2009a). While environmental toxicants are harmful …

Later Life Consequences of Developmental Mitochondrial DNA Damage in C. elegans
… than nuclear DNA (nucDNA) to damage by many environmental pollutants, for reasons including the absence of Nucleotide Excision Repair (NER) in the mitochondria [7]. NER is a highly functionally conserved DNA repair pathway that removes bulky, helix distorting lesions such as those caused by …

Systems Genetics and Systems Biology Analysis of Paraquat Effects in BXD Recombinant Inbred Mice
… it is the result of the interaction between environmental factors and genetic susceptibility. Increasing evidence led us to infer a relationship between iron metabolism in the brain, environmental toxicants like paraquat, and sPD. Our hypothesis is that variable genetic factors contribute to …
