Sensitivity Of Quagga Mussels (Dreissena Rostriformis Bugensis) To Cyanobacteria At Multiple Life History Stages, Anna Boegehold
Sensitivity Of Quagga Mussels (Dreissena Rostriformis Bugensis) To Cyanobacteria At Multiple Life History Stages, Anna Boegehold
Wayne State University Dissertations
Quagga mussels (Dreissena rostriformis bugensis) originate from brackish waters of the Ponto-Caspian area and are nuisance invasive species in North American and European freshwaters. Their invasion has caused major economic and ecological damages in the Laurentian Great Lakes. Through selective filter feeding, quagga mussels have promoted the growth of cyanobacteria. Harmful cyanobacteria blooms have the potential to produce toxins, which can be toxic to humans and wildlife. Although quagga mussels can increase the prevalence of cyanobacteria blooms, it is unknown how they are physiologically affected by cyanobacteria and understanding these dynamics can be useful in the management of this invasive …

Linking Environmental Toxicant Exposure To Diabetes Susceptibility, Jannifer Beth Tyrrell
Wayne State University Dissertations
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.
Previous studies suggested that dioxin exposure increased peripheral insulin resistance but did not appear to cause fasting hyperglycemia or elevated hepatic glucose output. In concordance with those findings we observed that dioxin treatment caused a strong suppression of the expression of the key hepatic gluconeogenic genes PEPCK and G6Pase. However, this suppression was not solely mediated by the …
