Electronic Theses and Dissertations
Gastropods are one of the most imperiled groups of animals in North America, yet there are major gaps in the literature pertaining to pollutants and climate change, and especially sublethal impacts. This dissertation assesses the effects of climate warming and unionized ammonia (NH3), one of the most abundant water pollutants, on the behavior and physiology of two caenogastropod snails: fine-ridged elimia (Elimia semicarinata) and Shawnee rocksnails (Lithasia obovata) (Gastropoda: Neotaenioglossa: Pleuroceridae). Righting behavior, or the movement used by snails to turn themselves right-side-up, was used as the main endpoint; delays in this behavior compromise …

Exercise Preconditioning And Tfam Overexpression Diminish Skeletal Muscle Atrophy., Nicholas Todd Theilen
Electronic Theses and Dissertations
This dissertation is an analysis of skeletal muscle atrophy and a molecular assessment of potential preventative treatments. Chapter I begins with a background of skeletal muscle atrophy along with an analysis of associated molecular pathways. Here, we discuss how skeletal muscle atrophy is the consequence of protein degradation exceeding protein synthesis and can occur when a muscle is abnormally disused. The development of therapies prior to skeletal muscle atrophy settings to diminish protein degradation is scarce and could be useful to prevent negative clinical outcomes of patients who must unload and disuse musculature over extended periods. Mitochondrial dysfunction is associated …
