Transgenic Mouse Model Of Tau Pathology In Astrocytes Leading To Nervous System Degeneration, Deepa V. Dabir

Biology Faculty Works

Filamentous tau inclusions in neurons and glia are neuropathological hallmarks of sporadic and familial tauopathies. Because tau gene mutations are pathogenic for the autosomal dominant tauopathy "frontotemporal dementia and parkinsonism linked to chromosome 17," tau abnormalities are implicated directly in the onset and/or progression of disease. Although filamentous tau aggregates are acknowledged to play roles in degenerative mechanisms resulting in neuron loss, the contributions of glial tau pathology to neurodegeneration remain essentially unexplored. To begin to elucidate the role of glial pathology in tauopathies, we generated a transgenic (Tg) mouse model of astrocytic tau pathology by expressing the human tau …

Vegetation And Hydrologic Influences On Carbon And Nitrogen In Subsurface Water Of A Forested Riparian Wetland, Emily B. W. Calhoon

Dissertations, Master's Theses and Master's Reports - Open

Vegetation communities affect carbon and nitrogen dynamics in the subsurface water of mineral wetlands through the quality of their litter, their uptake of nutrients, root exudation and their effects on redox potential. However, vegetation influence on subsurface nutrient dynamics is often overshadowed by the influences of hydrology, soils and geology on nutrient dynamics. The effects of vegetation communities on carbon and nitrogen dynamics are important to consider when managing land that may change vegetation type or quantity so that wetland ecosystem functions can be retained. This study was established to determine the magnitude of the influences and interaction of vegetation …
