Rescuing Age-Related Proteolysis Deficits With Methylene Blue, Shane E. Pullins
Theses and Dissertations
The average lifespan is constantly increasing with the advent of new medical techniques, and age-related cognitive decline is becoming a prevalent societal issue. Even during healthy aging, humans and rats exhibit progressive deficits in episodic/declarative memory. In laboratory rats, age-related memory impairment can be assessed with trace fear conditioning (TFC). Recent research implicates ubiquitin proteasome system-mediated protein degradation in the synaptic plasticity supporting memory formation and retrieval. In rats, aging leads to decreased basal proteolytic activity in brain structures known to support the acquisition and retrieval of trace fear memories, and our preliminary data suggests activity-dependent proteasome activity declines in …

Association Between Latent Toxoplasma Gondii Infection And Alzheimer's Disease, Cynthia Elizabeth Wyman
Theses and Dissertations
Introduction: Many studies have found an association between Toxoplasma gondii seropositivity and behavioral and cognitive changes in animal models and in humans. In addition, early findings have suggested an association between T. gondii seropositivity and Alzheimer's disease (AD). We sought to determine whether there is an association between T. gondii seropositivity and AD as well as cognitive functioning (including memory, working memory, processing speed, language functioning, executive functioning) in a large, well-characterized sample of subjects with AD and matched controls without dementia. Method: Using ELISA assays, we determined anti-T. gondii IgG antibody titers in 114 control subjects and in 105 …
