Peripheral And Central Glucose Flux In Type I Diabetes, Jelena Anna Juras

Theses and Dissertations--Neuroscience

Diabetes is a complex metabolic disorder, of which high blood glucose concentration is the primary hallmark. Type I diabetes mellitus (T1DM) is characterized by the lack of insulin production, due to a poorly understood autoinflammatory cascade. In the words of historian Barnett “Diabetes may no longer be a death sentence, but for more and more people in the 21st century, it will become a life sentence”, making it the focal point of many research groups. It is estimated that around 20 million individuals worldwide live with T1DM.

Effects of long-term chronically elevated blood glucose are not only seen in micro/macro-vascular …

Doxorubicin-Induced, Tnf-Α-Mediated Brain Oxidative Stress, Neurochemical Alterations, And Cognitive Decline: Insights Into Mechanisms Of Chemotherapy Induced Cognitive Impairment And Its Prevention, Jeriel T. Keeney

Theses and Dissertations--Chemistry

The works presented in this dissertation provide insights into the mechanisms of chemotherapy-induced cognitive impairment (CICI or “ChemoBrain”) and take steps toward outlining a preventive strategy. CICI is now widely recognized as a complication of cancer chemotherapy experienced by a large percentage of cancer survivors. Approximately fifty percent of existing FDA-approved anti-cancer drugs generate reactive oxygen species (ROS). Doxorubicin (Dox), a prototypical ROS-generating chemotherapeutic agent, produces the reactive superoxide radical anion (O₂^-•) in vivo. Dox treatment results in oxidation of plasma proteins, including ApoA-I, leading to TNF-α-mediated oxidative stress in plasma and brain. TNF-α elevation in brain …
