Understanding The Mechanism Of Oxidative Stress Generation By Oxidized Dopamine Metabolites: Implications In Parkinson's Disease, Nihar Mehta
Wayne State University Dissertations
Oxidation of dopamine to toxic metabolites is considered to be one of the prime factors involved in the death of dopaminergic neurons in Parkinson’s disease. Some dopamine oxidation products have the capability to redox cycle in the presence of molecular oxygen, further contributing to oxidative stress. Therefore, our aim here was to study the redox cycling of dopamine oxidized metabolites and elucidate the underlying mechanism by which they cause oxidative stress.
Redox reactions involve transfer of one or more electrons between two compounds
resulting in either oxidation or reduction. In redox cycling, a compound undergoes
alternate oxidation and reduction, transferring …
Analysis Of The Secondary Neurodegenerative Consequences Of Primary Oligodendrocyte Stress Through The Use Of The Novel Obiden Mouse Model, Daniel Zdzislaw Radecki
Analysis Of The Secondary Neurodegenerative Consequences Of Primary Oligodendrocyte Stress Through The Use Of The Novel Obiden Mouse Model, Daniel Zdzislaw Radecki
Wayne State University Dissertations
The work of this project was to develop, test and characterize a potential novel mouse model of the neurodegenerative disease Multiple Sclerosis (MS). Historically, MS has been identified as a primary autoimmune disease of the central nervous system (CNS). However, treatments based on this view have met with limited success, and in most cases, fail to prevent progression of MS from mild to moderate and severe forms. Original observations regarding axonal and neuronal pathology in the white and gray matter of the CNS were rediscovered in the 1990s. These observations indicated that even in the absence of the immune system, …
Estimating The Variables Of The Nonlinear Dynamical Theory Of Acute Cell Injury, Fika Tri Anggraini
Estimating The Variables Of The Nonlinear Dynamical Theory Of Acute Cell Injury, Fika Tri Anggraini
Wayne State University Dissertations
This Dissertation is the first to estimate the variables D and S of the nonlinear theory of acute cell injury in hippocampal regions CA1 and CA3 using a rat model of global brain ischemia and reperfusion (I/R). D was estimated by quantifying protein aggregates using ubiquitin Western blotting. S was estimated by quantifying changes in polysomal mRNAs as measured by microarray chips. D and S time courses were sampled at 0.5, 8, 16, 24, 48, and 72 hrs of reperfusion after 10 min brain ischemia. CA1 dies and CA3 survives. The theory predicts D will be larger in CA1 and …
