Therapeutic Potential Of A Ketogenic Diet In The Treatment Of Major Depressive Disorder, Jordan A. Murrin
Therapeutic Potential Of A Ketogenic Diet In The Treatment Of Major Depressive Disorder, Jordan A. Murrin
Masters Theses, 2020-current
Major depressive disorder (MDD) is the second most common mental health condition and a leading cause of disability in the world. It is theorized that MDD develops from a combination of biological, psychological, and social stressors. The condition is typically treated using pharmaceuticals and psychotherapy. However, not all individuals with MDD have access to or choose to use these treatments, or may prefer to incorporate therapeutic lifestyle changes such as exercise, sleep, and healthy eating. Even with treatment, MDD can alter brain structure and function, leading to the development of comorbid mental health and chronic metabolic conditions like obesity, cardiovascular …
Hormonal Regulation Of Glycine Decarboxylase And Its Metabolic Outcomes, Ruta Milind Jog
Hormonal Regulation Of Glycine Decarboxylase And Its Metabolic Outcomes, Ruta Milind Jog
Wayne State University Dissertations
The amino acid glycine is involved in generation of multiple critical metabolites including glutathione, heme, and creatinine. Interestingly, in both humans and rodents, circulating glycine levels are significantly reduced in obesity, glucose intolerance, type II diabetes and non-alcoholic fatty liver disease. The glycine cleavage system is the predominant glycine degradation pathway in humans. The rate-limiting enzyme of glycine cleavage system is glycine decarboxylase (GLDC), and loss-of-function mutations of GLDC cause hyperglycinemia. Here, we show that GLDC gene expression is upregulated in livers of mouse models of diabetes and diet-induced obesity as well as in the fasted state in normal animals. …
Mechanisms Of Dopamine-Induced Methamphetamine Neurotoxicity, Melinda L. Asbury
Mechanisms Of Dopamine-Induced Methamphetamine Neurotoxicity, Melinda L. Asbury
Theses, Dissertations and Capstones
Methamphetamine (MA) neurotoxicity is particularly evident in the striatum where it causes extensive dopamine (DA) release and results in neurodegeneration. To identify specific signaling pathways and macromolecules involved in postsynaptic DA-induced striatal toxicity we used a SK-N-MC cell model that mimics postsynaptic D1 receptor-expressing striatal neurons. The cells were treated for 6-24 h with 0-50 µM DA. The concentration was chosen to impart physiological relevance to the study as it mirrors [DA] found within the striatum following MA exposure. We show that 25-50 µM DA resulted in protein changes consistent with nitro(oxidative) stress as well as enhanced cleavage of caspase …
Oxidative Stress Analysis Of Placental Tissue In The Rupp Pregnant Rat, Natalie Ganios
Oxidative Stress Analysis Of Placental Tissue In The Rupp Pregnant Rat, Natalie Ganios
Williams Honors College, Honors Research Projects
Preeclampsia is a disease associated with a vasoconstrictive phenotype due to disrupted signaling in the vascular endothelial growth factor (VEGF) relaxation pathway. The purpose of these studies is to determine the level of oxidative damage that is occurring in the placenta of the reduced uterine perfusion pressure (RUPP) rat, which serves as a common model for preeclampsia. RUPP and SHAM placenta tissue will be examined for oxidative stress as an indicator of tissue damage associated with the pathologically induced ischemia. Oxidative stress in the placental tissue will be measured by performing the following oxidative stress assays: 8-isoprostane test, TBARS assay, …
