The Implementation Of Exercise For Chronic Kidney Disease And Dialysis Patients, Syed Ahmad Rizvi
The Implementation Of Exercise For Chronic Kidney Disease And Dialysis Patients, Syed Ahmad Rizvi
Honors College Theses
While commonly known to be the organ that helps with urine production within the human body, the kidney plays one of the most crucial roles in maintaining homeostasis. When establishing all of the roles the kidney has on keeping humans healthy, there is the question of how does the body cope when a patient is diagnosed with kidney failure. One of the more common treatment options that allows the body to continue to function without a kidney is by beginning a patient on a form of dialysis. However, as with any treatment, there will always be a list of side …
Mixed-Lineage Kinase-3 (Mlk3) Plays A Negative Modulatory Role In Insulin Secretion From The Pancreatic Β-Cell, Tyler Russeth, Vijayalakshmi Thamilselvan, Anjaneyulu Kowluru
Mixed-Lineage Kinase-3 (Mlk3) Plays A Negative Modulatory Role In Insulin Secretion From The Pancreatic Β-Cell, Tyler Russeth, Vijayalakshmi Thamilselvan, Anjaneyulu Kowluru
Medical Student Research Symposium
Glucose-stimulated insulin secretion (GSIS) from the pancreatic β-cell in response to elevated levels of glucose is controlled by a variety of signals including intracellular calcium and nucleotides such as cAMP, ATP and GTP. These cellular signals are responsible for activation of specific kinases that mediate phosphorylation of key exocytotic proteins that lead to GSIS. In the context of protein kinases, mixed-lineage kinases (MLKs) have been implicated in an assortment of cellular functions, including cell proliferation and apoptosis. However, very little is known on potential regulatory roles of MLKs in islet β-cell function, including GSIS. The goal of this study is …
The Dynamics Of Life And Death: Mitochondrial Fragmentation, Mitophagy, And Swelling During Neuronal Ischemia/Reperfusion Injury, Anthony Roy Anzell
The Dynamics Of Life And Death: Mitochondrial Fragmentation, Mitophagy, And Swelling During Neuronal Ischemia/Reperfusion Injury, Anthony Roy Anzell
Wayne State University Dissertations
Ischemic brain injury caused by cardiac arrest or stroke continue to be leading caused of death and disability in the U.S. While restoration of blood flow is necessary to salvage ischemic tissue, reperfusion paradoxically exacerbates injury via the production of reactive oxygen species, which, damage mitochondria and induce cell death. Therefore, it is critical to have stringent quality control mechanisms to ensure a healthy mitochondrial network. Mitochondrial fragmentation has been well characterized in the progression of ischemia/reperfusion and its association with cell death. Conversely, the role of mitophagy has been controversial regarding whether upregulation of mitophagy serves as a restorative …
Causes And Potential Treatment For Altered Muscle Metaboreflex Control Of Ventricular Vascular Interactions In Heart Failure, Joseph Thomas Mannozzi
Causes And Potential Treatment For Altered Muscle Metaboreflex Control Of Ventricular Vascular Interactions In Heart Failure, Joseph Thomas Mannozzi
Wayne State University Dissertations
Muscle Metaboreflex Activation occurs as a result of metabolic accumulation within active skeletal muscle that stimulates type III and IV afferents. This reflex in healthy subjects causes increased ventricular contraction, tachycardia, enhanced central blood volume mobilization, and 2 mediated vasodilation as a means to increase mean arterial pressure and thereby improve perfusion pressure of active skeletal muscle. However, to date no study has evaluated the interaction between the observed changes in ventricular and vascular dynamics or how the reflex impacts contraction relaxation dynamics before and after induction of heart failure Furthermore, no study has evaluated the impact of chronic selective …
Testosterone And Interpersonal Attraction: A Placebo-Controlled Design, Stefan M. Goetz
Testosterone And Interpersonal Attraction: A Placebo-Controlled Design, Stefan M. Goetz
Wayne State University Dissertations
Testosterone has long been implicated as a neuroendocrinological mechanism in the expression of reproductive strategies. Humans the world over form and maintain pair-bonds suggesting that pair-bonds may serve to enhance reproductive fitness. However, infidelity is a perennial threat to these bonds. The data in humans suggests that testosterone is associated with mate-seeking but may be detrimental to relationship maintenance. However, past work has relied on correlational studies and additional findings from nonhuman animal models suggest that acute changes rather than baseline concentrations in testosterone may in fact protect extant pair-bonds. The present research sought to test the causal role of …
