Determination Of Strain Patterns Across The Root-Stem Transition Zone In Trees, Kenneth Edward Beezley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Trees are subjected to mechanical stressors, induced via dynamic (wind) and static (gravitational) forces, and must properly acclimate during their lifespan or face premature mortality. Resource allocation as a stress response is vital for tree survival, and can include the shedding of woody parts, adaptive growth, hormonal signaling cascades, and the initiation of energy transfer mechanisms. The strain resulting from stress intercepted by the canopy and transferred throughout the tree is of significant importance, not only for tree survival, but for the safety and well-being of the human population found in close proximity. As trees age and adapt to stressors …

Cerebrovascular Dysfunction In Metabolic Syndrome And Depression: Mechanisms And Implications For Neurovascular Disease, Steven David Brooks Jan 2016

Cerebrovascular Dysfunction In Metabolic Syndrome And Depression: Mechanisms And Implications For Neurovascular Disease, Steven David Brooks

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cerebrovascular diseases are any pathological conditions that are caused by disruptions or alterations in the blood supply to the brain. The brain, which is only 2% of body mass, constantly requires a minimum of 20% of cardiac output to meet its unique metabolic demands. Cerebral tissue relies on aerobic respiration and therefore requires a constant, steady supply of blood to provide oxygen and glucose to make ATP. Insufficient perfusion of the brain, which occurs as a result of reduced or obstructed blood flow, results in cerebral ischemia; ischemic neurons quickly deplete their available ATP and die if blood flow is …

Effects Of Anti-Viral Acute Phase Response On Hippocampal Glutamate Regulation, Holly C. Hunsberger Jan 2016

Effects Of Anti-Viral Acute Phase Response On Hippocampal Glutamate Regulation, Holly C. Hunsberger

Graduate Theses, Dissertations, and Problem Reports (ETD)

A large body of clinical evidence suggests that viral infections in the periphery can exacerbate neurodegenerative conditions such as Alzheimer's disease, Huntington's, disease, Parkinson's disease, multiple sclerosis, and seizures. The underlying mechanisms of these conditions involve the activation of the acute phase response (APR), part of the innate immune system, which recognizes viral molecular patterns. As neighboring cells become infected, inflammatory mediators are released into the bloodstream and relayed to the central nervous system where they produce a "mirror" inflammatory response. To induce the APR, polyinosinic-polycytidylic acid (PIC), a viral mimetic, is commonly used. PIC produces a robust and transient …

Interleukin-15 Overexpression Attenuates Muscle Fatigue Associated With Murine Eo771 Mammary Tumors, Joseph F. Bohlen Jan 2016

Interleukin-15 Overexpression Attenuates Muscle Fatigue Associated With Murine Eo771 Mammary Tumors, Joseph F. Bohlen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Severe muscle wasting and muscle dysfunction (cachexia) are considered incurable complications associated with a wide variety of chronic diseases. This loss of function and severe wasting causes an increase in fatigue in cancer patients, leading to reduced motivation for daily activities, further reducing prognosis for recovery in these patients leading to a severe increase in morbidity. Recent work from our lab suggests Interleukin-15 (IL-15) induces a pro-oxidative state in the muscle, reducing fatigue and promoting a more oxidative phenotype. One proposed mechanism behind this is the observation that IL-15 promotes mitochondrial biogenesis, lending more mitochondria for oxidative metabolic processes. Therefore, …
