Looking To The Future Of Stroke Treatment: Combining Recanalization And Neuroprotection In Acute Ischemic Stroke, Michael E. Maniskas

Theses and Dissertations--Neuroscience

Stroke is the 5^th leading cause of death in the U.S. with 130,000 deaths and around 800,000 affected annually. Currently, there is a significant disconnect between basic stroke research and clinical stroke therapeutic needs. Few animal models of stroke target the large vessels that produce cortical deficits seen in the clinical setting. Also, current routes of drug administration, intraperitoneal and intravenous, do not mimic the clinical route of intra-arterial drug administration. To bridge this divide, we have retro-engineered a mouse model of stroke from the current standard of care for emergent large vessel occlusion (ELVO) stroke, endovascular thrombectomy, to …

Disruptions In The Regulation Of Extracellular Glutamate In The Rat Central Nervous System After Diffuse Brain Injury, Jason Michael Hinzman

Theses and Dissertations--Neuroscience

Glutamate, the predominant excitatory neurotransmitter in the central nervous system, is involved in almost all aspects of neurological function including cognition, motor function, memory, learning, decision making, and neuronal plasticity. For normal neurological function, glutamate signaling must be properly regulated. Disrupted glutamate regulation plays a pivotal role in the acute pathophysiology of traumatic brain injury (TBI), disrupting neuronal signaling, initiating secondary injury cascades, and producing excitotoxicity. Increases in extracellular glutamate have been correlated with unfavorable outcomes in TBI survivors, emphasizing the importance of glutamate regulation.

The aim of this thesis was to examine disruptions in the regulation of extracellular glutamate …
