Investigating The Role Of The Skeletal Muscle In Amyotrophic Lateral Sclerosis Neuromuscular Junction Dysfunction, Agnes Badu-Mensah

Electronic Theses and Dissertations, 2020-2023

Neuromuscular junction (NMJ) dysfunction has been identified as one of the earliest events in Amyotrophic Lateral Sclerosis (ALS) pathology. However, which tissue type induces NMJ disruption; be it the motoneurons (hMN), Schwann cells or skeletal muscle (hSKM) remains unresolved. While mechanisms by which ALS hMN contribute to NMJ dysfunction are well-described in literature, limited information exist on how the other tissue types in the tripartite synapse (hSKM and Schwann cells) induce and/or contribute to ALS NMJ disruption. A fair understanding of the role of each tissue type in NMJ dysfunction would help shape the trajectory of future ALS research and …

Concomitant Guillain-Barre Syndrome With Covid-19, Skylar A. Morongell

Honors Undergraduate Theses

The current Coronavirus disease 2019 (COVID-19) outbreak, caused by a virus called severe acute respiratory syndrome 2 (SARS-CoV-2), has become a global health emergency. Recent findings in case studies assert that the transmigration of SARS-CoV-2 to the nervous system implicates severe neurotropic pathologies, including the onset of the rare autoimmune disease called Guillain-Barré syndrome (GBS). GBS is recognized as several disorders characterized by immune-mediated polyradiculoneuropathy, which is typically preceded by an infection or other immune stimulation. The symptoms of GBS initially present as acute symmetrical ascending paresthesia, weakness, and paralysis.

This meta-analysis serves to help understand the predisposing factors (such …

Neuroglobin And Its Role In The Recovery Of Neuronal Cells In Hypoxic Conditions Using Hypoxia Inducible Factor– 1, Riya Shah

Honors Undergraduate Theses

Stroke is the world's leading cause of adult disability, caused by lack of oxygen and nutrients to the brain due to a blood clot in a major artery. This leads to ischemic damage of neuronal cells that leads to paralysis, motor, and speech deficits. While most stroke therapies aim at removing or reducing the blood clots in the brain, few treatments target cell damage. Neuroglobin (NGB) is a protein in the brain that is able to aid in neuroprotection following oxidative stress. Hypoxia-Inducible Factor-1 (HIF-1) is a transcription factor that serves as a marker for cell recovery after hypoxia or …
