Rehabilitative Movement Approaches And Dance Interventions In Parkinson’S Disease, Cecilia Fontanesi

Dissertations, Theses, and Capstone Projects

The scope of this work is to address the functional deficits and symptoms experienced by those living with Parkinson’s Disease through movement interventions.

Chapter 1 offers a brief overview of current pharmacotherapy and rehabilitation approaches in Parkinson’s, focusing on dance in particular as a movement intervention that may be particularly suited to this population.

Chapter 2 focuses on brain plasticity and motor learning in PD, reporting the effects of rTMS applied after the acquisition of a motor skill. In this study, adaptation tested in patients with PD was comparable in the sham and TMS sessions, while retention indices tested on …

Employing High Probability Gene Choice Elements To Understand Singular Odorant Receptor Expression, Raena Mina

Dissertations, Theses, and Capstone Projects

The ability to detect odorous chemicals in the environment is the oldest of the senses necessary for survival, from escaping danger, finding mates, to locating food. It is said that humans can identify and discriminate up to a trillion different odor mixtures. For chemoreception to have such a high discriminatory power, would require a diverse population of cells dedicated for odor detection. These detector cells are the olfactory sensory neurons (OSNs), which express odorant receptors (ORs) that bind to chemical odors in the environment. In order to increase specificity and sensitivity, an essential property in olfaction is for each OSN …

Functions Of Fibroblast Growth Factor Homologous Factor 2 In Excitable Tissues, Christopher Marra

Dissertations, Theses, and Capstone Projects

Purpose: Fibroblast Growth Factor Homologous Factors (FHFs) are a group of proteins known to associate with and modulate voltage-gated sodium channels (Na_v) in excitable cells. The four FHF genes are differentially expressed in specific cell-types, with FHF2 expressed prominently in the hippocampus, cerebral cortex, heart and dorsal root ganglia. Due to previous unavailability of an Fhf2 knockout mouse, this gene’s functions have been understudied in comparison to other those encoding other FHFs. The purpose of this research has been to better understand the normal physiological functions of FHF2 at the cellular and system levels in the heart, sensory …

Tamalin/Gras-1 Connects Glutamate Receptor Activity To The Insulin/Igf Signaling Cascade To Regulate Neuroprotection In A Nematode Model Of Excitotoxicity, Ayesha Chowdhury

Dissertations, Theses, and Capstone Projects

Brain ischemia is a major cause of debilitation and death in the United States. Excitotoxicity, a condition that arises from the accumulation of glutamate (Glu) in the synapse that leads to overactivation of Glu receptors (GluRs), is the major mechanism of neuronal damage in brain ischemia / stroke. Although it is commonly acknowledged that over activation of GluRs leads to neurodegeneration, it has been recently shown that even during excitotoxicity Glu has a concurrent important role in regulating neuroprotection. GluR-activated transcription factors seem to mediate this neuroprotection, but it remains unclear which signaling cascades and transcription factors are regulated by …
