Cancer Stem Cells In The Screening Of Anticancer Drugs For Central Nervous System Tumors, Sarah Elizabeth Daron-Mathis

Theses, Dissertations and Capstones

There is a growing need (in the medical field) to design personalized therapy for cancer patients. Decades of cancer research have found no silver bullet that can cure all or even most patients. This study evaluated four patients affected by central nervous system (CNS) tumors (Ependymoma and Glioblastoma), and found that tumors with the same histology had unique responses to treatment. Each sample presented different levels of heterogeneity in expressed biomarkers and responded to drugs at varying levels.

Oncologists conventionally treat cancer patients with drugs tested in large clinical trials. However, often patients do not experience positive outcomes following treatments …

Creutzfeldt-Jakob Disease And Alzheimer’S Disease: Does Overlap Of Mechanism Mean Overlap Of Treatment Methods?, David Rotblat

The Science Journal of the Lander College of Arts and Sciences

Alzheimer’s disease is a neurodegenerative disorder that is the 6th leading cause of death in the United States. More than 5.5 million People over the age of 65 are currently diagnosed with Alzheimer’s disease with predictions of 13.8 million to be diagnosed by the year 2050 (Sultana, et al., 2013) (Hebert, Weuve, Scherr, & Evans, 2013). With few treatments available, scientists are desperately looking for a solution to this growing epidemic. Creutzfeldt-Jakob disease is also a neurodegenerative disorder, but with a far less prevalence of only 4.6 persons per million per year. It was discovered that Alzheimer’s and Creutzfeldt-Jakob disease …

The Clinical Utility Of Multidisciplinary Rehabilitation In Individuals With Huntington’S Disease, Travis Miles Cruickshank

Theses: Doctorates and Masters

Background

Huntington’s disease (HD) is a chronic neurodegenerative disorder characterised by a progressive loss of cognitive function, motor control and psychiatric features. Individuals also display a variety of systemic features. Progressive neuronal dysfunction and neuronal cell death are thought to underlie the onset and progression of many clinical features of HD.

Despite scientific progress, there is still no cure or disease modifying therapy for HD, and available pharmaceutical agents only provide partial relief of motor and psychiatric features. An emerging body of evidence indicates that lifestyle enrichment may delay the onset and progression of clinical features, and exert favourable effects …

The Effect Of Optogenetic Manipulation Of Ss Interneurons Within Malformed, Epileptogenic Cortex, Nicole Ekanem

Theses and Dissertations

A large percentage of individuals with intractable epilepsies have an accompanying cortical malformation, the underlying cellular mechanisms of which are poorly understood. It is known however that in an animal model for one such malformation, polymicrogyria, epileptogenesis occurs most easily from an adjacent area termed the paramicrogyral region (PMR). Previous studies implicate SS interneurons as a potential contributor to this pathology, which lead to our hypothesis: in PMR, SS interneurons exert a higher modulatory influence on excitatory pyramidal cells, as compared to the same by SS interneurons within homologous control cortex.

Using a freeze-lesion model for polymicrogyria in transgenic mice …

Axon Initial Segment Stability In Multiple Sclerosis, Suneel K. Thummala

Theses and Dissertations

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system characterized by inflammation and demyelination. In addition to these hallmark features, MS also presents with axonal pathology, which is likely responsible for the signs and symptoms of the disease. Although prominent in MS, axonal pathology is frequently considered a consequence of demyelination and not a primary event. This conclusion is consistent with demyelination inducing the loss of specific axonal domains, known as the nodes of Ranvier that are responsible for the propagation of action potentials along the axon. In contrast, we propose that axonal pathology associated with MS …

Role Of Sigma-1 Receptors In Neurodegenerative Diseases, Linda Nguyen, Brandon P. Lucke-Wold, Shona A. Mookerjee, John Z. Cavendish, Matthew J. Robson, Anna L. Scandinaro, Rae Reiko Matsumoto

Faculty Publications & Research of the TUC College of Pharmacy

Neurodegenerative diseases with distinct genetic etiologies and pathological phenotypes appear to share common mechanisms of neuronal cellular dysfunction, including excitotoxicity, calcium dysregulation, oxidative damage, ER stress and mitochondrial dysfunction. Glial cells, including microglia and astrocytes, play an increasingly recognized role in both the promotion and prevention of neurodegeneration. Sigma receptors, particularly the sigma-1 receptor subtype, which are expressed in both neurons and glia of multiple regions within the central nervous system, are a unique class of intracellular proteins that can modulate many biological mechanisms associated with neurodegeneration. These receptors therefore represent compelling putative targets for pharmacologically treating neurodegenerative disorders. In …

Treating Acute Migraines: Triptans Vs. Antiemetics, Samuel Reisman

The Science Journal of the Lander College of Arts and Sciences

Influential American medical organizations and publications have published guidelines for the treatment of acute migraine headaches that omit antiemetics, usually suggesting triptans as the first line of treatment. A review of the few comparative studies directly contrasting clinical outcomes of triptans and antiemetics in the treatment of acute migraines suggest that both treatment options are relatively equal in efficaciousness. The added burden of triptan usage, including an added risk of adverse effects and a high cost per dose, would seem to warrant an antiemetic-first approach to migraine treatment, as recommended by several international health communities. Possible reasons for the prominent …

Is There A Link Between Saturated Fat Intake And Alzheimer’S Disease?, Justin Konig

The Science Journal of the Lander College of Arts and Sciences

Alzheimer’s disease is a neurodegenerative disease that causes dementia and ultimately death. Currently, there is no treatment available for this disease. The aging of the population will only increase the incidence of Alzheimer’s disease, making it ever more important to find an effective method of prevention. Dietary intervention is a practical and affordable method of intervention. The brain is a fat rich organ, and dietary fats are critical for proper development of the brain. A literature review was conducted to determine whether there is a link between saturated fat intake and Alzheimer’s disease. According to the literature reviewed, saturated fat …

Amyotrophic Lateral Sclerosis (Als) And Spinal Muscular Atrophy (Sma): A Genetic Linkage?, Michael Groden

The Science Journal of the Lander College of Arts and Sciences

Neurodegenerative motor neuron disorders (MNDs) have devastating effects. Spinal Muscular Atrophy (SMA), for example, is a debilitating and sometimes lethal disease in children. SMA is monogenic, autosomal recessively inherited disorder caused by a loss-of-function mutation of surviving motor neuron 1 (SMN1). SMN2 is an identical copy of this gene and produces abbreviated transcripts without exon 7 though some full transcripts are produced that ameliorate the disease. Previous clinical trials for this disease have not produced consistent results. However, in a recent cross-sectional study, biomarkers for SMA (BforSMA), protein candidates and metabolite markers were identified (Finkel et al., 2012). These markers …

Dietary Selenium Supplementation: Effects On Neurodegeneration Following Traumatic Brain And Spinal Cord Injury, Carolyn A. Crowdus Meyer

Theses and Dissertations--Neuroscience

Traumatic brain and spinal cord injury continue to be substantial clinical problems with few available treatment strategies. Individuals who are at a greater risk for sustaining a central nervous system (CNS) injury, such as professional athletes and military personnel, may benefit from a prophylactic supplement that would intervene in the neurodegenerative pathways immediately following injury. The high demand for selenium within the central nervous system, as well as the synthesis of selenoproteins by neurons and astrocytes suggests a critical role of selenium within the brain and spinal cord. Studies were designed to test the efficacy of enriched dietary selenium status …

Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster

Theses and Dissertations--Clinical and Translational Science

This dissertation introduces a framework for understanding differences in how emotional enhancement effects might influence memory in aging adults and then summarizes the findings of three studies of how repetition effects and emotional enhancement effects influence working memory in older adults without cognitive impairment (NC), older adults with amnestic mild cognitive impairment (MCI), and older adults with mild Alzheimer’s disease (AD). In these experiments, individuals with AD showed cognitive impairment in terms of accuracy and reaction time, but individuals with MCI showed milder behavioral impairment that was confined to manipulations of working memory. Individuals with AD showed relative sparing of …

The Effectiveness Of A Computer-Assisted, Cognitive-Behavior Program For Treating Anxiety Symptoms In Children With Autism Spectrum Disorder, Jennifer A. Zabel

The N-Glycosylation Of Immunoglobulin G As A Novel Biomarker Of Parkinson’S Disease, Alyce Christine Russell

Theses: Doctorates and Masters

For neurodegenerative diseases, interventions during the early stages of the disease, before significant neurodegeneration has occurred, are associated with an increased probability of slowing or halting the disease process. In order to intervene early, it is essential that an accurate diagnosis is obtained and that disease progression can be monitored. This is particularly relevant for Parkinson’s disease (PD; International Classification of Diseases version 10) because significant neurodegeneration has already occurred by the time the clinical motor symptoms are present. Therefore, the development of translatable, high-throughput biomarkers for large scale population screening is a crucial area of research. Of promise are …

Cloned Microglias With Novel Delivery System In Multiple Sclerosis, Abdul Mannan Baig Dr.

Department of Biological & Biomedical Sciences

Multiple Sclerosis (MS) is a chronic inflammatory neurological disease of the Central Nervous System (CNS), characterized by demyelination and activation of microglia. Mitochondrial mutations and dysfunctions in microglial cells are thought to contribute to the detrimental effects of neuroinflammation seen in MS. The Somatic Nuclear Transfer (SCNT) technology offers a more practical mode of therapy in MS, this method would attempt to dilute and/or progressively replace the mutated and activated microglia with cloned Olfactory Ensheathing Cells (OEC) with remyelinating and scavenging properties which would attempt to limit the progression of MS. Applying SCNTderived Embryonic Stem (ES) cells based therapy by …

Neural Stem Cells As A Model To Study Huntington’S Disease, Rawan Bakhsh

Dissertations, Masters Theses, Capstones, and Culminating Projects

Huntington’s disease (HD) is a heritable neurodegenerative disorder that affects muscle coordination and diminishes cognitive abilities, by affecting the medium spiny neurons in the brain. In HD patients, neurons are damaged and destroyed because of the toxicity of the mutant Huntington protein (mHtt). The mechanism of how mHtt protein affects the neurons is unknown. In this study we explored the effects of mHtt expression by looking at changes in huntingtin localization, changes in the expression and co-localization of related proteins and differences in cell morphology. We examine how this expression affects the cytoskeletal structures using neural stem cells Q7 (wild …
