Tumor Necrosis Factor Α Inhibition For Alzheimer's Disease, Rudy Chang, Kei-Lwun Yee, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Tumor necrosis factor α (TNF-α) plays a central role in the pathophysiology of Alzheimer’s disease (AD). Food and Drug Administration–approved biologic TNF-α inhibitors are thus a potential treatment for AD, but they do not cross the blood-brain barrier. In this short review, we discuss the involvement of TNF-α in AD, challenges associated with the development of existing biologic TNF-α inhibitors for AD, and potential therapeutic strategies for targeting TNF-α for AD therapy.

Characterization Of Neuronal Specific Responses To Induced Misfolded Protein Stress In Caenorhabditis Elegans, Claire Gormley

Senior Honors Projects, 2010-2019

Abstract

Misfolded protein stress has been associated with many types of disease,

including neurodegenerative disorders like Alzheimer’s, Parkinson’s and Huntington’s

disease. When a cell accumulates misfolded proteins in the endoplasmic reticulum,

misfolded protein stress occurs and the unfolded protein response (UPR) is triggered to

induce mechanisms that will allow the cell to either survive or undergo cell death. The

nascent polypeptide associated complex (NAC) is a co-translational chaperone and α/β

heterodimer that manages protein folding and localization, and protects against misfolded

protein stress; changes in NAC function have been linked to both neurodegeneration and

cancer. In these studies, I depleted …

Rat Hind Limb Nociceptive Withdrawal Response To Heat And Mechanical Stimuli Depends On Initial Position Of The Paw But Not Stimulus Location, Giavanna Verdi

Senior Honors Projects, 2010-2019

Mammals rapidly withdraw their hind limb in response to noxious stimulation, which is a protective movement known as the nociceptive withdrawal response (NWR). The NWR has been previously studied in spinalized, decerebrated and anesthetized non-human and human mammals; however, there is minimal information on the NWR in intact, unanesthetized non-human mammals.

The first specific aim was to identify the factors that determine the direction and magnitude of the NWR in intact, unanesthetized rats. Based on previous studies, we hypothesized that the location of stimulation and the initial position of the paw preceding the NWR will influence the direction and magnitude …

The Role Of The Expansion Segment 7 Of 25s Rrna During Oxidative Stress In Saccharomyces Cerevisiae, Ethan Gardner

Graduate School of Biomedical Sciences Theses and Dissertations

Translation is an essential process for protein expression in both eukaryotes and prokaryotes. Like any cellular process, translational factors are prone to damage when the cell is under stress. One common stressor that nearly all cells may experience is abnormal levels of reactive oxygen species (ROS). Damage caused by ROS has been associated with disease ranging from neurodegenerative impairments, to the aging process of cells. These oxygen radicals are capable of damaging a litany of molecules including nucleic acids, and molecular factors involved in translation. It has been shown that tRNA can be cleaved upon ROS-induced stress and these fragments …

Mri Analysis Of White Matter Myelin Water Content In Multiple Sclerosis: A Novel Approach Applied To Finding Correlates Of Cortical Thinning, Michael Dayan, Sandra M. Hurtado Rua, Elizabeth Monohan, Kyoko Fujimoto, Sneha Pandya, Eve M. Locastro, Tim Vartanian, Thanh D. Nguyen, Ashish Raj, Susan A. Gauthier

Mathematics and Statistics Faculty Publications

A novel lesion-mask free method based on a gamma mixture model was applied to myelin water fraction (MWF) maps to estimate the association between cortical thickness and myelin content, and how it differs between relapsing-remitting (RRMS) and secondary-progressive multiple sclerosis (SPMS) groups (135 and 23 patients, respectively). It was compared to an approach based on lesion masks. The gamma mixture distribution of whole brain, white matter (WM) MWF was characterized with three variables: the mode (most frequent value) m1 of the gamma component shown to relate to lesion, the mode m2 of the component shown to be associated with normal …

The Role Of Advanced Glycation End Products (Ages) Through The Trpa-1/Nrf-2 Activation Pathway In The Neurodegenerative Diseases, Sana Khateeb

Dissertations, Masters Theses, Capstones, and Culminating Projects

The posttranslational modification of macromolecules caused by highly reactive and toxic α-dicarbonyls, such as methylglyoxal (MGO) derived from glycolysis, is associated with various age-related diseases including diabetic complications and neurodegenerative diseases. Aging and long-term hyperglycemia causes enhanced production of this highly reactive α-dicarbonyl, which reacts with macromolecules causing irreversible damage of DNA and protein promoting the formation of advanced glycation end products (AGEs). The formation and accumulation of AGEs in different cell types affect intracellular and extracellular structure and function. AGEs can also cause macrovascular and microvascular complications through the formation of cross-links between key molecules, permanently altering cellular structure …

Trunk And Respiratory Motor Control In Typically Developing Children And Its Implications In Children With Chronic Spinal Cord Injury., Goutam Singh

Electronic Theses and Dissertations

Independent sitting is a major milestone and is also a prerequisite for optimal performance of activities of daily living (ADLs). Development of sitting posture control is a dynamic process involving control of degrees of freedom of head and trunk. Traditionally, trunk has been modeled as a single unit (segment). However, recent studies have suggested that it is made up multiple spinal units, controlled by a combination of trunk muscles. During typical development, posture control of trunk is different for different trunk segments. This motor development of trunk control is a complex process due to constant interaction between the nervous system …

Effects Of A Scripted Online Video On School Nurse Perceptions Of Concussion Management, Kathleen Holligan Schneider

Nursing Theses and Dissertations

Media attention surrounding the increased rates and serious consequences of concussions among American youths has instigated the passage of laws in all fifty states requiring improved management of concussions and the development of programs, such as the Center for Disease Control and Prevention, Heads Up to Concussion. Progress has been reported in the efficacy of concussion diagnosis and return-to-play decisions. However, there has been less progress in managing the protocols for cognitive rest and return-to-classroom. The purpose of this study was to identify significant stakeholders and factors that could improve management of cognitive rest and return-to-classroom protocols in high …

Network Exploration Of Correlated Multivariate Protein Data For Alzheimer's Disease Association, Matthew J. Lane

Theses

Alzheimer Disease (AD) is difficult to diagnose by using genetic testing or other traditional methods. Unlike diseases with simple genetic risk components, there exists no single marker determining as to whether someone will develop AD. Furthermore, AD is highly heterogeneous and different subgroups of individuals develop the disease due to differing factors. Traditional diagnostic methods using perceivable cognitive deficiencies are often too little too late due to the brain having suffered damage from decades of disease progression. In order to observe AD at early stages prior to the observation of cognitive deficiencies, biomarkers with greater accuracy are required. By using …

The Use Of Rhyme, Rhythm, And Melody As A Form Of Repetition Priming To Aid In Encoding, Storage, And Retrieval Of Semantic Memories In Alzheimer’S Patients, Faiz Plastikwala

Virginias Collegiate Honors Council Conference

Treating Alzheimer’s disease, especially through non-pharmaceutical means, has become increasingly important over the past few decades. I examined the use of melody, rhyme, and rhythm as encoding mechanisms to aid in the retrieval of long term semantic information by juxtaposing previous experiments in the field. Melody, rhyme, and rhythm provide an organizational structure to facilitate the encoding of information. Specifically, chunking, the grouping of smaller units into larger ‘chunks’, helps facilitate long term encoding in patients, and is the byproduct of the organizational structure of a text. A major drawback of using these devices is the loss in the depth …

Medical Resource Utilization Of Outpatient Care For Children With Neurofibromatosis Type 1, Rabia Idrees, Michael Fisher, Rachel Hachen, Brian Callaghan, Robert A. Avery

GW Research Days 2016 - 2020

Background:

Neurofibromatosis Type 1 (NF1) is an autosomal dominant syndrome with manifestations affecting the central nervous system, musculoskeletal system, peripheral nervous system, and cognitive/behavioral functions. Many of these manifestations persist throughout life and require medical/surgical interventions.

The resource utilization and economic burden of caring for children with NF1 is unknown. Prior research has inherent selection bias and does not accurately reflect the incidence/resource utilization of morbidities. In order to identify which disease manifestations are in the most need of improved clinical algorithms and novel therapeutics, the frequency/type of resources utilized (i.e., diagnostic imaging and specialty visits) must be determined.

Differential Mrna Expression In Ectopic Germinal Centers Of Myasthenia Gravis Thymus, Manjistha Sengupta, Bi-Dar Wang, Norman H. Lee, Gary Cutter, Linda L. Kusner, Henry J. Kaminski

GW Research Days 2016 - 2020

Myasthenia gravis (MG) is an autoimmune neuromuscular disorder resulting in weakness of voluntary muscles. It is caused by antibodies directed against proteins present at the post-synaptic surface of neuromuscular junction (NMJ). A characteristic pathology of patients with early onset MG is thymic hyperplasia with ectopic germinal centers (GC). However, mechanisms that trigger and maintain thymic hyperplasia are poorly characterized.

In order to determine the central mechanisms involved in the pathology, thymus samples from MG patients were assessed by histology and grouped based on appearance of GC compared to samples without them. We assessed the differential mRNA expression profiles between the …

P30. Optimizing Current Steering In Deep Brain Stimulation For Treating Parkinsonian Axial Motor Symptoms, Daphne Hui

Western Research Forum

Background: The proposed study will investigate deep brain stimulation (DBS), of the subthalamic nucleus (STN) to improve gait dysfunctions in advanced Parkinson’s Disease (PD). DBS requires implantation of electrodes into the brain that contain contacts where current traverses to stimulate neurons. Imprecise electrode implantations are inherent in surgical implantation; thus, contributing to the elusiveness of DBS on gait.

Methods: The proposed investigation will divide current between two contacts to receive 0, 30, 50, 70, or 100% of current, to find the best combination to improve gait. Gait changes associated with fractional combinations will be visually assessed with clinical scales, and …

P35. Investigating The Effect Of Maternal Immune Activation On Sensory Filtering, Social Behaviour And Attention, Faraj Haddad

Western Research Forum

Background

Altered brain development is associated with many neuropsychiatric disorders like Autism Spectrum Disorder (ASD) and schizophrenia. Environmental insults can interfere with neurodevelopment, and a prominent example is maternal infection during pregnancy. Epidemiological studies show that children born to mothers who were infected during pregnancy display a higher risk of developing ASD and schizophrenia, and this effect is mainly due to the maternal immune response. Polyinosinic-polycytidilic acid (Poly I:C) is a double stranded RNA molecule that mimics viral markers and elicits an immune response. When injected in pregnant rodents, this model produces offspring that exhibit core symptoms of ASD and …

Parental Quality Of Life 10 Years After Their Child’S Epilepsy Diagnosis, Klajdi Puka, Kathy Nixon Speechley

Western Research Forum

Background: Although the long-term course of childhood epilepsy is favorable in terms of seizure control, patients often face debilitating cognitive and psychosocial deficits that persist even after seizure remission. Pediatric epilepsy also has a large impact on the family and has been shown to be associated with diminished quality of life (QOL) among parents. However, the long-term outcome of parental QOL is unknown. This study aimed to 1) evaluate parental QOL 10 years after their child was diagnosed with epilepsy and 2) identify epilepsy-, child- and family-related characteristics associated with diminished parental QOL.

Methods: Data were derived …

Brivaracetam (Briviact): A Novel Adjunctive Therapy For Partial-Onset Seizures, Farbod Khaleghi, Eric C. Nemec

Physician Associate Studies Faculty Publications

Epilepsy is the fourth most common neurological disorder and affects more than 65 million individuals worldwide.This condition is marked by the presence of epileptic seizures, which result from an abnormal synchronous firing of excitatory neurons in the brain. When neurons fire synchronously, a wave of depolarization known as a paroxysmal depolarizing shift occurs. During this period, the neurons experience a lowered resistance to firing, leading to multiple action potentials that generate abnormally increased electrical activity within the brain.

Dosing Of Education For Patients Newly Diagnosed With Multiple Sclerosis, Laura K. Miller

The main focus of this study is to evaluate the timing of patient education in correlation with the time since diagnosis. The goal of this study is to make recommendations for the optimal time in which patient education should be delivered following a diagnosis of Multiple Sclerosis (MS). This study evaluates self-advocacy using the Patient Self-Advocacy Scale (PSAS) which was completed pre and post educational programs. This data, combined with demographic data was analyzed for any relationships. Although no statistically significant findings were established, many important trends …

Use Of The Ketogenic Diet In The Neonatal Intensive Care Unit-Safety And Tolerability., Lindsey M. Thompson, Erin Day Fecske, Mohammad Salim, Ara Hall

Manuscripts, Articles, Book Chapters and Other Papers

Drug-resistant epilepsy poses a challenge in neonatal patients, especially those in the neonatal intensive care unit (NICU), who have various secondary comorbidities. We present results of four children with a history of drug-resistant epilepsy for whom a ketogenic diet was initiated and used in the NICU. A nonfasting induction into ketosis over 1-2 weeks was utilized, with gradual increases in the ketogenic ratio every 2-3 days. Data were collected retrospectively from a database, which included medical history, daily progress notes, relevant laboratory data, and imaging and diagnostic information. The ketogenic diet was well tolerated in all cases. The most common …

Herpes Simplex Virus Type Ii In A Patient Having Periodic Lateralized Epileptiform Discharges, Justin Chuang, Sona K. Shah

Marshall Journal of Medicine

Herpes Simplex Encephalitis has been found to be one of the most common causes of fatal viral encephalitis (1). The mortality rate in untreated patients has been found to be as high as 70%, thus, correct management and early diagnosis are important for good prognoses and crucial for predicting outcomes. (1,2) In patients with Herpes Simplex Virus (HSV), specific findings such as the Periodic lateralized epileptic form discharges (PLEDs) are considered a specific finding on electroencephalogram (EEG). PLEDs are usually seen in the context of destructive structural lesions involving the cortex. Other causes may include acute ischemic stroke and, less …
