Investigating The Mammillary Bodies As An Early Target Of Alzheimer's Disease, Cole Martinson

University Honors Theses

Alzheimer's disease (AD) is the most common form of dementia. With minimal treatment options and no cure, developing a deeper understanding of the pathology of the disease is crucial. For nearly four decades, the accumulation of beta-amyloid (Aβ) plaques has been correlated with the disease and its progression. Previous studies mapping this accumulation show that the mammillary bodies (MB) are an early target of the disease. Glutamatergic neurons are of key interest due to their prevalence in the central nervous system, specifically the MB. To understand the effects of AD on the glutamatergic system, we used vesicular glutamate transporter 2 …

Microrna (Mirna) Complexity In Alzheimer’S Disease (Ad), Walter J. Lukiw

School of Medicine Faculty Publications

AD is a complex, progressive, age-related neurodegenerative disorder representing the most common cause of senile dementia and neurological dysfunction in our elderly domestic population. The widely observed heterogeneity of AD is a reflection of the complexity of the AD process itself and the altered molecular-genetic mechanisms operating in the diseased human brain and CNS. One of the key players in this complex regulation of gene expression in human pathological neurobiology are microRNAs (miRNAs) that, through their actions, shape the transcriptome of brain cells that normally associate with very high rates of genetic activity, gene transcription and messenger RNA (mRNA) generation. …

Alcohol As A Modifiable Risk Factor For Alzheimer’S Disease—Evidence From Experimental Studies, Devaraj V. Chandrashekar, Ross A. Steinberg, Derick Han, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Alzheimer’s disease (AD) is a progressive neurodegenerative disease characterized by cognitive impairment and memory loss. Epidemiological evidence suggests that heavy alcohol consumption aggravates AD pathology, whereas low alcohol intake may be protective. However, these observations have been inconsistent, and because of methodological discrepancies, the findings remain controversial. Alcohol-feeding studies in AD mice support the notion that high alcohol intake promotes AD, while also hinting that low alcohol doses may be protective against AD. Chronic alcohol feeding to AD mice that delivers alcohol doses sufficient to cause liver injury largely promotes and accelerates AD pathology. The mechanisms by which alcohol can …

The Role Of Extracellular Heat Shock Proteins In Cardiovascular Diseases, Soumya Patnaik, Sriram Nathan, Biswajit Kar, Igor D Gregoric, Yi-Ping Li

Faculty, Staff and Student Publications

In the early 1960s, heat shock proteins (HSPs) were first identified as vital intracellular proteinaceous components that help in stress physiology and reprogram the cellular responses to enable the organism's survival. By the early 1990s, HSPs were detected in extracellular spaces and found to activate gamma-delta T-lymphocytes. Subsequent investigations identified their association with varied disease conditions, including autoimmune disorders, diabetes, cancer, hepatic, pancreatic, and renal disorders, and cachexia. In cardiology, extracellular HSPs play a definite, but still unclear, role in atherosclerosis, acute coronary syndromes, and heart failure. The possibility of HSP-targeted novel molecular therapeutics has generated much interest and hope …

Gm1 Ganglioside As A Disease-Modifying Therapeutic For Parkinson’S Disease: A Multi-Functional Glycosphingolipid That Targets Multiple Parkinson’S Disease-Relevant Pathogenic Mechanisms, Jay S. Schneider

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Parkinson’s disease (PD) is a progressive neurodegenerative disorder affecting millions of patients worldwide. Many therapeutics are available for treating PD symptoms but there is no disease-modifying therapeutic that has been unequivocally shown to slow or stop the progression of the disease. There are several factors contributing to the failure of many putative disease-modifying agents in clinical trials and these include the choice of patients and clinical trial designs for disease modification trials. Perhaps more important, however, is the choice of therapeutic, which for the most part, has not taken into account the multiple and complex pathogenic mechanisms and processes involved …

Exploring The Hinterland: The Development Of A Person-Centered Music Therapy Method For A Hospice Patient With Lewy Body Dementia, Paige Chaplin

Expressive Therapies Capstone Theses

This thesis explores the development and implementation of a music therapy method with an individual diagnosed with dementia with Lewy Bodies (DLB) receiving home hospice services. There is very little known about the effect of music therapy on patients diagnosed with DLB. Informed by Tom Kitwood’s Person-Centered Care (PCC) philosophy for dementia care, Yumiko Sato’s Musical Life Review (MLR) model, and Lisa Kelly and Bill Ahessy’s Reminiscence-Focused Music Therapy (RFMT) model, a clinical method was developed to explore the effects of person-centered music therapy on reminiscence, caregiver connection, and identity. I drew inspiration from music therapy concepts by Tony Wigram …

Dextromethorphan/Quinidine For The Pseudobulbar Affect In Neurological Disorders And Injuries: Systematic Review And Meta-Analysis, Magnolia Livingston

Honors Theses

AVP-923, commonly known as Nuedexta or Zenvia, is a drug that has recently been suggested as a potential treatment for Pseudobulbar Affect in patients affected by different neurological disorders and injuries. Studies have been done to examine the effectiveness of AVP-923 on PBA, but the results of these studies don’t seem to be comparable. The goal of this meta-analysis is to assess the efficacy and safety of AVP-923. 781 individuals from six trials were included in the analysis. The analysis's findings revealed that AVP-923 considerably lowered the Center for Neurological Study Lability Scale (CNS-LS) scores and the frequency and severity …

Ghilardi, John-Ross Rizzo

Department of Exercise Science Faculty Papers

Introduction: Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease. Complementary and alternative therapies are increasingly utilized to address its complex multisystem symptomatology. Art therapy involves motoric action and visuospatial processing while promoting broad biopsychosocial wellness. The process involves hedonic absorption, which provides an escape from otherwise persistent and cumulative PD symptoms, refreshing internal resources. It involves the expression in nonverbal form of multilayered psychological and somatic phenomena; once these are externalized in a symbolic arts medium, they can be explored, understood, integrated, and reorganized through verbal dialogue, effecting relief and positive change.

Identifying The Neural Correlates Of Anticipatory Postural Control: A Novel Fmri Paradigm, Jo Armour Smith, Rongwen Tain, Kelli G. Sharp, Laura M. Glynn, Linda R. Van Dillen, Korinne Henslee, Jesse V. Jacobs, Steven C. Cramer

Physical Therapy Faculty Articles and Research

Altered postural control in the trunk/hip musculature is a characteristic of multiple neurological and musculoskeletal conditions. Previously it was not possible to determine if altered cortical and subcortical sensorimotor brain activation underlies impairments in postural control. This study used a novel fMRI-compatible paradigm to identify the brain activation associated with postural control in the trunk and hip musculature. BOLD fMRI imaging was conducted as participants performed two versions of a lower limb task involving lifting the left leg to touch the foot to a target. For the supported leg raise (SLR) the leg is raised from the knee while the …

Study Of The Potential Toxicity Of Adrenaline To Neurons, Using The Sh-Sy5y Human Cellular Model, Vera Marisa Costa, João Paulo Capela, Maria Lourdes Bastos, Fernando Remião, Kurt James Varner, José Alberto Duarte, Félix Carvalho

School of Graduate Studies Faculty Publications

Prolonged overexposure to catecholamines causes toxicity, usually credited to continuous adrenoceptor stimulation, autoxidation, and the formation of reactive pro-oxidant species. Non-differentiated SH-SY5Y cells were used to study the possible contribution of oxidative stress in adrenaline (ADR)-induced neurotoxicity, as a model to predict the toxicity of this catecholamine to peripheral nerves. Cells were exposed to several concentrations of ADR (0.1, 0.25, 0.5 and 1mM) and two cytotoxicity assays [lactate dehydrogenase (LDH) release and 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyl tetrazolium bromide (MTT) reduction] were performed at several time-points (24, 48, and 96h). The cytotoxicity of ADR was concentration-and time-dependent in both assays, since the lowest concentration …

Differential Degeneration Of Neurons In A Mouse Model Of Canavan Disease, Vibha Chauhan, Quy Nguyen, Jeremy Francis, Paola Leone

Rowan-Virtua Research Day

Canavan disease (CD) is an inherited leukodystrophy caused by inactivating mutations to the glial enzyme aspartoacylase (ASPA). ASPA catabolizes neuronal N-acetylaspartate (NAA) into free acetate and aspartate and loss of this function results in the chronic elevation of non-catabolized NAA and the failure of developmental myelination. Elevated NAA is thought to cause damage to myelin and myelin-producing cells (oligodendrocytes, but the viability of neurons in CD is relatively unexplored. We compare here the progressive degeneration of neurons in two regions of the CD mouse brain, the thalamus and the cortex, distinguished by differing degrees of vacuolation, and show that the …

Obstructive Hydrocephalus Caused By A Colloid Cyst Presenting As A Transient Ischemic Attack (Tia), Muhammad Nadeem

Rowan-Virtua Research Day

Colloid cysts are benign growths commonly found in the third ventricle or at the Foramen of Monroe. They are composed of epithelial lining filled with gelatinous material that contain cholesterol, mucin, old blood and ions. Most colloid cysts are asymptomatic but can present with a variety of symptoms that range from headaches, diplopia, memory problems, and vertigo. They can also present as an obstructive hydrocephalus with the classic “Wet, wacky and wobbly” triad. Rarely colloid cysts have been reported to cause sudden death. They can present to the ED with any spectrum of these symptoms.

Swallowing Disrupts Tongue-Jaw Coordination During Chewing In A Rat Model Of Parkinson's Disease, Meejan Palhang, N. Charles, Francois Gould

Rowan-Virtua Research Day

The primary motor symptoms of Parkinson’s disease, including bradykinesia, rigidity, and tremor, are associated with difficulties regulating transitions between motor behaviors due to basal ganglia dysfunction. Chewing and swallowing, which are disordered in most patients with Parkinson’s disease, are two complex motor behaviors which overlap in time and share some neuromuscular components. The objective of this study is to identify how Parkinson’s disease affects the coordination of chewing and swallowing. We hypothesize that as a result of impaired regulation of shift between motor patterns, chewing cycles that occur with a swallow will be more affected that chewing cycles occurring in …

Mesenchymal Stem Cell Therapy For Amyotrophic Lateral Sclerosis, Vrushank Shah, Usmaan Al-Shehab, Keyur Patel, Alexander King

Rowan-Virtua Research Day

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig disease, is a fatal neurodegenerative disease affecting motor neurons in the brain and spinal cord. Progressive muscle weakness, atrophy, and spasticity characterize the condition, which eventually leads to paralysis and respiratory failure. There is currently no cure for ALS, and the standard of care is supportive, with riluzole being the only approved medication that has been shown to slightly slow disease progression (1).

However, the use of mesenchymal stem cells (MSCs) in the treatment of ALS is a new area of research in regenerative medicine. MSCs are multipotent stem cells that …
