Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

Neural Correlates Of Recognition Memory And Metamemory In Breast Cancer Survivors: An Event-Related Potential Study, Dishari Zaman Azad

Dissertations, Theses, and Capstone Projects

Breast cancer survivors (BCS) often report noticeable cognitive difficulties despite showing limited impairment on standardized neuropsychological tests. Some have theorized that this is simply an insensitivity of standardized testing to subtle cognitive changes (test-insensitivity hypothesis), whereas others have suggested there are early neural changes that are detected by patients but precede detection by these tests (early signal hypothesis) or that when they achieve normal performance, it is through saliently effortful compensatory processes (compensation hypothesis). The present study tested these theories by assessing metamemory and recognition memory retrieval in BCS and non-cancer controls (NCC) using both behavioral and event-related potential (ERP) …

Improved Model For Neurodegeneration In C. Elegans, Jean-Pierre Arditi

Graduate Theses and Dissertations (2019 - present)

During Alzheimer's disease (AD), insoluble amyloid beta (AP) peptides accumulate to form extracellular aggregates (plaques). The direct cause of neuronal dysfunction observed in AD has been broadly investigated. The amyloid hypothesis states that AP plaques are neurotoxic, but recent studies support the AP oligomer hypothesis, which states that intracellular AP (iAP) is neurotoxic. To test this hypothesis, I used CRISPR-Cas9 gene editing to generate two transgenic Caenorhabditis elegans (C. elegans) strains. I generated a strain (RSLl 11) using the rab-3 promoter to co-express GFP in neurons, which showed no gross behavioral changes but had a 50% reduced egglaying rate. RSLl …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

School of Medicine Faculty Publications

Background: Parkinson’s Disease (PD) can include physical signs and possibly cognitive impairment, resulting from the convergence of pathologicalprocesses involving dopaminergic dysfunction, accumulation ofalpha-synuclein, cholinergic deficits, and disruption of otherneurotransmitter systems. We used screening tests to evaluate thecharacteristics of cognitive performance in patients with PD and to assess their validity compared tothe Montreal Cognitive Assessment (MoCA). Methods: This is a natural history study of participants with PD and controls screened for possible cognitive impairment using the MoCA, Symbol Digit Modalities Test (SDMT), and King-Devick (KD). The groups were compared on performance and then factors associated with cognitive performance (age, diagnosis, and …

Effects Of Social Isolation On Cecum Opioid Receptor Expression And Affective Behavior, Jordan Riser, John Tkaczynski, Nicole Shellenbarger, Maya Patel, Daniel Chandler, Daniel Manvich

Rowan-Virtua Research Day

BACKGROUND

Psychological stress can induce gastrointestinal symptoms and exacerbate existing gastrointestinal disorders, indicating an interaction between the central and enteric nervous systems. Central nervous system activation of opioid receptors stimulates sympathetic outflow to the enteric nervous system, delaying motility and reducing gastrointestinal secretions, producing a similar clinical presentation to IBS.

HYPOTHESIS

We hypothesize that social isolation induces anxiety states, disrupting homeostatic noradrenergic activity in the brain and gut, leading to neurophysiological changes in the cecum characterized by altered expression of opioid receptors.

METHODS

Sprague-Dawley rats were housed in either group (control) or socially isolated conditions. Affective behavior was assessed using …

Weighted Family History Density Of Substance Use: Influence On Participant Substance Use Onset, Escalation, And Duration, Carleigh A. Litteral

Theses and Dissertations--Psychology

Substance use disorders impose a staggering toll on the United States (U.S.), straining healthcare systems, destabilizing communities, and profoundly impacting both individuals and families. Approximately one in six Americans aged 12 and older had a past-year substance use disorder in 2022 (Key Substance Use, 2022), and nearly one-third of adults experience a substance use disorder in their lifetime (Wu, 2010), contributing to an economic burden exceeding $400 billion annually (National Drug Threat Assessment, 2011). Family history of substance use disorders is a key predictor of vulnerability, with individuals who have affected relatives being 2–8 times more …

Medial Prefrontal Cortex To Nucleus Reuniens Circuit Is Critical For Performance In An Operant Delayed Nonmatch To Position Task, Evan J Ciacciarelli, Scott D Dunn, Taqdees Gohar, T Joseph Sloand, Mark Niedringhaus, Elizabeth A West

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Working memory refers to the temporary retention of a small amount of information used in the execution of a cognitive task. The prefrontal cortex and its connections with thalamic subregions are thought to mediate specific aspects of working memory, including engaging with the hippocampus to mediate memory retrieval. We used an operant delayed-non match to position task, which does not require the hippocampus, to determine roles of the rodent medial prefrontal cortex (mPFC), the nucleus reuniens thalamic region (RE), and their connection. We found that transient inactivation of the mPFC and RE using the GABA-A agonist muscimol led to a …

Memory Modulation: Dominance Of Negative Visual Context Over Neutral Verbal Memory, Stas Kozak, Noa Herz, Maya Tocker, Yair Bar-Haim, Nitzan Censor

Department of Neurology Faculty Papers

Neutral memories can be modulated via intentional memory control paradigms such as directed forgetting. In addition, previous studies have shown that neutral visual memories can be modulated indirectly, via remember and forget instructions towards competing verbal memories. Here we show that direct modulation of neutral verbal memory strength is impaired by negative visual context, and that negative visual context is resistant to indirect memory modulation. Participants were directly instructed to intentionally remember or forget newly encoded neutral verbal information. Importantly, this verbal information was interleaved with embedded negative visual context. Results showed that negative visual context eliminated the well-documented effect …

Regression models investigated associations between DANA task digital measures and a neuropsychological global cognitive

CONCLUSIONS: Our findings demonstrate that smartphone-based cognitive assessments exhibit concurrent validity with a …

Cancer Research Provides A Model For Advancing Clinical Trials In Dementia In The Era Of Disease-Modifying Alzheimer’S-Type Dementia Therapies, Gregory Jicha, Thomas Tucker, Susanne Arnold, Peter T. Nelson

Neurology Faculty Publications

Dementia and cancer are multifactorial, widely-feared, age-associated clinical syndromes that are increasing in prevalence. There have been major breakthroughs in clinical cancer research leading to some effective treatments, whereas the field of dementia has achieved comparatively limited success in clinical research. The lessons of cancer research may help those in the dementia research field in confronting some of the dilemmas faced when the clinical care regimen is not entirely safe or efficacious. Cancer clinical trials have assumed that untreated individuals with cancer are at high risk for morbidity and mortality after primary diagnoses. Thus, patients deserve a choice of clinical …

Early intervention in Alzheimer's is vital for treatment. The earlier a professional can detect symptoms and make a diagnosis the earlier a prognosis can be implemented. With the prevalence of data in our day-to-day world combined with Artificial intelligence (AI), utilizing both for machine learning can pave the way for more accurate and efficient detection of Alzheimer's and other neurodegenerative diseases. AI combined with Machine learning (ML) increases diagnostic efficiency and reduces human errors, making it a valuable resource for physicians and clinicians alike. With the increasing amount of data processing and image interpretation required, the ability to use AI …

Impact Of Amyloid And Cardiometabolic Risk Factors On Prognostic Capacity Of Plasma Neurofilament Light Chain For Neurodegeneration, Keun You Kim, Eosu Kim, Jun-Young Lee, Alzheimer’S Disease Neuroimaging Initiative

Neurology Faculty Publications

Background Plasma neurofilament light chain (NfL) is a blood biomarker of neurodegeneration, including Alzheimer’s disease. However, its usefulness may be influenced by common conditions in older adults, including amyloid‑β (Aβ) deposition and cardiometabolic risk factors like hypertension, diabetes mellitus (DM), impaired kidney function, and obesity. This longitudinal observational study using the Alzheimer’s Disease Neuroimaging Initiative cohort investigated how these conditions influence the prognostic capacity of plasma NfL. Methods Non‑demented participants (cognitively unimpaired or mild cognitive impairment) underwent repeated assessments including the Alzheimer’s Disease Assessment Scale‑Cognitive subscale (ADAS‑Cog) scores, hippocampal volumes, and white matter hyperintensity (WMH) volumes at 6‑ or 12‑month …

Intellectual Disability Related To De Novo Germline Loss Of The Distal End Of The P-Arm Of Chromosome 17: A Case Report, Eden Pope, Matthew Huertas, Amar Paul, Braden Cunningham, Matthew Jennings, Ryan Perry, Stephanie Chavez, John A. Kriak, Kyle B. Bills, David W. Sant

Annual Research Symposium

Hypothesis/Purpose: In this report we present a case of a 20-year-old female with congenital intellectual disability, stunted growth, and hypothyroidism. Competitive genetic hybridization (CHG) revealed a loss of 17p13.3, and the deletion was not present in either parent. This deletion has not previously been characterized, but mutations on the p-arm of chromosome 17 are responsible for Miller-Dieker Syndrome and Isolated Lissencephaly Sequence, both of which share symptoms in common with the patient.

Methods: Peripheral mononuclear cells (PBMCs) were used for karyotyping and competitive genetic hybridization (CHG). Bioinformatic analysis was carried out using the Genome Data Viewer (ncbi.nlm.nih.gov/genome/gdv).

Results: Karyotype was …

Enhancing The Quality Of Life For Senior Citizens: A Facilitator’S Guidebook For Mindful Music And Movement, Shannon Sexton

Mindfulness Studies Theses

Music appreciation and enjoyment enhance well-being throughout the lifespan. The challenges and constraints that people experience as they age can lead to lack of access to music, decreased physical activity, and fewer avenues for creative expression. Group music and movement interventions created for older populations offer opportunities for social connection and improved quality of life. Mindful practices add further benefit when combined with these interventions. Current available programs are scarce and most often do not encompass mixed modalities. In addition, the benefits of these programs do not show long-term sustainability. The purpose of this thesis is to explore the effects …

Alzheimer's And Patient Caregiver Burnout: A Review Of The Literature, Madeline Hekeler

James Madison Undergraduate Research Journal (JMURJ)

The term “silent epidemic” is fitting for Alzheimer’s disease (AD), as its negative impact is widely felt but rarely discussed. Burnout among AD caregivers has become an epidemic of its own as caregivers experience an increase in health risks, stress, and financial burden. This literature review focuses on caregiver burnout and how imperative it is that caregivers are better supported in their role. Researchers have developed instruments to assess and intervene in caregiver burnout that have shown effectiveness among caregivers and their families.Nevertheless, further longitudinal research is warranted regarding more effective interventions, including stress management and social support mechanisms.

Mechanisms Of Memory Updating: State Dependency Vs. Reconsolidation, Christopher Kiley, Colleen M. Parks

Psychology Faculty Research

Reactivating a memory trace has been argued to put it in a fragile state where it must undergo a stabilization process known as reconsolidation. During this process, memories are thought to be susceptible to interference and can be updated with new information. In the spatial context paradigm, memory updating has been shown to occur when new information is presented in the same spatial context as old information, an effect attributed to a reconsolidation process. However, the integration concept holds that memory change can only occur when reactivation and test states are the same, similar to a state-dependent effect. Thus, in …

Apathy And Brain Atrophy During The First Year Of Moderate-Severe Traumatic Brain Injury: A Longitudinal Study, Gulnaz Kudoiarova

Dissertations, Theses, and Capstone Projects

Apathy, defined as disinterest and loss of motivation, is a common complication after moderate-severe traumatic brain injury (msTBI). The existing body of research in various neurological and neurodegenerative disorders suggests that apathetic symptoms may be associated with variation in the volume of the brain regions such as dorsal anterior cingulate cortex and ventral striatum. However, the longitudinal pattern of TBI-induced atrophy in these key regions and its relationship with apathy symptoms remain to be demonstrated. The current study aimed to describe the atrophy pattern in the anterior cingulate gyrus (ACG) and the nucleus accumbens (NAc; part of ventral striatum) after …

Developing Methods To Detect And Diagnose Chronic Traumatic Encephalopathy During Life: Rationale, Design, And Methodology For The Diagnose Cte Research Project, Jeffrey Cummings, Numerous Authors, See Full List Below

School of Medicine Faculty Research

Background: Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease that has been neuropathologically diagnosed in brain donors exposed to repetitive head impacts, including boxers and American football, soccer, ice hockey, and rugby players. CTE cannot yet be diagnosed during life. In December 2015, the National Institute of Neurological Disorders and Stroke awarded a seven-year grant (U01NS093334) to fund the “Diagnostics, Imaging, and Genetics Network for the Objective Study and Evaluation of Chronic Traumatic Encephalopathy (DIAGNOSE CTE) Research Project.” The objectives of this multicenter project are to: develop in vivo fluid and neuroimaging biomarkers for CTE; characterize its clinical presentation; refine …

Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar

Journal of Wellness

The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies.

Acute Effect Of High‑Definition And Conventional Tdcs On Exercise Performance And Psychophysiological Responses In Endurance Athletes: A Randomized Controlled Trial, Daniel Gomes Da Silva Machado, Marom Bikson, Abhishek Datta, Egas Caparelli‑Dáquer, Gozde Unal, Abrahão F. Baptista, Edilson Serpeloni Cyrino, Li Min Li, Edgard Morya, Alexandre Moreira, Alexandre Hideki Okano

Publications and Research

Transcranial direct current stimulation (tDCS) has been used aiming to boost exercise performance and inconsistent findings have been reported. One possible explanation is related to the limitations of the so-called “conventional” tDCS, which uses large rectangular electrodes, resulting in a diffuse electric field. A new tDCS technique called high-definition tDCS (HD-tDCS) has been recently developed. HD-tDCS uses small ring electrodes and produces improved focality and greater magnitude of its aftereffects. This study tested whether HD-tDCS would improve exercise performance to a greater extent than conventional tDCS. Twelve endurance athletes (29.4 ± 7.3 years; 60.15 ± 5.09 ml kg− 1 min− …

Pornography: Social, Emotional And Mental Implications Among Adolescents, William Kelly Canady

National Youth Advocacy & Resilience Conference

This presentation will explain the historical development of pornography. It will highlight four segments: 1- Porn’s impact on brain development of reward pathways, ultimately increasing the appetite for more porn. 2- Porn can be a false substitute for real intimacy, resulting in decreased sexual satisfaction with a real person and increased verbal and physical aggression. 3- Porn promotes sex trafficking, promotes multiple sex partners and reduced STD prevention. 4- A review of interventions available to assist clients in navigating a lifestyle away from pornography.

How Does Direct Volunteering Affect The Onset Of Alzheimer’S Dementia In Elderly Patients With Preexisting Cardiac Comorbidities?, Sneha R. Gade

Undergraduate Research Posters

Alzheimer's Dementia is a disease that affects memory, thinking, and behavior. The Alzheimer's Association reported Alzheimer's as the sixth-leading cause of death in the United States, and a cure does not exist. Donepezil, a cholinesterase inhibitor drug, is frequently prescribed to treat Alzheimer's disease. Still, patients must continuously take the medication for years to receive any measurable improvement in quality of life after developing Alzheimer's Dementia. Further, research shows prolonged use of Donepezil can lead to other health problems, such as QTc prolongation, for cardiac disease patients. Therefore, the effectiveness of non-drug interventions, such as volunteering to prevent the disease's …

Network-Level Mechanisms Underlying Effects Of Transcranial Direct Current Stimulation (Tdcs) On Visuomotor Learning, Pejman Sehatpour, Clément Dondé, Matthew J. Hoptman, Johanna Kreither, Devin Adair, Elisa Dias, Blair Vail, Stephanie Rohrig, Gail Silipo, Javier Lopez-Calderon, Antigona Martinez, Daniel C. Javitt

Publications and Research

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation approach in which low level currents are administered over the scalp to influence underlying brain function. Prevailing theories of tDCS focus on modulation of excitation-inhibition balance at the local stimulation location. However, network level effects are reported as well, and appear to depend upon differential underlying mechanisms. Here, we evaluated potential network-level effects of tDCS during the Serial Reaction Time Task (SRTT) using convergent EEG- and fMRI-based connectivity approaches. Motor learning manifested as a significant (p <.0001) shift from slow to fast responses and corresponded to a significant increase in beta-coherence (p <.0001) and fMRI connectivity (p <.01) particularly within the visual-motor pathway. Differential patterns of tDCS effect were observed within different parametric task versions, consistent with network models. Overall, these findings demonstrate objective physiological effects of tDCS at the network level that result in effective behavioral modulation when tDCS parameters are matched to network-level requirements of the underlying task.

Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders

Undergraduate Research Symposium

Abstract

Researchers are interested in the outcomes of interventions, specifically, measuring historical trauma (HT) among American Indian/Alaska Native communities and the long-term distress and substance abuse as a result of historical trauma response (HTR). Previous literature has implicated limitations in the clinical conceptualization of the relationship between intergenerational transfer of HTR and substance abuse. The aim of the current study is to examine treatment efficacy of 50 homosexual, American Indian males randomized to a culturally-adapted juxtaposition of (1) Group Interpersonal Psychotherapy (IPT), (2) Cognitive Processing Therapy (CPT), and (3) Historical Trauma and Unresolved Grief Intervention (HTUG), or (4) waitlisted on …

Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz

Theses

Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is a technique that is widely used for analyzing brain function using different approaches and methods. This study involves rs-fMRI analysis of Blood Oxygenation Level Dependent (BOLD) signals acquired from Alzheimer’s disease (AD) Patients and Healthy Controls (HC). Each subject in the study had both functional and anatomical images with at least one rs-fMRI scan with their Anatomical (T1) scans. Previous rs-fMRI studies have demonstrated that AD shows differences in Amplitude of Low Frequency (<0.1 Hz) Fluctuations (ALFF), and Regional Homogeneity (ReHo) measures according to HCs.

The aim of the study is to investigate individual and group level differences using ReHo and mALFF related …
