Molecular Mechanisms Of Opioid Use Disorder In Human Brain Models, Emily Mendez
Molecular Mechanisms Of Opioid Use Disorder In Human Brain Models, Emily Mendez
Dissertations & Theses (Open Access)
Opioid use disorder (OUD) is a national and global public health crisis with no end in sight. While studies from animal models hint at widespread epigenetic and transcriptomic alterations of opioid drugs, the molecular consequences of long-term exposure to opioid drugs in human brain is still unclear, and human-centered translational models are necessary to discern the human cell type-specific effects of OUD.
Using postmortem brain Brodmann area 9 (BA9) from the UTHealth Brain Collection for Research on Psychiatric Disorders, I identified angiogenic gene networks perturbed in the RNA and protein of OUD subjects, as well as downregulation of many neuron-correlated …
Single Case Experimental Design Examining Cognitive Behavioural Therapy For Post-Stroke Depression, Liam Alexander Mackenzie Myles, Emma Jones
Single Case Experimental Design Examining Cognitive Behavioural Therapy For Post-Stroke Depression, Liam Alexander Mackenzie Myles, Emma Jones
Journal of Mind and Medical Sciences
Background. Post-stroke depression (PSD) is common in older-age adults and is typically treated with cognitive-behavioural therapy (CBT). However, research has ascertained mixed findings regarding the efficacy of CBT for PSD in older-age adults, with limited evidence in people from global majority backgrounds. Materials and Methods. This case study used single case experimental design methodology to examine the effectiveness of CBT for PSD in a black, older-age man. The effects of health conditions, cohort beliefs, transitions in role investments, socio-cultural context and early experiences on the client’s thoughts, emotions, physical sensations and behaviours were formulated, before behavioural activation was used to …
Gamma-Aminobutyric Acid (Gaba) Neurons And Perineuronal Nets (Pnn) In The Monodelphis Domestica And Relevance To Psychiatric Disorders, Jatziry Z. Luna Escobedo, Mariela Garcia, John L. Vandeberg, Mario Gil
Gamma-Aminobutyric Acid (Gaba) Neurons And Perineuronal Nets (Pnn) In The Monodelphis Domestica And Relevance To Psychiatric Disorders, Jatziry Z. Luna Escobedo, Mariela Garcia, John L. Vandeberg, Mario Gil
Research Symposium
Background/ Purpose: Gamma-aminobutyric acid (GABA) is an amino acid that serves as the central nervous system’s (CNS) main inhibitory neurotransmitter. By inhibiting nerve transmission, it works to lower neuronal excitability. Altered GABA levels have been associated with a variety of psychiatric disorders, for example Epilepsies, Parkinson’s Disease, and Schizophrenia. Perineuronal nets (PNN) are extracellular molecules that are released by neurons and glial cells that modulate many neuronal and glial functions by encapsulating the inhibitory cells and neurites. Altered PNN levels serve as a potential trigger to synaptic imbalance. The purpose of this study is to quantify and analyze the presence, …
A Phenomenological Take On Mirror Self-Face Perception In Schizophrenia, Giovanni Pennisi
A Phenomenological Take On Mirror Self-Face Perception In Schizophrenia, Giovanni Pennisi
Journal of Mind and Medical Sciences
Studies concerning social deficits in schizophrenia has often been restrained to exploring facial recognition. Various investigations have shown that those diagnosed with schizophrenia have difficulties in perceiving the identities and emotions of those around them merely through observing their facial features. A few others have also taken into account the issue of self-face recognition in individuals with schizophrenia, finding that their capacity to associate photos or videos of their own face to themselves is hindered due to the illness. However, to my knowledge, only a few studies have so far delved into the intricacies of how individuals with schizophrenia or …

A Story Of Hope: How A Community Project Is Transforming The Lives Of Filipino Children With Intellectual And Developmental Disabilities, Lance Vincent C. Sese, Ma Celina L. Guillermo
Ateneo School of Medicine and Public Health Publications
The issue of social inequality became more prevalent during the pandemic and with it, the call for preferential option toward the vulnerable. 1 Not only do we protect them from sickness and death, but we are also called to improve their quality of life. Thus, it is imperative that in this call for inclusivity, we address the gap, one group at a time—for example, children with special needs. The project discussed in this perspective article exemplifies the importance of collaboration in bridging the gap to create a more holistic environment for Filipino children with special needs. This article then serves …
Data-Driven Neuroanatomical Subtypes In Various Stages Of Schizophrenia: Linking Cortical Thickness, Glutamate, And Language Functioning, Liangbing Liang
Data-Driven Neuroanatomical Subtypes In Various Stages Of Schizophrenia: Linking Cortical Thickness, Glutamate, And Language Functioning, Liangbing Liang
Electronic Thesis and Dissertation Repository
The considerable variation in the spatial distribution of cortical thickness changes has been used to parse heterogeneity in schizophrenia. We aimed to recover a ‘cortical impoverishment’ subgroup with widespread cortical thinning. We applied hierarchical cluster analysis to cortical thickness data of three datasets in different stages of psychosis and studied the cognitive, functional, neurochemical, language and symptom profiles of the observed subgroups. Our consensus-based clustering procedure consistently produced a subgroup characterized by significantly lower cortical thickness. This ‘cortical impoverishment’ subgroup was associated with a higher symptom burden in a clinically stable sample and higher glutamate levels with language impairments in …

Living With Brain Cancer: From Researcher To Patient, Stephen P. Chelko, Daniel L. Fay Ph.D.
Patient Experience Journal
As an academic researcher, my work-life revolves around testing the efficaciousness of pharmaceutical drugs on the prevention of cardiac dysfunction, arrhythmias, and sudden cardiac death in animal models of heart disease. I never thought I would go from someone studying a life-threatening disease to a patient living with one in twenty-four hours. Yet, that transformation occurred October 8, 2019. I was just appointed to Assistant Professor at Johns Hopkins University School of Medicine (JHUSOM), yet after sitting for my professional headshot I had a grand mal seizure. I cannot recall this event, but I bit the tip of my tongue …
Epigenetic Pathogenesis Of Neurological Disorders In Utero And Considerations For Genetic Counseling, Lauren Juga
Epigenetic Pathogenesis Of Neurological Disorders In Utero And Considerations For Genetic Counseling, Lauren Juga
Senior Honors Theses
Epigenetic modifications are a major focus of study in the pathogenesis of many disorders regarding metabolism, aging, neurodevelopment, and neurodegeneration. Epigenetic mechanisms are present throughout life but are especially vital to guiding fetal development. The precise timing of gene activation and deactivation guides stem cell differentiation through each embryonic stage. After exposure to environmental stimuli, gene expression can be altered by transcription factors, resulting in observable phenotypes and even pathology. Here, the epigenetic mechanisms responsible for the pathogenesis of neurodevelopmental and neuropsychiatric disorders are explored in response to environmental perturbations in utero. The present goal is to identify correlations between …
Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley
Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley
LSU Doctoral Dissertations
Post-traumatic stress disorder (PTSD) is associated with elevated allostatic load, nearly double the risk for metabolic syndrome, reduced hippocampal volume, and contextual memory processing deficits. Emerging evidence suggests that these stress effects may predispose individuals to the development of PTSD, and there is a known relationship between chronic stress and metabolic dysfunction. In this work, we utilized two rat models of PTSD to explore these connections. We used an acute predator odor stressor to investigate the relationship between PTSD-like behaviors and mitochondrial dysfunction in the hippocampus of rats, and we observed that conditioned place avoidance was associated with reduced mitochondrial …
A Study Of Limited Bedding And Nesting On Maternal Behavior For Postpartum Depression, Emma Brezoczky
A Study Of Limited Bedding And Nesting On Maternal Behavior For Postpartum Depression, Emma Brezoczky
CMC Senior Theses
Postpartum depression (PPD) affects up to 20% of mothers in the US and can detrimentally affect both the mother and psychosocial development of the child (Pearlstein et al, 2009). So far, research on PPD is limited and the underlying neuropathology remains unclear. Low socioeconomic status is one risk factor that increases the risk of PPD tenfold (Goyal et al, 2010). The low resource limited bedding and nesting (LBN) paradigm used for rodents has the potential to model this risk factor. LBN has not previously been studied with PPD, but observations of disrupted maternal behaviors and depressive phenotypes makes it a …

Background:Elucidating associations between exposures to ambient air pollutants and profiles of cognitive performance may provide insight into neurotoxic effects on the aging brain. Objective:We examined associations between empirically derived profiles of cognitive performance and residential concentrations of particulate matter of aerodynamic diameter < 2.5 (PM2.5) and nitrogen dioxide (NO2) in older women. Method:Women (N = 2,142) from the Women’s Health Initiative Study of Cognitive Aging completed a neuropsychological assessment measuring attention, visuospatial, language, and episodic memory abilities. Average yearly concentrations of PM2.5 and NO2 were estimated at the participant’s addresses for the 3 years prior to the assessment. Latent profile structural equation models identified subgroups of women exhibiting similar profiles across tests. Multinomial regressions examined associations between exposures and latent profile classification, controlling for covariates. Result:Five latent profiles were identified: low performance across multiple domains (poor multi-domain; n = 282;13%), relatively poor verbal episodic memory (poor memory; n = 216; 10%), average performance across all domains (average multi-domain; n = 974; 45%), superior memory (n = 381; 18%), and superior attention (n = 332; 15%). Using women with average cognitive ability as the referent, higher PM2.5 (per interquartile range [IQR] = 3.64μg/m3) was associated with greater odds of being classified in the poor memory (OR = 1.29; 95% Confidence Interval [CI] = 1.10–1.52) or superior attention (OR = 1.30; 95% CI = 1.10–1.53) profiles. NO2 (per IQR = 9.86 ppb) was associated with higher odds of being classified in the poor memory (OR = 1.38; 95% CI = 1.17–1.63) and lower odds of being classified with superior memory (OR = 0.81; 95% CI = 0.67–0.97). Conclusion:Exposure to PM2.5 and NO2 are associated with patterns of cognitive performance characterized by worse verbal episodic memory relative to performance in other domains.
Investigating Gene-Environment Interaction In A Double-Hit Model For Autism Spectrum Disorder, Melvin Maroon
Investigating Gene-Environment Interaction In A Double-Hit Model For Autism Spectrum Disorder, Melvin Maroon
Undergraduate Student Research Internships Conference
With the exponential advancements seen in the field of sequencing technology, the science community has come to identify hundreds of potential genetic risk factors for neuropsychiatric disorders. Despite our knowledge that such risk factors exist, we have yet to understand their specific influences on the behavioral profile of an individual. In addition, maternal infection during pregnancy can have longstanding detrimental outcomes on a child’s development. This is especially impactful with the present threat of viral infection during the pandemic. Our study aims to understand the influence of a specific genetic and environmental factor on a preclinical rodent model’s behavioral development. …

Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar
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.
Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders
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 …
Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen O'Donnell
Scope Of Attention Variation As A Function Of Anxiety And Depression, Kathleen O'Donnell
Electronic Theses, Projects, and Dissertations
As a social species, correct emotional perception is so vital, that the human brain has evolved a mechanism to control attentional choices by exerting a narrowed field of perception during danger, called the scope of attention (SoA). The SoA determines what information will be focused on or ignored by blocking the perception of non-relevant items and increasing selective focus on danger; even if danger is merely a sad-face. The emotional items blocked from perception cannot be remembered because they were never perceived. But, attention-control to emotional stimuli also varies with mood, as seen in mood-disorders. A mood-disorder’s effect upon the …

Acute Disseminated Encephalomyelitis, Ashan Hatharasinghe, Hossein Akhondi, Don Pepito
HCA Healthcare Journal of Medicine
Introduction: Acute Disseminated Encephalomyelitis (ADEM) is a rare autoimmune demyelinating disorder of the central nervous system. Clinical manifestations include encephalopathy, motor deficits, ataxia, and meningeal signs. In most cases, ADEM is preceded by either vaccination or viral illness. Here, we present a case with neither of the two predisposing elements.

Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Dissertations and Theses
In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …

Memantine: Can It Be Used To Treat Children With Autism Spectrum Disorder?, Austin Brown, Katherine Liu, Pul Lee, Rachel Muhlenkamp, Manoranjan D'Souza
Pharmacy and Wellness Review
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairment in social, behavior and communicative skills. The current therapy for ASD only targets the associated symptoms such as aggression, self-harming acts or temper tantrums but not the core symptoms of social dysfunction. The pathology of ASD is not fully understood. Interestingly, imaging studies in ASD patients have reported abnormal high levels of glutamate in certain brain regions that play an important role in social interaction and communication. Thus, it has been hypothesized that medications attenuating glutamate transmission may be used as treatment for some of the core symptoms of …
Probiotic Administration As An Adjuvant Therapeutic Treatment For Anxiety, Depression, And Cognitive Impairment Among Hypothyroid Patients, Erin R. Gorman
Probiotic Administration As An Adjuvant Therapeutic Treatment For Anxiety, Depression, And Cognitive Impairment Among Hypothyroid Patients, Erin R. Gorman
Selected Honors Theses
Hypothyroidism is a form of thyroid dysfunction that occurs when the thyroid gland does not make and secrete enough thyroid hormones to regulate certain processes in the body. Because thyroid hormones take part in many bodily functions, hypothyroidism can cause a large range of symptoms. Current research indicates that some strains of probiotics have beneficial effects on certain neurological and inflammatory diseases, leading to the impression that they can be used therapeutically for effective treatment of different mental health issues such as anxiety, stress, depression, and impaired memory. Because hypothyroidism often leads to such mental symptoms, it may be possible …
White Matter Inflammation And Executive Dysfunction: Implications For Alzheimer Disease And Vascular Cognitive Impairment, Alexander Levit
White Matter Inflammation And Executive Dysfunction: Implications For Alzheimer Disease And Vascular Cognitive Impairment, Alexander Levit
Electronic Thesis and Dissertation Repository
White matter integrity is crucial to healthy executive function, the cognitive domain that enables functional independence. However, in the ageing brain, white matter is highly vulnerable. White matter inflammation increases with age and Alzheimer disease (AD), which disrupts the normal function of white matter. This may contribute to executive dysfunction, but the relationship between white matter inflammation and executive function has not been directly evaluated in ageing nor AD. White matter is also particularly vulnerable to cerebrovascular disease, corresponding with the common presentation of executive dysfunction in vascular cognitive impairment (VCI). Thus, white matter may be an important substrate by …
Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia
Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia
Dissertations, Theses, and Capstone Projects
Current developmental models of gender identity and gender dysphoria (GD) lack sex-specific profiles of brain function that differentiate between typically-developing and cross-gender identified youth, as postulated by models like the unified theory of the origins of sex differences (Arnold, 2009) and the neurobiological theory of the origins of transsexuality (Swaab & Garcia-Falgueras, 2009). Previously, investigators have used brain imaging modalities such as Resting-State functional Magnetic Resonance Imaging (R-fMRI) to demonstrate differences in resting-state functional connectivity (RSFC) between typically-developing male and female youth, and between typically-developing and GID-diagnosed youth. In the present pilot study, I used R-fMRI to investigate differences in …

The Mind-Body Problem; Three Equations And One Solution Represented By Immaterial-Material Data, Ion G. Motofei, David L. Rowland
Journal of Mind and Medical Sciences
Human life occurs within a complex bio-psycho-social milieu, a heterogeneous system that is integrated by multiple bidirectional interrelations existing between the abstract-intangible ideas and physical-chemical support of environment. The mind is thus placed between the abstract ideas/ concepts and neurobiological brain that is further connected to environment. In other words, the mind acts as an interface between the immaterial (abstract/ intangible) data and material (biological) support. The science is unable to conceives and explains an interaction between the immaterial and material domains (to understand nature of the mind), this question generating in literature the mind-body problem. We have published in …
Cortical Thinning And Neuropsychiatric Outcomes In Children Exposed To Prenatal Adversity: A Role For Placental Crh?, Curt A. Sandman, Megan M. Curran, Elyssia Poggi Davis, Laura M. Glynn, Kevin Head, Tallie Z. Baram
Cortical Thinning And Neuropsychiatric Outcomes In Children Exposed To Prenatal Adversity: A Role For Placental Crh?, Curt A. Sandman, Megan M. Curran, Elyssia Poggi Davis, Laura M. Glynn, Kevin Head, Tallie Z. Baram
Psychology Faculty Articles and Research
Exposure to early life adversity may disrupt the development and maturation of neurons and brain circuits, which, in turn, underlie neurodevelopment and mental illnesses. During fetal life, maternal adversity is conveyed to the developing brain via several molecular signals, including the stress hormone corticotropin releasing hormone (CRH). Employing a large well characterized prospective cohort, we find that fetal exposure to placental-origin CRH levels predicts structural and functional brain outcomes in children. Specifically, elevated placental CRH levels portend thinning of selective cortical regions of exposed individuals, with commensurate cognitive and emotional deficits. Notably, the relations of placental-origin CRH to cortical thinning …

The overall prevalence of MetS was 14.1%, 20.4%, and 23.6% using NCEP ATP III, WHO, and IDF criteria, respectively, compared to 7.8%, 3.9%, and 2.2% reported in the generalGhanaian population.The prevalence …
Neuronal Correlates For Neuroendocrine Habituation To Repeated Stress, Sara Matovic
Neuronal Correlates For Neuroendocrine Habituation To Repeated Stress, Sara Matovic
Electronic Thesis and Dissertation Repository
One way that the body actively responds to an impending stressor is by increasing systemic glucocorticoids through the activation of the hypothalamic-pituitary-adrenal (HPA) axis. While it is essential for short-term adaptation to stress, the sustained activation of the HPA axis during chronic stress can be detrimental and is linked to stress-related psychiatric conditions such as anxiety and depression. Therefore, it is important that the HPA axis adapts, or habituates, during chronic stress to minimize the negative consequences. Corticotropin releasing hormone (CRH) neurons in the paraventricular nucleus of the hypothalamus (PVN) function to assimilate incoming information from the stress circuitry and …
The Psychology Of Neurofeedback: Clinical Intervention Even If Applied Placebo, Robert T. Thibault, Amir Raz
The Psychology Of Neurofeedback: Clinical Intervention Even If Applied Placebo, Robert T. Thibault, Amir Raz
Psychology Faculty Articles and Research
Advocates of neurofeedback make bold claims concerning brain regulation, treatment of disorders, and mental health. Decades of research and thousands of peer-reviewed publications support neurofeedback using electroencephalography (EEG-nf); yet, few experiments isolate the act of receiving feedback from a specific brain signal as a necessary precursor to obtain the purported benefits. Moreover, while psychosocial parameters including participant motivation and expectation, rather than neurobiological substrates, seem to fuel clinical improvement across a wide range of disorders, for-profit clinics continue to sprout across North America and Europe. Here, we highlight the tenuous evidence supporting EEG-nf and sketch out the weaknesses of this …
Mindfulness And Law Enforcement: An Effective Approach To Implementing Mindfulness For First Responders, Gina White
Mindfulness And Law Enforcement: An Effective Approach To Implementing Mindfulness For First Responders, Gina White
Mindfulness Studies Theses
An increasing number of studies show that people employed as first responders in high trauma service jobs tend to experience a high level of stress, at work and after hours. Studies suggest that constant exposure to job related stress leads to both physical and mental dysregulation. This study looks at the effects of implementing mindfulness tools and techniques to those working in law enforcement. Other works on this topic report mindfulness as a successful tool to increase wellbeing to a broad spectrum of populations. The methodology used in this study was designed specifically for first responders. The data findings were …
Acetaminophen Associated Neurotoxicity And Its Relevance To Neurodevelopmental Disorders, Seol-Hee Kim
Acetaminophen Associated Neurotoxicity And Its Relevance To Neurodevelopmental Disorders, Seol-Hee Kim
USF Tampa Graduate Theses and Dissertations
Autism is a lifelong neurodevelopmental disorder. The etiology of autism still remains unclear due to the heterogeneous and complex nature of the disorder, however synergistic actions between genetic components and environmental factors have been suggested. Acetaminophen (APAP) is one of the most popular over-the-counter drugs that possess antipyretic and analgesic effects. It is considered a relatively safe and effective within therapeutic doses. Recently, early exposure to APAP has been suggested to be one of the underlying cause of autism. Children are often prescribed APAP to lessen fever or irritability after vaccination during the first year, and APAP may adversely affect …
