Individual Longitudinal Changes In Dna-Methylome Identify Signatures Of Early-Life Adversity And Correlate With Later Outcome, Annabel K. Short, Ryan Weber, Noriko Kamei, Christina Wilcox Thai, Hina Arora, Ali Mortazavi, Hal S. Stern, Laura M. Glynn, Tallie Z. Baram

Psychology Faculty Articles and Research

Adverse early-life experiences (ELA) affect a majority of the world's children. Whereas the enduring impact of ELA on cognitive and emotional health is established, there are no tools to predict vulnerability to ELA consequences in an individual child. Epigenetic markers including peripheral-cell DNA-methylation profiles may encode ELA and provide predictive outcome markers, yet the interindividual variance of the human genome and rapid changes in DNA methylation in childhood pose significant challenges. Hoping to mitigate these challenges we examined the relation of several ELA dimensions to DNA methylation changes and outcome using a within-subject longitudinal design and a high methylation-change threshold. …

Associations Between Stress, Health Behaviors, And Quality Of Life In Young Couples During The Transition To Survivorship: Protocol For A Measurement Burst Study, Dalnim Cho, Michael Roth, Susan K Peterson, Kristofer Jennings, Seokhun Kim, Shiao-Pei Weathers, Sairah Ahmed, J Andrew Livingston, Carlos Barcenas, Y Nancy You, Kathrin Milbury

Student and Faculty Publications

BACKGROUND: Cancer is a life-threatening, stressful event, particularly for young adults due to delays and disruptions in their developmental transitions. Cancer treatment can also cause adverse long-term effects, chronic conditions, psychological issues, and decreased quality of life (QoL) among young adults. Despite numerous health benefits of health behaviors (eg, physical activity, healthy eating, no smoking, no alcohol use, and quality sleep), young adult cancer survivors report poor health behavior profiles. Determining the associations of stress (either cancer-specific or day-to-day stress), health behaviors, and QoL as young adult survivors transition to survivorship is key to understanding and enhancing these survivors' health. …

Effects Of Episodic Food Insecurity On Psychological And Physiological Responses In African American Women With Obesity (Responses): Protocol For A Longitudinal Observational Cohort Study, Candice A. Myers, Robbie A. Beyl, Daniel S. Hsia, Melissa N. Harris, Isabella J. Reed, Danielle D. Eliser, Lauren Bagneris, John W. Apolzan

School of Public Health Faculty Publications

Background; Food insecurity is a risk factor for multiple chronic diseases, including obesity. Importantly, both food insecurity and obesity are more prevalent in African American women than in other groups. Furthermore, food insecurity is considered a cyclic phenomenon, with episodes of food adequacy (ie, enough food to eat) and food shortage (ie, not enough food to eat). More research is needed to better understand why food insecurity is linked to obesity, including acknowledging the episodic nature of food insecurity as a stressor and identifying underlying mechanisms. Objective; The objective of this study is to investigate the episodic nature of food …

Comparison Between The Effects Of Acute Physical And Psychosocial Stress On Feedback-Based Learning, Xiao Yang, Brittany Nackley, Bruce H. Friedman

Psychology Faculty Publications

Stress modulates feedback-based learning, a process that has been implicated in declining mental function in aging and mental disorders. While acute physical and psychosocial stressors have been used interchangeably in studies on feedback-based learning, the two types of stressors involve distinct physiological and psychological processes. Whether the two types of stressors differentially influence feedback processing remains unclear. The present study compared the effects of physical and psychosocial stressors on feedback-based learning. Ninety-six subjects (Mage = 19.11 years; 50 female) completed either a cold pressor task (CPT) or mental arithmetic task (MAT), as the physical or psychosocial stressor, while electrocardiography and …

Role Of Chronic Stress-Induced Neuroinflammation In Rodent Locus Coeruleus Physiology And Anxiety-Like Behaviors, Arthur Anthony Alfonso Reyes

Graduate School of Biomedical Sciences Theses and Dissertations

The locus coeruleus (LC), the primary site of brain norepinephrine (NE), is a key anatomical brain region implicated in the stress response. Stress is a neuroendocrine physiologic response to a stressor that promotes organism survival through adaptive change and restoration of homeostasis. The central stress response, which drives behavioral and physiological change, is primarily mediated by activating the hypothalamic-pituitary-adrenal (HPA) axis. While advantageous in the short term, chronic stress exposure can lead to HPA axis and LC dysregulation, which are thought to contribute to the etiology of anxiety disorders. Previous studies demonstrate the effects of acute stress in increasing LC …

The Benefits Of Art Therapy On Stress And Anxiety Of Oncology Patients During Treatment, Helen Shiepe

Expressive Therapies Capstone Theses

Within the last ten years research on art therapy and its positive impact on oncology patients’ stress and anxiety during treatment has been minimal. Oncology patients whether they are children or adults when diagnosed experience similar reactions due to their diagnosis, treatment, and in some cases end of life care. The current question is whether or not art therapy does have a positive impact on decreasing the stress and anxiety with oncology patients while undergoing treatment. Deane, Fitch & Carmen (2000), discussed art therapy as a healing art that is “intended to integrate physical, emotional, and spiritual care by facilitating …

Social Dominance Alters Stress-Induced Neural Activity And Generates Individual Differences In Stress Vulnerability, Jenna Lee Laymon

Masters Theses

Identifying the physiological and behavioral mechanisms that underlie stress vulnerability is a crucial step toward identifying novel targets for the prevention and treatment of stress-related disorders. Social status is a key environmental factor that contributes to individual variations in stress vulnerability. In particular, achieving a subordinate social status has been shown to produce susceptibility to anxiety-like and depressive-like behavior. In this project, our aim was to identify neural ensembles regulating how dominance status modulated stress-induced changes in avoidant behavior in male and female Syrian hamsters. Using a viral vector that codes for robust activity marker (RAM), we investigated whether stress-induced …

Acupressure Modality Effectiveness: Research Results For Pain And Anxiety, Deanna Waggy Otr, Carroll Noel Mozer Otr/L, Marilyn Zurwaski Otr/L

Journal of Transformative Touch

According to recent studies, including Monson et all, JACM, 2019, there is growing evidence for the effective and safe use of acupressure as a non-pharmacological approach to reducing pain and anxiety. Acupressure can quiet the mind, promoting a sense of well-being by decreasing anxiety.

A collaborative retrospective analysis of self-rated pain and anxiety scores before and immediately after administration of a stress release protocol indicate that acupressure is a highly satisfactory complementary therapy. Results were clinically significant for a decrease in self-rated pain and anxiety scores.

Occupational therapy practitioners as well as those who use the Kawa model of reference …

Conditioned Place Avoidance Is Associated With A Distinct Hippocampal Phenotype, Partly Preserved Pattern Separation, And Reduced Reactive Oxygen Species Production After Stress, D. Parker Kelley, Lucas Albrechet-Souza, Shealan Cruise, Rajani Maiya, Aspasia Destouni, Siva S.V.P. Sakamuri, Alexander Duplooy, Meghan Hibicke, Charles Nichols, Prasad V.G. Katakam, Nicholas W. Gilpin, Joseph Francis

Stress is associated with contextual memory deficits, which may mediate avoidance of trauma-associated contexts in posttraumatic stress disorder. These deficits may emerge from impaired pattern separation, the independent representation of similar experiences by the dentate gyrus-Cornu Ammonis 3 (DG-CA3) circuit of the dorsal hippocampus, which allows for appropriate behavioral responses to specific environmental stimuli. Neurogenesis in the DG is controlled by mitochondrial reactive oxygen species (ROS) production, and may contribute to pattern separation. In Experiment 1, we performed RNA sequencing of the dorsal hippocampus 16 days after stress in rats that either develop conditioned place avoidance to a predator urine-associated …

Chronic Restraint Stress Impairs Voluntary Wheel Running But Has No Effect On Food-Motivated Behavior In Mice, Kiersten Scott, Thien Trong Phan, Nabila Boukelmoune, Cobi J Heijnen, Robert Dantzer

Student and Faculty Publications

Chronic restraint stress is known to cause significant alterations of mitochondrial biology. However, its effects on effort-based behavior and the sensitivity of these effects to treatments that restore mitochondrial function have not been assessed. Based on the hypothesis that the behavioral consequences of this stressor should be more severe for an energy demanding activity than for an energy procuring activity, we compared the effects of chronic restraint stress on the performance of male mice trained to use a running wheel or to nose poke for a food reward in an operant conditioning cage. In accordance with our hypothesis, we observed …

Worried Sick: Understanding The Implications Of Stress On A Physiological Level, Julia Saia

Senior Honors Theses

Stress is prevalent among many individuals in today’s society. A literature review was conducted to investigate the physiological effects of stress, including the biomarkers of stress and how these interact with various body systems. The stress response is a protective mechanism to prepare the body to adequately respond to a perceived threat. However, when this response is prolonged, it begins to have a maladaptive effect on the body and can cause more harm than good. This literature review sought to compile what is known regarding the general effects of chronic stress and its impact on the nervous, immune, digestive, and …

Cue-Induced Cocaine Craving Enhances Psychosocial Stress And Vice Versa In Chronic Cocaine Users, Ann-Kathrin Kexel, Bruno Kluwe-Schiavon, Markus R Baumgartner, Etna J E Engeli, Monika Visentini, Clemens Kirschbaum, Erich Seifritz, Beate Ditzen, Leila M Soravia, Boris B Quednow

Student and Faculty Publications

Stress and craving, it has been found, contribute to the development and maintenance of and relapse in cocaine use disorder. Chronic cocaine users (CU), previous research has shown, display altered physiological responses to psychosocial stress and increased vegetative responding to substance-related cues. However, how psychosocial stress and cue-induced craving interact in relation to the CU's physiological responses remains largely unknown. We thus investigated the interaction between acute psychosocial stress and cocaine-cue-related reactivity in 47 CU and 38 controls. In a crossed and balanced design, the participants were randomly exposed to a video-based cocaine-cue paradigm and the Trier Social Stress Test …

Student and Faculty Publications

Water deficit (WD) combined with high temperature (HT) is the major factor limiting agriculture worldwide, and it is predicted to become worse according to the current climate change scenario. It is thus important to understand how current cultivated crops respond to these stress conditions. Here we investigated how four soybean cultivars respond to WD and HT isolated or in combination at metabolic, physiological, and anatomical levels. The WD + HT increased the level of stress in soybean plants when compared to plants under well-watered (WW), WD, or HT conditions. WD + HT exacerbates the increases in ascorbate peroxidase activity, which …

Student anxiety, specifically test anxiety, is common hindrance to student performance in various courses including Human Anatomy and Physiology at the University of Mississippi. Through a sequence of three surveys we collected demographic information, anxiety data related to the course, and test anxiety in general We researched factors that could potentially influence student anxiety such as at what point in the semester the student is evaluated, when students feel the most stressed, outcomes on previous evaluations, and perceived outcomes of the course. We also examined what effect the anxiety has on the student such as lowered performance, lowered test scores, …

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 Gastrointestinal-Specific Antibiotic As An Experimental Treatment For Anxio-Depressive Disorders, Yuang-Tai Huang

All ETDs from UAB

Chronic stress is a predisposing factor for various disease states, including neuropsychiatric disorders, such as depression and anxiety [1]. Stress-related disorders have complicated multifactorial etiologies [2]. Advances in psychotherapeutic and psychotropic treatments have occurred, but anxiety and depressive disorders are still prevalent and remain a burden to our societies [3]. More than 30% of major depressive disorder patients fail to remission despite an FDAapproved medication [4]. Meanwhile, the contribution of microbiota-gut-brain axis signaling in both etiologies and treatment of stress-related disorders is increasingly being recognized [5]. More evidence has shown that the gut microbiota has the potential to alter the …

Investigating The Influence Of Stress On Motivational Dysfunction In Male And Female Rodents, Emily Laine Errante

Graduate Research Theses & Dissertations

Motivational dysfunction is present in a variety of disorders, including major depressive disorder, schizophrenia, and Parkinsonism and can negatively impact social functioning, employment, and treatment response. Interestingly, outside stressors and stress hormones have been shown to contribute to depressive episodes in humans and depressive-like behaviors in rodents, including reducing motivated behaviors. Effort-related decision making procedures have been utilized in both humans and animals in order to examine motivational dysfunction, as it offers a subject a choice between high effort/reward and low effort/reward options, but little research has examined the effects of stress on effort-related decision making behaviors. Moreover, almost all …

Hormones Can Influence Drug Addiction-A Narrative Review, Morteza Karimian, Hamidreza Famitafreshi

BioMedicine

Drug addiction is a dangerous condition that is the concern of human societies. Nevertheless, several issues exist ahead of people with a drug use disorder during addiction. Accordingly, various types of studies have been conducted to understand better the problems that people with a drug use disorder encountered. People with a drug use disorder usually have a problem tolerating the withdrawal period and some relapse to drug abuse. Complementary studies further revealed that some hormones like oxytocin (OXT), vasopressin, hypothalamic-pituitary-adrenal axis (HPA) axis hormones, sex hormones, thyroid hormones, and nutritional hormones are probably involved in addiction processes. These hormones completely …

The Relationship Of Divine Forgiveness, Victim Forgiveness, And Physical Health Mediated By Stress, Lemuel Josiah C. Ragasajo

Senior Honors Theses

Though there is increasing evidence to support a relationship between forgiveness and physical health, certain subcategories of forgiveness, namely victim and divine forgiveness, are relatively understudied. This study seeks to add to the body of forgiveness literature by examining how divine and victim forgiveness relate to one’s physical health, and whether that relationship is mediated by stress. Furthermore, a literature review is included to detail how stress, a potential mediating variable between forgiveness and physical health, affects physical health. The results of the study reveal that victim forgiveness positively predicts physical health, but is not mediated by stress. In contrast, …

Physician Burnout: Stress Within The Health Care System, Aidan Hauser

English Department: Research for Change - Wicked Problems in Our World

As our nation’s healthcare system expands, more stress and responsibility are placed on our physicians and frontline healthcare workers. The pressures of the daily job often prove extremely damaging to the employee’s mental and physical health. Physician and worker burnout is a growing epidemic that is damaging our care providers more and more every day. Burnout effects not only workers, but all of those surrounding them as well. This plague is not going to be repaired by one single change, but it is clear that many adjustments must be made to reform our healthcare system.

Long-Term Impacts Of Acute Stressor Exposure On Locus Coeruleus Function And Anxiety-Like Behavior In Rats, Olga Borodovitsyna

Graduate School of Biomedical Sciences Theses and Dissertations

Stress is a physiological state characterized by behavioral arousal that occurs during exposure to harmful or threatening stimuli, and usually facilitates an adaptive behavioral response. The persistence of stress sometimes causes it to become maladaptive, potentially contributing to disease development, including physiological complications with altered neuroendocrine signaling and impaired function of organ systems, and psychological conditions including depression and anxiety. Anxiety disorders in particular are associated with a history of stress and are the most common class of mental disorders, with a lifetime prevalence of 33.7% in the general population. The locus coeruleus (LC) is a major node in the …

Glucocorticoid Receptor Antagonist Mifepristone Does Not Alter Innate Anxiety-Like Behavior In Genetically-Selected Marchigian Sardinian (Msp) Rats, Valentina Vozella, Bryan Cruz, Luis A. Natividad, Federica Benvenuti, Nazzareno Cannella, Scott Edwards, Eric P. Zorrilla, Roberto Ciccocioppo, Marisa Roberto

School of Graduate Studies Faculty Publications

Marchigian Sardinian alcohol-preferring (msP) rats serve as a unique model of heightened alcohol preference and anxiety disorders. Their innate enhanced stress and poor stress-coping strategies are driven by a genetic polymorphism of the corticotropin-releasing factor receptor 1 (CRF1) in brain areas involved in glucocorticoid signaling. The activation of glucocorticoid receptors (GRs) regulates the stress response, making GRs a candidate target to treat stress and anxiety. Here, we examined whether mifepristone, a GR antagonist known to reduce alcohol drinking in dependent rats, decreases innate symptoms of anxiety in msPs. Male and female msPs were compared to non-selected Wistar counterparts across three …

Chronic Stress Prevents Cortico-Accumbens Cue Encoding And Alters Conditioned Approach, Mitchell Spring, Aaron Caccamise, Elizabeth A. Panther, Bethany M. Windsor, Karan R. Soni, Jayme R. Mcreynolds, Daniel S. Wheeler, John R. Mantsch, Robert A. Wheeler

Biomedical Sciences Faculty Research and Publications

Chronic stress impairs the function of multiple brain regions and causes severe hedonic and motivational deficits. One brain region known to be susceptible to these effects is the PFC. Neurons in this region, specifically neuronal projections from the prelimbic region (PL) to the nucleus accumbens core (NAcC), have a significant role in promoting motivated approach. However, little is known about how activity in this pathway changes during associative learning to encode cues that promote approach. Less is known about how activity in this pathway may be altered by stress. In this study, an intersectional fiber photometry approach was used in …

Oral Cbd Administration: Assessing Bioavailability And Behavioral Outcomes In A Rodent Model, Jordan Skully

Wayne State University Theses

There has been a recent surge in popularity for cannabidiol (CBD), a major non-psychotropic constituent of cannabis, due to numerous claims of potential therapeutic properties, which include, but are not limited to, anxiolytic, antinociceptive, and anti-inflammatory effects. However, as previous scientific literature on CBD's effectiveness in providing such therapeutic effects is limited, this project was aimed to evaluate the potential beneficial properties of a hemp derived 99% pure CBD compound provided from Ellipse Analytics (Denver, CO) in a rodent model. We analyzed the pharmacokinetics of this CBD product as well as the behavioral outcomes after acute and chronic administration. Pharmacokinetics …

Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez

CMC Senior Theses

Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that changes how people experience the world and affects individuals’ social interactions and often leads to many adverse behaviors. Current literature dictates that a primary contributor to these adverse behaviors is that those with ASD have difficulty determining their own emotional states and determining the physiological signals that their body sends them. A study by Dr. Sarabadani et al. determined that it was possible to monitor the physiology of an individual with ASD and correlate certain signals to emotions, such as stress. These findings indicate the feasibility of establishing a …
