Rapid-Onset Anti-Stress Effects Of A Kappa-Opioid Receptor Antagonist, Ly2795050, Against Immobility In An Open Space Swim Paradigm In Male And Female Mice, Caroline Baynard, Thomas E. Prisinzano, Eduardo R. Butelman

Pharmaceutical Sciences Faculty Publications

The kappa-opioid receptor (KOR) / dynorphin system is implicated with behavioral and neurobiological effects of stress exposure (including heavy exposure to drugs of abuse) in translational animal models. Thus some KOR-antagonists can decrease the aversive, depressant-like and anxiety-like effects caused by stress exposure. The first generation of selective KOR-antagonists have slow onsets (hours) and extremely long durations of action (days-weeks), in vivo. A new generation of KOR antagonists with rapid onset and shorter duration of action can potentially decrease the effects of stress exposure in translational models, and may be of interest for medication development. This study examined the …

The Effect Of Multimethodological Emotional Intelligence Training On Emotional Intelligence Levels In Nurses At An Academic Medical Center, Chad Eldridge Jan 2021

The Effect Of Multimethodological Emotional Intelligence Training On Emotional Intelligence Levels In Nurses At An Academic Medical Center, Chad Eldridge

DNP Projects

Background: Stress levels associated with the nursing career can be amplified by hostile social environments in the workplace, horizontal aggression, lack of leadership support, and poor communication. This can lead to poor retention rates and increased burnout.

Conversely, supportive work environments positively influence nursing sensitive quality indicators such as patient satisfaction, nosocomial infections, patient falls, pressure ulcers, and medication errors. Strong relationships enhance workplace social capital leading to an increased sense of belonging, strengthened mental health, and improved job satisfaction ratings.

Executive nurse leaders can promote an empowering environment dedicated to the physical, mental, and social well-being of their staff …

Bandura’s theory focuses on the belief that individuals can influence their own lives.

Methodology: This study employed a descriptive, pretest-posttest single site comparative design. Sixty-six nursing leaders from …


Associations Between Psychosocial Stressors, Genes, And Cardiovascular Disease In At-Risk Adults, Kaitlin Voigts Key Jan 2020

Associations Between Psychosocial Stressors, Genes, And Cardiovascular Disease In At-Risk Adults, Kaitlin Voigts Key

Theses and Dissertations--Nursing

Psychosocial stressors have a significant adverse impact on cardiovascular health. While better medical treatments and increased emphasis on healthy lifestyle have improved cardiovascular health for many in the United States over the past 50 years, there are persistent inequities in cardiovascular disease (CVD) rates, with the highest rates among populations burdened by chronic exposure to psychosocial stressors such as discrimination and anxiety, among others. Genetic factors may interact with these stressors further influencing the rates of CVD in these populations. The purpose of this dissertation is to examine associations among psychosocial stressors and other CVD risk factors, and the influence …

Chronic stress triggers activation of the sympathetic nervous system and drives malignancy. Using an immunodeficient murine system, we showed that chronic stress–induced epinephrine promoted breast cancer stem-like properties via lactate dehydrogenase A–dependent (LDHA-dependent) metabolic rewiring. Chronic stress–induced epinephrine activated LDHA to generate lactate, and the adjusted pH directed USP28-mediated deubiquitination and stabilization of MYC. The SLUG promoter was then activated by MYC, which promoted development of breast cancer stem-like traits. Using a drug screen that targeted LDHA, we found that a chronic stress–induced cancer stem-like phenotype could be reversed by vitamin C. These findings demonstrated the critical importance of psychological …


Race-Based Discrimination, Occupational Stress, And Depression In Black Registered Nurses, Arica A. Brandford Jan 2019

Race-Based Discrimination, Occupational Stress, And Depression In Black Registered Nurses, Arica A. Brandford

Theses and Dissertations--Nursing

The purpose of this dissertation was to examine depression, experiences of work-related racism, and occupational stress among black nurses. Nursing is a highly stressful and demanding profession that can negatively affect health. Underscoring this is the high rate of depression experienced by nurses. In fact, nurses experience depression at a rate twice that of individuals in other occupations. Examining depression in nurses can provide insights that can inform measures addressing the psychological health of this group. This may be particularly important in black nurses who, in addition to the already high occupational stress associated with nursing, may experience additional stress …


The Role Of Stress In The Pathogenesis And Maintenance Of Obsessive-Compulsive Disorder, Thomas G. Adams, Benjamin Kelmendi, C. Alex Brake, Patricia Gruner, Christal L. Badour, Christopher Pittenger Mar 2018

The Role Of Stress In The Pathogenesis And Maintenance Of Obsessive-Compulsive Disorder, Thomas G. Adams, Benjamin Kelmendi, C. Alex Brake, Patricia Gruner, Christal L. Badour, Christopher Pittenger

Psychology Faculty Publications

Individuals with obsessive-compulsive disorder often identify psychosocial stress as a factor that exacerbates their symptoms, and many trace the onset of symptoms to a stressful period of life or a discrete traumatic incident. However, the pathophysiological relationship between stress and obsessive-compulsive disorder remains poorly characterized: it is unclear whether trauma or stress is an independent cause of obsessive-compulsive disorder symptoms, a triggering factor that interacts with a preexisting diathesis, or simply a nonspecific factor that can exacerbate obsessive-compulsive disorder along with other aspects of psychiatric symptomatology. Nonetheless, preclinical research has demonstrated that stress has conspicuous effects on corticostriatal and limbic …


Acute Pressor Response To Psychosocial Stress Is Dependent On Endothelium‐Derived Endothelin‐1, Brandon M. Fox, Bryan K. Becker, Analia S. Loria, Kelly A. Hyndman, Chunhua Jin, Hannah Clark, Robin Johns, Masashi Yanagisawa, David M. Pollock, Jennifer S. Pollock Feb 2018

Acute Pressor Response To Psychosocial Stress Is Dependent On Endothelium‐Derived Endothelin‐1, Brandon M. Fox, Bryan K. Becker, Analia S. Loria, Kelly A. Hyndman, Chunhua Jin, Hannah Clark, Robin Johns, Masashi Yanagisawa, David M. Pollock, Jennifer S. Pollock

Pharmacology and Nutritional Sciences Faculty Publications

Background

Acute psychosocial stress provokes increases in circulating endothelin‐1 (ET‐1) levels in humans and animal models. However, key questions about the physiological function and cellular source of stress‐induced ET‐1 remain unanswered. We hypothesized that endothelium‐derived ET‐1 contributes to the acute pressor response to stress via activation of the endothelin A receptor.

Methods and Results

Adult male vascular endothelium‐specific ET‐1 knockout mice and control mice that were homozygous for the floxed allele were exposed to acute psychosocial stress in the form of cage switch stress (CSS), with blood pressure measured by telemetry. An acute pressor response was elicited by CSS in …


Tissues And Trauma: Pain Neuroscience Education For Veterans With Post-Traumatic Stress And Low Back Pain, Timothy Mark Benedict Jan 2018

Tissues And Trauma: Pain Neuroscience Education For Veterans With Post-Traumatic Stress And Low Back Pain, Timothy Mark Benedict

Theses and Dissertations--Rehabilitation Sciences

Low back pain (LBP) is the top reason for Soldiers to seek medical care and one of the top reasons to be medically discharged. Mental health problems and psychosocial stressors have been increasing in Soldiers and are also top causes for medical discharge. Dysregulated stress has contributed to many Soldiers and Veterans to develop chronic LBP as well as mental health disorders like post-traumatic stress disorder (PTSD). Research suggests that psychosocial characteristics, as opposed to physical factors or tissue health, contribute to chronic pain the most. Focusing entirely on tissues for individuals seeking care for LBP can increase disability and …

Physiology Faculty Publications

Stress and glucocorticoid (GC) release are common behavioral and hormonal responses to injury or disease. In the brain, stress/GCs can alter neuron structure and function leading to cognitive impairment. Stress and GCs also exacerbate pain, but whether a corresponding change occurs in structural plasticity of sensory neurons is unknown. Here, we show that in female mice (Mus musculus) basal GC receptor (Nr3c1, also known as GR) expression in dorsal root ganglion (DRG) sensory neurons is 15-fold higher than in neurons in canonical stress-responsive brain regions (M. musculus). In response to stress or GCs, adult …

Perceived Stress, Caffeine Consumption, And Gpa Of Undergraduate Students At A Large Public University, Emma Simpson Jan 2016

Perceived Stress, Caffeine Consumption, And Gpa Of Undergraduate Students At A Large Public University, Emma Simpson

Theses and Dissertations--Nutrition and Food Systems

Evidence suggests that college students may increase caffeine consumption to cope with the stress and demands of college. The relationships between perceived stress, caffeine consumption, and GPA were examined in students at a large public university. Students were surveyed to determine perceived stress (Cohen’s Perceived Stress Questionnaire), beliefs about caffeine, caffeine consumption, workload in and outside of the classroom, and GPA. Surveys were administered at the beginning of the semester and again at midterm. Based on Cohen’s 40-point scale, average stress scores increased from 15.95 ± 6.34 at the beginning of the semester to 18.89 ± 6.94 at midterms. Additionally, …


Co-Morbid Symptoms Of Depression And Anxiety And Bio-Behavioral Response To Stress In Patients With Heart Failure, Abdullah S. Alhurani Jan 2016

Co-Morbid Symptoms Of Depression And Anxiety And Bio-Behavioral Response To Stress In Patients With Heart Failure, Abdullah S. Alhurani

Theses and Dissertations--Nursing

Heart failure (HF) is a major public health problem throughout the world. It accounts for one death certificate among nine in the United States. Heart failure and sudden death combined are responsible for the largest number of deaths in America. The total costs of HF in the United States are estimated to be $37 billion each year. Despite substantial medical and surgical advances related to treatment of HF, it remains a very costly condition with high mortality and morbidity rates. Although biological factors contribute to high morbidity and mortality in HF, there are many unexplored psychosocial factors that also likely …

Mattingly, Sage P. Kramer, Cassi M. Binkley, Linyuan Jing, Jonathan D. Suever, David K. Powell, Richard J. Charnigo, Frederick H. Epstein, Brandon K. Fornwalt

Saha Cardiovascular Research Center Faculty Publications

BACKGROUND: Obesity is a risk factor for cardiovascular disease. There is evidence of impaired left ventricular (LV) function associated with obesity, which may relate to cardiovascular mortality, but some studies have reported no dysfunction. Ventricular function data are generally acquired under resting conditions, which could mask subtle differences and potentially contribute to these contradictory findings. Furthermore, abnormal ventricular mechanics (strains, strain rates, and torsion) may manifest prior to global changes in cardiac function (i.e., ejection fraction) and may therefore represent more sensitive markers of cardiovascular disease. This study evaluated LV mechanics under both resting and stress conditions with the hypothesis …


Drug Synergy Drives Conserved Pathways To Increase Fission Yeast Lifespan, Xinhe Huang, Markos Leggas, Robert C. Dickson Mar 2015

Drug Synergy Drives Conserved Pathways To Increase Fission Yeast Lifespan, Xinhe Huang, Markos Leggas, Robert C. Dickson

Pharmaceutical Sciences Faculty Publications

Aging occurs over time with gradual and progressive loss of physiological function. Strategies to reduce the rate of functional loss and mitigate the subsequent onset of deadly age-related diseases are being sought. We demonstrated previously that a combination of rapamycin and myriocin reduces age-related functional loss in the Baker's yeast Saccharomyces cerevisiae and produces a synergistic increase in lifespan. Here we show that the same drug combination also produces a synergistic increase in the lifespan of the fission yeast Schizosaccharomyces pombe and does so by controlling signal transduction pathways conserved across a wide evolutionary time span ranging from yeasts to …


Factors Facilitating Constructive Coping With Stress, Kamilla Bargiel-Matusiewicz, Hatim A. Omar Jan 2015

Factors Facilitating Constructive Coping With Stress, Kamilla Bargiel-Matusiewicz, Hatim A. Omar

Pediatrics Faculty Publications

This review focuses on coping with stress, with particular emphasis on mechanisms facilitating constructive coping with stress. An important area of contemporary research is the attempt to identify factors that make it possible to stay mentally healthy or preventing the weakening of the cognitive and social functioning. The currently prevailing approach to stress is the relational approach. According to this approach, the criterion for the occurrence of stress is the cognitive assessment of the situation made by an individual. This review presents the most recent proposals concerning the analysis of specific methods of coping with stress, in particular from the …

Stress In Parents Of Children With Type 1 Diabetes, Megan B. Carter Jan 2015

Stress In Parents Of Children With Type 1 Diabetes, Megan B. Carter

DNP Projects

Pediatric healthcare providers across the country care for many children with complex chronic diseases. Many of these children are not developmentally mature enough to manage their disease process, leaving the parent of the chronically ill child to manage their disease. The parent of the chronically ill child may experience stress related to their child’s illness, termed pediatric parenting stress, and may have difficulty dealing with this stress (Streisand, Kazak, & Tercyak, 2003). The manuscripts in this Practice Inquiry Project further investigate the relationship between pediatric parenting stress and the health of the parent and the chronically ill child. The instruments …

Saha Cardiovascular Research Center Faculty Publications

BACKGROUND: Cardiovascular magnetic resonance using displacement encoding with stimulated echoes (DENSE) is capable of assessing advanced measures of cardiac mechanics such as strain and torsion. A potential hurdle to widespread clinical adoption of DENSE is the time required to manually segment the myocardium during post-processing of the images. To overcome this hurdle, we proposed a radical approach in which only three contours per image slice are required for post-processing (instead of the typical 30-40 contours per image slice). We hypothesized that peak left ventricular circumferential, longitudinal and radial strains and torsion could be accurately quantified using this simplified analysis.

METHODS …

Toxicology and Cancer Biology Faculty Publications

Leukemia is a leading cause of cancer death. Recently, the latexin (Lxn) gene was identified as a potential tumor suppressor in several types of solid tumors and lymphoma, and Lxn expression was found to be absent or downregulated in leukemic cells. Whether Lxn functions as a tumor suppressor in leukemia and what molecular and cellular mechanisms are involved are unknown. In this study, the myeloid leukemogenic FDC-P1 cell line was used as a model system and Lxn was ectopically expressed in these cells. Using the protein pull-down assay and mass spectrometry, ribosomal protein subunit 3 (Rps3) was identified as a …

Kramer, David K. Powell, Christopher M. Haggerty, Cassi M. Binkley, Andrea C. Mattingly, Lisa A. Cassis, Frederick H. Epstein, Brandon K. Fornwalt

Pediatrics Faculty Publications

BACKGROUND: Obesity affects a third of adults in the US and results in an increased risk of cardiovascular mortality. While the mechanisms underlying this increased risk are not well understood, animal models of obesity have shown direct effects on the heart such as steatosis and fibrosis, which may affect cardiac function. However, the effect of obesity on cardiac function in animal models is not well-defined. We hypothesized that diet-induced obesity in mice reduces strain, torsion, and synchrony in the left ventricle (LV).

METHODS: Ten 12-week-old C57BL/6 J mice were randomized to a high-fat or low-fat diet. After 5 months on …

Markey Cancer Center Faculty Publications

The issue of how contractility and adhesion are related to cell shape and migration pattern remains largely unresolved. In this paper we report that Gleevec (Imatinib), an Abl family kinase inhibitor, produces a profound change in the shape and migration of rat bladder tumor cells (NBTII) plated on collagen-coated substrates. Cells treated with Gleevec adopt a highly spread D-shape and migrate more rapidly with greater persistence. Accompanying this more spread state is an increase in integrin-mediated adhesion coupled with increases in the size and number of discrete adhesions. In addition, both total internal reflection fluorescence microscopy (TIRFM) and interference reflection …
