Neurochemical Effects Of Amyloid-Beta Oligomers In Rats, John J. Panos

Dissertations

Alzheimer’s disease is a progressive neurodegenerative disease characterized by memory loss and cognitive decline. Although the symptomology of Alzheimer’s disease is well defined, its precise etiology remains elusive. Animal models are invaluable for understanding the pathogenesis of this devastating disease. Knowledge of the neurochemical actions of amyloid-β oligomers in specific brain structures is essential for validating animal models of Alzheimer’s disease and for determining the most appropriate behavioral assays of memory. The specific aim of this project was to investigate the neurochemical effects of direct intracerebral infusion of amyloid-β oligomers in the rat. Experiment 1 investigated direct infusions of synthetic …

Loma Linda University Electronic Theses, Dissertations & Projects

Background

Obesity is a major concern in the United States and Black Americans are among those with the highest rates of overweight, obesity, and related co- morbidities.

Purpose

The purpose of this study was to analyze the relationships among spirituality, self-efficacy for physical activity and healthy eating, and body composition measures among Black women over the period of participation …

Effect Of Depression On Attention Via Mood Induction In A Healthy Population, Cheryl Mae Calvano

Loma Linda University Electronic Theses, Dissertations & Projects

This project continues research into the cognitive attention of persons with a sad mood similar to that experienced by dysthymia. The project utilizes the Dot Probe Task to evaluate attention to affective stimuli presented in the International Affective Picture Set (IAPS). Participants were psychology students recruited from La Sierra University. Participants completed a word task that intended to induce a sad or neutral mood. The Positive and Negative Affect Scale (PANAS) was used to evaluate the efficacy of the mood induction. Overall, participant’s negative PANAS scale did not differ between groups. Groups differed between administrations of the PANAS on the …

Psychometric Properties Of The Psychopathic Personality Inventory In A Non-Criminal Population, Julie Madeleine Woltil

Loma Linda University Electronic Theses, Dissertations & Projects

The Psychopathic Personality Inventory (PPI) is a self-report measure which was created to identify the personality traits of psychopathy in noncriminal populations. These personality traits were grouped into eight subscales in the PPI including Machiavellian Egocentricity, Social Potency, Coldheartedness, Carefree Nonplanfulness, Fearlessness, Blame Externalization, Impulsive Nonconformity and Stress Immunity. The hypothesized relationships and factor structure of this study follow the theory of psychopathy as being a disorder rooted in antisocial behaviors (often aggressive and impulsive in nature) and inappropriate emotional reactivity (characterized as a lack in empathy and anxiety). A confirmatory factor analysis was done with an ethnically diverse undergraduate …

Effects Of Patient Trauma On Hospital Staff Functioning: An Exploratory Study Of Psychological Distress Resulting From Trauma Exposure, Randy Allen Braley

Electronic Theses and Dissertations

The present study attempted to determine the relationship between exposure to traumatic experiences of hospitalized children and adolescents and the development of secondary traumatic stress, also known as compassion fatigue, vicarious traumatization, or burnout in clinical staff working with such patients. Hierarchical regression was used to test the hypotheses that: clinical treatment staff will experience higher levels of psychological distress following exposure to patient trauma and previous lifetime trauma events; clinical treatment staff will experience quality of patient relationships associated with the degree of exposure to patient trauma, previous lifetime or work-related trauma history, and level of supervisor support; clinical …
