Psychological Hardiness and Biochemical Markers of Acute Stress
… before and after a mid-term examination stressor. Normative data was collected on the reported frequency of stressors and their severity one week prior to the examination, and self-reported ratings of stress immediately prior to the examination. Performance on the examination as a …

Salivary VIP concentrations are elevated in humans after acute stress
… two salivary neuropeptides in the context of the stress response. The research was focused first and foremost on evaluating the usefulness of salivary Neuropeptide Y (NPY) and salivary vasoactive intestinal peptide (VIP) as stress indicators. Secondly, we questioned whether these markers help us …

Salivary Biomarkers of Acute Stress and Insulin Sensitivity in Nonhuman Primates
… alpha-amylase (sAA) is a novel biomarker of stress in humans, has implications with diabetes, and could be a new tool for improving health and welfare in zoo animals. The goals of our study were to 1) validate measures of salivary insulin, cortisol and sAA and 2) explore relationships between …

The effects of acute stress on retrieval of visual and spatial material
… human and non-human animal samples, suggest that stress impairs memory retrieval. However, most human studies that report these impairing effects explore verbal memory only. The aim of the studies reported in this dissertation was to explore the effects of an acute stressor (Study 1), and of …

Evaluation of biofeedback components for the management of acute stress in healthcare
… is understanding and mitigating the impact of acute stress experienced by surgeons. Previous research demonstrates the detrimental effects mismanaged acute stress can have on cognitive performance integral in optimal surgical practice. Biofeedback consists of objectively monitoring signs of …

Subjective and Physiological Responses to Acute Stress in Socially Anxious Adults and Healthy Children
… the subjective and physiological responses to an acute stress in the context of treatment and risk factors for SAD. The goal of the first study was to examine whether cognitive behavioural group therapy (CBGT) and a mindfulness-based stress reduction (MBSR) program differentially influenced the …

Establishing dose-response curves for the impact of urban forests on recovery from acute stress and landscape preference
… that exposure to urban forests can help reduce stress in individuals, the shape of the dose-response curve is entirely unclear. It is not known if a small amount of nature is enough to induce stress recovery effects, whether increases in the tree cover density produce additional stress recovery …

ACUTE STRESS, BUT NOT CORTICOSTERONE, FACILITATES ACQUISITION OF PAIRED ASSOCIATES LEARNING ASSESSED IN RATS USING TOUCHSCREEN-EQUIPPED OPERANT CONDITIONING CHAMBERS
Acute stress is well known to influence learning and memory tasks in humans and rodents, enhancing performance in some instances while impairing it in others. Across species, subjects preferentially employ striatal mediated stimulus-response strategies in spatial memory tasks following stress, …

The Course of Acute Stress Disorder and Post Traumatic Stress Disorder In Parents With Infants In The Neonatal Intensive Care Unit
… parents have up to a 60% chance to develop acute stress disorder (ASD) and/or post-traumatic stress disorder (PTSD) during or after their baby’s NICU stay. Emotional and demographic factors contributing to ASD/PTSD have been previously identified. Although support factors desired by NICU …

INVESTIGATION OF ACUTE STRESS IMPACT ON NURSERY PIG GASTROINTESTINAL FUNCTION AND ABILITY OF BIOACTIVE COMPONENTS OF GARLIC TO MITIGATE STRESS-INDUCED PHYSIOLOGICAL CHANGES
… event resulted in an increase in serum stress markers and altered intestinal morphology and tight junction gene expression during the first week post-weaning. Furthermore, the acute post-weaning deprivation event impacted growth performance throughout the nursery period and resulted in …

Modeling “Abnormal” Ovulatory Dynamics: Enzymes, Insulin, and the Impact of Stress
<p>This work focuses on modeling the impact of stress on ovulatory dynamics. We develop a mathematical model of endocrine processes including gonadotropin-releasing hormone, kisspeptin signaling, and the ovulatory cycle. Integral to our model development, we define ovulatory criteria, conduct an …

Exploring whether household pets buffer responses to a remote stress induction
Within the field of research examining stress reactivity, there have been recent strides to modify the Trier Social Stress Test (TSST) to be administered remotely, with user-friendly and accessible means of collecting physiological measures of an acute stress response. Research regarding stress …

Maternal High-Salt Diet During Pregnancy in Sprague Dawley Rats Programs Exaggerated Stress-Induced Blood Pressure and Heart Rate Responses in Adult Female Offspring
… in restraining cages to test for a programmed acute stress hyperresponsiveness. Offspring were challenged with HS diet for one week to determine if blood pressure salt sensitivity had been programmed by the prenatal HS diet. Animals were killed following resting and acute stress conditions, …

The influence of cognitive biases on psychophysiological vulnerability to stress
… bias) report more psychological ill-effects of stress than those with balanced or positively-skewed inclinations. Cognitive Bias Modification (CBM) techniques improve maladaptive biases through implicitly-based association learning, with induced positive biases buffering the future perception of …

An investigation into the use of infrared thermography as a tool to assess the physiological stress response in the horse
… method to identify the physiological stress response in the horse. The primary area of investigation was the eye area within the medial posterior palpebral border of the lower eyelid and the lacrimal caruncle as in existing work in other species. The application of these findings to …

Stress-induced Alterations in Mast Cell Numbers and Proteinase-activated Receptor-2 Expression of the Colon:Role of Corticotrophin-releasing factor
… study was performed in order to assess whether acute stress can increase mast cell and enterochromaffin (EC) cell numbers, and proteinase-activated receptor-2 (PAR2) expression in the rat colon. In addition, we aimed to investigate the involvement of corticotrophin-releasing factor in these …
