Detection and measurement of stress hormones with mass spectrometry
… rate. Saliva samples were collected at rest, and hormones measured with the new LC-MS method and ELISA to validate the developed method. Finally, heart rate and salivary and plasma cortisol and testosterone response to acute exercise were tested, to compare the response to different training …

Interaction between cell adhesion molecules and stress hormones following different intensities of cycling exercise in obese males.
… examine the interaction between exercise-induced stress hormones [epinephrine (E), norepinephrine (NE), and cortisol (COR)] and soluble cell adhesion molecules [soluble intercellular adhesion molecule 1(sICAM-1), soluble vascular cell adhesion molecule 1(sVCAM-1), and soluble endothelial selectin …

The relationship between boron, stress hormones and bone markers in humans of different ages, life style and health status
Hormones (sex hormones, thyroxine, cortisol and parathyroid), cytokines (interleukins-1 and 2 and tumour necrosis factor), life style (exercise, smoking and reproductive history), nutrition (calcium, meat, vegetables, vitamin D, caffeine and alcohol) and diseases (diabetes mellitus, malabsorption …

Non-invasive assessment of stress hormones, parasites, and diet, using scat of five felid species in Belize, Central America
… consequences of this conflict are an increase in stress impacting health, diet shifts, or heightening of animal aggression. The goal of this work was to assess the effects of human-modified habitats on native felids by comparing fecal glucocorticoid metabolite (FGM) concentrations, endoparasite …

The effects of stress hormones on preferences for acoustic signals in female green treefrogs (Hyla cinerea) and barking treefrogs (Hyla gratiosa)
Ecological stressors (i.e., high predator density, low food availability) are often associated with increased variation in mate choice by females. The association between environmental stressors and variation in mate choice suggests that circulating stress hormones (i.e., glucocorticoids) may …

Stress hormones epinephrine and corticosterone modulate herpes simplex virus 1 and 2 productive infection and reactivation primarily in sympathetic, not sensory, neurons
… disease throughout the life of the host. Stress is associated with exacerbation of clinical symptoms and induction of recurrences in humans and animal models. The viruses preferentially replicate and establish latency in different subtypes of sensory neurons, as well as in neurons of the …

Are Highways Stressful for Pikas?: Analysis of Stress Hormones of the American Pika (<i>Ochotona princeps</i>) Living Adjacent to Interstate 90 in the Cascade Range of Washington State
… but their fitness in these potentially stressful environments is poorly understood. Chronic stress alters behavior, reduces reproduction, and has been linked to reduced survival. Animals affected by chronic stress in road-adjacent habitats could reduce the ability of wildlife crossing …

Differential regulation of herpes simplex virus-1 and herpes simplex virus-2 during latency and post reactivation in response to stress hormones and nerve trauma in primary adult sensory and sympathetic neurons
… innervate the site of infection. Any cellular stress trigger, ranging from external stimuli such as UV radiation or nerve injury to psychological and physiological stress, can reactivate HSV from latency in the neurons, resulting in recurrent disease episodes. Stress hormones and deprivation of …

Effect of Sympathetic Nervous System Mediators On The Tumor Microenvironment Via Small Extracellular Vesicles In Ovarian Cancer
… Anil K. Sood, MD</p> <p>Background:Psychological stress can promote progression of gynecological malignancies by increasing secretion of sympathetic nervous system (SNS) mediators, namely catecholamines. However, the mechanisms underlying these effects are poorly explored. Here, we examined the …

Extended Adolescence: The Ecology and Endocrinology of Facultative Paedomorphosis
… density, predator presence, hydroperiod, and stress hormones in regulating the expression of paedomorphosis. Results indicated the regulation of paedomorphosis through multiple ecological factors may be reducible to density-mediated effects, with a few notable exceptions. I also show that …

Association of Maternal Cumulative Risk during Pregnancy and IQ in Preschoolers: Role of Glucocorticoids and their Receptors
… which lead to chronic, elevated levels of stress. Constant elevations of maternal stress hormones during pregnancy disrupt developing fetal brain chemistry and architecture, resulting in later memory and learning deficiencies. While we know that the quality of the fetal environment and the …

Daily stressors and memory failures in a naturalistic setting: Findings from the normative aging study
The role of stress in memory functioning has typically been examined in the laboratory with biological indicators of stress (i.e., stress hormones) and cognitive tests. These studies have generally found a negative association between stress and cognitive performance; that is, people who have …

The effect of night time diuretic chronotherapy on quality and duration of sleep among Zambian hypertensive patients
… rate to 60%. It is thought that sleep regulates stress hormones and helps nervous system. Overtime, lack of sleep hurt the body ability to regulate stress hormones, leading to high blood pressure. The night time dosing of blood pressure lowering drugs have yielded positive results. Scholars have …

Neuropharmacological Mechanisms Underlying Incentive Salience and Stress
… Given the frequent presentation of anhedonia in stress-related psychiatric disorders, we hypothesized that exposure to stressors disrupts brain signaling pathways that would typically facilitate reward processing. The experiments in this thesis utilized the novelty-induced hypophagia (NIH) test, …
