Adolescent oxytocin response to stress and its behavioral and endocrine correlates

Oxytocin (OXT) shows anxiolytic and stress-reducing effects, but salivary OXT response to laboratory-induced stress has only been assessed in one study in healthy adults. The present study aimed at extending these findings by assessing salivary OXT stress reactivity in healthy adolescents (aged 11–18) compared to a control condition. A higher salivary OXT response to stress […]

Effects of parity and litter size on cortisol measures in commercially housed sows and their offspring

Breeding sows are regularly exposed to on-farm stressors throughout the duration of their production period. The impact of such stressors may differ for primi- and multiparous sows, as sows could learn to cope with stressors as they gain experience with them. If parity affects stress in sows, it may also impact their prenatal offspring through […]

Relationship between resilience and stress: Perceived stress, stressful life events, HPA axis response during a stressful task and hair cortisol

Background There is no consensus about how resilience is related to the different types of stress such as daily or chronic stress and psychopathology. The main objective of this study is to evaluate the relationship between resilience and the different measures of stress such as perceived stress, chronic stress, life events, HPA axis response during […]

Zylkéne to load? The effects of alpha-casozepine on compliance and coping in horses during loading

Horses are routinely transported for access to safe off-road riding, veterinary care, breeding, sale, or moving to a new home environment. However, transport is a known stressor in horses. For this reason, problem behavior when loading is a commonly reported issue, which presents risks to handlers and horse welfare. Existing literature and manufacturers’ recommendations suggests […]

Assessing salivary cortisol in large-scale, epidemiological research

Salivary cortisol measures are increasingly being incorporated into large-scale, population-based, or epidemiological research, in which participants are selected to be representative of particular communities or populations of interest, and sample sizes are in the order of hundreds to tens of thousands of participants. These approaches to studying salivary cortisol provide important advantages but pose a […]

Comparison of salivary cortisol concentrations in Jaguars kept in captivity with diff exposures to public

For the most part, jaguars kept in captivity are used for educational and recreational purposes and it hasn’t been determined the different impacts that public exposure would have on these animals. In this study, we compared the salivary cortisol, one of the stress indicator hormones, in seven captive jaguars exposed to the high and low […]

Endocrine response of gilts to various common stressors: A comparison of indicators and methods of analysis

The first aim of the present study was to determine whether various common events encountered by pigs in commercial farms or experimental units induce activation of the sympathetic and hypothalamo-pituitary-adrenal (HPA) axes. The second aim was to compare the efficiency of various indicators and methods of analysis to detect the occurrence of a stress reaction. […]

Influence of acute stress on spatial tasks in humans

Few studies have investigated the relationship between stress and spatial performance in humans. In this study, participants were exposed to an acute laboratory stressor (Star Mirror Tracing Task) or a control condition (watching a nature video) and then performed two spatial tasks. In the first task, participants navigated through a virtual reality (VR) environment and […]

Human interaction and cortisol: Can human contact reduce stress for shelter dogs?

Animal shelters are an extremely stressful environment for a dog, most specifically due to social isolation and novel surroundings. The stress response of dogs housed in this environment may be alleviated through human interaction shortly after arrival. During their second day in a public animal shelter, adult stray dogs were either engaged in a human […]

Validation of a cortisol enzyme immunoassay and characterization of salivary cortisol circadian rhythm in chimpanzees (Pan troglodytes)

Abstract Monitoring concentrations of stress hormones is an important tool for behavioral research and conservation for animals both in the wild and captivity. Glucocorticoids can be measured in mammals as an indicator of stress by analyzing blood, feces, urine, hair, feathers, or saliva. The advantages of using saliva for measuring cortisol concentrations are three-fold: it […]
