Effects of gender-affirming hormones on diurnal cortisol concentrations: A prospective study

Neurobiology of Stress
The diurnal rhythm of the hypothalamic-pituitary-adrenal (HPA) axis is essential for physical and mental health. There are sex differences in this diurnal rhythm, including steeper diurnal cortisol slopes in females compared to males, and sex hormones ...

Salivary Cortisol Reaction Norms in Zoo-Housed Great Apes: Diurnal Slopes and Intercepts as Indicators of Stress Response Quality

Animals, 2022
Monitoring changes in cortisol levels is a widespread tool for measuring individuals’ stress responses. However, an acute increase in cortisol levels does not necessarily denote an individual in distress, as increases in cortisol can be elicited by all ...

PK/PD modeling of 5‐hydroxytryptophan (5‐HTP) challenge test with cortisol measurement in serum and saliva

Pharmacology Research & Perspectives, 2020
This research was planned to build a Pharmacokinetic/Pharmacodynamic (PK/PD) model of 5‐hydroxytryptophan (5‐HTP) challenge study including a circadian rhythm component of cortisol and to predict serum cortisol based on saliva cortisol. Data from three 5‐

Scales tell a story on the stress history of fish. [PDF]

PLoS ONE, 2015
Fish faced with stressful stimuli launch an endocrine stress response through activation of the hypothalamic-pituitary-interrenal (HPI-) axis to release cortisol into the blood.

Yawning, fatigue, and cortisol: Expanding the Thompson Cortisol Hypothesis

Medical Hypotheses, 2014
Yawning and its involvement in neurological disorders has become the new scientific conundrum. Cortisol levels are known to rise during stress and fatigue; yawning may occur when we are under stress or tired. However, the link between yawning, fatigue, and cortisol has not been fully understood.

Sex differences in the association between internalizing symptoms and hair cortisol level among 10-12 year-old adolescents in China. [PDF]

PLoS ONE, 2018
Although numerous studies have described the relationship between HPA axis dysregulation and internalizing symptoms among adolescents, research using hair cortisol concentrations in pre- and young adolescent samples has not been reported. We investigated

Reevaluating the use of metanephrine in adrenal vein sampling: a single centre retrospective study

Endocrine Connections
Optimal treatment of primary aldosteronism (PA) requires precise subtyping, usually performed by adrenal vein sampling (AVS) using cortisol to assess selectivity.

Cortisol

Les hormones corticoesteroides són essencials per a la regulació d'una gran varietat de processos fisiològics. El cortisol és el principal corticoesteroide en peixos teleostis, amb funcions glucocorticoides i mineralocorticoides. És el principal indicador de la resposta a l'estrès, i la principal hormona en el control de l'osmorregulació en peixos ...

Gut Bacteria Improve Depressive Symptoms by Degrading Cortisol into Androgen

Advanced Science
Gut microbiota may play a role in regulating the stress hormone cortisol. However, the mechanisms underlying the regulation of cortisol by gut microbiota are poorly understood.

The Value of Adrenal Androgens for Correcting Cortisol Lateralization in Adrenal Venous Sampling in Patients with Normal Cortisol Secretion

International Journal of Endocrinology, 2019
The management of patients with adrenocorticotropic hormone-independent Cushing’s syndrome and bilateral adrenal masses is challenging. Adrenal venous sampling (AVS) has been used to identify functional lesions in previous studies, but it is not always ...
