Salivary cortisol as a biomarker in stress research.
TLDR
The present paper addresses several psychological and biological variables, which may account for such dissociations, and aims to help researchers to rate the validity and psychobiological significance of salivary cortisol as an HPAA biomarker of stress in their experiments.About:

Stress During Pregnancy Experienced Stress, Stress Hormones, and Protective Factors
TL;DR: This paper reviewed the literature on experienced stress and stress hormones in pregnant women and presented studies that used standardized stress challenges (e.g., the Trier Social Stress Test, the cort...

Nature, correlates, and consequences of stress-related biological reactivity and regulation in Army nurses during combat casualty simulation
Leigh McGraw,Dorothée Out,Dorothée Out,Jon Hammermeister,Carl Ohlson,Michael A. Pickering,Douglas A. Granger +6 more
TL;DR: Results revealed large magnitude increases in cortisol, sAA, HR, systolic BP and diastolic BP in response to the Combat Casualty Stress Scenario, followed by recovery to baseline levels 30min after the task for all physiological parameters except cortisol.
Journal ArticleDOI
Influence of mental stress on the pulse wave features of photoplethysmograms.
TL;DR: In-vivo results showed that the two first parameters responded significantly to increased mental stress and to a breathing relaxation procedure, complementing heart rate, heart rate variability, and pulse transit time as indices of stress.

Using personality ratings and cortisol to characterize individual differences in African Elephants (Loxodonta africana)
Alison P. Grand,Christopher W. Kuhar,Katherine A. Leighty,Tamara L. Bettinger,Mark L. Laudenslager +4 more
TL;DR: In this paper, a combined behavioral and physiological approach has been examined in captive African elephants (Loxodonta africana) using serum and salivary cortisol measurements and their Elephant Behavior Index, a personality rating system modified from an index designed for nonhuman primates.

Sputum interleukin-6, tumor necrosis factor-α and Salivary cortisol as new biomarkers of depression in lung cancer patients
Yijie Du,Hongying Zhang,Bei Li,Xiao Wu,Yubao Lv,Hualiang Jin,Yuxue Cao,Jing Sun,Qingli Luo,Weiyi Gong,Baojun Liu,Jinfeng Wu,Shen-xun Shi,Jingcheng Dong +13 more
TL;DR: It is suggested that higher 24h overall levels of sputum IL-6, TNF-α and flattened diurnal salivary cortisol slopes were associated with depression in lung cancer patients.

Impact of gender, menstrual cycle phase, and oral contraceptives on the activity of the hypothalamus-pituitary-adrenal axis.
TL;DR: Although men seem to have a stronger hypothalamic drive in response to stressful stimulation than women, differences in salivary-free cortisol levels, at least in part, may be explained by estradiol-induced changes in corticosteroid-binding protein levels.

Free Cortisol Levels after Awakening: A Reliable Biological Marker for the Assessment of Adrenocortical Activity
Jens C. Pruessner,Oliver T. Wolf,Dirk H. Hellhammer,Angelika Buske-Kirschbaum,K. von Auer,Silke Jobst,F. Kaspers,Clemens Kirschbaum +7 more
TL;DR: Early morning cortisol levels can be a reliable biological marker for the individual's adrenocortical activity when measured repeatedly with strict reference to the time of awakening, in contrast to single assessments at fixed times.

Maternal care during infancy regulates the development of neural systems mediating the expression of fearfulness in the rat
Christian Caldji,Beth Tannenbaum,Shakti Sharma,Darlene D. Francis,Paul M. Plotsky,Michael J. Meaney +5 more
TL;DR: It is suggested that maternal care during infancy serves to "program" behavioral responses to stress in the offspring by altering the development of the neural systems that mediate fearfulness.
Journal ArticleDOI
Limbic system mechanisms of stress regulation: hypothalamo-pituitary-adrenocortical axis.
TL;DR: The influence of the limbic system on the HPA axis is likely the end result of the overall patterning of responses to given stimuli and glucocorticoids, with the magnitude of the secretory response determined with respect to the relative contributions of the various structures.

The cortisol awakening response (CAR): Facts and future directions
TL;DR: It is hypothesized that the anticipation of the upcoming day is of major relevance for the magnitude of the cortisol awakening response, and considerations are addressed concerning the exact function of the CAR.
