Nonhuman primates mirror human early life adversity & salivary cortisol/alpha-amylase responses
Effects of early life adversity on cortisol/salivary alpha-amylase symmetry in free-ranging juvenile rhesus macaques. Author: Petrullo LA, et al (2016), Horm Behav. Early life adversity (ELA) affects physiological and behavioral development. One key component is the relationship between the developing Hypothalamic-Pituitary-Adrenal (HPA) axis and the Sympathetic Nervous System (SNS). Recent studies suggest a relationship between […]
Sex hormone variations in both sexes may be important when investigating stress physiology
Sex hormones adjust “sex-specific” reactive and diurnal cortisol profiles. Author: Author: Juster, et al (2015), Psychoneuroendocrinology Sex differences in stress hormone functions are presumed to depend on sex hormones. And yet, surprisingly few psychoneuroendocrine studies actually assess within-sex variations of testosterone, estradiol, and progesterone when investigating sex-specific activities of the hypothalamic-pituitary-adrenal axis. In this methodological […]
Salivary bioscience enables anabolic hormone profiles in elite military men
Anabolic hormone profiles in elite military men. Author: Taylor MK, et al (2016), Steroids. This study recently characterized the awakening responses and daily profiles of the catabolic stress hormone cortisol in elite military men. Anabolic hormones follow a similar daily pattern and may counteract the catabolic effects of cortisol. This companion report is the first […]
Salivary testosterone / salivary cortisol ratio may predict a team player’s social popularity
Long-term stability of diurnal salivary cortisol and alpha-amylase secretion patterns Author: Ponzi D, et al (2016), Psychoneuroendocrinology This study tested whether testosterone and cortisol interacted in predicting social network centrality. The sample size consisted of 41 male rugby athletes from Burnaby, Canada. Using social network analysis (SNA), three measures of centrality were investigated: popularity (i.e., […]
Differences in Salivary Cortisol and Testosterone may guide social network dynamics
Cortisol and testosterone associations with social network dynamics Author: Kornienko, et al (2015), Psychoneuroendocrinology. This study integrates behavioral endocrinology and network science to explore links between hormones and social network dynamics. Specifically, we examine how cortisol (C) and testosterone (T) are associated with creation of new friendships and maintenance of existing friendships. A collegiate marching […]
General conclusions from extant research on the association between cortisol regulation and PMS/PMDD
A lack of consistent evidence for cortisol dysregulation in premenstrual syndrome/premenstrual dysphoric disorder (PMS/PMDD) Author: Kiesner J, et al (2015), Psychoneuroendocrinology A review on the association between PMS/PMDD and cortisol levels and its reactivity examined three types of studies: correlational studies, environmental-change studies, and pharmacological-challenge studies. A total of 38 articles were selected based on […]
