Determining the appropriate statistical approach for effective analysis of hormone ratios
November 21, 2016How to use and interpret hormone ratios Author: Sollberger S, et al (2016), Psychoneuroendocrinology. Hormone ratios have become increasingly popular throughout the neuroendocrine literature since they offer a straightforward way to simultaneously analyze the effects of two interdependent hormones. However, the analysis of ratios is associated with statistical and interpretational concerns which have not been […]

Salivary uric acid modulates stress-related hippocampal activity
November 3, 2016The hippocampal response to psychosocial stress varies with salivary uric acid level Author: Goodman AM, et al (2016), Neuroscience. Uric acid is a naturally occurring, endogenous compound that impacts mental health. In particular, uric acid levels are associated with emotion-related psychopathology (e.g., anxiety and depression). Therefore, understanding uric acid’s impact on the brain would provide […]
Study demonstrates combined effects of salivary cortisol & DHEA-S in predicting depressive symptoms
October 24, 2016Concurrent and prospective associations between HPA axis activity and depression symptoms in newlywed women Author: Ge F, et al (2016), Psychoneuroendocrinology. We investigated the extent to which individual differences in activity of the hypothalamic pituitary adrenal axis (HPA) are associated with depressive symptoms among newlywed couples.
