The role of testosterone and age in impatient decision-making in boys
January 10, 2018Dissociable effects of age and testosterone on adolescent impatience Author: Laube C, et al. (2017), Psychoneuroendocrinology The onset of adolescence is associated with an increase in transgressive behaviours-from juvenile delinquency to substance use and unprotected sex-that are often attributed to increased impulsiveness. In the past, this increase was ascribed to “raging hormones”; more recently, to […]
Disorganized attachment in infants associated with elevated salivary CRP
August 2, 2017Increased levels of inflammation among infants with disorganized histories of attachment Author: Measelle JR, et al. (2017), Behavioural Brain Research Early life adversity is associated with adult elevations of inflammatory markers such as circulating levels of C-reactive protein (CRP). Few studies have examined inflammation levels during infancy nor the associations between sources of adversity and […]
Non-invasive oral fluid immunoassay for hepatitis E virus (HEV) infection
July 27, 2017Development of an oral fluid immunoassay to assess past and recent hepatitis E virus (HEV) infection Author: Pisanic N, et al. (2017), Journal of Immunological Methods BACKGROUND: Hepatitis E virus (HEV) infection causes significant morbidity and mortality worldwide, particularly among pregnant women. In clinical settings blood-based testing protocols are commonly used to diagnose HEV infection, […]
Childhood maltreatment affects cortisol and alpha-amylase stress reactivity
July 19, 2017Patterns of cortisol and alpha-amylase reactivity to psychosocial stress in maltreated women Author: Mielock AS, et al. (2017), Journal of Affective Disorders BACKGROUND: Childhood maltreatment can trigger enduring changes in major stress response systems, particularly in the context of major depressive disorder (MDD). However, the relative impact of maltreatment versus MDD on hypothalamic-pituitary-adrenal axis and […]
Differences in HPA axis activity are a function of age and cumulative risk
July 11, 2017Individual differences in the activity of the hypothalamic pituitary adrenal axis: Relations to age and cumulative risk in early childhood Author: Holochwost SJ, et al. (2017), Psychoneuroendocrinology This study examined individual differences in the function of the hypothalamic-pituitary-adrenal (HPA) axis with regard to age and cumulative risk during challenging laboratory tasks administered at 6, 12, […]
Association of salivary adiponectin with serum and inflammatory markers
June 30, 2017Adiponectin: Serum-Saliva Associations and Relations with Oral and Systemic Markers of Inflammation Author: Riis JN, et al. (2017), Peptides This study addresses gaps in our understanding about the validity and utility of using salivary adiponectin to index serum adiponectin levels. Matched blood and saliva samples were collected on a single occasion from healthy adults (n=99; […]
Adolescent appraisal of interparental conflict is reflected by stress reactivity
June 19, 2017Adolescent conflict appraisals moderate the link between marital conflict and physiological stress reactivity Author: Lucas-Thompson RG, et al. (2017), Journal of Research on Adolescence The goal of this study was to advance understanding of how adolescent conflict appraisals contribute uniquely, and in combination with interparental conflict behavior, to individual differences in adolescent physiological reactivity. Saliva […]
Variation in salivary cortisol and alpha-amylase rhythms over 24 months
May 25, 2017Long-term stability of diurnal salivary cortisol and alpha-amylase secretion patterns Author: Skoluda N, et al. (2017), Physiology & Behavio This study aimed to investigate long-term stability and variability of diurnal cortisol and alpha-amylase patterns. Diurnal cortisol and alpha-amylase secretion patterns were assessed on a single workday with three waves of measurement across a total time […]
Temperament predicts salivary cortisol and alpha-amylase in BASE jumpers
May 19, 2017Stress reactivity and personality in extreme sport athletes: The psychobiology of BASE jumpers Author: Monasterio E, et al. (2016), Physiology & Behavior This is the first report of the psychobiology of stress in BASE jumpers, one of the most dangerous forms of extreme sport. We tested the hypotheses that indicators of emotional style (temperament) predict […]
Douglas A. Granger, Ph.D., to Join DAACRO’s Scientific Advisory Board
May 17, 2017(May 17, 2017) With the addition of psychoneuroendocrinology researcher, Douglas A. Granger, Ph.D., DAACRO’s advisory board continues to cultivate a network of multi-disciplinary scientific experts, enabling access to key scientific knowledge that is required, but not often achieved through traditional Contract Research Organizations (CROs). DAACRO combines CRO standards with psychonneuroendocrine stress expertise, and further enhances [...]
