Lower BMI and uric acid in Mexican-origin families with greater fear of deportation
Household fear of deportation in Mexican-origin families: Relation to body mass index percentiles and salivary uric acid Author: Martinez AD, et al. (2017), American Journal of Human Biology OBJECTIVE: Fear of deportation (FOD) is a prevalent concern among mixed-status families. Yet, our understanding of how FOD shapes human health and development is in its infancy. […]
Reproducibility of salivary cortisol measurement across established-qualified laboratories
Measurement of cortisol in saliva: a comparison of measurement error within and between international academic‑research laboratories. Author: Calvi JL, et al. (2017), BMC Research Notes 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 […]
Variations in DHEA-S associated with health and maturation during adrenal development
Adrenal maturation, nutritional status, and mucosal immunity in Bolivian youth. Author: Hodges-Simeon CR, et al. (2017), American Journal of Human Biology OBJECTIVES: Humans-and several other apes-exhibit a unique pattern of post-natal adrenal maturation; however, the causes and consequences of variation in adrenal development are not well understood. In this study, we examine developmental and age-related […]
Traumatic childhood injuries related to changes in stress reactivity
Altered Stress System Reactivity After Pediatric Injury: Relation with Post-Traumatic Stress Symptoms Author: Ewing-Cobbs, et al. (2017), Psychoneuroendocrinology Research Article Highlights; HPA and ANS stress systems were dysregulated after nonintentional pediatric injury. HPA and ANS activity and regulation varied with age at injury and type of injury. Cortisol reactivity to social stress was attenuated after […]
The role of testosterone and age in impatient decision-making in boys
Dissociable 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
Increased 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
Development 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
Patterns 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
Individual 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
Adiponectin: 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
Adolescent 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
Long-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
Stress 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) 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 [...]
Salivary Cortisol variability is influenced by social characteristics of owner and dog
Psychobiological Factors Affecting Cortisol Variability in Human-Dog Dyads Author: Schöberl I, et al. (2017), PLOS One Stress responses within dyads are modulated by interactions such as mutual emotional support and conflict. We investigated dyadic psychobiological factors influencing intra-individual cortisol variability in response to different challenging situations by testing 132 owners and their dogs in a […]
