June 6, 2018The plasmatic and salivary levels of IL-1β, IL-18 and IL-6 are associated to emotional difference during stress in young male Author: La Fratta I, et al (2018), Sci Rep BACKGROUND: Saliva collection is considered a non-invasive method to detect inflammatory markers in response to emotional states within natural social contexts. Numerous studies have prompted an important […]
Salivary Secretory Immunoglobulin A: The impact of smoke exposure during and after pregnancy
Prenatal and postnatal cigarette and cannabis exposure: Effects on Secretory Immunoglobulin A in early childhood. Author: Molnar DS, et al. (2018), Neurotoxicol Teratol. BACKGRUOND: AIMS: Secretory Immunoglobulin A (SIgA) plays a critical role in immune functioning by preventing pathogens from adhering to epithelial mucosa. Most infectious agents enter the body via mucosal surfaces, thus SIgA […]
Call for Papers on Salivary Bioscience in Behavioral Medicine
May 29, 2018INTERNATIONAL JOURNAL OF BEHAVIORAL MEDICINE Letter of Intent Deadline: November 15, 2018 Facilitated by advances in salivary bioscience, great strides over the past several decades have been made in understanding how psychological and social factors “get under the skin.” Research utilizing salivary markers of hypothalamic-pituitary-adrenal axis activity, sympathetic nervous system activation, as well as other […]
High prestige in social groups increases salivary testosterone levels in men
May 23, 2018Prestige in a large-scale social group predicts longitudinal changes in testosterone. Author: Cheng JT, et al. (2018), J Pers Soc Psychol. BACKGROUND: In many social species, organisms adaptively fine-tune their competitive behavior in response to previous experiences of social status: Individuals who have prevailed in the past preferentially compete in the future, whereas those who […]

Research highlights multi-system perspective for motivation, adolescent depressive symptoms, and HPA axis activation
May 15, 2018An exploratory analysis of the joint contribution of HPA axis activation and motivation to early adolescent depressive symptoms. Author: Rudolph KD, et al (2018), Developmental Psychobiology BACKGROUND: This study examines the interactive contribution of the hypothalamic-pituitary-adrenal (HPA) axis and approach-avoidance motivation systems to longitudinal changes in depressive symptoms across the adolescent transition. In the summer […]
Links between salivary testosterone and aggressive behavior
May 10, 2018Testosterone and Proactive-Reactive Aggression in Youth: the Moderating Role of Harsh Discipline. Author: Chen FR, et al (2018), Journal of abnormal child psychology BACKGROUND: This study tests a biosocial model of the link between testosterone and proactive-reactive aggression in youth at varying levels of harsh discipline. Given that proactive aggression is used to gain power […]
Social Context of Psychosocial Processes During Adolescent Development and the Psychobiology of the Stress Response.
May 7, 2018Peer Networks, Psychobiology of Stress Response, and Adolescent Development Author: Kornienko, O, et al (2018), PLoS BACKGROUND: A consistent focus of research has been on understanding how social relationships shape the activity of the biological stress response system. Progress has been made in characterizing these dynamics at the level of the individual, but significantly less […]
Anticipation of fMRI leads to acute elevations in cortisol prior to scanning
May 2, 2018Anticipatory stress associated with functional magnetic resonance imaging: Implications for psychosocial stress research. Author: Gossett EW, et al (2018), International journal of psychophysiology BACKGROUND: Stress tasks performed during functional magnetic resonance imaging (fMRI) elicit a relatively small cortisol response compared to stress tasks completed in a traditional behavioral laboratory, which may be due to apprehension […]
