Salivary Uric Acid May Be Associated with Cardiovascular Health Risks in African Americans
Salivary uric acid: Associations with resting and reactive blood pressure response to social evaluative stress in healthy African Americans. Author: Woerner J, et al. (2018), Psychoneuroendocrinology. ABSTRACT: High levels of uric acid are associated with greater risk of stress-related cardiovascular illnesses that occur disproportionately among African Americans. Whether hyperuricemia affects biological response to acute stress remains largely […]
Salivary Cortisol and Alpha-Amylase Connection in Mother-Infant Interactions
Ecologically salient stressors and supports and the coordination of cortisol and salivary alpha-amylase in mothers and infants. Author: Hibel LC, et al. (2018), Physiology and Behavior. ABSTRACT: This study examines the integration of the two main branches of the stress response system: the autonomic nervous system (via salivary alpha-amylase, sAA) and the hypothalamic-pituitary-adrenal axis (via cortisol). Mothers (n = 117) were […]
Salivary Stress Biomarkers as Tools for Determining Stress Adaptability and Resilience
Measuring Resilience to Operational Stress in Canadian Armed Forces Personnel. Authors: Hellewell SC & Cernak I (2018), J Trauma Stress. ABSTRACT: Adaptability to stress is governed by innate resilience, comprised of complex neuroendocrine and immune mechanisms alongside inherited or learned behavioral traits. Based on their capacity to adapt, some people thrive in stressful situations, whereas others […]
Relationship Between Salivary Cytokines and Household Fear of Deportation in Mexican-Origin Families
Household fear of deportation in relation to chronic stressors and salivary proinflammatory cytokines in Mexican-origin families post-SB 1070 Author: Martínez AD, et al. (2018), SSM – Population Health. ABSTRACT: Sociologists recognize that immigration enforcement policies are forms of institutionalized racism that can produce adverse health effects in both undocumented and documented Latinos and Mexican-origin persons in […]
Salivary Stress Biomarkers May be a Useful Tool for Determining the Risk of Stress Maladaptation
Measuring Resilience to Operational Stress in Canadian Armed Forces Personnel. Author: Hellewll SC & Cernak I. (2018), J Trauma Stress. ABSTRACT Adaptability to stress is governed by innate resilience, comprised of complex neuroendocrine and immune mechanisms alongside inherited or learned behavioral traits. Based on their capacity to adapt, some people thrive in stressful situations, whereas […]
Salivary DHEA-S, Cortisol show emotional & neuroendocrine response in relation to Telomere Length
Telomere Length and Procedural Justice Predict Stress Reactivity Responses to Unfair Outcomes in African Americans. Author: Lucas T, et al. (2017), Psychoneuroendocrinology Highlights TL predicts how psychosocial factors influence acute stress responses. Stress resiliency reflects telomere and procedural justice congruence. Considering TL as a predictor can advance understanding of racial health disparities. View Abstract Keywords: […]
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 […]
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 […]
Salivary uric acid modulates stress-related hippocampal activity
The 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 […]
Cardiovascular health disparities and psychosocial factors that influence stress reactivity
A Preliminary Experimental Examination of Worldview Verification, Perceived Racism, and Stress Reactivity in African Americans Author: Lucas, et al (2016), Health Psychology This preliminary examination considers how experiencing injustice can affect perceived racism and biological stress reactivity among African Americans. Guided by worldview verification theory, it was hypothesized that responses to receiving an unfair outcome […]
In utero infant’s stress response system impacted by mother’s psychological & physiological state
Developmental origins of infant stress reactivity profiles: A multi-system approach. Author: Rash JA, et al (2016), Developmental Psychobiology This study tested the hypothesis that maternal physiological and psychological variables during pregnancy discriminate between theoretically informed infant stress reactivity profiles. The sample size included 254 women and their infants. Maternal mood, salivary cortisol, respiratory sinus arrhythmia […]
