TL;DR: The results suggest that diurnal profiles of salivary alpha-amylase are relatively robust against momentary influences and therefore may prove useful in the assessment of sympathetic nervous system activity.

TL;DR: This study assesses the cortisol rise after awakening on 6 consecutive days to conclude that the CAR of a single day is determined to a great extent by situational factors and only for a small proportion by trait factors and from two to six days are necessary to achieve reliable trait measures.

TL;DR: The data support the hypothesis that elevated secretion of glucocorticoids may be associated to behavioural and cognitive deficits in MS rats and suggest the possible involvement of the noradrenergic system in cognitive impairments mediated by glucoc Corticoids in the MS model.

TL;DR: It is demonstrated that continuous administration of IL-1ra via osmotic minipumps during prenatal development disrupt memory performance in adult mice, suggesting thatIL-1 plays a critical role not only in the formation of hippocampal-dependent memory but also in normal hippocampal development.

TL;DR: It is concluded that the cortisol increase after awakening is a response to morning awakening that is distinct from the circadian rise in hypothalamo-pituitary-adrenal (HPA) activity in the morning hours.

TL;DR: Findings imply a direct protective effect of touch on stress-related neurobiological systems as a possible underlying mechanism of health beneficial effects of positive couple interaction.

TL;DR: The results provide the first evidence in favor of a functional dissociation between the brain structures that underlie cytokine-induced sickness behavior and cytokin-induced depressive-like behavior, and provide important cues about the neuroanatomical brain circuits through which cytokines could have an impact on affect.

TL;DR: The findings from this current study add to the growing body of evidence demonstrating that 2D:4D is a suitable tool to study the effects of prenatal androgenization on human behavior and cognition.

TL;DR: On the whole, elite sportsmen showed reduced reactivity to the psychosocial stressor, characterized by lower adrenocortical, autonomic, and psychological stress responses, suggesting that physical activity may provide a protective effect against stress-related disorders.

TL;DR: Improvements in caregiving following early adversity appear to have the potential to reverse or prevent disruptions in HPA axis functioning.

TL;DR: The idea of the usefulness of the PRS rat as an interesting animal model for the design and testing of new pharmacologic strategies in the treatment of stress-related disorders is reinforced.

TL;DR: It is suggested that social isolation induces behavioral and neuroendocrine responses relevant to depression in male and female prairie voles, although neuro endocrine responses in females may be especially sensitive to isolation.

TL;DR: The findings suggest that high cortisol reactivity to stress promotes food intake, and the eating style variables of restraint, emotional eating, external eating and disinhibition were more strongly associated with snack intake in high reactors than in low reactors.

TL;DR: A significant negative correlation between oxytocin and the scored symptoms depression and anxiety was showed and OT may contribute to the dysregulation of the HPA system in major depression.

TL;DR: MS has long-lasting and differential effects on adult intermale and maternal aggression in C57BL/6 mice, and represents a promising animal model to reveal underlying mechanisms of aggressive behavioral dysfunctions associated with early life stress.

TL;DR: Higher trait EI scores were associated with significantly lower reactivity to stress at both psychological and biological levels, and had incremental validity to predict stress reactivity over and above social desirability, alexithymia and the five-factor model of personality.

TL;DR: A synergistic relationship between depression, cortisol and metabolic syndrome is suggested, suggesting hypercortisolemic depression may constitute a specific risk group for the metabolic syndrome.

TL;DR: It is concluded that positive affect is related to biological responses in the laboratory and everyday life that may be health protective and substantially stronger when positive affect was assessed by aggregating EMA samples than with questionnaire measures.

TL;DR: The data supports the possibility that postpartum depression may be associated with a dysregulated HPA axis and possible depressed cellular immunity.

TL;DR: A novel chronic social stress paradigm in male mice during adolescence results in persistent alterations of hypothalamus-pituitary-adrenal axis function and behavior, which are reversible by pharmacological treatment and allows to investigate the interaction of genetic susceptibility and environmental risk factors.

TL;DR: Data show that stress hormones can increase DNA damage and transformation and alter transcriptional regulation of the cell cycle.

TL;DR: The data suggest that enhanced cortisol suppression to dexamethasone is related to trauma exposure and not specifically to PTSD, and suggests that a flattened ACR may be a result of clinical symptoms.

TL;DR: Immediate posttraumatic alterations in neuroendocrine or inflammatory factors-increased evening salivary cortisol and/or increased morning serum IL-6 concentrations-are involved in subsequent PTSD development in children and adolescents.

TL;DR: The hypothesis of a generally decreased responsiveness of the stress system is supported by showing reduced skin conductance responses as well as reduced affective startle modulation in anxiety-prone participants after administration of testosterone.

TL;DR: Exposure to prenatal stress results in long-lasting behavioural and neuroendocrine alterations in the female offspring, which are manifested during the lactation period, and implicates PS as a potential risk factor for the development of postpartum mood disorders.

TL;DR: Effective psychotherapy for PTSD may alter dysregulations in the Hypothalamus-pituitary-adrenal (HPA)-axis, but comorbid depressive symptoms should be taken into account.

TL;DR: In this paper, positive and negative social interactions can modulate the hypothalamic-pituitary-adrenal (HPA) axis and influence recovery from injuries and illnesses, such as wounds, stroke, and cardiac arrest.

TL;DR: It is concluded that in young adults without manifest psychiatric disorder, resilience was associated with developmental, biological, and cognitive measures which merit further investigation.

TL;DR: Data demonstrate that estrogen may elicit changes in emotional behavior through an endocannabinoid mechanism, and suggest that inhibition of FAAH represents a therapeutic target for anxiety and depression in women.

TL;DR: It is indicated that a psychological stress may induce an increase in plasma ghrelin levels in humans, and that the post-stress induced urge for uncontrolled eating is not acutely modulated by stress related elevations in gh Relin levels.
