Transgenerational Effects of Synthetic Glucocorticoids on Offspring Behaviour and HPA Development in Guinea Pigs
… alterations in hypothalamic-pituitary-adrenal (HPA) function and stress-associated behaviours in first generation (F1) offspring. Emerging studies in animals determined that sGC results in transmission of HPA and behavioural effects to the next generation (F2) of offspring, but no study has …

Role of testosterone in mediating prenatel ethanol effects on hypothalamic-pituitary-adrenal activity in male rats
… of the hypothalamic-pituitary-adrenal (HPA) and -gonadal (HPG) axes. E rats show HPA hyperresponsiveness to stressors and altered reproductive function in adulthood. Importantly, prenatal ethanol differentially alters stress responsiveness in adult males and females, raising the …

Stress And Social Relationships: The Role Of Corticosterone In The Formation And Maintenance Of Pair Bonds In The Monogamous Zebra Finch (taeniopygia Guttata)
… of the hypothalamic-pituitary-adrenal axis (HPA) in males increases attraction for females. Across species, females are understudied, but evidence from the prairie vole suggests HPA activation impairs formation of partner preference, the first step in establishing a pair bond. Across taxa …

Circadian activation of the hypothalamic-pituitary-adrenal axis may affect central, but not peripheral, effect of lithium in conditioned taste aversion learning in rats
Activation of the hypothalamic–pituitary–adrenal (HPA) axis has been implicated in conditioned taste aversion (CTA) learning induced by lithium chloride. This study investigated if circadian activation of the HPA axis affects the lithium-induced CTA formation. The pairing of conditioned stimulus …

The Relationship of Level of Traumatic Exposure, Perceived Stress, and Resilience with Salivary Cortisol and Salivary Alpha-Amylase Diurnal Rhythm in Palestinian Children 10-12 Years Exposed to Chronic War Violence
… marker of hypothalamic-pituitary-adrenal axis (HPA) activity, and salivary alpha-amylase, a surrogate marker of sympathetic nervous system (SNS), have been used to explore relationships of studies psychoneurobiological factors and processes related to stress. This study is exceptional in its …

An Epidemiological Study of Exhaustion in the Context of Chronic stress. Concept, Cortisol, Causes and Consequences
… in relation to depression and anxiety; HPA activity in exhaustion; associations with psychosocial work stressors; and significance for onset of a “stress-related disease”, i.e. cardiac disease. Two study populations were used. For Papers I, III, and IV, analyses were performed on data …

Alterations in adult behavior as a result of early life manipulations
… stress on the hypothalamic-pituitary-adrenal (HPA) axis, central serotonergic markers and social status of male rats. As adults, prenatal stress was not associated with altered basal corticosterone (CORT) or CORT response to acute restraint. However, fewer serotonergic neurons were observed …

Stress Reactivity Patterns in Breast Cancer Survivors and the Implications of Various Psychosocial Factors
… comprises the hypothalamic-pituitary-adrenal (HPA) and the sympathetic-adrenal-medullary (SAM) axes. The two operate synergistically to regulate metabolic and biological processes, maintain homeostasis, and manage physiological responses towards various environmental challenges, known as …

Effect of selection for interspecific behavior on stress and conspecific behavior in tame and aggressive foxes
… as a proxy for hypothalamic-pituitary-adrenal (HPA) axis activity in tame and aggressive foxes. Glucocorticoid measurement from fecal samples is a practice that has been validated in other canids, such as coyotes and dogs. Fecal samples were collected six month-old tame and aggressive male foxes …
