Understanding The Role Of Nutritional Stress In The Adult And Developing Zebra Finch
… the effects NS on females are still unclear. The hypothalamic-pituitary-adrenal axis (HPA) has been implicated in this process. However, evidence directly linking HPA functioning to the deficits due to NS have inconsistently shown elevations in CORT. Additionally, the effects of early NS on the …

Stress And Social Relationships: The Role Of Corticosterone In The Formation And Maintenance Of Pair Bonds In The Monogamous Zebra Finch (taeniopygia Guttata)
… rodents, suggest that activation 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 …

The Effect of Increased Sleep on the Circadian Rhythm of Salivary Cortisol Concentrations
<p>Cortisol is a salivary marker for the hypothalamic-pituitary-adrenal axis (HPA) component of the stress response. The activity of the HPA demonstrates a circadian rhythm. It is well known that sleep deprivation increases cortisol concentrations. In this study, we looked at the effect of an …

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
… zone. Salivary cortisol, a surrogate 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. …

The FitzHugh-Nagumo model dynamics with an application to the hypothalamic pituitary adrenal axis
… cortisol secretion, which is controlled by the hypothalamic pituitary adrenal axis (HPA). Existing mathematical models for cortisol secretion do not include the entire cortisol secretion process, from the neural firing of cortopin releasing hormone(CRH) in the hypothalamus to cortisol secretion …

The Role of the Pituitary-Adrenal Axis in G-CSF Therapy after Neonatal Hypoxia-Ischemia
… reports indicate that the activity of the hypothalamic-pituitary-adrenal axis (HPA) as measured by the increased level of adrenocorticotropic hormone (ACTH), and corticosterone is increased after a brain insult. These hormones are the effectors secreted respectively by the pituitary and …

Role of the Pituitary-Adrenal Axis in G-CSF Therapy after Neonatal Hypoxia-Ischemia
Several reports indicate that the activity of the hypothalamic-pituitary-adrenal axis (HPA) as measured by the increased level of adrenocorticotropic hormone (ACTH), and corticosterone is increased after a brain insult. These hormones are the effectors secreted respectively by the pituitary and …

The activity and functioning of the hypothalamic-pituitary-adrenal axis of the red deer stag (cervus elaphus)
The activity and functioning of the HPA axis was investigated in red deer stags under basal and stress induced conditions. In order to overcome the confounding effects of stress inherent in standard methods of blood collection, a portable remote blood sampling device (“DracPac”) was developed and …
