Cortisol pulsatility and its role in stress regulation and health
(Elsevier, 2004)
One of the classic characteristics of the human stress response is the wide inter-individual variation. Although there is much current interest in the genetic and environmental contributions to these differences, studies ...
Disordered Adrenocorticotropin Secretion in Women with Major Depression
(Endocrine Society, 2006-05)
Context: Major depression is accompanied by activation of the hypothalamic pituitary axis and evidence of abnormalities in circadian and ultradian hormone rhythms. In addition, diminished negative feedback of cortisol on ...
Sex Differences in the ACTH Response to 24H Metyrapone in Depression
(Elsevier, 2006-12)
Increased hypothalamic-pituitary adrenal (HPA) axis activation has been observed in major depression. Increased corticotropin-releasing hormone (CRH) is hypothesized to drive corticotropin (ACTH) secretion leading to ...
Saliva Cortisol in Posttraumatic Stress Disorder:
(Elsevier, 2004-08-01)
Background: Stress activates the hypothalamic–pituitary–adrenal (HPA) axis, so it was expected that posttraumatic stress disorder (PTSD) would be associated with activation of this axis; however, studies have found both ...
The pattern of growth hormone secretion during the menstrual cycle in normal and depressed women
(Blackwell, 2005)
Objective
Major depression is associated to altered hypothalamic pituitary function. Stress is linked to elevated cortisol as well as menstrual cycle disturbance; however, there is no known relationship between depression ...
Pulsatile luteinizing hormone disruption in depression
(Elsevier, 2004)
Two independent groups recently published data comparing pulsatile luteinizing hormone (LH) release between depressed and control women. Despite
similar populations and LH sampling frequency, they reached different ...
Anxious and Depressive Disorders and Their Comorbidity: Effect on Central Nervous System Noradrenergic Function
(Elsevier, 2004-12-01)
Background: Although comorbidity of anxiety with depression is common, investigations of physiologic abnormalities related specifically to comorbidity are rare. This study examined relationships of DSM-IV-defined depression, ...
Effect of Comorbid Anxiety Disorders on the HPA Axis Response to a Social Stressor in Major Depression
(Elsevier, 2004-12-01)
Background: Major depressive disorder (MDD) is often complicated by anxiety symptoms, and anxiety disorders occur in approximately 30% of mood cases. This study examined the influence of anxiety comorbidity on the ...
Interaction of Brain Noradrenergic System and the Hypothalamic-Pituitary-Adrenal (HPA) Axis in Man
(Elsevier, 2005-09-30)
Background: Numerous interactions between the brainstem locus coeruleus system and the HPA axis have been shown in experimental animals. This relationship is less well characterized in humans and little is known about the ...
Sex differences in Neuroendocrine and Neurotransmitter Systems
