13. Psoriasis severity and hypothalamic-pituitary-adrenal axis function: results from the CALIPSO study
Psoriasis is a chronic inflammatory disease that significantly impacts life quality, being associated with stress and mental disorders. We investigated whether the activity of the hypothalamic-pituitary-adrenal (HPA) axis was associated with psoriasis severity, daily life stress and anxiety, and depressive symptoms. In this ancillary study, which was part of

14. A review on the evidence of transgenerational transmission of posttraumatic stress disorder vulnerability
Objective: To understand the risks of posttraumatic stress disorder (PTSD) development in the next generation of PTSD patients, we conducted a review on the biological, but not genetic, evidence of transgenerational transmission of PTSD vulnerability. Methods: Pertinent articles published from 1985 to September 2011 were searched using online academic searc

15. Estresse precoce e alterações do eixo hipotálamo-pituitária-adrenal (HPA) na depressão. / Early Life Stress and alterations of the Hypothalamic-Pituitary-Adrenal (HPA) axis in depression.
Introduction: Several studies suggest that stress in early stages of development can induce persistent changes in the ability of the Hypothalamic-Pituitary-Adrenal (HPA) axis to respond to stress in adulthood. The imbalance of cortisol has been identified as a biological correlate of depressive disorders. These abnormalities seem to be related to changes in

16. Efeito do sumatriptano no teste da simulação de falar em público / Effect of sumatriptan in the simulated public speaking test.
O Teste da Simulação de Falar em Público (SFP) é um teste sensível a drogas que interferem com a neurotransmissão mediada por serotonina (5-HT), e algumas evidências sugerem que ele possa recrutar os mesmos sistemas neuronais envolvidos na fisiopatogenia do Transtorno do Pânico (TP). Diferentes fármacos que, direta ou indiretamente, modulam receptor

17. Gestacional protein restriction triggers hiperanxiety in adulthood due to changes in the bed nucleus of stria the terminalis (BNST) / Avaliação de parâmetros comportamentais e da estrutura tridimensional de neurônios do núcleo da estria terminal de ratos machos adultos expostos à restrição protéica gestacional
In developed and developing countries maternal and child malnutrition has obvious repercussions on the population health f. This is due to changes in ontogenetic development, linked to the manifestation of programmed changes in morphological and functional development of organs and systems. The fetal programming by malnutrition or protein deficiency leads to

18. Effect of social instigation and aggressive behavior on hormone levels of lactating dams and adult male Wistar rats
Among rodents, maternal aggression in the postpartum period represents a species-typical adaptation, but when aggressive behavior increases beyond this adaptive level, it can represent a model of excessive aggression. This study assessed the neuroendocrine response of lactating rats and socially instigated male rats. The aim of the present study was to asses

19. Early life stress, HPA axis, and depression
Considerable evidence from various studies suggests a preeminent role for early adverse experiences in the development of psychopathology, especially depression. The most recent studies reviewed herein suggest that early life stressors are associated with an increased risk for mood disorders in adulthood. This review examines the emerging literature on the r

20. Defense-related emotions in humans
The study of the role of serotonin in anxiety has led to the view that this neurotransmitter enhances anxiety, but inhibits panic. Validation of this hypothesis has been made using two experimental procedures that increase anxiety in human volunteers. One is classical conditioning of the skin electrical conductance response, which is assumed to represent anx

21. Maternal undernutrition and the offspring kidney: from fetal to adult life
Maternal dietary protein restriction during pregnancy is associated with low fetal birth weight and leads to renal morphological and physiological changes. Different mechanisms can contribute to this phenotype: exposure to fetal glucocorticoid, alterations in the components of the renin-angiotensin system, apoptosis, and DNA methylation. A low-protein diet d

22. The hypothalamic-pituitary-adrenal axis in anxiety and panic
This review article focuses on the differential activation of the hypothalamic-pituitary-adrenal (HPA) axis in generalized anxiety and panic. The results of experimental studies that assayed adrenocorticotropic hormone, cortisol and prolactin show that real-life panic attacks as well as those induced by selective panicogenic agents, such as lactate and carbo

23. Cortisol and 17-a-hydroxy-progesterone levels in infants with refractory hypotension born at 30 weeks of gestation or less
Refractory hypotension is frequent in very low-birth weight infants, whose hypothalamic-pituitary-adrenal axis has been suggested to be immature. The objective of the present study was to evaluate basal cortisol and 17-α-OH-progesterone in the first 36 h of life in preterm infants with and without refractory hypotension (mean arterial blood pressure below t

24. Central actions of glucocorticoids in the control of body fluid homeostasis: Review
The involvement of the hypothalamic-pituitary-adrenal axis in the control of body fluid homeostasis has been extensively investigated in the past few years. In the present study, we reviewed the recent results obtained using different approaches to investigate the effects of glucocorticoids on the mechanisms of oxytocin and vasopressin synthesis and secretio
