1. Modulation of neuropeptide Y levels is impaired in crack withdrawal patients
Abstract Introduction The dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has a key role in drug addiction susceptibility. In addition to the well-known relationship between cortisol and the HPA axis, other molecules are involved with stress response and could modify the HPA activation, such as the neuropeptide Y (NPY), which has anxiolytic

3. Is biochemical hypoglycemia necessary during an insulin tolerance test?
ABSTRACT Objective The insulin tolerance test (ITT) has been accepted as the gold standard test for assessing the integrity of the growth hormone (GH) – insulin-like growth factor (IGF-1) axis and the hypothalamic-pituitary-adrenal (HPA) axis. The goal of the test is to achieve clinical and biochemical hypoglycemia at a blood glucose level ≤ 40 mg/dL t

4. The effect of antidepressant treatment on the HPA axis, changes in depression score and serum levels of TNF-α in depressed infertile women
Abstract Objectives This study aimed to explore the effect of antidepressant treatment on the HPA axis, changes in depression score, and serum levels of TNF-α in depressed infertile women. Methods In this randomized controlled trial research, 60 infertile women who had undergone in vitro fertilization (IVF) treatment with depression scores between 16-47 w

5. Stress, strain, and pregnancy outcome in postpartum cows
Abstract Stress affects the productivity and fertility of cattle. Stress causes strain and individual animals experience different amounts of strain in response to the same amount of stress. The amount of strain determines the impact of stress on fertility. Typical stresses experienced by cattle include environmental, disease, production, nutritional, and ps

6. Opioids in the immune system: from experimental studies to clinical practice
RESUMO INTRODUÇÃO: Os opioides interagem com ambos os sistemas imunes, inato e adaptativo, através de efeitos diretos sobre os receptores dos opioides localizados nas células imunes. As pesquisas neste assunto têm fornecido evidência da influência dos opioides sobre a resposta imune associada ao estresse cirúrgico. Os efeitos imunológicos dos opioi

7. Different levels of brain-derived neurotrophic factor and cortisol in healthy heavy smokers
Studies suggest that brain-derived neurotrophic factor (BDNF) and the hypothalamic-pituitary-adrenal (HPA) axis modulate dopaminergic activity in response to nicotine and that the concentrations of BDNF and cortisol seem to be dependent on the amount and duration of smoking. Therefore, we investigated BDNF and cortisol levels in smokers ranked by daily cigar

8. Salivary cortisol and α-amylase: subclinical indicators of stress as cardiometabolic risk
Currently, the potential for cardiovascular (CV) stress-induced risk is primarily based on the theoretical (obvious) side effects of stress on the CV system. Salivary cortisol and α-amylase, produced respectively by the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic-adrenomedullary (SAM) system during stress response, are still not included i

9. Hair cortisol in drug-naïve first-episode individuals with psychosis
Objectives: To compare hair cortisol concentrations (HCC) in drug-naïve first-episode psychosis (FEP) patients and healthy controls and to investigate the correlations between HCC and psychopathology. Methods: Twenty-four drug-naïve FEP patients and 27 gender- and age-matched healthy control subjects were recruited. The Structured Clinical Interview for

10. 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

11. Avaliação do funcionamento do eixo HPA em deprimidos por meio de medidas basais: revisão sistemática da literatura e análise das metodologias utilizadas
Objetivo Realizar revisão sistemática da literatura para conhecer a atividade do eixo hipotálamo-pituitária-adrenal (HPA) em deprimidos considerando-se as medidas basais dos hormônios e analisar criticamente as metodologias utilizadas. Métodos Foi realizada busca de artigos nas bases de dados PubMed e SciELO. Na primeira base de dados, introduziram-se

12. 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
