Lower cortisol response in high-resilient caregivers of people with autism: the role of anger
2016
Caring for an offspring with an autism spectrum disorder (ASD) has been related to high stress levels and health disturbances. However, a protective effect against these negative health outcomes has been described in high-resilient caregivers. In this context, the main aim of the present study was to assess the association between resilient coping and cortisol response to acute stress in caregivers of people with ASD. Furthermore, the study aimed to explore the mediating role of anger in this association. We exposed 40 caregivers of people with ASD to an acute psychosocial stressor in the laboratory. Salivary cortisol samples were obtained before, during, and after the stressor. Resilient c…
Morning and evening type: The cortisol awakening response in a sleep laboratory.
2019
Abstract Background Earlier evidence indicated an association between chronotype and the cortisol awakening response (CAR). However, these earlier data were collected without objective control for participant compliance being available, which, following recent guidelines, is considered critical for ensuring data validity. Here, we are seeking to replicate these earlier findings within a well-controlled sleep laboratory set up. Methods The sample consisted of 103 young males, including 12 participants defined as ‘evening’ (MEQ 59) types. All participants slept for one night in a sleep laboratory and were wakened at 6:30 AM the next morning. Saliva samples for the assessment of the CAR were…
Testosterone and cortisol release among Spanish soccer fans watching the 2010 World Cup Final
2012
This field study investigated the release of testosterone and cortisol of a vicarious winning experience in Spanish fans watching the finals between Spain and the Netherlands in the 2010 FIFA World Cup Soccer. Spanish fans (n = 50) watched the match with friends or family in a public place or at home and also participated in a control condition. Consistent with hypotheses, results revealed that testosterone and cortisol levels were higher when watching the match than on a control day. However, neither testosterone nor cortisol levels increased after the victory of the Spanish team. Moreover, the increase in testosterone secretion was not related to participants' sex, age or soccer fandom, b…
Modification of Diurnal Cortisol Secretion in Women’s Professional Basketball. A Pilot Study
2021
Elite basketball training causes high levels of physiological stress, which can lead to negative physiological disorders in female athletes. The aim of this study was to establish the impact of physical activity on the rhythm of salivary cortisol secretion in elite female basketball players over one week. The population sample included 9 women professional basketball players. The control group was made up of 9 women who did not do any exercise. Saliva samples were collected from all participants at 9:00 a.m. and 11:00 p.m. on training days. Samples from the basketball group showed a significantly higher cortisol secretion. Moreover, from the second night, the pattern of cortisol secretion o…
Effects of Trimipramine on Sleep EEG, Penile Tumescence and Nocturnal Hormonal Secretion
1989
Sleep EEG, nocturnal penile tumescence (NPT) and nocturnal endocrine activity were studied in 3 male control subjects during placebo, under trimipramine (TR) and after withdrawal. TR did not change the sleep structure. NPT activity tended to increase under TR. Nocturnal plasma cortisol levels decreased markedly while the early morning rise of cortisol appeared delayed under 200 mg TR. After withdrawal the changes of the cortisol secretion rebounded. Nocturnal secretion of GH, testosterone, LH and FSH remained unaffected, but plasma prolactin levels increased under TR and returned to normalcy after cessation. Our data illustrate that the neurobiological effects of TR are different from those…
The Divergent Effect of Insulin-Like Growth Factor Binding Protein (IGFBP) - 1 on IGF-induced Steroidogenesis in Bovine Adrenocortical Cells is not d…
2007
In previous studies we have shown that insulin-like growth factor (IGF)-II stimulates basal as well as ACTH-induced cortisol secretion from bovine adrenocortical cells more potently than IGF-I. The steroidogenic effect of both, IGF-I and IGF-II, is mediated through the IGF-I receptor and modified by locally produced IGF binding proteins. Further studies demonstrate that bovine adrenocortical cells do synthesize IGFBP-1 to -4 and that their secretion is regulated differentially by IGFs and ACTH. Since IGFBP-1 selectively is induced 3- to 4- fold by ACTH, the aim of the following studies was to evaluate the effect of IGFBP-1 on IGF-induced cortisol secretion from bovine adrenocortical cells i…
Congenital adrenal hypoplasia and hearing loss. A case report
1995
We report on the diagnostics, the therapeutics and the follow-up (to 3 years and 5 months) of a newborn affected by X-linked congenital adrenal hypoplasia. After the beginning of substitute hormonal therapy, the patient underwent periodical clinical examinations, with particular attention to the growth, and laboratory tests, which monitored the hormonal pattern. This experience points out the diagnostic role of low maternal levels of urinary estriol during pregnancy and the importance of a prolonged follow-up, so as to discover associated pathologies as early as possible. In our case, in fact, the study of auditory brainstem responses enabled us to recognize a mild transmission hearing loss…
Dietary Intake, Serum Hormones, Muscle Mass and Strength During Strength Training in 49 - 73-Year-Old Men
2007
Effects of dietary intake on serum hormones, muscle cross-sectional area (CSA) and strength during strength training were studied in two groups of men: 1) strength training + nutritional counseling (n = 22, 59.1 +/- 6.1 yrs), and 2) strength training (n = 23, 58.5 +/- 7.1 yrs). Both groups performed strength training twice a week for 21 weeks. Counseling increased carbohydrate (p < 0.01) and fiber intake (p < 0.001) and polyunsaturated/saturated fat-ratio (p < 0.05) and decreased fat intake (p < 0.01). Muscle strength and CSA increased by 16 - 20 % and by 5.4 - 5.9 % in both groups (p < 0.001). Changes in protein content of diet correlated with the changes in the acute postexercise concentr…
Effects of Short- and Long-term Ultraviolet B Irradiation on the Immune System of the Common Carp (Cyprinus carpio)¶
2005
Carp (Cyprinus carpio) were repeatedly exposed to 0, 60, 120 and 240 mJ/cm2 ultraviolet B (UVB) radiation three times in 1 week (short-term exposure) or 12 times in 4 weeks (long-term exposure). The effect of UVB on the functioning of the carp immune system was studied on day 2 after the final irradiation. After short-term UVB exposure, the whole-blood respiratory burst and cytotoxic activity were markedly enhanced, with parallel responses in both the number of circulating granulocytes and in the plasma cortisol concentration of the fish. These changes were not detectable after long-term exposure. The respiratory burst by head kidney granulocytes was suppressed dose dependently after both e…
The effects of glucocorticoids on thymidine kinase and nucleoside phosphotransferase during development of chicken embryo retina.
1983
AbstractThymidine kinase in chick embryo retina reaches its highest values on the 8–10th day of development, then declines reaching the lowest value at hatching. The rate of DNA synthesis essentially follows this activity while, in contrast, nucleoside phosphotransferase increases progressively during development. Glucocorticoids at 5 × 10−6M lower the level of thymidine kinase in isolated retinas of chick embryo. The most effective steroid was hydrocortisone. The effect was observed in retinas from 8–18-day-old chick embryo and, except on the 18th day, was always of the same magnitude. We suggest that a glucocorticoid can be the natural factor responsible for the marked fall in thymidine k…
