The effects of power posing on neuroendocrine levels and risk-taking.

Background: The current study attempted to replicate the original findings regarding the effects of power posing on testosterone and cortisol levels, risk-taking behavior, and perceived power. We further extended the investigation by testing the effect of power posing on estradiol and progesterone levels.

Methods: A sample of 92 young adults (30 males; 32 females taking oral contraceptives; and 30 females not taking oral contraceptives who were in their midluteal phase) were randomly assigned to high-power-pose or low-power-pose conditions and asked about their feelings of power.

Normocalcemic primary hyperparathyroidism is an early stage of primary hyperparathyroidism according to fibroblast growth factor 23 level.

Introduction: Normocalcemic primary hyperparathyroidism is a variant of primary hyperparathyroidism with consistently normal albumin-adjusted or free-ionized calcium levels. It may be an early stage of classic primary hyperparathyroidism or could represent primary kidney or bone disorder characterized by permanent elevation of PTH level.

Aim Of The Study: The study aims to compare the FGF-23 levels in patients with PHPT, NPHPT, and normal calcium and PTH levels.

State Anxiety and Procrastination: The Moderating Role of Neuroendocrine Factors.

Procrastination is prevalent among students, as well as the general population, and has negative impacts on various domains. Several models aimed to understand factors associated with procrastination, with some suggesting that anxiety plays a significant role. Biological factors have been shown to contribute to individual differences in procrastination; however, little attention has been paid to the role of neuroendocrine factors on procrastination.

Association between betamethasone levels and respiratory distress syndrome in preterm births: A prospective cohort study.

The recommended fixed dosage of betamethasone for pregnancies at risk of preterm birth was determined in the 1970s, regardless of gestational age (GA), number of fetuses, and maternal weight. We aimed to examine the association between maternal and neonatal betamethasone serum levels and neonatal respiratory distress syndrome (RDS) and to examine whether levels correlate with maternal weight, GA, or number of fetuses. A prospective study was conducted at a single academic medical center between August 2016 and February 2019.

The Role of Endocrine Stress Systems and Sex Hormones in the Enhancing Effects of Stress on Mental Rotation Capabilities.

The possible effects of stress and neurobiological stress mechanisms on visuospatial abilities remain largely unknown. In the current study, we examined the combined effect of sex hormones and both the hypothalamic-pituitary-adrenal axis (HPA-A) and the sympathetic nervous system (SNS) on stress-induced changes in visuospatial performance. A total of 107 participants completed a mental rotation task and were subsequently exposed to either to the Trier social stress test (TSST) or to a control condition before completing the mental rotation task again.

Interactive role of endocrine stress systems and reproductive hormones in the effects of stress on declarative memory.

The effects of stress on memory performance, and the neuroendocrine mechanisms mediating such effects, are not well understood. Given the interrelationship between reproductive hormones and both the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal axis (HPA-A), we examined their combined effect on stress-induced modulation of declarative memory. Before and after exposure either to the Trier Social Stress Test (TSST) procedure or to a non-stress condition, 112 participants completed the Rey Auditory Verbal Learning Test.

Gonadal hormones modulate the HPA-axis and the SNS in response to psychosocial stress.

Exposure to stress activates both the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). A growing body of research points to the contribution of sex hormones (testosterone, estrogen, and progesterone), the end products of the hypothalamus-pituitary-gonadal (HPG) axis, in modulating stress reactivity. The present study aimed at investigating the potential modulating role of sex hormones on HPA and SNS reactivity to psychosocial stress.
