The endocrine disrupting properties of bisphenol A (BPA) discharged to the environment have been newly identified by the European Chemicals Agency, increasing the need to assess the environmental endocrine disrupting potentials of its alternatives with which it shares close structural features. However, few investigations of the environmental endocrine disrupting functions of BPA analogs have been conducted to date. In this study, the endocrine disrupting effects of a BPA analog of bisphenol P (BPP) were investigated in the nonbiting midge (Chironomus tentans), a model organism in ecotoxicology...

BACKGROUND: The 2nd to 4th digit ratio (2D:4D) is regarded as a sexually dimorphic trait governed by prenatal testosterone (T) and estradiol exposure. However, relationships between the 2D:4D and adult sex hormone concentrations are inconsistent in females. Environmental contingencies (e.g., physical training) may provide a stronger basis for establishing these linkages, particularly if the relationships are plastic and not fixed. AIMS: To investigate associations between 2D:4D, training hours and salivary T (sal-T) measures in physically-active women...

Ashwagandha ( Withania somnifera) is a herb commonly used in Ayurvedic medicine to promote youthful vigor, enhance muscle strength and endurance, and improve overall health. In this 16-week, randomized, double-blind, placebo-controlled, crossover study, its effects on fatigue, vigor, and steroid hormones in aging men were investigated. Overweight men aged 40-70 years, with mild fatigue, were given a placebo or an ashwagandha extract (Shoden beads, delivering 21 mg of withanolide glycosides a day) for 8 weeks...

The influence of sex hormones on women's mate preferences has been an intensively discussed topic for more than a decade. Yet the extent to which levels of sex hormones, and testosterone in particular, influence women's mate preferences is unclear. Thus, the current study used multilevel modelling to investigate putative relationships between salivary testosterone and facial masculinity preferences in a sample of 68 women, while controlling for their age, partnership status, and sociosexuality. We found no significant associations between masculinity preferences and either individual differences or within-woman changes in testosterone...

Background During pubertal development in healthy boys, increased levels of different sex steroids occur which are responsible for sexual maturation and physical changes. However, relationships between various sex hormones and pubertal development stages have not been sufficiently studied. Methods The investigation included 165 normal boys (mean age 12.7±2.8 years, mean body mass index [BMI] 19.6±4.2 kg/m2). Pubic hair (PH) stages were stratified by Tanner and testicular volume (TV) by means of the Prader orchidometer and assigned to the prepubertal, pubertal and postpubertal development phase...

Laboratory experiments revealed the stress hormone cortisol to decrease memory retrieval of emotional material, but a translation to real-life settings is missing so far. In this study, 51 students encoded a list of neutral, positive, and negative words as well as two neutral, biographical notes one day before attendance at a seminar at the university. In the stress condition, students gave a graded oral presentation, whereas they just attended the same seminar in the control condition immediately before retrieval took place...

Individual differences in the response of the stress system to hormonal changes during pregnancy and the postpartum period render some women susceptible to developing depression. The present study sought to investigate peripartum depression and stress hormones in relation to stress-related genotypes. The Edinburgh Postnatal Depression Scale was used to assess peripartum depressive symptoms in a sample of 1629 women, followed from pregnancy week seventeen to six months postpartum. Genotypes of ninety-four haplotype-tag single nucleotide polymorphisms (SNPs) in sixteen genes of the hypothalamus-pituitary-adrenal axis pathway were analyzed and data on psychosocial and demographic factors was collected...

AIM: Salivary duct carcinoma (SDC), an aggressive subtype of salivary gland cancer, is androgen receptor (AR)-positive in 67-96% of cases. In patients with locally recurrent and metastatic (R/M) AR-positive SDC, androgen deprivation therapy (ADT) has an overall response rate of 18-64.7%. In this study, we describe the efficacy of adjuvant ADT in patients with poor-risk (stage 4a) AR-positive SDC. METHODS: This is a retrospective cohort study in which patients with stage 4a AR-positive SDC were offered adjuvant ADT, i...

A 29-year-old G4A3 woman presented at 25 weeks of pregnancy with progressive signs of Cushing's syndrome (CS), gestational diabetes requiring insulin and hypertension. A 3.4 × 3.3 cm right adrenal adenoma was identified during abdominal ultrasound imaging for nephrolithiasis. Investigation revealed elevated levels of plasma cortisol, 24 h urinary free cortisol (UFC) and late-night salivary cortisol (LNSC). Serum ACTH levels were not fully suppressed (4 and 5 pmol/L (N: 2-11)). One month post-partum, CS regressed, 24-h UFC had normalised while ACTH levels were now less than 2 pmol/L; however, dexamethasone failed to suppress cortisol levels...

PURPOSE: The aim of this study was to test the effects of chair-based exercise programs on salivary stress hormones, physical fitness, and functional autonomy of institutionalized older women. METHOD: In total, 47 participants (80 ± 8.04 years old) were recruited and allocated into three groups: chair-based aerobic exercises (CAE, n = 19), chair-based elastic-band strength exercises (CSE, n = 15), and a control group (CG, n = 13). A 14-week exercise intervention was done for the CAE and CSE groups, two times per week, in no consecutive days...

BACKGROUND: Sex differences in cannabis use disorder (CUD) and its treatment have been identified. Women report more severe withdrawal and have shown worse treatment outcomes. Ovarian hormones are implicated in these differences and research suggests that exogenous progesterone may be an effective pharmacotherapy. METHODS: The current randomized, placebo-controlled, feasibility trial tested a novel multimodal methodology for administering exogenous progesterone during acute cannabis withdrawal...

The existence of seasonal changes in secretion of stress hormones and inflammatory mediators by humans is not certain. Here, we aimed to determine whether concentrations of cortisol and interleukin-6 (IL-6) display daily and seasonal rhythmicity. The study was performed in Poznan, Poland (52°N, 16°E) in 7 healthy female volunteers (aged 22.6 ± 0.8 years). Samples of whole mixed unstimulated saliva were collected in winter (February) and summer (June) at 2-hour intervals over a 24-hour period, and analysed for cortisol and IL-6 by immunoassays...

Rock climbing is a physical activity that not only causes an increase in muscle tension, heart rate and blood pressure, but also results in the elevation of stress hormones including cortisol. It has not been established which of the above mentioned variables serve as the most accurate indicator of rock climbing-induced physical and mental stress. The aim of this study was to evaluate the effect of physical activity, short-term fatigue and mental demand on heart rate (HR), salivary cortisol (C) and blood plasma lactate (LA) concentrations in rock climbers under laboratory conditions...

Background: The glycaemic index or load (GI or GL) is a concept for ranking carbohydrate-rich foods based on the postprandial blood glucose response compared with a reference food (glucose). Due to the limited research investigating the effect of the GI or GL of the diet on salivary steroidal hormones, this explorative short study was conducted. Methods: 12 female participants consumed a low GI and a high GI diet for three days each, followed by a washout period between each intervention. Saliva was collected at baseline, and following the low or high GI diets...

BACKGROUND: Consistent with the dual-hormone hypothesis, the combination of high testosterone levels and low cortisol levels has been linked to increased dominant and aggressive behaviors. However, recent research indicates that this association is weaker or even reversed following provocation. It is also unclear whether the association between testosterone/cortisol and aggression is similar for men and women and for those with and without attention-deficit/hyperactivity disorder (ADHD)...

Atopic dermatitis (AD) is a frequent dermatosis with a growing incidence and multifactorial and complex pathogenic mechanisms that are still being investigated. Although the connection between AD and psychological stress has been known for a long time, there is a lack of reliable and objective indicators for the characterization of this association. Psychological stress triggers complex immune pathways. Therefore, acute stress quickly triggers a high release of cortisol and adrenalin or noradrenalin which then stimulates the immune system, primarily T-helper type 1 (Th1 cells) to produce pro-inflammatory cytokines, resulting in a cellular immune response and inflammation...

BACKGROUND AND AIMS: Despite increases in female gambling, little research investigates female-specific factors affecting gambling behavior (GB). Although research suggests that some addictive behaviors may fluctuate across menstrual cycle phase (MCP), gambling requires further investigation. In two studies, we examined associations between MCP and three risky GBs: time spent gambling, money spent gambling, and the probability of consuming alcohol while gambling. Associations between MCP and negative affect were also examined in Study 2...

Ample experimental and associative studies have shown that carrying two short (S) alleles of the serotonin transporter gene (5-HTTLPR) contributes to an increased vulnerability for stress and related affective disorders. Recent findings indicate that this relationship might become even more profound when also possessing a negative ruminative (stress-related) thinking style. However, previous studies on the relationship among 5-HTTLPR, stress, and stress-responsiveness almost exclusively measured salivary cortisol concentrations during exposure to a single acute (laboratory) stressor...

Background: Familial partial lipodystrophy (FPL) is a rare genetic disease characterized by body fat abnormalities that lead to insulin resistance (IR). Clinical conditions linked to milder IR, such as type 2 diabetes (T2D) and metabolic syndrome, are associated with abnormalities of the hypothalamic-pituitary-adrenal (HPA) axis, but little is known about its activity in FPL. Methods: Patients meeting the clinical criteria for FPL were subjected to anthropometric, biochemical and hormone analyses...
