#1
Jon E Grant, Samuel R Chamberlain
Trichotillomania is several times more common in women and has peak onset around puberty. The role of sex hormones, however, has received little research. 11 adolescent girls with trichotillomania, post-menarche and not taking birth control, were examined on a variety of clinical measures. Participants provided saliva samples for analysis of estradiol, progesterone, and testosterone levels. Lower progesterone was associated with more severe symptoms and lower levels of all hormones were associated with worse overall functioning...

BACKGROUND: Diagnostic value of whole saliva may be compromised when blood contamination is present in saliva samples. Measuring transferrin level in saliva samples has been used for detecting the level of blood contamination in saliva. The aim of this study was to investigate the validity of transferrin as a proper biomarker for blood contamination in whole saliva. METHODS: Thirty younger (mean age: 25.9 ± 2.1 years) and twenty older (mean age: 65.1 ± 9...

Saliva as a diagnostic tool is patient friendly and offers analytical advantages. Hormonal analysis of saliva is not influenced by changes in concentrations of binding globulins as the free concentration of the hormones is measured. Analysis of salivary cortisol is common practice in the diagnostic work-up of hypercortisolism. We investigated the potential role of measuring salivary cortisol when adrenal insufficiency (AI) is suspected, to reduce the numbers of ACTH stimulation tests. Over a period of 6 years, patients undergoing an ACTH stimulation test (tetracosactide, 250 µg) in our hospital were included...

Previous investigations have explored stress and pubertal hormones in parallel; it has been a recent development, however, to explore the relationships between different hormones during puberty, and how this hormonal cross-talk may be influenced by the environment. The current study investigated neuroendocrine coupling, or the extent to which hormones are correlated within the individual, and also investigated early life stressors that may influence coupling. Participants were 405 adrenarcheal children (mean Tanner stage=1...

The biochemical ageing status of women in the menopausal transition was studied using quantitative analysis of age- and autophagy-related gene activities (CDC42 and MAP1LC3 genes were selected as target genes). Free estradiol and progesterone levels in saliva were estimated. General linear models were used to determine the relationship between lifestyle, health status, socioeconomic factors and CDC42 and MAP1LC3 gene expression levels. Gene expression analysis revealed (1) an increasing expression of CDC42 gene after 45years in women, (2) expression level of CDC42 gene associated with menopausal status, (3) while endocrine status was found to associate with the expression of both of the studied age-related genes, (4) the "never used hormonal contraceptives" and "obese nutritional status" were the strongest factors for increased level of age-related gene expressions, and (5) changes in gene expression levels by ageing should be studied by considering not only chronological, but also biological ages...

Cortisol is an important stress hormone affected by a variety of biological and environmental factors, such as the circadian rhythm, exercise and psychological stress. Cortisol is mostly measured using blood or saliva samples. A number of genetic variants have been found to contribute to cortisol levels with these methods. While the effects of several specific single genetic variants is known, the joint genome-wide contribution to cortisol levels is unclear. Our aim was to estimate the amount of cortisol variance explained by common single nucleotide polymorphisms, i...

Testosterone is the principal endogenous androgenic-anabolic steroid in humans. The levels of testosterone in the human body are correlated with many hormonal disorders (hypogonadism, impotence, etc) mostly in men, and with many types of diseases such as: prostate cancer, metabolic syndrome, obesity, cardiovascular diseases and so on. Testosterone is extensively used among sportsmen willing to increase strength, aggressiveness, and recovery; making it the most commonly reported substance in steroid abuse. Fast, easy and cheap methods for the evaluation of testosterone are extremely needed in clinics and hospitals...

Purpose: Oxytocin and arginine vasopressin are associated with different aspects of the stress response. As stress is regarded as a risk factor for vocal symptoms, we wanted to explore the association between the oxytocin receptor gene (OXTR) and arginine vasopressin 1A receptor gene (AVPR1A) single-nucleotide polymorphisms (SNPs) and vocal symptoms. We also wanted to explore whether such effects might be mediated by cortisol because oxytocin and vasopressin are associated with cortisol levels...

Violence has a negative impact on adolescents and affects their quality of life. It causes stress and requires the victim's adaptive capacity, which can cause psychological and biological changes. Hormone cortisol levels have been used as stress biomarker in several studies. This paper aims to perform a systematic literature review of publications on cortisol and violence involving teenagers from 2000 to 2013. Descriptors "cortisol", "violence" and "adolescent" were used in both English and Portuguese in this review, which included bibliographic databases PubMed/Medline, Lilacs, BVS and SciELO...

Human saliva is a potential diagnostic fluid and any alteration in body might be reflected in saliva so that saliva is considered as "mirror of the body". Variations in salivary hormone level, ultra structure, pH, flow rate, buffering capacity and electrolytes level are found during menstrual cycle in regard to ovulation. Thirty healthy volunteers were used for the assessment of physico-chemical changes in saliva. Reproductive cycle was categorized as pre-ovulation phase (5 to 12 days), ovulation phase (13 or 14 days) and post-ovulation phase (15 to 25 days) according to salivary arborization test and hormonal analysis...
