810-840 / 1000+ resultsresearch Profiling steroid and thyroid hormones with hair analysis in a cohort of women aged 25 to 45 years old
The method can measure multiple hormones in women's hair and may help identify hormone-related health issues.
research Serum and hair steroid profiles and their associations with body composition in adolescence
Hair steroid profiling is a feasible, non-invasive alternative to serum analysis for assessing hormone levels and metabolism.
research Immunohistochemical analysis of estrogen and progesterone receptors in endometrium and peritoneal endometriosis: A new quantitative method
The new method showed that endometriotic tissue has lower estrogen receptor levels but similar progesterone levels compared to normal endometrium, with both following a similar cycle.
research Serum and hair steroid profiles and their associations with body composition in adolescence.
Androgen levels are more linked to body size in boys than girls.
research New frontiers in human hair follicle (neuro‐)endocrinology
Human scalp hair follicles can produce and respond to several hormones, affecting hair growth and pigmentation.
research Sex differences in steroid levels and steroidogenesis in the nervous system: Physiopathological role
Men and women have different levels and production of brain steroids, which may affect their risk for certain brain disorders.
research Neuroendocrinology of the hair follicle: principles and clinical perspectives
Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.
research Sexually dimorphic effect of progesterone and its reduced metabolites on the gene expression of myelin proteins in rat Schwann cells
Progesterone and its metabolites affect myelin protein expression differently in male and female rat Schwann cells.
research Divergent neuroactive steroid responses to stress and ethanol in rat and mouse strains: relevance for human studies
Different rat and mouse strains respond differently to stress and alcohol, which may help us understand similar human mechanisms.
research Clinical Impact of Molecular Diagnostics in Endocrinology
Molecular diagnostics help identify genetic defects causing endocrine diseases, improving diagnosis and treatment options.
research Determination of steroid hormones in human hair as a retrospective biomarker with HPLC-MS/MS
A new method accurately measures long-term hormone levels in hair.
research Urinary steroid metabolome shows adrenal, gonadal, and neuroactive steroid dysregulation in adolescents with depression
Depressed teens have different steroid levels in urine, which may help identify and treat them.
research Liquid Chromatography-Mass Spectrometry-Based In Vitro Metabolic Profiling Reveals Altered Enzyme Expressions in Eicosanoid Metabolism
The method reliably profiles eicosanoids and shows epitestosterone reduces their levels, similar to common anti-inflammatory drugs.
research Sex Hormones and their Analogues in Neuroimmune Biology
Sex hormones influence immune responses and may help treat diseases.
research Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
The methods accurately measured brain androgens, showing most 5α-androstane-3α,17β-diol comes from outside the brain, while androsterone is both transported and made in the brain.
research Hair trace elementary profiles in aging rodents and primates: links to altered cell homeodynamics and disease
research Abstract 4993: A longitudinal examination of nutritional-inflammatory biomarker associations with cancer related cognition, treatment side effects and quality of life in newly diagnosed older adults undergoing chemotherapy
Certain blood markers can help predict and manage chemotherapy side effects in older cancer patients.
research OR20-01 Machine Learning-based Steroid Metabolome Analysis In Women With Polycystic Ovary Syndrome Reveals Three Distinct Androgen Excess Subtypes With Different Metabolic Risk Profiles.
Machine learning identified three unique subtypes of androgen excess in women with PCOS, each with different metabolic risks.
research Altered Hormone and Bioactive Lipid Plasma Profile in Rodent Models of Polycystic Ovarian Syndrome Revealed by Targeted Mass Spectrometry
Rodent models of PCOS show some similar and some different lipid changes compared to humans.
research Screening for 21-hydroxylase–deficient nonclassic adrenal hyperplasia among hyperandrogenic women: a prospective study
Testing basal 17-HP levels is a good way to screen for nonclassic adrenal hyperplasia in women with high androgen levels.
research Significant Effects of Mild Endogenous Hormonal Changes in Humans: Considerations for Low-Dose Testing
Small hormonal imbalances can cause significant health problems, so more sensitive testing for hormone-disrupting chemicals is needed.
research Expression patterns of the glial cell line–derived neurotrophic factor, neurturin, their cognate receptors GFRα-1, GFRα-2, and a common signal transduction element c-Ret in the human skin hair follicles
Certain proteins and their receptors are more active during the growth phase of human hair and could be targeted to treat hair disorders.
research 837 Characterization of cutaneous hormone production through analysis of skin secretions
Skin produces different hormones depending on body part and sex, and a new method can measure them.
research Neuroactive steroid levels and psychiatric and andrological features in post-finasteride patients
Post-finasteride patients show changed neuroactive steroid levels, possibly causing erectile dysfunction and depression.
research Differential Expression of miR-93 and miR-21 in Granulosa Cells and Follicular Fluid of Polycystic Ovary Syndrome Associating with Different Phenotypes
The study found that certain microRNAs are higher in the cells and lower in the fluid of women with a specific type of polycystic ovary syndrome, and one microRNA could potentially help diagnose the condition.
research 17-Hydroxyprogesterone Responses to Gonadotropin-Releasing Hormone Disclose Distinct Phenotypes of Functional Ovarian Hyperandrogenism and Polycystic Ovary Syndrome
The research found that polycystic ovary syndrome (PCOS) has two distinct types, with one having more severe hormone and insulin issues.
research Demonstrating the potential of untargeted hair proteomics for personalized biomarkers in stress-associated disorders
Hair proteomics could be a promising non-invasive way to identify stress-related disorders.
