research Bone mineral density in hyperandrogenic amenorrhoea
Women with hyperandrogenic amenorrhea have similar bone density to healthy women but lower than androgenized women without amenorrhea, and high DHEAS levels might affect bone density.
research The differences between aromatizable and non-aromatizable androgens in relation to body composition and metabolic syndrome risk factors in men
Testosterone and dihydrotestosterone have similar effects on body composition and metabolic health in men.
research Hair Tissue Mineral Analysis and Metabolic Syndrome
research New fluorogenic probes for neutral and alkaline ceramidases
New probes were created to effectively measure specific enzymes involved in fat metabolism, which could help develop new drugs.
research Evaluation of neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, mean platelet volume, CRP and ESR with disease severity in patients with alopecia areata
Higher MPV and CRP levels may indicate more severe alopecia areata.
research Metal doped keratin film standard for LA-ICP-MS determination of lead in hair samples
A new method accurately measures lead levels in hair to assess exposure.
research Utility of fur as a biomarker for persistent organic pollutants in Australian fur seals (Arctocephalus pusillus doriferus)
Australian fur seals' fur shows high levels of pollutants, which may be linked to hair loss in young female seals.
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 Optimization of LC method for the determination of testosterone and epitestosterone in urine samples in view of biomedical studies and anti-doping research studies
Researchers developed a reliable method to measure testosterone and epitestosterone in urine for medical and anti-doping use.
research Metabolomics analysis reveals metabolite diversity of the rare cliff plant Oresitrophe rupifraga Bunge
The rare cliff plant Oresitrophe rupifraga has diverse metabolites, with leaves rich in phenolic acids and rhizomes and bulblets high in terpenoids, aiding its growth and potential use.
research Short sequence repeats of the intergenic spacer regions of ribosomal RNA genes in Malassezia globosa and M. restricta colonizing the scalps of male individuals with and without androgenetic alopecia
A specific DNA pattern in Malassezia restricta may be linked to hair loss in men.
research Untargeted hair lipidomics: comprehensive evaluation of the hair-specific lipid signature and considerations for retrospective analysis
research Multiplex matrix network analysis of protein complexes in the human TCR signalosome
Alopecia areata patients show unique protein activity patterns, suggesting imbalanced signaling pathways.
research Table S1. Disease-dependent differences between tape-strip and bulk biopsy ssGSEA scores across hair follicle compartments
research Table S1. Disease-dependent differences between tape-strip and bulk biopsy ssGSEA scores across hair follicle compartments
research Structural characterization and bioactive screening of two homogeneity proteins from Tianshan red deer abomasum
Proteins from Tianshan red deer abomasum have strong anti-inflammatory, anti-tumor, and antioxidant effects.
research Determination of estradiol and progesterone concentrations in human scalp hair
Hair levels of estradiol and progesterone are higher in premenopausal than postmenopausal women, but the difference isn't statistically significant, indicating the need for a better measurement method.
research Analysis of sequential hair segments reflects changes in the metabolome across the trimesters of pregnancy
Hair analysis can reveal metabolic changes and potential pregnancy complications.
research The Use of 2D: 4D Digit Ratio as a Predictor of Androgenetic Alopecia: A Review
Finger length ratios might help predict common hair loss.
research Structural characterization of cyclosporin A, C and microbial bio-transformed cyclosporin A analog AM6 using HPLC–ESI–ion trap-mass spectrometry
Researchers developed a method to identify and analyze cyclosporin compounds and their structures effectively.
research P131 Menstrual irregularity in hirsute women
Hirsute women with ovarian-sourced hirsutism are more likely to have irregular periods, with higher BMI and altered hormone ratios.
research Exploring Reference Values for Hair Cortisol
Hair sample weight is a better measure for cortisol levels in hair than hair protein concentration.
research Measuring changes in chemistry, composition, and molecular structure within hair fibers by infrared and Raman spectroscopic imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
research COMPARING THE EFFECTIVENESS OF ORAL ISOTRETINOIN AND CYPROTERONE COMPOUND IN ACNE TREATMENT AMONG ADULT FEMALES WITH CUTANEOUS HYPERANDROGENISM: A PROSPECTIVE STUDY.
Isotretinoin is recommended for acne treatment as it is as effective as cyproterone compound.
research Insulin sensitivity, androgens and isotretinoin therapy in women with severe acne
Isotretinoin improves severe acne without changing androgen or insulin levels but may increase body weight and triglycerides.
research In situ labeling of DNA reveals interindividual variation in nuclear DNA breakdown in hair and may be useful to predict success of forensic genotyping of hair
In situ DNA labeling in hair can help predict forensic DNA analysis success.
research Fidelity of the Human Mitochondrial DNA Polymerase
