research Preparation of3H-labelled testosterone metabolites
The conclusion is that tritium-labeled testosterone metabolites can be made and are better converted into dihydrotestosterone in skin cells than in prostate tissue.
research Total testosterone to dihydrotestosterone ratio assessed by LC-MS/MS predicts a worse metabolic profile not only in PCOS patients
A higher testosterone to dihydrotestosterone ratio may indicate worse metabolic health in women.
research Simultaneous quantitation of nine hydroxy-androgens and their conjugates in human serum by stable isotope dilution liquid chromatography electrospray ionization tandem mass spectrometry
A new method accurately measures nine specific hormones in human blood.
research Direct quantitative digital autoradiography of testosterone metabolites in the pilosebaceous unit: an environmentally advantageous trace radioactive technology
The method accurately measures testosterone metabolites with high sensitivity and low environmental impact.
research Characterisation of low abundance wool proteins through novel differential extraction techniques
New techniques helped identify rare wool proteins by reducing dominant ones.

research Cyproterone Acetate Quantification in Human Plasma by High-performance Liquid Chromatography Coupled to Atmospheric Pressure Photoionization Tandem Mass Spectrometry
The method accurately measures cyproterone acetate in plasma, showing no significant difference between two formulations.
research Sex hormone-binding globulin (SHBG) and androgen levels in women with androgenetic alopecia
The T/SHBG ratio may be a useful marker for androgen activity in women with androgenetic alopecia.
research Single hair analysis by X-ray fluorescence spectrometry detects small changes in dietary zinc intake: A nested randomized controlled trial
Hair analysis can detect small changes in dietary zinc intake.
research Association between the serum estrone-to-estradiol ratio and parameters related to glucose metabolism and insulin resistance in women with polycystic ovary syndrome
Higher estrone-to-estradiol ratios are linked to worse glucose metabolism and insulin resistance in women with PCOS.
research Matrix effects and application of matrix effect factor
Matrix effects in LC-MS can be managed but not completely avoided.
research Distributions of sulphur and other elements in human hair follicles
Sulphur in hair follicles increases from the bulb and then levels off, while other elements vary in distribution.
research Setting reference values in trichology
Normal hair density and diameter ratios were established to help diagnose adult hair loss.
research Element profiles of mouse hair: A concern for using hair as a timetable repository
Mouse hair element patterns vary, making it unreliable for tracking time.
research Assessment of the Mean Platelet Volume-to-Platelet Count Ratio in Alopecia Areata: A Retrospective Case Control Study
The MPV/PC ratio can help assess disease activity in alopecia areata.
research An isolated, implausibly large effect in a case-control study of digit ratio (2D:4D) and male androgenetic alopecia: Comment on Unal (J Cosmet Dermatol 2018;17(3):545-548)
Digit ratio likely doesn't predict male hair loss.
research Reproductive profiles, androgen hormones and energetic status of oligomenorrheic exercising women
Exercising women with irregular periods have lower thyroid hormone levels and less body fat.
research Topological Markers for Subcellular Chemical Mapping using TOF-SIMS
TOF-SIMS improved chemical mapping in cells, confirming gunshot residue, tracking anti-tumor drugs, and identifying molecules in mosquitoes and wounds.
research HIGH DEVELOPMENTAL AGE AND POOR HAIR MULTI-ELEMENT PROFILE IN A 3.75-YEAR-OLD GIRL − DIFFERENTIAL RATES IN SHAPING OF BODY ORGAN GROWTH
A 3.75-year-old girl showed that different body organs can grow at different rates.
research Digit-length ratios (2D:4D) as a phenotypic indicator of in utero androgen exposure is not prognostic for androgenic alopecia: a descriptive-analytic study of 1200 Iranian men
Finger length ratios don't predict baldness in men.

research Sequential Hair Shaft as an Indicator of Prior Mineralization in the Alaskan Moose2
Moose hair can track past mineral levels, except zinc.
research Tritiated Thymidine: Effect of Decomposition by Self-Radiolysis on Specificity as a Tracer for DNA Synthesis
Decomposed tritiated thymidine is less accurate for DNA tracing, and hair changes can indicate malnutrition.
