research Urinary Androgens Provide Additional Evidence Related to Metabolism and Are Correlated With Serum Androgens in Girls
The research found that measuring androgens in urine can give extra information about body metabolism and is linked to androgen levels in the blood, especially in young girls.
research Inhibition of 3‐methylcrotonyl‐CoA carboxylase explains the increased excretion of 3‐hydroxyisovaleric acid in valproate‐treated patients
Valproic acid treatment increases a specific acid in urine by blocking an enzyme, possibly causing skin rash and hair loss.
research A Review on Forensic Toxicological Analysis of Drugs in Hair using Various Instrumental Techniques
Hair analysis is better than urine and blood for detecting past drug use.
research Long-term detection of methyltestosterone (ab-) use by a yeast transactivation system
A yeast-based test can detect the steroid methyltestosterone in urine longer than traditional methods.
research Evaluation of noninvasive biospecimens for transcriptome studies
Hair follicles and urine cell pellets are promising for transcriptome studies due to consistent quality and useful expression profiles.
research Evaluation of noninvasive biospecimens for transcriptome studies
Hair follicles and urine cell pellets are promising for transcriptome studies.
research Screening and confirmation methods of the major urinary metabolite of finasteride–carboxy-finasteride by liquid chromatography–mass spectrometry and liquid chromatography–tandem mass spectrometry
New methods can detect finasteride's major urinary metabolite in urine for up to 49 hours.
research Testosterone-like immunoreactivity in hair measured in minute sample amounts - a competitive radioimmunoassay with an adequate limit of detection
The new test can measure very small amounts of testosterone in hair, and grinding the hair up first gives more accurate results.
research Measurement of steroid hormones by liquid chromatography-tandem mass spectrometry with small amounts of hair
A new method accurately measures steroid hormones in a few hair strands and could help study chronic stress and hair loss.
