research Cheating on forensic hair testing? Detection of potential biomarkers for cosmetically altered hair samples using untargeted hair metabolomics
Researchers found markers that can tell if hair has been bleached, which could improve hair test accuracy.
research Towards Best Practice in Hair Metabolomic Studies: Systematic Investigation on the Impact of Hair Length and Color
Hair color and length affect metabolite profiles in hair, so they should be considered in hair analysis.
research Toward Elucidating Epigenetic and Metabolic Regulation of Stem Cell Lineage Plasticity in Skin Aging
Epigenetic and metabolic changes affect stem cell function and aging in skin.
research Metabolomic and lipidomic atlas of human hair across its length
Human hair contains many different molecules that change along its length, influenced by personal care products.
research Associations between ionomic profile and metabolic abnormalities in a murine model of sodium sulfide induced alopecia areata
Targeting gut microbiome and metabolome may help treat autoimmune skin diseases like alopecia areata.
research Metabolism of Minoxidil, a New Hypotensive Agent 11: Biotransformation following Oral Administration to Rats, Dogs, and Monkeys
Minoxidil metabolizes similarly in monkeys and humans, but differently in dogs and rats.
research Different localizations of drugs simultaneously administered in a strand of hair by micro‐segmental analysis
Drugs localize differently in hair strands based on their properties.
research Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry
The study found that urine metabolites M1b or M4 are the best indicators of ATD use in horses, with detection possible up to 77 hours in urine and 28 hours in blood.
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 External post mortem artefact: a key issue in hair result interpretation
Hair test results can be misleading due to contamination, so they shouldn't be used alone to determine drug use.
research Separation of finasteride and analogues
Finasteride and analogues separated using LC-MS-MS technique.
research Enzyme-linked immunosorbent assays for doping control of 5α-reductase inhibitors finasteride and dutasteride
New tests detect finasteride and dutasteride in urine quickly and easily.
research Molecular docking simulation studies on potent butyrylcholinesterase inhibitors obtained from microbial transformation of dihydrotestosterone
Metabolite 7 is a strong inhibitor for Alzheimer's disease management.
research Developmental Toxicity of Levo-Alpha-Acetylmethadol (LAAM) in Tolerant Rats
LAAM caused developmental toxicity in tolerant rats without causing birth defects.
research 5α‐reductase inhibitors: Evaluation of their potential confounding effect on GC‐C‐IRMS doping analysis
5α-reductase inhibitors can interfere with doping tests by masking banned substances.
research Application of multi-omics techniques to androgenetic alopecia: Current status and perspectives
Multi-omics techniques help understand the molecular causes of androgenetic alopecia.
research Original article / Article original External post mortem artefact: a key issue in hair result interpretation
Hair test results can be misleading due to external contamination, so they shouldn't be used alone to assess long-term drug use.
research Metabolite identification by mass spectrometry of the 5α-reductase inhibitor finasteride in vitro and in vivo
Finasteride's metabolites were identified, helping understand how the drug is processed in the body.
research Rare and common genetic determinants of metabolic individuality and their effects on human health
Genetic variations greatly affect individual metabolism and can impact health and disease risk.
research Intracrine androgen biosynthesis, metabolism and action revisited
The document concludes that blocking the internal pathways that create androgens might help treat cancers that depend on sex hormones.
research Circulating androgen regulation by androgen-catabolizing gut bacteria in male mouse gut
Gut bacteria can lower androgen levels in male mice.
research Recent omics advances in hair aging biology and hair biomarkers analysis
More research is needed to understand hair aging and develop effective treatments.
research 520 Body site heterogeneity and microbial diversity is lost in individuals with hidradenitis suppurativa
People with Hidradenitis Suppurativa have less diverse skin bacteria and different bacterial metabolism than healthy individuals.
research Causal Relationship Between Blood Metabolomics and Female Pattern Hair Loss: A Bidirectional Mendelian Randomization Study
Certain blood metabolites are linked to female pattern hair loss, with some increasing risk and others offering protection.
research Untargeted metabolomics and steroid signatures in urine of male pattern baldness patients after finasteride treatment for a year
Finasteride treatment changes urine metabolites in male pattern baldness patients.
research Cutaneous Androgen Metabolism: Basic Research and Clinical Perspectives
Creating stronger blockers for skin enzymes might lead to better treatment for conditions like acne and excessive hair growth.
research Clinical and Biochemical Parameters of Androgen Action in Normal Healthy CaucasianVersusChinese Subjects
Caucasian men have more chest hair and higher levels of certain androgen products than Chinese men.
research Assessment of Circulating Sex Steroid Levels in Prepubertal and Pubertal Boys and Girls by a Novel Ultrasensitive Gas Chromatography-Tandem Mass Spectrometry Method
Prepubertal girls have higher sex steroid levels than boys, possibly leading to earlier puberty.
research The Distribution of Estrogen Receptor β Is Distinct to That of Estrogen Receptor α and the Androgen Receptor in Human Skin and the Pilosebaceous Unit
Estrogen Receptor ß (ERß) is the main hormone controller in human skin and hair follicles, not Estrogen Receptor α (ERα) or the Androgen Receptor (AR).
