research Distribution of bacterial community structures on human scalp hair shaft in relation to scalp sites
Bacterial communities on scalp hair are unique to each person but consistent across different scalp sites.
research SUN-195 Falsely Elevated Testosterone Levels: Role of LC-MS/MS in Reducing Unnecessary Testing
Using LC-MS/MS for hormone measurement can prevent false high testosterone results and avoid unnecessary tests.
research Measurement and comparison of various androgen levels in women with severe acne, hirsutism, and androgenic alopecia
Women with severe acne, hirsutism, and androgenic alopecia often have higher levels of certain androgens, but the specific pattern can't be predicted just by looking at symptoms.
research Digit ratio 2D:4D is a possible indicator for androgenetic alopecia in males
Finger length ratio may indicate male hair loss.
research Steroidomics for highlighting novel serum biomarkers of testosterone doping
Monitoring steroid hormones in blood can better detect testosterone doping.
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 Evaluation of the serum C‐reactive protein–albumin ratio and its relationship with disease severity IN alopecia areata: A prospective case–control study
CAR is a useful marker for assessing alopecia areata severity.
research Sex steroid levels in corresponding cerebrospinal fluid and serum samples quantified by mass spectrometry in men
DHEA is the main sex steroid in cerebrospinal fluid, and testosterone in the fluid comes from the blood.
research Human gene correlation analysis (HGCA): A tool for the identification of transcriptionally co-expressed genes
The HGCA tool helps identify genes that work together by analyzing their co-expression patterns.
research 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 LC‐MS/MS‐based method for long‐term steroid profiling in human scalp hair
A new method accurately measures long-term steroid levels in human hair.
research Binding of Steroid Hormones by the 105,000 x g Supernatant Fraction from Homogenates of Rat Skin and Variations during the Hair Cycle
Steroid hormone binding in rat skin varies with pH, heat, and hair cycle phases.
research Forensic skeletal and molecular anthropology face to face: Combining expertise for identification of human remains
Combining skeletal and molecular anthropology improves identifying human remains.
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 Does myo-inositol oxygenase, the only enzyme to catalyze myo-inositol in vivo, play a role in the etiology of polycystic ovarian syndrome?
The enzyme myo-inositol oxygenase is not linked to the cause of polycystic ovarian syndrome.
research Integrative analysis of Iso-Seq and RNA-seq data reveals transcriptome complexity and differential isoform in skin tissues of different hair length Yak
Different genes affect hair length in yaks.
research Determination Method for Steroid 5α-Reductase Activity Using Liquid Chromatography/Atmospheric Pressure Chemical Ionization–Mass Spectrometry
A new method was developed to measure and assess the activity and inhibition of the enzyme steroid 5α-reductase.
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 hormone changes similar to humans, but also have key differences.
research Trace Elements in Human Hair : III) Variation in the Contents of Iron, Copper and Zinc by Age and Sex.
Women generally have higher levels of iron, copper, and zinc in their hair than men, with differences increasing with age.
research Weak correlations between serum and cerebrospinal fluid levels of estradiol, progesterone and testosterone in males
Blood hormone levels don't accurately show brain hormone levels in males.
research Spectral-Analysis As A Diagnostic Tool For Birds
Spectral-analysis can help diagnose mineral imbalances in birds.
research Rapid high-performance liquid chromatogaphic method for detection of interindividual differences in carcinogen metabolism
Human hair follicles can assess carcinogen metabolism and imidazole compounds might be effective anticarcinogens.
research Effects of Heavy Ions on Rabbit Tissues: Damage to the Forebrain
Heavy ions cause significant damage to rabbit forebrains, similar to other radiation effects.
research Evaluation of ovarian reserve and function in female patients treated with oral isotretinoin for severe acne: an exploratory study
Oral isotretinoin for severe acne can change hormone levels but does not significantly affect ovarian function.
research In-vivo uptake and metabolism of testosterone by the skin and other tissues of the rat
Rat skin takes up and processes testosterone differently than other organs, with testosterone being more important for the skin than its metabolite 5α-DHT.
