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 The feasibility of quantitative analysis of androgen metabolism by use of single dermal papillae from human hair follicles
Using single dermal papillae is unreliable for analyzing androgen metabolism in hair follicles.
research Presence of iron in segmented heterochromia of the scalp hair without iron-deficiency anaemia
Iron can be present in hair color changes without overall iron deficiency.
research Conformational differences in protein disulfide linkages between normal hair and hair from subjects with trichothiodystrophy: A quantitative analysis by Raman microspectroscopy
TTD hair is brittle due to fewer sulfur amino acids and unstable disulfide bonds.
research In search of decoding the syntax of the bioelements in human hair – A critical overview
Hair analysis can show nutritional status and environmental exposure, with phosphorus being very stable in hair and differences found based on gender and conditions like depression and autism.
research Proton Affinitive Derivatization for Highly Sensitive Determination of Testosterone and Dihydrotestosterone in Saliva Samples by LC-ESI-MS/MS
Using 5-butylpicolinate esters improves the sensitivity and reliability of detecting testosterone and dihydrotestosterone in saliva.
research Isolation and Characterization of Mouse High-glycine/Tyrosine Proteins
Mouse high-glycine/tyrosine proteins have distinct patterns in hair follicles, peaking at specific hair cycle days.
research Exogen hair characterization in human scalp
The conclusion is that exogen is a unique hair cycle phase and the new sampling method specifically targets this stage, which may help in future hair loss research.
research Intermolecular NH 2 -/Carboxyl-terminal Interactions in Androgen Receptor Dimerization Revealed by Mutations That Cause Androgen Insensitivity
Mutations at Val-889 and Arg-752 disrupt key interactions in androgen receptor dimerization.
research Steroid 17β-hydroxysteroid dehydrogenase deficiency in man: An inherited form of male pseudohermaphroditism
Affected males are born with ambiguous genitalia, raised as females, but develop male traits at puberty due to enzyme deficiency.
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 Determination of traces of silver in human scalp hair slurries by electrothermal atomic absorption spectrometry
research Segmental Hair Analysis for 11-Nor- 9-Tetrahydrocannabinol-9-Carboxylic Acid and the Patterns of Cannabis Use
THCCOOH levels in hair decrease from root to tip and don't match well with self-reported cannabis use.
research CRYSTAL STRUCTURE OF HSIANGHUALITE
research Carbon quantum dots applied to the chemical sensing of cobalt ions and methylcobalamin
Carbon Quantum Dots can effectively detect cobalt ions and methylcobalamin in water.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research Radiolabel validation of cortisol in the hair of rhesus monkeys
Hair cortisol can indicate long-term stress levels, but hair growth rate differences may affect accuracy.
research A New Case of Isolated Trichothiodystrophy
A rare case of isolated trichothiodystrophy was identified, marked by brittle hair with low sulfur content.
research Biochemical Insights and Clinical Applications of Ischemia-Modified Albumin in Ischemic Conditions
Ischemia-modified albumin can help diagnose ischemic conditions early, but better detection methods are needed.
research Electrophoretic analysis of human hair keratins
Family members have similar hair protein patterns, which could be useful for genetic studies.
research Phenomenology of polymorphism: The topological pressure–temperature phase relationships of the dimorphism of finasteride
Finasteride's two forms have different stability based on temperature and pressure.
research Uptake of sulfur-35 in human hair.
Sulfur-35 can be used to track hair growth and past exposure.
research Natural variability and the influence of concurrent control values on the detection and interpretation of low-dose or weak endocrine toxicities.
Control variability makes it hard to confirm low-dose endocrine effects.
research Transcriptomic regulation of seasonal coat color change in hares
Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.
research Trichohyalin, an intermediate filament-associated protein of the hair follicle.
Trichohyalin is a protein in hair follicles that helps form hair filaments.
research Segmental analysis of human hair reveals intra-annual variation in 25(OH)D3 concentrations in modern and archaeological individuals
Hair analysis can show changes in vitamin D levels over time.
