research Isotope Dilution-Based Targeted and Nontargeted Carbonyl Neurosteroid/Steroid Profiling
Researchers created a new method to measure brain steroids, finding higher levels of certain steroids and changes due to a drug.
research Matrix matching in quantitative bioanalysis by LC–MS/MS a dream or a reality?
Accurate quantitative bioanalysis using LC-MS/MS is challenging due to matrix effects, but using internal standards and new methods like in-sample calibration could improve results.
research Monitoring spatially resolved trace elements in polar bear hair using single spot laser ablation ICP-MS
Laser ablation ICP-MS is effective for tracking trace elements in polar bear hair over time.
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.
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 Hair radioactivity as a measure of exposure to radioisotopes

The study developed a method to analyze ancient hair proteins using very small samples.
research Two-dimensional electrophoretic analysis of human hair keratins, especially hair matrix proteins
The method effectively analyzes human hair proteins, especially nonfilamentous ones.
research Determination of As by instrumental neutron activation analysis in sectioned hair samples for forensic purposes: chronic or acute poisoning?
The woman likely died from acute arsenic poisoning, not chronic exposure.
research Matrix effects and application of matrix effect factor
Matrix effects in LC-MS can be managed but not completely avoided.
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 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 Characterisation of low abundance wool proteins through novel differential extraction techniques
New techniques helped identify rare wool proteins by reducing dominant ones.
research Investigation of human hair using ToF-SIMS: From structural analysis to the identification of cosmetic residues
The conclusion is that a new method can identify cosmetic residues on hair and match them to their products.
research Segmental hair analysis - a retrospective testosterone diary?
Hair analysis can somewhat track past testosterone levels but is influenced by factors like hair washing, growth rate, sex, and hair color.
research The use of electron spin resonance techniques to determine gamma ray exposure of $\alpha$-keratin in human hair
Whole hair strands can reliably measure gamma ray exposure using ESR techniques, but samples should be analyzed quickly or stored in liquid nitrogen.
research Incorporation of Isotopically Labeled Cocaine and Metabolites into Human Hair: 1. Dose-Response Relationships
Hair analysis can detect cocaine use but doesn't accurately show the amount or timing of use.
research Detection of Iodine by Scanning Electron Microscopy(SEM) and Energy Dispersive Spectroscopy(EDS) Following Contact with an Iodine Releasing Coating
The method successfully visualizes iodine in biological tissues.
research Generalized pruritus in primary sclerosing cholangitis: implications of histamine release by lysophosphatidic acid
