This study presents a novel assay that allows for the simultaneous measurement of various androgens and 5α-reductase inhibitors in male serum, facilitating research into the biochemical effects of these inhibitors.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This study found that women with telogen effluvium had significantly lower serum copper and zinc levels compared to controls, suggesting these deficiencies may be associated with the condition.

This study introduced a new method for extracting red mordant dyes from wool fibers that preserved the fibers for further analysis and allowed for spectrophotometric examination of the dyes' absorption curves.

This study proposed a method to determine residual levels of dichloromethane and chloroform in finasteride using SPME-GC, reporting high linear correlation coefficients for both solvents.

In this case study, authors reported that a 43-year-old female patient initially showed persistently high testosterone levels due to immunoassay interference, later verified as normal using liquid chromatography-tandem mass spectrometry (LC-MS/MS), highlighting the need to consider assay artifacts in diagnosing hyperandrogenism without clinical signs.

This research found that nod factor can induce root hair reorientation and gene expression in Medicago truncatula with as little as a single molecule, implicating heterotrimeric G-protein signaling in this process.

This study explored the potential of using isoenzyme detection after electrophoresis to characterize human hair, though no new clinical results are reported.

This study found that laser ablation-inductively coupled plasma-mass spectrometry can effectively reconstruct time-resolved mercury exposure in micrometer segments of a single hair strand from fish-eaters.

This study identified that the ethanol extract of Selaginella doederleinii may enhance the effectiveness of doxorubicin in treating cervical cancer cells while also providing chemopreventive benefits.

This study found that deferiprone significantly reduced dermal fibrosis and skin thickness in mice with chronic kidney disease treated with Omniscan, suggesting iron's role in gadolinium chelate toxicity and nephrogenic systemic fibrosis.

This review discusses recent progress in PENG-based sensors for non-invasive medical diagnosis and treatment but reports no new experimental results.

In this animal study, exposure to 150 kHz electromagnetic radiation significantly reduced the number and size of follicular cysts in rats with estradiol valerate-induced polycystic ovaries.

This study found that repeatedly collecting hair follicles from individuals with fragile X syndrome is feasible for measuring FMR1 and FMRP levels in both home and office settings.

This study developed a high-throughput method that identifies bioactive chemicals influencing DHT production in prostate cancer cells, with potential nutraceutical candidates including fucoxanthin, phenethyl caffeate, and Curcuma longa L. extract.

This study identified a novel microscopic "arrow sign" in hair root sheaths of patients on EGFR inhibitors, potentially aiding in diagnosing related hair changes and differentiating from fungal infections.

This study synthesized silver nanoparticles using Gandaria stem bark extract, finding that nanoparticles at a 4% concentration were particularly effective for selectively detecting mercury over lead and calcium, making them suitable as preliminary detection materials for mercury in facial whitening creams.

This study found that human hair shafts emit electromagnetic signals that can create images through thin glass barriers, potentially influenced by static electricity.

This study optimized a screening assay to identify molecules that inhibit or enhance TRPM5 ion channel activity, which may have implications for treating dysfunctions linked to cardiac arrhythmias and diabetes.

This study demonstrates a sample preparation method for wool follicles that allows for clear keratin labeling and ultrastructural preservation in microscopy, reducing common artefacts from conventional fixation techniques.

This review discusses the growing use of scalp hair for elemental analysis in various fields and highlights advancements in analysis techniques, including the future potential of laser ablation ICP-MS, but reports no new clinical results.

Hair properties change under electromagnetic fields and are influenced by individual characteristics and the environment.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study describes an efficient gas chromatography-mass spectrometry method for detecting estrone and 17 beta-estradiol concentrations in hair, finding differing levels in male and female samples.

This study suggests that ATR-FT-IR spectral analysis of hair fibres may detect breast cancer through increased lipid content changes linked to cancer presence.

This study measured estradiol and progesterone in the scalp hair of pre- and postmenopausal women using immunoassay, but found no statistical significance in hormone concentration differences between the groups.

This study observed that repeated hair follicle sampling is feasible and reliable for measuring FMR1 mRNA and FMRP in individuals with Fragile X syndrome, supporting its use in longitudinal studies.

This study suggests that hair analysis could serve as a diagnostic tool for detecting calcium channel activity, which influences hair calcium levels and may indicate calcium deficiency or related disease states.
