This study found that hair from the vertex posterior is a reliable sampling region for detecting zolpidem intake, showing consistent drug concentration and peak position compared to other scalp regions.

This study concluded that the liquid chromatography-mass spectrometry method developed is viable for accurately quantifying spironolactone and its metabolite canrenone in plasma despite interference from plasma components.

This study found that microplastics on the Lebanese Mediterranean coast transport various organic and inorganic pollutants, posing threats to marine organisms and potentially human health.

This study developed a method to quantify hormones in skin secretions and found that hormonal composition varies by sex and anatomical site.

This study found that sensitive scalp is characterized by increased pH levels, redness, altered sebum composition, and a disrupted microbiome, suggesting these features could inform treatment approaches.

This study suggests that decreased levels of dihydroceramide in hair may serve as a biomarker for the progression of alopecia.

This study found low concordance between distal and proximal hair cortisol concentrations during early pregnancy, particularly when measured with different assay methods.

QMSI effectively maps and quantifies drug distribution in skin tissues.

This study found that in HIV-infected men, erectile dysfunction was influenced by the duration of HIV infection but not associated with serum testosterone or HAART therapy.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

The researchers reported that epitestosterone treatment reduced eicosanoid levels generated by cyclooxygenases and lipoxygenases in rabbit liver samples with carrageenan-induced inflammation.

This paper discusses advancements in forensic hair analysis, emphasizing a novel DART–HRMS method that improves the accuracy and efficiency of detecting drug use timelines.

This study suggests that epithelial-derived Pop-Up Keratinocytes (ePUKs) may be a promising cell source for regenerative medicine due to their specific phenotypic traits and their influence on wound healing.

This study successfully applied an optimized LC-MS/MS method for accurately determining finasteride concentrations and assessing its pharmacokinetics in healthy volunteers.

This study concluded that finasteride granules are bioequivalent to finasteride tablets based on pharmacokinetic evaluation in healthy male volunteers.

This study developed analytical methods to better understand hair treatment with cosmetic formulations, revealing that active agents primarily adsorb on the hair surface during short washes.

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.

This study supports evaluating metabolic syndrome and insulin resistance in young males with advanced androgenic alopecia to potentially reduce future cardiovascular and type 2 diabetes risks.

This study found a higher prevalence of metabolic syndrome in patients with lichen planus, especially those with mucosal involvement, which is associated with increased cardiovascular and diabetes risk.

This study found that SA-MS hydrogel released Mo4+ ions which promoted healing of disease-impaired wounds by enhancing cell proliferation and angiogenesis, and through its photothermal effects addressed skin cancer-impaired wounds in mice.

This study found that older age and obesity are predictors of metabolic syndrome and insulin resistance syndrome among infertile Vietnamese women with PCOS.

New method quickly and accurately measures dexpanthenol in hair products.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study developed a new HPLC method for detecting prohibited substances like minoxidil and hydrocortisone in cosmetic products, achieving high sensitivity and successful application to real-world samples.

This study developed a sensitive method to precisely determine hair lipid composition, demonstrating specific lipid changes from the root to the tip in untreated hair fibers from two women.
