This study observed that cathepsin L and transglutaminase 3 colocalize in the human hair bulb and nail matrix, suggesting their involvement in terminal differentiation within these epidermal appendages.

This article reports no new results; it is a publication of meetings, transactions, and society news from the International Journal of Dermatology.

This article discusses the use of forensic DNA phenotyping to infer physical characteristics from biological samples without a reference sample, aiding investigations but raising ethical and legal concerns.

This study found that metabolic adaptations in skin epithelial stem cells, specifically redox ratio recovery and glycolytic flux modulation, define competitive outcomes between wild-type and mutant cells in different oncogenic environments.

This study introduces PROMETHEUS, a framework that organizes causal claims from scientific texts into navigable and persistent "causal atlases," enhancing research by highlighting localized evidence, agreement, and contradictions within complex data sets.

This review discusses the diverse functions and therapeutic potential of ectopic olfactory receptors throughout the body, emphasizing their roles in various cellular processes and potential in cancer detection and therapy, but reports no new clinical results.

This study observed that a self-emulsifying drug delivery system for finasteride significantly enhanced bioavailability in rats compared to commercial tablets, but the formulation was found to be thermodynamically unstable.

In this study, the genotoxic effects of the 2020 harmful algal bloom event were linked to specific toxic algal groups affecting Tradescantia plants, making Trad-SHM and Trad-MN tests suitable for evaluating HABs' toxic potential.

This review concludes that global literature supports the lipidosterolic extract of Serenoa repens as efficacious and safe for treating lower urinary tract symptoms, with some studies showing equivalence to common pharmacologic agents.

This study presents a rapid method for detecting multiple xenobiotics in urine, effectively identifying 45 compounds banned in sports with detection limits below WADA's performance levels.

The researchers reported that the aqueous extract of Urtica fissa E.Pritz inhibited 5α-reductase activity in vitro.

In this study, researchers developed a sensitive assay to measure the inhibition of steroid 5-α reductase (5AR) by chemicals like finasteride and dutasteride, revealing species-specific differences in inhibitor efficacy between human and fish cell lines.

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

This piece reflects on the past year of editing the Assistants' Corner and presents no new research findings.

This article proposes a classification system for hair casts to resolve confusion in existing literature and describes a staining technique to distinguish peripilar keratin casts from other hair disorders, without providing new clinical results.

This study demonstrated that optical coherence tomography effectively detects significant changes in hair structure caused by steroid treatment, suggesting its potential use in doping control and clinical therapy monitoring.

This study developed and validated a label-free assay using LC-MS to screen for S5αR inhibitors, identifying Thai herbal extracts, Impatiens balsamina L. and Curcuma longa L., as promising sources.

This study developed and validated a sensitive and rapid method to simultaneously measure alfuzosin and dutasteride in human plasma, enabling high-throughput analysis for pharmacokinetic and bioequivalence studies.

In this study, researchers used single-cell RNA sequencing to identify seven cell types, including distinct steroidogenic and immune cells, in the tumor microenvironment of a case of ovarian SCT-NOS, providing insights into its cellular heterogeneity and molecular mechanisms related to hyperandrogenism.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

In this study, adults with significant alopecia areata were surveyed on their preferences for JAK inhibitor treatments, revealing a strong priority for scalp hair regrowth effectiveness and quicker initial regrowth over dosing convenience.

This study found that retinoic acid and a retinol complex formulation showed different permeation and compound localization in a skin equivalent model, with unique lipid changes observed with only the retinol formulation.

This study revealed that Patched receptors establish a Hedgehog signaling gradient in developing hair follicles, which may influence their formation and potentially offer a diagnostic tool for distinguishing Hedgehog-driven tumors.

This study found that ocular and mucocutaneous sequelae are common in SJS/TEN survivors, with exposure to sulfadoxine and severe acute ocular involvement identified as significant risk factors for ocular sequelae.
