This study explored the structure and function of lipocalin prostaglandin D synthase, revealing its dual role in substrate catalysis and as a lipophilic ligand carrier, potentially informing future drug delivery design.

In this study, the administration of indole-based compounds, particularly L-Tryptophan and Tryptophol, to a PCOS-induced rat model resulted in an increased number of healthy ovarian follicles and a reduction in ovarian cysts compared to untreated rats, suggesting potential therapeutic efficacy.

This study found that treating hair with ATS, formed from fumaric acid and cysteamine, effectively improved hair quality by increasing moisture content and altering the internal structure of strong curls.

This tool was developed to enhance reproducibility and sensitivity in measuring partial hair regrowth in alopecia areata patients, particularly those undergoing JAK inhibitor therapy, using scalp photographs.

In this study, researchers developed an open-source browser-based tool to enhance the reproducibility and accuracy of SALT score calculations from scalp photos, aimed particularly at assessing partial regrowth in alopecia areata patients on JAK inhibitor therapy.

This paper reviews the surface degradation of hair and describes how combining 18-MEA with specific surfactants can maintain hydrophobicity on bleached and weathered hair surfaces.

This article updates a diagnostic tool (SALT II) for assessing hair loss by adding more precise measurements of scalp surface area, particularly useful for various types of alopecia.

In this mouse model study, researchers found that deleting the ASH2L gene in epidermal progenitor cells led to thinner epidermal layers, delayed hair follicle development, and reduced epidermal stem cell pools, with alterations in genes related to hair follicle development and the Notch signaling pathway.

This study found that scanning electron microscopy with argon sputter etching visualizes hair lipids at the cell membrane complex as distinctive convex structures, shedding light on their role and localization in human hair.

This study suggests that the outermost hair cuticle surface is rich in 18-methyleicosanic acid (18-MEA), supporting previous findings of its multilayer lipid and protein structure.

This study found that chemical treatments such as hair bleach and UV radiation significantly reduced the amount of 18-methyleicosanoic acid on the outer surface of human hair.

Nano-liposol with astaxanthin may improve antioxidant and wound healing effects.

This study introduced and validated the VESALT, a visual extension of the Severity of Alopecia Tool, finding it offers improved reliability and user-friendliness over SALT by incorporating pattern recognition and broader coverage, including non-scalp regions, in assessing alopecia areata severity.

This study developed a quantitative measure for scoring hair surface damage from SEM images and found it accurately classified hair damage caused by explosive blasts, similar to an existing classification system.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

This study found that a conditioner treatment using 18-MEA combined with a specific cationic surfactant effectively restored hydrophobicity and reduced friction on damaged hair surfaces.

This review discusses squaric acid dibutylester's use, effects, and safety in treating alopecia areata, but reports no new clinical results.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

In this study, Dodatek A operationalizes the Functional Androgen Axis framework by defining three system-level indices and an efficiency metric to describe androgen function, incorporating key methodological improvements and acknowledging significant limitations for future empirical validation.

This study found that oxidative treatment with peracetic acid dissociates some disulfide bonds in human hair fibers while maintaining the crystalline structure, suggesting different mechanisms stabilize different regions of intermediate filaments.

The study found that the combined administration of regulatory T cells and rapamycin improved outcomes in an experimental model of chronic graft-versus-host disease.

This research presents the Dodatek A model, elaborating on androgen function through new mathematical indices and methodological improvements, shifting focus from serum hormone concentrations to system interactions to better describe androgen activity comprehensively.

This study evaluated the safety and effectiveness of HASHA, a new hyaluronic acid injectable, for chin augmentation in adults with chin retrusion. HASHA significantly improved chin appearance and satisfaction over 12 months compared to controls, with only mild or moderate transient adverse events.

This study identified intramembrane proteolysis as a key feature of Astrotactin2 maturation, providing insights into its role in planar cell polarity hair patterning.

This study's simulations suggest that replenishing free 18‐MEA could restore damaged hair surface properties, highlighting the importance of optimal fatty acid spacing for maintaining hair integrity.

In this study, human hair-carboxymethylated protein analysis showed that weathering for over 2.5 years can obscure electrophoretic patterns, while cosmetic treatments did not cause significant changes.

This study found that perming and bleaching hair result in different distributions of cysteic acid, suggesting distinct damage mechanisms between the two treatments.
