This review discusses recent advances in polydopamine-based biomaterials and their growing potential in personalized medicine, but reports no new experimental results; the authors highlight both opportunities and challenges for future applications.

This study developed a new spectrophotometric method to accurately measure finasteride levels in pharmaceutical formulations using a reaction with NBD-CL.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

This review discusses valproate-associated hair abnormalities, describing their common and benign nature, and outlines management strategies, though new clinical results are not provided.

This study found that cPPARγ and dnPPARγ isoforms are differentially expressed in healthy human skin, suggesting that PPARγ modulators may have compartment-specific effects depending on isoform presence.

This study found that acid and alkaline phosphatases serve different functions in Beagle dog skin, with ALP primarily involved in growth processes and ACP in phospholipid breakdown.

This review discusses the role of reactive oxygen species in regulating oscillating apoplastic pH gradients and growth in plant root hairs and pollen tubes, reporting no new experimental results.

This review discusses the role of RDH12 in vision, its structural and functional aspects, and related disease mechanisms, but reports no new clinical results; it aims to support therapy development for inherited retinal dystrophies.

In this study, progesterone showed anticonvulsant effects in mice via a mechanism that is at least partially independent of its metabolism to THP, without significant psychotoxicity.

This study indicates that individuals exposed to PPD mount varying immune responses, with either tolerance, subclinical inflammation, or allergy, suggesting no true non-responders to PPD.

This study found that Phellodendri Cortex Ex may reduce prostate tissue damage and inhibit $5{\alpha}$-reductase gene expression in a rat model of benign prostatic hyperplasia, suggesting potential therapeutic benefits.

This study identified a new enzyme, skin l‐tryptophan‐2,3‐dioxygenase, that may play a role in rat hair growth regulation, showing increased activity during peak hair growth periods.

This study found that progesterone and its metabolite, allopregnanolone, provided anti-anxiety and anti-depressive effects in female mice, potentially independent of nuclear progestin receptors but requiring 5α-reduction and estradiol's influence on brain-derived neurotrophic factor.

This study found that adding fexofenadine to DPCP treatment in non-atopic Alopecia areata patients did not significantly improve hair regrowth, but it did significantly reduce treatment-related discomfort.

Some people have a genetic variation that makes them less effective at breaking down drugs.

This study reported that mice on a phenylalanine-deficient diet showed symptoms such as weight loss, gastric dilation, and thymic depletion, which echo human phenylalanine deficiency manifestations.

This study found that specific TRPM5 modulators are unlikely to directly affect sebaceous glands, but safe TPPO analogues may provide moderate lipogenic and anti-inflammatory effects beneficial for dry skin conditions.

In this study, formulations of a typical lotion shampoo with ethanol or propylene glycol increased the in-vitro release rate of zinc pyrithione, an anti-dandruff agent.

This study found that α-ketoglutarate protected dermal papilla cells from oxidative stress by enhancing the Nrf2 pathway and mitigating cell damage through the ERK/Nrf2 axis.

This study observed that autologous PRP and PDRN injections improved hair thickness and density in women with pattern hair loss, with combined therapy showing greater improvement in thickness than PDRN alone.

This study reports that the differential expression patterns of three retinaldehyde dehydrogenases suggest a regulated need for retinoic acid synthesis in various organs during late mouse organogenesis.

This study found that VDR polymorphisms, particularly ApaI and FokI variants, are associated with hormonal and metabolic disturbances in women with PCOS, with notable variations across different ethnicities.

This study highlights a rare case of vitamin D-dependent rickets type 2A caused by a heterozygous mutation in the vitamin D receptor gene, emphasizing the complexity of managing this condition with high-dose calcium and vitamin D therapy.

This study investigated alkaline phosphatase activity in scalp biopsies from patients with alopecia areata and totalis, but provides no new conclusive clinical results.

This article reviews the role and clinical applications of 1,25-dihydroxyvitamin D3 and parathyroid hormone-related peptide in dermatology, with a focus on psoriasis treatment, and reports no new experimental findings.

This study found that aged tritiated thymidine breaks down and incorporates into cytoplasmic macromolecules, not DNA, suggesting caution in its use.

This study found that some synthesized heterocyclic derivatives showed promising 5α-reductase inhibitor, antiviral, and anti-tumor activities, surpassing several reference drugs in effectiveness.

Hair dye with para-phenylenediamine can cause skin depigmentation.

This study found that the progesterone metabolite 3α-THP increased the proliferation and gene expression of human glioblastoma cells, suggesting a role in tumor progression.
