This study found that commercially available dyes penetrate up to 1.2 mm into human skin, with Indocyanine Green binding to cell proteins and showing a shift in absorption peak.

This study analyzed the distribution of adhesion molecules and extracellular matrix components in human fetal skin, suggesting their roles in hair follicle development.

In this study, polydopamine emerged as a safe and effective alternative to traditional hair dyes like PPD for dyeing gray hair permanently, showing resistance to detergents and causing less toxicity and hair loss in mice.

This study suggests that αMSH may play a regulatory role in human dermal papilla cells, potentially influencing immune and inflammatory responses in hair follicles, which could contribute to inflammatory alopecia.

This report describes two patients with ichthyosis linearis circumflexa exhibiting symptoms resembling Netherton's disease, noting multiple hair shaft defects and discussing a possible connection to aminoaciduria.

This study found that 17β-estradiol inhibited RANTES production in human keratinocytes by suppressing nuclear factor κB activity, suggesting a potential mechanism for 17β-estradiol's modulation of psoriasis-related inflammation.

This review discusses the range of diseases caused by mutations in keratin intermediate filament genes and presents no new clinical findings; the authors note the diverse phenotypes within this molecular category.

Oral retinoids are effective for severe skin conditions but require careful use due to side effects.

This study observed that in vitro exposure to dihydrotestosterone worsened COVID-19 spike protein-induced endothelial injury, while spironolactone showed potential in reducing this effect, suggesting a rationale for further evaluation in treating COVID-19.

This retrospective study documented various skin diseases in alpacas, reporting bacterial infections as the most common, along with other conditions described for the first time.

This review covers various disorders of cornification and their treatments, offering clinical insights but reporting no new research findings.

This case report indicates that trichoscopy may significantly improve the diagnosis of Netherton syndrome by noninvasively identifying typical hair abnormalities without the need to pull hair.

This study found that DPCP treatment led to cosmetically acceptable hair regrowth in 38% of patients with chronic severe alopecia areata, while adding 5% minoxidil showed no significant clinical benefit.

In this study, knockout mice lacking the Cyp4f39 gene showed severe skin barrier dysfunction and high early mortality, suggesting its critical role in skin barrier formation and insights into ichthyosis pathogenesis.

This research reports a new autosomal recessive mutation in mice, 'lanceolate hair', causing generalized alopecia and hair shaft abnormalities, which may serve as a model for Netherton's syndrome in humans.

This article describes a framework for evaluating new health technologies by integrating quantitative evidence with qualitative assessments and using precedents to guide policy decisions, without reporting new clinical results.

This review covers the diverse cutaneous and systemic presentations of sarcoidosis in patients with skin of color, emphasizing the importance of early recognition to improve outcomes despite a generally poorer prognosis compared to Caucasians.

This review discusses current concepts on the role of retinoids in keratinization and does not report new clinical results; the authors emphasize the complexity of retinoid effects on skin.

In this study, 13-cis-5S*,8S*-epidioxy-5,8-dihydroretinoic acid was found to be significantly more cytotoxic to cancer cell lines than other retinoic acid analogs evaluated.

This case report describes a 4-year-old boy with Netherton syndrome, where trichoscopy importantly aided diagnosis and is recommended for all children with erythroderma.

This study found that ICAM-1 expression in murine skin is developmentally regulated and crucial for skin and hair follicle remodeling beyond its recognized role in immune responses.

This study identified eight isoflavone derivatives as potential nonsteroidal inhibitors of rat 5α-reductase using a pharmacophore model in virtual screening.

In this study, in vitro and in vivo models showed that chrysin enhanced the efficacy of docetaxel and reduced its adverse effects in non–small cell lung cancer treatment.

The new compounds may be more effective and cheaper than current treatments for conditions like baldness.

This study found that relatively low concentrations of 1,25(OH)2D3 stimulated human hair follicle and fiber growth, while higher concentrations inhibited growth in a whole-organ culture system.

This study provides evidence-based recommendations for the off-label use of topical vitamin D in treating certain skin conditions, but highlights the need for higher quality studies for further validation.

This study demonstrates that locally synthesized estrogen and androgen neurosteroids play opposite roles in long-term synaptic changes in male rats' medial vestibular nucleus, with testosterone-dihydrotestosterone mediating long-term depression and 17β-estradiol mediating long-term potentiation.

This review discusses the molecular mechanisms involved in hair and epidermal development, highlighting how studies on human inherited diseases and mouse models have deepened our understanding; it reports no new results.

This study found that dermatology leads in performing office-based cosmetic procedures compared to other specialties, with a focus on white, female patients aged 40 to 59.

This study reports that five new progesterone derivatives demonstrated inhibitory activity against the 5α-reductase enzyme and binding affinity for the androgen receptor in an in vitro hamster model.
