This study reports that retinol acetate inhibited the pro-oxidant effects of benoxaprofen on polymorphonuclear leucocytes in vitro.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This study found that Pannexin 3 plays a crucial role in skin development by regulating the transcription factor Epiprofin, affecting keratinocyte differentiation and hair follicle regeneration in mice.

This study identified specific genetic variants as the cause of visual impairment and non-syndromic alopecia in two brothers, reinforcing the link between PDE6H variants and achromatopsia and LPAR6 variants and alopecia.

This study found that sinapic acid promotes the browning of 3T3-L1 adipocytes and may offer therapeutic potential for obesity by influencing mitochondrial biogenesis through the p38 MAPK/CREB signaling pathway.

This study found that ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.

This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.

This case series observed that macular changes from popper use can resolve completely after cessation, even in individuals with chronic use.

This study provides evidence that human skin contains genes and enzymes necessary for producing serotonin and melatonin.

This study found that apocynin restored collagen production, reduced DNA damage and senescence, and protected skin stem cells from aging in UVB-exposed human keratinocytes.

In this study, silencing P-cadherin in human scalp hair follicles reduced melanogenesis and associated protein expression, suggesting P-cadherin is crucial for normal hair pigmentation via GSK3β-mediated Wnt signaling.

This study identified a novel mutation in the coproporphyrinogen oxidase gene, contributing to hereditary coproporphyria in a family, with decreased enzyme activity observed in the affected members.

In this nonrandomized controlled trial, tenon capsule injection of platelet-rich plasma improved capillary perfusion and may enhance short-term vision in patients with acute nonarteritic anterior ischemic optic neuropathy.

This study found that osteopontin mRNA is abundantly expressed in dermal papilla cells during the catagen phase of hair growth in rats, suggesting a role in this phase.

This case report suggests that intralesional cidofovir may be a consideration for treating squamous cell carcinoma, as it showed a successful outcome without systemic toxicity, although surgical excision remains preferred.

This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This study identified a cytochrome P450 enzyme, CYP-pa1 from Pseudonocardia autotrophica, as responsible for the specific hydroxylation of cyclosporin A at the 9th N-methyl leucine, suggesting potential for biotechnological applications.

This study found that unilateral topical latanoprost use for glaucoma was associated with hypertrichosis and increased pigmentation of eyelashes in the treated eye compared to the untreated eye.

This study found that androgenetic alopecia patients had significantly lower serum levels of paraoxonase 1, which correlated with disease severity and suggests a role of oxidative stress in its pathogenesis.

This review discusses pyrene excimer nucleic acid probes for detecting biomolecules and protein-DNA interactions and reports no new experimental findings.

This editorial reviews how photobiomodulation therapy might effectively treat both hyperpigmentation and depigmentation skin disorders, but reports no new clinical results.

The researchers reported that protocatechuic acid reduced melanin synthesis and enhanced antioxidant activity in cultured human hair follicle melanocytes, indicating potential for skin whitening applications.

This commentary highlights the importance of additional sun protection for individuals with alopecia, noting that common headwear like baseball caps may provide insufficient photoprotection for the scalp.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

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.
