In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

This editorial synthesizes research on UV-induced skin damage, highlighting potential therapeutic strategies by mapping cellular changes, identifying molecular mechanisms, demonstrating melanocyte protection, and proving combination therapy effectiveness in conditions like vitiligo.

This review reports on the effects of aging on hair characteristics such as pigmentation, growth, and structural properties across genders and ethnicities, highlighting the importance of scalp health and suggesting cosmetic solutions to improve the appearance of aged hair.

This article reviews the anatomy and pathology of skin and hair to aid in diagnosing skin diseases and discusses potential therapies, without reporting new clinical results.

This study presents the first reported case of woolly hair nevus appearing during adolescence, with significant improvement observed 5 years later and structural changes in the hair documented.

This review discusses the role of tissue mechanics and extracellular matrix in skin aging processes and highlights potential therapeutic strategies, but reports no new clinical results.

In this study, hyperplastic layers of scabietic sheep skin showed expansive keratin labeling, indicating altered keratin expression compared to healthy skin.

New methods for growing skin cells can improve skin grafts by building blood vessels within them.

This study identified the TALE homeodomain transcription factor Meis2 as a crucial regulator for the maturation and end-organ innervation of certain mechanoreceptors in mice, with its absence leading to altered sensory neuron structure and impaired touch sensitivity.

This paper discusses the challenges of diagnosing drug eruptions, emphasizing the nonspecific patterns and unclear pathomechanisms, and calls for further research using new biologic drugs to understand these reactions better.

This review highlights that skin organoids, advanced three-dimensional models mimicking human skin, are emerging as effective alternatives to traditional culture models and human skin, overcoming limitations of two-dimensional systems and ethical concerns, and are being increasingly used in areas like developmental biology and disease modeling.

This review discusses the use of human-to-mouse xenografting to study human skin processes in vivo, highlighting its importance for understanding skin regeneration and pathology while identifying knowledge gaps and challenges in applying these findings to human skin.

This study found no qualitative skin differences during development between mutant hairless USP mice and BALB/c mice, except for enlarged cysts in the hairless strain.

This study identified a novel bi-allelic missense variant in the DSC3 gene linked to severe Hypotrichosis with Recurrent Skin Vesicles in a Saudi child, supporting its role in the condition.

In this study, CTCF was found to play essential roles in epidermal differentiation and skin barrier formation, simultaneously acting as a suppressor of epithelial inflammatory responses in mouse skin.

This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.

This study suggests that a portable OCT system may be useful for the clinical diagnosis and evaluation of skin diseases and laser treatment outcomes.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

This review summarizes the effects and complications of bariatric surgery on skin, noting it can alter existing skin conditions like psoriasis and trigger new dermatoses, but provides no new clinical results.

In this study, researchers used tissue clearing techniques on human skin and scar tissue for the first time to render them optically transparent, with the aim of revealing atypical structures and improving protocols for observing scar tissue changes.

The study reported that combining the Follicular Closing Technique with the Franz diffusion cell is a valuable method for investigating follicular caffeine penetration in vitro, though kinetics differ from in vivo results.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This study found that mutant Cx43 impairs fibroblast function during wound healing and reduces hair follicle cell proliferation, likely contributing to hair growth defects in ODDD patients.

This article discusses various pruritic dermatoses that can occur during pregnancy, emphasizing the importance of physician skill in diagnosing and treating these conditions; it reports no new findings.

This study found that both subclinical and overt maternal hypothyroidism during pregnancy and lactation caused significant damage to the skin development of rat offspring, including pronounced hyperkeratosis and reduced hair follicle formation, with more severe effects observed in overt hypothyroidism.

In this study, researchers established a model using Mongolia Sheep hair follicles to investigate growth mechanisms, noting that adding insulin and hydrocortisone helped maintain follicle shape during extended culture.

This study suggests that the HCR risk allele within the PSORS1 locus may contribute to psoriasis susceptibility by altering gene expression related to skin structure and differentiation, although these changes alone might not result in clinical symptoms.

In this study of Angora goats, researchers found that HOXC13 and other genes were overexpressed during the active hair growth phase, suggesting a role in mohair structure.

In this study, the researchers successfully cloned and sequenced the hairless gene cDNA of Kunming mice, revealing high conservation and functional significance among various mammalian species.

This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.
