This article reviews new drug therapies for endocrine disorders, discussing specific treatments such as trilostane for hyperadrenocorticism and various insulins for diabetes mellitus, but it reports no new clinical findings.

This exchange discusses interpretations of syphilitic chancres, noting disagreement over whether multiple lesions are atypical given historical references that describe primary chancres as often being single.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

This review discusses the significant role of Wnt signaling in skin development, homeostasis, and disease, highlighting recent advances in understanding its diverse functions, but reports no new experimental results.

In this study, researchers developed a method to control the valence states of Mo in nanozymes, optimizing their activity for ROS-related therapies, particularly acute kidney injury treatment, and enabling real-time monitoring with photoacoustic imaging.

This article reviews the role of polarity proteins in epidermal morphogenesis and homeostasis and discusses how their alteration may contribute to skin disease, but reports no new experimental findings.

This review compares the CO2 and Er:YAG laser treatments for acne scars, noting that while CO2 lasers offer deeper tissue penetration for severe scars, Er:YAG lasers pose a lower risk of post-inflammatory hyperpigmentation, and recommends personalizing treatments and considering combination therapies.

This study found that while new treatments like Optilume, Rezum, and Aquablation have minimal risks of sexual dysfunction, they offer less improvement in lower urinary tract symptoms compared to traditional surgeries like TURP, though Aquablation does reduce ejaculatory dysfunction more effectively than TURP.

This case report documents new hair growth in a 57-year-old man with androgenic alopecia after receiving gefitinib treatment for non-small-cell lung cancer.

This study found that adjusting CO2 laser parameters to 55 W and 0.1–0.15 seconds improved hair graft survival rates to 80-90% in Oriental hair transplant patients.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This study found that laboratory and African spiny mice have distinct spatiotemporal patterns in wound-induced hair neogenesis, with the Twist1 pathway playing a central role in epidermal-dermal interactions for hair primordia formation.

This review provides an overview of microneedle-assisted photomedicine, detailing diagnostic and therapeutic strategies, design principles, and challenges for translating this approach to skin disease management.

This study found that both 5-ALA and Photofrin can effectively destroy human microvascular endothelial cells in vitro and cause tissue necrosis in vivo, with Photofrin showing greater efficacy at lower concentrations or power densities.

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.

This review discusses five popular resurfacing technologies for facial rejuvenation, highlighting their role in achieving smoother, healthier, and younger-looking skin, and reports no new clinical results.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This study found that abolishing H3K27me3 in mouse skin by targeting Ezh2 and Ezh1 affects hair follicle development and epidermal behavior, revealing functional differences between these tissues.

This review discusses mesenchymal–epithelial interactions in hair follicle development and cycling, highlighting recent insights without reporting new experimental results.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This study found that Smad7 perturbs hair follicle development while promoting sebaceous gland formation by antagonizing Wnt/β-catenin signaling in transgenic mice.

This review updates the understanding of fibroblast heterogeneity in wound healing, discussing advancements in fibroblast roles and potential therapies, but it reports no new clinical results.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

Different types of stem cells and their environments are key to skin repair and maintenance.
