This study found that poly(adenosine diphosphate-ribose) synthesis in human skin varies by cell type and condition, with distinct patterns in psoriatic, cancerous, and normal tissues.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This case report describes a 49-year-old woman with Sweet syndrome who experienced complete resolution of skin lesions after a prednisone treatment regimen.

This study in mutant mice found that Bmpr2 and Acvr2a are individually redundant, but together essential for normal hair follicle development, with their reduction causing rapid hair cycling and graying.

This review discusses the relationship between acne, body hair, and androgenic stimulation in adolescent girls, emphasizing treatment decisions based on disease severity rather than endocrine findings.

In this study, ob/ob mice were found to have a prolonged telogen hair cycle phase from 10 to 24 weeks, suggesting their potential as a model for studying telogen effluvium.

This case report describes a 22-year-old female with pseudoglucagonoma syndrome, where necrolytic migratory erythema resolved after treatment with topical steroids, emollients, and intravenous protein infusions, despite normal glucagon levels and absence of a glucagon-secreting tumor.

This study found that hyperbaric oxygen treatment in rats led to structural changes in epidermis and dermis, including decreased E-cadherin expression and increased connective tissue.

This study found that in Hutchinson–Gilford progeria syndrome, iPSCs committed to the keratinocyte lineage faster than normal cells, with LEF1 expression reduced and a partial rescue of the phenotype achieved through adenine base editing.

This study found that depleting HIF-P4H-2 in FoxD1-lineage cells in mice led to disrupted hair follicle development, resulting in truncal alopecia but normal cranial hair, suggesting its crucial role in hair homeostasis.

This study found that the expression of CD117 and platelet-derived growth factor receptor α differs in alopecia areata tissue compared to normal controls, with platelet-derived growth factor receptor α correlating with disease severity.

This chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

This article discusses the psychological impact of skin imperfections and suggests establishing a Cosmetic Dermatology Service within public health systems to address these issues ethically.

This case report describes a 2-month-old infant with a severe seborrhea-like skin eruption and respiratory distress, similar to symptoms that led to a sibling's death from Gram-negative septicemia.

This study by Bansaccal et al. found that skin with higher levels of type I collagen density and elasticity in the dermis can inhibit basal cell carcinoma development and spread by acting as a natural barrier against cell reprogramming in mice.

In this viewpoint, researchers discussed the possible role of the developmental origin of scalp dermis in influencing the specific pattern of hair follicle miniaturization seen in male pattern hair loss, noting that frontal follicles are more susceptible while occipital follicles remain largely terminal.

This study describes a new method for isolating intact human eccrine glands from scalp follicular units, potentially advancing research on sweat gland physiology.

This case study identifies early-onset trichotillomania in a 4-year-old girl, treated with behavioral interventions that led to decreased hair pulling and regrowth over three months.

This chapter provides an overview of terminology for various skin lesions, including primary and secondary types, but does not report new findings or results.

A woman got a scalp condition from using latanoprost, but it improved after stopping the drug and starting other treatments.

This study found that a new hair loss lotion containing various cosmetic ingredients significantly increased total hair fibers and anagen hairs in individuals with androgenetic alopecia and telogen effluvium, while also improving visual hair characteristics and receiving positive user feedback without adverse effects.

This article reviews the historical development and advancements in hair transplant techniques, from punch grafting in the 1950s to the modern follicular unit extraction, and reports no new clinical results.

This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.

Burn scars form abnormally due to changes in wound healing, and more research is needed to improve treatments.

This study suggests that vitamin D-upregulated protein 1 (VDUP1) might play a unique role in regulating the differentiation of epidermal cells.

This study found that 660 nm laser treatment and povidone iodine both eradicated Pseudomonas aeruginosa infection in mice wounds, with the laser enhancing healing, and the combination provided additive or synergistic healing benefits.

The man's occipital hair loss was due to temporal triangular alopecia, not alopecia areata.

This review discusses the role of reactive oxygen species in wound healing, highlighting potential strategies like mitochondrial-targeted antioxidants for managing non-healing chronic wounds, and reports no new clinical results.

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 study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.
