The document concludes that secondary syphilis cases are increasing and often misdiagnosed, pityriasis rubra pilaris can be distinguished from psoriasis by skin cell features, and different skin layers produce specific components during skin repair.

This narrative review explores how exercise might help maintain skin homeostasis disrupted by protein deficiency, potentially by promoting processes like increased collagen synthesis and stimulating anti-inflammatory effects, though the exact mechanisms are not entirely understood.

In this study, researchers found that the protein Twist2 plays a crucial role in scarless wound healing in early embryonic mouse skins, with its knockdown leading to visible scarring and defective hair follicle formation, suggesting potential therapeutic targets for reducing scars and promoting regeneration.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

Multi-pass laser skin treatments improved healing, reduced pain, and had no major complications.

Minoxidil showed a 30% success rate for hair growth in a study, and various skin treatments were effective, but some had limitations or side effects.

This study found distinct gene expression profiles in the parietal and occipital scalp of individuals with androgenetic alopecia, linked to developmental origins and susceptibility to hair loss, offering insights into genetic and epigenetic factors involved in AGA.

This review summarizes the use and neonatal outcomes of chemotherapy during pregnancy, noting its potential for safe use in the second and third trimesters, and reports no new clinical results.

A new hair transplant method showed promising results and a study found how deep a CO₂ laser can penetrate skin.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

This narrative review discusses the structure and functions of the skin, focusing on its barrier role, self-repair, thermoregulation, and immune functions, and reports no new experimental results.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

This study found that telocytes are present in the human dermis, suggesting a potential role in skin homeostasis, remodeling, regeneration, and repair.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This summary explains the different types of wrinkles, their causes, and their distinct microanatomical characteristics, noting that each type may respond differently to treatments.

This study found that drug delivery through human scalp skin may be more effective for lipophilic and hydrophilic drugs compared to abdominal skin, highlighting the potential of intrafollicular delivery methods.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

This review discusses the challenges and contradictions in understanding nanoparticle penetration and toxicity in human skin, emphasizing the need for standardized testing and further research on particles smaller than 10 nm.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

This study demonstrated that phosphatidylcholine liposomes can deliver calcein and melanin into hair follicles and shafts in mice without significant penetration into the dermis, epidermis, or bloodstream.

This study found that a 70% methanol extract from red ginseng stimulated hair growth in mouse vibrissal follicles, suggesting its bioactive components, particularly certain ginsenosides, may promote hair growth.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This review discusses the embryonic origins and characteristics of various stem cell populations in the skin, but it provides no new experimental results.

This abstract omits specific findings and does not provide new research results.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

Minoxidil affects collagen-related genes, potentially helping treat fibrosis.

In this study, microneedles combined with finasteride nanostructured lipid carriers (FIN-NLC-MNs) were found to enhance skin penetration and specifically target hair follicles, promoting hair growth and gene regulation in androgenetic alopecia.

This study found that alopecia in captive Rhesus macaques may be linked to chronic hypersensitivity dermatitis with CD4+ cell inflammation, possibly influenced by altered housing and reduced pathogen exposure.

This study utilized magnetic resonance imaging to noninvasively visualize and differentiate skin structures in rat skin, finding a significant correlation between MRI data and histological areas.
