This review examines the life cycle, biomarkers, and functions of hair follicle stem cells, emphasizing their role in hair loss therapy and other skin and hair disorders, but reports no new clinical results.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This review discusses advances in understanding the mechanisms behind radiation-induced skin reactions, highlighting recent insights into the roles of stem cells and immune cells in injury mitigation and late carcinogenesis, as reported in the context of ionizing radiation exposure.

This study found that targeting connective tissue sheath contraction with an MLCK inhibitor may improve hair growth in androgenetic alopecia by reducing premature hair regression caused by ectopic apoptosis of hair follicle progenitor cells.

This case report describes a 68-year-old patient with mild Sars-Cov2 infection who developed rapidly progressing bullous and necrotic skin lesions leading to osteomyelitis.

This ex vivo study reported that a 645-nm wavelength red-light laser can penetrate and reach cells in the various layers of swine oral mucosa and periosteum tissue samples.

This study found that blocking apoptosis during the catagen phase in mice disrupts hair follicle stem cell niche architecture, delaying subsequent hair regeneration cycles.

In this study on C57BL/6 mice, researchers found that cadmium chloride exposure led to metabolic disruption, accelerated skin aging, and impaired hair regeneration, with more severe effects observed at higher doses.

This study found that high-dose minoxidil, a potassium channel opener, may protect neuronal tissue from damage following transient focal cerebral ischemia in mice.

Caspase-7 has functions in skin and hair that are not related to cell death.

Mesenchymal cells can significantly boost human hair growth and longevity.

This study found that oxidative stress in hair follicle melanocytes contributes to premature aging and apoptosis, providing insights into graying as a model for studying aging and testing antiaging therapies.

This study found that excessive consumption of cloves in mice caused toxic changes in the liver, including structural damage and cell death, but concluded these effects are not considered dangerous.

This retrospective analysis of male patients undergoing hair restoration surgery for androgenetic alopecia found that postoperative edema was the most common complication, occurring in 42.47% of cases.

This review evaluates neck rejuvenation techniques, including cervical rhytidectomy, and discusses potential surgical complications, without presenting new clinical findings.

This study documented a variety of skin lesions in COVID-19 patients, indicating that skin rashes might be an early or sole symptom of the disease.

In this study, four cases of neck carbuncle were treated, revealing that fire needle therapy combined with topical drugs offers less trauma, smaller scars, and faster recovery compared to surgery in early stages, but surgical debridement is essential for more advanced cases.

This case report describes an instance of hair thread tourniquet syndrome in an infant, successfully treated through surgical release of the constricting hair.

This article reviews cultural differences in the incidence of hair-thread tourniquet syndrome and finds it may be less prevalent in Iranian children compared to Europe, possibly due to social and cultural factors.

This review discusses hair tourniquet syndrome, highlighting its potential for delayed diagnosis and the association with maternal telogen effluvium, but reports no new clinical results.

This review summarizes fundamental concepts and recent advancements in hair follicle biology, including insights from mouse models into broader molecular and cellular processes relevant to regeneration and development.

Accidental injection of hyaluronic acid caused temporary hair loss and skin damage, but treatment restored hair and healed the skin.

This article discusses the development and research applications of human hair follicle organ culture techniques, highlighting its potential to explore biological processes beyond dermatology.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

In this laboratory study, researchers observed that mouse vascular endothelial cells exhibit dynamic changes after exposure to ionizing radiation, including a transient endothelial subpopulation that facilitates vascular-epidermal communication and skin repair, with shifting roles in angiogenesis and immune surveillance over time.

This case report highlights a rare instance of filler-induced alopecia in a young woman following hyaluronic acid filler injections, showing successful hair regrowth and scar resolution through multidisciplinary treatment including hyaluronidase and other therapies, emphasizing early recognition and intervention.

This study found that adding cell adhesion-linked gene expression variables improved the identification of patients with SLN metastases within 90 days of melanoma diagnosis compared to using clinicopathologic variables alone.

This study found that lncRNA H19 may regulate CTGF expression in KGN cells by acting as a "sponge" for miR-19b, potentially influencing polycystic ovary syndrome development.

This review summarizes recent research on the molecular properties and functions of L-PGDS and PGD2, but reports no new findings, highlighting their pathophysiological roles and guiding future studies.

This study found that WWOX deficiency in mice leads to impaired skin development, reduced epidermal thickness, and significant hypothermia due to disrupted cell proliferation and homeostasis.
