This study suggests that targeting the endocannabinoid system through pharmacological interventions may help reduce compulsive hair-pulling in individuals with trichotillomania.

In this study, oral administration of modified aloe gel significantly reduced liver enzymes AST and ALT and led to hair regrowth in carbon tetrachloride-treated albino mice after 33 days.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

Certain microRNAs may help treat alopecia areata by targeting immune pathways.

This case report describes a 29-year-old woman with longstanding alopecia areata who experienced improvement in her scalp hair loss after 7 years of topical treatment with squaric acid dibutylester.

This study observed that NSG-hu-BLT mice developed graft-versus-host disease characterized by CD8+ T lymphocyte-related cell death in the skin and liver, which may affect their utility in other research areas.

This synopsis reviews key dermatological advancements discussed at the British Association of Dermatologists meeting in 2011 and reports no new clinical results.

This study found that transgenic mice expressing IGF-1 in their skin showed significant skin changes, early hair follicle generation, and a higher propensity to develop tumors after chemical promotion, suggesting IGF-1's role in skin carcinogenesis.

This study reports that progesterone metabolism to DHP and THP is necessary for its neuroprotective effect against kainic acid excitotoxicity in ovariectomized rats, unlike the synthetic progestin MPA.

This case report describes acute liver injury in a 5-year-old Caucasian girl after ingesting the Chinese herbal product Shou-Wu-Pian, suggesting a potential link between this unregulated herbal remedy and hepatotoxicity.

This study suggests that activation of polyamine catabolism in K6-SSAT transgenic mice may significantly increase skin tumor development and progression to carcinomas following chemical induction.

This study found that dimethylarsinic acid significantly accelerates skin tumor development in hair follicle-targeted K6/ODC transgenic mice.

This study found that progesterone can inhibit spinal reflex potentiation in ovariectomized rats through GABA(A) receptor activity, mediated by neurosteroid metabolism rather than direct progesterone receptor action.

This study suggests that IL-1β produced by dermal papilla cells, regulated by protein kinase C, may inhibit human hair follicle growth through paracrine signaling.

This study reported that high ornithine decarboxylase expression and decreased keratin K1 and K10 expression may serve as useful markers for early stages of tumor development in mouse skin.

This study in a transgenic mouse model found that repressing overexpression of ornithine decarboxylase reduced papilloma development, indicating its role in tumor promotion sensitivity.

This study found that applying TPA to mice accelerated hair follicle regeneration by activating Akt and Wnt/ß-catenin signaling pathways, involving hair follicle stem cell proliferation.

This study found that proteolytic activities in murine skin vary with hair cycle stages, with significant collagenase activity during the early anagen phase.

This review summarizes recent advances in understanding intermediate filament structure and their implications for pathological mutations and human diseases, but it reports no new experimental results.

In this study, researchers established five new immortalized human dermal papilla cell lines from a male with androgenetic alopecia, which may serve as valuable tools for hair research.

This study found that vitamin D receptor expression is associated with proliferating keratinocytes, while retinoid X receptor α is linked to differentiating keratinocytes, suggesting differential targeting by vitamin D metabolites.

This study found that the cytokine-mediated signaling pathway is the primary pathway disrupted in skin after CO2 laser surgery.

This study found that TPA treatment induced expression of keratins K6 and K16 in mouse epidermis, with K6 expressed across all cell layers and K16 only in post-mitotic cells.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This study found that a new analytical approach revealed an increased brain pregnenolone level following finasteride treatment in a mouse model, suggesting potential for improved understanding of neurosteroid roles in brain excitability.

This study found that 1,2,3,4-tetrahydroquinoline derivatives, particularly N-methyl-7-amino-1,2,3,4-tetrahydroquinoline, may be excellent blue dye candidates for human hair, offering superior color purity, stability, and fastness compared to 2,3-dihydroindoles.

This study reports that hair follicle cultures are effective for gap junctional intercellular communication studies and can be used to assess the tumor-promoting activity of certain environmental chemicals.

This study found that a 4:1 combination of Rhynchosia nulubilis and Polygonum multiflorum extracts significantly promoted the proliferation of human dermal papilla cells and alleviated testosterone-induced cytotoxicity, suggesting potential for treating hair loss and related disorders through a synergistic approach.

This study introduced a new spectrofluorometric method using a synthesized organic fluorophore to effectively analyze darolutamide and thalidomide in pharmaceutical preparations and biofluids.

This report examines the mechanisms by which TCDD affects human epidermal and carcinoma cells, aiming to create a risk assessment model for halogenated aromatic compounds, but presents no new clinical results.
