This review discusses the role of lncRNA Xist in cell growth regulation and disease development, particularly cancer, and reports no new experimental results.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

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.

Hair cortisol analysis can help diagnose stress-related conditions but needs more refinement for widespread use.

This study identified genetic variants in the Trichohyalin gene that account for approximately 6% of the variance in hair morphology among Australians of European descent.

This review examines the roles and benefits of chitosan in cosmetics and oral hygiene, highlighting its potential in the cosmeceutical market, but it reports no new results.

This study identified collagen XXII as a novel extracellular matrix protein specifically present at tissue junctions, where it functions as a cell adhesion ligand for skin epithelial cells and fibroblasts.

This study found that the skin microbiome in patients with hidradenitis suppurativa differs significantly from healthy controls, suggesting a potential link between microbial imbalance and the disease.

This study found that surgical deactivation of migraine headache trigger sites can significantly reduce migraine symptoms, with 92% of patients reporting at least a 50% reduction in migraine frequency, duration, or intensity.

This study found that hair cortisol levels were significantly higher in patients with Cushing's Syndrome compared to healthy controls, suggesting hair analysis can provide historical information on cortisol exposure.

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.

This study found that the tetracycline-regulated transcription system effectively controls conditional gene expression in the mouse epidermis, allowing suppression and activation of specific genes with doxycycline.

This study observed that 32% of COVID-19 patients experienced persistent symptoms, including fatigue, dyspnea, and loss of taste or smell, 30 to 45 days after their initial diagnosis.

This study found that transgenic expression of COX-2 in mouse basal keratinocytes causes epidermal hyperplasia and certain dysplastic features at specific body sites.

In this study, researchers found a significant positive association between cortisol levels in hair and feces of domestic cats and dogs, suggesting hair cortisol assays could be a viable option for monitoring chronic stress.

This review discusses the bioactive phytochemical and biological activities of Psoralea corylifolia, emphasizing its potential therapeutic uses, and reports no new clinical results; the authors call for further clinical trials.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This study developed and validated a method for extracting cortisol from human and animal hair, suggesting its potential as a biomarker for assessing chronic stress exposure.

This review discusses recent advancements in congenital adrenal hyperplasia research, including improved diagnostic techniques, alternative treatments, and insights from long-term outcome data, but it reports no new clinical results.

This review discusses biological sex differences in COVID-19 outcomes and reports no new clinical results; it identifies a need for studies to clarify how sex influences disease progression.

This review discusses side effects and allergy contact dermatitis caused by essential oils in cosmetic products and reports no new clinical results.

This literature review discusses recent advances in using essential oils and their components in cosmetic products, highlighting their diverse benefits and challenges in formulation due to varying chemical profiles, as well as addressing safety considerations for these natural ingredients.

This article reviews the empirical use of algae in traditional remedies and highlights the need for scientific understanding of algae's bioactive compounds used in cosmetics without providing new experimental results.

This study found that Myc activation in mouse epidermis impairs keratinocyte adhesion and motility by downregulating extracellular matrix and cytoskeleton proteins, affecting hair lineage differentiation.

In this study, researchers found that in hairy guinea pig skin, minoxidil delivered via 40-nm nanoparticles had higher skin penetration than 130-nm nanoparticles, indicating nanoparticle size affects permeation.

This study found that the mammalian hairless gene encodes a corepressor protein that interacts with thyroid hormone receptors, providing insights into hair loss syndromes in humans and mice.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study found that mutations in the K17 gene underlie both pachyonychia congenita type 2 and steatocystoma multiplex phenotypes, regardless of the specific mutation involved.
