This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

This study suggests that 1,25-dihydroxyvitamin D(3) and fibroblast growth factor 23 form a crucial axis in regulating phosphate balance, akin to its role in calcium regulation, and explores novel VDR interactions including with curcumin.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This study found that frontal and frontoparietal hair recession is relatively common in women, especially after menopause, and may not indicate abnormal androgen metabolism absent other virilization signs.

This study developed a framework to handle missing participant data in systematic reviews for continuous outcomes, finding varied impacts on confidence in effect estimates across reviewed cases.

This paper reviews adverse events related to hedgehog pathway inhibitors in advanced basal cell carcinoma patients, reporting no new clinical results but aiming to inform healthcare professionals for improved patient care.

This review discusses best practices for minimizing complications with dermal fillers and provides guidance based on expert consensus, yet it reports no new clinical results.

This study describes the development of the BASP classification system, providing a universal and systematic approach for classifying pattern hair loss in both men and women.

This review discusses the functions and potential therapeutic targeting of TRP ion channels in the skin, noting their involvement in both physiological processes and various pathological conditions, but reports no new experimental results.

This study found that T cytokeratins appear more gradually and with complex coexpression patterns in developing nail structures compared to the more abrupt transition in hair follicles.

This review discusses the disproportionate negative impact of the COVID-19 pandemic on individuals with chronic medical conditions and calls for strategies to protect these vulnerable populations.

This review discusses the mechanisms and storage of particles in hair follicles and presents no new experimental results, highlighting the need for further research in their safe application in dermatology and cosmetics.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

This study observed a high prevalence of androgenetic alopecia in patients hospitalized with severe COVID-19, with 79% of men and 42% of women affected, suggesting a potential link between androgen sensitivity and COVID-19 severity.

This study reports that Iressa, an anti-cancer agent, commonly causes acneiform eruptions and xerosis as cutaneous side effects, similar to other agents targeting epidermal growth factor receptors.

This study suggests that miniaturization in pattern hair loss may occur abruptly and can be reversed with treatment, as supported by histologic evidence in finasteride-responsive patients.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This review discusses zinc's role as an essential trace element in human nutrition, particularly its importance in total parenteral nutrition, and reports no new clinical results.

This review discusses the mechanisms of wound healing and excessive scarring, highlighting the importance of understanding these processes for developing new therapies to prevent fibrotic scarring in large skin wounds.

In their study, Tim Spector and colleagues identified a new genetic association at chromosome 20p11.22 with male-pattern baldness, confirmed by the increased risk when combined with a known androgen receptor gene variant.

This study describes the PandaOmics platform, which uses AI and bioinformatics to identify new therapeutic targets and biomarkers for various diseases, demonstrating validation in laboratory and animal studies.

This article reviews the current ACR classification criteria for systemic lupus erythematosus, highlighting their dermatologic limitations, and proposes guidelines for a study to update these criteria.

This review discusses the association between cutaneous paraneoplastic syndromes and internal malignancies, noting that recognition of these skin disorders may help detect underlying cancers, but reports no new research findings.

This retrospective study concluded that PUVA treatment is generally ineffective for alopecia areata, with low effective success rates for partialis, totalis, and universalis types.

This study identified a genetic locus associated with idiopathic scoliosis in females, which might influence spinal gene expression and was previously linked to protection from early-onset alopecia.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

This systematic review reports that "COVID toes" and other skin manifestations can be initial signs of COVID-19, and advises immunosuppressive therapy adjustments only for infected or at-risk patients.

This review discusses various classification systems for patterned hair loss in both sexes and reports no new clinical findings, highlighting the Hamilton-Norwood and Ludwig systems as the most commonly used.

This study observed that postlaser hair removal hypertrichosis occurred in 0.6% of patients and appeared more common in darker skin types, but was a rare phenomenon overall.
