The role of SFRP1 in human dermal papilla cell growth and its potential molecular mechanisms as a target in regenerative therapy.

Background: Secreted frizzled-related protein 1 (SFRP1) inhibits Wnt signaling and is differentially expressed in human hair dermal papilla cells (DPCs). However, the specific effect of SFRP1 on cell function remains unclear. Telomerase reverse transcriptase (TERT) representing telomerase activity was found highly active around the hair dermal papilla.

Dutasteride for the Treatment of Androgenetic Alopecia: An Updated Review.

Background: Androgenetic alopecia (AGA) is a common skin disease characterized by gradually miniaturized hair follicles, which manifests as progressive hair thinning and produces a bald appearance. Currently, finasteride is approved by the Food and Drug Administration (FDA) for the treatment of AGA, but its efficacy remains poor in some patients.

Summary: Compared to finasteride, oral dutasteride has better efficacy and similar tolerability, and most adverse events are mild and reversible, making it an effective option for AGA, but its sexual adverse events and potential psychiatric risks still need to be concerned.

Effect and mechanism of coexistence of microplastics on arsenate adsorption capacity in water.

Arsenic pollution control technology in water was important to ensure environmental health and quality safety of agricultural products. Therefore, the adsorption performance of three adsorbents for chitosan, sepiolite, and Zeolitic Imidazolate Framework-8 (ZIF-8) were investigated in arsenate contaminated water. The results revealed that the adsorption capacity of ZIF-8 was higher than that of chitosan and sepiolite.

Causal effects of genetically determined metabolites on androgenetic alopecia: A two-sample Mendelian randomization analysis.

Given its increasing incidence and onset during adolescence, AGA significantly impacts both the physical and psychological well-being of affected individuals. Emerging evidence suggests a pivotal role of metabolites in AGA.

Isolation, identification and transcriptome analysis of triadimefon-degrading strain Enterobacter hormaechei TY18.

Triadimefon, a type of triazole systemic fungicide, has been extensively used to control various fungal diseases. However, triadimefon could lead to severe environmental pollution, and even threatens human health. To eliminate triadimefon residues, a triadimefon-degrading bacterial strain TY18 was isolated from a long-term polluted site and was identified as Enterobacter hormaechei.

Expert consensus on perioperative integrated skincare for noninvasive energy-based device aesthetic procedures in clinical practice in China.

Background: Noninvasive energy-based device (NI-EBD) aesthetic procedures has recently gained widespread usage for treating various skin conditions, enhancing skin texture and performing rejuvenation-related procedures. However, practically all NI-EBD procedures result in variable degrees of damage to the skin barrier, inducing pathological and physiological processes such as oxidative stress and inflammation, and only a small percentage of individuals possess the innate ability to restore it.

Objective: To introduce the concept of integrated skincare and establish standardized operational procedures for perioperative integrated skincare, and furnish a theoretical basis for clinical diagnosis and treatment performed by professional medical aestheticians.

The role of telomerase in hair growth and relevant disorders: A review.

Background: Hair diseases may present with hair loss, hirsutism, hair melanin abnormalities and other manifestations. Hair follicles are known as mini-organs that undergo periodic remodeling, and their constant regeneration in vivo reflects interesting anti-aging functions. Telomerase prevents cellular senescence by maintaining telomere length, but its excessive proliferation in cancer cells may also induce cancer.

Physiological and transcriptomic analyses reveal that phytohormone pathways and glutathione metabolism are involved in the arsenite toxicity response in tomatoes.

The main forms of inorganic arsenic (As) in soil are arsenate [As(V)] and arsenite [As(III)]. Both forms inhibit plant growth. Here, we investigate the effects of As(III) toxicity on the growth of tomatoes by integrating physiological and transcriptomic analyses.

Efficacy of hemoporfin-mediated photodynamic therapy in treating Sturge-Weber syndrome associated port-wine stains: A retrospective study.

Background Sturge-Weber syndrome (SWS) is a rare condition associated with a GNAQ gene mutation, which affects neural crest cells. A pulsed dye laser (PDL) is a first-line therapy for SWS, but its outcomes are worse than those in patients with port-wine stains (PWS). Photodynamic therapy (PDT) is a promising therapeutic option for PWS.

A randomized, double-blind, placebo-controlled phase II study to evaluate the efficacy and safety of ivarmacitinib (SHR0302) in adult patients with moderate-to-severe alopecia areata.

Background: Alopecia areata (AA) is a CD8+ T cell-mediated autoimmune disease characterized by nonscarring hair loss. Ivarmacitinib, which is a selective oral Janus kinase 1 inhibitor, may interrupt certain cytokine signaling implicated in the pathogenesis of AA.

Objective: To evaluate the efficacy and safety of ivarmacitinib in adult patients with AA who have ≥25% scalp hair loss.

Objective: To conduct a systematic review evaluating the efficacy and safety of topical and oral spironolactone in AGA treatment.

1α,25(OH)D(VD3) promotes Raddeanin A-induced anti-proliferative effects on HeLa cell apoptosis and autophagy through negative regulation of HPV18E6-E7/PD-L1/VDR axis.

Raddeanin A (RA) has indicated suppressive effects on various human tumor cells, and insufficient vitamin D was associated with human papillomavirus (HPV) persistence and gynecological tumors. However, combined effects of RA and vitamin D on HPV-positive cells remain elusive. Herein, we aimed to investigate the combined effects of RA and 1ɑ,25(OH)D (VD3) on cellular viability and modulation of HPV18E6/E7, programmed cell death 1 ligand (PD-L1) and vitamin D receptor (VDR) expression in HeLa cells .

Transcription factor FOXC1 positively regulates SFRP1 expression in androgenetic alopecia.

Androgenetic alopecia (AGA) is the most common type of hair loss dysfunction. Secreted frizzled related protein 1 (SFRP1) is found to be associated with hair loss, but its role in AGA and the regulation mechanism of its transcription level is unclear. The aim of our study is to explore the expression of SFRP1 in AGA samples and its transcriptional mechanism.

The JAK2/STAT3 pathway inhibitor, AG490, suppresses the abnormal behavior of keloid fibroblasts in vitro.

AG490 is a selective inhibitor of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. The present study examined its effects on the abnormal behavior of human keloid fibroblasts (HKFs) and evaluated its potential use in the treatment of keloids. Human normal fibroblasts (HNFs) and HKFs were treated with increasing concentrations of AG490.

Volatile composition and classification of flower aroma types and identification, polymorphisms, and alternative splicing of their monoterpene synthase genes.

Lily is a well-known ornamental plant with a diversity of fragrant types. Basic information on lily floral scent compounds has been obtained for only a few accessions, and little is known about aroma types, the terpene synthase genes that may play roles in the production of key volatiles, or the range of monoterpenes that these genes produce. In this study, 41 cultivars were analyzed for volatile emissions, and a total of 46 individual volatile compounds were identified, 16 for the first time in lilies.
