This study developed a double-wavelength laser scanning microphotometer to measure hair shaft and follicle absorbance, improving spatial resolution and reducing light scattering effects in vitro.

Allergic contact dermatitis may promote hair growth by activating hair follicle stem cells.

In this study, cyclic ADP-ribose (cADPR) treatment in human hair follicle dermal papilla cells was associated with increased intracellular calcium retention and activated anagen-related signaling without causing significant cytotoxicity, indicating its potential impact on hair growth processes.

In this case report, a 9-year-old boy with diffuse alopecia areata showed improvement with topical diphencyprone immunotherapy, suggesting it as a safe and effective treatment option in pediatric cases of alopecia areata resistant to other therapies.

In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

In this study, a novel VDR gene mutation was identified in a child with HVDRR, and the researchers observed that high-dose intravenous calcium therapy led to significant and sustained improvement in rickets symptoms.

This case study reports on a rare form of vitamin D resistant rickets in a 37-year-old male, highlighting the condition's clinical features and the necessity for a thorough understanding of calcium and vitamin D metabolism in the diagnosis and management of metabolic bone diseases.

Hair transplantation can lead to rare scalp complications, requiring careful follow-up and treatment.

This review discusses methods to better identify unsafe donor areas in patients with diffuse unpatterned alopecia, emphasizing non-surgical management when specific diagnostic criteria are met, but reports no new clinical results.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

This case study reported on a 3-year-old child with vitamin D-dependent rickets type II treated in the Gaza Strip, whose condition deteriorated despite vitamin D and calcium treatments, leading to recurrent chest infections, respiratory failure, and eventual death.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

This study found that dengue virus infection caused inflammation and cell death in human hair-follicle dermal papilla cells, which may contribute to increased hair shedding observed during the epidemic in Taiwan.

This study introduced a multifunctional DNA hydrogel dressing that may enhance wound healing by promoting tissue regeneration, nerve repair, and immune response in diabetic infectious wounds.

This study found that multiple eccrine duct dilation is highly specific for diagnosing cicatricial alopecia and may indicate scarring processes, aiding in accurate differential diagnosis from noncicatricial alopecias.

This study found that nano-sized lipid particles improved the skin accumulation and retention of dexamethasone compared to a base cream, suggesting potential benefits for inflammatory skin disease treatment.

This study analyzed trichoscopic features of discoid lupus erythematosus on the scalp in skin of color and found distinct patterns based on clinical morphology.

This study found that dimethylpabamidopropyl laurdimonium tosylate, a quaternary ammonium surfactant, adsorbs onto human scalp hair with kinetic and isotherm behaviors fitting specific models, changing hair fiber wettability from hydrophobic to hydrophilic.

This study found that using a bicomponent reduction system with TGA and DTDG for hair straightening limited hair damage by forming only thiol groups, while a TGA-only system formed more damaging mixed disulfide groups.

This case study reported significant clinical improvement in a 26-year-old male with dissecting cellulitis of the scalp after treatment with upadacitinib, suggesting that JAK inhibitors may be a promising option for refractory cases, where standard treatments have limited success.

In this study, researchers observed that Vdr-knockout mice experience hair cycle arrest during the catagen stage, leading to alopecia, with persistent epithelial strands forming in the hair follicles, indicating Vitamin D receptor's role in regulating hair follicle regression and regeneration.

This article reviews the early establishment of dermatology as a specialty in the U.S. and documents the initial descriptive errors in understanding Darier's disease, offering no new clinical data.

This study found that upregulation of NFIC may enhance proliferation and osteogenic/cementogenic differentiation in rat dental follicle cells.

In this case study, a 19-month-old infant with palmoplantar keratoderma and nail dystrophy was found to have a desmoplakin gene mutation, leading to cardiomyopathy by age 7, illustrating diagnostic challenges and the potential link between skin, dental, and cardiac anomalies.

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 research re-analyzed single-cell gene expression data from a mouse model, confirming that certain genes involved in the EDA-EDAR and WNT pathways are crucial for skin appendage development, suggesting that their restoration may mitigate the effects of hypohidrotic ectodermal dysplasia in children.

In this study, finasteride was found to significantly reduce DHT levels and affect spermatogenic markers in rats, while DA-9401 co-treatment indicated potential ameliorative effects.

Dermoscopy helped diagnose discoid lupus erythematosus in two patients without needing skin biopsies.

This study found that the DNN-DTIs prediction model achieved high accuracy in predicting drug-target interactions, suggesting its potential application in drug repositioning and the discovery of new uses for existing drugs.

This review discusses current treatments for discoid lupus erythematosus and highlights anifrolumab as a promising option for difficult cases, but no new clinical results are reported.
