This review discusses the potential of microneedle arrays for drug delivery and in the cosmetic market, but reports no new clinical results; factors for commercial therapeutic use are explored.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This study found that all-trans and 9-cis retinoic acids increase steroid sulfatase activity in HL60 cells through mechanisms involving RARα/RXR heterodimers and multiple signaling pathways.

This study found that only minoxidil encapsulated in cationic vesicles significantly promoted hair growth in mice, likely due to its higher retention on the skin.

This study reported that a new laser scanner using 655 nm red and 808 nm infrared lasers significantly improved hair density in patients with androgenic alopecia compared to both a laser hat and no treatment, without observable adverse effects.

This study found that androgen binding in male rat livers involves specific androgen receptors, which decrease with castration and are inducible in female livers with testosterone.

In this study, researchers identified two potential urinary biomarkers, testosterone–glucuronide and 11α-hydroxyprogesterone, along with four candidate biomarkers, to help understand and diagnose polycystic ovary syndrome.

This study reported that treating wounds with a hydrogel from acellular porcine adipose tissue and adipose-derived stem cells may significantly enhance wound healing and regeneration by promoting new adipocyte formation.

This study found that the ARL15 gene affects adipocyte differentiation and adiponectin secretion, and suggests that ARL15 haploinsufficiency may predispose individuals to lipodystrophy.

This study found that testosterone and dihydrotestosterone are crucial for synaptic transmission and spine density in male hippocampal neurons, suggesting sex-specific effects of neurosteroids on brain development.

This study found that platelet-rich plasma was effective for hair regrowth in women with androgenic alopecia, though less so than minoxidil, but it was associated with improved quality of life responses.

This study found that thermoresponsive hydrogels can maintain mechanical memory in fibroblasts, enhancing wound healing compared to traditional trypsinized methods.

This review discusses the role of PIN-FORMED 2 and related signaling pathways in root hair growth regulation and reports no new experimental findings.

This study found that Rumex japonicus extract may help reduce symptoms of atopic dermatitis by inhibiting inflammatory responses in both cell cultures and a mouse model.

This study identifies a likely pathogenic homozygous missense variant in the AEBP1 gene in a patient with symptoms of classical Ehlers-Danlos syndrome, suggesting new perspectives for EDS classification and research.

This study found that acne inversa is primarily an epithelial-driven disease, with cyst-forming tendrils causing inflammation due to rupture and the release of debris, highlighting limitations of punch biopsies for analysis.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This study found that sex differences in somatostatin biosynthesis in rat hypothalamic neurons develop between postnatal day 1 and 5, influenced by the conversion of testosterone to estrogen.

This study established an androgen-responsive human organ culture model using hair follicles, demonstrating that women's intermediate facial follicles grow more hair in response to men's higher androgen levels.

This study identified a novel insertion mutation in the hairless gene that may contribute to the development of congenital atrichia with papular lesions in a Pakistani family.

This study found that Annurca apple polyphenolic extracts reprogram hair follicle metabolism in mice, enhancing mitochondrial activity and keratin production while inhibiting some metabolic pathways.

This study observed that electro-acupuncture reduced global DNA methylation and DNMT3b expression in a PCOS-like rat model, suggesting a role of hypothalamic DNA methylation in PCOS development and treatment.

In this study, adipose-derived stem cells from superficial adipose tissue showed higher regenerative potential, and more macrophages were found in superficial than deep adipose tissue, potentially influenced by skin microbiota.

In this mouse study, hair growth defects associated with the Gk5 null allele were partially alleviated by simvastatin treatment, suggesting GK5 plays a key role in skin-specific cholesterol regulation.

This chapter reviews nanotechnology in cosmetics, detailing various formulations, performance assessment methods, and evolving regulations, while discussing safety, stability, and effectiveness concerns; it reports no new experimental results.

This report describes a study of estuarine bed-sediment quality in New Jersey and New York post-Hurricane Sandy, focusing on contamination extent and potential long-term impacts, with no new findings included.

This article discusses primary cicatricial alopecias, a group of rare inflammatory scalp disorders resulting in permanent hair loss, and reports no new findings.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

Finasteride reduces inflammation and improves immune response after trauma by altering hormone levels.

This review discusses recent advances in understanding the cellular, molecular, and genetic factors contributing to lupus erythematosus and reports no new experimental findings.
