This review discusses major advances in understanding inherited hair diseases through genetic research and reports no new clinical results; the authors emphasize the potential for new preventive and therapeutic tools.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

This study suggests that down-regulation of vasculature-related genes in dermal papilla cells from balding scalps might contribute to the development of androgenetic alopecia.

This study found multipotent progenitors in sweat ducts that become unipotent after sweat gland development, highlighting distinct regenerative capabilities in adult glandular skin stem cell populations.

Four genetic risk spots found for hair loss, with WNT signaling involved and a link to curly hair.

This study found that NIH hairless mice exhibit abnormalities in hair growth and immune-related pathways, with Pik3r1 and Pik3r3 identified as key genes for further investigation.

In this study, aleglitazar and its metabolite M6 were evaluated for safety in non-clinical settings, revealing organ-targeting effects common to PPAR agonists but no significant tumor increase in rat carcinogenicity studies, supporting progression to Phase 3 clinical trials.

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.

In this study, researchers found that ligand homodimerization controls the receptor binding specificity of the FGF9 subfamily, preventing off-target activation of FGFR "b" isoforms.

This study found that preserving hair follicles at 4℃ using Ringer's solution during FUE Megasession hair transplantation surgery significantly improves cell survival rates and supports optimal hair growth, demonstrating clinical feasibility for longer procedures.

In this study, researchers found that patients with alopecia areata who had nail involvement or a history of autoimmune disease showed significantly higher red cell distribution width levels.

The researchers observed that in cichlid fishes with different dental structures, tooth replacement accelerated more than three times following tooth extraction, alongside distinct changes in gene expression and cellular interactions over one week, providing insights into tooth regeneration mechanisms in vertebrates.

This study found that miR-432 inhibits KRT83 expression, revealing potential molecular mechanisms for the formation of curly fleece in Tan sheep and suggesting implications for understanding curly hair formation in humans.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This study found that the Dun camouflage color in horses is due to TBX3 expression, which causes uneven pigment deposition, whereas non-dun coat colors result from regulatory mutations affecting TBX3 expression.

This study identified nine pathogenic variants in the PADI3 gene and variants in the S100A3 and TCHH genes in patients with central centrifugal cicatricial alopecia, suggesting a broader genetic basis for the disease and potential targets for genetic testing and therapies.

In this study, the isotopic fractionation between tissues and diets of captive Japanese macaques was quantified, particularly noting hair's response to diet changes in controlled conditions, but these findings underscore the complexity of reconstructing long-term dietary history.

This study identified morphotype-specific gene expression patterns in feathers, enhancing understanding of the molecular and cellular processes involved in feather development and diversification.

This study found that the medicinal formula YH0618 may reduce toxicity from the chemotherapy drug doxorubicin, improving side effects like hair loss and organ damage, while maintaining its anti-cancer effects.

This article contains the late-breaking abstracts from the 39th Annual Conference of the American Society for Laser Medicine and Surgery and does not present new research results.

This study found that dyed chitin nanofibers maintain color and mechanical properties when reinforcing resins, allowing color addition and strength improvement while retaining transparency.

This review discusses the application of trichoscopy in diagnosing various hair and scalp diseases and reports no new clinical results; the authors emphasize its role as a non-invasive diagnostic tool.

In a 24-week randomized trial, this study found that the RAMACAP laser helmet significantly increased hair density and diameter in androgenetic alopecia patients compared to a sham device, although limitations included a small sample size and potential issues with the control used.

This review discusses the role of various genetic regulators in maintaining human mesenchymal stem cell stemness and highlights strategies for ex-vivo expansion, but reports no new clinical findings.

This study found that extracts of mesenchymal stem cells (MSC-extract) and their protein components (MSC-protein) enhanced the proliferation and migration of periodontal ligament cells and induced significant periodontal tissue regeneration, showing potential as a new cell-free treatment for periodontal disease.

In this study, deuruxolitinib and baricitinib showed promising efficacy in treating alopecia areata, but effectiveness varied with dosage and further trials are needed to confirm these results.

This study found that COVID-19 infection disrupts spermatogenesis, alters testicular cell populations, and may impact male fertility by causing long-term changes in testicular function and reduced sperm quality, as observed even in patients who have recovered from the acute phase of the infection.

This study found that finasteride treatment in male rats altered steroid hormone homeostasis and caused kidney damage, suggesting potential risks for patients with renal dysfunction on androgen or antiandrogen therapy.

This study established the R-7 dermal papilla cell line, which retained essential characteristics of primary cells without undergoing malignant transformation, suggesting its potential for future hair research.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.
