This ex vivo study reported that melatonin significantly improved certain aging biomarkers in aged human skin, including reduced mTORC1 activity, increased fibrillin-1, and enhanced collagen and elastic fiber organization, though other key biomarkers remained unchanged.

This study suggests that DNA-neutralizing agents like DNAse I and Resveratrol-Cu might reduce chemotherapy-induced toxicity, although this conclusion is based on a small animal study and needs more research.

In this study, certain cysteine residues in Romney sheep wool fibers were labeled more often during stretching tests, particularly under wet conditions, suggesting variability in their disulfide bond contributions to fiber mechanics depending on hydration.

This review discusses the role of oestrogens in stimulating linear bone growth and pubertal changes in both boys and girls, highlighting their influence on the growth hormone-insulin-like growth factor axis; it reports no new clinical results.

This study found that single-dose x-ray irradiation in rat calvaria skin led to morphological changes in collagen fibers, disorganization, and a temporary absence of sebaceous glands and hair follicles.

In this study, topical application of Korean maritime pine bark extract at 2% concentration significantly promoted hair growth in mice, suggesting its potential use for hair loss prevention or treatment.

Eye lens capsules are the best for growing human skin cells.

This study successfully optimized a culture strategy for dermal papilla cells and established an immortalized cell strain, iDP6, which is suitable for research and application.

This study found that 40.42% of undergraduate medical students aged under 25 had early canities, with grade I being the most common.

This study suggests that type I 5-alpha reductase may also play a role in hair growth, with dutasteride potentially being more potent than finasteride in modulating key hair growth gene expressions.

In laboratory research, investigators found that apoptotic vesicles from interleukin-10-treated fibroblasts promote wound healing and reduce fibrotic scarring by enhancing mitochondrial function, modulating collagen composition, and inhibiting the Hedgehog signalling pathway, offering potential for regenerative medicine applications.

This study found that topically applied melatonin exerts significant anti-aging effects on human scalp skin ex vivo, including increased SIRT1 expression and reduced mTORC1 pathway activity.

In preclinical studies, topical CUR61414 reduced Hh signaling and shrank BCCs in mice, but this study found no clinical efficacy in human superficial or nodular BCCs.

This study found that repeated use of a protein hair conditioner, followed by hot air and gamma irradiation, may lower serum collagen I and increase heat shock protein concentrations in rats, suggesting potential cumulative risks.

This study developed an in vitro artificial hair germ model using dermal papilla cells and skin keratinocytes to explore early stages of hair follicle regeneration.

This study found that molecular differences in paracrine factors between balding and non-balding hair follicles may enhance understanding of androgen action in hair disorders and potentially inform better treatments.

This study used proteomics to identify various proteins in human hair, which may help develop novel biomarkers for hair health, disease, and aging.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.

This study found that procyanidin B-2 may promote hair growth by reducing expression and inhibiting translocation of PKC isozymes in murine hair epithelial cells.

This study found that β-sitosterol, a brain-penetrable phytosterol, reduced melanoma cell growth and brain metastasis formation by interfering with mitochondrial respiration, suggesting its potential as an adjuvant therapy to BRAF inhibitors for patients with melanoma brain metastases.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.

In this study, collagen I decellularized scaffolds enhanced the growth and melanotic properties of hair follicle melanocytes, suggesting their potential as effective carriers for transplantation in vitiligo treatment.

This article discusses the immune privilege in hair follicles and suggests that restoring its collapse might be an effective strategy for treating alopecia areata and cicatricial alopecia, but it reports no new clinical results.

This research suggests that innate lymphoid cells type 1 (ILC1) may contribute to the development of alopecia areata, alongside CD8+ T cells, by disrupting hair follicle immune privilege and promoting features of the disease.

In this study, trichoscopy was found to be an effective noninvasive tool for diagnosing female pattern hair loss at early stages, potentially eliminating the need for scalp biopsies.

In this study, researchers developed a computational method called iEdgePathDDA that prioritizes anticancer drug candidates by analyzing changes in gene interactions, demonstrating superior performance compared to existing methods across colorectal, breast, and lung cancer datasets.

This study identified previously unknown phase I and phase II metabolites of finasteride in human bile and urine using a specialized bile collection technique and advanced mass spectrometry analysis.

This paper discusses the role of steroid sulfatase in hormone-dependent tumors and highlights the development of potent inhibitors, noting the commencement of a phase I trial for one inhibitor in postmenopausal breast cancer patients.

This study found that keratin K80, structurally similar to hair keratins, is broadly expressed in various epithelial tissues and is involved in intermediate filament formation with multiple type I partners.

This study introduces an extended approach to the Bonferroni procedure that accounts for correlations among endpoints, aiming to improve test power while maintaining strong control of the family-wise type I error rate in clinical trials.
