This study found that an 8-week supplementation with specific probiotic strains improved hormonal markers and oxidative stress while decreasing inflammation in women with PCOS, although clinical symptoms like acne and hirsutism showed no significant improvement compared to the placebo group.

This study showed that keratinase pretreatment effectively reduces the time for enzymatic unhairing in bovine hides by opening channels for faster penetration, which shortens the process by over 50% and enhances leather quality.

In this study, peptide nanofiber gels RG and RJ significantly accelerated the healing of deep second-degree burn wounds in vivo, with greater wound closure rates and enhanced tissue regeneration compared to controls, attributed to increased angiogenesis and reduced systemic inflammation.

This report describes siblings with vitamin D-dependent rickets type 2, characterized by growth retardation, alopecia totalis, and low 25(OH)D3 levels, highlighting its autosomal recessive pattern and distinction from other rickets types.

In this randomized, placebo-controlled study, the tested cosmetic ingredient containing Trifolium pratense flower extract and a biomimetic peptide increased anagen hair and improved the anagen/telogen ratio over four months in individuals with recessing hair.

This study identified a novel genetic mutation, c.429delC in the hairless gene, associated with atrichia with papular lesions in two Pakistani families.

This study found that Cerasus serrulata extracts, when obtained through specific methods, demonstrate significant antioxidative and antibacterial properties, as well as potential anti-alopecia effects in a mouse model, potentially making them useful supplements for these purposes.

This study found that polymorphisms in KRTAP13.1, KRTAP27-1, and KRTAP24-1 were significantly associated with fiber diameter in Jiangnan cashmere goats, which may aid future breeding and conservation efforts.

This study identified proteins that are differentially expressed in balding versus non-balding dermal papilla cells, potentially aiding the understanding and treatment of androgenetic alopecia.

This study uncovered that bimatoprost, a prostaglandin analog, promotes hair growth by activating hair follicle progenitor cells through two pathways: the PTGFR-MAPK signaling axis and an unexpected IGF1R-PCAD-AKT signaling axis, suggesting new potential targets for treating hair disorders.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

This study introduces a new multimodal imaging technology to visualize and quantify cell dynamics in natural skin over long durations, demonstrated in GFP bone marrow-transplanted mice, to study dynamic skin regeneration.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

This study identified two evolutionarily conserved ultra-high-sulfur keratin proteins in human and sheep hair follicles, which are specifically expressed in the hair cuticle during the late stages of fiber development.

This study identified two single-nucleotide polymorphisms and three haplotypes in the KRTAP7-1 gene across yak, taurine, and zebu cattle, with the BOVIN-KRTAP7-1*A haplotype most prevalent.

This study identified two key pentapeptide quasi-repeats in human keratin-associated proteins, which are similar to motifs found in sheep wool.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This research describes a two-step culture system for pluripotent mouse ES cells that produces hair follicle-like structures, providing a valuable model to study stem cell differentiation in vitro.

This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

This study reports that the symptoms and immunological findings in two children with diverse autoimmune-like conditions were ultimately attributed to lysinuric protein intolerance, confirmed by genetic analysis in one child.

In this study, a "frequent profile" of hair proteins was observed in 180 of 182 individuals, showing consistent electrophoretic bands characteristic of keratins, with rare deviations in two samples.

This laboratory study found that PI extract, along with its metabolites Ang and Mac, inhibited cell proliferation and protein expression linked to pathways involved in BPH, suggesting potential for therapeutic use, although the Ang-Mac combination showed no significant effect on apoptosis through the p53 pathway.

In this study, researchers identified a novel genetic variant in the NR3C1 gene in a mother and her son that predicts a truncated protein, leading to glucocorticoid resistance syndrome with mild hyperandrogenic features, although no clear genotype-phenotype correlation has been established.

In this study, no significant differences in cellular stress response or growth capabilities were found between FUE and FUT hair restoration techniques.

This study identified two novel genes, pmg-1 and pmg-2, expressed in various skin and gland tissues and potentially involved in the differentiation of epithelial cells in epidermal appendages.

This study found that two pre-Hispanic mummies from the Andean coast had well-preserved hair with significant amounts of heavy metals like iron, lead, bromide, and occasionally arsenic, revealing their historical context.

This study identified two novel genetic variants associated with Alzheimer's disease in APOE ε4 non-carriers, revealing insights into the disease's underlying regulatory mechanisms.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

In this study, permanent waving treatments, especially those using lotion B and repeated procedures, were found to significantly damage hair protein content and physical properties.
