This study found that the LH response to nafarelin effectively distinguished gonadotropin deficiency from constitutional delay of puberty, performing comparably to the sleep test and offering certain advantages.

This study assessed the potential for Ocean Thermal Energy Conversion power in Fiji, finding higher power output and efficiency during summer due to greater temperature differences between surface and deep sea waters.

This piece discusses the conditions of three children with disparate symptoms—suggesting silent aspiration, exogenous androgen exposure, and long QT syndrome—and emphasizes comprehensive assessment and history for correct diagnosis and management.

In this study, rabbit esophageal epithelial cells were found to produce K4 and K13 keratins in suprabasal cells, forming disulfide-crosslinked dimers that may support the physical stability of the esophageal lining.

In this study, 755-nm alexandrite laser treatment significantly reduced acne keloidalis nuchae lesions in male patients, improving quality of life and showing low recurrence rates, with temporary hair loss as a reversible complication.

This study found that the methylation level at CpG III site 4 of the KRT17 gene promoter significantly influences wool production in Angora rabbits, suggesting its potential as an epigenetic marker for breeding high wool yield.

This study found that a graphene-barium titanate nanosystem can accelerate wound healing by killing bacteria and promoting fibroblast proliferation, demonstrating effectiveness in both Gram-negative and Gram-positive bacteria-infected wounds in mice.

This study found that a high-energy shock wave can increase osteogenic activities in human mesenchymal cells, offering insights into potential therapeutic targets for trauma-induced heterotopic ossification.

This study found that overexpression and knockdown of DKK4 influence genes involved in hair follicle growth and development in Angora rabbits and identified specific SNPs in DKK4 associated with wool quality, notably showing that the TT/GG haplotype combination relates to higher fibre diameters.

This research analyzed two ancient mammoth hair strands and reported distinct structural and elemental differences, including calcium, iron, and copper deposits, which vary with age and origin.

In this case review, researchers describe a 17-year-old transgender male experiencing clitoromegaly, hirsutism, and oligomenorrhea, investigating conditions like PCOS and non-prescription testosterone use for gender affirmation, and highlighting the importance of gender-affirming care to improve mental health outcomes.

In this study, the authors found that the shoulder guard hair of captive sika deer most accurately reflects dietary information during winter coat growth, useful for analyzing wild deer hair samples.

This study concluded that S. hexaphylla extract may improve androgenetic alopecia by reducing 5α-reductase and androgen receptor levels, inhibiting apoptosis, and promoting keratinocyte proliferation in experimental models.

This case study reports that a 16-year-old girl with hirsutism and menstrual irregularities was diagnosed with a benign steroid cell ovarian tumor, after high testosterone levels indicated a potential androgen-secreting source.

This case study describes an 88-year-old postmenopausal woman diagnosed with Sertoli-Leydig cell tumor, a rare ovarian cancer, highlighting the importance of checking hormone levels in similar unexpected cases.

This study suggests that inaudible sound at 30 kHz may promote hair growth and inhibit hair loss signals in human dermal papilla cells, indicating potential as a new treatment for androgenic alopecia.

This review paper highlights that titanium dioxide nanoparticles (TiO2 NPs), due to their biological properties like antioxidant, anti-inflammatory, and antimicrobial effects, show promise in accelerating wound healing and enhancing tissue regeneration when used in scaffolds and dressings.

Among men with androgenetic alopecia, this study found that taking 5 mg of KX-826 twice daily significantly increased hair count compared to a placebo, with the treatment being well-tolerated and no serious adverse effects reported.

In this study, hibiscus leaf extract hair tonic at 10% concentration showed better hair growth promotion activity compared to minoxidil 2% in a rabbit model, although it caused eye irritation.

In this study, RNA integrity in horse hair follicles stored at various conditions in RNAlater® was maintained, showing that storing them at cool or room temperature for up to a week does not compromise RNA quality or concentration.

This study found that diagnosing nonclassic congenital adrenal hyperplasia in women based solely on serum 17OHP measurements can lead to false positives, suggesting the need for urinary steroid profiles and genetic testing for confirmation.

In this study, researchers identified two distinct homozygous mutations in the KRT85 gene among consanguineous Pakistani families with pure hair and nail ectodermal dysplasia, highlighting variations in severity and potential impacts on the K85 protein function.

This case report describes a 7.5-year-old girl with precocious puberty displaying significant secondary sexual development and advanced bone age, treated monthly with Leuprolide.

This study found no significant differences in hair growth between two formulas of hair tonic from meniran extract, one with a menthol enhancer, despite variations in hair length and weight measurements.

This study found that GTx-024 significantly increased total lean body mass and improved physical function in healthy elderly men and postmenopausal women, suggesting potential use for muscle wasting conditions.

This study observed that noncertified Kohl used in Iranian cities contained heavy metals within WHO suggested limits, but highlighted concerns due to high levels in some samples.

In this study, a water-soluble nail strengthener containing Pistacia lentiscus and hyaluronic acid significantly improved the appearance and firmness of brittle nails in both in vitro and clinical settings.

This report describes an 11-year-old girl with peripilar keratin casts, a condition often underdiagnosed and mistaken for nits, highlighting the usefulness of keratolytic treatments in management.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.
