A 7-year-old girl was diagnosed with Netherton's Syndrome, shown by skin and hair symptoms.

This study found that mild skin injuries in rats, especially those dosed with dihydrotachysterol, lead to mineral deposits in hair follicle tissue within 6-12 hours, as confirmed by chemical and X-ray diffraction analyses.

This study reported intra-familial transmission of Arthroderma benhamiae among Canadian porcupines in a Japanese zoo, with genetic sequences previously undocumented in Japan or the GenBank database.

This study suggests that using stable isotope analysis on various tissues can effectively reconstruct individual life histories, providing insights into both the individual and broader population from the Romano-Christian period in Egypt.

This study observed wide clinical diversity among five patients with the same VDR gene mutation causing vitamin D-dependent rickets type II, suggesting involvement of a nuclear accessory factor and a nongenomic action of the vitamin.

This study found that individuals with heterozygous truncation-type variants in the *DSP* gene exhibit lower skin temperature and higher transepidermal water loss, with specific microscopic skin changes and pseudomonilethrix.

This source offers an in-depth review of Methandrostenolone, examining its pharmacology, performance-enhancing effects, potential health risks, and legal status in various countries, while emphasizing the scientific evidence surrounding its use and misuse.

The medicine Diane is effective in treating hair loss, severe acne, and excessive hair growth.

This study found that the main structural proteins of tree frog toe pads, which aid in their adhesive properties, are alpha keratins that have evolutionary origins in early tetrapods.

This study found that dutasteride affected spinal bone formation in curdlan-treated SKG mice, while DHT treatment reduced osteoblast differentiation in vitro, suggesting that DHT inhibition might unexpectedly increase spinal ankylosis progression in ankylosing spondylitis patients.

This study found that the androgen precursors DHEA and androstenedione stimulated androgen-sensitive parameters in the sebaceous glands of the skin in castrated male hamsters.

This study suggests that dermal adipocytes play a significant role in skin aging, particularly through the process of adipocyte-myofibroblast transition, highlighting them as potential targets to combat aging in chronically photo-damaged skin.

This study found that nanodiamonds of various sizes can penetrate different layers of murine skin in vitro, reaching hair follicle niches, and may be suitable for multimodal imaging applications.

This study found that 2MbisP increases epidermal thickening more rapidly than atRA in rhino mice, while both compounds similarly reduce utricle size.

This study found that two novel nonsteroidal derivatives inhibited specific enzymes in vitro and in vivo, leading to dihydrotestosterone accumulation in androgen-dependent glands, suggesting potential therapeutic use for mood improvement in the elderly.

In this report, a 19-year-old Japanese man experienced severe and prolonged urticarial reactions following treatment with diphenylcyclopropenone for alopecia universalis, emphasizing the need for caution with potent sensitizers.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

This study observed that among !Kung San males, adult androgen levels, particularly DHT, were negatively associated with indicators of fluctuating and directional asymmetry, suggesting a link to phenotype quality.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

In this case report, a 16-year-old female with Netherton syndrome, a rare genetic disorder, exhibited symptoms such as skin issues, hair abnormalities, and elevated serum IgE levels. The diagnosis was supported by skin biopsy, and treatment included topical therapies, NB-UVB, and infliximab.

In this study using Xenopus laevis embryos, reduced levels of the desmosomal protein desmoplakin led to defects in epidermal and cardiac structures, suggesting its crucial role in tissue integrity.

In this study, researchers found that alpha-keratin homologs similar to those in mammalian hair are present in the claws of the lizard Anolis carolinensis, suggesting a structural role during claw formation.

This study suggests that the C-terminal of AHF is crucial for its binding to keratin bundles and modulating the keratin meshwork in hair follicles.

This study demonstrates that the trichohyalin gene is located at chromosomal region 1q21, where several other genes related to epidermal differentiation also map.

This study found that the cytoplasmic dynein component Dynlt3 is essential for effective melanosome transport and transfer in mouse melanocytes, linking melanosome positioning and acidity to the Wnt/β-catenin signaling pathway.

This article discusses a hypothesis on the development and evolution of scales, hairs, and feathers from fish to amniotes, based on regions of dermo-epidermal interactions in skin, but reports no new findings.

This study describes a newly recognized skin reaction associated with dasatinib, nilotinib, and ponatinib, marked by a lichenoid exanthem with severe pruritus that may necessitate discontinuation of therapy.

This study examined the evolutionary and functional homology of steroid 5α-reductase and DET2 proteins, identifying protists as a common ancestor, and discovered a new subclass DET2-like in plants, potentially involved in polyprenol reduction.

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.
