This summary discusses the role of endocrinology and nutrition in skin health, highlighting the importance of a balanced approach to UV exposure, nutrition, and potential benefits of probiotics without reporting new research findings.

In this study, researchers found a correlation between x-ray patterns and the element composition of human hair, with certain metal roles in the hair matrix considered.

This review examines how biochemical and biophysical induction factors influence cell fate in tissue engineering and reports no new experimental results.

This study developed a method to quantify hormones in skin secretions and found that hormonal composition varies by sex and anatomical site.

This study found that the concentrations of major inorganic elements in human scalp hair increase with age up to 25 years, and calcium and magnesium concentrations are significantly associated with sex in individuals over 20.

Biologicals are increasingly used in medicine and cosmetics, especially for skin and hair treatments, but more research is needed.

This record provides supplementary materials for a theoretical model suggesting that animal-based diets may support hair follicle stability through various biological mechanisms, including regenerative peptides and anti-glycation protection.

This study found that an 11-month-old Japanese infant developed biotin deficiency while on a Japanese amino acid formula without biotin, which was resolved with biotin supplementation.

This study found significant correlations for copper and zinc levels between hair and plasma in Pomeranian and Labrador dogs, but no significant correlation for iron.

This study developed and validated a method using hair samples to simultaneously detect bisphenols and parabens, enabling the quantification of these endocrine disruptors in a hospital population’s hair.

This review suggests that brassinosteroids may have similar biological activities in both plants and other organisms, prompting further exploration of steroid regulation mechanisms across different life forms.

In this study, researchers developed WS Biotin, a new water-soluble form of biotin, and found that it significantly improves water solubility compared to free biotin and enhances hair-related keratin expression, gene activity for hair growth in vitro, while also reducing melanin content in skin cells.

In this study, the researchers observed that biotin administration in biotin-deficient children with alopecia eliminated certain membrane proteins from their blood, suggesting that biotin might regulate these proteins' expression.

This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.

This article reviews how biopolymers are utilized in cosmetics, highlighting their biodegradable and non-toxic properties, recent structural developments, novel applications, and safety considerations in the formulation of skin, hair, and oral care products.

This study found that lead accumulated in the hair shafts of individuals exposed to mining environments, while iron, copper, and zinc levels remained stable, highlighting the significance of SRXRF micro-analysis for environmental health research.

This study observed that hair levels of chromium, manganese, and copper were lower in diabetics compared to controls, while iron levels were higher.

This study identified that the enzyme CYP2B12 is skin-specific and likely plays a role in the metabolism of arachidonic acid, a key component in lipid signaling within sebaceous glands.

This study found that multimetal starvation by the immune protein calprotectin triggers unique regulatory responses in Pseudomonas aeruginosa, beyond those seen with individual metal shortages.

This study examined hair mineral and free amino acid components in various diseases and found that when using effect size analysis, specific components related to diabetes and other conditions were identified, suggesting their potential as novel health indicators.

This review evaluates the scientific literature on silicon supplements, noting that orthosilicic acid shows higher bioavailability, but emphasizes the need for further clinical studies on safety and efficacy.

This study presents a method using liquid chromatography tandem mass spectrometry to quantify biotin in plasma and serum, and explores how high biotin intake can interfere with diagnostic immunoassays that utilize biotin-streptavidin technology, potentially leading to misdiagnosis of endocrine disorders.

This review explores the diverse physiological roles of the vitamin D endocrine system, discussing current research on receptor structure, transcription details, murine models, and alternative receptors, but reports no new findings.

This study observed light flashes and repulsion effects in a single-slide preparation of human hair with a special solution, suggesting potential electromagnetic field emissions from the hair.

This study developed a novel mineralization strategy using metal-polyphenol coordination for dynamic control of nano-scale processes, enhancing hydrogels that support wound healing with antibacterial and angiogenesis-promoting properties.

This study found that consumption of dietary supplements and sports nutrition may lead to therapeutic and cosmetic improvements, benefiting skin, hair, and nails while potentially enhancing athletic performance.

The study found that applying Bifidobacterium-fermented soy milk extract to human skin significantly reduced the decline in skin elasticity, suggesting its potential as a cosmetic ingredient to prevent skin aging.
