This study found that after application of a testosterone cream containing 17α-methyltestosterone and testosterone propionate, these compounds could be detected in dried blood spots up to 97 hours post-application, potentially leading to sample contamination during fingertip puncture.

This minireview discusses a proposed model of the vitamin D receptor that explains how 1alpha,25(OH)2D3 can mediate both genomic and rapid responses through different ligand shapes and cellular locations, without presenting new research findings.

This study found that the vitamin D receptor, but not its ligand, regulates genes involved in hair cycle progression, suggesting a role in integrating hormone signaling pathways for hair and epidermal functions.

This study shows that measuring 17-hydroxyprogesterone concentrations in scalp hair may be a useful noninvasive tool for monitoring treatment in adults with congenital adrenal hyperplasia.

HPLC may detect prediabetes and diabetes earlier than Immunoturbidimetry because it shows higher A1c levels.

This study observes the expression of mRNA for androgen receptor, 5α‐reductase, and 17β‐hydroxysteroid dehydrogenase in human dermal papilla cells.

This study found an increased risk of asthma and allergic rhinitis in individuals with hidradenitis suppurativa.

This study indicates that the normal human prostate is not a major contributor to circulating blood DHT concentrations in androgen-deficient patients receiving testosterone replacement therapy.

This study developed a novel method to simultaneously measure finasteride, dutasteride, and related biomarkers in serum, finding that both drugs lowered DHT levels while increasing substrate concentrations.

This study found that reduced plasma DIAPH1 levels were associated with polycystic ovary syndrome, suggesting DIAPH1 as a potential predictive factor for the condition.

This study found that while DP concentrations in dust were higher in male dormitories, DP in hair was higher in females, suggesting differing metabolism between genders and that hair DP mainly originates internally.

This study found that after topical application in rats, 1,24-dihydroxyvitamin D3 absorbed through both the stratum corneum and hair follicles, with about 30% excreted via the faeces.

This study found that women with androgenetic alopecia had significantly higher mean plasma levels of DHEA-S and total testosterone compared to normal females, despite most individuals in both groups being within normal hormonal ranges.

This study observed that the molecular structure of keratins in hair fibres' discrete transition zone differs in breast cancer patients, with altered lipid ester absorption bands reverting post-cancer removal.

This review discusses the role of RDH12 in vision, its structural and functional aspects, and related disease mechanisms, but reports no new clinical results; it aims to support therapy development for inherited retinal dystrophies.

In this study, diode laser treatment showed greater efficacy in reducing facial hair and increasing satisfaction among hirsutism patients with normal levels of DHEAS and DHT, compared to those with deranged levels, although some benefits were observed across both groups.

The researchers reported that DHT may reduce the inflammatory responses induced by C. acnes in androgen-sensitive human sebocyte cells, suggesting a potential link between androgens and infection in sebaceous disorders.

This review outlines the complexities of understanding DHT biosynthesis and metabolism in the human prostate and reports no new findings, emphasizing the need for further research into the pathways involved.

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

In this study, researchers observed that red and red-orange LED light therapy stimulates nitric oxide production and decreases dihydrotestosterone synthesis in cell models, suggesting a potential mechanism for using light therapy to treat androgenetic alopecia.

This study found that LEDs at specific wavelengths may improve antifungal performance and promote hair growth by activating scalp cells without inducing inflammation compared to a non-irradiated group.

This study demonstrates that human epidermal stem cells can adapt to environmental temperature changes through mTOR signaling, and prolonged inhibition of mTORC1 supports stem cell maintenance, which may be vital for regenerative medicine.

This study found that the small signaling peptide RALF22 plays a key role in root hair growth response to volatile compounds emitted by Penicillium aurantiogriseum through ethylene, auxin, and photosynthesis signaling in Arabidopsis.

Vitamin D3 affects cell differentiation in specific skin areas.

In this study, the authors identified the DHRS9 SNP rs72623193 as most significantly associated with response to dutasteride in treating male pattern hair loss, with additional variants potentially contributing.

This study suggests that DHT may have a less potent effect on the prostate compared to testosterone while maintaining safety and similar effects on erythropoiesis and lipids.

This study found that an increased calcium/magnesium ratio in hair and lower chromium concentration were associated with higher insulin resistance in Korean adult males.

In this study, testosterone and dehydroepiandrosterone in children's hair were strongly correlated, supporting hair as a potential method for measuring these hormones.

Dihydrotestosterone (DHT) mainly affects nearby cells, doesn't significantly change prostate hormonal environment or cancer risk, and doesn't play a main role in causing hair loss or acne. More research is needed on its effects on heart health, sexual function, and bone health.
