This study found that C57BL/6 mice and Sprague–Dawley rats show distinct distributions of eccrine sweat glands and hair follicles in their volar skin, suggesting these models should be selected according to research focus on skin appendages.

This study found that 17β-estradiol was the most powerful hormone for inducing APE1/Ref-1 secretion in cultured vascular endothelial cells, with secretion occurring through exosomes dependent on estrogen receptors and intracellular calcium.

In this study, female patients undergoing hormone replacement therapy showed improvements in frontal hairline appearance and increased hair plucking strength, suggesting positive effects of estradiol on hair growth while excluding age-related factors.

This study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

This study identified pathogenic or likely pathogenic gene variants in 70.1% of Russian families affected by hypohidrotic ectodermal dysplasia, expanding knowledge of causative mutations.

HA-iMSC-EVs can improve skin aging by boosting cell growth and restoring collagen and elastin.

The researchers reported that the rat Hershberger assay reliably detected endocrine-disrupting effects of finasteride, procymidone, and 17α-methyltestosterone, validating the assay's sensitivity for identifying hormonal activity.

This study found that Erdr1 expression was significantly reduced in the skin of patients with hair loss disorders, particularly alopecia areata, suggesting it may serve as a novel biomarker.

This study found that Puerariae Radix ethanol extracts increased the proliferation of human hair dermal papilla cells via ERK and Akt phosphorylation, suggesting potential benefits for alopecia treatment.

This study found that a topical henna formulation may improve symptoms like itching, burning, and redness in patients with recessive dystrophic epidermolysis bullosa, but larger controlled studies are needed.

This study found that knocking out the Hars2 gene in mouse cochlear hair cells led to mitochondrial dysfunction and ROS stress, resulting in progressive hearing loss and differential effects on inner and outer hair cells.

This review discusses the diverse functions and therapeutic potential of ectopic olfactory receptors throughout the body, emphasizing their roles in various cellular processes and potential in cancer detection and therapy, but reports no new clinical results.

This study found that SHJH hr mice, with a Hairless gene mutation, exhibit accelerated skin aging potentially due to poor antioxidative protection, highlighting the Hr gene's role in skin aging.

This review discusses how dehydroepiandrosterone (DHEA) may exert its biological effects through multiple receptors and reports no new clinical results.

Estetrol (E4) can help hair grow longer by extending its growth phase.

This study identified a novel homozygous EDNRA variant linked to Oro-Oto-Cardiac Syndrome and showed that EDNRA signaling is essential for normal craniofacial and cardiovascular development.

This study found that ethanolic leaves extract of Hibiscus rosa-sinensis L. exhibited strong antioxidant activity and enhanced wound healing properties in mice, showing reasonable safety in toxicological evaluations without severe alterations.

This article describes protocols for isolating and expanding human epidermal neural crest stem cells and discusses their potential for cell-based therapies in regenerative medicine, but reports no new clinical results.

This study reported that Ell-Cranell® alpha 0.025% solution significantly increased hair counts and diameter in Korean women with female pattern hair loss over an 8-month period, showing both efficacy and safety.

This study proposes a new test for genome-wide association studies that incorporates Hardy-Weinberg equilibrium into SNP analysis, demonstrating improved power and interpretability over traditional methods, as evidenced by simulations and an alopecia study dataset.

This study found that 17β-estradiol inhibited RANTES production in human keratinocytes by suppressing nuclear factor κB activity, suggesting a potential mechanism for 17β-estradiol's modulation of psoriasis-related inflammation.

This report describes two cases of Rapp–Hodgkin ectodermal dysplasia where refractory scalp erosions improved significantly with potent topical steroids; it also suggests a potential link between these scalp conditions and erosive pustular dermatosis of the scalp in elderly patients.

This review discusses the roles of Eph receptors and ephrins in various diseases, highlighting their potential as therapeutic targets, but it presents no new research findings.

This study found that 17beta-estradiol enhanced allergy responses in certain age groups of female mice and inhibited thymus involution and regeneration after contact hypersensitivity.

This study found that extracellular vesicles derived from cardiosphere-derived cells classified as potent were effective in reducing cardiac hypertrophy and improving systemic health markers in rats with induced cardiac aging.

In this case report, veterinarians observed a 16-year-old mare with symptoms including chronic weight loss, pruritus, muscle atrophy, and lameness, which gradually progressed to neurological issues despite initial treatment.

Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

In this retrospective cohort study, researchers reported that 11.5% of patients with DRESS developed significant long-term autoimmune or renal sequelae, with age influencing the type of sequelae observed.

This study found that finasteride-induced DHT deficiency altered estrogen receptor expression in the epididymis, potentially destabilizing its function.

This study found that epidermolysis bullosa simplex keratinocytes had impaired mitochondrial activity and more dispersed mitochondrial distribution compared to normal human keratinocytes.
