20 / 1000+ resultsresearch Rickets With Alopecia: An Inborn Error of Vitamin D Metabolism
This report describes two sisters with rickets and alopecia unresponsive to high doses of vitamin D2, where oral phosphorus supplements led to significant clinical improvement.
research Extraskeletal Actions of Vitamin D
This review examines the impact of vitamin D signaling in extraskeletal tissues and notes that expected benefits from animal and cell studies have not been consistently replicated in human clinical trials.
research The Effect of Vitamin D on the Hormonal Profile of Women with Polycystic Ovarian Syndrome: A Systematic Review and Meta-Analysis
This study analyzed 19 articles and found that vitamin D significantly improved the hormonal profile in women with PCOS, with greater effects observed after 8-week interventions compared to 12-week ones.
research Mutations in the Vitamin D Receptor and Hereditary Vitamin D-Resistant Rickets
This abstract reviews hereditary vitamin D-resistant rickets, a rare genetic condition causing severe early childhood rickets, and reports no new results; effective treatment typically requires high doses of calcium to address hypocalcemia and secondary hyperparathyroidism.
research Characterization of Type II Rickets Model Rats to Reveal Functions of Vitamin D and Vitamin D Receptor
In this study involving genetically modified rats, researchers observed that specific mutations in the vitamin D receptor affect calcium levels and bone formation, emphasizing the receptor's role in maintaining healthy bone density and its importance in regulating hair cycle and skin health.
research Cutaneous Features of Myotonic Dystrophy Types 1 and 2: Implications of Premature Aging and Vitamin D Homeostasis
This study found that patients with myotonic dystrophy types 1 and 2 often exhibit skin abnormalities, which correlate with genotype severity and serum vitamin D levels, and suggest premature aging.
research Serum Vitamin D Level and Disease Severity of Alopecia Areata: A Meta-Regression Analysis
This study found no significant correlation between vitamin D levels and disease severity in alopecia areata patients, highlighting the need for further research on vitamin D supplementation's effects.
research An Analytical Study of Serum Ferritin, Vitamin D, and Thyroid Function in Females with Diffuse Hair Loss
This study observed that low serum ferritin and vitamin D levels may contribute to diffuse hair loss in women.
research Deficient and/or Insufficient Serum 25 Hydroxy Vitamin D in Patients with Alopecia Areata: Is It a Fact or Fiction?
This study found that patients with alopecia areata had significantly lower serum 25(OH)D levels, which may be associated with increased disease severity.
research Prevention by Vitamin D2 in Combination with Milk Protein of Hair Loss Caused by Drugs
research Protective Effect of Lactalbumin-Bound Vitamin D2 on Hair Epilation Caused by Medicinal Drugs
research Serum Ferritin and Vitamin D in Female Hair Loss: Do They Play a Role?
This study found that low serum ferritin and vitamin D2 levels are associated with hair loss in females with chronic telogen effluvium and female pattern hair loss, suggesting potential benefits of screening and supplementation.
research A Non-Invasive Hair Test to Determine Vitamin D3 Levels
This study suggests that analyzing hair samples with a liquid chromatography-mass spectrometric assay may offer a reliable method to measure average quarterly vitamin D levels, potentially complementing blood tests.
research Role of Vitamin D Supplementation in the Management of Cutaneous Sarcoidosis
In this study, researchers highlighted that in sarcoidosis, macrophages in granulomas can produce vitamin D, potentially leading to calcium imbalances, where vitamin D supplementation may cause hypercalcemia, necessitating careful laboratory assessment before supplementation.
research Recent Advances in Electrospun Nanofibers for Wound Healing
This review examines recent advancements in electrospun nanofibers for wound healing applications, but reports no new experimental results, highlighting their potential in sutures, dressings, and skin regeneration.
research Increased DHT Levels in Androgenic Alopecia Selected to Protect Men from Prostate Cancer
This article discusses the hypothesis that mechanisms driving androgenic alopecia may reduce the risk and proliferation of prostate cancer by increasing prostaglandin D2 levels but presents no new clinical findings.
research 702 dsRNA Induces Ectopic KRT9 Expression via WNT/β-Catenin-Mediated Signaling
This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.
research Disruption of the Hedgehog Signaling Pathway Contributes to Hair Follicle Cycling Deficiency in VDR Knockout Mice
This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.
research Complementary and Alternative Treatments for Alopecia: A Comprehensive Review
This review examines complementary and alternative medicine for alopecia and finds limited support from robust clinical trials, highlighting the need for standardized studies to evaluate efficacy and safety.
research L-Cystine-Containing Hair-Growth Formulation Supports Protection, Viability, and Proliferation of Keratinocytes
This study found that a combination of oral compounds improved metabolic activity, cell viability, and proliferation in hair follicular keratinocytes, with L-cystine playing a key role in protection against oxidative stress.
