This study identified three new mutations in the VDR ligand-binding domain that may cause dysfunction, and noted that oral calcium and calcidol treatment was effective, but only one patient experienced hair growth.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This study highlights the complex role of the vitamin D receptor in skin processes, where its disruption, along with calcium and co-regulator imbalances, could contribute to skin cancer development by altering skin differentiation and hair follicle cycling.

This study found significant variability in the production and use of platelet-rich plasma and related products in Brazil, highlighting the need for regulatory measures to ensure safety.

This study found that SMR-2 and SMR-6, analogs of retinoic acid and retinol, were approximately 100 times more toxic than retinoic acid in mice, inducing hypervitaminosis A and affecting various organs and tissues.

This review outlines current European legislation and manufacturing standards for platelet-rich plasma (PRP) products and provides guidance for clinicians implementing autologous PRP treatments, without reporting new clinical results.

This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.

This study identified a novel V26M mutation in the vitamin D receptor as the cause of hereditary vitamin D resistant rickets in a patient, characterized by severe rickets and an unusual pattern of alopecia.

This chapter reviews current and future strategies for identifying ligands and functions of orphan G protein-coupled receptors, but it reports no new experimental results.

This study analyzed safety data for semaglutide, liraglutide, and tirzepatide from the EudraVigilance database, identifying potential safety signals not listed in current SmPCs, such as optic ischemic neuropathy and pancreatitis, underscoring the importance of ongoing pharmacovigilance.

This study found that a collaborative care model in rheumatoid arthritis clinics improved nb-DMARD dose optimization, adherence to monitoring guidelines, and detection of related adverse drug events compared to standard care.

This study resulted in a draft version of the Patient‐Reported Impact of Dermatological Diseases measure, PRIDD, which includes 27 items refined from patient consensus and is now undergoing psychometric testing.

This study found that mice lacking the vitamin D receptor (VDR) developed skin tumors more rapidly than those with normal VDR activity, regardless of 1,25-dihydroxyvitamin D(3) presence.

In this study, pregnenolone was found to dose-dependently reduce L-DOPA-induced dyskinesias in a rat model of Parkinson's disease, suggesting its potential as a therapeutic target for these dyskinesias.

This review examines how vitamin D and its receptor regulate various skin functions, such as cell differentiation and immunity, and explores the mechanisms involved, without reporting new clinical results.

In laboratory and artificial skin model experiments, this study found that plant-derived PDRN from Korean ginseng effectively promoted skin cell regeneration and strengthened the skin barrier, suggesting a sustainable alternative to animal-derived PDRN.

This study developed a new, simple, and economical RP-TLC method with densitometry that is suitable for routine analysis of finasteride in tablet dosage form, meeting analytical validation criteria.

This study developed a new measurement procedure using isotope dilution-liquid chromatography-tandem mass spectrometry for accurate quantification of DHEAS in human serum or plasma, demonstrating high selectivity, sensitivity, and low measurement uncertainty, making it suitable for routine standardization and clinical evaluation.

This study reports that PDRN, commonly used for wound healing, may also have anti-melanogenesis and potential skin whitening effects in both experimental models and clinical settings.

This article outlines the potential for upregulating the vitamin D receptor in treating hair disorders, emphasizing the need for further studies to evaluate vitamin D's role in the hair cycle.

Using PDRN injections and RF treatments improved revision nose surgery results without major side effects.

This review categorizes 59 modifications of the Dermatology Life Quality Index across multiple studies, highlighting the need for further validation of these customized health-related quality of life tools in dermatology.

PDRN may help with female hair loss, but more research is needed.

In this study, TCDD administered to male rats down-regulated EGF receptor in liver plasma membranes and increased protein kinase activity, suggesting EGF receptor–mediated toxicological effects.

This study demonstrated that the glycolytic inhibitor 2-deoxy-D-glucose enhances antiseizure effects by potentiating extrasynaptic tonic GABAergic inhibition through neurosteroidogenesis in hippocampal slices.

This review compares DNA-derived biopolymers, PN and PDRN, in dermatology, emphasizing their distinct molecular characteristics and roles, and reports no new clinical results.

This review describes how liver and kidney diseases and diabetes may affect ethyl glucuronide levels in hair, impacting forensic and clinical interpretations, but reports no new experimental results.

This study found that basal cell carcinomas show strong expression of vitamin D receptors at both mRNA and protein levels, suggesting a potential role in tumor growth regulation.

This study found that ion-paired solutions significantly improved the skin penetration of risedronate in hairless mice compared to risedronate alone.

The conclusion is that improved training and oversight for cosmetic procedures are recommended to better protect patients.
