This study demonstrated that intact adult human dermal papillae can induce hair growth when implanted into mouse hair follicles, highlighting their potential for advancing hair follicle biology and therapeutic approaches.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This study reports the successful generation of inducible pluripotent stem cells from mesenchymal stem cells derived from human hair follicles, marking a novel method of reprogramming these cells.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study reports that men with androgenic alopecia experience altered neuroactive steroid levels associated with persistent depression symptoms even after stopping finasteride treatment.

This review discusses the potential benefits and risks of selenium in cancer prevention and treatment, emphasizing that while selenium may offer advantages for tumor patients, further research is needed due to mixed findings regarding diabetes risk.

This article discusses the foundational concepts of nanotechnology and its contributions to dermatology and medicine, but does not present new research findings.

This article reviews hair analysis for drug detection and its applications in various fields, but reports no new research findings, emphasizing the need to consider the method's complexities and potential pitfalls.

This study found that nanostructured lipid carriers with more soybean phosphatidylcholine provided better skin retention and follicular targeting for diphencyprone compared to other formulations and controls.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This review examines the main absorption sites and influencing factors for orally administered drugs, highlighting variables such as solubility and gastrointestinal conditions that affect drug absorption in the small intestine and the development of effective drug delivery systems.

This study found that repeated microneedle stimulation in mice promoted hair growth and increased the expression of hair-growth-related genes, suggesting potential therapeutic uses for alopecia.

This study found low- to very low-quality evidence suggesting that several pharmacological treatments, including alpha blockers and antibiotics, may reduce prostatitis symptoms without significantly increasing adverse events in the short term, although more rigorous trials are needed.

In this study, mutations in the CDH3 gene were identified as the cause of hypotrichosis with juvenile macular dystrophy, and the researchers observed substantial phenotypic variability among affected individuals.

This study found that the hairless gene in mice has a more extensive role in development than previously thought, as indicated by its expression in various tissues and associated abnormalities in hr/hr mutants.

This review discusses the potential applications and challenges of small molecules in regenerative medicine, but it reports no new research findings.

This meta-analysis found that people with alopecia have an increased risk of coronary heart disease and several cardiovascular risk factors compared to those without alopecia.

This review discusses the symptoms, diagnosis, and current treatment recommendations for polycystic ovary syndrome, noting that many women may remain undiagnosed and at risk for complications.

This study suggests that variations in PCOS phenotypes observed across different ethnic groups may be due to a genetic gradient resulting from historical human migrations and genetic drift.

This review discusses idiopathic hirsutism, potential underlying mechanisms, and various therapeutic approaches without providing new clinical results, and emphasizes the need for further research on well-defined patient groups.

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.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

In this study, researchers identified two distinct homozygous mutations in the KRT85 gene among consanguineous Pakistani families with pure hair and nail ectodermal dysplasia, highlighting variations in severity and potential impacts on the K85 protein function.

This study observed that nuclear β-catenin expression in non-small-cell lung carcinomas correlates with increased proliferation and loss of key cell-cycle checkpoints, suggesting an oncogenic advantage.

This article proposes criteria to differentiate between medicalization and over-medicalization, examining the consequences and ethical considerations of misidentifying medical issues, and suggests guideline questions to help draw clearer boundaries in medicine.

Negative expectations can cause adverse effects in patients even without active treatment, and managing this nocebo effect involves better communication and patient-clinician relationships.

This review discusses the role of δ-subunit-containing GABA A receptors and neurosteroids in temporal lobe epilepsy, highlighting their plasticity and potential pharmacological implications, without reporting new clinical results.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This review describes the expanding medical uses of micropigmentation, including for vitiligo, burn scars, and nipple-areola reconstruction, and highlights safety concerns related to sterilization practices.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.
