This study demonstrated that VD3 significantly enhanced the proliferation and differentiation of epidermal stem cells in a murine skin defect model, leading to improved wound healing, potentially through activation of the PI3K signaling pathway.

This study suggests that persistent symptoms in patients with controlled functioning adenomas may indicate a coexisting PCOS diagnosis, highlighting the need for precise differentiation and timely management of these conditions.

This pilot study found that a very low-carbohydrate eating pattern, combined with supportive affect and mindful eating skills, was feasible and acceptable for weight management in young women with obesity, with 50% of participants losing at least 5% of their body weight over four months.

This report observed a case of pilomatrixoma appearing at the COVID-19 vaccination site of a 65-year-old man, aligning with previous findings that suggest a potential association between vaccination sites and this benign tumor.

This study found that applying a formulation derived from Bacopa procumbens significantly promoted hair growth, pigmentation, and follicular cycle acceleration in mice compared to minoxidil, potentially offering a new therapeutic approach for hair health.

This study observed that specific dermoscopic features, such as altered pigmentary network and yeast invasion of hair follicles, along with certain histopathological features, assist in diagnosing pityriasis versicolor.

This review discusses hair shaft disorders, noting the lack of specific treatments and recommending general care practices to prevent hair damage, with some improvement possible during puberty or with treatments like minoxidil.

This study reported that metallic-glass-coated tattoo needles reduced trauma and improved tattoo quality in pig skin experiments compared to uncoated needles.

In this case report, narrowband-UVB phototherapy successfully treated a rare instance of Graham Little-Piccardi-Lassueur syndrome, a variant of lichen planopilaris, as investigated through non-invasive imaging techniques.

Hair shaft changes may be linked to CCCA, but their role is unclear.

This study found that pigmented vellus and upright regrowing hairs are the only predictive trichoscopic markers of hair regrowth in patients with alopecia totalis and universalis.

This case report describes a 45-year-old man with a pituitary macroadenoma whose symptoms and tumor size improved significantly after one month of treatment with cabergoline.

This study found that combining oral chelated Zinc with 5% minoxidil solution improved hair density and hair shaft diameter in women with female pattern hair loss, without reported side effects.

This chapter discusses the role of hormones in regulating reproductive biology and outlines how the endocrine system, particularly the brain and pituitary gland, controls these hormonal processes.

This case study describes a rare cutaneous follicular hybrid cyst intimately associated with syringocystadenoma papilliferum, proposing a potential relationship with the infrainfundibulum based on keratin expression.

This case report describes a twenty-year-old woman misdiagnosed with a sebaceous cyst that was actually pilomatrixoma, a benign skin lesion from hair matrix cells, confirmed by histopathology after excision.

In this study, researchers reported that the Pinkie mutation in mice, affecting RXRa activity, leads to skewed Th1 development and suggests RXRa's role in Th2 differentiation, impacting immune responses.

This article explains the significance of culturing the pilosebaceous unit for studying related diseases and skin epithelial stem cells, but it reports no new findings.

This article discusses the history and understanding of Tay syndrome, recognizing it as a distinct condition related to ichthyotic erythroderma, mental retardation, and brittle hair but reports no new clinical results.

This study measured elemental content in anagen hair fibers of Caucasian people aged 10-69 and found average levels of sulfur, zinc, calcium, and chlorine, establishing a baseline for future research.

This study found that miR-27a may influence sheep hair follicle stem cell proliferation and apoptosis by targeting PIK3R3, affecting the AKT/MTOR pathway.

This study found that dihydrotestosterone treatment in female rats altered anterior pituitary gland gene expression, with significant repression of prolactin and inhibition of GnRH receptor gene expression, suggesting specific hormone production changes.

This critique suggests that the prior iconodiagnosis of Vermeer's "Girl with a Pearl Earring" suffers from confirmation bias, arguing that cultural trends, rather than medical conditions, explain the artwork's features.

In this study, researchers found that overexpression of LncRNA RP11-818O24.3 in hair follicle stem cells promotes their proliferation, self-renewal, and differentiation while inhibiting apoptosis through the FGF2-mediated PI3K/AKT signaling pathway, suggesting potential therapeutic applications for hair loss treatment.

This study found that the "pink tax" persists in topical minoxidil products, with foams marketed to women costing about 20% more than those for men, despite identical ingredients and an overall price increase since 2017.

This literature review reports that mutations in the SASH1 gene are linked to different pigmentation disorders, including dyschromatosis universalis hereditaria and lentiginosis. It further suggests SASH1's significant role in melanocyte processes and its potential as a target for developing treatments for these conditions.

This case report links sorafenib treatment in a 22-year-old man with relapsed acute myeloid leukemia to a rare instance of drug-induced pityriasis rubra pilaris-like eruption.

This study found that 830 nm LED light effectively treated post-inflammatory erythema and hyperpigmentation, while both 830 nm and 590 nm LEDs prevented post-inflammatory erythema.

This study found that inhibiting the PI3Kδ enzyme in murine models of cutaneous chronic graft-versus-host disease (cGVHD) reduced skin scores and fibrosis, prevented pathogenic lymphoid structures, and improved survival, suggesting it as a promising therapeutic approach to address the disease's hypoxic pathophysiology.

Pigs are a good model for studying human hair growth and disorders.
