This study found significant species differences in the enzyme activity and inhibitor affinities of prostatic 5α-reductases from rats, dogs, and humans, with variable potencies for different 3-oxo-4-azasteroid inhibitors across species.

This study found that the JMJD3/NF-κB-Notch1 pathway plays a crucial role in regulating keratinocyte migration and skin wound healing, with Notch1 affecting key genes involved in cell migration.

In this study, decellularized human amniotic membrane was found to promote wound healing and reduce scar formation in rats with full-thickness skin defects, compared to traditional clinical treatments.

This study found that the ARL15 gene affects adipocyte differentiation and adiponectin secretion, and suggests that ARL15 haploinsufficiency may predispose individuals to lipodystrophy.

This discussion explores advances in intravital imaging for visualizing stem cells, highlighting key discoveries and potential future developments; it reports no new experimental results.

In this study, focal atrichia was associated with late-onset female pattern hair loss, providing a clinical clue to its diagnosis, particularly separating it from other hair disorders.

In this study, researchers developed a dissolvable microneedle patch combining HA-TEMPO and Portulaca oleracea L.-derived nanoparticles, which effectively reduced oxidative stress and inflammation in an atopic dermatitis model while restoring immune balance, suggesting a promising treatment strategy.

Understanding skin structure and development helps diagnose and treat skin disorders.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This review discusses the potential of stem cell secretome in regenerative medicine and suggests that its paracrine effects, rather than direct cell replacement, may drive therapeutic benefits.

The authors concluded that chronic telogen effluvium in middle-aged women presents distinct clinical and histological features that differ from androgenetic alopecia and acute telogen effluvium.

This article discusses the hair follicle's regenerative cycles and the molecular mechanisms influencing them, emphasizing the need for therapeutic targeting of the "hair cycle clock" to manage hair growth disorders, without reporting new research findings.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This study concluded that dermoscopy enhances the diagnostic capability for cicatricial alopecia beyond clinical inspection and identified novel dermoscopic features such as blue-grey dots.

This article reviews the development and formulation of shampoos, emphasizing their dual role as cosmetic and medicinal products, but presents no new experimental findings.

This review examines the roles of macrophages and Langerhans cells in skin homeostasis and suggests that understanding these functions can aid in developing therapies for skin and hair regeneration, but it reports no new research findings.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

This study found that the creation of hair follicle lumens in mice is driven by the outward migration of keratin 79-positive cells, suggesting a novel mechanism for generating hollow cores in hair follicles.

This review discusses the molecular basis and clinical implications of primary generalized glucocorticoid resistance and hypersensitivity, attributing them to mutations in the human glucocorticoid receptor gene, and reports no new clinical findings.

This study found that macrophages are crucial for skin regeneration during tissue expansion, as their depletion in rats led to inhibited skin growth and reduced secretion of key growth factors.

This study suggests that chronic telogen effluvium may be due to a reduction in the variance of anagen duration, resulting in recurrent hair shedding with minimal long-term hair volume loss.

In this study, CD4+CD25+FoxP3+ Regulatory T cells were found to reduce TGF-b1 induced lung fibrosis and fibrocyte accumulation in mice, partly by suppressing fibroblast growth factor 9.

This study found that fibromodulin significantly reduces scar formation and boosts scar strength in rodent and porcine models, suggesting potential for FMOD-based therapies in cutaneous wound repair.

In this study, researchers found that alkylating chemotherapy causes hair follicle stem cells to lose their regenerative ability by initially triggering proliferation followed by apoptosis, leading to permanent regeneration loss.

This study found that T-regulatory cells, specifically the FOXP3 CD39 subset, were significantly reduced in both circulation and hair follicles of alopecia areata patients compared to healthy subjects, suggesting potential therapeutic targets.

Continuous light exposure in rats leads to PCOS-like symptoms and suggests sleep habits might affect the disorder's development.

This paper proposes a systematic approach to evaluating scalp itch using the SCALLP acronym and highlights the importance of classifying cases based on the presence of dermatological lesions and hair loss, but it reports no new clinical findings.

In this controlled study, a pulsed electrical field treatment significantly increased hair regrowth compared to baseline and the control group over 36 weeks, without observed side effects.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

This review discusses gender identity disorder in Japan, highlighting the high prevalence and challenges in accessing appropriate treatment, and calls for wider understanding among medical professionals.
