This article provides an overview of how dermoscopy can aid in the noninvasive diagnosis of various general dermatological disorders, grouped by clinical presentation, but reports no new clinical results.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This paper reviews the complex pathophysiology of polycystic ovary syndrome, exploring how hormonal and metabolic disturbances contribute to its symptoms and related health risks, but it presents no new findings.

This article discusses the long-standing use and safety of opioids in anaesthesia, noting that respiratory depression is a manageable side effect due to the availability of opioid antagonists.

This article discusses the potential benefits of safflower in traditional Persian medicine for various conditions and highlights the need for comprehensive phytochemical research, without reporting new clinical results.

In this study, patients with generalized pustular psoriasis were classified into subgroups to better understand the disease's variability and assist in treatment selection, highlighting the role of localized infections in triggering flares.

This study estimates that young adults have about 230,000 tactile afferent fibers innervating their skin, with density varying by region and decreasing with age.

This article reviews the scientific exploration of Ayurvedic medicinal plants and discusses their modern applications, such as a drug developed from Commiphora wightti for lipid disorders, without reporting new clinical findings.

This review discusses the effects of estrogen on skin and reports no new clinical results; it highlights estrogen's potential benefits on skin thickness, collagen quality, and hair follicle life cycle.

This review explores finasteride's effects on neuroactive steroid levels and their potential influence on disorders like depression and alcohol withdrawal but reports no new clinical findings.

This study found that trichoscopy criteria can distinguish female androgenic alopecia from chronic telogen effluvium, with specific features achieving 98% diagnostic specificity.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

This study found that hair follicles in both mice and humans may serve as an important site for melatonin synthesis and signaling, potentially influencing hair cycle regulation by modulating keratinocyte apoptosis.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This review examines the epidemiology, pathophysiology, diagnosis, and management strategies for non-classic congenital hyperplasia due to 21-hydroxylase deficiency, and provides evidence-based recommendations for its treatment and genetic counseling.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

In this study, PRP injections increased hair count and reduced hair loss in patients with androgenic alopecia not responding to minoxidil and finasteride, with high patient satisfaction reported.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This article discusses the histologic features of psoriasis, including psoriasiform epidermal hyperplasia and neutrophilic involvement, but reports no new clinical findings.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.
