This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This study found that elastic fibre arrangements in the skin of domesticated mammals vary with hair density, with densely-haired species having horizontal fibres and sparsely-haired ones exhibiting a sponge-like system.

Researchers observed that dutasteride and finasteride caused structural changes in the penises of both control and hypertensive rats, with dutasteride having a more pronounced effect on the corpus cavernosum.

This study found that Sonic Hedgehog protein treatment enhanced the sprouting and regeneration of pelvic ganglia and cavernous nerves after injury, with localization of delivery affecting outcomes.

This study observed that both dutasteride and finasteride affected penile morphology in normotensive and hypertensive rats, with more pronounced changes in hypertensive animals, especially when treated with dutasteride.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

In this mouse study, researchers reported that sequential monopolar-bipolar radiofrequency irradiation significantly improved skin quality by increasing collagen density, elastin fiber expression, and fibroblast differentiation more than monopolar RF treatment alone.

This article reviews applications of optical coherence tomography techniques in medicine, including for diagnosing androgenic alopecia and monitoring blood coagulation, but provides no new clinical results.

This article reviews the potential of inhalation therapy to restore pulmonary elastin fibers in COPD patients and highlights the need for studies to test its feasibility; it reports no new research findings.

This review explores the complex interrelationships among different properties of natural hair fibers and underscores the need for a holistic taxonomy to improve data interpretation across disciplines, but it reports no new experimental results.

In this study, minoxidil treatment in aged mice increased elastin expression and improved aortic structure and function, suggesting its potential for arterial remodeling in aging.

Minoxidil treatment in mice preserved the integrity of elastic lamellae and improved arterial biomechanical properties, especially in females, suggesting it could be an anti-arterial aging agent potentially suitable for female-targeted therapies.

The authors concluded that diazoxide reduces undesirable side effects compared to minoxidil while increasing elastic fiber content and decreasing cell number in the aorta, suggesting potential suitability for treating vascular conditions with low arterial elastin and hypertension.

This review discusses the significance of elastic tissue staining in dermatopathology, particularly for diagnosing primary elastic tissue disorders and other skin conditions, but reports no new clinical results.

In this study, researchers linked hair composition and mechanical properties to perceived hair quality, suggesting that hair quality may be genetically determined.

This study found that combining CelluTome system and RCM is a safe and effective protocol for evaluating wound healing responses in patients with epidermolysis bullosa.

This study found that photoexposure significantly increased the gene expression of altered elastin, MMP12, and LOX, as well as the protein expression of tropoelastin and fibrillin-1, in skin models.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

Lichen planopilaris is a rare, chronic condition causing hair loss, mainly in middle-aged women, and early treatment is important to prevent permanent baldness.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This abstract provides no research results, focusing instead on navigation and subscription details for JAMA Dermatology content access.

This study reports that a new protocol using Angio PRP improved wound healing in mice by enhancing key healing processes and regulating inflammation, suggesting potential for clinical advancements.

This chapter reviews common cosmetic dermatology techniques but presents no new findings; it discusses treatments like emollients and laser therapy for conditions like photoaged skin and acne scarring.

This study observed that in Assam Hill Goats, the primary hair follicles had larger diameters and more structural associations compared to secondary follicles, especially in ruminant-age groups.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

The document concludes that correct diagnosis of alopecia types is crucial, scalp biopsies are important, and more research is needed.

This study observed that mast cells and increased collagen and elastic fibers in the scalp may contribute to male pattern hair loss, but additional research is needed for further understanding.

This review discusses the use of derma rollers for cosmetic purposes and their potential in transdermal drug delivery by summarizing evidence on their design, efficacy, safety, and concerns from preclinical and clinical reports.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.

This study found that tianeptine may suppress the transition to catagen, promoting hair growth in a stress-induced alopecia areata mouse model.
