Photobiology of Epidermal Melanocytes

, 2019
Detecting and responding to sunlight is a basic requirement of nearly all life forms. But how the skin, a principal organ to receive sunlight, precisely detects and responds to light remains poorly understood.

Broadening the View: Substance P and Its Metabolism in Pruritus‐Related Diseases

The Journal of Dermatology, EarlyView.
ABSTRACT Chronic pruritus is a debilitating symptom accompanying numerous inflammatory skin diseases and remains a major therapeutic challenge. Neurogenic inflammation plays a central role in its pathogenesis, with the tachykinin substance P acting as a key mediator at the interface of the nervous system, immune cells, and cutaneous tissues.

Risk of Cancer With Hormone Replacement Therapy: A Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Hormone replacement therapy (HRT) remains the cornerstone of menopausal symptom management, effectively alleviating vasomotor symptoms and genitourinary syndrome, whilst mitigating long‐term risks such as osteoporosis. However, despite an increasing body of evidence on the relative safety of HRT, earlier studies that demonstrated an increased ...

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

Integrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Low Sunscreen Awareness and Misconceptions in Skin of Colour With Acne‐Related Post‐Inflammatory Hyperpigmentation: A Cross‐Sectional Study Highlighting the Need for Targeted Education

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background/Objectives Post‐inflammatory hyperpigmentation (PIH) is a frequent sequela of acne in patients with skin of colour (SOC). While sunscreen is widely recommended for PIH prevention, little is known about real‐world sunscreen practices in this group. This study aimed to evaluate sunscreen use, barriers and factors influencing adherence

Demographic Analysis of the Sun Protective Behaviours and Skin Cancer Risk of Victorian Farmers

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Background Farmers have an elevated risk of melanoma and non‐melanoma skin cancer due to their occupational exposure to high levels of ultraviolet radiation. The sun protective behaviours of farmers are poorly understood, limiting targeted interventions to this at‐risk population.

A Case of Lentigo Maligna Presenting as Repigmentation of Hair in a Scalp That Previously Underwent Radiotherapy for Tinea Capitis

Australasian Journal of Dermatology, EarlyView.
ABSTRACT Lentigo maligna has occasionally been noted to have the capacity to invade and repigment grey hairs. We present a case of a 78‐year‐old male who presented with a patch of brown hair on the vertex of the scalp in an area of previously white hair.
