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 ...

What anabolic–androgenic steroids reveal about the limits of current harm reduction models
Abstract Background Harm reduction has largely been shaped by responses to psychoactive drug use where the most urgent harms are acute. These models focus on overdose, blood‐borne viruses, and rapid‐onset toxicity related harms. When applied wholesale to anabolic–androgenic steroids (AAS), they obscure the distinctive pharmacology, consumer typologies,

Skin adverse events (AEs) frequently accompany all types of anticancer treatments. This publication discusses how recent international guidance on best‐practices use of dermocosmetics can be adapted to the North Asia region (China, Hong Kong, Japan, Republic of Korea, and Taiwan).

This retrospective study of patients with small, node‐negative HER2+ breast cancer found favorable 5‐year invasive disease‐free survival rates—93% for pT1mic/a disease and 100% for pT1b disease. Trastuzumab was administered to 66% of patients and was associated with larger tumor size and higher histologic grade.

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension
Background and Purpose The contribution of obesity to pulmonary arterial hypertension (PAH) pathophysiology remains poorly understood. Adipose tissue synthesises estrogens via cytochrome P450 (CYP) 19A1 (aromatase), whereas circulating estrogens are metabolised in the lung by CYP1A1.

Critical role of the mast cell/tryptase/PAR2 axis in anastrozole‐induced pain
Abstract Background and Purpose Anastrozole, an aromatase inhibitor, is used to treat postmenopausal women with hormone receptor‐positive breast cancer, but also induces musculoskeletal pain and can lead to therapeutic regimen suspension. Aromatase inhibitors promote the release of pro‐inflammatory substances from sensitised nerve fibres, which might ...

Opioids in breast cancer: Between analgesia and modulation of tumour progression
Preclinical investigations consistently demonstrate that activation of μ‐opioid receptors and δ‐opioid receptors promote proliferation, migration, angiogenesis, epithelial‐mesenchymal transition, acquisition of cancer stem cell phenotypes, and chemoresistance.

Estrogens are hormones that play an important role in the digestive tract, including in men. Letrozole is an inhibitor of cytochrome P450 aromatase, an enzyme converting androgens to estrogens.
