Isolation and Identification of Erysipelothrix sp. in Hybrid Grouper (Epinephelus fuscoguttatus × E. lanceolatus) in Taiwan

Journal of Fish Diseases, EarlyView.
ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.

Pharmacological Modulation of Nrf2 Signaling Regulates Oxidative Stress, Inflammation, and Alveolar Bone Loss in Experimental Periodontitis

Journal of Periodontal Research, EarlyView.
Pharmacological activation of Nrf2 attenuated alveolar bone loss and protected periodontal tissues by reducing inflammation and oxidative stress, preserving collagen organization, and favoring bone homeostasis. Reversal of these effects by Nrf2 inhibition further supports Nrf2 signaling as a promising therapeutic target in periodontitis.

Light‐Controlled Modulation of 15‐Lipoxygenase‐1 Regulates Intestinal Inflammatory Signaling

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
The developed target‐guided strategy enables the rational design of diazo‐based photoswitchable inhibitors of 15‐lipoxygenase‐1. Distinct molecular architectures program opposite light‐dependent activity, allowing on‐demand control of enzyme inhibition.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Anion–π interactions influence pKa values

Beilstein Journal of Organic Chemistry, 2011
Five 8-(4-R-phenyl)-1-naphthol derivatives were prepared by PdCl2-catalysed electrophilic aromatic substitution. The pKa' values for these 1,8-disubstituted arene naphthols have been measured in acetonitrile/water (R = NO2, 8.42; R = Cl, 8.52; R = H, 8 ...
