D‐amino acid oxidase as a chemogenetic tool for spatiotemporally controlled hydrogen peroxide production: The oxygen connection

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose D‐amino acid oxidase (DAO) has been developed as a chemogenetic tool, to precisely manipulate redox levels in tissues and cells by generating H2O2 in the presence of D‐amino acids. The enzyme's significant oxygen consumption during H2O2 production may influence cellular oxygen levels.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the risk of food poisoning due to the presence of biogenic amines in meals made from chicken meat consumed by children under 3 years of age

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Biogenic amines are low molecular weight organic bases that come from the enzymatic decarboxylation of amino acids. They are present in many types of food, with the highest concentrations usually found in fish and their derived products, as well as in beverages and fermented foods of plant, meat and dairy origin.

Wideband DOA estimation for SOBFN

IET Radar, Sonar & Navigation, 2017
This study considers the problem of wideband direction of arrival (DOA) estimation for spatial optical beam‐forming network (SOBFN). Since its system configuration is different from that of the traditional microwave beam‐forming networks, the authors first establish the observation model of SOBFN when multiple broadband signals are received.

Snow‐Covered Insights From Above and Below: High‐Frequency Measurement of Nitrogen Dioxide From Space and Ground

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite provides hourly air quality measurements over North America. This study evaluates TEMPO NO2 ${\text{NO}}_{2}$ observations over snow‐covered surfaces, highlighting its ability to capture sharp spatial and temporal gradients in NO2 ${\text{NO}}_{2}$ vertical column densities ...
