Copper is an essential trace element, yet concerns regarding its toxic potential have gained increasing attention, particularly with regard to nanoparticulate forms of copper oxides. Both CuO and Cu 2 O are currently authorised in the EU for use in agriculture, biocides, and animal nutrition, but regulatory clarity regarding their nanoforms remains limited. This comprehensive review—combining narrative, bibliometric, and syste...

Human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) cultured in the presence of retinoic acid were proposed as a model for human atrium. Since in the human heart positive inotropic effects of serotonin (5-HT) are restricted to the atrium, we investigated whether the presence of 5-HT responses may distinguish between hiPSC-atrial and ventricular CM. Nonfiltered retinoic acid (1 µM) was used to induce an atrial...

Vascular endothelial growth factor A (VEGF-A) is a key signalling protein that stimulates blood vessel development and repair. Its tight control is essential for organ development and tissue homeostasis. However, the complex regulatory network for balanced bioavailability of VEGF-A is not fully understood. Here, we assessed the role of the glycocalyx component polysialic acid (polySia) for kidney development and its potential...

The invasive ascomycete Hymenoscyphus fraxineus is the causative agent for ash dieback on the European species Fraxinus excelsior and Fraxinus angustifolia, and there is concern that it is going to replace the native, closely related and nonpathogenic Hymenoscyphus albidus . Fungal management in forests is limited, and alternative approaches for control are needed. Within the scope of the project “FraxForFuture”, several strat...

Dissolved and particulate organic carbon (DOC, POC) and nitrogen (DON, PON) constitute essential nutrient and energy sources to heterotrophic microbes in aquatic systems. Especially in the shallow coastal ocean, the concentrations are highly variable on short timescales, and cycling is heavily affected by different sources and environmental drivers. We analyzed surface water organic carbon and nitrogen concentrations determine...
