Advanced Science, EarlyView.Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Preparative thin-layer and column chromatography of prostaglandins
Journal of Lipid Research, 1969 Analytical and preparative chromatographic methods for monounsaturated prostaglandins are described. The systems were developed specifically for separation of the various hydroxy epimers of prostaglandin E1 and F1 but also offer superior separations for ...

Advanced Science, EarlyView.Glioblastoma (GBM) is an aggressive brain cancer that often recurs and resists chemotherapy. This study found that a chemical called PGE2 causes surrounding brain cells (neurons) to become over‐excited, which makes GBM cells resistant to treatment. Researchers developed a new drug, “Compound 11,” which can cross into the brain and effectively block ...

An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations
Angewandte Chemie, EarlyView.This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...

Advanced Science, EarlyView.The immunocompetent Intestine‐on‐a‐Chip (IoC) is developed using melt electrowritten (MEW) half‐pipes. Intestinal epithelial cell (IEC) culture is optimized in the MEW‐based IoC, followed by co‐culture with monocyte‐derived dendritic cells (moDCs) and T cells in 3D hydrogels.

Angewandte Chemie, EarlyView.Cyclopentyl and cyclobutyl 1,3‐bis‐boronic esters have been prepared from benzylic carbamates with excellent regio‐, diastereo‐ and enantioselectivity. The method enables the asymmetric cycloalkanes bearing bis‐boronic esters which can be manipulated independently. Abstract Saturated carbocycles are common motifs in natural products and pharmaceuticals,
