Biomimetic Bone Marrow Monocyte Membrane‐Fused Extracellular Vesicles for Targeted Therapy of Myocardial Infarction

Advanced Science, EarlyView.
This study develops a biomimetic delivery system (M‐hEV) by fusing monocyte membranes with extracellular vesicles for targeted therapy of damaged cardiac tissue. The system homes to injured myocardium through specific molecular pathways. In a myocardial infarction model, M‐hEV effectively accumulates in the heart, reduces infarct size, alleviates ...

Multi‐Component Functionalized Bifidobacterium Longum Hydrogel for Multi‐Target Integrated Therapy of Colitis‐Associated Anxiety and Depression

Advanced Science, EarlyView.
A pH/MMP dual‐responsive Bifidobacterium longum (BL) hydrogel (INPs@BL@Gel) functionalized with baicalin, tyrosine, and inulin is constructed. It enables gastric protection, inflammation‐targeted release, and prolonged intestinal colonization. By remodeling gut microbiota, elevating beneficial neuroactive metabolites (homovanillic acid, short‐chain ...

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

Preparative Separation of Acylglycerol by Centrifugal Partition Chromatography (CPC)

Journal of Japan Oil Chemists' Society, 1992
Reacted mixtures obtained by the esterification of three purified fatty acids (oleic acid, icosapentaenoic acid, and docosahexaenoic acid) with glycerol were separated and purified into triacylglycerol, diacylglycerol, monoacylglycerol, and free fatty acid fractions by centrifugal partition chromatography (CPC).Two solvents were used in combination for
