Spatiotemporally Controlled Tumor Photodynamic/Immunotherapy Therapy Based on Upconversion Hybrid Nanosystem

open access: yesAdvanced Science, EarlyView.
PURH is constructed by a five‐layer upconversion nanoparticle (UCNP) surface coated with mesoporous silica, which encapsulates rose bengal (RB) within the mesoporous channels. Additionally, CpG oligonucleotides (CpG ODN) is linked to the surface, followed by the surface functionalization of hyaluronic acid (HA). This spatiotemporally controllable smart

An Allosteric Modulator of the Adenosine A1 Receptor Improves Cardiac Function Following Ischaemia in Murine Isolated Hearts

open access: yesPharmaceuticals, 2013
The effect of an allosteric modulator of the adenosine A1 receptors was investigated using an ischaemia-reperfusion protocol in murine isolated hearts. Isolated hearts were perfused with Kreb-Henseleit solution gassed with carbogen gas (95% O2 and 5% CO2)

Macrophage Phenotype Detection Methodology on Textured Surfaces via Nuclear Morphology Using Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
A novel machine learning approach classifies macrophage phenotypes with up to 98% accuracy using only nuclear morphology from DAPI‐stained images. Bypassing traditional surface markers, the method proves robust even on complex textured biomaterial surfaces. It offers a simpler, faster alternative for studying macrophage behavior in various experimental
