Manipulating energy migration in nanoparticles toward tunable photochromic upconversion.

Smart control of energy interactions plays a key role in manipulating upconversion dynamics and tuning emission colors for lanthanide-doped materials. However, quantifying the energy flux in particular energy migration in the representative sensitizer-activator coupled upconversion system has remained a challenge. Here we report a conceptual model to examine the energy flux in a single nanoparticle by designing an interfacial energy transfer mediated nanostructure.

Human respiratory organoids sustained reproducible propagation of human rhinovirus C and elucidation of virus-host interaction.

The lack of a robust system to reproducibly propagate HRV-C, a family of viruses refractory to cultivation in standard cell lines, has substantially hindered our understanding of this common respiratory pathogen. We sought to develop an organoid-based system to reproducibly propagate HRV-C, and characterize virus-host interaction using respiratory organoids. We demonstrate that airway organoids sustain serial virus passage with the aid of CYT387-mediated immunosuppression, whereas nasal organoids that more closely simulate the upper airway achieve this without any intervention.

An antibody cocktail targeting two different CD73 epitopes enhances enzyme inhibition and tumor control.

CD73, an ectoenzyme responsible for adenosine production, is often elevated in immuno-suppressive tumor environments. Inhibition of CD73 activity holds great promise as a therapeutic strategy for CD73-expressing cancers. In this study, we have developed a therapeutic anti-human CD73 antibody cocktail, HB0045.

Pickering Emulsions Stabilized by Pea Protein Isolate-Cellulose Conjugates Prepared via the Maillard Reaction and Their Application in Active Substance Protection.

The development of innovative solid particles from renewable resources possessing high biocompatibility and exceptional emulsification capabilities is crucial for stabilizing Pickering emulsions and advancing carrier systems. In this study, a pea protein isolate (PPI)-cellulose conjugate particle was prepared by the Maillard reaction. Compared to the isoelectric point of pH 4.

Efficient removal of Sb(III) from aqueous solution using TiO precipitated onto waste herb-residue biochar.

Increasing antimony (Sb) pollution has become a global concern, but there is still a lack of economically efficient adsorbents for its remediation. In this study, a novel remediation material was developed by precipitating TiO onto waste herb-residue biochar (named TBC). The effectiveness and adsorption mechanisms of the material for Sb(III) removal were investigated through adsorption experiments, and the enhancement pathway of traditional herb decoction on the effectiveness of modified biochar was analyzed.
