Two novel subphthalocyanines substituted axially with a BODIPY or distyryl BODIPY moiety have been synthesized. Both systems exhibit a highly efficient photoinduced energy transfer process, either from the excited BODIPY to the subphthalocyanine core (for the former) or from the excited subphthalocyanine to the distyryl BODIPY unit (for the latter).

The challenge of "false positive" signals significantly complicates tumor localization and surgical resection, which are pivotal for successful tumor surgeries. Therefore, the development of a method for preoperative tumor localization and intraoperative margin determination holds considerable promise for improving surgical outcomes. In this study, a zero-crosstalk ratiometric tumor-targeting near-infrared (NIR) fluorescent probe was developed for precise cancer diagnosis and intraoperative navigation via NIR fluorescence imaging.

Mechanistic understanding of the inhibitory immunoreceptor PD-1 is largely based on mouse models, but human and mouse PD-1 share only 59.6% amino acid identity. Here, we found that human PD-1 is more inhibitory than mouse PD-1, owing to stronger interactions with the ligands PD-L1 and PD-L2 and more efficient recruitment of the effector phosphatase Shp2.

Pd-based nanocatalysts hold significant promise for application in alkaline direct ethanol fuel cells (DEFCs). To address the challenges of low Pd atom utilization and poor reaction kinetics in conventional Pd-based catalysts, a self-etching strategy has been developed to synthesize PdPb nanoparticles (NPs) with tunable size and abundant tensile strain. The nanoparticles demonstrated a markedly enhanced electrocatalytic performance.

Article Synopsis
- Asymptomatic Alzheimer's disease (AsymAD) is characterized by the presence of Alzheimer's pathology in individuals who maintain cognitive function, showing lower neuroinflammation compared to symptomatic Alzheimer's disease cases.
- Research using postmortem brain samples revealed that AsymAD subjects have unique characteristics such as enriched core plaques and reduced tau aggregation, along with increased microglial activity around amyloid plaques.
- The study suggests that the composition of the plaque microenvironment, particularly enhanced actin-based motility pathways in microglia, may play a key role in the resilience to Alzheimer's pathology and cognitive decline in AsymAD individuals.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the deposition of amyloid-beta and hyperphosphorylated tau (P-tau) proteins in the brain. P-tau accumulates in neurons and is strongly associated with AD severity and affected brain regions. However, only a subset of neurons in AD exhibit tau pathology.
