Surface‐Spin‐Induced Magnetic Loss Enhancement in Ultralight Electromagnetic Absorbers

open access: yesAdvanced Science, EarlyView.
Fe3O4 nanoparticles with different hollow rates were synthesized to demonstrate the key role of surface moment in magnetic loss process. Using the same volume filling ratio, the 54.1% hollow Fe3O4 absorber represents about 20% enhancement in the imaginary part (μ'') than solid particles due to the coexisting magnetic resonance of inside and outside ...

Association of disease activity score (DAS) 28 with subsets of rheumatoid factor and anti-cyclic citrullinated peptides (anti-CCP) among rheumatoid arthritis patients in North India

open access: yes, 2023
297-302Rheumatoid factor (RF), anticyclic citrullinated peptides (Anti-CCP), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) are used as disease markers for rheumatoid arthritis (RA). However, correlation of disease activity score (DAS)

Cobalt Single‐Atom Nanozyme for Enhanced Intestinal Radioprotection and Tumor Radiosensitization via Bidirectional ROS Modulation

open access: yesAdvanced Science, EarlyView.
Orally administered, pH‐responsive Co‐SAN exerts dual functions: in the alkaline intestinal milieu, it scavenges reactive oxygen species (ROS) and suppresses the PI3K/AKT pathway and NETs formation, thus providing radioprotection; whereas in the acidic tumor microenvironment, it generates ROS and alleviates hypoxia, thereby enhancing radiosensitization.

D–A Type Perylene Micelles With Synergistic Charge/Energy Transfer for Dual‐Path ROS Generation and Enhanced Photocatalysis

open access: yesAdvanced Science, EarlyView.
Dual‐state activation of singlet and triplet excitons is achieved in perylene‐based nanomicelles via donor engineering. By synergistically pairing charge transfer with energy transfer pathways, while concurrently enabling pollutant pre‐enrichment, this strategy establishes spatial coupling between efficient ROS generation and rapid mineralization ...

Experience‐Dependent Reorganization of Hippocampal CA3 Neuronal Ensembles Associates With Memory Generalization

open access: yesAdvanced Science, EarlyView.
Mice can transfer the learned rule of spatial working memory to guide similar but novel tasks. Hippocampal CA3 populational activity dynamically reorganize during memory generalization, shifting from task‐specific to generalized coding over testing days. Sparse yet redundant neural representations of CA3 enable rule transfer and cognitive map formation,
