The specific capture of live cells is crucial for various biomedical applications. Existing methods often are limited by complex production processes. This study introduces Fe-mediated monomer-adaptation polymerization (Fe-MAP), a convenient and rapid synthesis approach for selective cell capture using surface-engineered glycopolymer brushes. This method utilizes surface-initiated zerovalent iron-mediated reversible-deactivation radical polymerization (Fe-SI-RDRP), offering advantages like simplicity, biocompatibility and oxygen-tolerance due to the use of iron sheet as catalysts. We successfully employed Fe-MAP to selective capture both adherent (HeLa, L929) and suspended cells (Ramos, U937) in mammalian cell cultures. Combining excellent biocompatibility, specific and reusable cell capture capabilities, and applicability to suspended cells, Fe-MAP establishes itself as a promising strategy for selective cell capture, holding significant potential for diverse biomedical applications.

Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.

The novel multifunctional theranostic platform is highly regarded in clinical applications, often achieving desired outcomes in real-time tumor monitoring and personalized treatment. Paramagnetic micron/nanoparticles often exhibit strong magnetic resonance imaging (MRI) contrast and high photothermal conversion efficiency, making them a powerful alternative to small-molecule contrast agents for MRI diagnostics. Additionally, these particles possess high modifiability, making them highly promising for clinical use in dual-modal imaging-guided personalized tumor therapy.

Live-cell imaging of intracellular proteins enables real-time observation of protein dynamics under near-physiological conditions, providing pivotal insights for both fundamental life science research and medical applications. However, due to limitations such as poor probe permeability and cytotoxicity associated with conventional antibody-based or genetically encoded labeling techniques, live-cell imaging remains a significant challenging. To address these limitations, here in this study, we developed and rigorously validated a novel aptamer-based fluorescent probe for real-time imaging of NEK9 kinase in living cells.

Introduction: Spinal cord injury (SCI) presents a significant burden to patients, families, and the healthcare system. The ability to accurately predict functional outcomes for SCI patients is essential for optimizing rehabilitation strategies, guiding patient and family decision making, and improving patient care.
Methods: We conducted a retrospective analysis of 589 SCI patients admitted to a single acute rehabilitation facility and used the dataset to train advanced machine learning algorithms to predict patients' rehabilitation outcomes.

Immunoglobulin A nephropathy (IgAN), the most prevalent primary glomerulonephritis globally, is characterized by mesangial IgA deposition and heterogeneous clinical trajectories. Historically, management relied on renin-angiotensin system inhibition and empirical immunosuppression, yet high lifetime kidney failure risk persists despite optimized care. This review synthesizes advances in molecular pathogenesis, highlighting how the traditional multi-hit hypothesis-while foundational for targeted therapy development-fails to capture IgAN's recurrent, self-amplifying nature.
