Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

open access: yesAdvanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...

A Chiral Virus‐Like Nanoplatform That Broadly Mediates Antibiotic Delivery to the Brain for Bacterial Meningitis Therapy

open access: yesAdvanced Science, EarlyView.
Chiral virus‐mimicking mesoporous silica nanostructures (CVSNs) efficiently transport diverse antibiotics across the blood–brain barrier (BBB) into brain parenchyma and cerebrospinal fluid. By enhancing delivery to microglia and astrocytes, CVSNs improve antibiotic bioavailability and therapeutic efficacy against both Gram‐negative and Gram‐positive ...

A Water Compartment Cell Culture Lid Enables Stable Longitudinal Recording of Neuronal Networks In Vitro

open access: yesAdvanced Science, EarlyView.
A cell culture lid with an integrated water compartment eliminates evaporation from microelectrode arrays while preserving gas exchange. Freed from the osmotic drift and repeated medium exchanges that disturb conventional recordings, patterned human iPSC‐derived neuronal networks are recorded continuously for five weeks. Single‐spike resolution reveals

Molecular Basis of NPY Recognition and Ligand Selectivity at the Neuropeptide Y5 Receptor

open access: yesAngewandte Chemie, EarlyView.
Here, we present the first active structure of the neuropeptide Y5 receptor (NPY5R) in complex with its endogenous ligand NPY and the Gi1 protein. The cryo‐electron microscopy structure, validated by extensive mutagenesis studies, gives important insights into the molecular mechanisms underlying ligand binding and receptor activation.

Small Intestinal Bacterial Overgrowth Following Gastrointestinal Cancer Surgery: Current Evidence and Future Perspectives

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Small intestinal bacterial overgrowth (SIBO) has recently gained increasing attention as a potential cause of postoperative gastrointestinal symptoms following gastrointestinal cancer surgery. Surgical procedures can disrupt normal gastrointestinal physiology through anatomical reconstruction, impaired motility, reduced gastric acid secretion,

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

open access: yesAdvanced Science
Chromosome segregation in the human pathogen Streptococcus pneumoniae relies on the membrane‐binding protein RocS, which links the chromosomal DNA to the membrane.

Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

open access: yesAdvanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...
