Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

Advanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...

Incidence of hyponatremia with vasopressin exposure in critically ill pediatric patients for postoperative cardiac support and shock management: A single-center, retrospective, case–control study

Journal of Pediatric Critical Care
Background: Vasopressin is used adjunctively to catecholamines for cardiovascular support but may be associated with hyponatremia. The objective of this study was to investigate the incidence of hyponatremia in critically ill pediatric patients receiving

Robots and Minimal, Physics‐Informed Features: A Hybrid Framework for Enzyme Catalysis

Advanced Science, EarlyView.
Robotic experimentation and physics‐informed machine learning combine to predict enzyme substrate scope. With a handful of interpretable features derived from docking and quantum mechanics calculations, our model rivals descriptor‐heavy AI approaches and extrapolates to unseen substrates and enzyme classes.

Synthetic Shewanella‐Bacillus Microbial Consortia for Enhanced Metal Oxide Leaching From Spent Lithium‐Ion Batteries Using Brewing Wastewater as Leaching Agent

Advanced Science, EarlyView.
A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.

Acid‐Responsive Nanobot‐Integrated Core‐Shell Microneedles Reprogram the Degenerative Annulus Fibrosus Microenvironment Through Epigenetic Suppression of Ferroptosis

Advanced Science, EarlyView.
An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

A Hypothalamic Oxytocinergic–Sympathetic Axis Couples Anxiety Dysregulation With Impaired Tendon–Bone Repair

Advanced Science, EarlyView.
RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

Vasopressin–aquaporin-2 pathway: recent advances in understanding water balance disorders [version 1; referees: 3 approved]

F1000Research, 2019
The alteration of water balance and related disorders has emerged as being strictly linked to the state of activation of the vasopressin–aquaporin-2 (vasopressin–AQP2) pathway.

A Dual‐Functional Nanoplatform Targeting the dsDNA–cGAS Axis to Mitigate Disc Degeneration and Aberrant Innervation

Advanced Science, EarlyView.
RU@PEI‐ZIF integrates dsDNA scavenging with local cGAS inhibition to suppress the dsDNA–cGAS–STING/Netrin‐1 axis in intervertebral disc degeneration. By attenuating nucleus pulposus cell senescence, inflammatory and matrix‐catabolic responses, and pathological sensory innervation, this dual‐functional nanoplatform preserves disc integrity and reduces ...

Vasopressin and Oxytocin Reduce Food Sharing Behavior in Male, but Not Female Marmosets in Family Groups

Frontiers in Endocrinology, 2017
Oxytocin (OT) is critical for lactation and maternal care, but OT and the related nonapeptide vasopressin are important for caregiving behaviors in fathers and alloparents as well.

Dual‐Function Cosubstrates Enable Threonine Dehydrogenase‐Driven Chemoenzymatic Pyrrole Synthesis

Angewandte Chemie International Edition, EarlyView.
Classical Knorr chemistry meets contemporary biocatalysis. Threonine dehydrogenase generates aminoacetone from l‐threonine, which is directly intercepted in a chemoenzymatic Knorr pyrrole synthesis. A dual‐function β‐dicarbonyl substrate serves as both pyrrole precursor and hydride acceptor for integrated NAD+ recycling, affording substituted pyrroles ...
