Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Pharmacological Microglial Inhibition Remodels the Scar Microenvironment to Support Reticulospinal Circuit Reconstruction After Spinal Cord Injury

Advanced Science, EarlyView.
This study establishes pharmacological microglial inhibition as a therapeutic strategy, demonstrating its capacity to remodel the lesion microenvironment through significant reduction of extracellular matrix deposition. This permissive environmental transformation facilitates robust regeneration of the reticulospinal tract, and reconstructs functional ...

HMGB2 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through MTA2‐Driven Metabolic Reprogramming

Advanced Science, EarlyView.
In contrast to the adult mammalian heart, which lacks regenerative capacity, the neonatal heart retains a transient regenerative capacity. In this study, high mobility group box 2 (HMGB2) is identified as a crucial protein driving heart regeneration based on comprehensive analyses using quantitative proteomics with tandem mass tag (TMT) labelling, RNA ...

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...
