A DNP‐Supported Solid‐State NMR Approach to Study Nucleic Acids In Situ Reveals Berberine‐Stabilized Hoogsteen Structures in Mitochondria

Angewandte Chemie, EarlyView.
Mitochondria are vital for energy production and rely on intricate nucleic acid structures to regulate gene expression. Using DNP‐ssNMR (dynamic nuclear polarization solid‐state NMR), we observed G‐quadruplex formation in intact mitochondria treated with berberine.

Poligromorph Materials: Shape Morphing Functional Polyvinyl Alcohol/Maleic Anhydride Ethylene‐Propylene/Carbon Composites in Aqueous and Hydrocarbon‐Based Media

Advanced Intelligent Systems, EarlyView.
Hygromorphic materials, such as pinecone scales, respond to humidity changes. This study presents poligromorphic composites—composed of carbon fibers (CFs), polyvinyl alcohol (PVA), and maleic anhydride ethylene‐propylene (MA‐EPR)—that react to water, humidity, and hydrocarbons.

4D Printing of Polyethylene Glycol‐Grafted Carbon Nanotube‐Reinforced Polyvinyl Chloride–Polycaprolactone Composites for Enhanced Shape Recovery and Thermomechanical Performance

Advanced Intelligent Systems, EarlyView.
This study introduces polyethylene glycol‐functionalized carbon nanotubes (CNTs) to enhance dispersion, interfacial bonding, and 4D printability in polyvinyl chloride‐PCL nanocomposites. The optimized 4D composite (0.5 wt% CNT) achieves a 25% increase in tensile strength, 95.78% shape fixity, and 5‐s recovery time.

Reactive microglia are the major source of tumor necrosis factor alpha and contribute to astrocyte dysfunction and acute seizures in experimental temporal lobe epilepsy

Glia, Volume 71, Issue 2, Page 168-186, February 2023., 2023
Main Points Microglia become rapidly reactive in temporal lobe epilepsy (TLE). Microglia are major producers of TNFα during status epilepticus, which impairs astrocyte coupling and promotes gliosis. Depletion of microglia attenuates acute seizure activity in TLE.
