Electromechanical Regulation Underlying Protein Nanoparticle-Induced Osmotic Pressure in Neurotoxic Edema.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Osmotic imbalance is a critical driving force of cerebral edema. Protein nanoparticles (PNs) amplify intracellular osmotic effects by regulating membrane potential and homeostasis of water and multiple ions. This study has investigated how PNs control the neuronal swelling through electromechanical activity. Methods: The fluorescence resonance energy transfer (FRET)-based Vimentin force probe was used to real-time monitor the osmotic tension in neurons. Patch clamp and the living cell 3D imaging system were applied to explore the relationship between cell electromechanical activity and cell volume in different cytotoxic cell models. Cytoplasmic PN amount measured by the NanoSight instrument, ion contents detected by the freezing point osmometer and ion imaging were performed to investigate the role of PNs in regulating cell swelling. Results: We observed a close association between neuronal swelling and changes in osmotic tension and membrane potential. The tension effect of biological osmotic pressure (OP) relies on electromechanical cooperation induced by intracellular PN and Ca Conclusion: Our findings indicate that PNs, Ca
