Polyoxometalates Mediated Amyloid Fibrillation Dynamics and Restoration of Enzyme Activity of Hen Egg White Lysozyme Treated under Cold Atmospheric Pressure Plasma.

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
Neurodegenerative disorders are one of the most devastating disorders worldwide. Although a definite mechanistic pathway of neurodegenerative disorders is still not clear, it is almost clear that these diseases are initiated by protein misfolding. Hen Egg White Lysozyme (Lyz) can be converted to highly arranged amyloid fibrils and is therefore considered a good model protein for studying protein aggregation in connection to neurodegeneration. In this study, Lyz has been converted to fibrils using He-air gas fed single jet cold atmospheric plasma (CAP). The reactive oxygen species and the reactive nitrogen species produced by the plasma jet interact with the protein molecules and enhance the fibril formation. We monitored the fibrillation kinetics with the Thioflavin T (ThT) assay and observed that fibrils are formed when the samples are treated for 10 min with He-air gas fed CAP. Further, we studied the role of a special class of inorganic nanomaterials called polyoxometalates (POMs) in the process of the Lyz fibrillation using various biophysical techniques. The Keggin POMs used in this study are phosphomolybdic acid (PMA) and silico molybdic acid (SMA). Keggin POMs bring in structural self-assembly of the protein and disrupt the fibrils as evidenced in the ThT assay and TEM analysis. Molecular docking studies together with electrokinetic potential studies show the interactions between POMs and Lyz dominated via hydrogen bonding and electrostatic interactions. The enzyme activity of Lyz was assessed using the substrate
