Sonication dissociates the synaptic cleft and allows purification of postsynaptic densities with associated postsynaptic membrane.

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
In the synaptic junction, pre-and post compartments are anchored to each other through trans-synaptic bridges spanning the synaptic cleft. Here we demonstrate that mild mechanical disturbance through sonication dissociates the synaptic cleft, and releases PSDs adjoined to the postsynaptic membrane, but devoid of presynaptic elements. It is the first time, to our knowledge, that dissection of the synaptic cleft has been achieved without the use of chemical/enzymatic treatments. This observation suggests that some of the protein-protein interactions involved in the anchoring of pre- and postsynaptic compartments are relatively weak non-covalent associations. We describe a method for the further fractionation of PSDs with the associated postsynaptic membrane. This PSD preparation provides a valuable tool for studies of postsynaptic membrane components, such as glutamatergic receptors, in an environment closer to their native state.
