1 · What the graph read from it

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.

2 · The registry

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

The role of metabotropic l-glutamate (mGlu) receptors in supralinear Ca(2+) signaling was investigated in cultured hippocampal cells using Ca(2+) imaging techniques and whole-cell voltage-clamp recording. In neurons, but not glia, global supralinear Ca(2+) release from intracellular stores was observed when the mGlu receptor agonist (RS)-3,5-dihydroxyphenylglycine (DHPG) was combined with elevated extracellular K(+) levels (10.8 mm), moderate depolarization (15-30 mV), or NMDA (3 micrometer). There was a delay (2-8 min) before the stores were fully charged, and the enhancement persisted for a short period (up to 10 min) after removal of the store-loading stimulus. Studies with the mGlu receptor antagonist 2-methyl-6-(phenylethynyl)-pyridine demonstrated that these effects were mediated by activation of the mGlu(5) receptor subtype. The L-type voltage-gated Ca(2+) channel antagonist nifedipine (10 micrometer) substantially reduced responses to DHPG obtained in the presence of elevated extracellular K(+) but not NMDA. This suggests that the Ca(2+) that is required to load the stores can enter either through L-type voltage-gated Ca(2+) channels or directly through NMDA receptors. The findings that both depolarization and NMDA receptor activation can facilitate mGlu receptor Ca(2+) signaling adds considerable flexibility to the processes that underlie activity-dependent changes in synaptic strength. In particular, a temporal separation between the store-loading stimulus and the activation of mGlu receptors could be used as a recency detector in neurons.
