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

AIM AND

methodsSimvastatin (SV) is reported to improve cognition and slow the progression of Alzheimer's disease (AD). This study explored the mechanisms underlying the antiamnesic effect of SV in AD using behavior tests, histological examination, western blot analysis, and electrophysiological recording technique in AD model mice created by intracerebroventricular injection (i.c.v.) of Aβ25-35 .

resultsChronic administration of SV (40 mg/kg/day) for 11 days after Aβ25-35 -injection ameliorated the impairment of acquisition performance and probe trail test in Morris water maze task and alternation behavior in Y maze task in Aβ25-35 -mice. Aβ25-35 -induced apoptosis of hippocampal CA1 pyramidal cells and Aβ25-35 -impaired high-frequency stimulation (HFS)-dependent long-term potentiation (LTP) induction in hippocampal Schaffer collaterale-CA1 synapse were rescued by SV-treatment. SV prevented Aβ25-35 -inhibited protein kinase B (Akt) and extracellular signal-related kinase-2 (ERK2) phosphorylation, which was sensitive to α7 nicotinic acetylcholine receptor (α7nAChR) antagonist MLA. SV-induced neuroprotection was attenuated by MLA or phosphatidylinositol-3-kinase (PI3K) antagonist LY294002. SV-rescued LTP induction was blocked by α7nAChR, PI3K or MAPK/ERK kinase (MEK) antagonist. Finally, the antiamnesia of SV in Aβ25-35 -mice was attenuated by blockage of SV-induced neuroprotection or SV-rescued LTP induction.

conclusionThe antiamnesia of SV in Aβ25-35 -mice depends on its neuroprotection and synaptic plasticity improvement.
