Advancing age alters the contribution of calcium release from smooth endoplasmic reticulum stores in superior cervical ganglion cells.
Article in The journals of gerontology. Series A, Biological sciences and medical sciences, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
unlabelledIn superior cervical ganglion (SCG) neurons calcium-induced calcium release (CICR), mediated by ryanodine receptors (RyRs), contributes to stimulation-evoked intracellular calcium ([Ca(2+)](i)) transients. HYPOTHESIS: The contribution of CICR to electrical field stimulation (EFS)-evoked [Ca(2+)](i) transients in SCG cells declines with senescence and may be partially recovered in the presence of caffeine. We measured EFS-evoked [Ca(2+)](i) transients in isolated fura-2-loaded SCG cells from Fischer-344 rats aged 6, 12, and 24 months with either the RyR antagonist ryanodine to block the contribution of CICR to [Ca(2+)](i) transients or caffeine to sensitize CICR to EFS. EFS-evoked [Ca(2+)](i) transients increased from 6 to 12 months and declined at 24 months and ryanodine decreased [Ca(2+)](i) transients in SCG cells from 6- and 12-month-old animals only. Caffeine significantly increased EFS-evoked [Ca(2+)](i) transients in all age groups. These data suggest that CICR declines with senescence and residual CICR function may be reclaimed in senescent cells with caffeine.
