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

aimSarcopenia - aging-related loss of muscle mass and muscle strength - is a key feature of the frailty model. In the present study, we aimed to elucidate the molecular biological changes associated with aging in the extensor digitorum longus muscle of senescence-accelerated mouse prone 8 mouse model by capillary electrophoresis-mass spectrometry.

methodsThree groups of senescence-accelerated mouse prone 8 mice were used, namely, 12-week-old (young; n = 5), 40-week-old (elderly; n = 5) and 55-week-old mice (late elderly; n = 5). The extensor digitorum longus muscle was collected. After preliminary analyses, metabolome analysis was carried out by capillary electrophoresis-mass spectrometry. Additionally, we examined whether the activity of enzymes in the metabolic pathway fluctuated with aging, by real-time polymerase chain reaction.

resultsAmong the 116 water-soluble metabolites associated with the central energy metabolism pathway, changes were observed in 19 metabolites between 12- and 40 -weeks-old, in 40 metabolites between 40- and 55-weeks-old, and in 57 metabolites between 12- and 55-weeks-old. The fluctuated metabolites that were common among the groups were Val, putrescine and His. The levels of putrescine, associated with cell proliferation, protein synthesis and nucleic acid synthesis, and β-Ala and His, a component of carnosine that is characterized by its anti-oxidant and anti-fatigue effects, decreased with age.

conclusionsWe confirmed that there were two aging-related metabolic changes in the extensor digitorum longus muscle of senescence-accelerated mouse prone 8 mice. Based on the changes in metabolites, cell senescence and fatigue in the extensor digitorum longus muscle might increase in old mice compared with those in young mice, showing molecular biological changes with aging.
