Temperature sensitivity of cardiac mitochondria in intertidal and subtidal triplefin fishes.

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
The heart is acutely sensitive to temperature in aquatic ectotherms and appears to fail before any other organ as the thermal maximum is reached, although the exact cause of this failure remains unknown. The heart is highly aerobic and therefore dependent on mitochondrial oxidative phosphorylation (OXPHOS) to meet energy requirements, but the role of cardiac mitochondria in limiting heart function at high temperatures remains unclear. We used permeabilised ventricle fibres to explore heart mitochondrial function in situ in three closely related species of small New Zealand triplefin fishes in response to temperature. We compared this to measures of whole animal respiration rates and critical oxygen tensions in these fishes. Bellapiscis medius, an intertidal species, had the greatest tolerance to hypoxia at higher temperatures and had more efficient OXPHOS at 30°C than the two subtidal species Forsterygion varium and F. malcolmi. B. medius also displayed the highest cytochrome c oxidase flux, which may in part explain how B. medius tolerates higher temperatures and hypoxia. Triplefin heart mitochondria exhibit decreased coupling to phosphorylation with increasing temperature. This most likely impairs ATP supply to the heart at elevated temperatures, potentially contributing to heart failure at ecologically relevant temperatures.
