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

Uterine transplantation is currently the only solution that enables women with absolute uterine factor infertility to become pregnant and give birth to a child. In the preparatory phase of a human uterus transplantation, the sheep is the most recommended species. Cold ischaemia, i.e., a period of reduced or absent blood flow at cold conditions, can significantly impair the function of the transplanted organ. Cold ischaemia impairs smooth muscle function in general and reduces smooth muscle contractile activity. However, it seems to provide some protection against cold storage. Our main goal was to investigate the molecular mechanisms leading to reversible changes in myometrial myofilaments and to distinguish these from permanent changes, which was supported by histological imaging of uterine samples. Using fluorescence spectroscopy, we investigated important interactions between major components of smooth muscle such as actin and tissue-specific actin-binding proteins. We characterized functional changes by denaturation sensitivity and protein-protein interactions under low and high salt conditions by intrinsic tryptophan, Alexa488-phalloidin and eosin fluorescence emission spectroscopy assays. Our results suggest that short-term cold ischaemia causes minor disruption of muscle cells. The protein extracts of myometrium contained large amounts of actin, which was present in soluble complexes with actin-binding proteins after ischaemic stress. The results indicate that the contractile filament system underwent molecular stabilization and reassembly due to ischaemic stress and that the actin monomers were unable to form polymers due to increased heterologous protein-protein interactions. The content of necrotic proteins cannot be detected after brief ischaemia, but eosin selectively binds to large proteins (caldesmon, myosin chains, tropomyosin) and protein complexes. Based on these results, we can assume that short-term preservation of cold ischaemia in uterine transplantation reduces the risk of using it in clinical trials for complete myometrial recovery after reperfusion.
