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

introductionNitric oxide (NO) is an intracellular and intercellular messenger that plays an important role in cellular events in physiological and pathophysiological processes. NO is one of the inflammation markers and macrophages of an inflammatory cell produce a large amount of NO compared with other cells. Non-invasive detection system of NO is highly required to realize an early therapeutic treatment considering the process of pathophysiological changes. The objective of this study is to develop an imaging agent of nitric oxide (NO).

methodsA water-insoluble DAR-4M of fluorescent dye for NO was solubilized in water through the micelle formation with gelatin grafted with l-α-phosphatidylethanolamine distearoyl (DAR-4M micelles). Physicochemical and biological properties of DAR-4M micelles were investigated by using cultured cells and animals.

resultsThe DAR-4M micelles responded to NO secreted from a NO donors, in contrast to the same concentration of free DAR-4M. When RAW264.7 of a macrophage cell line was stimulated by lipopolysaccharide (LPS) to allow them to generate NO, the DAR-4M micelles could detect NO of the cells to a significant great extent compared with free DAR-4M. After the intravenous injection of DAR-4M micelles or free DAR-4M to a mouse model of aristolochic acid (AA) induced acute interstitial nephritis, the DAR-4M micelles enhanced the fluorescence intensity from the kidneys to a significant great extent compared with the free DAR-4M injection. In case of DAR-4M micelles injection into normal mice, such an enhanced kidney fluorescence was not observed. A body distribution experiment demonstrated that the kidney accumulation of DAR-4M micelles was not modified by the AA-induced inflammation. After the AA injection, the number of CD11b-positive cells increased with time, indicating the increased number of inflammatory macrophages.

conclusionDAR-4M micelles are effective in imaging NO generated from macrophages accompanied with inflammation.
