Effects of novel dinuclear cisplatinum(II) complexes on the electric properties of human breast cancer cells.

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 aim of this study was to determine the influence of cisplatin and novel dinuclear platinum(II) complexes on the electrical properties of the membrane and the level of lipid peroxidation in the human breast cancer cell lines MDA-MB-231 and MCF-7. The basal electrical surface properties of cells are known. Changes in cell function may affect these surface properties, and those changes can be detected by electrokinetic measurements. The surface charge density of the breast cancer cell lines MDA-MB-231 and MCF-7 were measured as a function of pH. A four-component equilibrium model was used to describe the interaction between the solution ions and the breast cancer cell surface. The experimental and the theoretical charge variation curves of the breast cancer cells at pH 2.5-9 were in agreement. Measurements of the cellular malondialdehyde levels with high performance liquid chromatography were used to determine the extent of lipid peroxidation. The acid and base functional group concentrations and average association constants with hydroxyl ions were smaller in breast cancer cell membranes treated with cisplatin or novel dinuclear platinum(II) complexes compared with untreated cancer cells, and the average association constants with hydrogen ions were higher. The levels of lipid peroxidation products in breast cancer cells treated with cisplatin or novel dinuclear platinum(II) complexes were also higher than in untreated cancer cells.
