Resealing of electroporation of porcine epidermis using phospholipids and poloxamers.

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 resealing of porcine epidermis after electroporation is investigated. Porcine epidermis was subjected to electroporation (30 pulses at 100 V, 1 ms and at 1 Hz) in a vertical diffusion apparatus, in the presence of 2 mg/ml dimyristoylphosphatidylserine, to produce a long lasting permeable state. Resealing treatments include incubation in 0.0625-0.25 mM poloxamer 188 (P188), or incorporation of phosphatidylcholines (PC) and/or cationic lipids with additional pulses. The recovery of electric resistance of the epidermis samples after electroporation with or without resealing treatments was monitored. The transports of carboxyfluorescein and glucose were measured during the recovery process. Both P188 and PC were effective in resealing in terms of electric conductance and transport, with P188 reacting more rapidly and completely. P188 mediated lipid exchange between stratum corneum lipid particles was measured by fluorescence resonance energy transfer (FRET). Lipid reorganization facilitated by P188 and PC is suggested to be a major resealing mechanism of electroporation damage.
