Structure-function studies of Bubalus bubalis lingual antimicrobial peptide analogs.
Article in Veterinary research communications, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Antimicrobial peptides expressed on different epithelial lining are major components of the innate immune system. Based on the deduced amino acid sequence of Bubalus bubalis lingual antimicrobial peptide (LAP) cDNA (Accession No. DQ458768), five overlapping peptides LAP(23-55), LAP(42-64), LAP(21-64), LAP(1-26) and LAP(1-64) were synthesized using solid phase fluorenylmethoxycarbonyl (Fmoc) chemistry. Circular Dichroism spectroscopy of synthesized peptides revealed predominantly beta-structure for LAP(23-55,) LAP(42-64) and LAP(21-64) with less alpha-helix in different solutions. Quantitation of secondary structure indicated the highest beta-structure for all these three peptides in membrane mimetic SDS solution. The helicogenic solvent TFE could not induce helix in LAP(23-55) however TFE induced helical propensity was observed in LAP(42-64) and LAP(21-64). The quantitation of secondary structure indicated the highest ordered structure for LAP(23-55) followed by LAP(42-64) and LAP(21-64). The antibacterial activity of LAP(23-55) was found to be more potent against Staphylococcus aureus, Listeria monocytogens, Escherichia coli and Salmonella typhimurium followed by LAP(42-64) and LAP(21-64). Minimum inhibitory concentration (MIC) also showed similar trend with lowest value for LAP(23-55) followed by LAP(42-64) and LAP(21-64). Haemolysis and cytotoxicity was observed above 3 fold for LAP(21-64,) above six fold for LAP(23-55) and LAP(42-64) of their MIC. The LAP(1-26) and LAP(1-64) could not produce any characteristic CD spectra and did not show any antimicrobial activity, indicating that N- terminal of the peptide negates the antimicrobial activity.
