Screening of different classes of proteases in microfilarial and adult stages of Setaria cervi.
Article in Parasitology research, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Many of the filarial proteases involved in critical physiological functions are expressed in stage-specific manner and belong to various mechanistic classes. Setaria cervi, a bovine filarial parasite express different classes of proteases. This parasite shows strong antigenic cross-reactivity with human filarial parasites Wuchereria bancrofti and Brugia malayi. Somatic extracts of S. cervi microfilariae (mf) and adult stages as well as their excretory-secretory (ES) products were screened for the presence of different classes of proteases using general (casein, bovine hemoglobin) and class specific substrates. Detergent-soluble extracts of male and female worms were also screened. Significant enzyme activity was detected in ES products both at pH 5.0 and 7.0 with casein. Cathepsin B-like activity was found to be much higher in membrane-bound extract than in the crude-soluble extract. However, it was also found to be actively secreted by both mf and adult worms. Cathepsin D-like activity assayed at pH 3.0 was very low both in somatic extract as well as in ES products. Collagenase activity at neutral pH showed higher levels, both in somatic extract and ES products. Cathepsin L-like activity was detected only in crude-soluble extract but was below detectable limit in ES products. Leucine aminopeptidase activity was significant both in crude-soluble extract and ES products. This study, thus, might be helpful for a better understanding of host-parasite interaction and identification of appropriate virulence factors that may be targeted as vaccine and/or drug targets against lymphatic filariasis.
