High-Level Expression of Immunogenic Recombinant Plasmodium vivax Merozoite Surface Protein (Pvmsp-142 kDa) in pGEX 6P1 Vector.
Article in Iranian journal of public health, 2015. 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
backgroundDetection of Plasmodium vivax specific antibodies with serological tests could be a valuable tool for epidemiological researches. Whereas P. vivax cannot be simply obtained in vitro, serological tests using total or semi-purified antigens are infrequently used. Given this restriction, the present study investigated whether recombinant P. vivax merozoite surface protein 1 (PvMSP-1 42 kDa) could be useful in detection of antibodies from the serums of a P. vivax infected person using serological tests.
methodsParasite DNA was extracted from blood sample of an Iranian P. vivax-infected patient. The region of PvMSP-142 kDa was amplified by PCR then cloned into pTZ57R/T vector and sequenced. The insert was sub cloned into pGEX 6P1 expression vector. Afterwards, it was transformed into E. coli BL21 and cultured massively. Sub cloning of gene was confirmed by PCR and enzyme digestion and sequencing finally. Production of recombinant protein was confirmed by SDS-PAGE. Western blot was performed by human sera to appraisal binding ability to the IgG antibodies of P. vivax infected patients. Recombinant protein was purified and estimated by Bradford assay.
resultsThe specialty values of the Western blot determined with 10 sera from naturally infected individuals, 10 sera from healthy individuals and 7 sera from individuals with other infectious diseases.
conclusionFor the Iranian population, using a Western blot assay for MSP-142 recombinant protein can be used as the foundation for promotion of serological assay for the detection of P. vivax malaria such as ELISA.
