Potent anti-HIV activities and mechanisms of action of a pine cone extract from Pinus yunnanensis.
Article in Molecules (Basel, Switzerland), 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The anti-HIV activities of a pine cone extract (YNS-PY-F) from Pinus yunnanensis have been evaluated, and its mechanisms of action were also explored. The pine cone extract, YNS-PY-F, potently inhibited HIV-1(IIIB), HIV-1(RF), HIV-1(A17), HIV-1(AO18) and HIV-2(ROD) and induced cytopathic effect in C8166 cells with EC₅₀ values of 0.96 μg/mL, 1.53 μg/mL, 0.88 μg/mL, 7.20 μg/mL and 6.17 μg/mL, respectively. The quantification of a p24 production assay showed that YNS-PY-F significantly inhibited the acute replication of HIV-1(IIIB), HIV-1RF, HIV-1(A17) and HIV-1(AO18) in C8166 cells. An MTT assay showed that YNS-PY-F also significantly inhibited the HIV-1(IIIB) induced cytolysis in MT-4 cells with an EC₅₀ value of 2.22 μg/mL. The mechanism assays showed that YNS-PY-F had potent inhibitory effects on the fusion between infected cells and uninfected cells, and the activity of HIV-1 reverse transcriptase, with EC₅₀ values of 7.60 μg/mL and 4.60 μg/mL, respectively. Overall, these data suggest that the pine cone extract from Pinus yunnanensis has potent inhibitory activities against HIV-1(IIIB), HIV-1(RF), RT inhibitor-resistant strains HIV-1(A17) and HIV-1(AO18), and HIV-2(ROD), and its anti-HIV mechanisms include inhibition of HIV entry and inhibition of reverse transcriptase activity.
