Study on the interaction between isoniazid and bovine serum albumin by fluorescence spectroscopy: the effect of dimethylsulfoxide.
Article in Molecular biology reports, 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 investigation of the binding between isoniazid (or isonicotinic acid hydrazide, INH) and serum albumin is of crucial importance to reveal the reason of resistant Mycobacterium tuberculosis strains towards INH and to increase the anti-tuberculous activity of INH. The interaction between INH and bovine serum albumin (BSA) was studied by fluorescence, UV and FT-IR spectroscopy methods. The analysis of the emission quenching at different temperatures revealed that the quenching mechanism corresponds to a static process and, as consequence; a complex INH-BSA is formed. The modified Stern-Volmer quenching constant K (a) and the corresponding thermodynamic parameters ΔH, ΔG and ΔS were calculated. The distance, r, between donor (BSA) and acceptor (INH) was calculated to be 2.14 nm based on Förster's non-radiative energy transfer theory (FRET). The results obtained on the basis of fluorescence study of BSA solutions at the presence of dimethylsulfoxide (DMSO) were discussed in terms of the hydration properties and competitive intermolecular interactions between BSA and solvent components. The dependence of binding constant on the concentration of added DMSO as a solvent component showed non monotonous behavior. The conformational changes of BSA and its secondary structure alterations at the presence of INH were revealed.
