Screening of delta-aminolevulinic acid dehydratase from Pseudomonas strains as biosensor for lead and some other metals contamination.

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
delta-Aminolevulinic acid dehydratase (ALAD; E.C. 4.2.1.24) is a metalloprotein and plays a crucial role in heme synthesis. Its sensitivity to toxic metals depends on the metallic co-factors. In this study the effects of some heavy metals on ALADs activity of five Pseudomonas isolates from Akarçay stream (Afyonkarahisar) have been studied in order to determine whether their ALADs could be used as biosensor for lead and other heavy metals contamination. The data obtained from the study were analysed statistically by using SPSS 10.0 software for Windows. According to the results, Ni(II) increased the ALAD activity of Pseudomonas putida, Pseudomonas pseudoalcaligenes and Pseudomonas aureginosa ATTC 27853. Mn(II) also increased the enzymic activity in all strains examined except P. pseudoalcaligenes. These were found not to be statistically meaningful. P. aeruginosa 2's enzymic activity was inhibited by Mg(II) and Zn(II), significantly (p < 0.05). There was a statistically meaningful relation between enzymic activity of both P. pseudoalcaligenes, P. putida and increasing Pb(II) concentration (p < 0.05). In addition, a formula was also deviced in order to determine the doses of metals in the environment of the organisms. As a result of the study, we can suggest that Pseudomonas ALADs can be used as a biosensor for lead and some other heavy metal exposure in aquatic environments.
