Albendazole enantiomeric metabolism and binding to cytosolic proteins in the liver fluke Fasciola hepatica.
Article in Veterinary research communications, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Fascioliasis causes important economic losses in ruminant species all over the world. Its control is largely based on the use of the flukicidal compound triclabendazole (TCBZ). However, its chemically related benzimidazole anthelmintic albendazole (ABZ) is being successfully used to control TCBZ-resistance flukes. This research gains some insights into the comparative molecular behaviour of both anthelmintics within the target fluke. The goals of the current work were: (i) to assess the competitive binding of ABZ and TCBZ to cytosolic proteins of F. hepatica, and (ii) to evaluate the enantioselective biotransformation of ABZ in microsomal fractions obtained from TCBZ-susceptible and TCBZ-resistant strains of the liver fluke. Cytosolic proteins from fluke specimens bound TCBZ with greater affinity (83%) than ABZ (44%) and the fraction of TCBZ bound to cytosolic proteins was not displaced by ABZ. The microsomes from both -susceptible and resistant flukes sulphoxidized ABZ into ABZ sulphoxide (ABZSO). However, this oxidative activity was 49% higher in microsomes from TCBZ-resistant flukes (P < 0.001) with a predominant production of the (+) ABZSO enantiomer. As earlier shown for TCBZ, the results reported here confirm an enhanced ability for ABZ oxidation in TCBZ-resistant flukes. While this enhanced oxidative metabolism of ABZ may cooperate to the resistance phenomenon, other pharmacodynamic-based mechanisms may be involved, which would explain why, although being chemically-related, ABZ remains efficacious against TCBZ resistant flukes under field conditions.
