Evidence for intestinal heterogenic expression of di-tripeptides transporter PepT1 during experimental cryptosporidiosis in neonatal rats.
Article in Parasitology research, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Cryptosporidium parvum is a protozoan parasite that causes intestinal malabsorptive syndrome and malnutrition. Considering the importance of di-tripeptide absorption for nutritional status, we previously investigated the regulation of PepT1 transporter in the suckling rat model of acute cryptosporidiosis and showed that PepT1 protein expression and activity were not modified in the parasitized intestine. Here we used confocal microscopy performed on intestinal villi to determine the subcellular localization of PepT1 together with f-actin and parasites. For this purpose, confocal microscopy using vibratome thick sections was developed on the distal small intestine, the preferential site of parasite implantation. Results showed major heterogeneity of apical PepT1 expression among enterocytes, which did not correlate with actin staining or parasite implantation. These results underscore the importance of considering the effect of C. parvum at the cellular scale and not only in the entire epithelium.
