Abstract:
... In this study, two populations of leguminous plants Lathyrus sativus were grown in four soils that were collected from sites differently contaminated by heavy metals. Evaluations included basic soil properties, concentrations of major nutrients and four metals (copper, zinc, lead and cadmium) in these soils. Investigation of Lathyrus sativus response to contamination showed that the increase of he ...

Abstract:
... Tetrahymena is a unicellular microbial eukaryotic organism that has been used extensively in toxicology and environmental research. This work attempts to model for the first time the wiring of proteins involved in cellular mechanisms of Cd toxicity in Tetrahymena thermophila. 1975 high-confidence PPIs between 68 Cd-binding proteins and 422 partners were inferred through a novel structural systems ...

Subject:
Saccharomyces cerevisiae; culture media; genes; hydrogen peroxide; myo-inositol; phenotype; phospholipids; plasma membrane; sphingolipids; transporters; yeasts
Abstract:
... Myo-inositol is a precursor of several membrane phospholipids and sphingolipids and plays a key role in gene regulation in Saccharomyces cerevisiae (S. cerevisiae). Here, we tested whether H₂O₂ was affecting the levels of the inositol transporters and thus inositol uptake. In S. cerevisiae cells adapted to H₂O₂ Itr1–GFPp accumulated in the plasma membrane until 20 min, concomitantly with an inhibi ...

Subject:
biopsy; functional status; gastritis; genes; microsatellite repeats; patients; polymerase chain reaction; provenance; stomach neoplasms; virulence
Abstract:
... Virulence factors of H. pylori, such as outer inflammatory protein A (oipA), are closely involved in the development of gastric diseases such as chronic gastritis and gastric cancer. The functional status of oipA is regulated by a repair mechanism based on CT dinucleotide repeats that influence the reading frame, thus granting the gene a functional or nonfunctional status; in other words, the func ...
