893. Effects of silver nanoparticles and ions on a co-culture model for the gastrointestinal epithelium
Date: 18-02-16 

Background The increased incorporation of silver nanoparticles (Ag NPs) into consumer products makes the characterization of potential risk for humans and other organisms essential. The oral route

894. Combining -Omics to unravel the impact of copper nutrition on alfalfa (Medicago sativa) stem metabolism
Date: 15-02-16 

Copper can be found in the environment at concentrations ranging from a shortage up to the threshold of toxicity for plants, with optimal growth conditions situated in between. The plant stem plays a

895. Escherichia coli under ionic silver stress: An integrative approach to explore transcriptional, physiological and biochemical responses
Date: 27-01-16 

For a better understanding of the systemic effect of sub-lethal micromolar concentrations of ionic silver on Escherichia coli, we performed a multi-level characterization of cells under Ag+-mediated

896. In situ phenotypic heterogeneity among single cells of the filamentous bacterium Candidatus Microthrix parvicella
Date: 05-01-16 

Microorganisms in biological wastewater treatment plants require adaptive strategies to deal with rapidly fluctuating environmental conditions. At the population level, the filamentous bacterium

897. High-resolution high-sensitivity elemental imaging by secondary ion mass spectrometry: from traditional 2D and 3D imaging to correlative microscopy
Date: 07-10-15 

Secondary ion mass spectrometry (SIMS) constitutes an extremely sensitive technique for imaging surfaces in 2D and 3D. Apart from its excellent sensitivity and high lateral resolution (50 nm on
