Safety assessment of titanium dioxide (E171) as a food additive.

With respect to genotoxicity, the Panel concluded that TiO particles have the potential to induce DNA strand breaks and chromosomal damage, but not gene mutations. No clear correlation was observed ...

Positive epistasis of major low-cost drug resistance mutations rpoB531-TTG and katG315-ACC depends on the phylogenetic background of Mycobacterium tuberculosis strains.

epidemic. Here we analysed the transmission capacity of these strains in the context of their phylogenetic background and drug resistance mutations. The study collection included all multidrug resistant (MDR) ...

Model-Based Classification for Digital PCR: Your Umbrella for Rain.

of precision, both at individual partition level and at the level of the global concentration. We illustrate our method on genetically modified organism, inhibition, dynamic range, and mutation ...

Genetic elements associated with antimicrobial resistance among avian pathogenic Escherichia coli.
