Many life processes are regulated by physiological redox signaling, but excessive oxidative stress can damage biomolecules and contribute to disease.Neuronal microtubules are critically involved in axon homeostasis, regulation of axonal transport, and neurodegenerative processes.However, whether and how physiological redox signaling affects axonal
ABSTRACT Genotyping of 2,882 Pseudomonas aeruginosa isolates that had been collected during the last 40 years identified the ExoU-positive lineages PA14 (ST253) and ST235 as the second and third most frequent clones in the P.aeruginosa population.Both clones were approximately 2-fold more frequently detected in animate habitats than in soil or aqua
