Two Gram-stain-positive, aerobic actinomycete strains, designated NEAU-PCY-3T and NEAU-PCY-4, were isolated from rhizosphere soil of Urtica urens L. collected from Anshan, Liaoning Province, northeast PR China. The 16S rRNA gene sequence analysis showed that the two strains exhibited 99.9 % 16S rRNA gene sequence similarity with each other and that they were most closely to Longispora fulva DSM 45356T (98.7, 98.9 %) and Longispora albida JCM 11711T (97.1, 97.2 %). Phylogenetic analysis based on the 16S rRNA gene sequences indicated that the two strains were located in the same lineage and formed a cluster with the genus Longispora...

The taxonomic status of strain M16386T, a nitrogen-fixing but non-nodulating isolate from Morella californica, was established on the basis of a polyphasic approach. The strain grows as branched hyphae, with vesicles and non-motile productive multilocular sporangia. It metabolizes short fatty acids, TCA cycle intermediates and carbohydrates as carbon sources, and fixes nitrogen in the absence of combined nitrogen source in the growth media. Chemotaxonomic traits of strain M16386T are consistent with its affiliation to the genus Frankia...

Cerium oxide nanoparticles (nanoceria) display antioxidant properties and have shown cytoprotective effects both in vitro and in vivo. Here, we explored the effects of nanoceria on neural progenitor cells using the C17.2 murine cell line as a model. First, we assessed the effects of nanoceria versus samarium (Sm) doped nanoceria on cell viability in the presence of the prooxidant, DMNQ. Both particles were taken up by cells and nanoceria, but not Sm-doped nanoceria, elicited a temporary cytoprotective effect upon exposure to DMNQ...
