“The genus Nocardia includes both pathogens and producers of useful secondary metabolites. Although 16S rRNA analysis is required to accurately PD173074 concentration discriminate among phylogenetic relationships of the Nocardia species, most branches of 16S rRNA-based phylogenetic trees are not reliable. In this study, we performed in silico analyses of the genome sequences of Nocardia species in order to understand their diversity and classification for their identification and applications. Draft genome sequences of 26 Nocardia strains were determined. Phylogenetic trees were prepared on the basis of multilocus sequence analysis of the concatenated sequences of 12 genes (atpD-dnaJ-groL1-groL2-gyrB-recA-rpoA-secA-secY-sodA-trpB-ychF) and a bidirectional best hit. To elucidate the evolutionary relationships of these genes, the genome-to-genome distance was investigated on the basis of the average nucleotide identity, DNA maximal unique matches index, and genome-to-genome distance calculator. The topologies of all phylogenetic trees were found to be essentially similar to each other. Furthermore, whole genome-derived and multiple gene-derived relationships click here were

found to be suitable for extensive intra-genus assessment of the genus Nocardia.”
“Purpose\n\nTo evaluate the efficacy of single-agent vinblastine in pediatric

patients with recurrent or refractory low-grade glioma.\n\nPatients and Methods\n\nPatients were eligible if they had experienced previous treatment failure (chemotherapy and/or radiation) for incompletely resected or unresectable low-grade glioma (LGG). Vinblastine (6 mg/m(2)) was administered weekly for 1 year unless unacceptable toxicity or progression (confirmed on two consecutive imaging studies) occurred.\n\nResults\n\nFifty-one patients (age range, 1.4 to 18.2 years; median age, 7.2 years) were prospectively enrolled onto this phase II study. Fifty patients had previously received at least one prior regimen of chemotherapy, and 10 patients had previously received radiation treatment. Fifty patients were evaluable for response; 18 patients (36%) had a complete, partial, or minor response, BAY 73-4506 mw and 31 patients completed 1 year of treatment. At a median follow-up of 67 months, 23 patients had not experienced progression; three patients have died. Five-year overall survival was 93.2% +/- 3.8%, and 5-year progression-free survival was 42.3% +/- 7.2%. Toxicity was manageable and mostly hematologic, although a few patients needed transfusions.\n\nConclusion\n\nWeekly vinblastine seems to be a reasonable alternative to radiation for pediatric patients with LGG who have experienced treatment failure with first-line chemotherapy.
