Phylogeny and evolution of infectious bursal disease virus circulating in Turkish broiler flocks
The emergence of new infectious bursal disease virus (IBDV) variants can threaten poultry health and production all over the world causing significant economic losses. Therefore, this study was performed to determine IBDV molecular epidemilogy, VP2 gene variation, and corresponding pathological lesions in IBDV infected chickens in Turkey. For this, 1855 bursa of Fabricius samples were collected from 371 vaccinated broiler flocks. Atrophia and haemorrhages were seen in the bursa Fabricius of very virulent IBDV (vvIBDV) infected chickens. Partial VP2 gene was sequenced and phylogenetic, recombination, and evolutionary analyses were performed. 1548 (83.5%) out of 1855 of bursa of Fabricius samples were IBDV positive and 1525 of those could be sequenced. The recombination analysis did not detect occurrence of any recombination event among the Turkish strains. Among 1525 sequenced samples, 1380 of them were found to be classical strains. Among 1380 classical strains, 1317 were similar to IBDV 2512, 11 to Faragher 52/70, 40 to 228 E, and 12 to Lukert strain. Out of 1525 reverse transcriptase ploymerase chain reaction positive samples, 144 of them were found to be similar to vvIBDV-VP2 gene reported to GenBank previously. The phylogenetic tree performed on a broad sequence dataset demonstrated grouping of vvIBDV Turkish strains in three different clusters, including sequences collected also from Iraq and Kuwait (Cluster 1), Indian (Cluster 2), and a distinct Turkish-only cluster (Cluster 3). The evolutionary rate estimation on branches/clades including Turkish strain mirrored the expected one for RNA viruses and no significant differences were found among different considered branches. In conclusion, results of this study indicate that vvIBDV strains similar to those circulating in various countries in the Middle East are present and undergoing evolution in chickens from Turkish broiler flocks. This point needs to be taken into account in planning adequate control strategies
Carbon-Coated SnO2 Nanorod Array for Lithium-Ion Battery Anode Material
Carbon-coated SnO2 nanorod array directly grown on the substrate has been prepared by a two-step hydrothermal method for anode material of lithium-ion batteries (LIBs). The structural, morphological and electrochemical properties were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and electrochemical measurement. When used as anodes for LIBs with high current density, as-obtained array reveals excellent cycling stability and rate capability. This straightforward approach can be extended to the synthesis of other carbon-coated metal oxides for application of LIBs
Low dimensional nanostructures of fast ion conducting lithium nitride
As the only stable binary compound formed between an alkali metal and nitrogen, lithium nitride possesses remarkable properties and is a model material for energy applications involving the transport of lithium ions. Following a materials design principle drawn from broad structural analogies to hexagonal graphene and boron nitride, we demonstrate that such low dimensional structures can also be formed from an s-block element and nitrogen. Both one- and two-dimensional nanostructures of lithium nitride, Li3N, can be grown despite the absence of an equivalent van der Waals gap. Lithium-ion diffusion is enhanced compared to the bulk compound, yielding materials with exceptional ionic mobility. Li3N demonstrates the conceptual assembly of ionic inorganic nanostructures from monolayers without the requirement of a van der Waals gap. Computational studies reveal an electronic structure mediated by the number of Li-N layers, with a transition from a bulk narrow-bandgap semiconductor to a metal at the nanoscale

Postoperative Radiotherapy in the Management of Resected Non-Small-Cell Lung Carcinoma: 10 Years' Experience in a Single Institute
PubMed ID: 19386425Purpose: This study reports the long term outcomes of postoperative radiotherapy in patients with resection for non-small-cell lung cancer (NSCLC). Methods and Materials: A total of 98 patients with resected NSCLC who received postoperative radiotherapy (PORT) between January 1994 and December 2004 were retrospectively analyzed. The most frequently performed surgical procedure was lobectomy (59 patients), followed by pneumonectomy (25), wedge resection (8), and bilobectomy (6). Postoperative radiotherapy was delivered as an adjuvant treatment in 71 patients, after a wedge resection in 8 patients, and after an R1 resection in 19 patients. The PORT was administered using a Co-60 source in 86 patients and 6-MV photons in 12 patients. A Kaplan-Meier estimate of overall survival, locoregional control, and distant metastasis-free survival were calculated. Results: Stages included I (n =13), II (n = 50), IIIA (n = 29), and IIIB (n = 6). After a median follow-up of 52 months median survival was 61 months. The 5-year overall survival, locoregional control, and distant metastasis-free survival rates for the whole group were 50%, 78%, and 55% respectively. The RT dose, Karnofsky performance status, age, lateralization of the tumor, and pneumonectomy were independent prognostic factors for OAS; anemia and the number of involved lymph nodes were independent prognostic factors for LC. Conclusions: Doses of PORT of greater than 54 Gy were associated with higher death rate in patients with left-sided tumor, which may indicate a risk of radiation-induced cardiac mortality. © 2010 Elsevier Inc
