02). Patients with CF had moderate lung disease with a mean Bhalla score of 9.2 +/- 5.3 (range, 0-19), compared with that of patients without CF (1.1 +/- 1.4; P < .001). There was excellent correlation between thin-section CT and chest radiography

(r = 0.88-0.92; P < .001).

Conclusion: Low-dose thin-section CT can be performed at lower effective doses than can standard CT, approaching those of chest radiography. Low-dose thin-section CT could be appropriate for evaluating bronchiectasis in pediatric patients, Ricolinostat inhibitor yielding appropriate information about lung parenchyma and bronchovascular structures.

“Photoreflectance spectroscopy and photoluminescence (PL) have been used to explore the optical properties and electronic structure of InGaAs quantum rods (QRs) grown by molecular beam epitaxy. Different As sources – As-2 and As-4 – were used during epitaxial

growth in order to evaluate their effect on the optical properties of the nanostructures. Spectral features associated with interband optical transitions taking place in the QR and the surrounding quantum well (QW) regions are examined. A redshift of the QR- and a blueshift of the QW-related optical transitions, along DMH1 with a significant increase in PL intensity, have been observed if an As-4 source is used. These changes in optical properties are mainly attributed to quantum confinement effects related to a variation of indium content

in the QR and QW regions. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3599888]“
“Corynebacterium pseudotuberculosis, the infectious agent of caseous lymphadenitis (CLA), is responsible for substantial economic losses in goat and sheep production. Molecular characterization of C. pseudotuberculosis isolates by enterobacterial repetitive intergenic consensus (ERIC)-PCR has shown promising results in genotyping strains isolated from sheep with CLA. We evaluated the genetic diversity of C. pseudotuberculosis isolates collected from the Sertao region of the Pernambuco (PE) State, Brazil, and investigated the potential of selleckchem ERIC-PCR as a tool for the molecular typing of strains of C. pseudotuberculosis isolated from goats. Thirty-two C. pseudotuberculosis strains isolated from goats in the municipalities of Floresta and Ibimirim, PE, C. pseudotuberculosis type strain ATCC 19410, the 1002 vaccine strain, and a field isolate of Rhodococcus equi were fingerprinted using the primers ERIC-1R and ERIC-2 and the primer pair ERIC-1R+ERIC-2. Using 100% similarity as the cutoff, 8, 10, and 7 genotypes were obtained with ERIC-1-PCR, ERIC-2-PCR, and ERIC-1+2-PCR, respectively. The Hunter-Gaston discriminatory index calculated for the ERIC-1-PCR was 0.75. The index for the ERIC-2-PCR was 0.88, and the index for the ERIC-1+2-PCR was 0.79. Among goat isolates of C.
