It decreases with increasing atomic ionization energy. For the case of Cs-deposition, the 2D electron density and mobility are studied over a wide coverage range. A clear increase in electron mobility appears above half monolayer coverage. For a surface covered with a submonolayer of Fe, hysteresis in the magnetoresistance is observed. It is associated with spin-glass ordering in the Fe film. (C) 2011 American Institute of Physics. [doi :10.1063/1.3578263]“
“During the screening of anti-influenza virus substances from traditional herbal medicines, Geneticin supplier the methanol extract from the leaves of Pogostemon cablin Benth. showed potent in vitro antiviral activity (99.8% inhibition
at a concentration of 10 mu g/mL) against influenza virus A/PR/8/34 (H1N1). The anti-influenza virus principle was isolated LB-100 from the hexane-soluble fraction, through solvent fractionation, repeated silica gel column chromatography, and reversed-phase HPLC. The major active principle
was a volatile substance that was identified as a sesquiterpene, patchouli alcohol (1), on the basis of its spectral analyses. When anti-influenza virus activity against A/PR/8/34 was evaluated by the plaque forming assay, patchouli alcohol reduced the number of plaques by 75% at 2 mu g/mL and 89% at 10 mu g/mL. Patchouli alcohol showed dose-dependent anti-influenza virus activity, and its IC(50) value was estimated to be 2.635 mu M. Although 11 different sesquiterpenes were tested for antiviral activity against influenza virus A/PR/8/34, no or negligible activity was observed except for patchouli alcohol. Patchouli alcohol did not show anti-influenza virus activity against A/Guizhou/54/89
(H3N2), but showed weak activity against B/Ibaraki/2/85 (IC(50) = 40.82 mu M). Patchouli alcohol did not show inhibitory activity against influenza virus neuraminidase.”
“Aims: Cytoskeletal Signaling inhibitor Intensity-modulated radiotherapy (IMRT) is a development of three-dimensional conformal radiotherapy that offers improvements in dosimetry in many clinical scenarios. Here we review the clinical evidence for IMRT and present ongoing or unpublished randomised controlled trials (RCTs).
Methods: We identified randomised and non-randomised comparative studies of IMRT and conventional radiotherapy using MEDLINE, hand-searching Radiotherapy and Oncology and the International Journal of Radiation Oncology, Biology and Physics and the proceedings of the American Society for Therapeutic Radiology and Oncology and the European Society for Therapeutic Radiology and Oncology annual meetings. The metaRegister of Controlled Trials was searched to identify completed-unpublished, ongoing and planned RCTs.
Results: Sixty-one studies comparing IMRT and conventional radiotherapy were identified.
