We determined Pearson correlation coefficients between
the reference standard and the three other methods for lobar volumes and emphysematous lobar volumes. We also compared the relative errors among the three measurement methods.
RESULTS: Both semi-automatic and automatic computer-aided diagnosis results were more strongly correlated with the reference standard than the number of segments method. The correlation coefficients for automatic computer-aided diagnosis were slightly lower than those for semi-automatic computer-aided diagnosis because there was one outlier among 50 cases (2%) in the right upper lobe and two outliers among 50 cases (4%) in the other lobes. The number of segments method relative error was significantly greater than those for semi-automatic and automatic computer-aided diagnosis (P < 0.001). The computational time for automatic computer-aided diagnosis was 1/2 to Torin 2 mouse 2/3 than that of semi-automatic computer-aided diagnosis.
CONCLUSIONS: A novel lobar volumetry computer-aided diagnosis system could more precisely measure lobar volumes than the conventional number of segments method. Because semi-automatic computer-aided
diagnosis and automatic computer-aided diagnosis were complementary, in clinical use, it would be more practical to first measure volumes by automatic computer-aided diagnosis, and then use semi-automatic measurements if automatic computer-aided diagnosis failed.”
“Cytotoxicity and antioxidant properties of the methanol Mdm2 inhibitor extracts of leaves and flowers of Cornus mas and Cotinus coggygria were studied, together with their chemical composition. Extracts of C. coggygria flowers and leaves showed better antioxidant activity in reaction with 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical as well as in inhibition selleck chemical of lipid peroxidation (LP) than C. mas extracts. Preliminary
results showed that all extracts possessed potential cytotoxic activity towards HeLa and LS174 human cancer cell lines in vitro, with stronger inhibition against growth of HeLa cell growth than against LS174 cell growth. Cytotoxic activity of C. coggygria extracts showed good correlation with their antioxidative activity in vitro. In the brine shrimp lethality test, there were no significant changes in toxicity.”
“Objective To determine the clinical and histologic effects of diode endoscopic cyclophotocoagulation (ECP) in the phakic equine eye. Animals studied Phase I: 10 equine cadaver eyes. Phase II: four normal adult horses. Procedures Phase I: ECP probe angle of reach (AR) was determined. Multiple ECP energy levels: 0.75, 0.90, 1.05, 1.20, 1.35, 1.50J, and the resulting visible and histologic ciliary process changes were evaluated. Phase II: Ocular quadrants were treated with ECP at 0.90, 1.14, 1.
