Logistic regression analysis and the
Fisher exact test were used for statistical analysis. Sensitivity, specifi city, accuracy, positive and negative predictive values, and positive likelihood ratio were calculated. To assess interobserver agreement, a kappa statistic was used.
Results: The positive predictive value of surface irregularities larger than 2 mm for MR tendinopathy or a partial- or fullthickness tear was 90% (37 of 41 patients). The sensitivity of radiographic changes selleck kinase inhibitor was 40%; the specifi city, 94%; the accuracy, 61%; the negative predictive value, 49%; and the positive likelihood ratio, 5.8. Interobserver agreement for detection of trochanteric surface irregularities on conventional radiographs ranged from 0.28 to 0.76.
Conclusion: Pronounced (>2 mm) surface irregularities of the greater trochanter on conventional radiographs were associated with abductor tendon MR abnormalities. NVP-LDE225 supplier (C)RSNA, 2010″
“Paris polyphylla var. chinensis is a perennial herb with medicinal properties
that is widely used in traditional Chinese medicine. However, this plant has been on the edge of extinction during the last few decades because of excessive deforestation based on the intense ethnopharmaceutical interest. We isolated 12 microsatellite loci from a (CT)(n)-enriched genomic library of P. polyphylla var. chinensis. The polymorphism at each locus was analyzed by screening 30 individuals from a natural population. The number of alleles ranged from 2 to 5. The observed and expected heterozygosities ranged from 0.000 to 0.467, with a mean of 0.247, and from 0.383 to 0.662 with a mean of 0.537, respectively. Six loci (Pp1, Pp3, Pp6, Pp7, Pp9,
and Pp12) were found to significantly deviate from Hardy-Weinberg equilibrium. This may be due to the small population size, inbreeding or null alleles. Five of the pairwise comparisons (Pp1 and Pp4, Pp2 and Pp5, Pp2 and Pp9, Pp2 and Pp12, Pp11 and Pp12) exhibited significant linkage disequilibrium (P < 0.05). We conclude that these microsatellite markers will be useful for population genetic studies of P. polyphylla var. chinensis.”
“We investigate the AZD1390 mw electro-optic properties and high-frequency relative dielectric constants of epitaxially grown lanthanum-modified lead zirconate titanate (PLZT) and polycrystalline barium titanate (BaTiO(3)) films in a high-frequency range of up to 40 GHz for designing a high-speed ferroelectric thin-film modulator. We also demonstrate a ferroelectric thin-film Mach-Zehnder-type waveguide modulator using the epitaxially grown PLZT film. The use of a composite structure with a low dielectric coefficient substrate and a buffer layer enabled of a ferroelectric thin-film waveguide modulator with 40-Gb/s operation.
