Virologic versus cytologic triage of women with equivocal Pap smears: a meta-analysis of the accuracy to detect high-grade intraepithelial neoplasia.
ASCUS or worse was 81.8% (95% CI = 73.5% to 84.3%) and 57.6% (95% CI = 49.5% to 65.7%), respectively. Repeat cytology that used higher cytologic thresholds yielded substantially lower sensitivity but ...
Decision support tools for clinical diagnosis of disease in cows with suspected bovine spongiform encephalopathy.
movement or carriage, increased alertness behavior, reduced milk yield, teeth grinding, and temperament change. Ataxia did not appear to be a specific sign of BSE. A classification and regression tree was ...
Estimation of the minimum detectable value for the determination of PCBs in fatty food samples by GC-ECD: a curvilinear calibration case
p.413- 418 (2003) Keywords: alternatives at Calibration Case estimation food Impact IS method methods MODEL models ON PCB Pcbs RANGE regression Regression model result results Sample Samples Yield ...
Metaanalysis of the accuracy of rapid prescreening relative to full screening of pap smears.
detected only by RPS (2.8%; CI 0.0-5.8%). This is comparable to the proportion of false-negative smears detectable by RR. CONCLUSIONS: Rapid prescreening has a high yield for severe dysplasia and shows ...
Linearity of calibration curves: use and misuse of the correlation coefficient
Statistical Test tests use VALIDATION values variables Yield Abstract: The correlation coefficient is commonly used to evaluate the degree of linear association between two variables. However, it can be shown ...
First evidence of Johne's disease in farmed red deer (Cervus elaphus) in Belgium.
the intestine. Although Ziehl-Neelsen staining yielded no positive results, a catarrhal focal necrotic enteritis associated with a granulomatous lymphadenitis compatible with Johne’s disease was ...
Comparison of biological activities of natural and recombinant chicken interferon-gamma.
obtained in the supernatants of infected insect cells. On the other hand, yields of the E. coli produced ChIFN-gamma rarely exceeded 100 microg/ml after purification steps and although it was also able to ...
Optimization of an antibiotic residue screening test, based on inhibition of Bacillus subtilis BGA, with experimental design
groups were measured. An optimized multi-residue test was established with the parameter values that yielded the best sensitivity for the four substances Service: Geneesmiddelen en gezondheidsproducten ...

Isolation of yeasts from bovine milk in Belgium
positive. Normal milk yielded not less than 16 different species and among them many potentially pathogenic yeast species such as C. parapsilosis, C. guilliermondii, C. tropicalis, C. glabrata and T. asahii, ...
