We evaluated the feasibility of resazurin microtiter assay (REMA) for detecting cycloserine resistance of Mycobacterium tuberculosis. The cutoff value of the critical concentration of cycloserine resistance in vitro about M. tuberculosis isolates was determined innovatively by drawing the receiver operating characteristic (ROC) curve for the first time. The spending time of REMA ranged from 6 t...

ABSTRACT Receiver operating characteristics (ROC) curve with the calculation of area under curve (AUC) is a useful tool to evaluate the performance of biomedical and chemoinformatics data. For example, in virtual drug screening ROC curves are very often used to visualize the efficiency of the used application to separate active ligands from inactive molecules. Unfortunately, most of the availab...

We show that any weak ranker that can achieve an area under the ROC curve slightly better than 1/2 (which can be achieved by random guessing) can be efficiently boosted to achieve an area under the ROC curve arbitrarily close to 1. We further show that this boosting can be performed even in the presence of independent misclassification noise, given access to a noise-tolerant weak ranker.

Background: When developed in 1981 by Moore and colleagues the Penetrating Abdominal Trauma Index (PATI) was used to identify trauma patients at risk of postoperative complications. Methods of trauma quantification have been extensively developed but their outcome evaluations have been naïve, subject only to basic statistical analyses. The accuracy of PATI was assessed by means of Receiver Oper...

abstract background: recent studies have suggested that oxidative stress (os) may have a contribution in the pathogenesis of endometriosis. however, the results of previous studies regarding os in endometriosis are controversial. the objective of this study was to compare the serum levels of os markers in endometriosis versus the control group. methods: this case-control study was carried out o...

This prospective study assessed whether respiratory variations in velocity time integral, peak blood flow velocity and non-invasive pleth variability index are useful measurements in infants undergoing congenital heart surgery and determined threshold values that may help guide fluid administration. In 27 infants receiving mechanical ventilation, of mean (SD) weight 10.4 (6.3) kg, 13 increased ...
