ROC curve analysis is often applied to measure the diagnostic accuracy of a biomarker. The analysis results in two gains: diagnostic accuracy of the biomarker and the optimal cut-point value. There are many methods proposed in the literature to obtain the optimal cut-point value. In this study, a new approach, alternative to these methods, is proposed. The proposed approach is based on the valu...

Purpose This study evaluated the cytokine levels in unilateral tear samples from both sides in patients with pediatric lacrimal duct obstruction. Methods Fifteen cases of unilateral lacrimal duct obstruction (mean, 26.9 ± 28.7 months old) were enrolled in this study. Tear samples were collected separately from the obstructed side and the intact side in each case before surgery, which was perf...

PURPOSE Prostate biopsy is used to confirm the prostate cancer. Although first biopsy result was benign, repeat biopsy is recommended for the patient who has higher risk of prostate cancer. In this study, we investigated the PSA change ratio (post-biopsy PSA to baseline PSA) whether it could be predictive factor of prostate cancer and helpful when decided to perform repeat biopsy. MATERIALS A...

Subject (73 y/o male) with right internal carotid arterial stenosis = 15% seen on the CE MRA MIP (right side); while hemorrhage (arrow) and ruptured fibrous cap (arrowhead) were identified on the TOF and T1W images. Four continuous cross-sectional images are...

OBJECTIVE The aim of this study is to assess the efficacy of cervical interleukin-6 (IL-6) compared with cervical length and its association in the prediction of preterm delivery in symptomatic women. STUDY DESIGN Observational prospective study was performed at Hospital Universitario La Fe, Valencia (Spain). SAMPLE 100 women between 24 and 34 weeks gestational age, with threatened preterm ...

BACKGROUND To compare the diagnostic accuracy of two continuous screening tests, a common approach is to test the difference between the areas under the receiver operating characteristic (ROC) curves. After study participants are screened with both screening tests, the disease status is determined as accurately as possible, either by an invasive, sensitive and specific secondary test, or by a l...

Material and Method : A prospective study of analysis of 100 cases (50 ascites and 50 pleural fluids) was carried out over a period of 6 months. In all these cases, clinical diagnosis was established after clinical examination and appropriate investigations. The fluid and serum levels of protein, albumin, LDH and cholesterol were determined and various ratios were obtained. The statistical anal...

The issue of credit risk and deferred bank claims is one of the sensitive issues of banking industry, which can be considered as the main cause of bank failures. In recent years, the economic slowdown accompanied by inflation in Iran has led to an increase in deferred bank claims that could put the country's banking system in serious trouble. Accordingly, the current paper presents a prediction...

Category Theory is used to describe a category of fusors. The category is formed from a model of a process begining with an event and leading to the final labeling of the event. Although many techniques of fusing information have been developed the inherent relationships among different types of fusion techniques (fusors) have not yet been fully explored. In this paper, a foundation of fusion i...
