1. Diagnosis accuracy of PCA3 level in patients with prostate cancer: a systematic review with meta-analysis
ABSTRACT Background: The diagnostic value and suitability of prostate cancer antigen 3 (PCA3) for the detection of prostate cancer (PCa) have been inconsistent in previous studies. Thus, the aim of the present meta-analysis was performed to systematically evaluate the diagnostic value of PCA3 for PCa. Materials and Methods: A meta-analysis was performed to

2. Verificação da previsão do tempo em São Paulo com o modelo operacional WRF / Review of weather in São Paulo with the WRF Operational Model.
Forecasts of daily maximum and minimum temperatures and rainfall performed by the operational numerical weather prediction WRF (Weather Research Forecasting) model in the São Paulo are evaluated. Initial and boundary conditions provided by the 00UTC Global Forecast System (GFS) Model and WRF run for 72 hours, with two nested grids (with horizontal grid spac

3. Modelos lineares mistos em dados longitudionais com o uso do pacote ASReml-R / Linear Mixed Models with longitudinal data using ASReml-R package
Currently, most part of the experiments installed is designed to be carried out observations over time or at different depths. These experiments usually have a longitudinal factor. One way of analyzing this data set is by using mixed models through means of inclusion of random effect factors, and it is possible to estimate the variance components associated

5. Evaluation of statistical methods applied to diagnostics tests in the presence of the verification bias. / Avaliação de métodos estatísticos aplicados ao estudo de testes diagnósticos na presença do viés de verificação
O estudo de métodos estatísticos na avaliação de métodos diagnósticos tem aumentado consideravelmente nas últimas décadas. Desde o início, quando Yerushalmy (1947) publicou seu traba lho sobre confiabilidade do roentgeno grama na identificação da tuberculose, novas metodologias surgiram para que fosse possível a obtenção de valores de sensibili

8. NotI flanking sequences: a tool for gene discovery and verification of the human genome
A set of 22 551 unique human NotI flanking sequences (16.2 Mb) was generated. More than 40% of the set had regions with significant similarity to known proteins and expressed sequences. The data demonstrate that regions flanking NotI sites are less likely to form nucleosomes efficiently and resemble promoter regions. The draft human genome sequence contained
