plenty of heterogeneous biological datasets were integrated in WBSMDA, including known miRNA-disease associations, miRNA functional similarity network, disease semantic similarity network, and Gaussian interaction profile kernel similarity, which benefit the improvement of prediction accuracy and decrease the pr...
The Sciex API100 LC/MS (Liquid Chromatography/Mass Spectrometer) mass spectrometer (Massachusetts, USA) was used to confirm the molecular weight and sequence accuracy of the peptides. MTT assay In a 96-well plate, 5 × 103 cell/well MDA-MB 231 and 104 cell/well MCF-10A cells were ...
These biological experimental methods usually have high prediction accuracy; nevertheless, their processes are complex, expensive, and time-consuming (Liang et al., 2019). To this end, to accelerate the verification process, and reduce the time consumption and blindness of biological experiments, it ...
The accuracy figure stood at 76%, while the sensitivity was 60% and specificity reached 867%. Predictions of p53 mutations based on immunohistochemistry (IHC) using this specific antibody may be inaccurate in up to 25% of cases. European wild boar (Sus scrofa), a remarkably abundant game ...
Studies with breast cell lines, showing that 5α-pregnanes stimulate proliferation and decrease attachment of cells [1, 2] prompted us to suggest that neoplasia in human breast may be promoted by increases in ratio of 5α-pregnanes:4-pregnenes. In the current studies, the ratio of 5α-...
