The P2Et, S2Et and aqueous fractions were selected for biological testing based on their cytotoxic activity.
Finally, we investigated gene-gene interaction using a novel bioinformatics approach that restricts the number of pairwise tests based on existing biological knowledge.
The issue of designing a battery of screening tests based on the countless biological effects of growth promoters – mainly gonadal steroids, corticosteroids and β-agonists – to target the chemical analyses has been raised by several researchers (for a review, see Nebbia et al. 2011) and also by EFSA in a recent opinion on meat inspection of bovine animals (EFSA 2013).
For the enrichment of biological terms and groups, we used the two-sided (Enrichment/Depletion) tests based on the hyper-geometric distribution.
Figure 2 Statistical model analysis of the biological activity test based on glucose levels during specific times after of samples administration.
We present the results of a biological model test, based on a meta-analysis comparison between a sample pool of human CD34+ hematopoietic progenitor cells and a sample pool of megakaryocytic cells.
Since we are comparing four biological samples without replicates, a chi-square test based on normalized library size is most appropriate for differential expression analyses.
Despite many scientific advances, there are still no biological tests -- based on genes, blood markers or brain scans -- to help diagnose mental illness.
She demonstrated how biological control introductions could be manipulated and replicated, allowing hypothesis testing based on robust inference statistics.
They are researching multiple possibilities, including blood tests for chemicals and biological molecules that are released when the brain gets injured, and a new test based on the brain's communication with the muscles.
This program performs Fisher exact tests to determine biological processes (based on GO terms) that are significantly overrepresented among differentially expressed transcripts relative to the background transcriptome.
