We present a modified GPU (graphics processing unit) version of MrBayes, called ta(MC)(3) (GPU MrBayes V3.1), for Bayesian phylogenetic inference on protein data sets. Our main contributions are 1) utilizing 64-bit variables, thereby enabling ta(MC)(3) to process larger data sets than MrBayes; and 2) to use Kahan summation to improve accuracy, convergence(More)
OBJECTIVE To investigate the apoptosis induction effect of vitamin E succinate (VES) on Tca8113 cells and its possible mechanisms. METHODS The proliferative activity of Tca8113 was assessed by methyl thiazolyl tetrazolium (MTT) assay. After Tca8113 cells were treated with different concentrations of VES, apoptotic rates were analyzed by flow cytometry(More)
OBJECTIVE To detective the relationship between cyclooxygenase-2 (COX-2) and angiogenesis in oral squamous cell carcinoma (OSCC) and its clinical significance through observing the expression of COX-2 and determining microvessel density (MVD) in OSCC. METHODS PV-9000 immunohistochemistry was used to determine the expression of COX-2 and CD34, which was(More)
Insecta s. str. (=Ectognatha), comprise the largest and most diversified group of living organisms, accounting for roughly half of the biodiversity on Earth. Understanding insect relationships and the specific time intervals for their episodes of radiation and extinction are critical to any comprehensive perspective on evolutionary events. Although some(More)
With the great development of sequencing technologies and systematic methods, our understanding of evolutionary relationships at deeper levels within the tree of life has greatly improved over the last decade. However, the current taxonomic methodology is insufficient to describe the growing levels of diversity in both a standardised and general way due to(More)
