Estimating species phylogenies using coalescence times among sequences.
The estimation of species trees (phylogenies) is one of the most important problems in evolutionary biology, and recently, there has been greater appreciation of the need to estimate species treesExpand

High-resolution species trees without concatenation
The vast majority of phylogenetic models focus on resolution of gene trees, despite the fact that phylogenies of species in which gene trees are embedded are of primary interest. We analyze aExpand

Species trees from gene trees: reconstructing Bayesian posterior distributions of a species phylogeny using estimated gene tree distributions.
The desire to infer the evolutionary history of a group of species should be more viable now that a considerable amount of multilocus molecular data is available. However, the current molecularExpand

Estimating Species Trees Using Multiple-Allele DNA Sequence Data
Abstract Several techniques, such as concatenation and consensus methods, are available for combining data from multiple loci to produce a single statement of phylogenetic relationships. However,Expand

The Major Histocompatibility Complex–related Fc Receptor for IgG (FcRn) Binds Albumin and Prolongs Its Lifespan
The inverse relationship between serum albumin concentration and its half-life suggested to early workers that albumin would be protected from a catabolic fate by a receptor-mediated mechanism muchExpand

Phylogenetic Tree Construction Using Markov Chain Monte Carlo
Abstract We describe a Bayesian method based on Markov chain simulation to study the phylogenetic relationship in a group of DNA sequences. Under simple models of mutational events, our methodExpand

Sphingosine Kinase-1 Expression Correlates With Poor Survival of Patients With Glioblastoma Multiforme: Roles of Sphingosine Kinase Isoforms in Growth of Glioblastoma Cell Lines
Sphingosine-1-phosphate is a bioactive lipid that is mitogenic for human glioma cell lines by signaling through its G protein-coupled receptors. We investigated the role of sphingosine-1-phosphateExpand

Coalescent methods for estimating phylogenetic trees.
We review recent models to estimate phylogenetic trees under the multispecies coalescent. Although the distinction between gene trees and species trees has come to the fore of phylogenetics, onlyExpand

Improving diagnostic accuracy and interobserver concordance in the classification and grading of primary gliomas
Accurate histologic diagnosis of gliomas is fundamental to proper patient management and to the interpretation of basic and clinical investigations. Diagnostic accuracy and reproducibility areExpand

Ganglioside GM1 Enhances Induction by Nerve Growth Factor of a Putative Dimer of TrkA
Abstract: GM1 enhances nerve growth factor (NGF)‐stimulated neuritogenesis and prevents apoptotic death of PC12 cells; both may be due to enhancement of TrkA dimerization. In this study, we examinedExpand
