Reconstruction of ancestral protein sequences and its applications
BMC Evolutionary Biology, 2004 Background Modern-day proteins were selected during long evolutionary history as descendants of ancient life forms. In silico reconstruction of such ancestral protein sequences facilitates our understanding of evolutionary processes, protein ...

iScience, 2023 Summary: Modern Japanese people have two major ancestral populations: indigenous Jomon hunter-gatherers and continental East Asian farmers. To determine the formation process of the current Japanese population, we developed a detection method for ...

La profondeur des souches ancestrales au Québec, une mesure de la régionalité de la population
Espace populations sociétés, 2011 The ancestral roots of a population usually refer to the paternal lines, due to the transmission of surnames from one generation to another. However, paternal lines reach only a portion of the ancestors, whose relative importance diminishes as we go back

A PCA-based method for ancestral informative markers selection in structured populations [PDF]
Science in China Series C: Life Sciences, 2009 Identification of population structure can help trace population histories and identify disease genes. Structured association (SA) is a commonly used approach for population structure identification and association mapping. A major issue with SA is that its performance greatly depends on the informativeness and the numbers of ancestral informative ...

PLoS ONE, 2013 The bacterial genomes of Thermotoga species show evidence of significant interdomain horizontal gene transfer from the Archaea. Members of this genus acquired many genes from the Thermococcales, which grow at higher temperatures than Thermotoga species ...

A new method of inference of ancestral nucleotide and amino acid sequences. [PDF]
Genetics, 1995 Abstract A statistical method was developed for reconstructing the nucleotide or amino acid sequences of extinct ancestors, given the phylogeny and sequences of the extant species. A model of nucleotide or amino acid substitution was employed to analyze data of the present-day sequences, and maximum likelihood estimates of parameters ...

Greedy selection of species for ancestral state reconstruction on phylogenies: elimination is better than insertion. [PDF]
PLoS ONE, 2010 Accurate reconstruction of ancestral character states on a phylogeny is crucial in many genomics studies. We study how to select species to achieve the best reconstruction of ancestral character states on a phylogeny.

Pediatric Blood &Cancer, EarlyView.ABSTRACT The medical burdens of sickle cell disease (SCD) and transfusion‐dependent β‐thalassemia (TDT) are chronic and cumulative, even in children. Yet the effects expand beyond medications and healthcare visits due to their impacts on school attendance, academic performance, and peer engagement.
