Ancestry informative markers and selected single nucleotide polymorphisms in immunoregulatory genes on preterm labor and preterm premature rupture of membranes: A case control study
(2016-02-05)
Background: A genetic predisposition to Preterm Labor (PTL) and Preterm Premature Rupture of Membranes (PPROM) has been suggested; however the relevance of polymorphisms and ancestry to susceptibility to PTL and PPROM in ...
Locus-specific ancestry to detect recent response to selection in admixed Swiss Fleckvieh cattle
(2016-12-01)
Identification of selection signatures is one of the current endeavors of evolutionary genetics. Admixed populations may be used to infer post-admixture selection. We calculated local ancestry for Swiss Fleckvieh, a composite ...
Obesity, genomic ancestry, and socioeconomic variables in Latin American mestizos
(Wiley, 2019)
OBJECTIVES: This article aims to assess the contribution of genomic ancestry and socioeconomic status to obesity in a sample of admixed Latin Americans. METHODS: The study comprised 6776 adult volunteers from Brazil, Chile, ...
The phylogeographic diversity of EBV and admixed ancestry in the americas–another model of disrupted human-pathogen co-evolution
(MDPI AG, 2019)
Epstein-Barr virus (EBV) is an etiological agent for gastric cancer with significant worldwide variations. Molecular characterizations of EBV have shown phylogeographical variations among healthy populations and in ...
Andean high-altitude ancestry does not protect from acute mountain sickness and altitude-induced arterial hypoxemia
(Interciencia Association, 2017)
It is thought that adaptive changes protect high-altitude populations against altitude-induced diseases, but information from well controlled studies is lacking. In a prospective, controlled study, we assessed the prevalence ...

Epstein-Barr virus (EBV) is an etiological agent for gastric cancer with significant worldwide variations. Molecular characterizations of EBV have shown phylogeographical variations among healthy populations and in ...
Subtypes of Native American ancestry and leading causes of death: Mapuche ancestry-specific associations with gallbladder cancer risk in Chile
(Public Library of Science, 2017)
Latin Americans are highly heterogeneous regarding the type of Native American ancestry. Consideration of specific associations with common diseases may lead to substantial advances in unraveling of disease etiology and ...
Maternal oxygen delivery is not related to altitude- and ancestry-associated differences in human fetal growth
(J Physiol, 2007-09-16)
Fetal growth is reduced at high altitude, but the decrease is less among long-resident populations.
We hypothesized that greater maternal uteroplacental O2 delivery would explain increased
fetal growth in Andean natives ...
