Genomic insights into the genetic structure and population history of Mongolians in Liaoning Province

Frontiers in Genetics, 2022
The Mongolian population exceeds six million and is the largest population among the Mongolic speakers in China. However, the genetic structure and admixture history of the Mongolians are still unclear due to the limited number of samples and lower ...

Genomic variation in a widespread Neotropical bird (Xenops minutus) reveals divergence, population expansion, and gene flow [PDF]

, 2014
Elucidating the demographic and phylogeographic histories of species provides insight into the processes responsible for generating biological diversity, and genomic datasets are now permitting the estimation of histories and demographic parameters with ...

Response: genetic admixture in sickle cell disease

Blood, 2011
Genetic studies require careful thought about ancestry in the study design and analysis to avoid population stratification bias and to maximize the power of finding novel variants.1 If both the genetic marker and the phenotype vary with respect to ancestry, then a spurious association will occur between the genetic marker and phenotype if one does not ...

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

Advanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Estimating the timing of multiple admixture events using 3-locus linkage disequilibrium.

PLoS Genetics, 2022
Estimating admixture histories is crucial for understanding the genetic diversity we see in present-day populations. Allele frequency or phylogeny-based methods are excellent for inferring the existence of admixture or its proportions.

Massive migration from the steppe is a source for Indo-European languages in Europe

, 2015
We generated genome-wide data from 69 Europeans who lived between 8,000-3,000 years ago by enriching ancient DNA libraries for a target set of almost four hundred thousand polymorphisms. Enrichment of these positions decreases the sequencing required for

Admixture Mapping of Diabetic Nephropathy Genetic Variants

The FASEB Journal, 2018
The goal of our research study is to identify diabetes dependent genetic variants that confer susceptibility or resistance to the development of kidney disease. It is thought, based on previous studies, that the susceptibility is associated with African ancestry.

Unidirectional Tape‐Based Composites from Hemp and Pineapple Leaf Fiber: Mechanical Performance in Conventional and Bio‐Based Matrices

Advanced Engineering Materials, EarlyView.
The study investigates novel semi‐finished products made of unidirectionally arranged hemp or pineapple leaf fiber‐reinforced composites produced from different matrices. The materials are analyzed in terms of their mechanical and interfacial properties and void content.
