BACKGROUND In western North America, plague epizootics caused by Yersinia pestis appear to sweep across landscapes, primarily infecting and killing rodents, especially ground squirrels and prairie dogs. During these epizootics, the risk of Y. pestis transmission to humans is highest. While empirical models that include climatic conditions and densities of rodent hosts and fleas can predict when...

Science 2008; 319: 91–93. 3 Lemos B, Branco AT, Hartl DL. Epigenetic eff ects of polymorphic Y chromosomes modulate chromatin components, immune response, and sexual confl ict. Proc Natl Acad Sci USA 2010; 107: 15826–31. 4 Spach ...
We performed extensive and realistic simulations of the colonization process of Europe by Neolithic farmers, as well as their potential admixture and competition with local Palaeolithic hunter-gatherers. We find that minute amounts of gene flow between Palaeolithic and Neolithic populations should lead to a massive Palaeolithic contribution to the current gene pool of Europeans. This large Pala...
an important part of plant in vitro techniques is the sterilization of explants and the maintenance of aseptic conditions. ideally, sterilizing materials should be effective on a vast range of microorganisms at low density. nowadays, the use of compounds such as essential oils (eos) and nanoparticles is applicable in microbiology studies. the main objective of this experiment was to study the s...
DNA samples from 307 males of 13 Portuguese native cattle breeds, 57 males of the 3 major exotic breeds in Portugal (Charolais, Friesian, and Limousin), and 5 Brahman (Bos indicus) were tested for 5 single nucleotide polymorphisms, 1 "indel," and 7 microsatellites specific to the Y chromosome. The 13 Y-haplotypes defined included 3 previously described patrilines (Y1, Y2, and Y3) and 10 new hap...
Introduction: Silver nanoparticles (SNPs) have recently been suggested to increase the antimicrobial properties of soft liner materials. However, their safety remains a matter of debate. This study aimed to evaluate the cytotoxicity of Mucopren® soft silicone liner material (Mucopren; Kettenbach, Germany) incorporated in SNPs. Methods: The SNPs with ...
Though the Y-chromosome O2a-M95 lineage is one of the major haplogroups present in eastern Asian populations, especially among Austro-Asiatic speaking populations from Southwestern China and mainland Southeast Asia, to date its phylogeny lacks structure due to only one downstream SNP marker (M88) assigned to the lineage. A recent array-capture-based Y chromosome sequencing of Asian samples has ...
BACKGROUND Genome-wide association (GWA) studies regarding the quantitative trait of alcohol consumption are limited. OBJECTIVE The objective of the study was to explore genetic loci associated with the amount of alcohol consumed. DESIGN We conducted a GWA study with discovery data on single nucleotide polymorphisms (SNPs) for 1721 Korean male drinkers aged 40-69 y who were included in an u...
