European population history has been shaped by migrations of people, and their subsequent admixture. Recently, ancient DNA has brought new insights into European migration events linked to the advent of agriculture, and possibly to the spread of Indo-European languages. However, little is known about the ancient population history of north-eastern Europe, in particular about populations speaking Uralic languages, such as Finns and Saami. Here we analyse ancient genomic data from 11 individuals from Finland and north-western Russia. We show that the genetic makeup of northern Europe was shaped by migrations from Siberia that began at least 3500 years ago. This Siberian ancestry was subsequently admixed into many modern populations in the region, particularly into populations speaking Uralic languages today. Additionally, we show that ancestors of modern Saami inhabited a larger territory during the Iron Age, which adds to the historical and linguistic information about the population history of Finland.

Background: The widespread selective pressure of antibiotics in the environment has led to the propagation of antibiotic resistance genes (ARGs). However, the mechanisms by which microbes balance population growth with the enrichment of ARGs remain poorly understood. To address this, we employed microcosm cultivation at different antibiotic (i.

Background: Greater therapeutic alliance has been associated with an improved treatment outcome in various clinical populations. However, there is a lack of evidence for this association in posttraumatic stress disorder (PTSD) in young patients. We therefore investigated the development of the therapeutic alliance during Developmentally adapted cognitive processing therapy (D-CPT) in adolescents and young adults with PTSD following abuse to answer the question whether there was a connection between the therapeutic alliance and symptom reduction.

Introduction: Despite many studies on the prevalence of vertebral fractures (VFs), the VF prevalence at death in the Japanese population remains unclear.
Materials And Methods: We evaluated the VF prevalence at death in a Japanese cohort using autopsy imaging computed tomography (AiCT). We enrolled 365 cadavers (188 men, 177 women, mean age of 84.

Black-bone silky fowls(Gallus gallus domesticus) have a long history of medicinal use, with the origin in Taihe county, Jiangxi province. The unclear family composition, inbreeding rate, and effective population size were inconducive to the resource conservation or breed improvement of black-bone silky fowls. A genome-wide analysis was performed to evaluate the genetic diversity of 80 black-bone silky fowls from random mating in three farms in 2021 in terms of minor allele frequency(MAF), expected heterozygosity(H_e), observed heterozygosity(H_o), effective population size(N_e), and runs of homozygosity(ROH).

Objective: To assess the role of occupational noise exposure on pregnancy complications in urban Nordic populations.
Methods: A study population covering five metropolitan areas in Denmark, Finland, Norway and Sweden was generated using national birth registries linked with occupational and residential environmental exposures and sociodemographic variables. The data covered all pregnancies during 5-11 year periods in 2004‒2016, resulting in 373 184 pregnancies.
