Objective: (1) To estimate the life-time genetic contribution for knee osteoarthritis (OA) surgery and (2) to explore any differences in the genetic contribution across age, sex and body mass index (BMI). Methods: We studied the sex-specific genetic contribution to knee OA surgery in a prospective cohort study of 62,490 twins aged 35 years or older with a follow-up period of up to 47 years (10,092
Neural crest cells have broad migratory and differentiative ability that differs according to their axial level of origin. However, their transient nature has limited understanding of their stem cell and self-renewal properties. While an in vitro culture method has made it possible to maintain cranial neural crest cells as self-renewing multipotent crestospheres (Kerosuo et al., 2015), these same

The conversion factor αCO from the observable CO(1-0) luminosity to the mass of molecular gas is known to vary between isolated galaxies and some mergers, but the underlying reasons are not clearly understood. Thus, the value(s) of αCO that are to be adopted remain highly uncertain. To provide better constraints, we applied the large velocity gradient method to a series of hydrodynamical simulatio
Macropores formed by roots are crucial channels for preferential flows in forest soils that are largely responsible for water percolation and solute leaching. Using dual-tracer experiments (Brilliant Blue FCF and bromide [Br]), this study investigated the preferential flows of water and solutes in a deciduous forest dominated by Bl. and a coniferous forest mainly planted with (L.) Franco. Dye-stai
We report an improved separation method for the isolation of sperm cells from dilute, "large volume" samples containing female DNA using bead-assisted acoustic trapping. In an enclosed glass-PDMS-glass (GPG) resonator, we exploit a three-layer microfluidic architecture to generate "trapping nodes" in ultrasonic standing waves. We investigate the dependence of trapping efficiency on particle concen
A mononuclear iron(II) complex [FeII(N4PyMe2)(OTf)](OTf)(1), supported by a new pentadentate ligand, bis(6-methylpyridin-2-yl)-N,N-bis((pyridin-2-yl)methyl)methanamine (N4PyMe2), has been isolated and characterized. Introduction of methyl groups in the 6-position of two pyridine rings makes the N4PyMe2 a weaker field ligand compared to the parent N4Py ligand. Complex 1 is high-spin in the solid st
We show that seven different types of commercial, biocide-free, colloidal silica products with mean particle sizes between 17 and 88 nm with 3 different surface chemistries (Na-stabilized, aluminized and silane-modified) are not toxic to the bacterium Pseudomonas putida, and the algae Raphidocelis subcapitata in the concentration range 5–500 mg/L. They are also not acutely toxic to Daphnia magna a
It has been demonstrated in animal studies that prenatal administration of β-hydroxy-β-methylbutyrate (HMB, metabolite of leucine) influences general growth and mechanical endurance of long bones in newborn offspring in sex-dependent manner. The present experiment was conducted to evaluate the effect of HMB treatment of pregnant sows on bone development in offspring at weaning. From 70th day until
Hypertension is considered the major modifiable risk factor for the development of cognitive impairment. Because increased blood pressure is often accompanied by an activation of the immune system, the concept of neuro-inflammation gained increasing attention in the field of hypertension-associated neurodegeneration. Particularly, hypertension-associated elevated circulating T-lymphocyte populatio
Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in
Aim: Perineal hemangiomas rarely occur in patients with anorectal malformations (ARMs), but they can pose a significant challenge and warrant special attention. Surgical incision of posterior sagittal anorectoplasty (PSARP) may involve the hemangioma site resulting in hemorrhage, damage to blood supply, leading to complications and adversely affecting outcome. The aim of this study was to review t
A growing body of research highlights how the Internet and social media offer new platforms for advocacy. This article contributes to the debates on digital advocacy by combining interest group and social media studies and present the notions of digital access politics, digital information politics, and digital protest politics for a comprehensive analysis of digital advocacy. Based on a netnograp
The acquisition of preverbal liaison (e.g. ils arrivent /ilzaʀiv/) in second language (L2) French has rarely been explored in detail in previous studies on obligatory liaison. In this study, we conducted an elicited imitation test in order to study the influence of proficiency level, modality (spoken or written), and verb frequency on the use of preverbal liaison among 42 Swedish learners of L2 Fr
