Aim: Assess effects on waist circumference from diet with or without cereal grains and with or without long-term physical exercise. Background: Elevated waist circumference is an indicator of increased abdominal fat storage and is accordingly associated with increased cardiovascular mortality. This is likely due to the association between lifestyle-induced changes in waist circumference and cardio
Recent years have witnessed an explosion of interest in understanding the role of conformational dynamics both in the evolution of new enzymatic activities from existing enzymes and in facilitating the emergence of enzymatic activity de novo on scaffolds that were previously non-catalytic. There are also an increasing number of examples in the literature of targeted engineering of conformational d
The most frequently recurring cancer-associated DNA polymerase ε (Pol ε) mutation is a P286R substitution in the exonuclease domain. While originally proposed to increase genome instability by disrupting exonucleolytic proofreading, the P286R variant was later found to be significantly more pathogenic than Pol ε proofreading deficiency per se. The mechanisms underlying its stronger impact remained
In recent years, it has become increasingly clear that many enzymes are catalytically "promiscuous". This can provide a springboard for protein evolution, allowing enzymes to acquire novel functionality without compromising their native activities. We present here a detailed study of Pseudomonas aeruginosa arylsulfatase (PAS), which catalyzes the hydrolysis of a number of chemically distinct subst
Kommuner har bestämmanderätt över planprocesser och det finns idag en diskussion om huruvida det byggs för mycket på värdefull åkermark. Överexploatering av jordbruksmark kan bero på att kommuner saknar tillräckliga incitament att beakta markens värde för en tryggad nationell livsmedelsförsörjning i sina beslutsprocesser. För att införliva detta värde i beslutsprocessen kan dagens skydd i miljöbal
The streaming instability is a mechanism whereby pebble-sized particles in protoplanetary discs spontaneously come together in dense filaments, which collapse gravitationally to form planetesimals upon reaching the Roche density. The extent of the filaments along the orbital direction is nevertheless poorly characterised, due to a focus in the literature on small simulation domains where the behav
We uncover the occurrence of shear banding in dense suspensions of compressible microgels. Velocimetry measurements evidence the presence of permanent but unsteady shear-banding for sufficiently small Peclet numbers, with the formation of a central plug-like flow. Small-angle neutron scattering experiments under shear link the observed banding phenomenon to structural variations along the velocity
Which linguistic labels we use to name ourselves and others – such as disabled and non-disabled – make a difference regarding how we see ourselves and each other. Such labels may also say something about how we view society and the roles of people in it, as illustrated by the choice between people-first and identity-first labels. In the present study, we use a sample of 56,666 articles published b
Objectives: It has been belived that changes in diastolic blood velocities in the fetal ductus venosus were due to increased central venous pressure secondary to increased fetal heart strain during hypoxia or heart failure. There have been recent reports of changes in ductus venosus blood velocity without signs of increased fetal heart strain. The aim of this evaluation was to compare blood veloci
Liquid-liquid phase separation (LLPS) constitutes a crucial phenomenon in biological self-organization, not only intervening in the formation of membraneless organelles but also triggering pathological protein aggregation, which is a hallmark in neurodegenerative diseases. Employing incoherent quasi-elastic neutron spectroscopy (QENS), we examine the short-time self-diffusion of a model protein un
Peritoneal dialysis (PD) is a cost-effective, home-based kidney replacement therapy that enhances patient autonomy. Nevertheless, the clinical use of PD is limited by chronic fluid overload and excessive glucose absorption, which can lead to complications, such as cardiovascular disease, metabolic disturbances, and deterioration of the peritoneal membrane.The aims of this thesis were to examine gl
We investigate alternative strategies against reference bias and postmortem damage in low coverage paleogenomes. Compared to alignment to the linear reference genome, we show that masking known polymorphic sites and graph alignment effectively remove reference bias, but only starting from raw read files. We next study approaches to overcome postmortem damage: trimming, rescaling, and our newly dev
Colour polymorphism is a widespread phenomenon in natural populations of several species. In particular, it is especially common on marine gastropod species from the genus Littorina. Recently, it has been argued that intrapopulation shell colour polymorphism in Littorina fabalis could be caused by negative frequency-dependent sexual selection via a mechanism of mate choice (indirectly estimated th
Understanding predictors of climate policy support is important for tackling climate change. Previous research demonstrated that policy support is partially driven by cultural worldviews. Yet, treating policies as a homogeneous concept, this literature neglected the existence of different policy types. Making this distinction is important because each type implies a distinct solution to the same p
In addition to biological factors, maternal exposures during pregnancy can contribute to leukemogenesis in offspring. We conducted a population-based cohort study in Sweden to investigate the association between risk of acute lymphoblastic leukemia (ALL) in offspring and maternal anthropometrics during pregnancy. A total of 2,961,435 live-born singletons during 1983-2018 were followed from birth t
Many local governments have embraced sustainability as an overarching performance goal, and they increasingly generate performance information to track, govern and communicate their progress in sustainable development. Local governments face multiple overlapping and sometimes conflicting institutional logics, but very little research has examined how these logics influence performance management.
Background: Neural crest cells (NCCs) are migratory embryonic stem cells that give rise to a diverse set of cell types. Here we describe the dynamic distribution of NCCs in developing embryos of the common wall lizard Podarcis muralis inferred from 10 markers. Our aim is to provide insights into the NCC development of lacertid lizards and to infer evolutionary modifications by comparisons to other
Over the last decades, scholars have increasingly called for the ‘deterritorialization’ of the notion of citizenship. The realities concerning citizenship have changed with new expressions of transnationalism. However, whereas the main body of research has focused on the transnational aspects of citizenship among migrants in the form of their transnational political practices and dual nationalitie
In stainless steel turning, cutting tool life is often limited by excessive localised damage at the depth of cut line, known as notch wear. Previous research revealed that notch wear in CVD (chemical vapour deposition) Al2O3/Ti(C,N) coated WC-Co tools begins as a coating brittle fracture already after 0.3 m of cutting. This paper investigates the impact of cutting tools and workpiece materials on
