BACKGROUND: Different movement efficiency in overweight children may affect accelerometer output data. The purpose was to investigate the ability of accelerometers to assess physical activity intensity and number of steps in normal-weight compared with overweight children. METHODS: Eleven normal-weight and 14 overweight African American children walked at 2, 4, 5, and 6 km/h on a treadmill wearin
During locomotion, neurons in motor cortex exhibit profound step-related frequency modulation. The source of this modulation is unclear. The aim of this study was to reveal the contribution of different limb controllers (locomotor mechanisms of individual limbs) to the periodic modulation of motor cortex neurons during locomotion. Experiments were conducted in chronically instrumented cats. The ac
OBJECTIVES: Alzheimer disease (AD) can now be diagnosed in subjects with mild cognitive impairment (MCI) using biomarkers. However, little is known about the rate of decline in those subjects. In this cohort study, we aimed to assess the conversion rate to dementia and identify prognostic markers in subjects with MCI and evidence of amyloid pathology. METHODS: We pooled subjects from the VU Un
The periodontal pathogen Porphyromonas gingivalis is highly resistant to the bactericidal activity of human complement, which is present in the gingival crevicular fluid at 70% of serum concentration. All thirteen clinical and laboratory P. gingivalis strains tested were able to capture the human complement inhibitor C4b-binding protein (C4BP), which may contribute to their serum resistance. Accor
Popular Abstract in Swedish Syftet med denna avhandling är att undersöka vilken roll synlighet spelar i skapandet och utmanandet av tillhörighet till politiska gemenskaper. Baserat på en empirisk studie av ryska medier under 2010-talet föreslås ett sätt att teoretiskt begreppsliggöra förhållandet mellan synlighet och tillhörighet, som utgår från idén att vad som blir synligt för en publik och hur,The purpose of this dissertation is to explore the role of visibility in the production and contestation of belonging to political communities. On the basis of an empirical enquiry of Russian media during the 2010s, a theoretical conceptualization of the relation between visibility and belonging is suggested, starting in the idea that what becomes visible to publics and how, and what is rendered i
An important failure mode of RC beams retrofitted with FRP plates is plate end debonding. Design codes provide equations for estimating shear stress at the plate end, but none of these equations include the FRP to concrete width ratio. This paper suggests an improved equation for calculating shear stress that includes the width ratio. The new equation was obtained by fitting 3D nonlinear FEM resul
Bigeye tuna (Thunnus obesus) have distinctive depth distributions and vertical movement patterns. They remain in the uniformed temperature surface layer at night and can descend to greater than 500 m depth at dawn. They thus mirror the vertical migrations of the small nektonic organisms of the deep sound scattering layer and extensively exploit these as a food resource. At their maximum depths, bi
The objective of this paper is to describe the evaluation and effects of a major reconstruction of an arterial street in Eskilstuna, a medium sized Swedish town. The aim of the reconstruction was to minimize the barrier effects of the arterial street and by that create a stronger connection between the town center, on one side of the street, and the town-river, on the other; but also to create gen
PURPOSE: The nature of the relationship between inflammation and elevated serum lipid levels is incompletely understood. This longitudinal study explores whether elevated levels of inflammation-sensitive plasma proteins (ISPs) are a risk factor for developing increased cholesterol and triglyceride levels. METHODS: Five ISPs (fibrinogen, orosomucoid, alpha(1)-antitrypsin, haptoglobin, and cerulopla
The bis(triarylamine) systems 1-5 were synthesized and investigated by spectroscopic and electrochemical methods. They all have an aromatic five-membered ring system in common as a central part of their pi-electron bridge. The absorption spectra are presented. All compounds undergo five oxidations whereupon only the first two are reversible under semi-infinite cyclic voltammetry conditions. The sp
The human anaphylatoxin peptide C3a, generated during complement activation, exerts antimicrobial effects. Phylogenetic analysis, sequence analyses, and structural modeling studies paired with antimicrobial assays of peptides from known C3a sequences showed that, in particular in vertebrate C3a, crucial structural determinants governing antimicrobial activity have been conserved during the evoluti
Decomposition of unpolluted Scots pine needle litter was studied in two heavy-metal-pollution gradients in Sweden; one near a brass mill and the other around a primary smelter. In the latter area locally collected polluted Scots pine needle litter was also incubated. Decomposition rates were strongly influenced by the metal pollution and a decrease in the rate of mass-loss occurred. In the brass-m
Background Stent implantation is an effective method for treatment of atherosclerotic disease. Factors predisposing to in-stent restenosis are still largely unknown. Contact allergy to metal ions eluted from the stent has been suggested to be a risk factor. Objectives To explore whether there is a possible induction of contact allergy to metals used in stents among patients with a stainless steel
