Streptococci are common causes of infective endocarditis (IE) and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has provided a practical tool for their species determination. We aimed to investigate if particular groups of non-beta heamolytic streptococci were associated with IE or to specific presentations thereof. The Swedish Registry of Infective En

In this work, we report a method that allows the deterministic, photo-controlled covalent assembly of nanoparticles directly on surface. As a model system, we study the conjugation of molecularly imprinted polymer (MIP) nanoparticles on a glass surface and confirm that the immobilized nanoparticles maintain their molecular recognition functionality. The glass slide was first modified with perfluor

Classification of urinary tract infections (UTI) is important for clinical decisions, research, quality measurement and teaching. Current definitions of UTI are above all based on the concept of the two main categories, complicated and uncomplicated UTI. The category "complicated UTI" especially is very heterogeneous and not always clear. We propose the EAU/ESIU classification system ORENUC based

Specific combinations of dietary fiber (DF) have been observed to result in improved glucose tolerance at a subsequent standardized breakfast. Arabinoxylan oligosaccharides (AXOS) are considered as DF with prebiotic potential, but so far no studies have investigated their metabolic effects in humans. This randomized cross-over study evaluated the overnight impact of breads containing AXOS-rich whe

Chemotherapy is used in the treatment of children and adolescents with malignant diseases. Some of the chemotherapeutic agents are highly toxic and may cause a number of side effects. The primary objective of this study was to evaluate the long-term effects on hearing in cancer survivors who had received platinum-based chemotherapy in childhood or adolescence.

Bentonite is to be used as a sealing material for long-term storage of radioactive waste. During permafrost periods the buffer may freeze, causing the following: montmorillonite dehydration, ice formation, and pressure build-up that may fracture the surrounding rock. No previous study has been done on freezing of bentonite in saline water. Using small and wide angle X-ray scattering, the present s

Although well characterized in animals, brain damage in humans treated with hypothermia after cardiac arrest has not been systematically explored. In this study we aimed to describe the characteristic trait of selective eosinophilic neuronal death (SEND), and its correlation with time to return of spontaneous circulation (ROSC) in cardiac arrest patients who died after hypothermia treatment and we

Computing is no longer considered a subject area only relevant for a narrow group of professionals, but rather as a vital part of general education that should be available to all children and youth. Since making changes to national curricula takes time, people are trying to find other ways of introducing children and youth to computing. In Sweden, several current initiatives by researchers and te

This article pursues the idea that null arguments are derived without any statement or parameter, instead following "naturally" from 3rd factor principles and effects (in the sense of Chomsky 2005). The article thus contributes to the program of eliminating statements in grammar in favor of general factors. More specifically, it develops a theory of C/edge linking in terms of syntactically active

In this work we extend two dual color decompositions of Yang-Mills amplitude to one-loop level. Starting from double-copy expression we translate the Yang-Mills integrand into the dual Del Duca-Dixon-Maltoni formulation and subsequently to the dual color-ordered formula. The dual trace factors are obtained after simultaneously solving the one-loop Kleiss-Kuijf relations, the reflection relation, a

In this paper, a performance benchmark for the assessment of two feedforward control architectures for the load disturbance compensation problem is proposed. In particular, two indices are devised so that the advantage of using a feedforward compensator with respect to the use of a feedback controller only is quantified. Furthermore, these metrics will help to make quantitative comparisons among d

Evaluation of structure and morphology of extruded wheat gluten (WG) films showedWGprotein assemblies elucidated on a range of length scales from nano (4.4 Å and 9 to 10 Å, up to 70 Å) to micro (10 μm). The presence of NaOH in WG films induced a tetragonal structure with unit cell parameters, a = 51.85 Å and c = 40.65 Å, whereasNH4OHresulted in a bidimensional hexagonal close-packed (HCP) structur

Tissue factor pathway inhibitor (TFPI) inhibits tissue factor-induced coagulation, but may, via its C-terminus, also modulate cell surface-, heparin-, lipopolysaccharide interactions as well as participate in growth inhibition. Here we show that C-terminal TFPI peptide sequences are antimicrobial against the Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, Gram-positive Bacillus

Few studies have investigated loneliness in relation to health care consumption among frail older people. The aim of this study was to examine loneliness, health-related quality of life (HRQoL), and health complaints in relation to health care consumption of in- and outpatient care among frail older people living at home. The study, with a cross-sectional design, comprised a sample of 153 responde

We have investigated the photofragmentation properties of the three-membered ring heterocyclic molecule ethylene sulfide or thiirane, C2H4S, by time-of-flight mass spectroscopy. Positive ions have been collected as a function of photon energy around the S K ionization threshold. Branching ratios were derived for all detected ions, which are informative of the decay dynamics and photofragmentation

The dilute (Ga,Mn)As became a model ferromagnetic semiconductor, however there is still a disagreement on the source of its magnetism. In this paper, we verify the ellipsometric results and compare them with more precise photoreflectance method, which gives an important insight into the interaction of the Mn-related states with the ones of GaAs valence band. No spectral shifts observed for the E-1

COPD is a progressive disease, which can take different routes, leading to great heterogeneity. The aim of the post-hoc analysis reported here was to perform continuous analyses of advanced lung function measurements, using linear and nonlinear regressions.

Blood pressure (BP) is a heritable risk factor for cardiovascular disease. To investigate genetic associations with systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP), and pulse pressure (PP), we genotyped ∼50,000 SNPs in up to 87,736 individuals of European ancestry and combined these in a meta-analysis. We replicated findings in an independent set of 68,368 individuals of Europe
