There is an overlap regarding Pittsburgh compound B (PIB) retention in patients clinically diagnosed as Alzheimer's disease (AD) and non-AD dementia. The aim of the present study was to investigate whether there are any differences between PIB-positive and PIB-negative patients in a mixed cohort of patients with neurodegenerative dementia of mild severity regarding neuropsychological test performa

We consider the problem of sparse modeling of a signal consisting of an unknown number of exponentially decaying sinusoids. Since such signals are not sparse in an oversampled Fourier matrix, earlier approaches typically exploit large dictionary matrices that include not only a finely spaced frequency grid but also a grid over the considered damping factors. The resulting dictionary is often very

När källsorterat matavfall från hushållen rötas i en biogasanläggning av modellen omrörd tank behövs en förbehandling för att göra materialet pumpbart och ta bort orenheter. En typ av förbehandling innebär att avfallet passerar genom en skruvpress som delar avfallet i en pumpbar fraktion och en torr fraktion, så kallat rejekt. På NSR förbehandlas matavfallet med denna teknik och rejektet skickas i

An overview of the integration of the Skåne provinces in the Swedish state after 1658.

Researchers examining self-esteem functioning typically consider self-esteem either an affective or competence related trait. However, to capture more precisely the role of self-esteem in behavior we need to view self-esteem both as something people hold and as something they strive for, and determine the relation between these aspects. In the present study the consequences of the dynamic interpla

Background: Caloramator celer is a strict anaerobic, alkalitolerant, thermophilic bacterium capable of converting glucose to hydrogen (H2), carbon dioxide, acetate, ethanol and formate by a mixed acid fermentation. Depending on the growth conditions C. celer can produce H2 at high yields. For a biotechnological exploitation of this bacterium for H2 production it is crucial to understand the factor

Popular Abstract in Swedish Systemiska biomarkörer hos patienter med aortaaneurysm. Kroppspulsådern eller aorta är huvudstammen som för syrerikt blod från hjärtat till perifera delar av kroppen. Kroppspulsåderbråck (aneurysm) i buken kännetecknas av försvagning i kärlväggen som i sin tur leder till vidgning av kroppspulsådern. Aneurysm är fyra gånger vanligare hos män än hos kvinnor över 65 års ålAbdominal aortic aneurysm (AAA) develops in 3-6% of the population over 65 years and affects mainly men. AAA has a complex etiology involving inflammation, proteolysis, fibrinolysis and coagulation. The general aim of the present thesis was to study the associations between markers of inflammation, proteolysis, fibrinolysis and coagulation with aneurysm size and growth. In paper I associations bet

Background: Prior reports suggest a link between gonadotropin-releasing hormone (GnRH) and gastrointestinal function. The aim of the study was to prospectively investigate women subjected to in vitro fertilization (IVF) using the GnRH analog buserelin, taking into account gastrointestinal symptoms and antibody development against buserelin, GnRH, luteinizing hormone (LH), and their receptors. Meth

This paper focuses on two phenomena, a semanticization of the gender system that started in West Jutland, the southwestern part of Denmark, and so-called “pancake sentences” in Mainland Scandinavian (primarily Danish and Swedish). In West Jutlandic, substance-denoting nouns (as well as event nouns) are obligatorily constructed with a prenominal neuter element, primarily det, for example det mælk

The poorly known B(E2; 0(+) -> 2(+)) values of Sn-112 and Sn-114 have been measured to high precision. Two Coulomb excitation experiments were performed to determine the reduced transition probabilities relative to Sn-116 in order to minimize the systematic errors. The obtained B(E2 up arrow) values of 0.242(8) e(2)b(2) for Sn-112 and 0.232(8) e(2)b(2) for Sn-114 confirm the tendency of large B(E2

A multi-center study has been set up to accurately characterize the optical properties of diffusive liquid phantoms based on Intralipid and India ink at near-infrared (NIR) wavelengths. Nine research laboratories from six countries adopting different measurement techniques, instrumental set-ups, and data analysis methods determined at their best the optical properties and relative uncertainties of

This Letter presents a measurement of W(+/-)Z production in 1.02 fb(-1) of pp collision data at root s = 7 TeV collected by the ATLAS experiment in 2011. Doubly leptonic decay events are selected with electrons, muons and missing transverse momentum in the final state. In total 71 candidates are observed, with a background expectation of 12.1 +/- 1.4(stat.)(-2.0)(+4.1)(syst.) events. The total cro

A search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV is reported, based on a total integrated luminosity of up to 40 pb(-1) collected by the ATLAS detector in 2010. Several Higgs boson decay channels: H -> gamma gamma, H -> ZZ(()*()) -> llll, H -> ZZ -> LL nu nu, H -> ZZ -> llqq, H -> WW(*()) -> l nu l nu and H -> WW -> l nu qq

As the chemical environment of semen diluents can have a profound effect on sperm quality, we examined the effect of temperature and pH on the motility and viability of sperm in the ostrich. Semen was collected from four males, each male being replicated three times. Ejaculates were diluted and incubated for 10 min at 20 degrees C and 40 degrees C in four different buffers, temperature adjusted at

A Primary Reference Preparation has been produced using pure, recombinant, Cystatin C in a solvent of 0.1 mol/L KCl. Dry mass determination of the Primary Reference Preparation resulted in a Cystatin C concentration of 5.20 g/L. Agarose-electrophoresis and SDS-electrophoresis, as well as N-terminal sequencing, verified the purity, homogeneity and identity of Cystatin C in the Primary Reference Pre

We investigated whether infections with Parvovirus B19 and Herpes viruses in early pregnancy increase risks of second trimester miscarriage or delivery before 32 gestational weeks. Blood samples taken in early pregnancy were analyzed for Parvovirus B19 or Herpes viruses. Viremia was found in blood samples of 11 (4.7%) women with second trimester miscarriage and 10 (3.7%)women with very preterm bir

Fischer-Tropsch (FT) synthesis is an important process to manufacture hydrocarbons and oxygenated hydrocarbons from mixtures of carbon monoxide and hydrogen (syngas). The catalysis process occurs on, for example, cobalt metal surfaces at elevated temperatures and pressures. A fundamental understanding of the reduction pathway of supported cobalt oxides, and the intermediate species present during

The vegetation component in climate models has advanced since the late 1960s from a uniform prescription of surface parameters to plant functional types (PFTs) PFTs are used in global land-surface models to provide parameter values for every model grid cell With a simple photosynthesis model we derive parameters for all site years within the Fluxnet eddy covariance data set We compare the model pa

Factor I (FI) is the major complement inhibitor that degrades activated complement components C3b and C4b in the presence of specific cofactors. Complete FI deficiency results in secondary complement deficiency due to uncontrolled spontaneous alternative pathway activation. In this study we describe two unrelated patients with complete FI deficiency and undetectable alternative complement pathway
