Life Satisfaction in Persons with Late Effects of Polio

To assess satisfaction with life as a whole and with ten domains of life satisfaction in Swedish persons with late effects of polio, to describe the relationship with sex, age, marital status, use of mobility aids and self-perceived needs of instrumental support, and to compare the level of life satisfaction with a Swedish reference sample. A cross-sectional study of 160 persons with verified late

Cattle, Diamonds and Institutions: Main drivers of Botswana's economic development, 1850 to present

This study investigates the role of political as well as economic institutions, factor endowments and geography as main drivers of change in Botswana’s long-term economic development, from 1850 to the present. The claim that we need to embrace multi-causal explanations giving equal explanatory value to all mentioned potential drivers is made. Further, in order not to compress history, we should gi

Diabetes Mellitus and Elevated Copeptin Levels in Middle Age Predict Low Cognitive Speed after Long-Term Follow-Up.

Background/Aims: We examined the potential impact of vascular risk factors including copeptin - a robust surrogate marker of arginine vasopressin associated with the metabolic syndrome and diabetes risk - on future cognitive abilities in a population-based cohort. Methods: Participants (n = 933) were investigated using baseline data, including copeptin levels, and data collected 16 years later usi

Millennial scale cyclicity in the geodynamo inferred from a dipole tilt reconstruction

Constraining past changes in the strength and configuration of the geomagnetic field provides a valuable perspective on the processes that govern the geodynamo. Here we update a modelled dipole tilt reconstruction for the last 9000 years by using palaeomagnetic records that originate from globally well-distributed sites. Some features predicted by earlier dipole models become more distinct due to

Contribution of diet to the composition of the human gut microbiota.

In the human gut, millions of bacteria contribute to the microbiota, whose composition is specific for every individual. Although we are just at the very beginning of understanding the microbiota concept, we already know that the composition of the microbiota has a profound impact on human health. A key factor in determining gut microbiota composition is diet. Preliminary evidence suggests that di

Basic principles of scanning space astrometry

We outline the basic principles of scanning space astrometry, such as represented by Hipparcos, Gaia, and some other astrometric satellites planned or proposed. We explain the need for large-angle measurements, why these are essentially one-dimensional, how it is possible to determine absolute parallaxes, and why a Hipparcos-type scanning law is favourable. We discuss the choice of the basic angle

In Silico Cardiac Risk Assessment in Patients With Long QT Syndrome Type 1: Clinical Predictability of Cardiac Models

Objectives The study was designed to assess the ability of computer-simulated electrocardiography parameters to predict clinical outcomes and to risk-stratify patients with long QT syndrome type 1 (LQT1). Background Although attempts have been made to correlate mutation-specific ion channel dysfunction with patient phenotype in long QT syndrome, these have been largely unsuccessful. Systems-level

Pharmacological stimulation of sigma-1 receptors has neurorestorative effects in experimental parkinsonism.

The sigma-1 receptor, an endoplasmic reticulum-associated molecular chaperone, is attracting great interest as a potential target for neuroprotective treatments. We provide the first evidence that pharmacological modulation of this protein produces functional neurorestoration in experimental parkinsonism. Mice with intrastriatal 6-hydroxydopamine lesions were treated daily with the selective sigma

Defect evaluation in InGaAs field effect transistors with HfO2 or Al2O3 dielectric

The performance of InGaAs metal oxide semiconductor field effect transistors with Al2O3 or HfO2 as gate oxide is evaluated and compared. The Al2O3 transistors show the lowest subthreshold slope and mid gap D-it, however, the HfO2 transistors reach a higher maximum transconductance (g(max)) due to the higher oxide capacitance. Both high-kappa dielectrics show a g(m)-frequency dispersion due to tunn

Month-to-month variation in sleep among healthy, Scandinavian daytime workers

Background. The overall purpose of the present study was to attain more insight in month-to-month variation of sleep duration and quality in order to improve design and interpretation of, e.g. epidemiological studies using sleep as outcome. Methods. The study design entailed monthly self-reports from 38 (26 women/12 men) daytime workers, who completed the Karolinska Sleep Diary (KSD) once a month

Can we trust Web-page metadata?

A statistical study of embedded metadata in a sample of more than 4 million HTML Web-pages is reported. The paper tries to determine and quantify the validity of this metadata. Of particular interest is to see if it is trustworthy enough for determining the topic of a Web-page. Datasets are collected by a Web crawler running both as a general and a focused crawler. Metadata fields 'title', 'author

What Reaches the Antenna? How to Calibrate Odor Flux and Ligand-Receptor Affinities

Physiological studies on olfaction frequently ignore the airborne quantities of stimuli reaching the sensory organ. We used a gas chromatography-calibrated photoionization detector to estimate quantities released from standard Pasteur pipette stimulus cartridges during repeated puffing of 27 compounds and verified how lack of quantification could obscure olfactory sensory neuron (OSN) affinities.

Modelling of mineral dust for interglacial and glacial climate conditions with a focus on Antarctica

The mineral dust cycle responds to climate variations and plays an important role in the climate system by affecting the radiative balance of the atmosphere and modifying biogeochemistry. Polar ice cores provide unique information about deposition of aeolian dust particles transported over long distances. These cores are a palaeoclimate proxy archive of climate variability thousands of years ago.

Spatial Forecast Verification: Image Warping

In response to a growing need for more informative forecast verification in the face of gridded verification sets, many new methods have been proposed. While widely varying in their approaches, the new methods generally fall into two ma- jor categories of filter and displacement, each of which can be further subdivided. One of the displacement approaches, a field deformation approach known as imag

Cocaine- and Amphetamine-regulated Transcript (CART) Protects Beta Cells against Glucotoxicity and Increases Cell Proliferation

Cocaine and amphetamine-regulated transcript (CART) is an islet peptide that promotes glucose stimulated insulin secretion in beta cells via cAMP/PKA-dependent pathways. In addition, CART is a regulator of neuronal survival. In this study, we examined the effect of exogenous CART 55-102 on beta cell viability and dissected its signaling mechanisms. Evaluation of DNA fragmentation and chromatin con

Structural and optical characterization of Mg-doped GaAs nanowires grown on GaAs and Si substrates

We report an investigation on the morphological, structural, and optical properties of large size wurtzite GaAs nanowires, low doped with Mg, grown on GaAs(111) B and Si(111) substrates. A higher density of vertical nanowires was observed when grown upon GaAs(111) B. Very thin zinc-blende segments are observed along the axis of the nanowires with a slightly higher linear density being found on the
