Differences in physical activity patterns in patients with spondyloarthritis.

OBJECTIVE: To study patient reported physical activity in patients with spondyloarthritis (SpA) and possible differences in physical activity patterns between the SpA subtypes and genders. METHODS: In 2009 a questionnaire including questions concerning physical activity was sent to patients with a SpA diagnosis (n=3711). The WHO "Global recommendations of physical activity for health" requirin

Prognostic implications of mutation-specific QTc standard deviation in congenital long QT syndrome

BACKGROUND Individual corrected QT interval (QTc) may vary widely among carriers of the same long QT syndrome (LOTS) mutation. Currently, neither the mechanism nor the implications of this variable penetrance are well understood. OBJECTIVES To hypothesize that the assessment of QTc variance in patients with congenital LOTS who carry the same mutation provides incremental prognostic information on

Accuracy and reproducibility of a novel dynamic volume flow measurement method.

In clinical practice, blood volume flow (BVF) is typically calculated assuming a perfect parabolic and axisymmetric velocity distribution. This simple approach cannot account for the complex flow configurations that are produced by vessel curvatures, pulsatility and diameter changes and, therefore, results in a poor estimation. Application of the Womersley model allows compensation for the flow di

The new work ethics of consumption and the paradox of mundane brand resistance

In terms of consumer resistance and marketplace ideologies, consumer researchers have called for a more nuanced conceptualization of consumption moralism in order to avoid the simplistic trope of inside/outside the marketplace (e.g. Arnould, 2007; Luedicke et al., 2010; Penaloza and Price, 1993; Thompson, 2004). With the aim of contributing to this quest, this article brings together two originall

Risk of hepatocellular carcinoma and cancers at other sites among patients diagnosed with chronic hepatitis B virus infection in Sweden.

Hepatitis B virus (HBV) infection is one of most common viral infections worldwide. While chronic HBV infection has been shown consistently to be associated with hepatocellular carcinoma, data on associations with cancers at other sites are limited. In this study a total of 10,197 patients were diagnosed with chronic HBV infection in Sweden, and they were retrieved from the nationwide Swedish Hosp

Product variety and the demographic transition

Why does the rate of population growth decline in the face of economic growth? We show that growing product variety may induce a permanent reduction in the demand for children and a continuous rise in income and consumption. (C) 2009 Elsevier B.V. All rights reserved.

One man, 73 years, and 25 species. Evaluating phenological responses using a lifelong study of first flowering dates.

Phenological shifts linked to global warming reflect the ability of organisms to track changing climatic conditions. However, different organisms track global warming differently and there is an increasing interest in the link between phenological traits and plant abundance and distribution. Long-term data sets are often used to estimate phenological traits to climate change, but so far little has

Low variability and absence of phenotypic correlates of Clock gene variation in a great tit Parus major population

Studies of a range of taxa, including birds, have revealed latitudinal clines in allele length at the conserved Clock locus, a gene with known influences on behaviour and physiology. Such clines might reflect adaptation to seasonal variation, a suggestion supported by a recent within-population analysis of blue tits Cyanistes caeruleus, which found associations between Clock genotype and timing of

Scaling up requirements engineering - exploring the challenges of increasing size and complexity in market-driven software development

[Context & motivation] Growing software companies with increasing product complexity face the issue of how to scale up their Requirements Engineering (RE) practices. In market-driven requirements engineering, release planning and scoping decisions are increasingly challenging as the size and complexity increases. [Problem] This paper presents initial results of an on-going exploratory, qualita

Topological crystalline insulator states in Pb1-xSnxSe

Topological insulators are a class of quantum materials in which time-reversal symmetry, relativistic effects and an inverted band structure result in the occurrence of electronic metallic states on the surfaces of insulating bulk crystals. These helical states exhibit a Dirac-like energy dispersion across the bulk bandgap, and they are topologically protected. Recent theoretical results have sugg

Are children with stronger cognitive capacity more or less disturbed by classroom noise and dysphonic teachers?

Purpose: This study aimed to explore if dysphonic voice quality affects children's performance on a language comprehension test, the Test for Reception of Grammar-2 (TROG-2), performed in simultaneous background noise (non-semantic babble). A further aim was to investigate the role of Working Memory Capacity (WMC) and Executive Functioning (EF) in coping with the voice against a background of babb

Functional consequences of sequence variation in the pheromone biosynthetic gene pgFAR for Ostrinia moths

Pheromones are central to the mating systems of a wide range of organisms, and reproductive isolation between closely related species is often achieved by subtle differences in pheromone composition. In insects and moths in particular, the use of structurally similar components in different blend ratios is usually sufficient to impede gene flow between taxa. To date, the genetic changes associated

Surface Adsorption and Phase Separation of Oppositely Charged Polyion-Surfactant Ion Complexes: 3. Effects of Polyion Hydrophobicity.

The adsorption to hydrophilic silica surfaces in relation to the bulk phase behavior was investigated by in situ null ellipsometry and bulk turbidity measurements for four cationic copolymers of varying hydrophobicity in mixtures with anionic surfactant sodium dodecylsulfate (SDS). The purpose was to reveal the effect of polyion hydrophobicity on the association with surfactant at surfaces and in

Low rate of fistula formation after Sommerlad palatoplasty with or without lateral incisions: An analysis of risk factors for formation of fistulas after palatoplasty.

The aim of palate repair is to restore normal eating and drinking function and normal speech development and still maintain undisturbed facial growth. The repair should be performed with a low frequency of complications. A number of factors are thought to contribute to the formation of fistulas after palatoplasty; they include patient factors and treatment issues. The aim of this study was to revi

Clients’ experiences of housing adaptations: a longitudinal mixed-methods study.

Purpose: To explore clients' experience of the housing adaptations (HAs) over time in relation to housing and health. Method: A multiple longitudinal case study, employing an embedded mixed-method design was used. Four participants were included and data from semi-structured interviews were combined with data from structured survey assessments. Results: HA made it possible to maintain valuable

An oat branmeal influences blood insulin levels and related gene sets in peripheral blood mononuclear cells of healthy subjects

The understanding of how fibre-rich meals regulate molecular events at a gene level is limited. This pilot study aimed to investigate changes in gene expression in peripheral blood mononuclear cells (PBMCs) from healthy subjects after consumption of an oat bran-rich meal. Fifteen subjects (8 men and 7 women, aged 20-28 years) ingested meals with oat bran or a control meal after an overnight fast.

Archaeal abundance across a pH gradient in an arable soil and its relationship with bacterial and fungal growth rates.

Soil pH is one of the most influential factors for the composition of bacterial and fungal communities, but the influence of soil pH on the distribution and composition of soil archaeal communities has yet to be systematically addressed. The primary aim of this study was to determine how total archaeal abundance (qPCR based estimates of 16S rRNA gene copy numbers) is related to soil pH across a pH

Credit-implied forward volatility and volatility expectations

We show how one can back out implied forward volatility term structures from credit default swap spreads. Such forward stock volatility term structures are useful for instance in forward start option pricing. We find the term structure to be downward-sloping, and the credit market's volatility forecasts tend to vary more across time than across maturities. Long-term volatility expectations, in tur
