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

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.

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

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

A Memory-Efficient Finite Volume Method for Advection-Diffusion-Reaction Systems with Non-Smooth Sources

We present a parallel matrix-free implicit nite volume scheme for the solution of unsteady three-dimensional advection-diusion-reaction equations with smooth and Dirac-Delta source terms. The scheme is formally second order in space and a Newton-Krylov method is employed for the appearing nonlinear systems in the implicit time integration. The matrix-vector product required is hardcoded without an

Low Levels of IgM Antibodies against an Advanced Glycation Endproduct-Modified Apolipoprotein B100 Peptide Predict Cardiovascular Events in Nondiabetic Subjects.

Increased glucose levels are associated with the generation of advanced glycation endproduct (AGE) modifications. Interaction between AGE-modified plaque components and immune cells is believed to have an important role in the development of vascular complications in diabetes. Methylglyoxal (MGO) is one type of reactive aldehyde that gives rise to AGE modification. The present study analyzed wheth

Positive correlation between tumor necrosis factor (TNF)-alpha and cardiorespiratory fitness after six-months of regular aerobic exercise in Peruvian Amerindian women

Background: Adipose tissue is a source of inflammatory cytokines which may influence insulin action. Aim: To evaluate exercise effects on plasma (p)-levels of tumor necrosis factor (TNF)-alpha, and interleukin (IL)-6 in Peruvian Amerindian women. Material and Methods: After five years of observation during which p-glucose deteriorated and weight increased, 44 Peruvian Amerindian women aged 20-59 y

Calibration and validation of a phenomenological influent pollutant disturbance scenario generator using full-scale data.

The objective of this paper is to demonstrate the full-scale feasibility of the phenomenological dynamic influent pollutant disturbance scenario generator (DIPDSG) that was originally used to create the influent data of the International Water Association (IWA) Benchmark Simulation Model No. 2 (BSM2). In this study, the influent characteristics of two large Scandinavian treatment facilities are st

Catalytic Oxidation of Alkanes and Alkenes by H2O2 with a mu-Oxido Diiron(III) Complex as Catalyst/Catalyst Precursor

A new mu-oxo diiron(III) complex of the lithium salt of the pyridine-based unsymmetrical ligand 3-[(3-{[bis(pyridin-2-ylmethyl)amino]methyl}-2-hydroxy-5-methylbenzyl)(pyridin2-ylmethyl)amino] propanoate (LiDPCPMPP), [Fe-2(mu-O)(LiDPCPMPP)(2)](ClO4)(2), has been synthesized and characterized. The ability of the complex to catalyze oxidation of several alkanes and alkenes has been investigated by us

Genetic Variation in KLK2 and KLK3 Is Associated with Concentrations of hK2 and PSA in Serum and Seminal Plasma in Young Men

BACKGROUND: Genetic variants in KLK2 and KLK3 have been associated with increased serum concentrations of their encoded proteins, human kallikrein-related peptidase 2 (hK2) and prostate-specific antigen (PSA), and with prostate cancer in older men. Low PSA concentrations in seminal plasma (SP) have been associated with low sperm motility. To evaluate whether KLK2 and KLK3 genetic variants affect p

Identification and Functional Characterization of G6PC2 Coding Variants Influencing Glycemic Traits Define an Effector Transcript at the G6PC2-ABCB11 Locus.

Genome wide association studies (GWAS) for fasting glucose (FG) and insulin (FI) have identified common variant signals which explain 4.8% and 1.2% of trait variance, respectively. It is hypothesized that low-frequency and rare variants could contribute substantially to unexplained genetic variance. To test this, we analyzed exome-array data from up to 33,231 non-diabetic individuals of European a

Indigenous children living nearby plantations with chlorpyrifos-treated bags have elevated 3,5,6-trichloro-2-pyridinol (TCPy) urinary concentrations

Background: The US Environmental Protection Agency voluntary phased-out residential use of chlorpyrifos in 2001. In contrast, in Costa Rica, chlorpyrifos-treated bags are increasingly used to protect banana and plantain fruits from insects and to fulfill product standards, even in populated areas. Objectives: To evaluate children's exposure to chlorpyrifos in villages situated nearby banana planta

REVIEW OF PARTICLE PHYSICS Particle Data Group

The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,283 new measurements from 899 Japers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as heavy neutrinos, supersymmetric and technicolor particl

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
