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

Differences in the profile of protection afforded by TRO40303 and mild hypothermia in models of cardiac ischemia/reperfusion injury.

The mode of protection against cardiac reperfusion injury by mild hypothermia and TRO40303 was investigated in various experimental models and compared to MitoQ in vitro. In isolated cardiomyocytes subjected to hypoxia/reoxygenation, TRO40303, MitoQ and mild hypothermia delayed mPTP opening, inhibited generation of mitochondrial superoxide anions at reoxygenation and improved cell survival. Mild h

Germline mutation in BRCA1 or BRCA2 and ten-year survival for women diagnosed with epithelial ovarian cancer

PURPOSE: To analyze the effect of germline mutations in BRCA1 and BRCA2 on mortality in patients with ovarian cancer up to 10 years after diagnosis.EXPERIMENTAL DESIGN: We used unpublished survival time data for 2,242 patients from two case-control studies and extended survival time data for 4,314 patients from previously reported studies. All participants had been screened for deleterious germlin

Biofuels: From a win-win solution to a wicked problem?

Current and recent struggles encountered in the development of the transport biofuels sector indicate a significant change in the perception of biofuels. Instead of a win-win solution, transport biofuels have become a major planning challenge. In fact, biofuels can be labelled a wicked problem. The planning studies literature offers some tools to interpret this change and guide future actions. Fir

Heparin does not seem to improve the function of pulmonary grafts for lung transplantation.

Abstract Background. It has been debated whether or not heparin infusion before or after non-heart-beating donors are declared dead improves the quality of pulmonary grafts. In clinical lung transplantation with heart-beating donors (HBDs) heparin is routinely infused prior to organ harvesting since it is believed to improve pulmonary grafts by minimizing thrombosis formation in the pulmonary graf

The relationship between longitudinal, lateral, and septal contribution to stroke volume in patients with pulmonary regurgitation and healthy volunteers

Septal systolic motion is towards the left ventricle (LV) in healthy hearts. Patients with pulmonary regurgitation (PR) and right ventricular (RV) volume overload have systolic septal motion toward the RV. This may affect the longitudinal contribution from atrioventricular plane displacement (AVPD) and septal and lateral contribution to stroke volume (SV). The study aimed to quantify these contrib

Doubly resonant three-photon double ionization of Ar atoms induced by an EUV free-electron laser

A mechanism for three-photon double ionization of atoms by extreme-ultraviolet free-electron laser pulses is revealed, where in a sequential process the second ionization step, proceeding via resonant two-photon ionization of ions, is strongly enhanced by the excitation of ionic autoionizing states. In contrast to the conventional model, the mechanism explains the observed relative intensities of

The association between meniscal damage of the posterior horns and localized posterior synovitis detected on T1-weighted contrast-enhanced MRI-The MOST study

Objective: Synovitis is thought to be a secondary phenomenon in the osteoarthritis (OA) process and the menisci might be triggers of localized synovitis. The aim was to assess the cross-sectional associations of posterior horn meniscal damage with perimeniscal synovitis, and with synovitis posterior to the posterior cruciate ligament (PCL) using contrast enhanced (CE) MRI. Design: The Multicenter

Ferrimagnetism and spin excitation in a Ni-Mn partially inverted spinel prepared using a modified polymeric precursor method

We demonstrate that a Ni-Mn oxide partially inverted spinel (Ni1-pMnv)[NivMn2-v]O-4 having inversion degree v approximate to 0.8 and produced by a modified polymeric precursor method exhibits behaviour previously reported only in monophased samples. The structure of the specimen was determined using Rietveld analysis of X-ray and neutron powder diffraction data, showing that at room temperature th

Environmental mercury exposure, semen quality and reproductive hormones in Greenlandic Inuit and European men: a cross-sectional study

Several animal studies indicate that mercury is a male reproductive toxicant, but human studies are few and contradictory. We examined semen characteristics and serum levels of reproductive hormones in relation to environmental exposure to mercury. Blood and semen samples were collected from 529 male partners of pregnant women living in Greenland, Poland and Ukraine between May 2002 and February 2

Adiponutrin: A multimeric plasma protein.

The interest in adiponutrin stems from adiponutrin variant I148M, which is strongly associated to non-alcoholic fatty liver disease. Adiponutrin has to date been considered to be solely an intracellular protein, with a role in lipid metabolism in liver and adipose tissue. However, a physiologically relevant role for adiponutrin has not been found. The aim of this study was to investigate the prese

Interdependency between average novelty, individual average novelty, and variety

Idea generation is an important part of the engineering design process, and therefore significant research efforts have focused on developing methods to support designers in generating ideas. A key factor is the measurement of ideation effectiveness. The effectiveness of idea generation methods can be measured using metrics such as novelty, variety, quantity, and quality. Average novelty (AN) of a

Potential impact of (CET) carbon emissions trading on China’s power sector: A perspective from different allowance allocation options

Abstract in UndeterminedIn Copenhagen climate conference China government promised that China would cut down carbon intensity 40–45% from 2005 by 2020. CET (carbon emissions trading) is an effective tool to reduce emissions. But because CET is not fully implemented in China up to now, how to design it and its potential impact are unknown to us. This paper studies the potential impact of introducti

Frequency stabilization to 6 x 10(-16) via spectral-hole burning

We demonstrate two-stage laser stabilization based on a combination of Fabry-Perot and spectral-hole burning techniques. The laser is first pre-stabilized by the Fabry-Perot cavity to a fractional-frequency stability of sigma(y)(tau) < 1 x 10(-13). A pattern of multiple spectral holes written in the absorption spectrum of Eu3+:Y2SiO5 serves to further stabilize the laser to sigma(y)(tau)

Cigar and pipe smoking and cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC)

The carcinogenicity of cigar and pipe smoking is established but the effect of detailed smoking characteristics is less well defined. We examined the effects on cancer incidence of exclusive cigar and pipe smoking, and in combination with cigarettes, among 102,395 men from Denmark, Germany, Spain, Sweden and the United Kingdom in the EPIC cohort. Hazard ratios (HR) and their 95% confidence interva

A CFAR Adaptive Subspace Detector Based on a Single Observation in System-Dependent Clutter Background

In this paper, the problem of detecting target in system-dependent clutter (SDC) background with a single observation from the test cell is researched. Classical detectors, such as the generalized likelihood ratio detectors (GLRDs) and the adaptive matched filters (AMFs), etc., usually deal with the clutter and the noise as a whole. The low rank detectors (LRDs) make use of the low rank property o
