Results Non-pacing associated (no pacing, no S-L-S) and pacing associated (ventricular pacing without S-L-S) onset accounted for 44.0% and 29.8% of all VT/VF, respectively. Pacing permitted (S-L-S sequences without ventricular pacing) episodes accounted for 6.4% (DDD/R), 20.0% (MVP), and 25.6% (VVI/R) of 1,356 VT/VF episodes. Pacing facilitated onset (S-L-S sequences actively facilitated by ven...

BACKGROUND Mitral valve prolapse (MVP) is a common disorder associated with mitral regurgitation, endocarditis, heart failure, and sudden death. To date, 2 MVP loci have been described, but the defective genes have yet to be discovered. In the present study, we analyzed a large family segregating MVP, and identified a new locus, MMVP3. This study and others have enabled us to explore mitral val...

Motion estimation is currently the most computationally intensive portion of the H.264 encoding process. Previous attempts to parallelize this algorithm in CUDA 1 showed sizable speedups but sacrificed quality by ignoring the motion vector prediction (MVp). We demonstrate the viability of a hierarchical (pyramid) motion estimation algorithm in CUDA. This solution addresses the MVp problem while...

Skin fibroblasts from patients with familial dysautonomia, Duchenne muscular dystrophy and Charcot-Marie-Tooth disease show normal sensitivity to ionising radiation, as measured by post-irradiation clonal growth. Previous reports of cellular hypersensitivity to ionising radiation and other DNA-damaging agents in familial dysautonomia and Duchenne muscular dystrophy have not been confirmed.

MVP is a framework allowing websites to use diverse knowledgebased authentication schemes. One application is its use in conducting ecologically valid user studies of authentication under the same experimental conditions. We introduce MVP and its key characteristics, discuss several authentication schemes, and offer lessons learned from running 9 hybrid (lab/online) and 3 MTurk user studies ove...

Methods Sixty-three children with benign joint hypermobility syndrome were included in case group and 63 without any rheumatologic disease were placed in control group. We used Carter-Wilkinson and Beighton criteria for diagnosing of benign joint hypermobility syndrome. MVP was evaluated by echocardiography in both groups. The mitral leaflet displacement >2 mm considered as cut off for diagnosi...

BACKGROUND Ventricular arrhythmias are common in patients with mitral valve prolapse (MVP). Previous studies have provided evidence that a higher degree of systolic mitral valve displacement and the presence of a thickened anterior mitral leaflet are related to an increased incidence of complex ventricular arrhythmias and risk of sudden death in these patients. The aim of our study was to inves...

© WILDLIFE BIOLOGY · 6:4 (2000) Even if the mean rate of population growth is positive, populations are in danger of becoming extinct if they are too small to buffer environmental and demographic fluctuations. But how small is 'too small'? Answering this question is important to guide management decisions in fragmented landscapes. Therefore, a major task of conservation biology is to determine ...

OBJECTIVE To determine cut-off values for amniotic fluid volume (AFV) predictive of fetal distress in pregnancies 40 weeks or longer, assessed using both amniotic fluid index (AFI) and height of the of maximal vertical pocket (MVP). METHODS Amniotic fluid index and MVP were evaluated in 100 women with pregnancies of 40 or more weeks and intact membranes using a 3.5-MHz linear transducer less ...
