Transcatheter aortic valve replacement failure: déjà vu ou jamais vu?

T he past half decade has seen transcatheter aortic valve replacement (TAVR) emerge as the standard of care for inoperable and high-risk patients with severe aortic stenosis: randomized data have demonstrated reduced mortality with TAVR compared with medical therapy or surgery in these respective situations. Accordingly, recent research efforts have reorientated from establishing the short-term...

A conserved Bach current

The Bach tensor and a vector which generates conformal symmetries allow a conserved 4-current to be defined. The Bach 4-current gives rise to a quasilocal 2-surface expression for power per luminosity distance in the Vaidya exterior of collapsing fluid interiors. This is interpreted in terms of entropy generation. PACS numbers: 0420J, 0440N

1.5% agarose gel stained with ethidium bromide. The seroprevalence rate in the first set of virus neutralization assays in Vero cells was 14/20 (70%, with titers ranging from 1:20 to 1:320 [3x1:20, 3x1:40, 3x1:80, 2x1:160, 3x1:320]). No differences were discernible in either the seroprevalence rate or in the average titers of crocodiles from two different breeding farms. In BHK cells, a similar...

Functional neuroimaging of narcolepsy 27 Thien

Introduction Functional neuroimaging techniques used to study narcolepsy include single-photon emission computed tomography (SPECT), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI). SPECT shows the distribution of radioactive isotopes, the decay of which is associated with the emission of detectable single gamma photons. Examples of SPECT isotopes are techne...
