BackgroundProgressive autograft dilation and need for later reoperation remain major concerns of the Ross procedure. The study investigates clinical outcome after operation, including a longitudinal analysis dimensions over 25 years.MethodsFrom November 1991 to April 2019, 137 patients underwent procedure at University Hospitals UCL (Université catholique de Louvain)-Brussels Ghent. Inclusion c...

On 19 September 2012, what has so far been the largest known foodborne outbreak of gastroenteritis in Germany broke out in various schools and childcare establishments in the federal states of Berlin, Brandenburg, Saxony, Saxony-Anhalt and Thuringia. A total of more than 11,000 children and youths suffered from diarrhoea and vomiting. Epidemiological studies conducted by the Robert Koch Institu...

This paper presents some simulations of the proposed California power exchange, or pool, as it might interact with the regional market in the Western U.S. Pooling will increase interdependence with the regional market. We study this using a multi area chronological production simulation model. We find that overall operating economies resulting from pooling are small. Physical changes in the dis...

Nathan Berkovits Instituto de F sica Te orica, Univ. Estadual Paulista Rua Pamplona 145, S~ao Paulo, SP 01405-900, BRASIL e-mail: [email protected] The free action for the massless sector of the Type II superstring was recently constructed using closed RNS superstring eld theory. The supersymmetry transformations of this action are shown to satisfy an N=2 D=10 SUSY algebra with Ramond-Ramon...

as its first research and training centre and started work in Helsinki, Finland in 1985. The Institute undertakes applied research and policy analysis on structural changes affecting the developing and transitional economies, provides a forum for the advocacy of policies leading to robust, equitable and environmentally sustainable growth, and promotes capacity strengthening and training in the ...

As part of an ongoing research effort on separation assurance and functional allocation in NextGen, a controller-in-the-loop study with ground-based automation was conducted at NASA Ames’ Airspace Operations Laboratory in August 2012 to investigate the potential impact of introducing self-separating aircraft in progressively advanced NextGen time-frames. From this larger study, the current expl...

We present early-time Keck spectroscopic observations and late-time Hubble Space Telescope (HST) imaging of GRB000926. The HST images show a small offset between the optical transient and the compact host galaxy. Combined with the large equivalent widths measured for metallic absorption lines by the Keck Echellette Spectrograph and Imager (ESI) and the Low-Resolution Imaging Spectrometer (LRIS)...

BackgroundScarce data exist on differential opioid prescribing between men and women in the pre-, peri-, postoperative phases of care among patients undergoing total hip/knee arthroplasty (THA/TKA).MethodsIn this retrospective population-based study, Truven Health MarketScan claims were used to establish differences (1) year before THA/TKA surgery, (2) amount opioids prescribed at discharge, (3...

Double-negative T cells (DNTCs; ie, CD3(+)CD4(-)CD8(-) T cells) play a role in limiting chronic immune activation. GB virus C (GBV-C) infection is associated with reduced T-cell activation in human immunodeficiency virus (HIV)-infected individuals. T-cell activation and DNTCs were measured in HIV-infected subjects with a nondetectable HIV load. GBV-C-viremic subjects had significantly reduced C...
