Introduction Carvedilol reduces rates of variceal bleeding and rebleeding by lowering portal pressure. However, an associated pleotropic survival benefit has been proposed. We aim to investigate further undertaking long-term follow-up a multicentred randomised control trial. Methods The index study 64 cirrhotic patients with clinically confirmed acute oesophageal between June ...

There is a long-standing debate on the role of genetic factors influencing homosexuality because the presence of these factors contradicts the Darwinian prediction according to which natural selection should progressively eliminate the factors that reduce individual fecundity and fitness. Recently, however, Camperio Ciani, Corna, and Capiluppi (Proceedings of the Royal Society of London, Series...

Atomic surface tensions are parameterized for use with solvation models in which the electrostatic part of the calculation is based on the conductor-like screening model (COSMO) and the semiempirical molecular orbital methods AM1, PM3, and MNDO/d. The convergence of the calculated polarization free energies with respect to the numerical parameters of the electrostatic calculations is first exam...

Wrong-side/wrong-site, wrong-procedure, and wrong-patient events are likely more common than realized, with little evidence that current prevention practice is adequate. DESIGN Analysis of se...
