The intergalactic neutral hydrogen which is responsible for the Lyα forest of quasar absorption lines is a tracer of much larger amounts of ionised hydrogen. The ionised component has yet to be detected directly, but is expected to scatter CMB photons via the Sunyaev-Zel’dovich effect. We use hydrodynamic simulations of a LambdaCDM universe to create mock quasar spectra and CMB sky maps from th...
Many observations indicate the occurrence of ionised gas in the distant halos of galaxies (including our own). Since photoionisation by stars (mainly O stars, young or evolved low-mass stars depending on the kind of galaxy) does not seem to be exclusively responsible for the ionisation of the hydrogen filaments that should otherwise cool fast and recombine quickly, the question arises which ext...
A woman suspected of intra-abdominal bleeding with end-stage renal failure requiring maintenance haemodialysis was treated with continuous veno-venous haemodiafiltration in the intensive care unit. The use of citrate restricted to the extracorporeal circuit maintained continuity of treatment and avoided the adverse affects of systemic anticoagulation. Regional citrate anticoagulation was achiev...
Nine uraemic patients not being treated by dialysis received intravenous propranolol 1 microgram/kg/min for 85 minutes after a priming dose of 1 mg. Fifteen days later, six of them received intravenous metoprolol 1.2 microgram/kg/min after a priming dose of 1.2 mg. Plasma concentrations of parathyroid hormone (PTH) and calcitonin fell significantly after propranolol but not after metoprolol, wh...
