The increase of mitral valve insufficiency associated with systemic lupus erythematosus (SLE) seems to be related to the treatment with corticosteroids. Corticosteroids heal Libman-Sacks endocarditis, but thereby they lead to fibrotic, retracted leaflet tissue and thus to severe valvular dysfunction. We present three patients with SLE who underwent mitral(More)
We have applied the Pipas-McMahon algorithm based on free energy calculations to the search for a 5S RNA base-pair structure common to all known sequences. We find that a 'Y' shaped model is consistently among the structures having the lowest free energy using 5S RNA sequences from either eukaryotic or prokaryotic sources. Compaison of this 'Y' structure(More)
Luminescence quenching of Ru(II) complexes by oxygen has proved a powerful method of quantitative oxygen analysis. It has become clear that the polymer support for the sensor molecule plays a pivotal role in the sensor performance. The current work is devoted to understanding how the physical and photophysical properties of a sensor respond to changes in(More)
BACKGROUND Although the demonstration of leptomeningeal dissemination is the most important predictor of poor outcome in children with medulloblastoma, there is lack of consensus on the prognostic value of a positive cerebrospinal fluid (CSF) cytology (i.e., stage M1). PATIENTS AND METHODS Eighty-six pediatric medulloblastoma patients treated in(More)
