A number of biochemical events accompany the development of chronic liver disease and its evolution into hepatic cancer. Low plasma zinc and high plasma copper levels have been observed in individuals with advanced hepatocellular liver disease. Moreover, many investigators have demonstrated an increase in serum estradiol levels in individuals with chronic(More)
Medical emergencies involving the gastrointestinal tract include bleeding, abdominal pain, diarrhea, toxic megacolon, pancreatitis, and hepatic failure. Each can be a cause for admission to an intensive care unit or occur de novo in a patient hospitalized in such a unit. The clinical presentation, management, and consequences of these varied(More)
The measurement of the correlation between the transverse spin components of + ? pairs collected during 1992 to 1994 with the DELPHI detector at LEP1 is presented. A value ? 0:12 (syst.) was obtained for the correlation parameter, in agreement with the Standard Model expectation.
A search for unstable heavy fermions with the DELPHI detector at LEP is reported. Sequential and non-canonical leptons, as well as excited leptons and quarks, are considered. The data analysed correspond to an integrated luminosity of about 48 pb 1 at an ee centre-of-mass energy of 183 GeV and about 20 pb 1 equally shared between the centre-of-mass energies(More)
Promptly decaying lightest neutralinos and long-lived staus are searched for in the context of light gravitino scenarios. It is assumed that the stau is the next to lightest supersymmetric particle (NLSP) and that the lightest neutralino is the next to NLSP (NNLSP). Data collected with the Delphi detector at centre-of-mass energies from 161 to 183 GeV are(More)
In an analysis of multihadronic events recorded at LEP by DELPHI in the years 1992 through 1994, charged hadrons are identiied using the measurement of their energy loss and their Cherenkov angle. Rapidity correlations of-, proton-proton, and-proton pairs are compared. The agreement with the string and cluster fragmentation models is tested. For those pairs(More)
Correlations between pions from diierent Ws in e + e ? !W + W ? events are studied using data collected by the DELPHI detector at LEP running at a centre-of-mass energy of 172 GeV in 1996. At the present level of statistics, no enhancement of the correlation function above that expected from a pair of uncorrelated Ws is observed at small values of the(More)
An inclusive measurement of the average multiplicity of b b pairs from gluons, g b b , in hadronic Z 0 events collected by the DELPHI experiment at LEP, is presented. A counting technique, based on jet b-tagging in 4-jet events, has been used. Looking for secondary bottom production in events with production of any primary avour, by requiring two b-tagged(More)
OBJECTIVE AND BACKGROUND Orthotopic liver transplantation is both a difficult and a demanding surgical procedure. It is not unexpected that cardiovascular dysfunction is present in some individuals being evaluated for liver transplantation. Thus, all potential liver transplant recipients seen at this center undergo a full cardiac evaluation prior to being(More)
