BABAR, the detector for the SLAC PEP-II asymmetric e þ e À B Factory operating at the Uð4SÞ resonance, was designed to allow comprehensive studies of CP-violation in B-meson decays. Charged particle tracks are measured in a multi-layer silicon vertex tracker surrounded by a cylindrical wire drift chamber. Electromagnetic showers from electrons and photons(More)
The analysis of 14-3-3 protein in cerebrospinal fluid (CSF) was shown to be highly sensitive and specific for the diagnosis of Creutzfeldt-Jakob disease (CJD). However, the predictive value of this test in the clinical diagnosis of, and its relation to, sporadic, genetic, and iatrogenic CJD cases have yet to be established. CSF samples of suspect CJD cases(More)
OBJECTIVE To assess the sensitivity, specificity, and interobserver reliability of periodic sharp wave complexes in the electroencephalograms of patients with Creutzfeldt-Jakob disease. DESIGN Sixty-eight electroencephalograms in 29 patients who had been suspected of having Creutzfeldt-Jakob disease were reanalyzed by an investigator who was unaware of(More)
Creutzfeldt-Jakob disease (CJD) is a rare, fatal, neurodegenerative disease caused by a transmissible agent designated as proteinaceous infectious agent (prion). Searching for biochemical markers of CJD, we analysed cerebrospinal fluid (CSF) samples of 53 patients for tau-protein using an enzyme linked immunoassay (ELISA). In a group of 21 patients with(More)
Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease caused by the human polyomavirus JCV. The hypervariable noncoding transcriptional control region (TCR) largely regulates replication of JCV in glial cells. Two distinct types of the TCR can be distinguished. Type II is derived from the archetype sequence. All type I TCRs,(More)
Neuron-specific enolase (NSE) is among the biochemical markers in cerebrospinal fluid reported to be useful in the differential diagnosis of Creutzfeldt-Jakob disease from other dementing illnesses. In a group of 58 patients with definite and probable Creutzfeldt-Jakob disease, NSE concentrations (median 94.0, interquartile range 256 ng/mL) were(More)
We evaluated S-100 levels in paired cerebrospinal fluid (CSF) and serum samples in a group of 135 patients referred to the German Creutzfeldt-Jakob disease (CJD) surveillance unit from June 1993 to May 1995. The patients were seen in a prospective case control study. The diagnosis of probable CJD during life was made in any patient presenting with rapidly(More)
We determined the cytokine messenger RNA (mRNA) expression pattern of blood mononuclear cells in 45 patients with the relapsing-remitting form of MS and 32 patients with other neurologic diseases. Using a semiquantitative polymerase chain reaction method, we detected significantly higher levels of tumor necrosis factor-alpha and lymphotoxin mRNA in patients(More)
