Anti-idiotypic antibodies (anti-Ids) have been successfully used to characterize and isolate receptors of several cell ligands. To prepare an immunological probe for identification of cellular components interacting with the hepatitis B virus (HBV), polyclonal antisera against a panel of five HBV-specific monoclonal antibodies (MAbs) were produced in(More)
A hepatitis B virus (HBV) binding factor (HBV-BF) was identified in normal human serum interacting with the pre-S1 and pre-S2 epitopes of the viral envelope located within the protein domains involved in recognition of hepatocyte receptor(s). This molecule was characterized as a 50-kDa glycoprotein showing an isoelectric point of 7.13 with a biological(More)
Previously, we identified an HBV binding factor (HBV-BF), a 50-kDa serum glycoprotein which interacts with HBV envelope proteins and which is also located in the membrane of normal human hepatocyte (A. Budkowska et al. (1993) J. Virol. 67, 4316). Here we show that HBV-BF is a neutral metalloproteinase which shares substrate specificity and properties with a(More)
The Multifunctional and Adaptive Meal Preparation Facility (MAMPF) is a versatile and adaptive kitchen system allowing even an inexperienced user to create ambitious dishes. On the hardware side, the system controls hotplates by regulating the temperature of heated regions to turn the attention to the food actually being heated instead of the hotplate.(More)
Selected biochemical investigations were performed in 53 stuttering children aged 5-12, and in control group of 22 clinically healthy, non-stuttering children aged 6-16. Sodium, potassium, calcium and magnesium ions in the serum were determined according to the pharmacopoeia++ "Zweites Arztneimittelbuch++ der DDR (1983)". A special anamnestic questionnaire(More)
