Newly synthesized and non-toxic acyl derivatives of p-aminobenzoic acid were used as substrates indiagnostic kit for assay of cobalt-activated acylase activity. The enzyme activity, in serum of patients with viral hepatitis, depends on time, type and treatment of the disease and also on age and sex
The hepatitis B surface antigen, which constitutes the currently available vaccine, is the empty envelope of the hepatitis B virus. We investigated the carbohydrate structures of the envelope glycoproteins. The intact oligosaccharides were enzymatically released from the coat glycoproteins using
This work proposes a new strategy for the electrochemical detection of hepatitis C virus (HCV) RNA level and identification of HCV-1b genotype based on the site-specific cleavage of BamHI endonuclease combined with gold nanoparticles (AuNPs) signal amplification. The assay procedures include the
Exocrine pancreatic function was determined by oral administration of N-benzoyl-L-tyrosyl-p-aminobenzoic acid (peptic-PABA-test) in 120 controls, 74 patients with chronic pancreatitis, 35 patients with acute pancreatitis 2--6 weeks after recovery, 201 patients with a variety of gastro-intestinal
Synthetic oligonucleotides specifying amino acid sequences identified as epitopes of various foreign antigens (cholera toxin subunit B, hepatitis B surface protein and others) have been inserted at an EcoRV-EcoRV deletion site in a cloned Salmonella flagellin gene; the resulting plasmids, when
1. The activities of microsomal glucuronyltransferase and thiomethyltransferase, and those of cytosolic sulphotransferase, acetyltransferase, glutathione transferase and thiomethyltransferase were measured in abnormal (cirrhosis and chronic hepatitis) and normal livers. 2. Glucuronyltransferase and
