Four ADP-glucose pyrophosphorylase (AGP) cDNAs were cloned from tomato fruit and leaves by the PCR techniques. Three of them (agp S1, agp S2, and agp S3) encode the large subunit of AGP, the fourth one (agp B) encodes the small subunit. The deduced amino acid sequences of the cDNAs show very high identities (96-98%) to the corresponding potato AGP isoforms,(More)
OBJECTIVE To detect hepatitis C virus (HCV) RNA sequences in the hepatic portal cholangiocarcinoma tissues and their relationship. METHODS RNA was extracted from paraffin-embedded cholangiocarcinoma tissues of 6 patients by guanidinium method, subjected to reverse transcription and then amplified by double PCR technique using nested primers from the(More)
Levo-praziquantel is the left isomer of racemic praziquantel. Animal experiments showed that it is an active component of schistosomicidal activity, while dextro-praziquantel is almost ineffective. Clinical trials in three endemic areas of Schistosomiasis japonica indicated that the therapeutic efficacy of levo-praziquantel is superior to racemic(More)
AIM To establish an enzyme-linked immunosorbent assay (ELISA) for detection of IgG against penicillins and then investigate this antibody response in children. METHODS Western blotting, ELISA, and hapten inhibition assay were used. RESULTS Penicillins reacted with bovine serum albumin (BSA) to generate conjugate which was used as coating antigen (100(More)
The transmission of haemorrhagic fever with renal syndrome (HFRS) is influenced by climatic, reservoir and environmental variables. The epidemiology of the disease was studied over a 6-year period in Changsha. Variables relating to climate, environment, rodent host distribution and disease occurrence were collected monthly and analysed using a time-series(More)
1. Peptide fingerprints of tryptic digests of the globins of sea snake species of Hydrophis, Pelamis, Aipysurus, Laticauda and the terrestrial elapid Naja were compared. 2. Globin divergence, as estimated from peptide fingerprints, paralleled closely transferrin divergence, as measured immunologically. 3. Taxonomic affinities, suggested by the fingerprint(More)
Pseudomonas aeruginosa is a gram-negative opportunistic pathogen that is cytotoxic towards a variety of eukaryotic cells. To investigate the effect of this bacterium on monocyte, we infected human U937 cells with the P. aeruginosa strain in vitro. To explore the expression of Bcl-2 and Bax as well as caspase-3/9 activation in the apoptosis of human U937(More)
ADP-glucose pyrophosphorylase (AGP) was purified from tomato (Lycopersicon esculentum Mill.) fruit to apparent homogeneity. By sodium dodecyl sulfate-polyacrylamide gel electrophoresis the enzyme migrated as two close bands with molecular weights of 50,000 and 51,000. Two-dimensional polyacrylamide gel electrophoresis analysis of the purified enzyme,(More)
The intracellular location of ADP-glucose pyrophosphorylase (AGP) in developing pericarp of tomato (Lycopersicon esculentum Mill) has been investigated by immunolocalization. With the use of a highly specific anti-tomato fruit AGP antibody, the enzyme was localized in cytoplasm as well as plastids at both the light and electron microscope levels. The(More)
