Hyaluronate from rooster comb was isolated by ion-exchange chromatography on DEAE-cellulose from tissue extracts and papain digests. The preparations were labelled with [14C]acetic anhydride and subjected to CsCl-density-gradient centrifugation in 4 M-guanidinium chloride in the presence and absence of 4% ZwittergentTM 3-12. A radioactive protein fraction was separated from the hyaluronate when...
Ideally, the ITER base blanket would provide the necessary tritium for the reactor to be self-sufficient during operation, while having minimal impact on the overall reactor cost, reliability and safety. A solid breeder blanket has been developed in the CDA phase in an attempt to achieve such objectives. The reference solid breeder base blanket configurations at the end of the CDA phase has man...
Testing TBM (Test Blanket Modules) is one of important engineering test objectives in ITER project. China is performing the TBM design and R&D based on Chinese development strategy of fusion DEMO. Helium-cooled test blanket module concept with ceramic breeder for testing on ITER will be one of the basic options in China. The current progress and status on design and R&D of CH HC-SB (Chinese Hel...
Twenty strains of Venezuelan encephalitis (VE) virus inoculated intravenously in large doses into roosters produced hemagglutination-inhibition (HI) antibodies detectable in plasmas within 7 to 10 days. No signs of illness occurred, and there was no evidence of viral growth in tissues since blood concentrations of infectious virus steadily decreased after inoculation. HI antibodies in early pla...
In vitro transcription competition with oligonucleotides has shown that a down regulating factor can be displaced by a methylated oligonucleotide covering a specific region of the avian vitellogenin II gene promoter (Proc. Natl. Acad. Sci USA, (1990) 87, 3047-3051). Gel mobility shift and competition assays show that a protein binding preferentially to methylated DNA (MDBP-2) is present in frac...
this study was conducted to investigate the effect of aflatoxin b1 (afb1) on performance and egg quality in broiler breeders and the abatement of its deteriorative effect through its counteraction with herbal mycotoxin binder (hmb). thirty-six, 28-wk-old broiler breeder hens were allotted to one of the three treatments of: (1) basal diet (control),(2) control plus 500 μg kg-1 afb1 and (3) contr...
