    Genetic similarity of iridoviruses from Japan and Thailand (1997)

    Notes: Iridovirus infection causes serious economic damage in marine cultured fish in Japan, Hong Kong and Singapore, and the incidence of this disease has been increasing. Iridovirus of sea bass from offshore Hong Kong was isolated to determine the genetic similarities of the causative agents. The genomic DNA of iridovirus was purified and cloned. Four DNA clones were randomly chosen and sequenced to generate primers for the polymerase chain reaction (PCR). Corresponding DNA fragments of iridoviruses from sea bass from offshore Hong Kong, red sea bream in Japan and grouper in Thailand were detected. The analogous PCR products from geographically diverse iridoviruses may indicate a widespread distribution of an iridovirus of a single origin.

    Notes: Summary We found that a receptor ligands differentially regulated the acetylcholine (ACh) neurotransmission in the rat brain. Acute administration of (+)-N-allylnormetazocine [(+)-SKF-10,047], a prototype σ1 receptor ligand, and 1,3-di(2-tolyl)guanidine (DTG), a non-specific σ receptor ligand, increased the extracellular ACh level in the rat hippocampus. This increase of hippocampal extracellular ACh level elicited by (+)-SKF-10,047 was more potent than that elicited by DTG. On the other hand, the striatal extracellular ACh level was slightly affected by (+)-SKF-10,047. In addition, DTG did not affect the striatal extracellular ACh level. Our previous studies have shown that both (+)-SKF-10,047 and DTG increased the extracellular ACh level in the rat frontal cortex. Taking all these data into consideration, the regulation of ACh neurotransmission by σ receptor ligands are different depending upon the brain region.

    Microcapsule formation in self-assembly of thermal heterocomplex molecules from amino acids (1996)
    Springer
    Colloid & polymer science 274 (1996), S. 899-903 
    Details
    ISSN: 1435-1536

    Notes: Abstract Solid microspheres that were phase-separated in aqueous suspensions of thermal heterocomplex molecules made by heating a mixture of proline and aspartic acid transformed into husk-like microcapsules as pH increased. The transformation from solid microspheres into microcapsules proceeded at two different time scales. Rapid dissolution of thermal heterocomplex molecules from the outer surfaces only during a short period was followed by slow dissolution of those molecules from their inside. The difference of the rates of dissolution led to the formation of microcapsules carrying smaller inner kernels as remnants.

    Diffusion controlled formation of husk-like microcapsules (1997)
    Springer
    Colloid & polymer science 275 (1997), S. 502-505

    Notes: Abstract  Solid microspheres consisting of thermal heterocomplex molecules made from heating a mixture of aspartic acid and proline were transformed into husk-like microcapsules in their aqueous suspensions when pH value increased. The thickness of the outer shell of the husk-like microcapsule decreased as pH increased. Formation of the husk-like microcapsules is discussed to be due to both diffusion of the constituent molecules from the inside of the microspheres and conformational changes of those molecules in the process.
