The present study investigated the site of action of 5-hydroxytryptamine (5-HT) and pharmacologically characterized the receptors involved in regulating blood glucose levels in the crayfish, Procambarus clarkii. Injection of 5-HT into intact animals increased glucose levels in a dose-dependent manner. In contrast, 5-HT failed to elicit a hyperglycemic(More)

A mobile environment is weakly-connected, characterized by low communication bandwidth and poor connectiv-ity. Conventional paradigm for surrng mobile web documents is ineeective since p ortions of a document could be corrupted during transmission and it is expensive to re-transmit the whole document. It is important that the high content-bearing portions(More)
The presence, characteristics and localization of nitric oxide synthase (NOS) in the eyestalk ganglia of the crayfish (Procambarus clarkii) were investigated. Biochemical assay indicated that NOS activity was significantly inhibited by N(G)-nitro-L-arginine (a NOS inhibitor), fluphenazine-N-2-chloroethane (a calmodulin inhibitor) as well as by omitting(More)
Fueled la.rgely by the gaining popularity of World Wide Web (web) servers and browsers, more and more sites have published their databases to the Internet/Intranet. This allows users to retrieve and explore database items as "dynamic" HTML pages. Existing dynamic HTML pages are passive. When the content of a database is changed, the corresponding dynamic(More)
