Adenosine has been demonstrated to inhibit gastric acid secretion. In the rat stomach, this inhibitory effect may be mediated indirectly by the inhibition of gastrin release. Results show that the A(1) receptor agonist N(6)-cyclopentyladenosine (CPA) suppressed immunoreactive gastrin (IRG) release in a concentration-dependent manner. CPA significantly(More)
Adenosine has been shown to inhibit immunoreactive gastrin (IRG) release and to stimulate somatostatin-like immunoreactivity (SLI) release by activating adenosine A(1) and A(2A) receptors, respectively. Since the synthesis and release of gastrin and somatostatin are regulated by the acid secretory state of the stomach, the effect of achlorhydria on A(1) and(More)
Providing quality healthcare in both rural and urban settings introduces many challenges. While today's Telemedicine attempts to address these challenges, the current approach is limited. This paper defines a new system architecture that leverages the network as the platform for intelligent transport and services to support high-definition videoconferencing(More)
