This paper studies the multistage pricing and seat allocation problems for multiple train services in a high-speed railway (HSR) with multiple origins and destinations (ODs). Taking the maximum total revenue of all trains as the objective function, a

We previously reported that PAC1 is expressed on ECL cells resulting in stimulation of [Ca(2+)](i), histamine and acid secretion. The study reported here characterized the signaling by PAC(1) on ECL cells; determined the effects of PACAP on the gastr

The ligands interacting with enterochromaffin-like (ECL) and parietal cells and the signaling interactions between these cells were investigated in rabbit gastric glands using confocal microscopy. Intracellular calcium concentration ([Ca2+]i) changes

The current study was undertaken to determine the presence and distribution of PAC(1)-Rs within the gastric mucosa. Polyclonal antibodies to the carboxyl terminus of the rat PAC(1)-R were generated and shown to be specific against the PAC(1)-R expres

Cholecystokinin (CCK)-A and CCK-B receptors are highly homologous members of the seven transmembrane domain G-protein-coupled receptor superfamily. Genes of both receptors contain five exons and share a similar exon-intron organization. To determine

BACKGROUND & AIMS: The cellular target for peptide YY (PYY) inhibition of gastric acid secretion is unknown. The aim of this study was to determine whether PYY inhibits histamine release from isolated enterochromaffin-like (ECL) cells by stimulation

Helicobacter pylori resists gastric acidity by modulating the proton-gated urea channel UreI, allowing for pH(out)-dependent regulation of urea access to intrabacterial urease. We employed pH- and Ca(2+)-sensitive fluorescent dyes and confocal micros

BACKGROUND & AIMS: Peripheral regulation of acid secretion depends mainly on stimulation or inhibition of the three major gastric endocrine cells (enterochromaffin-like, gastrin, and somatostatin). The aim of this paper was to define physiological re
