Adenosine 5′-triphosphate (ATP) is an extracellular signal that regulates various cellular functions. Cellular secretory activities are enhanced by ATP as well as by cholinergic and adrenergic stimuli. The present study aimed to determine which purinoceptors play a role in ATP-induced changes in the intracellular concentration of calcium ions ([Ca2+]i) and(More)
Protease-activated receptors (PARs) represent a novel class of seven transmembrane domain G-protein coupled receptors, which are activated by proteolytic cleavage. PARs are present in a variety of cells and have been prominently implicated in the regulation of a number of vital functions. Here, lacrimal gland acinar cell responses to PAR activation were(More)
The main contribution of this paper is to present a simple, scalable, and portable tiny processing system which can be implemented in various FPGAs. Our processing system includes a 16-bit processor, a cross assembler, and a cross compiler. The 16-bit processor runs in 89 MHz on the Xilinx Spartan-3A family FPGAXC3S700A using 336 out of 5888 slices(More)
