Based on our analysis of the behavior of standard UNIX communication software, we propose a new communication mechanism which reduces software overhead. This mechanism is optimized to be used in business applications, such as those of online transaction p r o c e s s i n g a n d d a t a b a s e m a n a g e m e n t. T h e s e applications are currently(More)
In our previous studies on sheep parotid secretory cells, we showed that the K+ current evoked by acetylcholine (ACh) was not carried by the high-conductance voltage- and Ca2+-activated K+ (BK) channel which is so conspicuous in unstimulated cells, notwithstanding that the BK channel is activated by ACh. Since several studies from other laboratories had(More)
Although acetylcholine (ACh) is able to activate voltage- and Ca2+-sensitive K+ (BK) channels in mouse mandibular secretory cells, our recent whole cell studies have suggested that these channels, like those in sheep parotid secretory cells, do not contribute appreciably to the conductance that carries the ACh-evoked whole cell K+ current. In the present(More)
As in other salivary glands, the secretory cells of the sheep parotid have a resting K+ conductance that is dominated by BK channels, which are activated by acetylcholine (ACh) and are blocked by tetraethylammonium (TEA). Nevertheless, perfusion studies indicate that TEA does not inhibit ACh-evoked fluid secretion or K+ efflux from intact sheep parotid(More)
