Feeding Response in Aedes aegypti: Stimulation by Adenosine Triphosphate
Taste receptors which evoke ingestion of blood in the mosquito, Aedes aegypti L., are stimulated byAdenosine tetraphosphate, adenosine triphosphate; no other nucleotide is effective, but certain chelators can partially simulate the effect of nucleotides.

SUMMARY: The turbidity of suspensions of various Gram-negative bacteria is affected by the tonicity of the suspending medium. The light extinction of the suspension increases in a nearly exponential…
Betaine-induced stimulation of respiration at high osmolarities in a halotolerant bacterium.
The above observations suggest that iso-economic adjustment is not involved in the anti-osmotic effect of betaine, and that betaine exerts its action on the cellular membrane from the outside.

New data obtained by 23Na nuclear magnetic resonance spectroscopy are presented, showing that the intracellular concentration of Na+ the halophilic eubacterium Vibrio costicola is only 5 to 20% of that in the extracellular medium.
Temperature-dependence of activation and inhibition of rat-brain adenosine triphosphatase activated by sodium and potassium ions.
Where oligomycin increased the activity of the enzyme, it also enhanced the accumulation of an acid-precipitable phosphorylated compound formed through the transfer of the gamma-phosphate group of [(32)P]ATP to the enzyme system.

The rapid adjustment of the turbidity (increase or decrease) to the changes in osmotic pressure of the medium was followed by a phase of slow decline in light extinction, which varied with the nature of the solute used; it was markedly accelerated by KCN or HgCl2.
An NADH:quinone oxidoreductase of the halotolerant bacterium Ba1 is specifically dependent on sodium ions.
Functional characterization of the uncoupler-insensitive Na+ pump of the halotolerant bacterium, Ba1.
