Intracellular calcium and hydrogen ions in diabetes mellitus.
Diabetes mellitus is a multi-component syndrome that is often complicated by angiopathy which is partly due to enhanced platelet functions. Using fluorescent dyes 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein (BCECF) and Fura-2 AM, changes was evaluated in the concentration of baseline and thrombin-stimulated increases in intracellular ionized calcium (Ca2+i) relative to hydrogen ions in the ...
متن کاملHydrogen sulfide promotes calcium uptake in larval zebrafish.
Hydrogen sulfide (H2S) can act as a signaling molecule for various ion channels and/or transporters; however, little is known about its potential involvement in Ca(2+) balance. Using developing zebrafish (Danio rerio) as an in vivo model system, the present study demonstrated that acute exposure to H2S donors increased Ca(2+) influx at 4 days postfertilization, while chronic (3-day) exposure ca...
متن کاملThe initial velocities of calcium uptake by rat liver mitochondria.
Initial velocities of energy-dependent Ca++ uptake were measured in rat liver mitochondria by stopped flow techniques and dual wave length spectroscopy in the presence of the Ca++ indicator murexide. The initial rate of energy-dependent Ca++ uptake by mitochondria was 0.1 to 0.3 nmole per s per mg of protein at 5 to 15 pM Ca++, and increased to 8.2 nmoles of Ca++ per s per mg at 200 PM Ca++. Wh...
متن کاملThe effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders
Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...
