Solubility of calcium phosphates.
Solubil ity is one of the most important properties of calcium phosphate salts. It is the solubil ity that determines the direction of many reactions that involve calcium phosphates such as dissolution, precipitation, hydrolysis, and phase transformation. Calcium phosphate solubil ity also plays a maior role in biological processes that involve formation and resorption ol' hard tissues as well ...
متن کاملCitric acid and calcium metabolism.
Recently there has been increasing realisation of tile important part played by citric acid in the body’s metabolism. Thus administration of pyruvic acid, the intermediate metabolite common to the utilisation of carbohydrate, protein and perhaps fat, causes increased urinary excretion of citrate. Many tissues can form citrate by condensation of pyruvate and oxalacetate followed by reduction, an...
متن کاملRegulation of citric acid cycle by calcium.
The relationship of extramitochondrial Ca2+ to intramitochondrial Ca2+ and the influence of intramitochondrial free Ca2+ concentrations on various steps of the citric acid cycle were evaluated. Ca2+ was measured using the Ca2+ sensitive fluorescent dye fura-2 trapped inside the rat heart mitochondria. The rate of utilization of specific substrates and the rate of accumulation of citric acid cyc...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولModeling the Solubility of Acid Gases in Ionic Liquids
In this work, the PC-SAFT equation of state (EoS) has been used to model the solubility of acid gases (CO2 and H2S) in two imidazolium-based ionic liquids (ILs) ([C8-mim][PF6] and [C8-mim][Tf2N]). Parameters of pure ILs were estimated using experimental densities. Two strategies were considered to model densities of pure ILs. In strategy 1, ILs were modeled as nonassociating compounds and in st...
