Intravenous calcium gluconate is a chelating agent that can be administered to a patient with a variety of medical conditions. Its bioavailability is influenced by the metal ion and its interactions with antibiotics and other biological fluids. Several studies have examined the effect of intravenous calcium on Digoxin toxicity and the effect of intravenous calcium on serum calcium. Loke SC and Lambs L performed studies on the effect of intravenous calcium in patients with secondary hyperparathyroidism and parathyroidectomy.
A chelating agent can increase the amount of calcium ions in a solution. A chelating agent, such as calcium phosphate, can act on a variety of metals. The k constant, or the equilibrium constant, describes the relative stability of the metal and the chelating agent. The lower the k constant, the less accessible the metal is.
Chelating agents can be either organic or inorganic. They possess a "ligand" (a group of atoms that have a specific affinity to metal ions) that binds the metal ions. A chelator's properties are determined by the number of atoms that are bound to the metal ions. The chelating agent's net ionic charge determines its ability to penetrate the metal ions and be absorbed into the body. It is also important to consider how the chelator may be excreted from the body.
Calcium infusion into metal is thought to induce a constriction of isolated coronary vessels. However, it is not yet clear how calcium infusion causes this constricting effect. This is a complex question, with contradictory results. Some studies have found a direct vasoconstrictor effect of calcium in isolated coronary arteries, while others have found a vasodilator effect of calcium in the heart.
To investigate the mechanism of calcium infusion into metal, we exposed BEAS-2B cells to NiCl2 and NiO NPs. The NPs were characterized by X-ray photoelectron spectroscopy and photon cross correlation spectroscopy. We also examined the cell death and genotoxicity of NPs using FITC/PI staining. The NPs were found to be capable of inhibiting the degradation of metal through anodic and mixed type inhibition. Moreover, we investigated the intracellular ROS and calcium levels in these cells using Fluo-4 and DCFH-DA.
One method of calcium infusion into metals is through ion exchange. It involves exchanging a monovalent calcium ion for a divalent calcium ion attached to a resin. However, this method is expensive and produces waste salts. In addition, it may lead to a buildup of calcium on the metal surface.
