Functions of Calcium ions

چکیده
on earth.The body of healthy adult human body contains about 1250 gms of calcium.Calcium exist in three domains in vertebrate body :as a solid in the form of calcium phosphate which is the extracellular mineral component of the skeleton;in ionic and protein bound formin the blood and extracellular fluids;and intracellularly,inside the cell it is found in variety of fixed binding sites.About 99%is present in the skeleton as hydroxyappatite and the rest 1%inin the soft tissues and extracellular fluids.Normal plasma calcium level is about 10 mg%1.The amount of calcium bound to proteins varies with the total protein concentration as well as ph of the plasma.

In Vitro Evaluation of Calcium Ions Diffusion and ph Changes of the Periradicular Environment with Conventional Calcium Hydroxide and Synthetic Nanoparticle Calcium Hydroxide as an Intra-Canal Medicament
Background and Aim: Therapeutic effects of calcium hydroxide as an intra-canal medicament depend on its decomposition into hydroxyl and calcium ions. The aim of this study was to determine the diffusion amount of calcium ion and ph changes around the tooth root in the application of conventional calcium hydroxide and Nano particle calcium hydroxide at different times. Material and Methods: In ...
متن کاملStructure and functions of plant calcium-dependent protein kinases.
Calcium ions as second messengers play an essential role in many important cellular processes. In plants, transient changes in calcium content in the cytosol (calcium signatures) have been observed during growth, development and under stress conditions. Such diverse functions require many different calcium sensors. One of the largest and most differentiated group of calcium sensors are protein ...
متن کاملHydrophilic Natural Polymers for Sustained-controlled Release of Calcium Hydroxide
Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH chan...

One of the most important environmental problems is water and soil contamination with heavy metal ions. In this direction, the aim of this investigation was biosorptive removal of Cr (VI) using calcium alginate and determination of isotherm and kinetic of biosorption. Materials and Methods: Using batch system, biosorption capacity of calcium alginate for removal of Cr(VI) ions was investigated...
متن کاملCondition of pH and ionic composition of water in a macrophyte dominated reservoir (Hanna Reservoir- Isfahan Province), Iran
2/3 of the reservoir surface area was approximately covered with dense populations of Myriophyllum, Ceratophyllum and Potamogeton species. The headwaters of the reservoir were considered as hard water and had both carbonatic and non-carbonatic hardness. When they were exposed to lentic condition of the reservoir and its intensive photosynthetic activities of macrophyte communities, the bicarbon...
