Functions of Calcium ions
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%...
متن کاملIncreased Binding of Calcium Ions at Positively Curved Phospholipid Membranes.
Calcium ion is the ubiquitous messenger in cells and plays a key role in neuronal signaling and fusion of synaptic vesicles. These vesicles are typically ∼20-50 nm in diameter, and thus their interaction with calcium ions cannot be modeled faithfully with a conventional flat membrane bilayer setup. Within our newly developed molecular dynamics simulations setup, we characterize here interaction...
متن کاملEstimating affinities of calcium ions to proteins
Ca(2+)-ions have a range of affinities to different proteins, depending on the various functions of these proteins. This makes the determination of Ca(2+)-protein affinities an interesting subject for functional studies. We have investigated the performance of two methods - Fold-X and AutoDock vina - in the prediction of Ca(2+)-protein affinities. Both methods, although based on different energ...
متن کاملInterphase Death of Chinese Hamster Ovary Cells Exposed to Accelerated Heavy Ions
Introduction: Heavy ions are nucleus of elements of iron, argon, carbon and neon that all carry positive electrical charges. For these particles to be useful in radiotherapy they need to accelerated to high energy by more than thousand mega volts. Also the cosmic environment is considered to be a complicated mixture of highly energetic photons and heavy ions such as iron. Therefore, the health ...
متن کاملIn 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 ...
