Diffusion of calcium ions in retinal rods. A theoretical calculation
نویسندگان
چکیده
The Fick diffusion equation is combined with the Langmuir adsorption isotherm and the relevant equations from the Gouy-Chapman theory of the electrical diffuse double layer to demonstrate that the effective diffusion coefficient of calcium ions, both in the cytoplasm of the rod outer segment and within the aqueous space bounded by the disk membrane, should be reduced by a factor of 10-100 because these ions adsorb to phospholipids present in the disk membrane.

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 کاملStructural investigation of complexes formed by DNA+CTAB and DNA+DDAB and Designing a method to increase salt ions between DNA and the Surfactant rods.
The internal structure of DNA-CTAB and DNA-DDAB is investigated by a Small Angel X- ray Scattering(SAXS) instrument. Hexagonal packing of DNA was observed for DNA complex with CTAB, and for DDABcomplex is observed lamellar structure. Variations in the internal spacing and degree of long-range ordering aredependent on both surfactant type and concentrations of added salt. When we increased the a...
متن کاملMorphology of retinal photoreceptor layer in continuous light-exposed and dark-adapted male cats
The morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (Felis catus). The eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. Results showed that the general structure of photoreceptor layer in this...

متن کاملCa2+ Diffusion through Endoplasmic Reticulum Supports Elevated Intraterminal Ca2+ Levels Needed to Sustain Synaptic Release from Rods in Darkness.
UNLABELLED In addition to vesicle release at synaptic ribbons, rod photoreceptors are capable of substantial slow release at non-ribbon release sites triggered by Ca(2+)-induced Ca(2+) release (CICR) from intracellular stores. To maintain CICR as rods remain depolarized in darkness, we hypothesized that Ca(2+) released into the cytoplasm from terminal endoplasmic reticulum (ER) can be replenish...
