Sentences with phrase «which calcium ions»

A key stage in the molecular cascade of memory formation appears to be the opening of membrane channels through which calcium ions flow.

SOCE is a process by which Calcium ions slowly enter cells to refill Calcium stores that have been depleted by various activities.

To better understand these processes, in which calcium ions interact with biological molecules such as proteins, researchers often use computer simulations.

Not exact matches

Hard water contains minerals, usually calcium and magnesium ions, which make soap less effective and leave scale on your dishes and plumbing.

The speed with which the wave moves suggests that it travels through gap junctions and is made up either of calcium ions or some other small signaling molecule.

If a simulation doesn't fully take these effects into account, it overestimates how strongly the calcium binds, producing ions that can't unbind, which is unrealistic.

Calcium ions then travel through the channel, switching on a synthetic piece of DNA the scientists developed to turn on the production of a downstream gene, which in this study was the insulin gene.

Sodium citrate comes in and replaces the calcium ions with sodium ions, which are less positively charged (sodium: +1; calcium: +2).

To maintain the solubility constant, which, however, slightly differs for the phases precipitated in different pH ranges, the solubility concentration of calcium ions is specifically lower at higher concentrations of carbonate (higher pH).

They used Arabidopsis thaliana (thale cress) plants that produce a special protein which breaks down after the binding of calcium ions and emits free energy in the form of light.

In order to visualize this signal, the scientists performed experiments with transgenic Arabidopsis plants which were genetically modified to express a protein in the cytosol, the liquid inside the cells, which breaks down and releases light energy after it has bound calcium ions.

Either the increased concentration of free calcium ions or their increased mobility (likely both, the researchers speculate) results in a decrease in the electrical resistance throughout the material, which can be detected with a multimeter connected to electrodes embedded in the film.

Neuronal activity is correlated with an influx of calcium ions, which can be tracked with fluorescent dyes or proteins that bind to calcium, as in these pyramidal cells.

Wolfram syndrome is caused by a mutation in the gene encoding a protein called wolframin, which resides in the membrane of the endoplasmic reticulum — another cellular compartment that functions as a manufacturing and packaging system and also acts as a reservoir for calcium ions.

They also showed that a calcium chelator, which binds any free calcium ions, prevented the expression of Nodal, one of the key left - right genes.

Building on those findings, the Jans identified the genes for a different family of channels called calcium - activated chloride channels, which shuttle chloride ions to control smooth muscle contraction in the stomach, intestines, and lung airways.

Calcium ions also allow neurons to signal one another, which ties in to the gut - brain - skin axis.

Titin is activated by calcium ions (Labeit et al. 2003; Cornachione et al. 2016), which are released in response to the action potentials that cause activation of muscle fibers.

Hard water is the opposite of soft water, which by its definition is surface water with lower concentrations of ions, such as calcium and magnesium.

Magnesium Sulfate reduces inflammation, relaxes muscles and blood vessels as well as modulates calcium ion channels within our cells, which trigger the release of neurotransmitters.

The proposed mechanism of action via which magnets might improve recovery include increased blood flow, changes in the migration of calcium ions, alteration of pH balance, changes in hormone production, and an alteration of enzyme activity (20).

Raw milk casein is made out of a complex group of protein clusters called micelles, which are bound with calcium, phosphate, and citrate ions and exist at a neutral pH of approximately 6.6, roughly the same as your body's pH. Native Micellar Casein complements your body's acid - base balance and will not cause an acidic effect.

Phytates (phytic acid) bind to metal ions, preventing the absorption of certain minerals, including calcium, magnesium, iron, and zinc — all of which are co-factors for optimal biochemistry in your body.

The propagation of the MAP leads to the release of calcium ions, which enables the muscle fiber to produce tensile force.

Within the cell, these calcium ions bind to activator proteins, which help release a flood of calcium ions from storage vesicles of the endoplasmic reticulum (ER) inside the cell.
