Sentences with phrase «calcium ions increases»

The addition of very small quantities of calcium ions increases the viscosity considerably.

Not exact matches

«It is not yet known whether there's actually an increase or decrease in the flow of calcium ions through the channel,» Olesen says.

This leads to a large increase in the amount of a special calcium ion channel in the nerve cells and overall, this significantly boosts the risk of epileptic seizures.

Researchers discovered additional salt ions — potassium, magnesium, and calcium, among others — are also increasing in the country's freshwater rivers.

The increase in calcium ions is shown for a single experiment at pH = 9.25 (Fig. 1A).

The mutation resulted in a lower single channel conductance for calcium and a strongly increased conductance for sodium and potassium, indicating that glutamic acid - 95 is a crucial constituent of the ion selectivity filter.

However, the amount of free calcium ions detected by the calcium ion selective electrode (black line) increases considerably slower straight from the beginning of the experiment; that is, a distinct part of free calcium ions disappears due to binding.

The increasing fraction of carbonate ions in the buffer at higher pH promotes cluster formation and in this way increases calcium binding (principle of LeChatelier).

They then decided to see what would happen if they supplied nitric oxide while simultaneously supplying chemicals that increase levels of calcium ions in cells.

As temperature increases, these bonds break down and the double strands «unzip,» releasing the positively charged 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.

These, such as verapamil, diltiazem, nifedipine, nitrendipine and nimodipine are not only widely used to treat hypertension, and hence might affect cognition by increasing cerebral blood flow, but also block the entry of calcium ions into neurons.

Wolframin expression induces novel ion channel activity in endoplasmic reticulum membranes and increases intracellular calcium.

Acidification increases the corrosiveness of the water and is also driving a decline in the amount of carbonate ion, needed to make aragonite and calcite, two forms of calcium carbonate that many marine organisms use to build their shells and skeletons.

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).

The increased levels of carbonic acid in the water means there are less carbonate ions available in seawater for making shells, meaning that thousands of species that build shells or skeletons from calcium carbonate are in danger of extinction.

For example, when atmospheric concentrations of carbon dioxide increased in geologic times to a certain unknown threshold, it went into the ocean and combined with positively charged calcium ions to form calcium carbonate — limestone.

Increasing atmospheric CO2 concentrations lower oceanic pH and carbonate ion concentrations, thereby decreasing the saturation state with respect to calcium carbonate (Feely et al., 2004).

TA actually does increase slightly, but this is because some solid calcium carbonate dissolves under the more acid conditions to yield carbonate ions that then enter into the carbonate / bicarbonate balance.

The diurnal temperature changes led to changes in CO2 and therefore pH. Temperature increase and lower atmospheric pressure will lead to lower CO2 concentrations and hence pH. Acid rainfall on Calcium feldspars will lead to Ca2 + ions entering the oceans.
