This increased calcium concentration, in turn, triggers their transformation from a static to a mobile form, allowing them to begin sealing off the wound.

Schulz et al. (1993) found that although ingestion of both types of resistant starch lowered the cecal pH and increased the calcium concentrations in the liquid phase of the cecal contents, only ingestion of the native resistant starch lowered the ileal pH and increased the calcium and magnesium concentrations in the liquid phase of the ileal contents.

What is known is that calcium has a critical role to play — its concentration increases prior to glutamates release, but again the mechanisms are poorly understood.

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.

None of the sites showed a decrease in calcium concentrations in the organic layer, and a few showed an increase.

We observed similar robust increases of intracellular calcium concentrations in response to KCl and ATP in both GFP - expressing (n = 28) and GFP - nonexpressing cells (n = 12), whereas 5 - HT elicited an increase in intracellular calcium only in GFP - expressing cells (KCl: t (40) = 0.98, p = 0.33; ATP t (38) = 1.04, p = 0.30; 5 - HT: t (38) = 5.24, p < 0.0001 Student's t tests; Fig. 4A, B, F).

The exact mechanism how dopamine enhances hGH is still being researched, however experts believe that it does so by increasing another hormone called GHRH which acts by increasing intracellular calcium concentration in pituitary cells which secrete growth hormone.

Their exact conclusion was «an increase in serum calcium concentrations is associated with an increased risk of type 2 diabetes in individuals at high cardiovascular risk».

Obesity and obesity - related diseases increase the risk of prostate cancer (vegans weigh less than meat eaters), high concentration of IGF increase the risk of prostatecancer (higher level with animal fat and animal protein intake), dairy intake increase the risk of prostatecancer (IGF, high calcium intake).

Thanks to research over the past 15 years or so, we now know that the bitter taste receptors in our mouths release neurotransmitters that stimulate, via the vagus nerve, an increase in intracellular calcium concentrations.

Finally, acute changes in blood calcium concentrations do not seem to elicit the secretion of the phosphaturic hormone fibroblast growth factor 23 (FGF - 23), which is produced by bone - forming cells (osteoblasts / osteocytes) in response to increases in phosphorus intake (see the article on Phosphorus)(2).

High oxalate levels can increase the concentration of calcium or oxalate in urine, causing kidney stones to form.

This medication belongs to a group called positive inotropic agents which increase the concentration of calcium in heart muscle cells.

Other, but rarer, causes of metastatic calcification include kidney disease (this is the most common cause in cats), malignant tumors producing abnormal hormones that increase blood calcium concentrations (e.g. tumors of the lymphoid system and glands of the anal sac), diabetes mellitus and lung disease.

After 1 month on the treatment diet, intakes of moisture, sodium and fat were increased, and potassium and calcium intakes were decreased, and urinary calcium and oxalate concentrations and calcium oxalate RSS were decreased (Stevenson et al. 2004).

Some of these factors such as lower urine volume, higher calcium concentration and higher calcium oxalate RSS seen in small dogs may contribute to the increased prevalence of calcium oxalate urolithiasis in this group.

The cascade of events leading to calcium oxalate stone formation is largely unknown, but there is some indication that normal increases in urinary calcium concentration after feeding could be involved in stone formation.

Decreased urine concentration of natural body crystal formation inhibitors, and increased dietary intake of oxalate may also play a role in calcium oxalate stone formation.

Calcium absorption in the intestinal tract of rabbits is much higher than in other species and does not depend on vitamin D, so high - calcium diets may lead to increased blood calcium concentrCalcium absorption in the intestinal tract of rabbits is much higher than in other species and does not depend on vitamin D, so high - calcium diets may lead to increased blood calcium concentrcalcium diets may lead to increased blood calcium concentrcalcium concentrations.

Intuitively, it might be expected that the precipitation of calcium carbonate would decrease solution pCO2 and dissolution of calcium carbonate would increase pCO2 because total dissolved inorganic carbon (DIC) concentrations and total alkalinity (TA) change in this manner.

Elevated atmospheric CO2 is associated with decreased plant nitrogen concentration, and therefore decreased protein, in many crops, such as barley, sorghum, and soy.210, 211,212,213 The nutrient content of crops is also projected to decline if soil nitrogen levels are suboptimal, with reduced levels of nutrients such as calcium, iron, zinc, vitamins, and sugars, although this effect is alleviated if sufficient nitrogen is supplied.214 Fourth, farmers are expected to need to use more herbicides and pesticides because of increased growth of pests215, 216,217,218 and weeds219, 220 as well as decreased effectiveness221 and duration222of some of these chemicals (Ch.

«Prolonged exposure to moderate concentrations can cause acidosis and adverse effects on calcium phosphorus metabolism resulting in increased calcium deposits in soft tissue.

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).

Coral reefs are threatened by rising water temperatures, ocean acidification, and sea - level rise.3, 5 Coral reefs typically live within a specific range of temperature, light, and concentration of carbonate in seawater.6 When increases in ocean temperature or ultraviolet light stress the corals, they lose their colorful algae, leaving only transparent coral tissue covering their white calcium - carbonate skeletons.6 This phenomenon is called coral bleaching.
