Characteristics of strontium Strontium was discovered in 1790 in a mine close to the Scottish village Strontian and was isolated in 1808. Strontium is one of the alkaline earth metals and is never found in its free form in nature because it easily oxidises, forming strontium oxide. Strontium, along with calcium and magnesium belongs to group 2 of the periodic table which are divalent cations, w...

In previous work, oxidative metabolism in vascular smooth muscle was found to be correlated with isometric force; aerobic lactate production, however, was found to be substantial and correlated with Na-K transport processes (Paul et al., 1979; Paul, 1980). In this work, the role of glycogen phosphorylase in this unusual functional compartmentalization of of vascular energy metabolism was invest...

Dietary supplementation with calcium may prevent the development of colorectal cancer. This mechanism may be related to fatty acid and bile salt chelation in the small bowel forming non-toxic calcium-soap compounds. Calcium may also act locally or systemically on the colonic mucosa. Faecal concentrations of free fatty acids and free bile acids were measured in 17 Sprague-Dawley rats (weighing 4...

It has been suggested that glucagon-like immunoreactivity (GLI) of gastrointestinal tissues might, like pancreatic glucagon, have calcium-lowering activity. Studies were designed, therefore, to determine if calcium absorption was associated with GLI release from the gut. The intraduodenal administration of 4.5 mmoles of calcium chloride per kg of body weight to conscious dogs was associated wit...

The purpose of the work was to study changes in mineral composition, lactate content and pH oral fluid under influence high-intensity physical exertion on body students with different training. Materials methods. 28 who were divided into 2 groups, depending level training, took part study. Group 1 – attended only education classes. who, addition academic classes, sports sections 3-4 times a wee...

Strongly supersaturated homogeneous calcium citrate solutions are formed spontaneously when solid sodium citrate and solid calcium hydroxycarboxylates are dissolved simultaneously in water or when solid sodium citrate is dissolved in an already saturated aqueous solution of the calcium hydroxycarboxylate at ambient conditions. Maximal supersaturation of calcium citrate was found to decrease for...

Excessive calcium influx is important in the irreversible injury of cardiac myocytes and other cell types. The mechanism is unknown, but possibilities include L-type channels, Na(+)-Ca2+ exchange, sarcolemmal (SL) defects, and calcium leak channels. In this study, metabolic inhibition was used to induce ATP depletion and augmented calcium influx in cultured cardiac myocytes. Inhibition of the L...

A smooth muscle plasma membrane vesicular fraction (PMV) purified for the (Ca2+/Mg2+)-ATPase has endogenous glycolytic enzyme activity. In the presence of glycolytic substrate (fructose 1,6-diphosphate) and cofactors, PMV produced ATP and lactate and supported calcium uptake. The endogenous glycolytic cascade supports calcium uptake independent of bath [ATP]. A 10-fold dilution of PMV, with the...

Soymilk is one of the plant-based milk products containing great nutritional content and has an unpleasant beany flavour low calcium content. In this study, different grinding methods salts fortification were applied to improve flavour, content, stability soymilk upon addition. According results, preparing using anaerobic method significantly reduced lipid oxidation (0.4781 meq peroxide/kg) inc...
