Several reports showing the presence of calcium carbonate (CaCO3) and calcium phosphate in renal stones suggested that crystals of those salts might be present in the early steps of stone formation. Such crystals might therefore promote CaOx crystallization from supersaturated urine by providing an appropriate substrate for heterogeneous nucleation.

2001-1-1 First, an approach was introduced whereby both nucleation and growth of calcium carbonate crystals are observed . In a second assay, growth of calcium carbonate crystals was monitored . Early investigations into the function of lithostathine, which at that time was called pancreatic stone protein, exclusively used the first assay .

2021-4-1 The difference in morphology between these three Ca-carb crystals is due to their crystalline structure: trigonal for calcite, orthorhombic for aragonite and hexagonal for vaterite. We can explain the differences between the three polymorphs from the different arrangement of the carbonate ions in their crystal structures.

2020-12-17 On stone, bacteria were found to form carbonate crystals, with only a few bacteria remaining as isolated cells or as cell aggregates. Pore size was reduced by about 50%, but no blockage was detected. Taken together, the results of this research provide some reassurance to conservators that biocalcification by bacteria could be a safe consolidation tool in a restoration strategy for building stone

Calcium carbonate crystals are large circular crystals with radial striations with smooth surfaces. Smaller versions form pairs and tetrads. The crystals are slightly brown. Other forms are the dumb-bell, oval and tetrad forms, which are seen in the background. This is the most common urine crystal in equine urine and imparts a cloudiness and brown ...

2021-4-1 1. Introduction. Crystalluria is the result of urine supersaturation with different types of salts the most frequent of which are calcium oxalate, calcium phosphate, and uric acid , .In normal subjects, supersaturation can transiently occur due to non-pathological high solute concentration, while in stone formers supersaturation is frequent and persistent over time , .

2021-6-17 Calcite, limestone and marble. Calcite: A mineral consisting largely of calcium carbonate (CaCO3 ). Next to quartz, it is the most abundant of the Earth's minerals. Crystallizing in the hexagonal system, calcite is noted for its wide variety of crystalline forms. Calcite is colourless or white when pure, but it may be of almost any colour ...

2001-1-1 INTRODUCTION. Chronic pancreatitis in most cases is accompanied by stone formation within the pancreatic duct system ().These stones primarily consist of calcium carbonate in the form of calcite (about 95% by weight) ().Based on in vitro assays, the pancreatic secretory protein lithostathine has been shown to have inhibitory activity against spontaneous calcium carbonate precipitation from ...

Carbonate. Gemstones Minerals. Malachite: Malachite is a bright green, basic copper carbonate. It appears as fibrous, radiating aggregates with silky to dull luster, and its crystals are adamantine. Acicular crystals are common. It commonly occurs as a green film on other copper minerals and as botryoidal or reniform masses with concretionary ...

Here we show that the carbonation of nanolimes in humid air at room T involves the initial formation of amorphous calcium carbonate (ACC) and its transformation into metastable vaterite (and minor aragonite) via a dissolution–precipitation process, followed by non-classical nanoparticle-mediated crystal

2021-6-18 That calcium and mucus is why even normal horse urine is often cloudy. But if the amount of calcium that needs to be excreted overwhelms that mucus production and finds a cluster of cells to grab on to, then a stone will begin to form. All herbivore urine also has a high pH (is alkaline) which precipitates formation of calcium carbonate stones.

The nonzero intercept reflects the solubility of calcium carbonate in "clean rain", that is, the solubility of calcium carbonate in water that is in equilibrium with atmospheric C0 2. The approximate intercept in Figure 1 of 0.13 mmol/L is at least 4 times lower than the predicted solubility of of 0.55 mmol/L, showing that the run-off solutions ...
