Most cases of hypercalcaemia are secondary to malignancy or primary hyperparathyroidism. We report a patient presenting with a triad of hypercalcemia, metabolic alkalosis, and renal failure secondary to treatment of iatrogenic hypoparathyroidism and osteoporosis. Persistent ingestion of calcium carbonate and vitamin D caused milk-alkali syndrome. The patient was managed with intravenous fluids ...

Red meat intake is associated with an increased risk of colorectal cancer. We have previously shown that haemin, Hb and red meat promote carcinogen-induced preneoplastic lesions, aberrant crypt foci (ACF), in the colon of rats. We have also shown that dietary calcium phosphate inhibits haemin-induced promotion and normalises faecal lipoperoxides and cytotoxicity. Unexpectedly, high-calcium phos...

A range of crystalline and nano-sized carbonate- and silicate-substituted hydroxyapatite has been successfully produced by using continuous hydrothermal flow synthesis technology. Ion-substituted calcium phosphates are better candidates for bone replacement applications (due to improved bioactivity) as compared to phase-pure hydroxyapatite. Urea was used as a carbonate source for synthesising p...

BACKGROUND Few interventions directly compare equivalent calcium and vitamin D from dairy vs. supplements on the same bone outcomes. The radioisotope calcium-41 ((41)Ca) holds promise as a tracer method to directly measure changes in bone resorption with differing dietary interventions. OBJECTIVE Using (41)Ca tracer methodology, determine if 4 servings/day of dairy foods results in greater (4...

Calcium carbonate aragonite polymorph nanoparticles derived from cockle shells were prepared using surface functionalization method followed by purification steps. Size, morphology, and surface properties of the nanoparticles were characterized using transmission electron microscopy, field emission scanning electron microscopy, dynamic light scattering, zetasizer, X-ray powder diffraction, and ...

The structure-directing influence of the organic dicarboxylates malonate, succinate, glutarate and adipate as templating species on the hydrothermal formation of CaCO(3) was investigated at different temperatures (60, 80, 90, 120, 150 and 190 degrees C) and with a range of molar ratios of [Ca(2+)]/[templating species] (20, 14.3, 10, 7.7, 5, 1, 0.5 and 0.33). In the presence of the dicarboxylate...

It has been estimated that under ordinary conditions from 5 to 10 per cent of all chicks hatched are weaklings that cannot be raised successfully to maturity and for this reason are destroyed by the intelligent poultryman. The cause of this condition has been attributed, 1, to a tendency of hens which have been laying heavily during the winter to lay eggs having weak germs the subsequent spring...

Carbonate sediments may be cemented by a variety of forms of aragonite. calcite. or dolomite. The mineralogy of the cement has been regarded by most investigators as the product of the physico-chemical environment within the sediment at the time of cementation. This has been a reasonable working hypothesis until it was recently demonstrated that many different kinds of cement may occur in beach...

With the aim of elucidating the details of enhanced oil recovery by surfactant solution flooding, we have determined the detailed behaviour of model systems consisting of a packed column of calcium carbonate particles as the porous rock, n-decane as the trapped oil and aqueous solutions of the anionic surfactant sodium bis-2-ethylhexyl sulfosuccinate (AOT). The AOT concentration was varied from...
