Density Functional Theory has made the study of biomaterials feasible in past years leading to better understanding causes and possible treatments related pathologies. Although it been successfully applied many fields, not yet consistently found its way into field pathological calcifications. An overview will be given studies where this technique order outline important contributions that can b...

Analyses of the principal known bases and acids of the feces in cases of infantilism in which excessive amounts of calcium are being lost, and comparison with cases which are normal in this respect, show that the fats, fatty acids, and volatile acids are not high, and lead to the conclusion that the loss of calcium is not secondary to the presence of large quantities of phosphates, fatty acids,...

It is well known that porphyrins can be adsorbed on to precipitates of calcium salts, and adsorption can take place under the most varying conditions. Thus, it has been shown that in certain diseases porphyrins are found to be adsorbed on to urinary sediments of calcium phosphates (Garrod, 1892; Dobriner, 1936; Sveinsson, Rimington, and Barnes, 1949) and on to the bone and tooth tissue in mammals.

Osteomalacia is a metabolic bone disease in a mature individual, caused by lack of vitamin D or its active metabolites, on account of a number of factors. Osteomalacia is common in females and in countries with less sun shine. It typically presents with body aches, weakness, alongwith signs of bone tenderness and proximal myopathy. Diagnosis is made on the basis of clinical presentation and inv...

Previous studies suggested an increase in the proportion of calcium phosphates (CaP) of the total phosphorus (P) pool in soils with a long-term poultry manure application history versus those with no or limited application histories. To understand and predict long-term P accumulation and release dynamics in these highly amended soils, it is important to understand what specific P species are be...

Achieving adequate disinfection and preventing reinfection is the major goal in endodontic treatment. Variation canal morphology open porosity of dentine prevents achieving complete disinfection. Questionable biocompatibility materials as well a lack sealing ability questions usefulness current obturation methods. With novel approach based on use boron-doped diamond (BDD) electrodes having show...

This report presents a method for the quantitative determination of magnesium and calcium in a single specimen of urine, stool, and food by formation and calorimetric determination of their respective phosphates. The method makes use of some of the principles advanced by Roe and Kahn (1) for determination of serum calcium, and by Denis (2) for serum magnesium. Phosphorus determinations are perf...
