Hyperphosphatemia is an inevitable consequence of end stage chronic kidney disease and is present in the majority of dialysis patients. Recent observational data has associated hyperphosphatemia with increased cardiovascular mortality among dialysis patients. Dietary restriction of phosphate and current dialysis prescription practices are not enough to maintain serum phosphate levels within the...

The calcic phosphates represent a complex family. Their conditions of crystallisation and inhibition were studied at various pH values. Phosphate precipitates obtained from artificial urine in the pH range (6.5; 7; 8) were identified using FTIR and XRD. At pH = 6.5 brushite accompanied by carbonated amorphous phosphate complexes precipitated while at pH = 7, the coexistence of brushite, struvit...

Current research indicates that lipid peroxidation could have a role in aluminium toxicity. The aim of this study was to asses lipid peroxidation and antioxidative enzyme activity in erythrocytes of workers occupationally exposed to aluminium. We investigated a group of 59 workers (Al group) exposed to aluminium fumes (contamination factor F=8.07 to 13.47, national maximal allowed concentration...

AIM OF THE WORK Aim of the work was to execute a review of the international literature about the cementation of zirconia restorations, analyzing the properties of the cements most commonly used in clinical activities. MATERIALS AND METHODS It was performed, through PubMed, a bibliographic search on the international literature of the last 10 years using the following limits: studies in Engli...

Biomaterials have evolved over the past three decades and are relatively specialized, highly biocompatible, but low-strength dental materials. Bioactive materials can interact with living tissues or systems. The newly emerging bioactive category of has expanded clinical uses in restorative dentistry endodontics. Examples Calcium Silicate containing Mineral Trioxide Aggregate (Portland cement); ...

Ten indigenous bacterial isolates were identified as efficient mineral phosphate solubilisers namely 7 strains of Klebsiella pneumoniae, 2 strains of Enterobacter aerogenes and 1 strain of Pseudomonas aeruginosa. All the ten strains were able to dissolve calcium phosphate (Ca-P), ferric phosphate (Fe-P) and aluminium phosphate (Al-P) efficiently. STMPSB 8 (Klebsiella pneumoniae) could be design...

The radioactive aluminium waste generated by the VVR-S nuclear reactor decommissioning after nearly 15 years from shut-down is represented as low and intermediate radioactive waste and is divided as activated and contaminated aluminium metal. To realize a conditioning matrix for radioactive aluminum is necessary to study alternative cementitious systems such as magnesium potassium phosphate cem...
