The ultrastructure of the intestinal epithelium in Oreochromis niloticus on a diet with different concentrations of zinc
(2004-01-01)
The effects of diets with variable zinc levels on the midgut epithelial cells were studied in Oreochromis niloticus L. One hundred and twenty fry of tilapia were apportioned into 4 experimental groups (I, II, III and IV ...

Effect of different radiopacifying agents on the physicochemical properties of white portland cement and white mineral trioxide aggregate
(2012-03-01)
Introduction: The aim of this study was to evaluate the pH, calcium ion release, setting time, and solubility of white mineral trioxide aggregate (WMTA) and white Portland cement (WPC) combined with the following radiopacifying ...
Physico-chemical properties of MTA and a novel experimental cement
(2005-07-01)
Aim: To evaluate the release of calcium ions, pH and conductivity of a new experimental dental cement (EC) and to compare them with those of mineral trioxide aggregate (MTA-Angelus). Methodology: Five samples of each cement ...

Role of metal ions on the activity of Mycobacterium tuberculosis pyrazinamidase
(American Society of Tropical Medicine and Hygiene, 2012)
Pyrazinamidase of Mycobacterium tuberculosis catalyzes the conversion of pyrazinamide to the active molecule pyrazinoic acid. Reduction of pyrazinamidase activity results in a level of pyrazinamide resistance. Previous ...
