AIMS To determine a possible mechanism to explain the presence of aluminium lines within fully calcified bone in aluminium-related osteomalacia. METHODS Fifty five bone cases shown by bone biopsy to be aluminium-related osteomalacia were studied. In 38 specimens aluminium lines were identified within calcified bone by means of the Aluminon stain and a characteristic form of patchy mineralisat...

BACKGROUND AND OBJECTIVES beta-thalassemia is an important public health problem in the countries bordering the Mediterranean sea. One of the major consequences of this disorder, primarily (due to an ineffective erythropoiesis) or secondarily to blood transfusions (which are necessary for the patient's survival), is iron storage. Applying X-ray microanalysis we wanted to demonstrate the differe...

A series of mesoporous silicas impregnated with nanocrystalline sulphated zirconia was prepared by a sol-gel process using an ionic liquid-templated route. The physicochemical properties of the mesoporous sulphated zirconia materials were studied using characterisation techniques such as inductively coupled optical emission spectroscopy, X-ray diffraction, transmission electron microscopy, ener...

Eight nonstandardized gutta-percha points commercially available in Brazil (Konne, Tanari, Endopoint, Odous, Dentsply 0.04, Dentsply 0.06, Dentsply TP and Dentsply FM) were analysed chemically and by X-ray diffraction, and their chemical compositions were compared. The organic fraction (gutta-percha polymer and wax/resin) of the gutta-percha points was separated from the inorganic fraction (ZnO...

Various genetic and morphological types of voids in carbonate reservoirs make it difficult to diagnose them, which can be seen the determination reservoir properties northern marginal shear zone Caspian Syneclise. A macro- microscopic study rocks was carried out by staining carbonates thin sections with alizarin (determination mineral composition, structure, texture, void fracture spaces, rock ...
