No full textThis study evaluated the Knoop hardness of one resin cement (dual-cure mode or light-cure mode) when illuminated directly or through restorative materials-ceramic (HeraCeram) or composite (Artglass)-by two light curing units. Light curing was carried out using a conventional quartz tungsten halogen (QTH) light source (XL2500) for 40 s, and a light emitting diodes (LED) light source (Ultrablue Is) for 40 s. Bovine incisors had their buccal faces flattened and hybridised. On these surfaces, a mould was seated and filled with cement. A disc of the veneering material (1.5 mm thickness) was positioned over this set for light curing. After storage (24 h/37 degrees C), samples (n = 10) were sectioned for hardness (KHN) measurements. Data were submitted to ANOVA and to Tukey's test (alpha = 0.05). In general, light curing with LED resulted in higher hardness values than QTH. Distinct cement behaviour was observed with different veneering material in association with different light curing units (LCUs). (C) 2006 Elsevier Ltd. All rights reserved.26226827

No full textIn 1906, German neuropathologist and psychiatrist Alois Alzheimer described eine eigenartige Erkrankung der Hirnrinde (a peculiar disease of the cerebral cortex). Alzheimer noted two abnormalities in autopsied brain tissue from his index case: senile plaques, proteinaceous structures previously described in the brain of normal elderly people; and abnormal cells delineated with silver stain that became known as neurofibrillary tangles (NFTs). The distribution and abundance of tangle-filled neurons are now the main criteria used to diagnose Alzheimer disease (AD) at autopsy
