1. A influência da fonte fotoativadora e de diferentes produtos de uso profissional sobre o clareamento de dentes desvitalizados : estudo ex vivo / The influence of light source and different products for professional use on the bleaching of devitalized teeth : ex vivo study
There are controversies about the use of light sources to accelerate the bleaching agents in teeth submitted to endodontic treatment. The objective of this study was to analyse quantitatively the bleaching ability of different products for professional use, photoactivated or not, on bovine teeth stained artificially. Fifty bovine incisor were divided on five

2. Cianotipia em grande formato : processo alternativo de reprodução de imagem em camara clara : uma abordagem das dimensões da linguagem, cor e espaço / Cyanotype in huge format : alternative process in bright chamber : a boarding of the dimensions of the language, color and space
A tecnologia alternativa de reprodução de imagens através do sistema de impressão negativo-positivo conhecida como Cianotipia possibilita, pela própria característica química dos sais de ferro fotossensíveis da emulsão, ou seja, sensibilidade à luz ultravioleta, a impressão à luz do Sol (rica em UV) por foto-contato, como uma câmara clara, de re

3. The distribution of blood cells on haemacytometer counting chambers with special reference to the amended British Standards Specification 748 (1958)
The distribution of leucocytes and erythrocytes on the haemacytometer counting chamber is shown. Differences between total leucocyte counts on single and double-ruled chambers are given and the effect of different lengths of cover glass are discussed. An assessment of the relative accuracy of the amended British Standards Specification (B.S.S.) 748 (1958) do

4. Atrial-like phenotype is associated with embryonic ventricular failure in retinoid X receptor alpha -/- mice.
We have recently characterized a cardiac model of ventricular chamber defects in retinoid X receptor alpha (RXR alpha) homozygous mutant (-/-) gene-targeted mice. These mice display generalized edema, ventricular chamber hypoplasia, and muscular septal defects, and they die at embryonic day 15. To substantiate our hypothesis that the embryos are dying of car
