13. Evaluation of retropreparations carried out with smooth ultrasound, diamond coated and no polished tips / "Avaliação de retropreparos confecionados por pontas de ultra-som lisas, diamantadas e despolidas"
Given the advantages of the use of ultrasound in the preparation of retrograde cavities, the present study evaluated the smooth, diamond -coated and use of no polished tips regarding the time required for the preparation of cavities, the presence of dirt and the penetration of the 0,2% rhodamine dye solution. After the apicectomy and endodontic treatment of

14. MULTIPLICAÇÃO IN VITRO DE MAMOEIRO TAINUNG 01
Experiments were accomplished in establishment and multiplication medium with the objective of evaluating the micropropagation of the papaya tree (Carica papaya L.) Hybrid Tainung 01 , generation F1, being used apical sections and apical sections of lateral buds of juvenile plants, cultivated in greenhouse. In the MS establishment medium, being used apical s

15. Estudo in vivo da infiltração coronaria em dentes de cães tratados endodonticamente e protegidos por diferentes materiais / In vivo study of the coronal leakage in endodontically treated dog s teeth protected by different materials
This in vivo study evaluated the microbial coronal leakage in dogs endodontically treated teeth, post space preparation and with the remaining filling protected or not with different materiais. A hundred thirty six root canais of incisives and pre-molars of 6 dogs were used. After the anesthesia of the animais, these teeth were endodontically prepared. Hundr

16. Análise "in vitro" da microinfiltração em retrobturação, utilizando diferente materiais retrobturadores e a influência da aplicação da Edta na cavidade retrógrada
Although reaching high success rates there is a great number of root canals endodontically treated which dont reach the wished results. In these cases there is necessity to indicate the periapical surgery. Among the surgical kinds the most used is the conventional retrograde filling. This surgical modality has also impelled the main researches about the matt

17. Avaliação da qualidade do selamento apical de obturações endodonticas em dentes preparados com alargamento intencional do forame
The aim of this study was to test ín vítro the apical sealing ability of endodontically treated human teeth prepared with intentional foramen enlargement. The root canals were prepared by conventional technique and filled by the lateral condensation with gutta-percha points and Endomethazone sealer. The teeth were coated with nail varnish layers, except th

18. The Mechanics of Left Ventricular Contraction in Acute Experimental Cardiac Failure*
The effects of acute cardiac failure induced by pentobarbital or pronethalol on the basic mechanical properties of the intact left ventricle were examined in the dog, and the influence on auxotonic and isovolumic contractions of the increase in end-diastolic volume that usually accompanies cardiac failure was assessed. The right heart bypass preparation was

19. Tethered particle motion method for studying transcript elongation by a single RNA polymerase molecule.
Schafer et al. (Nature 352:444-448 (1991)) devised the tethered particle motion (TPM) method to detect directly the movement of single, isolated molecules of a processive nucleic acid polymerase along a template DNA molecule. In TPM studies, the polymerase molecule is immobilized on a glass surface, and a particle (e.g., a 0.23 microns diameter polystyrene b
