13. Degradação da interface de união utilizando diferentes sistemas adesivos em dentes deciduos e permanentes tratados endodonticamente : estudo in vitro / Bonding degradation in endodontic treated permanent and primary teeth using different adhesive systems : an in vitro study
During the endodontic treatment irrigant substances with the purpose of assisting the disinfection of the ducts are used, being the most used the sodium hypochlorite. These substances modify the teeth substrata, which is used in the formation of the hybrid layer and bonding of the adhesive systems to the dentine. The studies are controversial of the shear bo

14. Ecologia do bicudo-do-algodoeiro Anthonomus grandis Boheman, 1843 (Coleoptera:Curculionidae) no Cerrado do Brasil Central
The boll weevil Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae), one of the main pests of cotton, was introduced in Brazil in 1983. It causes the most serious damage to the crop, such as the falling of the flower buds, destruction of bolls and reduced linter production. The serious pest status of the boll weevil is mainly due to its high reprodu

15. Pescadores e turistas em uma área marinha protegida: uma contribuição ao planejamento da Reserva Extrativista Marinha da Ponta do Corumbau, Bahia - Brasil.
Marine-coastal areas in the South of Bahia State in Brazil has experimented environmental and social changes, related to the over-exploitation of the fishery stocks and to the overflow of carrying capacity of the bathing resorts. Most of traditional communities are migrating out forced by the oppressive tourism economy, leaving fishery and facing cultural an

16. Avaliação numérica do comportamento à fratura de um protótipo de vaso de pressão de reator PWR submetido a choque térmico pressurizado / Numerical evaluation of the fracture behavior of a PWR reactor pressure vessel prototype under pressurized thermal shock
In the primary system of a pressurized water reactor (PWR) nuclear power plant, the reactor coolant is kept at internal temperature around 300 C and internal pressure in the order of 15,0 MPa, during normal operation. The reactor pressure vessel (RPV) contains the fuel assemblies and is considered the most important component of the reactor primary system. T

17. Comportamento dos sistemas adesivos com fluor frente ao desafio cariogenico
The aim of this study was to investigate the behavior of fluoride-free and fluoride-containing adhesive systems subject to dynamic chemical induction of secondary caries, by means of the microtensile bond strength test, establishment of carious lesion depth and the amount of fluoride-ion release from each adhesive system. Eighty extracted bovine incisors wer

18. Evaluation of the central effects of yangambin isolated from Ocotea duckei Vattimo: Behavioral and neurochemical study in mice motor cortex and striatum / Avaliação dos efeitos centrais da iangambina isolada de Ocotea duckei Vattimo: Estudo comportamental e neuroquímico em córtex motor e corpo estriado de camundongo
The effects of the acute administration of yangambin (25, 50 and 75 mg/kg intraperitoneal and oral), were studied in some animals behavioral models (open field, rotarod, forced swimming test, barbiturate-induced sleeping time, hole board, elevated plus maze, pentilenotetrazole-induced convulsion). Binding in vitro with differents concentrations of yangambin

19. Sintomas musculo-esqueleticos relacionados ao trabalho em cirurgiões-dentistas
The purpose ofthe present research was to contribute for the knowledge ofmusculoskeletal disorders in Brazilian dentists, represented by a sample. That s why; we intended to identify the prevalence of musculoskeletal symptoms to the dentist work, as well as bis corporallocation, quality oflife aspects and odontological tasks perceived as stressfull. 165 dent

20. Floristica, espectro biologico e padrões fenologicos do cerrado sensu lato no Parque Nacional das Emas (GO) e o componente herbaceo-subarbustivo da flora do cerrado sensu lato
The cerrado, a savanna-like ecosystem, is the second largest vegetation type in Brazil. Among the reserves that protect it, Emas National Park (ENP) is one of the largest and best preserved. The ENP, with about 132,000 ha, is located in the Brazilian Central Plateau, southwestem Goiás State, under warm and wet tropical climate with three dry months in winte

21. Projeto de sistema de proteção de edificações contra descargas atmosféricas assistido por computador
Currently, due to the high number of lightning strokes that occur each year, has been a growing number of people interested in protecting equipment and facilities, the damage caused by them. As a support to develop effective systems for lightning protection, designers use the Brazilian Standard for Lightning Protection. The text of the standard features howe

22. Estrogen inhibits the vascular injury response in estrogen receptor β-deficient female mice
The protective effects of estrogen in the cardiovascular system result from both systemic effects and direct actions of the hormone on the vasculature. Two estrogen receptors have been identified, ERα and ERβ. We demonstrated previously that estrogen inhibits the response to vascular injury in both wild-type and ERα-deficient mice, and that ERβ is expres

23. Suppressed smooth muscle proliferation and inflammatory cell invasion after arterial injury in elafin-overexpressing mice
Elastases degrade the extracellular matrix, releasing growth factors and chemotactic peptides, inducing glycoproteins such as tenascin, and thereby promoting vascular cell proliferation and migration. Administration of serine elastase inhibitors reduces experimentally induced vascular disease. The ability to mount an intrinsic anti-elastase response may, the
