13. Ramos colaterais do arco aórtico e suas principais ramificações em nutria (Myocastor coypus) = Collaterals brances of the aortic arch and its main rami in nutria (Myocastor coypus) / Collaterals brances of the aortic arch and its main rami in nutria (Myocastor coypus)
Background: Nutria (Myocastor coypus), also known as Swamp Beaver, is a medium-sized semiaquatic rodent that belongs to the Capromyidae family. Originally from the southernmost part of South America, the species is distributed in several parts worldwide such as Europe and United States, where it has been used for commercial purposes due to the excellent qual

14. Identificação molecular e caracterização estrutural de ciclotídeo de palicourea rígida com potencial inseticida
Over the years, there have been several discoveries of peptides containing a cyclic structural fold. Among these molecules the cyclotides family was reported, being composed of small cyclic peptides containing 6 (six) conserved cysteine residues, connected by disulfide bonds forming a cysteine binding cyclic structure also known as "Cyclic Cysteine Knot" (CC

15. Recuperação de urânio de rejeito de mina por meio de lixiviação alcalina / Recovery of uranium from mine wastes by alkaline leaching
Appropriate management of wastes is one of the most important environmental problems, particularly concerning the tailings of mining activities. Interim storage of the tailings at incorrect places pending treatment demands an urgent solution. The Osamu Utsumi Mine located in the city of Caldas, Minas Gerais, has faced such problem. The waste of the mine cons

16. Avaliação da influência do material obturador na resistência de união de retentor intrarradicular pré-fabricado fixado com resina, em dentes fragilizados, por meio do teste de push-out e MEV / Evaluation of the influence of filling material in the bond strength of a fiber-reinforced post fixed with composite resin in weakened teeth, by push-out test and SEM
Normalmente, a restauração de dentes tratados endodonticamente e com extensa destruição corono-radicular é um desafio para o clínico. Devido à facilidade de manipulação, resinas compostas fotoativadas têm se apresentado como boa opção para o reforço intrarradicular destes dentes, antes da fixação de pinos. O objetivo desta pesquisa foi avaliar

17. Adubação com N, P2O5 e K2O apenas em cobertura no crescimento de Eucalyptus urograndis na região do Pontal do Paranapanema-SP / Fertilizer N, P2O5 and K2O on growth of Eucalyptus Urograndis in the region of Pontal do Paranapanema
In a study performed at the field level by sector, we studied the effect of different levels of fertilization with nitrogen, phosphorus and potassium on the growth of Eucalyptus urograndis in relation to diameter at breast height (DBH), total height (H) and increase annual average (IMA m3.ha-1). The work was carried out at New District, Cuiaba Paulista-SP, i

18. Study of partition of ovomucoid protein in aqueous twophase systems and anionic or hydrophobic resins / Estudo da partição da proteína ovomucoide em sistemas aquosos bifásicos e em resinas aniônica ou hidrofóbica
In this work, the application of the liquid-liquid extraction technique with aqueous two-phase systems (ATPS) was evaluated for the separation of ovomucoid, an egg white protein. This technique is an advisable purification process applied to large scale since it provides a selective partition with high yields. The ATPS were composed by PEG 1500 and an inorga

19. Efeito do tempo e tipo de fotoativação e da ciclagem mecanica e termica na infiltração marginal de restaurações adesivas / Effect of light polimerization mode, time and mechanical and thermal load cycling on microleakage in adhesive restorations
The maintenance of the bond integrity between tooth and resin systems is important for the clinical success of composite resin restorations. Thus, the aim of this "in vitro" study composed of two manuscripts, was to evaluate the microleakage of Class II dental restorations: 1) made with an adhesive system and a dental composite, varying light curing time and

20. Moraceae Gaudich. de Viçosa, Minas Gerais, Brasil: florística e anatomia foliar de Ficus mexiae Standl / Moraceae Gaudich. of Viçosa, Minas Gerais, Brazil: floristic and leaf anatomy of Ficus mexiae Standl
The present work consists of the floristic study of Moraceae species in Viçosa, of the leaf anatomy, and the histochemical characterization of Ficus mexiae Standl., comparing with the anatomic data in the literature about F. enormis (Miq.) Miq., a species that is similar to F. mexiae. Viçosa is located in the southeastern Brazil, in the state of Minas Gera

21. Influence of different catilever extensions and glass or polyamaramid reinforcement fibers on fracture strength of implant-supported temporary
In long-term oral rehabilitation treatments, resistance of provisional crowns is a very important factor, especially in cases of an extensive edentulous distal space. The aim of this laboratorial study was to evaluate an acrylic resin cantilever-type prosthesis regarding the flexural strength of its in-balance portion as a function of its extension variation

22. Influência do modo de ativação e de uma restauração simulada de porcelana no grau de conversão e na dureza superficial de um cimento resinoso auto-adesivo de cura dual / Influence of polymerization mode and a simulated ceramic restoration on degree of conversion and surface hardness of a dual-cured self-adhesive resin cement
The aim of this study was to evaluate the degree of conversion (DC) and the microhardness of a self-adhesive resin cement under different activation protocols, immediately and after 24 hours of the beginning of the polymerization, and, defining cement regarding monomer composition, average diameter of the inorganic fillers and the percentage by weight of the

23. Influence of resin-composite formulation on the intra-oral degradation : in vitro study / Influencia da formulação de resinas compostas na resistencia a degradação intra-oral : estudo in vitro
Natural teeth, as well as restorations, are composed of materials that are subject to deterioration. Besides chemical, mechanical and thermo degradation, the formulation and post-cure composites network are dominant mechanism to determine the restorations longevity. The purpose of this study was to investigate the effect of materials formulation, light

24. Avaliação por microtração da resistência de união de diferentes sistemas adesivos ao esmalte humano
The objective of this work was to evaluate the microtensile bond strength to the human enamel of three different adhesive systems. Twenty one not prepared third molar human teeth (n=21) had been divided in three groups, with seven teeth in each group (n=7), as the used adhesive system: SB - Adper Single Bond 2 (3M/ESPE, St Paul, MN, the USA); CL - Clearfil I
