25. Characterization of the Mandible Atta Laevigata and the Bioinspiration for the Development of a Biomimetic Surgical Clamp
Approximately thousand years ago it was reported the use of mandibles of ants for suture. In this sense, bioinspired components, as absorbable surgical clamps, can be designed. This study is aimed to characterize the mandible of the ant Atta laevigata in order to help the selection of candidate biomaterials for application as surgical clamps. Three pairs of

26. NOVOS HÍBRIDOS BASEADOS EM OXIHIDRÓXIDO DE FERRO(III) E NANOPARTÍCULAS DE OURO (AuNPs/FeOOH) COMO CATALISADORES PARA A REDUÇÃO DE POLUENTES ORGÂNICOS AMBIENTAIS
A new δ-FeOOH supported nano-Au catalyst was prepared by a facile method using HAuCl4 as the gold source and NaBH4 as the reducing agent. The samples (denoted as AuNPs/FeOOH) were characterized by means of X-ray diffraction (XRD), UV-vis and infrared spectroscopies and scanning electron microscope (SEM). The obtained characterization data confirmed the form

27. Comparative morphoanatomical analysis of Mikania species
ABSTRACT Mikania belongs to the Asteraceae family and includes a wide range of promising pharmacological activities. Several species of Mikania, which is popularly known in Brazil as “guaco”, occur in Southern Brazil and their external morphology is similar. The aim of this study was to investigate the morpho-anatomical characteristics of the leaf and st

28. Comparative morphology of two species of Caraguata Bechyné (Coleoptera, Chrysomelidae, Galerucinae, Galerucini)
ABSTRACT Caraguata Bechyné, 1954 (Galerucini, Galerucina) includes 38 species exclusively Neotropical, among them two sympatric species, C. atricornis (Clark, 1865) and C. guaporensis Bechyné, 1958. Given the lack of morphological studies in this group, we aimed to characterize the adult morphology of two species, providing descriptions, illustrations and

29. Immature stages of Temenis laothoe meridionalis Ebert (Lepidoptera, Nymphalidae, Biblidinae)
ABSTRACT The external morphology and life cycle of the immature stages of Temenis laothoe meridionalis Hübner, [1819] (Lepidoptera, Nymphalidae, Biblidinae), associated with Serjania laruotteana (Sapindaceae) in Curitiba, Paraná, Brazil, are described and illustrated with photographs and images from scanning electron microscopy. Special aspects of the exte

30. Redescription and first record in South America of Neogriphoneura timida Curran (Diptera, Lauxaniidae)
ABSTRACT The genus Neogriphoneura Malloch, 1924 is currently composed of 11 species with New World distribution. Neogriphoneura timida Curran, 1942 is recorded for the first time in South America, with occurrences in Brazil, Colombia and Trinidad and Tobago; and new Central American records are presented: Belize, Honduras and Mexico. Here we redescribe the s

31. Ag Nanoparticles-Based Zinc Hydroxide-Layered Hybrids as Novel and Efficient Catalysts for Reduction of 4-Nitrophenol to 4-Aminophenol
Silver nanoparticles and zinc hydroxide-layered hybrid materials (AgNPs/ZHL) have been successfully developed as efficient catalysts for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) with sodium borohydride. A facile and rapid visible-light assisted green route was used for the deposition of silver nanoparticles (AgNPs) on the external surfac

32. Taxonomic revision and phylogenetic relationships of Dasyloricaria Isbrücker & Nijssen, 1979 (Siluriformes: Loricariidae), with description of a new species
ABSTRACT A taxonomic revision and phylogenetic analysis were completed for Dasyloricaria . The genus includes three valid species: D . filamentosa and D . latiura previously included in the genus, and a new species described herein. Dasyloricaria have a restricted trans-Andean distribution, with D . filamentosa occurring at the lower and middle Magdalena, lo

33. Two new species of Mycodrosophila (Diptera, Drosophilidae) proposed by molecular and morphological approaches, with a key to American species
ABSTRACT There are approximately 130 species of MycodrosophilaOldenberg, 1914 worldwide, although only nine species were recorded in American countries so far, three of which are exclusively Nearctic, five exclusively Neotropical and one found in both biogeographic regions (Mycodrosophila projectans). Such a small number of American species is likely a conse

34. External morphology of immature stages of Zaretis strigosus (Gmelin) and Siderone galanthis catarina Dottax and Pierre comb. nov., with taxonomic notes on Siderone (Lepidoptera: Nymphalidae: Charaxinae)
ABSTRACT The external morphology of immature stages of Zaretis strigosus (Gmelin, [1790]) and Siderone galanthis catarina Dottax and Pierre, 2009 comb. nov. from southern Brazil are described. Additionally, morphology of the adults and sequences of the mitochondrial gene cytochrome oxidase, subunit I, were analyzed in order to evaluate the taxonomy of Sidero

36. Sodium hypochlorite effects on dentin bond strength and acid-base resistant zone formation by adhesive systems
Abstract Aim: To evaluate the effects of 10% NaOCl gel application on the dentin bond strengths and morphology of resin-dentin interfaces formed by three adhesives. Methods: Two etch-and-rinse adhesives (One-Step Plus, Bisco Inc. and Clearfil Photo Bond, Kuraray Noritake Dental) and one self-etch adhesive (Clearfil SE Bond, Kuraray Noritake Dental) were
