Given the complexity of the etiopathogenesis of the diseases that affect the periodontium, several mechanisms to support conventional periodontal therapy, based on non-surgical and surgical steps have been studied in the literature, including ozone in its various vehicles and with various purposes. The aim of this study was to describe the applications of ozone therapy in Periodontology, in the areas of surgical and non-surgical therapy from the viewpoint of molecular, cellular and tissue effects focused on the repair process. An integrative literature review was conducted using the Pubmed/MEDLINE and SciELO databases with the search terms ozone, periodontal disease and periodontal surgery associated with the Boolean operator and. After applying the eligibility criteria listed by the PRISMA-ScR strategy, 15 articles were selected for qualitative analysis in order to answer the following study question, developed by the PICO strategy: "What are the advantages of ozone therapy in periodontics from the microbiological, cellular and tissue repair points of view? It is perceived that ozone is a good adjunct to conventional periodontal therapy, due to its hemostatic, angiogenic, analgesic, anti-hypoxic and antimicrobial effects, in addition to impacts on the molecular signaling pathways of the inflammatory response, Although further studies are needed so that protocols for its application can be standardized based on clinical practice based on scientific evidence, given the potential for improvement in tissue repair and consequently in periodontal surgical recovery time, which unfolds to the quality of life of patients affected by periodontitis.

The present study had as objective to evaluate the resistance to torsion fracture of two instrumentation systems based on different motion cinematics: alternating movement of the system TF Adaptive and the rotary movement of the system HYFLEX CM. For this 15 TF Adaptive instruments were used  to 27 mm in length, with the following dimensions: 20/.04, 25/.06, 35/04 and 30 Hyflex CM instruments to 25 mm in length, with the following dimensions: 25/.08, 20/.04, 25/04, 20/.06 , 30/.04 and 40/.04. The instruments were evaluated prior to your use and after two, four, six and eight use in simulated acrylic resin canals. These canals were standardized and their curvature was 35 degrees and their final length 18 mm, being this point reached at the end of the instrumentation in both systems. The variable in question was measured in degrees until the time of instrument fracture, obtained through a modified Troptômetro. The values registered at the time of fracture, for each instrument, were submitted to statistical analysis using the Wilcoxon test, Mann-Whitney U Test for comparison between the two systems of instrumentation (p ≥ 0.05). The results showed that both instruments did not show differences when evaluated without any use, after two uses, four uses, six uses and finally eight uses (p ≥ 0.05). It was concluded that TF Adaptive systems and Hyflex CM showed similarity as resistance to torsion fracture.

Objective: The objective of this work is to analyze the literature database on the relationship between neonatal hypoxia and epilepsy, catalog the data and provide a list of relevant works for the academic community in the health area. Methodology: this is a literature review, making a search in databases of the platforms PUBMED, Scielo and Jornal Capes, with the application of language filters, selecting english, portuguese and spanish, German for using only the works of both last five years and with bibliographic relevance. The Health Sciences Descriptors used ​​for: Neonatal Hypoxia; Epilepsy; Asphyxia. Results: scientific articles considered relevant to demonstrate the relationship between neonatal hypoxia and epilepsy, and its consequences demonstrate the need for adequate prenatal care and humanized delivery for the mother and the newborn. It is necessary for a multidisciplinary team to accompany the pregnant/parting woman, analyzing her needs and possible complications that may occur during or during childbirth.

Resumo O Brasicystis bennetti n. gen., n. sp. (Trematoda: Digenea: Didymozoidae) foi descrito da pescada, Plagioscion squamosissimus, um peixe amazônico de grande valor comercial. Este parasita foi encontrado nos tecidos subcutâneos da boca e opêrculos, e dentro de cistos ovalados colgados nas brânquias. A presença destes helmintos debaixo da pele causou manchas amarelas visíveis, devido às acumulações de grandes números de ovos. A nova forma é a terceira espécie de Didymozoidae citada de água doce no mundo. Caracterizou-se por ter a parte posterior do corpo com uma dobra ventral (anterior) e o restante achatado lateralmente e curvado ventro-lateralmente. Tinha também um único testículo tubular, estendendo-se posteriormente ao ovário, que tem a mesma forma. Estes trematódeos tinham um comprimento total até 19 mm e ovos muito pequenos (8x16 µm).

Abstract A new species of dermestid beetle, Caccoleptus honeymani, is described, the first known member of the genus from Brazil. Notes are given on another Brazilian species of the genus, which is not formally named at this time.

Resumo Fêmeas adultas do vespídeo Angiopolybia pallens (Lepeltier) foram observadas alimentando-se do material do ninho, ovos e girinos do ninho de espuma construído pela rã Leptodactylus pentadactylus (Laurenti) próximo de Manaus, Brasil. Larvas e adultos de moscas de efidrídeos, Gastrops willistoni Cresson, foram encontrados em todos os ninhos de espuma de L. pentadactylus encontrados entre 15 de julho a 21 de dezembro de 1978. As larvas provavelmente alimentam-se de ovos não desenvolvidos, material do ninho e dos corpos de insetos que tinham ficado presos no material viscoso. Um eucoilídeo parasito de larvas de efidrídeo foi observado "in situ" e criado em laboratório das coletas de campo de larvas de G. willistoni. Associações esporádicas adicionais são também assinaladas. Fêmeas adultas de Angiopolybia obidensis (Ducke) foram observadas em uma ocasião comendo a gelatina ao redor dos ovos de rã (hylídeo), Osteocephalus taurinus Sleindachner.

Resumo Alguns aspectos da biologia de Limnogonus recurvus (Gerridae: Hemiptera) foram estudados no laboratório. Os adultos e ninfas foram capturados em vários tipos de habitats aquáticos, como: rios, igarapés, lagos e pequenas poças de água pluvial. Os cruzamentos foram efetuados no laboratório. O ciclo de ovo a adulto é de aproxidamente 43 dias.

Abstract New Brazilian species of Musapsocus (1), Thyrsopsocus (1), Psococerastis (1), Metylophorus (1), Psocidus (1). Myopsocus (1), Phlotodes (1), and Lophopterygella (2) are described and figured, and augmented descriptions given of Cervopsocus medialis New and Psocidus quadrisignatus (Banks). Musapsocus and Lophopterygella are here recorded from Brazil for the first time.

Resumo Com base em observações do abdome pupal de algumas espécies neotropicais de Simuliini e Prosimuliini, sem o uso do KOH (Hidróxido de Potássio) como agente "limpador-clarificante", são propostas algumas alterações nas definições apresentadas por Crosskey (1969) e por Wygodzinsky & Coscarón (1973) para estas tribos: Simuliini com áreas membranosas estriadas longitudinais medianas nos esternitos V, VI-VII e algumas vezes também no VIII; Prosimuliini somente apresentando áreas estriadas membranosas longitudinais, medianamente, nos esternitos VI-VII e algumas vezes também no VIII.

Summary Some compounds present in the wood of Torresia acreana Ducke (Leguminosa, Lotoideae) were identified. Coumarin, vanillic acid, the terpenoids campesterol, stigmasterol, sitosterol, cycloeucalenol, 24-methylene cicloartanol and cycloartenol and some fatty acids chiefly oleic, palmitic and linoleic acids had their presence established by chromatographic and spectrometric methods. The allelopathy of these compounds was discussed.
