Scientific collaboration network among Brazilian universities: an analysis in Dentistry area

This paper analyses the scientific collaboration network formed by the Brazilian universities that investigate in dentistry area. The constructed network is based on the published documents in the Scopus (Elsevier) database covering a period of 10 (ten) years. It is used social network analysis as the best methodological approach to visualize the capacity for collaboration, dissemination and transmission of new knowledge among universities. Cohesion and density of the collaboration network is analyzed, as well as the centrality of the universities as key-actors and the occurrence of subgroups within the network. Data were analyzed using the software UCINET and NetDraw. The number of documents published by each university was used as an indicator of its scientific production.

El área de gestión de la información y del conocimiento como frente de investigación en la Ciencia de la Información brasileña: análisis de la producción científica en el período 2000-2009

The management of information and knowledge has been one of the areas of expertise of the fastest growing Brazilian information science. The purpose of this work is to observe how this research front structure from the point of view of the subjects that compose and intellectual frameworks which supports. For this we have analyzed the content of scientific production published in four majo r national journals of the discipline: Ciência da Informação, DataGramaZero, Perspectivas em Ciência da Informação and Transinformação over 2000-2009. The methodology is based on co-occurrence analysis of keywords of articles and co-citation analysis of authors. For the representation and interpretation of the results are used to social network analysis (SNA). We conclude that both information management and knowledge management are closely linked areas within topics including approaches but no consensus answer from the point of view of intellectual frameworks referenced.

A palavra poética de Arnaldo Antunes

This article reflects on Arnaldo Antunes‟ (AA) poetics. For this purpose, both the contributions of Fontanille and Zilberberg regarding tensivity, as well as some ideas of Tatit regarding song semiotics. The aim is to think about how the dance between enunciation and enunciate is structured in AA within poetical architecture as exemplified here based on the analysis of the poem “Palavra”. The hypothesis is that the tension between the two central nuclei of the poem, metalanguage and erotism, are the essential compositional marc of AA poetical stylistics. The results lead to the reflection that the musical tension is the game that guarantees the movement between the density of the word and the erotic fluidity of the authorial (metalinguistic) act of production.

Mirabegron relaxes urethral smooth muscle by a dual mechanism involving β3-adrenoceptor activation and α1-adrenoceptor blockade

Mirabegron is the first β3-adrenoceptor (AR) agonist approved for treatment of overactive bladder syndrome (OAB). This study aimed to investigate the effects of β3-adrenoceptor (AR) agonist mirabegron in mouse urethra. The possibility that mirabegron exerts α1-AR antagonism was also tested in rat smooth muscle preparations presenting α1A- (vas deferens and prostate), α1D- (aorta) and α1B-AR (spleen). Functional assays were carried out in mouse and rat isolated tissues. Competition assays for the specific binding of [(3) H]Prazosin to membrane preparations of HEK 293 cells expressing each of the human α1-ARs, as well as β-AR mRNA expression and cyclic AMP measurements in mouse urethra were performed. Mirabegron produced concentration-dependent urethral relaxations that were right shifted by the selective β3-AR antagonist L 748,337, but unaffected by β1- and β2-AR antagonists (atenolol and ICI 118,551, respectively). Mirabegron-induced relaxations were enhanced by the phosphodiesterase-4 inhibitor rolipram, and this agonist stimulated cAMP synthesis. Mirabegron also produced rightward shifts in urethral contractions induced by the α1-AR agonist phenylephrine. Schild regression analysis revealed that mirabegron behaves as a competitive antagonist of α1-AR in urethra, vas deferens and prostate (α1A-AR, pA2  ≅ 5.6) and aorta (α1D-AR, pA2  ≅ 5.4), but not in spleen (α1B-AR). The affinities estimated for mirabegron in functional assays were consistent with those estimated in radioligand binding with human recombinant α1A- and α1D-ARs (pKi ≅ 6.0). The effects of mirabegron in urethral smooth muscle are the result of β3-AR agonism together with α1A / α1D-AR antagonism.

Detecção de co-infecções por Leishmania (l.) chagasi, Trypanosoma evansi, Toxoplasma gondii e Neospora caninum em cães

Co-infections by Leishmania (L.) chagasi, Trypanosoma evansi, Toxoplasma gondii and Neospora caninum in dogs were investigated. Amastigotes forms of Leishmania spp. were detected by cytopathological analysis of lymph nodes in 46,42% (39/84) of dogs. In a male dog, adult, without defined breed, from rural area and positive for Leishmania, were observed flagellated forms of T. evansi in blood smear. By immunofluorescence antibody test, 5,95% (5/84) of dogs were considered reactive to T. gondii, with titer equal to or higher than 1:64, while 3,57% (3/84) were reactive to N. caninum, with titer ≥1:50. Among the animals with visceral leishmaniasis, one showed positive serological response to T. gondii and two for N. caninum. All dogs reactive to N. caninum were from rural area and the predominance of infection by T. gondii was in dogs from urban area. A young male dog from the rural area and seropositive for T. gondii showed Ehrlichia spp. morulae in the cytology and positive reaction for canine distemper virus. Thus, further studies are needed to assess the epidemiology of these infections in canine population, especially with respect to the reservoirs of Trypanosoma spp. in rural areas.

Efeito da clorexidina na cicatrização umbilical de avestruzes

The contamination of the umbilical region of newly hatched ostriches is one of the major problems in the bird production. This work aimed to evaluate the umbilical healing of ostriches (Struthio camelus) through the use of chlorhexidine as antiseptic associated to the total or partial umbilical cord cut off. It was used 168 newly hatched ostriches of which the umbilical cords were either sectioned totally or 0.5 cm above their insertion. The umbilical region antisepsis consisted of topical administration of an aqueous or alcoholic solution of chlorhexidine, 0.5, 1.0 or 2.0% during three days. A group of non-treated animals was added also. The umbilical healing was evaluated in the ostriches at 14 and 28 days of age. Results showed that all the chlorhexidine solutions reduced the risk of omphalitis, being the alcoholic solution 2% the most efficient. Umbilical healing was faster in animals in which the umbilical cord was totally cut off. It can be concluded that the use of chlorhexidine as antiseptic for newly hatched ostriches is safe and favors the umbilical healing. Moreover, for a better effectiveness it is necessary to remove the umbilical cord in its insertion
